[0002] Injection molds are the main tools used to mold plastic products. They can mass-produce plastic products of exactly the same shape and size more quickly and efficiently. For many products, injection molds are important tools necessary for them to produce various plastic products, such as plastic parts on cars, medical products, industrial electronic products, etc. The plastic products they produce using injection molds have the advantages of light weight, high strength, good toughness, corrosion resistance, good insulation, easy coloring, easy molding, low cost, etc., and therefore have been favored by all walks of life.

[0003] According to a disclosed injection mold with automatic demoulding (publication number: CN214137132U), in the above application, a mold shell is provided, and a motor is used to drive the rotation of the rotating shaft and the gear, in conjunction with a push rod, a first rotating block, a rotating rod, a second rotating block, a fixed block, a transmission rack, a support rod and a sliding rod sleeve, so as to achieve simultaneous demoulding with equal force on both sides, which not only avoids direct contact with the hands of the staff, but also avoids damage to the workpiece due to uneven force during the demoulding process.

[0004] However, in actual use of the above-mentioned equipment, the motor drives the rotating shaft to cooperate with the gear to separate the mold shell for automatic demolding, but the molding time of the injection molded part in the mold shell is constant, and the mold shell cannot be used to accelerate the molding of the injection molded part, which increases the molding time of the injection molded part and reduces the demolding efficiency.
