Description

Rotational molding die embedded part fixing device

Technical Field

The application relates to the field of auxiliary devices for rotational molding dies, in particular to a rotational molding die embedded part fixing device.

Background

The rotational moulding is a hollow shaping method of thermoplastic plastics, firstly, powder or paste or monomer material is injected into mould, and through heating the mould and biaxial rolling rotation, the material is uniformly distributed in the cavity of the mould by means of self-gravity action and melted, after cooling, the material is demoulded to obtain the hollow product. After some products are formed, other accessories are required to be installed on the surfaces of the products, and nuts are required to be embedded in corresponding positions of the products in the production process, so that the accessories can be installed conveniently.

In the related art, an embedded part fixing device in manufacturing an insulation can, as shown in fig. 1, comprises a mounting part 01, a spring 02, a guide tube 03, a hand push rod 04 and a handle 05 fixed on the hand push rod 04. The mounting part 01 is a cylindrical sleeve, and threads are arranged on the outer side wall of the mounting part 01; the guide tube 03 is coaxially fixed at one end of the mounting part 01, and the hand push rod 04 is coaxially inserted into the mounting part 01 and the guide tube 03 in a sliding way; the spring 02 is coaxially sleeved on the hand push rod 04, and the spring 02 is positioned in the guide tube 03; an annular bulge is integrally arranged in the middle of the hand push rod 04 and is abutted to one end of the spring 02 far away from the mounting part 01; an elastic positioning portion 06 is provided at one end of the push rod 04 away from the handle 05.

The position corresponding to the embedded part on the die is provided with a threaded hole, when the die is used, the mounting plate is screwed and fixed at the threaded hole on the die, then the hand push rod 04 is pressed to enable the positioning part 06 to penetrate out of the mounting part 01, the embedded part is sleeved on the positioning part 06, the embedded part is clamped and fixed through the elasticity of the positioning part 06, finally the hand push rod 04 is loosened, and the spring 02 tightens and attaches the embedded part on the inner wall of the die. After the die is formed, the hand push rod 04 is pulled out by force, so that the positioning part 06 is separated from the embedded part, and the embedded part is detached.

In practical use, it is found that the mold needs to be turned over continuously during rotational molding, and when the mold is turned over, the hand push rod 04 and the handle 05 generate outward centrifugal force. When the embedded part fixing device is used, the embedded part can be fixed only by maintaining balance between the friction force between the positioning part 06 and the embedded part and the elastic force of the spring 02, and the positioning part 06 can be separated from the embedded part due to the centrifugal force generated by the hand push rod 04 and the handle 05 in the process of overturning the die, so that the embedded part cannot be fixed in the product forming process, and the product is unqualified.
