[0027] See also Figure 1-5A mold forming device for automatic pressing and automatic feeding of polymer materials includes a pressing mechanism 3, which includes a pressing block 31. The pressing block 31 is used for automatic pressing and forming. A push plate 32 is clamped on the top of the pressing block 31. The movement of the push plate 32 drives the pressing block 31 to move synchronously. A special-shaped disk 33 is rotatably connected to the top of the push plate 32. The special-shaped disk 33 is set to form two arcs with different radii.

When the limit rod 34 moves downward, it will drive the push block 36 to move synchronously to the right. The interior of the hydraulic box 35 is clamped with a push block 36, and a connecting plate 37 is welded to the right side of the push block 36. An insulating rod 38 is welded above the connecting plate 37. The surface of the insulating rod 38 is wound with a resistance wire, and a sliding piece is provided on the surface of the connecting plate 37, and the sliding piece is provided on the surface of the resistance wire. The movement of the connecting plate 37 is used to drive the sliding piece to move along the resistance wire, thereby changing the number of resistance wires connected to the circuit, and finally turning on the power supply.

[0028] The control mechanism 4 also includes a ratchet plate 41, a positioning rib 42 is clamped at the bottom of the ratchet plate 41, a push rod 43 is sleeved on the outer surface of the positioning rib 42, a fixed magnet 44 is clamped at the right side of the push rod 43, a spring is arranged between the fixed magnet 44 and the electromagnet 45, and the magnetism generated by the electromagnet 45 after being energized is opposite to that of the fixed magnet 44. When energized, opposite charges attract each other, so the fixed magnet 44 is driven to move to the right, thereby driving the push rod 43 to move to the right synchronously, and finally the positioning rib 42 and the ratchet plate 4 are used to lock the push rod 43. 1 is engaged with the ratchet teeth to drive the intermittent rotation of the ratchet disk 41. A through electromagnet 45 is welded on the right side of the fixed magnet 44. A spring 46 is bolted to the lower part of the positioning rib 42. The spring 46 is set as an elastic metal sheet. At the same time, the size of the positioning rib 42 is adapted to the size of the ratchet disk 41. At the same time, a sliding groove is opened on the left side of the push rod 43, and the size of the sliding groove is adapted to the size of the positioning rib 42. The moving belt of the push rod 43 moves synchronously with the positioning rib 42, so that the intermittent rotation of the ratchet disk 41 is driven by the positioning rib 42.

[0029] A support base 1 is rotatably connected to the lower part of the pressing block 31, and a rotating rod 2 is inserted into the interior of the supporting base 1. A bevel gear and a rotating wheel are arranged below the rotating rod 2. The rotating wheel is arranged concentrically with the ratchet plate 41. A mold groove 5 is opened on the surface of the supporting base 1. The number of the mold grooves 5 is not less than five. The specifications of each mold groove 5 are consistent and are evenly distributed with reference to the center of the support base 1. At the same time, the size of the mold groove 5 is matched with the size of the pressing block 31. The polymer raw material is injected into the mold groove 5, and the mold is automatically pressed by the rotation of the mold groove 5. At the same time, the mold groove 5 is automatically replaced by the rotation of the support base 1.

[0030] The working process and principle of the device are as follows: when the device is needed, the polymer raw material is injected into the inside of the mold groove 5, and the output shaft of the motor is movably connected with the special-shaped disk 33 to drive the special-shaped disk 33 to rotate. Since the special-shaped disk 33 is arranged to be composed of two arcs with different radii, a displacement difference will be generated when the special-shaped disk 33 rotates, thereby driving the push plate 32 to intermittently reciprocate up and down. A pressing block 31 is arranged under the push plate 32, so it will drive the pressing block 31 to move synchronously and intermittently up and down, and the pressing block 31 is arranged directly above the mold groove 5, so that the polymer raw material in the mold groove 5 is automatically pressed by the pressing block 31.

[0031] At the same time, when the pressing block 31 moves downward, the limiting rods 34 at both ends of the pressing block 31 will be driven to move downward synchronously. When the limiting rods 34 move downward, since the hydraulic box 35 is filled with an incompressible solution, when the limiting rods 34 move downward, the pushing block 36 will be pushed to the right, thereby driving the sliding piece arranged on the surface of the connecting plate 37 to move synchronously along the resistance wire wound on the surface of the insulating rod 38, so that the number of resistance wires connected to the circuit is reduced, that is, the current is increased, so that the power supply is turned on, and the power supply is electrically connected to the electromagnet 45, so that the electromagnet 45 generates magnetism after being energized, and the magnetism is opposite to the magnetism of the fixed magnet 44, and opposite charges attract each other, driving the fixed magnet 44 to move to the right. The push rod 43 is used to drive the positioning rib 42 to move synchronously to the right. In the original state, the positioning rib 42 and the ratchet disk 41 are engaged with each other, so the ratchet disk 41 is driven to rotate, and the positioning rib 42 squeezes the spring plate 46, so that the positioning rib 42 moves downward and loses the engagement. Similarly, when the power is disconnected, the positioning rib 42 returns to its original position, so it eventually drives the ratchet disk 41 to rotate intermittently. A bevel gear and a rotating wheel are provided under the rotating rod 2, and the rotating wheel rotates synchronously with the ratchet disk 41, so it drives the rotating rod 2 to rotate synchronously and intermittently, thereby driving the support seat 1 sleeved on the outer surface of the rotating rod 2 to rotate synchronously, so that the mold groove 5 can be automatically replaced after the pressing is completed, thereby improving the working efficiency of the polymer material pressing.

[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.
