In fig. 1-3: 1. a lower die; 2. an upper die; 3. filling the bumps; 4. a movable module; 5. a sole molding cavity; 6. hanging the step; 7. a connecting lug; 8. a connecting groove; 9. a bolt; 10. grooving; 11. a cutter; 12. a seal ring; 13. positioning columns; 14. a positioning groove; 15. and (3) buffering rubber.
Detailed Description
The following description of the embodiments of the present utility model will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
It should be noted that, if directional indications (such as up, down, left, right, front, and rear … …) are included in the embodiments of the present utility model, the directional indications are merely used to explain the relative positional relationship, movement conditions, etc. between the components in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indications are correspondingly changed.
The utility model provides a sole forming die convenient to replace.
In this embodiment, referring to fig. 1-3, this sole forming die convenient to change, including articulated lower mould 1 and last mould 2 each other, be equipped with the filling lug 3 of shoes formula on the last mould 2, still include the movable module 4 of embedding installation in the embedding intracavity of lower mould, be equipped with in the movable module 4 with the sole forming cavity 5 of above-mentioned filling lug looks adaptation, be equipped with on the outer fringe of movable module and hang by step 6, it is equipped with engaging lug 7 to hang by step 6 both sides, it is equipped with engaging lug card income spread groove 8 to inlay the chamber both sides, it is fixed through bolt 9 after the engaging lug card goes into above-mentioned spread groove.
Among the above-mentioned technical scheme, increase the movable mould that has set up sole molding chamber, and movable mould carries out detachable connection through bolt and lower mould, so when the sole of different lines of needs production, only need with movable mould follow lower mould and pull down, then change the movable mould of different lines can, need not to dismantle the change to whole mould, improve production efficiency greatly.
Specifically, a cutting groove 10 is formed in the periphery of the sole forming cavity, a cutter 11 is arranged on the outer ring of the filling lug, and the cutter 11 can be just clamped into the cutting groove 10 after the lower die and the upper die are clamped; the cutting groove is of a V-shaped structure.
According to the technical scheme, through the arrangement of the cutters and the cutting grooves, redundant parts of the outer edge of the sole forming cavity can be cut off, the parts of the outer edge of the sole are reduced, and the follow-up polishing workload is reduced.
Specifically, an annular groove is formed in the outer ring of the hanging step, and a sealing ring 12 is arranged in the annular groove.
By arranging the sealing ring, the sealing performance in the process of die assembly is improved.
Specifically, positioning columns 13 are arranged on four corners of the upper die, and positioning grooves 14 corresponding to the positioning columns 13 are arranged on four corners of the lower die; the positioning column 13 and the positioning groove are of frustum structures; the top of the positioning column 13 is provided with buffer rubber 15.
In the technical scheme, the positioning column and the positioning groove are mutually matched to play a role in positioning, and in addition, buffer rubber is arranged at the top of the positioning column to play a role in buffering and noise reduction.
