[0002] In the injection molding production process, the movable mold slider is one of the key components of the injection mold, and the structural design directly affects the forming quality, production efficiency and service life of the injection product. The traditional movable mold slider has many problems in the use process. For example, the positioning of part of the slider is not accurate, which makes it difficult to ensure the dimensional accuracy of the injection product; some sliders are prone to cause defects such as pulling and deformation of the product during demolding due to unreasonable design; moreover, when facing some complex shaped plastic products, the structure of the traditional slider cannot meet the molding demand. With the wide application of plastic products in various fields, the performance requirements of the movable mold slider of the injection mold are also getting higher and higher, therefore, it has important practical significance to develop a new type of movable mold slider. SUMMARY

[0003] The utility model aims at providing a slider of movable mould which is applied to the injection molding process of plastic products and can effectively improve the quality and production efficiency of the injection product.

[0004] To achieve the above technical scheme, the technical scheme of the utility model is as follows: a slider of movable mould mainly consists of a body and a treatment detail. The body is the main support structure of the slider, and the treatment detail is responsible for direct contact with the injection product and auxiliary molding. Through the structural optimization of the body and the treatment detail, the slider can better meet the needs of injection molding production.

[0005] Further, the treatment detail is L-shaped and extends outward along one side of the body in the width direction, providing a stable installation basis for the treatment detail. The top of the body is inclined, which helps to guide the movement during the injection molding process, makes the enclosed mold cavity more accurate, reduces the stress concentration inside the injection product, and improves the product quality.

[0006] One side of the body is symmetrically provided with a threaded counterbore, which facilitates the connection and fixation with other components of the movable mold, ensures the stability of the slider during the injection molding process, and avoids displacement affecting the injection precision.

These positioning grooves can cooperate with the positioning protrusions on the movable mold, further improve the positioning accuracy of the slider in the movable mold, and ensure the dimensional accuracy of the injection product. At the same time, the design of the concave positioning grooves is also conducive to the installation and disassembly of the mold, improving the production efficiency.

[0014] A forming groove is provided below the surrounding cavity positioning shoulder, which is used to shape the specific shape of the injection molded product to ensure the forming precision of the product.

[0015] A forming shoulder is provided between adjacent surrounding cavity positioning shoulders and forming grooves, which deforms and moves in a specific direction under the action of an electric field during demolding. This design can effectively solve the demolding problem of some complex-shaped products, avoid damage to the product during demolding, and improve the yield of the product.

[0016] A deformation part is embedded on the forming shoulder, which includes a first deformation layer adhered on one side, an insulating layer, and a second deformation layer. The first deformation layer and the second deformation layer are both made of U-shaped piezoelectric ceramics which deform along the width direction. When an electric field acts on the deformation part, the U-shaped piezoelectric ceramics deform, driving the forming shoulder to move and realize the demolding action.
