[0022] Embodiment 1

[0023] See also Figure 1-Figure 5 The utility model provides a technical solution: a tooling fixture for processing injection molded parts, the tooling fixture for processing injection molded parts comprising: a support frame 1, a processing plate 2 is arranged on the surface of the support frame 1, an electric push rod 3 is arranged at the bottom of the support frame 1, a second electric push rod 18 is arranged at the lifting end of the electric push rod 3, and a moving frame 4 is arranged at the lifting end of the second electric push rod 18; a support plate 5, a threaded hole is opened on the surface of the support plate 5, a positioning screw 6 is screwed in the threaded hole, a spring 7 is arranged at one end of the positioning screw 6, a vertical rod 13 is arranged at one end of the spring 7, a bearing 8 is arranged at one end of the vertical rod 13, and a pressing pad 9 is arranged on the surface of the bearing 8;

[0024] When the injection-molded plastic part needs to be further processed, the plastic part is first placed on the processing plate 2, and then the positioning screw 6 can be rotated to allow the pressing pad 9 to press and fix the surface of the plastic part. There are multiple groups of positioning screws 6, so it is convenient to fix some plastics with more shapes in a multi-point positioning manner. The setting of the pressing pad 9 also reduces the pressing and wear problem on the surface of the plastic part, making it convenient to use.

[0025] Embodiment 2

[0026] On the basis of the first embodiment, in order to facilitate the positioning of plastic parts of different lengths, an electric push rod 3 is provided, the electric push rod 3 is fixedly connected to the bottom of the support frame 1, and two groups of electric push rods 3 are provided. The two groups of electric push rods 3 are symmetrically distributed about the center line of the long side of the side of the support frame 1. The mobile frame 4 is fixedly connected to the lifting end of the second electric push rod 18. There are multiple groups of positioning screws 6, and the multiple groups of positioning screws 6 are regularly arranged linearly on the surface of the support plate 5. A through hole 11 is opened on the side of one group of positioning screws 6;

[0027] When in use, the movable frame 4 can be displaced by starting the electric push rod 3, so that the support plate 5 can be moved above the processing plate 2 to facilitate adjustment according to plastic parts of different lengths. Then, the positioning screw 6 can be rotated to use the pressing pad 9 provided under the positioning screw 6 to press and clamp the surface of the plastic part, so as to facilitate subsequent processing.

[0028] Embodiment 3

[0029] On the basis of the second embodiment, in order to facilitate the positioning and clamping of the plastic parts of the pipe fittings, an arc plate 16 is provided, the support plate 5 is fixedly connected to the surface of the mobile frame 4, the surface of the mobile frame 4 is provided with a limiting groove 10, the support plate 5 is a square plate structure, the end face of the positioning screw 6 is provided with a placement groove 12, one end of the spring 7 is fixedly connected to the end face of the placement groove 12, the other end of the spring 7 is fixedly connected to the upper surface of the vertical rod 13, the vertical rod 13 can be displaced up and down in the placement groove 12, a positioning frame 14 can be inserted into the through hole 11, a baffle 15 is sleeved on the surface of the positioning frame 14, an arc plate 16 is provided at one end of the positioning frame 14, a hole is provided on the surface of the positioning frame 14, a pin 17 is inserted into the hole, and one end of the pin 17 can be inserted into the limiting groove 10;

[0030] When it is necessary to clamp a larger tubular plastic part during use, the second electric push rod 18 can be started to move the support plate 5 downward, so that the positioning frame 14 can be moved downward, and the arc plate 16 set at one end of the positioning frame 14 can position and clamp the tubular plastic part. When it is necessary to remove the arc plate 16, the pin 17 can be pulled out to make one end of the pin 17 disengage from the limiting groove 10, so that the positioning frame 14 can be more conveniently pulled out from the through hole 11. The setting of the spring 7 can provide a certain buffering effect on the pressing pad 9 to avoid the problem that the plastic part may be broken when the pressing pad 9 is directly moved downward. The setting of the bearing 8 can prevent the pressing pad 9 from rotating when the positioning screw 6 is rotated.

[0031] In actual use, when the injection-molded plastic parts need to be further processed, the plastic parts are first placed on the processing plate 2, and then the positioning screw 6 can be rotated to make the pressing pad 9 press and fix the surface of the plastic parts. There are multiple groups of positioning screws 6, so it is convenient to fix some plastics with more shapes in a multi-point positioning manner. The setting of the pressing pad 9 also reduces the pressing and wear problem on the surface of the plastic parts, which is convenient for use. This avoids the problem of traditional clamps used in processing plastic parts. Since plastic parts have many shapes and are not easy to be fixed, if the clamping force of the clamp is increased, the extrusion force may also cause the plastic parts to deform and damage the plastic parts.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
