Mold of double-mold-core structure and for dust cover of automobile steering device

Abstract

The invention discloses a mold of a double-mold-core structure and for a dust cover of an automobile steering device. Each mold core is composed of two mold pieces which are detachably connected. Notches are formed in a middle mold body. A detachable cross beam is arranged at the notches. The mold cores are located at the notches. The two mold pieces of each mold core are installed on the middle mold body and the cross beam correspondingly. After a product is molded, an upper mold body and a lower mold body are opened, and then the two mold pieces of each mold core are dismantled by opening the cross beam, so that rapid demolding of the product is achieved, the demolding efficiency is greatly improved, and secondary damage to the product is avoided; in addition, the mold cores and the middle mold body are of an integrated structure so that scattered parts can be collected and sorted conveniently. The mold of the double-mold-core structure and for the dust cover of the automobile steering device is simple in structure and reasonable in design; each mold core is designed to be of a two-section structure, the two sections of each mold core are fixed to the middle mold body and the cross beam correspondingly, and thus the demolding efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of automobile steering gear processing, in particular to a double-core structure mold for an automobile steering gear dust cover. Background technique [0002] The automobile steering gear dust cover is used in the automobile steering system. The rubber part is connected with the steering connecting rod to prevent dust, prevent friction, and convert the rigid connection into a flexible connection. The material is ethylene propylene rubber (EPDM) , Ethylene propylene material is tasteless and non-toxic, in line with international RoHS safety standards. In the actual processing process, the product size is large and the structure is complex. To meet the needs of product demoulding, movable cores are designed at both ends. Workers need to move the core for demoulding. The labor intensity is high, the core is easy to bump, and single-cavity molding The production efficiency is low, the processing of mold core i...
