[0002] Injection molding technology is widely used in the manufacturing industry, and the mold is one of the important tools for injection molding. For example, patent number CN214982468U is a plastic mold for printer production. The patent utilizes the cooperation of the first spring and the second spring to buffer the impact force on the upper template and the lower template, thereby preventing the contact surface of the upper template and the lower template from being damaged by the impact force and extending their service life.

This is very dangerous for the operator and there are certain operational safety hazards. Secondly, manual demolding and material removal is itself inefficient. If the operation is improper, the formed workpiece may be pulled and damaged. Therefore, it is necessary to improve the shortcomings and defects of the prior art. Utility Model Content

[0024] A U-shaped frame 51 is provided on the reciprocating drive assembly 5, and the U-shaped frame 51 is fixedly connected to the upper side of the base plate 1. A hydraulic telescopic rod 1 52 is fixedly connected to the upper side of the U-shaped frame 51, and a U-shaped block 53 is fixedly connected to the power output end of the hydraulic telescopic rod 1 52. The bottom of the U-shaped block 53 is rotatably connected to a rotating rod 1 54 and a rotating rod 2 55.

[0025] A plate 31 is provided on the movable component 3, and the plate 31 is fixedly connected to the molded plate 30 through a connecting plate 32 in the direction close to the fixed component 4. The bottom of the plate 31 is slidably connected to the linear guide rail 11, and a circular hole is preset on the plate 31 to maintain a slidable connection with the limiting slide rod 21. The rotating rod 1 54 and the rotating rod 2 55 are respectively hinged to the back plate 2 and the connecting shaft 311 on the side of the plate 31.

[0026] A plate 2 41 is provided on the fixed component 4, and the plate 2 41 is fixedly connected to the mold plate 2 40 through a connecting plate 2 42 in the direction close to the mold plate 1 30. A circular hole is preset on the plate 2 41 to maintain a sliding connection with the limiting slide rod 21. An injection port 43 is preset in the middle position of the top of the mold plate 2 40, and the injection port 43 is connected to the output pipe connected to the end of the injection mechanism 7.

[0027] The demoulding mechanism 8 is provided with a hydraulic telescopic rod 81, which is fixedly connected to the side of the back plate 2. The power output end of the hydraulic telescopic rod 81 is fixedly connected to a push plate 82.

[0028] A discharge port 9 is provided through the bottom plate 1 , and the discharge port 9 is located between the first mold plate 30 and the second mold plate 40 .

[0029] A support frame 10 is fixedly mounted on the lower surface of the base plate 1 .

[0030] Working principle: When the utility model is used, the hydraulic telescopic rod 1 52 on the reciprocating drive assembly 5 is started by an external switch to drive the U-shaped block 53 to move downward. During the downward movement of the U-shaped block 53, the rotating rod 2 55 is driven to rotate. The rotating rod 2 55 uses the thrust in the horizontal direction to push the mold plate 1 30 on the movable assembly 3 to move horizontally in the direction close to the mold plate 2 40 on the fixed assembly 4. Since the movable assembly 3 can be kept moving on the upper side of the linear guide rail 11 and can keep sliding with the limit slide bars 21 on both sides, it is ensured that the mold plate 1 30 can accurately match after moving close to the mold plate 2 40. When the mold plate 1 30 and the mold plate 2 40 are combined, the injection molding mechanism 7 is started by an external switch to use the injection molding raw material output by the output pipe to complete the injection molding operation in the cavity of the area composed of the mold plate 1 30 and the mold plate 2 40 through the injection port 43;

[0031] When the raw material in the cavity is cooled and formed, the U-shaped block 53 on the reciprocating drive assembly 5 is started again to move upward, and the mold plate 30 is pulled back to its original position by rotating the second rotating rod 55. At this time, the formed printer plastic shell remains on the inner side of the mold plate 40. Finally, the hydraulic telescopic rod 81 on the demoulding mechanism 8 is started to drive the push rod 83 to move by the output end, and the printer plastic shell in the mold plate 40 is ejected outward to complete the automatic demoulding operation, thereby improving the processing efficiency. It should be noted that if Figure 5 As shown, the end of the push rod 83 is kept flush with one end of the circular hole in the mold plate 40 in the initial state, and is pushed out to the left from the circular hole when demolding is required. The plastic shell of the printer after demolding can fall downward from the discharge port 9, which is convenient for the operator to perform the material collection operation and avoids the safety hazard when the user manually takes the material from between the mold plate 1 30 and the mold plate 2 40.
