Abstract
The invention relates to an injection molding process. The injection molding process includes the following steps that firstly, raw materials are prepared and pretreated, wherein a raw material is washed and placed in a drying box to be dried, and after being dried, the raw material is taken out; secondly, the raw material is heated, wherein the raw material is placed in a material barrel of an injection molding machine, and an electromagnetic induction heater is adopted for heating plastic in the injection molding machine; thirdly, an injection molding mold is heated, wherein a fixed mold in the injection molding mold is heated to the temperature from 70 DEG C to 80 DEG C, and a movable mold is heated to the temperature from 75 DEG C to 85 DEG C; fourthly, injection is performed, wherein the plastic heated in the second step in the material barrel is injected in the fixed mold and the movable mold in three stages; fifthly, mold filling and cooling are performed, wherein after the fixed mold and the movable mold are filled with the hot melting raw material, certain pressure is kept till the hot melting raw material is cooled and solidified; and sixthly, a product is taken out, wherein the product is taken out after the raw material is solidified. By the adoption of the injection molding process, the electromagnetic induction technology is adopted for heating, compared with a traditional electric heating wire heating manner, the process is safer, the potential safety hazard of electricity leakage of electric heating wires is avoided, and more energy is saved.
Description
Technical field
The present invention relates to a kind of Shooting Technique, be specifically related to a kind of plastics Shooting Technique.
Background technology
Injection machine has another name called injection (mo(u)lding) machine or injector, it thermoplastic or thermosetting plastics is utilized mould for plastics to make the main former of the plastic products of various shape, be divided into vertical, horizontal, all electric, injection moulding function heating of plastic, high pressure is applied to molten plastic, makes it penetrate and be full of mold cavity.Generally, Shooting Technique refers to a kind of technique like this, first it will prepare the plastic substance needing to carry out being molded, as plastified (plasticising) plastics, then the plastics of plasticate (plasticising) are injected in the die cavity of injection mold, after plastics are hardening, just can obtain the injection moulding module wanted.Shooting Technique of the prior art, particularly resistance electrothermal silk ribbon electricity is adopted to the part of plastic heating, the mica of heat conductivility difference or the magnesia of the moisture absorption is needed to isolate, there is electric leakage potential safety hazard, and in order to safety electric isolation in heating process, adopt mica, heat conductive isolation sheet or thermal conductive ceramic plate to isolate, and the heat conductivility of insulating materials is all undesirable, therefore the thermal efficiency is low, and energy waste is serious.Increasing heat-insulation layer (material) is needed to cause complex process, cost increase in order to energy-conservation.
Because above-mentioned defect, the design people, actively in addition research and innovation, to founding a kind of Shooting Technique of new structure, make it have more value in industry.
Summary of the invention
For solving the problems of the technologies described above, the object of this invention is to provide a kind of Shooting Technique utilizing electromagnetic induction technology to heat raw material.
Technical scheme of the present invention is as follows:
