Injection molding machine

Abstract

The invention discloses an injection molding machine, and belongs to the technical field of injection molding equipment. The injection molding machine comprises a drying box, an injection molding pipe and a threaded pipe, wherein the lower end of the drying box is connected with the injection molding pipe, and the threaded pipe is arranged in the injection molding pipe; a feeding hopper is arranged at the upper end of the drying box; and a round hole is formed in the upper end of the drying box. According to the injection molding machine, wet plastic raw materials in a discharging box can be preliminarily dried through a heating fan, and meanwhile, the dried plastic raw materials in a drying roller are blown to the outside, so that heated air can penetrate into the plastic raw materials more easily and make more sufficient and uniform contact with the plastic raw materials needing to be dried; and the plastic raw materials in the drying roller are not prone to accumulation through a self-pushing mechanism, so that the plastic raw materials which are dried faster do not need to leave the drying box after the raw materials which are dried slowly are dried, the overall drying efficiency is improved, the effect of the plastic raw materials on the surface is better, and the percent of pass of plastic products during injection molding can be greatly improved.

Description

technical field [0001] The present invention relates to the technical field of injection molding equipment, and more specifically, relates to an injection molding machine. Background technique [0002] Injection molding machine, also known as injection molding machine or injection machine, is the main molding equipment for making thermoplastics or thermosetting plastics into various shapes of plastic products with plastic molding molds. It is divided into vertical, horizontal, and all-electric types. The injection molding function Heat the plastic, apply high pressure to the molten plastic, and make it inject and fill the mold cavity. Injection molding machine is also called injection molding machine or injection machine. Many factories are called beer machine, and injection molding products are called beer parts. Plastic molding molds are the main molding equipment for making plastic products of various shapes. Injection molding machines can be divided into vertical, horizo...

AI Technical Summary

Problems solved by technology

[0003] When the injection molding machine is performing injection molding work, if the surface of the plastic raw material contains a lot of water vapor, air bubbles may appear during the injection molding of the plastic product, resulting in a product that is unqualified. Since the existing injection molding machine usually does not have a device for removing air bubbles, if using With the existing drying equipment, when all the plastic raw materials are piled up together, some of the plastic raw materials that dry faster need to wait for the slow drying plastic raw materials to be dried and then taken out of the drying box together, which leads to the batch of plastic raw materials The drying efficiency is not high. After drying, it is necessary to pour the dried plastic raw materials from the drying equipment into the discharge box. The work efficiency is even lower. If the plastic raw materials cannot fully volatilize the water vapor on the surface before they are added to the injection pipe , it will greatly reduce the qualified rate of plastic product injection molding
