Automatic disc spring sealing compound ejection die

Abstract

The invention discloses an automatic disc spring sealing compound ejection die. The automatic disc spring sealing compound ejection die comprises an upper die, a middle die, a lower die plate and an ejection mechanism. The upper die is located above the middle die, and is provided with a compound injection opening penetrating the upper end face and the lower end face of the upper die, the end, close to the middle die, of the upper die is provided with a first protrusion part, and a groove is formed in the end of the first protrusion part; the middle die is located above the lower die plate and fixedly installed on the lower die plate, the middle die is provided with a die cavity, a disc spring is arranged at the bottom of the die cavity, and a movable die core is arranged in the die cavity; the upper surface of the movable die core is provided with a second protruding part for a frame inner hole to penetrate, the lower surface of the movable die core abuts against the disc spring, in the die assembly state, a second protrusion part extends into the groove in the end of the first protrusion part, molding cavities are formed on the peripheries of the second protrusion part and the first protrusion part, and the compound injection opening is communicated with the molding cavities; and the ejection mechanism is used for ejecting out materials in the molding cavities. The automatic disc spring sealing compound ejection die is simple and reliable in operation, the manual cost and the labor intensity are reduced, and very high competitive force is achieved on the market.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to an automatic ejection mold for disc spring sealing glue. Background technique [0002] The shock absorbing pads of car doors were assembled with pure rubber in the early stage, but with the improvement of living standards, people are more and more optimistic about the safety performance and comfort of cars. Pure rubber is easy to fall off after wear, so This product requires rubber to reduce noise, and a skeleton to ensure the strength and durability of the product. As a result, a product that combines a skeleton and a rubber body (such as figure 1 As shown, A in the figure represents the frame, B represents the rubber body), the principle of this product is to reserve an inner hole on the frame of the product, and when in use, it can be fixed with the car by screws. And this kind of structural setting makes the rubber body in the vulcanization process during the production of th...

AI Technical Summary

Problems solved by technology

And this kind of structural setting makes the rubber body in the vulcanization process during the production of this product, and its rubber liquid is easy to overflow into the inner hole of the skeleton, and it is necessary to remove the flash, and the removal of the flash requires a lot of labor. If it is not removed Clean, it will also cause the bolts to be poorly assembled or even impossible to assemble
