[0003] For example, the utility model with the application number 201720393922.2 discloses a local pressurizing device for an injection mold. The beneficial effect of the utility model is that: the plastic liquid is first injected into the mold by the feeding hammer head, and then the pressure sensor and the temperature sensor are used to detect the pressure of the product in the current mold by the hammer head and the temperature of the product to judge the solidification state of the product. Then, the pressurizing cylinder is started to push the pressurizing rod to pressurize the product, so that the pressurization can be carried out according to the state of each product. The utility model has a simple structure, convenient operation and accurate pressurization.
