Problems solved by technology
[0004] Products made of foamed materials are generally molded by injection molding. During product injection molding, a large number of fine foams will appear in the foamed material, which increases the overall volume. The volume of the cavity is fixed, which cannot meet the requirements of foam material molding
[0005] Therefore, it is necessary to design a system that can still open the mold again after the mold is closed, but the precision control of the mold opening in the prior art is poor, and the mold opening effect is not ideal, which is not conducive to the production of products

Embodiment Construction
[0032] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.
[0033] Such as figure 1 As shown, the micro-opening system of the injection molding machine includes:
[0034] Oil tank 10, used for storing oil;
[0035] The oil inlet passage 20 communicates with the oil tank 10 and is used to transport oil;
[0036] The clamping oil cylinder 30 is arranged in multiples and each clamping oil cylinder 30 is connected with the oil inlet oil circuit 20 and the fuel tank 10 respectively;
[0037] The micro-opening unit corresponds to the clamping cylinder 30 one by one, and the micro-opening unit communicates with the oil inlet circuit 20 and drives the corresponding clamping cylinder 30 to perform micro-opening.
[0038] When products made of foamed materials are subjected to product inj...

The invention provides an injection molding machine micro mould opening system and belongs to the technical field of hydraulic transmission, aiming at solving the problem of the existing injection molding machines that a mould opening effect is non-ideal. The injection molding machine micro mould opening system comprises an oil tank used for storing oil, an oil inlet line communicating with the oil tank and used for delivering oil, multiple mould locking oil cylinders which respectively communicate with the oil inlet line and the oil tank, and micro opening units in one-to-one correspondence with the mould locking oil cylinders, wherein the micro opening units communicate with the oil inlet line and drive the corresponding mould locking oil cylinders to carry out micro mould opening. The injection molding machine micro mould system and the oil way control method have the advantages of being reasonable in design and high in mould opening precision.
Description
technical field [0001] The invention belongs to the technical field of hydraulic transmission, and relates to a micro-opening system of an injection molding machine and an oil circuit control method thereof. Background technique [0002] Foaming material, also known as foaming agent, refers to a substance that can gasify inside a substance to generate bubbles to make it a porous substance, such as making foam plastics, foam rubber, foam resin, foaming food, etc., foam materials can be It is divided into three categories: chemical foaming materials, physical foaming materials and surfactants. [0003] Foam materials have the properties of low density, light weight, and high strength. In addition, they can also be used for cushioning, shock absorption, and heat preservation. They are widely used in electronics, rail transit, aerospace, and building energy-saving industries. [0004] Products made of foamed materials are generally molded by injection molding. During product in...
