One-time forming pressure injection mold for furniture production

Abstract

The invention discloses a one-time forming pressure injection mold for furniture production, and belongs to the field of pressure injection molds. The one-time forming pressure injection mold for furniture production comprises a lower mold plate with a mold seat mounted at the lower end and an upper mold plate with a sprue plate mounted at the upper end. The upper mold plate is located above the lower mold plate. A middle frame is arranged between the upper mold plate and the lower mold plate. A runner is arranged in the middle frame. A plastic raw material guided down from an adding chamber is guided into the runner through the sprue plate and the upper mold plate and is guided into multiple cavities from the runner, and pressure injection forming of multiple plastic products is achievedat a time. Meanwhile, the middle frame is movably connected to the lower mold plate, after pressure injection is completed, the middle frame is lifted up, and the plastic products can be taken easily.In addition, a heating mechanism is arranged at the bottom of the lower mold plate and supplies heat through a heat supply mechanism, and rapid heating and rapid cooling of the mold can be achieved by controlling starting and shutdown of the heat supply mechanism.

Description

technical field [0001] The invention relates to the field of injection molds for furniture, more specifically, to a one-shot injection mold for furniture production. Background technique [0002] With the continuous advancement of science and technology, people's living standards are also constantly improving. There are more and more types of furniture, and the structure is constantly improving to meet people's needs. An important standard of furniture, so in the manufacturing process of furniture, its material, appearance, manufacturing process, service life and other factors are important indicators to consider the grade of furniture. [0003] For some high-end furniture, it is often assembled with each other through various flat pieces, curved pieces, square pieces, round pieces, etc. The combination of such furniture parts includes various tenon structures, metal connectors, Plastic inserts etc. Among them, the plastic inserts are often produced by injection molding in...

AI Technical Summary

Problems solved by technology

However, the processing speed of existing injection molds is relatively slow, and it is not easy to perform injection molding of multiple products at one time, and the production efficiency is low; in addition, existing injection molds are generally equipped with a heating system to melt the plastic raw materials , while the heating and cooling efficiency of the existing heating system needs to be improved
