DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0019] See also Figure 1-5 The utility model provides a technical solution: a plastic component processing mold assembly, including a processing table 1 and a mounting vertical plate 2, two mounting vertical plates 2 are provided, and the two mounting vertical plates 2 are respectively fixedly arranged on both sides of the top of the processing table 1, and the two mounting vertical plates 2 are fixedly connected to the opposite sides of the two mounting vertical plates 2. One side of the extended end of the electric telescopic rod 3 is fixedly connected to the mold frame 4, and the top of the mold frame 4 on the right side is connected to the injection pipe 19.

[0020] Furthermore: to facilitate the demoulding of the mold frame 4 and the plastic parts, the two mounting vertical plates 2 are each provided with an internal threaded tube 5 on one side thereof which is rotatable via a bearing, the internal thread of the internal threaded tube 5 is connected with a threaded rod 6, one end of the threaded rod 6 is fixedly connected with a horizontal plate 7, and the front and rear sides of one side of the horizontal plate 7 are each provided with a ejection rod 8 which is rotatable via a bearing, and the front and rear sides of the opposite sides of the two mold frames 4 are each provided with a through groove 9 which is used in conjunction with the ejection rod 8.

[0021] Further: In order to facilitate the stripping of the mold frame 4 and simultaneously link the ejecting rod 8 to break away from the adhesion of the plastic part, a first bevel gear 10 is slidably provided on the surface of the ejecting rod 8, and a limiting mechanism 11 used in conjunction with the ejecting rod 8 is provided inside the first bevel gear 10. The surface of the first bevel gear 10 is rotatably connected to the top of the processing table 1 through a bearing and a bracket. The limiting mechanism 11 includes a sliding block 111. Two sliding blocks 111 are provided, and the two sliding blocks 111 are respectively fixedly arranged on the front and rear sides of the inner cavity of the first bevel gear 10. The front and rear sides of the ejecting rod 8 are provided with sliding grooves 11 that are slidably matched with the sliding blocks 111. 2. A rotating shaft 12 is rotatably provided on both sides of the top of the processing table 1 through a bracket, and a second bevel gear 13 meshing with the first bevel gear 10 is fixedly connected to the front and rear sides of the rotating shaft 12, and a gear 14 is fixedly connected to the surface of the rotating shaft 12, and a tooth plate 15 meshing with the gear 14 is movably provided on one side of the mounting vertical plate 2, and a limiting sleeve 16 is fixedly connected to the opposite sides of the two mounting vertical plates 2, and a limiting rod 17 is slidably connected to the inside of the limiting sleeve 16, and the top of the limiting rod 17 is fixedly connected to the bottom of the tooth plate 15 through a bracket, and a return spring 18 is fixedly connected between the limiting rod 17 and the limiting sleeve 16.

[0022] When in use, the hot plastic is pressurized and injection-molded into the cavity where the two mold frames 4 are combined through the injection molding tube 19. After cooling and molding, the electric telescopic rod 3 is started to reset the extended end of the electric telescopic rod 3. The extended end of the electric telescopic rod 3 is reset and the two mold frames 4 are separated synchronously. Since the plastic part is clamped by multiple ejector rods 8 at this moment, the movement of the mold frame 4 will demould the plastic part. As the mold frame 4 moves, the mold frame 4 will squeeze the tooth plate 15, thereby causing the tooth plate 15 to mesh with the gear 14, causing the rotating shaft 12 to rely on the meshing of the second bevel gear 13 and the first bevel gear 10, and synchronously drive the ejector rod 8 to rotate. The rotation of the ejector rod 8 will pre-disconnect from the plastic part, and then the internal threaded barrel 5 is rotated to cause the threaded rod 6 to retract into the internal threaded barrel 5. The retraction of the threaded rod 6 drives the ejector rod 8 to disengage from the plastic part.
