Air spring capsule die convenient for blank taking

Abstract

The invention provides an air spring capsule die convenient for blank taking. The air spring capsule die comprises a die body and die core fixedly arranged in the die body, wherein an annular closed vulcanization cavity is formed between the die body and the die core; the die body comprises an upper die, a middle die and a lower die, which are adaptively and closely arranged; the upper end of the upper die is fixed on a vulcanization machine; the middle die comprises a die disk and die clacks matched with the lower end face of the die disk; the die clacks comprise fixed die clacks fixed on the die disk and movable die clacks which do motion relative to the fixed die clacks in the radial direction of the die body; the fixed die clacks and the movable die clacks are intercrossed in pairs; a guide rod perpendicularly penetrates through the side surfaces of the middle die and the lower die and is connected with a cylinder of the vulcanization machine; inclined guide structures matched with the movable die clacks are arranged on the middle die and the lower die and are used for controlling the movable die clacks to be opened and closed. The air spring capsule die disclosed by the invention has the beneficial effects of simple structure and convenience in opening, closing and product taking; the time and the labor are saved; the contact with a product is avoided in a process of opening the die to take out the product; joints of the die clacks achieve effects of exhausting air; the product has a smooth surface and is high in smoothness.

Description

technical field [0001] The invention relates to the technical field of air springs, in particular to an air spring capsule mold which is convenient for taking embryos. Background technique [0002] An air spring is a form of spring made of the elasticity produced by compressed air. At present, it is mainly used in the shock absorber system of various vehicles. [0003] The traditional air spring capsule mold is a combination of upper and lower molds. This method is suitable for cylindrical capsules. In recent years, capsules with folded bottoms have appeared on the market. This kind of capsules is formed by traditional molds. When taking out the product, it needs to be supported by a jig The surface of the capsule, and because only the upper and lower molds are matched, only the gap at the junction can be exhausted, and the product surface quality is not high. [0004] In order to improve the defects of the prior art, a mold with upper, middle and lower molds appeared on t...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the defects of poor exhaust effect and difficult removal after vulcanization of the air spring capsule in the prior art, the present invention provides an air spring capsule mold that is easy to take embryos. Cooperate with each other, and use the cylinder of the vulcanizing machine to control the movement of the mold flap relative to the fixed mold flap, with simple structure and easy operation
