Non-leg plastic chair injection mold with sliding block loose-core mechanism

Abstract

The invention belongs to the field of injection molds, and relates to a non-leg plastic chair injection mold with a sliding block loose-core mechanism. The technical problems that in the prior art, chair leg inserting holes are poor in suction synchronism and deformation is prone to occur on a no-leg chair are solved by the chair injection mold. The chair injection mold comprises a movable template, a fixed template and a movable mold base plate, two chair leg inserting hole core pulling structures are arranged below the movable template, and first oil distribution plates and second oil distribution plates are arranged on the two chair leg inserting hole core pulling structures, a first oil distribution channel and a second oil distribution channel are formed in the first oil distributionplates, a third oil distribution channel and a fourth oil distribution channel are arranged on the second oil distribution plate, the first oil distribution channel is connected with the third oil distribution channel, and the second oil distribution channel is connected with the fourth oil distribution channel. Compared with the prior art, the non-leg plastic chair injection mold with the slidingblock loose-core mechanism has the advantages that loose cores of the chair leg inserting hole are synchronic, chair leg inserting holes are not prone to be deformed.

Description

technical field [0001] The invention belongs to the field of injection molds, and relates to an injection mold for a legless plastic chair with a slider core-pulling mechanism. Background technique [0002] The plastic chair has the characteristics of high production efficiency and low cost, and the appearance of the plastic chair is beautiful and changeable, the color is bright and bright, and it adapts to the high-paced modern life. It is a widely accepted and applied plastic product. Limited by the size of the mold and in order to enhance the strength of the plastic chair, the plastic chair is usually designed as a legless chair, and the chair legs or metal chair legs with complex reinforcement structures are mated to achieve the purpose of enhancing the strength of the plastic chair. The legless plastic chair is designed with multiple chair leg insertion holes. [0003] However, when the plastic chair is cooled and removed from the mold, since the core-pulling mechanism...

AI Technical Summary

Problems solved by technology

[0003] However, when the plastic chair is cooled and removed from the mold, since the core-pulling mechanism cannot pull the core simultaneously, the force on the chair surface is uneven, and the torsion force causes deformation or even rupture, resulting in the precision of the socket leg sockets not meeting the socket requirements, and even the entire chair without Damaged leg chair product
