[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example: See Figures 1 to 7 According to an embodiment of the present invention, a mold frame for plastic mold processing is provided, which includes a first bracket 1 and two second brackets 2. The first ends of the two second brackets 2 are hinged to the two ends of the first bracket 1 through a hinge shaft 5, and the second ends of the two second brackets 2 are detachably fixedly connected by a connecting member 3. When the second ends of the two second brackets 2 are connected to each other, a triangular frame structure is formed between the first bracket 1. The first bracket 1 and the second bracket 2 are elastically connected to a contact plate 11 through an elastic element 4 on one side facing the inner side of the triangular frame.

[0026] The mold frame for plastic mold processing employs a triangular frame structure consisting of a first bracket 1 and two second brackets 2, ensuring stability and improving overall mold processing efficiency. Furthermore, the mold frame connects the second brackets 2 to the first bracket 1 via a hinged shaft 5, and the second ends of the two second brackets 2 are removably fixedly connected via a connector 3, facilitating assembly and disassembly of the frame.

[0027] In this exemplary embodiment, the connecting member 3 includes a connecting shaft 30 elastically connected to two clamping sleeves 31 at both ends of the connecting shaft 30 via a first spring 32. The second ends of the two second brackets 2 are provided with a clamping hole 6 for inserting the connecting shaft 30 and a limiting groove 7 for inserting the clamping sleeve 31. When the second ends of the two second brackets 2 are connected, after the second ends of the two second brackets 2 are affixed together, the user grasps the two clamping sleeves 31 with both hands and applies force in opposite directions, causing the two clamping sleeves 31 to move away from each other and compress the first spring 32. Then, the connecting shaft 30 is inserted into the clamping hole 6. After the connecting shaft 30 is fully inserted, the two clamping sleeves 31 are released. The clamping sleeves 31 are then inserted into the clamping hole 6 under the elastic force of the first spring 32. In this way, the second ends of the two second brackets 2 are tightly connected together. After such connection, the two second brackets 2 are equivalent to forming an elastic connection via the first spring 32. During the plastic mold processing process, the first spring 32 acts as a buffer, thereby protecting the mold as a whole.

[0028] In this exemplary embodiment, the clamping sleeve 31 is cylindrical, and the end of the clamping sleeve 31 that inserts into the retaining groove 7 is conical, while the retaining groove 7 is a circular groove. This arrangement makes it easier for the clamping sleeve 31 to be inserted into the retaining groove 7. After insertion, the clamping sleeve 31 is less likely to wobble in the retaining groove 7, thereby improving the stability of the connection between the second ends of the two second brackets 2.

[0029] In order to further improve the stability of the second ends of the two second brackets 2 when connected, in this exemplary embodiment, the second ends of the two second brackets 2 are magnetically fixed together by a magnetic structure 8. Before using the connecting member 3 to connect, the second ends of the two second brackets 2 can be magnetically fixed together by the magnetic structure 8. In this way, after freeing your hands, you can use the connecting member 3 to further strengthen the connection between the second ends of the two second brackets 2, which provides convenience for the connection between the second ends of the two second brackets 2. The magnetic structure 8 includes a first magnet 80 and a second magnet 81. The first magnet 80 and the second magnet 81 are both trapezoidal block structures. The first magnet 80 and the second magnet 81 are respectively fixed to the second ends of the two second brackets 2 in an embedded manner; specifically, the second end of the second bracket 2 is provided with a mounting groove 10 that is compatible with the shape of the two magnets. The first magnet 80 and the second magnet 81 are both glued into the mounting groove 10. This can improve the stability of the connection between the magnet and the second bracket 2 and prevent it from falling off.

[0030] In this exemplary embodiment, elastic element 4 includes a positioning post 40 and a second spring 41. Positioning holes 9 are provided on both first and second brackets 1 and 2, respectively, to engage with positioning post 40. Second spring 41 is provided on positioning post 40 located between first bracket 1 and contact plate 11 connected thereto, and between second bracket 2 and contact plate 11 connected thereto. This arrangement allows second spring 41 to provide a cushioning effect for the mold frame, while the engagement of positioning post 40 with positioning hole 9 provides guidance and support for the movement of contact plate 11, enhancing the cushioning effect.

[0031] In this exemplary embodiment, the second ends of the two second brackets 2 are each provided with a force-applying flange 12. When the second ends of the two second brackets 2 are connected to each other, a force-applying notch 13 is formed between the two force-applying flanges 12. With this arrangement, to release the second ends of the two second brackets 2, the connector 3 can be removed first. At this point, the second ends of the two second brackets 2 are only secured together by the magnetic structure 8. The user can then grasp the force-applying flanges 12 on the second ends of the two second brackets 2 with both hands and apply force in opposite directions to pry the second ends of the two second brackets 2 apart, thereby quickly completing the disassembly of the mold frame.

[0032] In this exemplary embodiment, an anti-skid pad 14 is provided on the force-applying flange 12 within the force-applying notch 13, and anti-skid grooves are provided on the outer side of the anti-skid pad 14. The provision of the anti-skid pad 14 and the anti-skid grooves can prevent the user from slipping when applying force to the force-applying flange 12.

[0033] Working principle: First, the second ends of the two brackets are in a separated state, then, the plastic mold is placed on the first bracket 1, and then, the second ends of the two second brackets 2 are magnetically fixed together through the magnetic structure 8. After the second ends of the two second brackets 2 are fitted together, the user holds the two clamping sleeves 31 with both hands and applies force in opposite directions, so that the two clamping sleeves 31 move away from each other and compress the first spring 32. Then, the connecting shaft 30 is embedded in the clamping hole 6. After the connecting shaft 30 is fully embedded, the two clamping sleeves 31 are loosened, and the clamping sleeve 31 is embedded in the clamping hole 6 under the elastic force of the first spring 32. In this way, the second ends of the two second brackets 2 are tightly connected together. After such connection, the two second brackets 2 are equivalent to forming an elastic connection through the first spring 32. During the plastic mold processing process, the first spring 32 plays a buffering role, thereby protecting the mold as a whole. By adopting a triangular frame structure composed of the first bracket 1 and the two second brackets 2, the stability of the mold frame is ensured and the overall efficiency of mold processing is improved. In addition, the mold frame connects the second bracket 2 to the first bracket 1 through the hinge shaft 5, and the second ends of the two second brackets 2 are detachably fixedly connected through the connecting piece 3, which facilitates the assembly and disassembly of the frame.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
