Demolding mechanism of plastic chair mold

Abstract

The invention discloses a demolding mechanism of a plastic chair mold, comprising a mold cavity plate and a core plate, wherein, a chair back cavity insert is arranged in the cavity plate, a chair back core insert is arranged in the core plate, a chair back cavity is formed between the chair back cavity insert and the chair back core insert, a chair leg-chair seat cavity insert is laterally arranged between the cavity plate and the core plate, a chair leg-chair seat cavity is formed between the chair leg-chair seat cavity insert and the cavity plate and between the chair leg-chair seat cavity insert and the core plate, the chair leg-chair seat cavity and the chair back cavity form a plastic chair mold cavity, a shaped plastic chair is arranged in the plastic chair mold cavity, demolding oil cylinders are arranged at the outer wall of the two sides of the chair leg-chair seat cavity insert, piston rods of the demolding oil cylinders are connected with the cavity plate, the end portion of the chair leg-chair seat cavity insert is provided with a top board, the top board is connected with a push rod, the push rod contacts with the plastic chair back by passing through the chair leg-chair seat cavity insert, the bottom of the push rod is connected with a push piston rod of a push oil cylinder, and the push oil cylinder drives the push rod on the top board to push out.

Description

technical field [0001] The invention relates to a demoulding mechanism of a plastic chair mold, which belongs to the field of plastic molds. Background technique [0002] Plastic products are produced by using injection molds, such as plastic chairs used in daily life. Plastic chairs mainly consist of three parts: chair legs, chair seats and chair backs. Therefore, the height of a chair is generally relatively high. If traditional molds are used For production, the plastic chair is set in the mold in the forward direction. When demolding, the ejection height of the plastic chair is high and demoulding is difficult. In particular, the mold opening stroke of the injection molding machine is required to be long, so a large injection molding machine is required for production, and the cost investment is large. Contents of the invention [0003] The object of the present invention is to overcome the disadvantages of the prior art, to provide a plastic chair mold demoulding mec...

Problems solved by technology

[0002] Plastic products are produced by using injection molds, such as plastic chairs used in daily life. Plastic chairs mainly consist of three parts: chair legs, chair seats and chair backs. Therefore, the height of a chair is generally relatively high. If traditional molds are used For production, the plastic chair is set in the mold in a positive direction. When demoulding, the ejection height of the plastic chair is high, and it is difficult to demould

In particular, the mold opening stroke of the injection molding machine is required to be long. Therefore, a large injection molding machine is required for production, and the cost investment is large.
