A V-shaped metal rubber spring automatic mold opening and closing mold and automatic mold opening and closing method

Abstract

The invention provides a V-shaped metal rubber spring automatic mold opening and closing mold and an automatic mold opening and closing method, including an upper mold assembly and a lower mold assembly, and the upper mold assembly includes a top plate, a plastic injection plug, a plastic injection barrel, middle mold, upper insert and middle mold heating ring; the lower mold assembly includes a bottom mold, a support plate, two side inserts, a lower insert and a valve mold combination; it also includes two floating plates, four Wedge-shaped block and four wedge-shaped grooves; the floating plate moves vertically in the support plate, driving the vertical movement of the front and rear valve molds, the wedge-shaped block is set at the adjacent two valve molds, and the support plate drives the combination of the valve molds and the bottom mold vertically Separation, the front and rear lobe molds are synthesized by the horizontal movement under the action of the wedge block and the vertical downward movement of the floating plate to achieve separation from the cavity. The invention greatly reduces the operation labor intensity; the mold is automatically opened, the cavity is automatically separated, the product is directly taken out, the product has no appearance damage, and the qualified rate of the product is improved; the mold opening and mold closing time is short, and the product production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of molds, and more particularly, to a V-shaped metal rubber spring automatic mold opening and closing mold and an automatic mold opening and closing method. 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 part 2, which is arranged between the axle box and the bogie frame to support the weight of the vehicle and the load, transmit the guiding force of the wheel set, It transmits braking and traction, and provides vertical and horizontal buffering. In the prior art, after the vulcanization of the V-shaped metal rubber spring product is completed, it is completely manually released from the mold, and it needs to rely on crane lifting, tooling, crowbar, mallet, etc. to assist in demoulding, resulting in low production efficiency, complicated operation and high labor intensity. Very easily...

Problems solved by technology

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.
