Description

TECHNICAL FIELD

[0001] The present application relates to the field of molds, and particularly relates to a bend mold. BACKGROUND

[0002] The bend mold is a key tool for producing and processing pipes or tubes with specific angles and shapes, and is mainly used for producing plastic pipes or tubes through hot plastic forming, and is widely used in various bend production occasions.

The segmented bend molds are located at both ends of the mold body. The mold can facilitate demolding, improve production efficiency, and enable the product to be integrally formed. The mold is lighter in weight and is convenient to carry and assemble. However, the bend mold has a fixed size, and thus can only be used to produce a single type of bend product, which reduces the production diversity. When the bend mold needs to be replaced, it needs to be repeatedly positioned and installed, which is inconvenient for the production and use of different types of bend products. Moreover, the joint cavity of the bend product is integrated with the cavity of the mold as a whole, and the joint part of the bend product has diversity. The fixed structure of the bend mold cannot replace the joint cavity, and is not suitable for use with different types of bend products. SUMMARY
