Description

Bidirectional sequential core-pulling device

Technical Field

The utility model relates to an improvement invention of a core-pulling device, in particular to an improvement invention of a bidirectional sequential core-pulling device for oil cups and bracket products.

Background

Plastic parts in automobile parts are mostly produced and manufactured by using an injection mold. Some plastic accessory product structures and features have different directional undercuts designed on multiple sides of the product cavity for reasons of assembly layout or construction. When the injection mold is used for production, after the product is poured, the part for inner cavity molding needs to be pulled out of the mold. Because the inner cavity of the product has the back-off in different directions on multiple sides, under normal conditions, the die-drawing of the inner cavity can be smoothly realized by independent slide block movement in different directions or manual insert demoulding. For the assembly with a plurality of independent sliders in different directions, the number of parts forming the assembly is large, and the manufacturing and processing cost is high; the problems of flashing, product segment difference and the like easily caused by assembly abrasion exist; due to the structural reasons, the space of a plurality of dies is small, all components cannot be accommodated, and the dies cannot move due to mutual interference; after the part is demoulded, the insert needs to be manually separated, so that the forming period and the product quality are influenced.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that overcome prior art not enough, provide a simple structure, the fashioned two-way order of being convenient for device of loosing core

In order to solve the technical problem, the utility model discloses an adopt following technical scheme to realize: this kind of two-way order device of loosing core, including symmetrical arrangement's left mount pad and right mount pad, its characterized in that: the left and right mounting seats are respectively provided with a sliding groove, a sliding block capable of moving left and right is arranged in the sliding groove, the sliding block is provided with a driving structure in a matching mode, the inner end of the sliding block is connected with a first molding module, a first molding cavity and an opening which are distributed up and down are formed in the inner end face of the first molding module, a second molding module capable of lifting is matched and arranged in the opening, a lifting guide structure and an elastic reset structure are arranged between the corresponding first molding module and the corresponding second molding module, the right end of the second molding module extends out of the opening, and a second molding cavity is formed in the upper end face of the extending portion.

The lifting guide structure comprises a guide groove arranged on the first forming module and a guide block arranged on the second forming module, and the guide groove is matched with the guide block.

The elastic reset structure is a spring, two ends of the spring are respectively connected to the first forming module and the second forming module, and a concave cavity for accommodating the spring after compression is formed in the first forming module or the second forming module.

The beneficial effects of the utility model are that the device of loosing core in two-way order after the improvement, the equidirectional drawing of patterns can be followed in proper order with second forming module to first forming module, realizes the injection moulding of product inner chamber multilateral equidirectional back-off, and simple structure, and the shaping is quick.
