The top plate is sleeved on the outer wall of a plurality of support rods and can move along the axial direction of the support rods, and is located between the base and the base. The lifting seat is inserted into a groove on the upper surface of the base. The top plate is connected to the lifting seat through a plurality of top rods.

[0007] The slider pin is inserted into the front side of the lifting seat;

[0008] A sleeve is coaxially fitted onto the end of the slider needle;

[0009] The joint between the slider pin and the sleeve is configured as an insert molding area, and the insert molding area is injection molded to form a sleeve insert that covers the joint.

[0010] The insert injection molding device provided in this embodiment of the utility model facilitates insert installation and demolding on the molding machine. It has sufficient structural rigidity and is easy to demold.

[0011] Furthermore, it also includes a reset assembly disposed between the base and the top plate.

[0012] Furthermore, the reset assembly includes a guide rod, one end of which is fixedly connected to the top plate, and the other end of which is slidably connected to the base. A spring is sleeved on the outer wall of the guide rod.

[0013] Furthermore, when the lifting assembly is in the raised state, the sleeve is placed on the slider pin; when the lifting assembly is in the lowered state, injection molding is performed on the connection between the slider pin and the sleeve to form a sleeve insert.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] In this disclosure, unless otherwise stated, directional terms such as "axial," "circumferential," and "radial" generally refer to those defined relative to the axis of rotation of the rotor in the drive motor, and "inner" and "outer" refer to the inner and outer contours of the corresponding components. The terms "first," "second," etc., are used to distinguish different components and do not imply sequentiality or importance. Furthermore, in the following description, when referring to the accompanying drawings, unless otherwise explained, the same reference numerals in different drawings denote the same or similar elements.

[0023] This utility model embodiment provides an insert injection molding device that facilitates insert installation. Please refer to [link to relevant documentation]. Figure 1 and Figure 4 The frame assembly consists of a base 1 and a base 2 arranged in parallel and spaced apart vertically. The four corners of the bottom surface of the base 1 are fixedly connected to the base 2 by multiple support rods 3.
