During the whole automatic demoulding process, use the lower insert 24 to cooperate with the hooks of the inner and outer valve molds in the vertical direction to realize the automatic separation of the middle mold assembly 4 and the lower mold assembly 2, and use the inclined stay plate 13 fixed on the bottom plate 11 Cooperate with the cone surface of the inner and outer valve molds to realize the reverse movement of the inner and outer valve molds along the horizontal direction, so as to realize the automatic separation of the inner and outer valve molds from the product, and use the ejector rod assembly 26 to lift the product to the lower insert 24 and mold core 25 Automatic disengagement, the parts in the mold cooperate with each other, and the automatic demoulding of the product can be realized only by the movement of various parts of the vulcanizing machine and the cooperation of various parts inside the mold.

Wherein, the quantity of described lower mold assembly 2 is a plurality of, and a plurality of lower mold assemblies 2 are arranged side by side between upper mold assembly 3 and bottom mold assembly 1, and described middle mold assembly 4 There are a plurality of tapered cavities B corresponding to the lower mold assembly 2, and one lower mold assembly 2 is clamped in one tapered cavity B. It can be seen from the drawings that a lower mold assembly 2 is arranged between the upper mold assembly 3 and the bottom mold assembly 1, and the middle mold assembly 4 has two tapered cavities B corresponding to the lower mold assembly 2 , two products can be produced in one vulcanization, which can effectively improve the vulcanization efficiency of the product. In actual application, according to the space size of the production site and the size of the vulcanizer, the number of lower die components 2 can also be appropriately increased to meet the product requirements. production requirements.

Wherein, the middle mold assembly 4 includes a middle mold 41 with a plurality of conical cavities B and a fastener 42 fixed on the top of the middle mold 4, and the middle mold 41 is fixed to the hanger frame of the vulcanizer, The outer walls of the outer petal mold 21 and the inner petal mold 22 cooperate with the conical surface of the conical cavity B in the middle mold 41 respectively, and are clamped in the conical cavity B, and the upper insert 23 and the buckle Part 42 taper fits, and is fastened by fastener 42. As shown in Figure 1, the outer valve mold 21 and the inner valve mold 22 are clamped in the tapered cavity B, and the upper insert 23 is fastened by the fastener 42 through the tapered surface. When the demoulding starts, the vulcanizer is heated When the plate moves down, because the tapered cavity B clamps the outer valve mold 21 and the inner valve mold 22, and the fastener 42 fastens the upper insert 23, under the action of gravity, clamping force and fastening force , the middle mold assembly 4 and the lower mold assembly 2 will move down together with the bottom mold assembly 1 as the lower heating plate of the vulcanizer moves down.

Specifically, the outside of the bottom edge of the upper insert 23 is a stepped edge, and the upper insert 23 is placed on the inner flap mold 22 and the outer flap mold 21 through the stepped edge, and the outer surface of the upper insert 23 is a tapered surface, The top of the outer side of the outer petal mold 21 has several stepped grooves 21.1 distributed at intervals, and the fastener 42 extends into the stepped grooves 21.1 to cooperate with the tapered surface of the outer side of the upper insert 23 to press the upper The outer side of the insert 23.

When the jack C is vertically aligned with the ejector rod 26.2, the ejector rod 26.2 passes through the movable jacking plate 11.1 and is inserted into the bottom plate In 11, when the jack C and the ejector rod 26.2 are vertically staggered, the ejector rod 26.1 is against the movable jacking plate 11.1. It can be seen from the drawings that there are two sets of ejector rod assemblies in a lower mold assembly 2, which are respectively in contact with two pieces of metal used for the elastic support of the vulcanized bearing pad gearbox, and in order to prevent the rubber from being damaged when the product is jacked up. layer, the upper edge of the arc-shaped top plate 26.2 is processed into rounded corners, and each set of ejector pin assemblies corresponds to a movable jacking plate 11.1, and the ejector pin 26.2 can be aligned with the jack C or Staggered, so that the push rod 26.2 is inserted into the bottom plate 11 or abuts against the movable lifting plate 11.1. In the process of automatic film removal, by changing the displacement of the moving lifting plate 11.1 on the bottom plate 11, the ejector rod assembly 26 is abutted against the moving lifting plate 11.1. After the inner and outer valve molds are opened, the process of moving down the supporting plate 12 In the process, the jacking of the product is realized, thereby realizing the automatic disengagement of the lower insert 24 and the mold core from the product.

Specifically, the outer edge of the bottom of the lower insert 24 has an outwardly protruding rib 24.1, and the bottom of the inner wall of the inner valve mold 22 and the outer valve mold 21 has a groove D that is wedged with the rib 24.1, The rib 24.1 is inserted into the groove D so that the lower insert 24 cooperates with the inner valve mold 22 and the outer valve mold 21 along the vertical direction.
