Efficient injection molding machine

Abstract

The invention provides an efficient injection molding machine. The efficient injection molding machine comprises an injection molding unit and a mold unit. The injection molding unit comprises a fixedframe, a telescopic piece and an injection molding head; and the mold unit comprises a rotary table, a plurality of forming molds and temperature control assemblies. Each forming mold comprises a lower mold and an upper mold, wherein the lower mold is fixedly connected with the rotary table, and the upper mold is movably connected with the lower mold; and each upper mold is provided with an injection molding hole, and each lower mold is provided with an injection molding cavity and a temperature control cavity for preheating and cooling the injection molding cavity. Each temperature control assembly comprises a cool-warm air heating radiator, an air inlet pipe and an air outlet pipe, and the air inlet pipes and the air outlet pipes communicate the cool-warm air heating radiators with thetemperature control cavities. The fixed frame is further provided with a positioning assembly for ensuring the alignment of the injection molding holes and the injection molding head. According to theefficient injection molding machine, the forming molds are arranged on the rotary table, so that the injection molding head can continuously work, and the injection molding efficiency is improved; and the forming molds communicate with the cool-warm air heating radiators correspondingly, hot air or cold air is conveyed into the molds through the cool-warm air heating radiators, so that the multiple forming molds are preheated or cooled at the same time, the forming period is shortened, and the forming efficiency is improved.

Description

technical field [0001] The invention relates to the field of injection molding, in particular to a high-efficiency injection molding machine. Background technique [0002] Injection molding machine is a tool for producing plastic products, and it is also a tool for giving plastic products a complete structure and precise dimensions. Injection molding is to inject heated and melted plastic into the injection mold cavity under high pressure from the injection molding machine, and obtain molded products after cooling and solidification; In the injection molding process, the mold temperature will affect the shrinkage, deformation, fusion line, surface gloss and other appearance quality of the plastic product and the characteristics of the molding cycle; in general molding conditions, the mold must be maintained at At a certain temperature, prevent the molten material from cooling and forming prematurely, causing quality problems such as faults in the materials injected before an...

AI Technical Summary

Problems solved by technology

In the prior art, a single-mold injection molding machine is generally used, which has a long cooling time and low product efficiency. Even if multiple molds are used, multiple molds need to be preheated and cooled separately, which consumes a lot of energy, and multiple molds are formed into a series circuit. When preheating or cooling is performed at the same time, energy is often lost due to a long stroke, and the temperature control efficiency is low
