[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] See also Figure 1-4 The utility model provides an embodiment: a plastic mold that is easy to disassemble and replace, including a first mold 2, a second mold 3 is arranged below the first mold 2, and an auxiliary plate 1 is arranged above the first mold 2;

[0024] Also includes:

[0025] A detachable rotating shaft 13 is arranged on the front surface and the rear surface of the second mold 3. The front surface and the rear surface of the second mold 3 are both provided with connecting rods 11, and the detachable rotating shaft 13 is rotatably connected through the connecting rods 11. The front surface and the rear surface of the first mold 2 are both provided with threaded holes 14. The front surface and the rear surface of the first mold 2 are provided with screws 8, and the screws 8 are fixedly connected through the threaded holes 14. When the staff disassembles the plastic mold, they only need to twist the screws 8 out of the threaded holes 14, loosen the screws 8, rotate the connecting rod 11 clockwise, and then remove the limiting rod 9 from the limiting hole 4 to separate the first mold 2 and the second mold 3, and take out the processed model. The operation is simple, which greatly improves the work efficiency at work.

[0026] See also Figure 1 and Figure 2 The first mold 2, the second mold 3 and the auxiliary plate 1 are all provided with limiting holes 4 on their upper surfaces, and limiting rods 9 are provided in the limiting holes 4, and the limiting rods 9 pass through the limiting holes 4 to fix the first mold 2, the second mold 3 and the auxiliary plate 1 in connection. When the staff performs injection molding on the model, the limiting rods 9 are aligned with the limiting holes 4 above the first mold 2, the second mold 3 and the auxiliary plate 1, and then the limiting rods 9 are inserted into the limiting holes 4. By setting a reinforcement component, the stability of the injection mold after assembly is improved, and the success rate of the finished product is greatly improved.

[0027] See also Figure 3 The front and rear surfaces of the second mold 3 are both provided with connecting ropes 15, and the connecting ropes 15 are fixedly connected to the front end of the detachable rotating shaft 13. When a worker enters to disassemble the detachable rotating shaft 13, the connecting ropes 15 fix the detachable rotating shaft 13 to prevent parts from being lost during the disassembly process.

[0028] See also Figure 1A cavity 16 is provided on the lower surface of the first mold 2 and the upper surface of the second mold 3, an injection hole 7 is provided on the upper surface of the first mold 2, an auxiliary nozzle 6 is provided on the auxiliary plate 1, and the auxiliary nozzle 6 is aligned with the injection hole 7 at the lower end. When the staff performs injection molding, the auxiliary nozzle 6 is located above the injection hole 7, and then the raw material is injected into the cavity 16. By setting the auxiliary components, the probability of raw material spilling during the injection molding process can be greatly reduced.

[0029] See also Figure 1 and Figure 2 Handles 5 are provided at both ends of the auxiliary nozzle 6. When the staff disassembles the mold, they only need to hold the handles 5 and lift the auxiliary plate 1 upward, which is easy to operate and solves the problem of slipping during disassembly after processing.

[0030] See also Figure 4 The upper end surface of the limit rod 9 is provided with anti-skid patterns 10. When the staff disassembles the mold, the anti-skid patterns 10 on the upper end of the limit rod 9 increase the friction force when disassembling the limit rod 9, which greatly improves the work efficiency during disassembly.

[0031] See also Figure 2 The outer sides of the first mold 2, the second mold 3 and the auxiliary plate 1 are all provided with a protective coating 12. When the device is used and stored for a long time, it is not easy to be oxidized and corroded because of the protective coating 12.

[0032] Working principle: When we need to perform injection molding, align the positioning rod with the positioning hole, assemble the first mold 2 on the second mold 3, assemble the auxiliary plate 1 on the first mold 2, then insert the limit rod 9 into the limit hole 4, twist the screw 8 into the threaded hole 14, then rotate the connecting rod 11 on the front surface of the second mold 3 counterclockwise, and engage the connecting rod 11 on the front surface of the first mold 2. The screw 8, at this time, the auxiliary nozzle 6 is located directly above the injection hole 7, and then the raw material can be injected into the mold cavity 16 for processing. After the processing is completed, loosen the screw 8, turn the connecting rod 11 clockwise to more than 90 degrees, and then remove the limit rod 9 from the limit hole 4 to complete the disassembly.
