[0003] A core is provided on the plastic mold, and the core is generally installed by multiple screws. When replacing the core, the staff needs to replace the core by disassembling and installing multiple screws. It takes a lot of time to disassemble and install multiple screws to replace the core, which will increase the downtime of the production line. In a production environment, time is usually a key factor, so the inconvenient core replacement method may reduce production efficiency. In addition, multiple disassembly and installation may cause wear of the screws and threaded parts, affecting their service life, which may lead to more frequent maintenance and replacement of screws, increasing equipment maintenance costs.

[0020] 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.

[0021] Reference Figure 1-3 A plastic mold for easy replacement of components includes a template 1, a detachable core 2 is provided on the template 1, a mounting groove 3 is opened on the template 1, a mounting block 4 is fixed on the core 2, a groove 5 is opened on the side of the template 1, and the groove 5 is connected to the mounting groove 3.

[0022] An installation component is provided in the installation groove 3, and the installation component includes a threaded rod 61, two moving blocks 62, two clamping blocks 63 and two clamping grooves 64. The threaded rod 61 is rotatably assembled inside the installation groove 3. The threaded rod 61 is provided with two sections of threads with the same length and opposite directions. The two moving blocks 62 are respectively threadedly sleeved on the two sections of threads. The two clamping blocks 63 are respectively fixed on the sides of the two moving blocks 62. The groove wall of the installation groove 3 and the side surface of the moving block 62 fit together. The two clamping grooves 64 are both opened on the side surface of the installation block 4. The shape of the clamping block 63 and the clamping groove 64 are adapted. When the clamping block 63 is inserted into the clamping groove 64, the side surface of the clamping block 63 and the groove wall of the clamping groove 64 fit together, so that the connection stability between the core 2 and the template 1 can be ensured.

[0023] The slot 5 is provided with a driving assembly, which includes a rotating rod 71, a worm gear 72 and a worm 73. One end of the rotating rod 71 is fixedly connected to the threaded rod 61, and the other end of the rotating rod 71 is rotatably assembled on the slot wall of the slot 5. The worm gear 72 is fixedly sleeved on the rotating rod 71, and the worm gear 73 is rotatably assembled on the slot wall of the slot 5, and the worm gear 72 and the worm gear 73 are meshed with each other. One end of the worm gear 73 is installed with a knob 8, which is convenient for the staff to rotate the worm gear 73. When the worm gear 73 rotates, the worm gear 72 can be driven to rotate, which makes the rotating rod 71 rotate, and when the rotating rod 71 rotates, the threaded rod 71 can be driven to rotate. Since the threaded rod 61 is provided with two sections of threads of the same length and in opposite directions, the two moving blocks 62 are respectively threadedly sleeved on the two sections of threads, and the slot wall of the mounting slot 3 and the side of the moving block 62 fit each other, so when the threaded rod 61 rotates, the two moving blocks 62 can be driven to move away from each other, which makes the two clamping blocks 63 move away from each other.

[0024] The specific working principle of the utility model is as follows:

[0025] When the mold core 2 needs to be replaced, the staff first turns the knob 8 to rotate the worm 73. When the worm 73 rotates, it can drive the worm wheel 72 to rotate, which makes the rotating rod 71 rotate. When the rotating rod 71 rotates, it can drive the threaded rod 71 to rotate. Since the threaded rod 61 is provided with two sections of threads of the same length and in opposite directions, the two moving blocks 62 are respectively threadedly sleeved on the two sections of threads, and the groove wall of the mounting groove 3 and the side of the moving block 62 fit each other, so when the threaded rod 61 rotates, the two moving blocks 62 can be driven away from each other. , which makes the two blocks 63 move away from each other until the two blocks 63 are disengaged from the two slots 64. Without the restriction of the two blocks 63, the mounting block 4 can be disengaged from the mounting slot 3, thereby realizing the disassembly of the mold core 2. When installing the mold core 2, the staff inserts the mounting block 4 into the mounting slot 3 and rotates the knob 8 in the reverse direction so that the two blocks 63 are respectively inserted into the two slots 64, thereby realizing the rapid installation of the mold core 2. In summary, the staff only needs to rotate the knob 8 to realize the rapid disassembly and assembly of the mold core 2.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
