Specific embodiment
The embodiment of the present invention is described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning to endSame or similar label indicates same or similar element or element with the same or similar functions.Below with reference to attachedThe embodiment of figure description is exemplary, it is intended to is used to explain the present invention, and is not considered as limiting the invention.
Refrigeration equipment end cap 10 according to an embodiment of the present invention is described in detail below with reference to Fig. 2-Fig. 3.
Referring to shown in Fig. 2, after refrigeration equipment end cap 10 according to an embodiment of the present invention may include end cap upper plate 1 and end capPlate 2.In some embodiments, end cap back plate 2 can be vertically arranged with end cap upper plate 1.
Further, end cap upper plate 1 may include light filling bar 11, changeover portion 12 and thick section 13.Specifically, changeover portion 12 connectsIt connects between light filling bar 11 and thick section 13, the thickness of thick section 13 is greater than the thickness of light filling bar 11, and changeover portion 12 slows down end cap upper plate 1Thickness changing trend, so that the thickness change transition between thick section 13 and light filling bar 11 is steady, this is conducive to mention to a certain extentThe intensity of high refrigeration equipment end cap 10.
Further, the width c of light filling bar 11 and the thickness b of light filling bar 11 meet relational expression respectively: 2.2mm≤b≤2.3mm,The back edge of light filling bar 11 is arranged in 4mm≤c≤6mm, end cap back plate 2.
For existing refrigeration equipment end cap, in injection molding process, the 1 surface meeting of end cap upper plate of refrigeration equipment end capStress trace color difference 30 is generated, as shown in Figure 1, not only influencing the appearance of product in this way, but also has an effect on the intensity of product.
To solve the problems, such as that stress trace color difference 30 is serious, the present inventor changes from the aspect of product structure, andMold flow analysis is carried out with Moldflow, stress analysis is carried out to 10 surface of refrigeration equipment end cap, by changing refrigeration equipment endThe cross section parameter of lid 10, optimization refrigeration equipment end cap 10 section design, with solve 10 surface of refrigeration equipment end cap dark color andColored stress trace color difference 30.
By simulation analysis, it is known that when the wall thickness of thick section 13 is that definite value (such as will be detailed below mentioning the wall of thick section 13Thick a=2.5mm) when, stress trace color difference 30 is very big with the wall thickness relationship of light filling bar 11.
Specifically, stress trace color difference 30 is serious, and weld mark is shorter as the wall thickness b=2.0mm of light filling bar 11.Work as light filling barWhen 11 wall thickness b=2.3mm, stress trace color difference 30 is slight, weld mark moderate length.As the wall thickness b=2.5mm of light filling bar 11,Unstressed trace color difference 30, weld mark is longer.Conclusion is as shown in the table:
| The wall thickness (unit: mm) of light filling bar 11 | Stress trace color difference 30 | Weld mark |
| 2.0 | Seriously | It is shorter |
| 2.3 | Slightly | It is moderate |
| 2.5 | Nothing | It is longer |
By analyzing comparison above as can be seen that can effectively solve the problem that weld bond as the thickness b=2.3mm of light filling bar 11With the contradiction of stress trace color difference 30.Further being analyzed by using Moldflow simulation software can obtain, and the present inventor mentionsThe thickness b of light filling bar 11 is designed out are as follows: 2.2mm≤b≤2.3mm, in addition, again due to wall thickness b, the light filling bar of weld mark and light filling bar 1111 width c has much relations, therefore proposes to design the width c of light filling bar 11 are as follows: 4mm≤c≤6mm, so as to protectUnder the premise of card weld mark is moderate, the stress trace color difference 30 on 10 surface of refrigeration equipment end cap is effectively relieved, even is eliminated stress traceColor difference 30 makes 10 surface of refrigeration equipment end cap that qualified color 20 be presented, further, it is also possible in certain journey to promote exterior qualityIncrease the intensity of refrigeration equipment end cap 10 on degree.
In some alternative embodiments, the thickness b of light filling bar 11 can be 2.25mm, and the width c of light filling bar 11 can be4.5mm, but not limited to this.
Refrigeration equipment end cap 10 according to an embodiment of the present invention, by limiting the thickness b of light filling bar 11, the width c of light filling bar 11Size, can not only effectively solve the problems, such as that 10 surface weld mark of refrigeration equipment end cap is too long, but also can eliminate it is dark,Colored stress trace color difference 30, to greatly promote the exterior quality of refrigeration equipment end cap 10.
In an embodiment of the present invention, the width d of changeover portion 12 meets relational expression: 4mm≤d≤6mm.For example, d=5mm.
Further optionally, the width d of changeover portion 12 can be equal with the width c of light filling bar 11, i.e. d=c.
In some embodiments, the thickness a of thick section 13 meets relational expression: a=2.5mm.
When thick section 13 and the Wall-Thickness Difference of light filling bar 11 are 0.5mm (i.e. a=2.5mm, b=2.0mm), stress trace color difference 30 is tightWeight, weld mark are shorter.When thick section 13 and the Wall-Thickness Difference of light filling bar 11 are 0.2mm (i.e. a=2.5mm, b=2.3mm), stress trace colorPoor 30 is slight, weld mark moderate length.When thick section 13 and the Wall-Thickness Difference of light filling bar 11 are 0mm (i.e. a=2.5mm, b=2.5mm),Unstressed trace color difference 30, weld mark is longer.
The thickness e of end cap back plate 2 meets relational expression: 2.8mm≤e≤3.0mm.For example, e=2.9mm.
Optionally, pass through arc transition between the inner surface 121 of changeover portion 12 and the inner surface 111 of light filling bar 11.The circular arcThe variation tendency for being conducive to alleviate changeover portion 12 to light filling bar 11, so that injection molding process is more smooth.
Further, circular arc R meets relational expression: 10mm≤R≤30mm.For example, R=20mm.
Optionally, thus the flush with outer surface of the outer surface of changeover portion 12 and light filling bar 11 can guarantee the appearance of end cap upper plate 1Face is smooth, to further promote the exterior quality of refrigeration equipment end cap 10.
Optionally, the angle β of thick section 13 and end cap back plate 2 meets relational expression: 45 °≤β≤140 °.For example, β=100 °mm。
The refrigeration equipment of embodiment according to a further aspect of the invention, the refrigeration equipment end cap 10 including above-described embodiment.ThisThe invention refrigeration equipment end cap 10 can be refrigerator door end cap, is also possible to refrigerator doors end cap, can also be other refrigerationThe end cap of equipment.
Although the embodiments of the present invention has been shown and described above, it is to be understood that above-described embodiment is exampleProperty, it is not considered as limiting the invention, those skilled in the art within the scope of the invention can be to above-mentionedEmbodiment is changed, modifies, replacement and variant.
