Automatic opening and closing mold for V-shaped metal rubber spring and automatic mold opening and closing method thereof

Abstract

The invention provides an automatic opening and closing mold for a V-shaped metal rubber spring and an automatic mold opening and closing method thereof. The automatic opening and closing mold comprises an upper mold assembly and a lower mold assembly; the upper mold assembly comprises a top plate, a rubber injection plug, a rubber injection barrel, a middle mold, an upper insert and a middle moldheating ring; the lower mold assembly comprises a bottom mold, a supporting plate, two side inserts, a lower insert and a petal mold combination; two floating plates, four wedge-shaped blocks and four wedge-shaped grooves are further included; and the floating plates vertically move in the supporting plate to drive front petal molds and rear petal molds to vertically move, one wedge-shaped blockis arranged at every two adjacent petal molds, the supporting plate drives the petal mold combination to be vertically separated from the bottom mold, and the front petal molds and the rear petal molds are separated from cavities through horizontal movement under the action of the wedge-shaped blocks and vertical downward movement of the floating plates. According to the invention, the operation labor intensity is greatly reduced; the mold is automatically opened, the cavities are automatically separated, the product is directly taken out, the product has no appearance damage, and the productpercent of pass is improved; and the mold opening and closing time is short, and the product production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of moulds, in particular to a V-shaped metal rubber spring automatic mold opening and closing mold and an automatic mold opening and closing method thereof. Background technique [0002] like figure 1 and figure 2 The V-shaped metal rubber spring is shown. The V-shaped metal rubber spring is a composite of rubber 1 and metal parts 2. It is arranged between the axle box and the bogie frame, and is used to support the vehicle and load weight, transmit the guiding force of the wheel set, Transmit braking and traction, provide vertical buffer and horizontal buffer. In the prior art, after the vulcanization of the V-shaped metal rubber spring product, the mold is completely manually removed, and it needs to rely on crane hoisting, tooling, crowbar, mallet and other auxiliary demoulding. The production efficiency is low, the operation is complicated and labor-intensive, and the product Very vulnerable to damag...

In the prior art, after the vulcanization of the V-shaped metal rubber spring product, the mold is completely manually removed, and it needs to rely on crane hoisting, tooling, crowbar, mallet and other auxiliary demoulding. The production efficiency is low, the operation is complicated and labor-intensive, and the product highly vulnerable

[0003] The patent with authorized notification number CN106926397B provides a kind of inclined rubber layered spring automatic opening and closing mold and its automatic opening and closing method. The mold and the opening and closing method provided by the invention are used for an inclined rubber layered spring The product structure of the inclined rubber layered spring is horizontally inclined, surrounded by a layered ring structure. During the automatic mold ejection process, the four petal molds can be moved horizontally, and there is no problem of mold undercut; the technical solution If the mold described above is used to produce the V-shaped metal rubber spring of the present invention, because the V-shaped metal rubber spring has opposite profiles on both sides to be at a V angle, if the four petal molds all move horizontally, the two V-shaped side profiles will There is an undercut in the mold, that is, it is impossible to realize the automatic side core pulling of the V-shaped metal rubber spring.
