Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility modelClearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than wholeEmbodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative workEvery other embodiment obtained, fall within the protection scope of the utility model.
The utility model provides a kind of refractory brick molding as shown in Figs 1-4 and makes mold tool, including lower mold 8 and upper moldTool 2, the inner bottom surface of the lower mold 8 are fitted with liftout bottom plate 13, are fixed with grafting cylinder in the middle part of the lower end surface of the lower mold 811, the middle part of the liftout bottom plate 13 is fixed with the ejector beam 12 across grafting cylinder 11, before the two side walls of the lower mold 8Fixed link 7 is mounted on rear end face, the fixed link 7 positioned at lower 8 front and back of mold is each passed through front apron 10 and rear gearPlate 5, the outside that front apron 10 and rear baffle 5 are located in the fixed link 7 are fixed with limited block 6, the front apron 10 and rear gearThe equal lateral surface of plate 5 is provided with piston rod fixing seat 9, and the side that lower die tool 8 is located on the front apron 10 and rear baffle 5 is equalIt is fixed with side Forming press 4, the top closure of the lower mold 8 has upper mold 2, and the bottom surface of the upper mold 2 is fixed withThe upper surface middle part of upper Forming press 3, the upper mold 2 is fixed with by connection beam barrel 1.
Specifically, symmetrically opening up on the front/rear end of the two side walls of the lower mold 8, there are two threaded holes, described solidThe fixed fastening screw 14 in the end of fixed pole 7, the fixed link 7 are screwed solid with lower mold 8 in threaded hole by fastening screw 14It is fixed.Fixed link 7 is fixed on lower mold 8, while convenient for dismantling to fixed link 7, replacing front apron 10 and rear baffle 5.
