[0015] The utility model is described in detail below in conjunction with the accompanying drawings. Figure 1 As shown, the injection molded part pressing and fixing device includes a base 1, cavities 5 are opened on both sides of the interior of the base 1, and limiting grooves 6 are opened on the left and right sides of the upper part of the base 1. Each pair of limiting grooves 6 arranged opposite to each other up and down are connected to the cavity 5. A double-headed screw 2 is installed on the internal bearing of the base 1, and a motor 3 is fixedly installed on one side of the base 1. The output shaft of the motor 3 is connected to the double-headed screw 2 by a coupling. Slide blocks 4 are installed at both ends of the double-headed screw 2 through ball nuts. The slide blocks 4 are slidably connected to the limiting grooves 6. The two slide blocks 4 are respectively slidably set in the two cavities 5. A fixing component 7 is installed on the upper part of each slide block 4, and the two fixing component assemblies 7 are arranged opposite to each other.

[0016] In this embodiment, combined with the Figure 2 As shown, the fixing member assembly 7 includes a Z-shaped member 71, a pressing block 72 is detachably installed at the lower part of the upper horizontal section of the Z-shaped member 71, and ribs 73 are integrally arranged on the front and rear sides of the outer side of the vertical section of the Z-shaped member 71.
