Problems solved by technology

[0005] 1. Most of the current molds cannot fundamentally solve the problem of flow channel blockage, and can only be unblocked again after the flow channel is blocked, which will not only scrap injection molded parts, increase production costs, but also waste production time and reduce production efficiency
[0006] 2. Most of the current molds cannot eliminate the excess air inside the cavity, resulting in a high rate of waste and defective products

Abstract

The invention discloses a mold capable of preventing blockage of a flow channel. The mold comprises an upper mold base, a lower mold base, the flow channel, a cavity and a heating channel, the lower mold base is arranged below the upper mold base, the cavity is arranged between the upper mold base and the lower mold base, the cavity is divided into an upper cavity and a lower cavity, the upper cavity is arranged in the upper mold base, the lower cavity is arranged in the lower mold base, the flow channel is arranged in the upper mold base, one end of the flow channel penetrates into the cavity, the other end of the flow channel penetrates out of the top of the upper mold base, and the heating channel is arranged on the outer side of the flow channel. The invention further discloses a working method of the mold capable of preventing blockage of the flow channel. Enough heat can be supplied to fluid, and the situation that the fluid is solidified in the flow channel and consequently theflow channel is blocked can be avoided; and meanwhile, air which cannot be exhausted in the cavity is collected through an empty chamber, so that product quality is improved.

Description

technical field [0001] The invention belongs to the field of injection molding equipment, and in particular relates to a mold for preventing blockage of a flow channel and a working method thereof. Background technique [0002] The foreign injection molding machine industry started earlier, mastered advanced injection molding machine related technologies, and has first-mover advantages in large-scale injection molding machines, special injection molding machines and precision injection molding machines. However, after years of development, China's injection molding machine industry has also made major breakthroughs in the development and research of precision injection molding machine control systems, no matter in terms of management level, product variety, technical level, product grade, and high-tech application. are narrowing the gap with developed countries. [0003] As Germany first proposed the national strategy of Industry 4.0 and the Chinese market has continuously ...
