Problems solved by technology
[0003] For general injection molds, manual mold opening is often used. The manual mold opening process is not easy to control. Too fast or too slow mold opening speed will have an adverse effect on the mold. Although machine mold opening can effectively solve the problem of mold opening speed control, but The structure of the control mechanism is often complex, and the cost of mold opening is relatively high

The invention discloses a rotary mold opening buckling claw device of an injection mold. The rotary mold opening buckling claw device of the injection mold comprises an upper mold body, a lower mold body and a mold opening buckling claw device body. The mold opening buckling claw device body comprises a pair of buckling claw units which are symmetrical front and back. Each buckling claw unit comprises a pair of buckling claws which are symmetrical left and right. A rectangular upper driving groove is formed in each of the upper ends of the front end surface and rear end surface of the lower mold body. The upper end, left end and right end of each upper driving groove are not sealed. A lower driving groove is formed in the lower side wall of each upper driving groove. Each buckling claw iscomposed of a pair of cuboids intersecting at an obtuse angle. The corner of each buckling claw is pivoted to the left end and right end of the corresponding upper driving groove. A buckling finger portion is vertically formed at the upper end of each buckling claw. A receding limiting groove matched with the upper portion of each buckling claw is formed in each of the left sides and right sides of the lower portions of the front end surface and rear end surface of the upper mold body. A stroke adjusting air cylinder is vertically fixed to the lower end of each buckling claw. An ejection blockis fixed to a piston rod of each stroke adjusting air cylinder. In the mold opening process, the separation speed of the upper mold body and the lower mold body is low, the forming quality of a workpiece is facilitated, the mold opening stroke is adjustable, and the workpiece is convenient to take.
Description
technical field [0001] The invention relates to the technical field of injection molds, in particular to a rotary mold opening claw device for injection molds. Background technique [0002] Injection mold is a tool for producing plastic products; it is also a tool for giving plastic products complete structure and precise dimensions. Injection molding is a processing method used in the mass production of certain complex-shaped parts. Specifically, it refers to injecting the heated and melted plastic into the mold cavity under high pressure from the injection molding machine, and after cooling and solidifying, a molded product is obtained. [0003] For general injection molds, manual mold opening is often used. The manual mold opening process is not easy to control. Too fast or too slow mold opening speed will have an adverse effect on the mold. Although machine mold opening can effectively solve the problem of mold opening speed control, but The structure of the control me...
