Mold capable of adjusting elasticity on line

Abstract

The invention relates to the technical field of mold production and application, in particular to a mold capable of adjusting elasticity online, which comprises a support, a push plate, a fixed mold plate, a mold core and a mold core cover, the push plate is arranged on the support, the fixed mold plate is arranged on the push plate, the mold core is arranged on the support, the mold core cover is arranged in a mold cavity of the push plate and the fixed mold plate, the mold core penetrates through the push plate to be connected with the mold core cover, the interior of the mold core is of a hollow structure, an elastic mechanism is arranged inside the mold core, an adjusting mechanism matched with the elastic mechanism is arranged on the support, a sprue bush is arranged above the fixed mold plate, one end of the elastic mechanism abuts against the adjusting mechanism, and the other end of the elastic mechanism abuts against the interior of a glue inlet of the sprue bush. According to the mold capable of adjusting the elasticity online, the problem of flow lines on the surface of a product is effectively solved, the application range is wide, the effect is stable, and operation is easy.

Description

technical field [0001] The invention relates to the technical field of mold production and application, in particular to a mold capable of adjusting elastic force online. Background technique [0002] With the continuous development of the national economy, people's demand for pipes continues to grow, and plastic pipes have been widely used in various industries due to their excellent performance. In large-scale projects, as the pipe diameter increases, the wall thickness of the products used becomes thicker and thicker, and in some high-temperature and high-pressure application fields, thick-wall products are also required. In the actual production process, in order to improve the pressure bearing capacity of the product, high-density and high-strength raw materials are generally used, but due to their relatively poor flow properties, during the product injection molding process, especially when producing thick-walled pipe fittings, Serious flow marks will be formed on the...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the defects existing in the prior art, the present invention provides a mold that can adjust the elastic force on-line, which effectively solves the problem of flow lines on the product surface, and has a wide range of applications, especially for those products that cannot use large etch lines, and the effect is stable. , easy to operate, according to the differences of different machines, it can be easily solved by fine-tuning the elastic force of the elastic mechanism online, which simplifies the requirements for the production process and reduces the difficulty of production
