Description

Technical Field

[0001] The utility model relates to the technical field of self-adaptive rear molds, in particular to a precise self-adaptive rear mold device. Background Art

[0002] The front mold and the back mold are two basic components of the injection mold. Together, they complete the molding process of plastic products. The specific definitions of the front mold and the back mold are as follows: the front mold usually refers to the moving plate in the mold that contacts the fixed plate of the injection molding machine, also known as the movable mold or injection mold. Its main function is to receive the molten plastic ejected by the injection molding machine and shape and cool it. The back mold refers to the fixed plate connected to the mechanical base device, also known as the fixed mold, ejector mold or mother mold. Its main function is to take out or eject the shaped plastic product from the mold (by pushing the internal ejector pin of the back mold through the external mechanical base device to push the plastic product out). It is designed with the external structure of the product, such as complex products such as special-shaped structures;

[0003] In traditional molds, the rear mold is mostly fixed. In actual use, once the shape of the mold changes (special-shaped structures such as textures on the outer surface of the plastic product), the rear mold will not be able to adapt to production needs and needs to be replaced manually in time. The installation and disassembly of the rear mold is time-consuming, which leads to reduced production efficiency. Therefore, we propose a precision adaptive rear mold device. Utility Model Content

A hydraulic cylinder 105 with its output end facing the back is arranged at the top and on the back side of the fixed seat 101. The hydraulic cylinder 105 is electrically connected to an external controller, so that the controller can control the hydraulic cylinder 105 to reinforce the replacement mechanism 2. A circular groove 106 is provided on the front side of the first bracket 102 near the top and through the back side, and a groove 107 is provided on the front side of the second bracket 103 corresponding to the circular groove 106; the replacement mechanism 2 includes a disc 201, a connecting rod 202 is provided on the front side of the disc 201 near the center, a fixed block 203 is provided on the periphery of the disc 201 corresponding to the rear mold body 3, and a fixed groove 204 is provided on the front side of the fixed block 203 near the outside.

[0031] Example 2

[0032] like Figure 1-3As shown, the fixing seat 101, the first bracket 102 and the second bracket 103 are all fixed to the base 1 by bolts. By fixing the fixing seat 101, the first bracket 102 and the second bracket 103 with the bolts of the base 1, the fixing seat 101, the first bracket 102 and the second bracket 103 can be made more firm and the use stability is improved. The motor 104 is fixedly connected to the fixing seat 101, and the output end of the motor 104 is fixedly connected to the connecting rod 202. The rotation of the motor 104 can make the connecting rod 202 drive the disc 201 to rotate, thereby completing the replacement of different rear mold bodies 3. The hydraulic cylinder 105 is fixedly connected to the base 1, and the output end of the hydraulic cylinder 105 is adapted to the fixed groove 204.
