[0027] Compared with the prior art, the beneficial effects of the present invention are: the waste material recyclable inner cavity anti-sticking injection mold adopts a new structural design, and its specific contents are as follows:

[0028] During the use of this waste material recycling and anti-sticking injection mold, the material enters the auxiliary plate and the molding groove through the injection head, and is finally molded in the molding groove. After that, the moving plate is driven to move to the left side of the long pin by the electric telescopic rod.

At this time, the push block rotates synchronously, and the push block is distributed at equal angles on the lower surface of the disc. At this time, the slider will make reciprocating linear motion in the vertical direction under the action of the push block thrust, the side plate and the elastic force of the first spring. Then, during the unloading process, the molding plate is in a state of slight vibration, which is convenient for unloading.

[0031] (3) When the waste can be recycled, the inner cavity anti-sticking injection mold will be detected by the detection head when there is residual material on the inner wall of the molding groove. At this time, the high-pressure jet tube will work to blow the material away, and the material will fall on the receiving plate and fall directly through the mesh structure of the receiving plate, realizing the function of product and debris diversion, which is convenient for the staff to collect the waste;

[0032] (4) In the waste recycling and anti-sticking injection mold, during the operation of the moving plate, the second magnets on the surface of the receiving plate, which are evenly spaced, will approach and move away from the first magnets on the surface of the long rod one by one, and then the receiving plate will be intermittently subjected to the mutually repulsive magnetic force. At this time, the receiving plate will make reciprocating linear motion in the horizontal direction under the action of the mutually repulsive magnetic force, the lower connecting block, the limit rod and the reset spring, and then the receiving plate will be in a vibrating state, which is convenient for the rapid discharge of waste;

[0033] (5) The waste material can be recycled and the inner cavity anti-sticking injection mold has a material receiving plate in an inclined state, which can make the molded product slide quickly to the right side and be collected by the staff, thereby improving work efficiency.

[0053] Cooling pipes 10, the cooling pipes 10 are fixedly connected to both sides of the forming plate 8, and the ends of the cooling pipes 10 are connected to the external cooling system, and the upper surface of the forming plate 8 is fixedly connected with an upper connecting block 15, and the upper surface of the forming plate 8 is rotatably provided with a connecting shaft 11;

[0054] The slider 16 is slidably arranged inside the upper connecting block 15, and the left and right sides of the slider 16 are fixedly connected with the side connecting plates 17, and the material receiving plate 22, the lower surface of the material receiving plate 22 is fixedly connected with the lower connecting block 28, and the lower connecting block 28 is penetrated by the limiting rod 29, and the material receiving plate 22 is a mesh structure, and the material receiving plate 22 is distributed in an inclined shape;

[0055] The detection head 23 is fixedly connected to the surface of the auxiliary plate 7 , and the surface of the auxiliary plate 7 is fixedly connected with a high-pressure jet pipe 24 and a long rod 25 , and the long rod 25 is fixedly connected to the lower left end of the docking plate 4 .

[0056] A cross bar 19 is slidably provided inside the forming plate 8, and the cross bar 19 is symmetrically distributed about the center of the forming plate 8, and the end of the cross bar 19 is flush with the end of the forming groove 9. The cross bar 19 runs through the interior of the movable plate 3, and the end of the cross bar 19 is fixedly connected to the limiting plate 20, and the end of the cross bar 19 is convex.

[0057] A second spring 21 having an elastic reset function is fixedly connected to the surface of the limit plate 20, and the other side of the second spring 21 is fixedly connected to the left surface of the movable plate 3. A groove corresponding to the raised position at the end of the cross bar 19 is provided on the surface of the forming plate 8.

[0058] During use, the raw material enters the auxiliary plate 7 and the molding groove 9 through the injection head 5, and the cooling tube 10 accelerates the cooling of the material, and finally forms it in the molding groove 9, and then the movable plate 3 is driven by the electric telescopic rod 2 to move to the left position of the long pin 6. During the movement process, the limit plate 20 and the cross bar 19 will eventually be supported by the mounting plate 1. At this time, the limit plate 20 and the cross bar 19 move to the right, and then the second spring 21 is squeezed.

[0059] Embodiment 2: By setting up the auxiliary unloading structure, the unloading speed is increased and the generation of waste is avoided. Figure 5 and Figure 6 As shown:

[0060] A traction rope 12 is wrapped and fixedly connected to the surface of the connecting shaft 11, and the other side of the traction rope 12 is fixedly connected to the left surface of the docking plate 4, and the upper surface of the connecting shaft 11 is convex, and a disc 13 is fixedly connected to the middle lower end surface of the connecting shaft 11, and a push block 14 is fixedly connected to the lower surface of the disc 13, and the left and right sides of the push block 14 are inclined, and the push blocks 14 are distributed at equal angles on the lower surface of the disc 13.

[0061] The slider 16 passes through the interior of the upper connecting block 15, and the upper connecting block 15 is an inverted "U" shape when viewed from the side. The lower surface of the side connecting plate 17 is fixedly connected to a first spring 18 that plays an elastic reset role, and the other side of the first spring 18 is fixedly connected to the upper surface of the forming plate 8.

[0062] When the electric telescopic rod 2 drives the movable plate 3 to move to the left side of the long pin 6, the connecting shaft 11 and the disc 13 are driven to rotate by the traction rope 12. At this time, the push block 14 rotates synchronously, and the push block 14 is distributed at equal angles on the lower surface of the disc 13, and then the push block 14 will intermittently push the slider 16. When the slider 16 is pushed, the slider 16 descends inside the upper connecting block 15. At this time, the side connecting plate 17 will squeeze the first spring 18, and when the slider 16 is not pushed by the push block 14, the slider 16 rises under the action of the side connecting plate 17 and the first spring 18. Repeating the above process, the slider 16 will make reciprocating linear motion in the vertical direction, and the slider 16 will tap the upper surface of the forming plate 8.

When the connecting shaft 11 rotates, the traction rope 12 will be reeled in for the next use. At the same time, the convex shape on the upper surface of the connecting shaft 11 makes the traction rope 12 more stable when working.

[0069] The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.
