[0002] In the prior art, such as Figure 1 The lifting camera housing shown is installed on the lens of the mobile phone camera to cover and protect the lens. The housing is made of plastic material, usually formed by injection molding using an injection mold. The housing includes a frame body and a mounting plate located at one end of the frame body. The frame body is a rectangular parallelepiped frame structure as a whole, and the mounting plate is a rectangular parallelepiped plate structure. The mounting plate and the frame body are integrally formed by injection molding using an injection mold. The thickness of the frame body is greater than that of the mounting plate. One end face of the frame body and the mounting plate are integrally formed with a step transition design; the two side faces of the frame body in its own width direction are arc surfaces, and the design is more textured.

[0003] However, since most of the existing molds are produced by injection molding in the way that the product is opened from top to bottom, the movable mold core and the fixed mold core are separated from each other, and the molded parting surface corresponds to the center surface in the thickness direction of the frame body, it is easy to cause parting lines on the curved surfaces on both sides of the product frame body. The parting lines affect the appearance of the product and easily cause the product appearance to not meet customer requirements. Summary of the invention

[0004] In view of the deficiencies in the prior art, one of the purposes of the present invention is to provide an injection mold for a lifting camera, change the parting surface of injection molding, thereby achieving a better injection molding effect and making the appearance of the product more in line with customer requirements.
