Intelligent preheating temperature-control auxiliary device of plastic injection molding machine

Abstract

The invention relates to the technical field of plastic injection molding, and discloses an intelligent preheating temperature-control auxiliary device of a plastic injection molding machine. The intelligent preheating temperature-control auxiliary device comprises an injection molding device, an inner screw rod is movably connected with the interior of an inner cavity of the injection molding device, an electric heating plate is arranged in the inner side wall of the injection molding device, and a temperature-measuring assembly is fixedly connected to the outer portion of the injection molding device. A bimetallic strip is movably connected to the interior of the temperature-measuring assembly. Through cooperative use of the electric heating plate, the temperature-measuring assembly, thebimetallic strip, a rotating head, an internal threaded sleeve, an outer sleeve, an ejector rod and an electric contact block, the internal temperature of the injection molding device is kept stable,the temperature of the inner cavity of the injection molding device is effectively prevented from being too low, condensation of plastic raw materials in the inner cavity is thus avoided, and blockage of the injection molding device is effectively avoided. Meanwhile, the injection molding quality is effectively guaranteed, the working efficiency of injection molding work is improved, the device is composed of mechanical assemblies, triggered heating is conducted according to the mechanical operation principle, the fault rate is effectively reduced, and therefore the using effect and the service life of the device are improved.

Description

technical field [0001] The invention relates to the technical field of plastic injection molding, in particular to an intelligent preheating temperature control auxiliary device for a plastic injection molding machine. Background technique [0002] As a modern new material, plastics are widely used due to their excellent performance and low cost. Plastics are polymer compounds made of monomers as raw materials through addition polymerization or polycondensation reactions. During plastic processing, usually Processed by thermal injection molding. [0003] However, when the existing injection molding device is used for injection molding, the temperature of the injection molding pipe often decreases during the injection molding process, which leads to blockage of the injection molding device, affects the quality of the injection molded product, and leads to a decline in the injection molding effect. During the detachment process of the mold base, it is prone to dripping, which...

[0003] However, when the existing injection molding device is used for injection molding, the temperature of the injection molding pipe often decreases during the injection molding process, which leads to blockage of the injection molding device, affects the quality of the injection molded product, and leads to a decline in the injection molding effect. During the detachment process of the mold base, it is prone to dripping, which will pollute the processing equipment, and easily cause the accumulation of raw materials, which will affect the subsequent processing accuracy and increase the difficulty of work
