[0041] Referring toFigures 6-8 The demolding assembly includes a slant block 12, with a movable rod 11 slidably connected to its inner wall. A groove is formed on the slant block 12. When the movable rod 11 presses against the groove, the slant block 12 moves back and forth. A hollow tube sleeve 10 is slidably connected to the outer wall of the movable rod 11, allowing the movable rod 11 to move vertically. An ejector pin 13 is slidably connected to the upper surface of the slant block 12. A slanted surface with a groove is provided on the slant block 12. When the groove presses against the ejector pin 13, the ejector pin 13 moves vertically. The slant block 12 is slidably connected to the lower mold 1. On the inner wall of the mold, the lower mold 1 has a slot corresponding to the inclined block 12, allowing the inclined block 12 to move back and forth. The sleeve 10 is fixedly connected to the bottom end of the upper mold 2. The movable rod 11 is inserted into the bottom end of the upper mold 2. The upper mold 2 has a slot corresponding to the movable rod 11. Since the sleeve 10 is hollow, the movable rod 11 is not obstructed when inserted into the upper mold 2. The ejector pin 13 is slidably connected to the inner wall of the lower mold 1. The lower mold 1 has a slot corresponding to the ejector pin 13, allowing the ejector pin 13 to move vertically.

[0042] Reference Figures 3-5 The bottom end of the movable piece 6 is fixedly connected to one end of the movable spring 7, and the other end of the movable spring 7 is fixedly connected to the inner wall of the top of the upper mold 2. When the movable piece 6 moves upward, the movable spring 7 is stretched. When resetting, the elastic force of the movable spring 7 carries the movable piece 6 back to its original position. The outer wall of the rotating page 8 is fixedly connected to one end of the torsion spring 9, and the other end of the torsion spring 9 is fixedly connected to the inner wall of the upper mold 2. When the rotating page 8 rotates clockwise, the torsion spring 9 is compressed. When resetting, the elastic force of the torsion spring 9 carries the rotating page 8 back to its original position. The initial torque of the torsion spring 9 is below 0.1 N·m, and it is relatively easy to deform under the influence of a certain air pressure. , The rotating page 8 has a protrusion and a set of openings. The left end of the openings is initially blocked. When the gas squeezes the protrusion, the rotating page 8 rotates 45 degrees clockwise. At this time, the left end of the opening is connected to the vent. The water pipe 4 is inserted into the inner wall of the upper mold 2. The pipe in the upper mold 2 is slightly larger than the water pipe 4, so that the water pipe 4 can be inserted into the pipe. The top end of the water pipe 4 contacts the bottom end of the movable piece 6. A long rod is provided on the water pipe 4. When the long rod squeezes the movable piece 6, the movable piece 6 moves upward. The bottom end of the upper mold 2 contacts the top end of the lower mold 1. The movable piece 6 is slidably connected to the inner wall of the upper mold 2. The upper mold 2 has a slot corresponding to the movable piece 6, so that the movable piece 6 can move vertically.

[0043] Working principle: when injection molding is needed, the upper mold 2 is connected to the telescopic device controlled by the external electric control, and the upper mold 2 moves downward along the guide column 3. At this time, the upper mold 2 will move downward with the pipe sleeve 10. When the movable rod 11 contacts the top end of the slot in the upper mold 2, the upper mold 2 will move downward with the movable rod 11. The movable rod 11 will extrude the inclined groove on the inclined block 12, so that the inclined block 12 moves backward. The slot on the inclined surface of the inclined block 12 will extrude the ejector pin 13, so that the ejector pin 13 moves downward into the lower mold 1. At this time, the upper mold 2 and the lower mold 1 are closed, and injection molding can be performed through the injection port on the upper mold 2.

[0044] When injection molding is needed, the plastic particles flowing into the mold will extrude the air in the mold, so that the air is discharged from the air hole. At this time, the air will extrude the protruding block on the rotating page 8, so that the rotating page 8 deflects clockwise and extrudes the torsional spring 9. When the rotating page 8 deflects by 45 degrees, the opening on the rotating page 8 is in communication with the air hole, and the gas is discharged from the air hole. When the gas is discharged, the rotating page 8 is deflected back to the initial position under the elastic force of the torsional spring 9. The opening on the rotating page 8 is re-occluded to prevent dust from entering the mold from the air hole.

[0045] When water cooling of the mold is needed, the water pipe 4 is inserted into the pipe of the upper mold 2 when the upper mold 2 and the lower mold 1 are in contact. At the same time, the long rod on the water pipe 4 extrudes the movable piece 6, so that the movable piece 6 moves upward and stretches the movable spring 7. At this time, the fixed piece 5 and the movable piece 6 are separated, and the movable piece 6 no longer occludes the pipe. Water is injected through the water inlet in the lower mold 1 to flow into the pipe, so as to cool the products in the upper mold 2 and the lower mold 1.

[0046] When the product is needed to be taken out, the electric control moves the upper mold 2 upward. The upper mold 2 will move upward with the pipe sleeve 10 and the movable piece 6. When the movable piece 6 is no longer in contact with the long rod on the water pipe 4, the movable piece 6 is moved to the initial position by the elastic force of the movable spring 7. The movable piece 6 and the fixed piece 5 occlude the pipe. With the continuous upward movement of the pipe sleeve 10, the pipe sleeve 10 will move upward with the movable rod 11. The movable rod 11 will extrude the slot of the inclined block 12, so that the inclined block 12 moves forward. The inclined block 12 will extrude the ejector pin 13 upward, and the ejector pin 13 will eject the product from the lower mold 1. At this time, the worker can take out the product. When the product is produced again, only the above operation steps need to be repeated.

[0047] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
