A kind of injection molding machine and its operation method

Abstract

An injection molding machine and an operation method thereof, the quantitative feeding device can uniformly, regularly and quantitatively supply materials; the sufficient supply of materials effectively improves the injection molding efficiency. The extrusion mechanism has the function of precise material injection, which can save raw materials, improve the service life, and facilitate the connection between the suction pipe and raw materials. The blowing needle mechanism can effectively remove dust and absorb the incoming gas, making the incoming gas more pure and improving the quality of blowing needle shaping, and the mechanism is equipped with seven blowing needle holes, which can simultaneously or more uniformly shape The work is better to blow air, which greatly improves the work efficiency and is convenient to use. The mold clamping mechanism can quickly position the upper and lower molds with high positioning accuracy and can quickly replace the molds. The waterway mechanism can achieve the effect of waterway circulation, and the injection molding is convenient. The injection molding effect is significantly improved through the operation of the staff, and the water storage tank is convenient for water storage and water supply to achieve water circulation.

Description

technical field [0001] The invention relates to the technical field of injection molding machines, in particular to an injection molding machine and an operating method thereof. Background technique [0002] Injection molding machine is a molding equipment that makes thermoplastics or thermosetting plastics into various shapes of plastic products using plastic molding molds. It usually includes a moving mold and a static mold that are set opposite to each other. When performing product injection molding, the dynamic mold and the static mold are required. Mold, and then inject the molten injection plastic into the mold cavity surrounded by the movable mold and the static mold, and form a plastic product after the injection plastic solidifies. When clamping the dynamic mold and the static mold, it is necessary to use a mold monitor to monitor and protect the mold. During this process, a light source needs to be installed on the operation side of the injection molding machine. ...

AI Technical Summary

Problems solved by technology

[0003] However, after analysis, it is found that the injection molding machine needs to consume a large amount of plastic particles during the working process, and it needs frequent feeding during the production process, and the degree of each feeding cannot be accurately quantified, which not only leads to low injection molding efficiency, but also affects the The operation difficulty of workers supplying materials is increased

[0004] After analysis, it is found that the extrusion mechanism has the following deficiencies: the material cannot be injected accurately, resulting in a certain waste; because the material is in a molten state and the temperature is high, it is easy to cause damage to the discharge pipe and the suction pipe; the connection between the suction pipe and the raw material is more complicated.

[0005] After analysis, it is found that the blowing needle mechanism has the following deficiencies: the blowing needle needs to be cooled during the working process. Adhesion with the mouth of the plastic hollow container occurs, which affects the quality of the plastic hollow container, and dust removal is required. The impurities contained in the gas will affect the quality of the blowing needle, and the single-hole blowing needle of the traditional device works, and the work efficiency is very high. Low and not very work-friendly

[0006] After analysis, it is found that the clamping mechanism has the following deficiencies: it cannot quickly locate the upper and lower molds; the positioning accuracy between the upper and lower molds is low; the process of replacing molds is cumbersome

[0007] After analysis, it is found that the waterway mechanism has the following deficiencies: it cannot circulate the waterway, wastes water resources, and cannot achieve the injection molding effect; water supply is not easy to cause injection deformation and seriously damage the mold; the overall structure takes up a lot of space and is not easy to move. Ineffective
