DETAILED DESCRIPTION
[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] Embodiment 1: Figure 1 - Figure 2 As shown, an anti-adhesion injection mold comprises a processing table 1, a connecting plate 2 is fixedly connected to the top of the processing table 1, a guide rail 3 is fixedly connected to one side of the connecting plate 2, a forming mold 4 is slidably connected to the surface of the guide rail 3, an electric cylinder 5 fixedly connected to the connecting plate 2 is fixedly connected to one side of the forming mold 4, an ejector pin 7 is slidably connected to the inside of the forming mold 4, an injection mold 6 fixedly connected to the tail of the guide rail 3 is fixedly connected to the top of the processing table 1, an injection hole 8 is fixedly connected to one side of the injection mold 6, a motor 9 is fixedly connected to the surface of the injection mold 6, and the output of the motor 9 The output end is fixedly connected with a positive and negative screw rod 10 which is rotatably connected to the inner wall of the injection mold 6, and the surface of the positive and negative screw rod 10 is threadedly connected with two groups of transmission blocks 11, and the bottom of the two groups of transmission blocks 11 is slidably connected with a limit plate 12 which is fixedly connected to the inner wall of the injection mold 6, and one side of the two groups of transmission blocks 11 is fitted with a force block 13, and one side of the two groups of processing tables 1 is fixedly connected with a mounting plate 14, and the right side of the mounting plate 14 is fixedly connected with a spring 15 which is fixedly connected to the inner wall of the injection mold 6, and the left side of the mounting plate 14 is fixedly connected with an ejection ring 16 which is slidably connected to the inside of the injection mold 6.
[0025] Furthermore, the molding mold 4 and the injection mold 6 are located on the same horizontal line. The molding mold 4 forms a sliding structure along the guide rail 3 through the electric cylinder 5. The electric cylinder 5 is turned on to push the molding mold 4. The molding mold 4 approaches the injection mold 6 along the guide rail 3 and finally fits with it. At this time, the material inside the injection hole 8 will be injected into the molding mold 4.
[0026] Furthermore, the forward and reverse screw rods 10 drive the two groups of transmission blocks 11 to form a reverse sliding structure along the limit plate 12. The forward and reverse screw rods 10 are controlled to rotate by the motor 9. When they rotate, they drive the two groups of transmission blocks 11 to move away from each other along the inside of the limit plate 12.
[0027] Furthermore, the ejector ring 16 is flush with the left side surface of the injection mold 6, and the spring 15 is set at the center of the mounting plate 14. When the transmission block 11 moves, it will break contact with the force block 13. At this time, under the elastic force of the spring 15, the mounting plate 14 will be pushed to move to the left side. The mounting plate 14 then pushes the ejector ring 16 to move to the left side and out of the injection mold 6 to push away the objects adhered to the injection mold 6.
[0028] Furthermore, the fitting surfaces of the transmission block 11 and the force block 13 are inclined surfaces to each other, and the force block 13 drives the spring 15 through the transmission block 11 to form a sliding structure inside the injection mold 6. When the two groups of transmission blocks 11 approach each other, the inclined surface will control the two groups of force blocks 13 to move to the left, so that the two groups of force blocks 13 drive the ejection ring 16 to be hidden inside the injection mold 6 again.
[0029] Embodiment 2: Figure 3 - Figure 6 As shown, a protective cover 17 is fixedly connected to the top of the processing table 1, a taking port 18 is opened on the top of the protective cover 17, and a cover plate 19 is provided on one side of the taking port 18 and is slidably connected to the top of the protective cover 17.
[0030] Furthermore, the protective cover 17 is made of transparent tempered glass, and the taking port 18 is located on the movement track of the cover plate 19. By setting the protective cover 17, the protective cover 17 can cover the equipment to achieve the purpose of protecting the equipment. At the same time, the protective cover 17 is transparently designed, allowing the operator to view the internal processing conditions from the outside.
[0031] Working principle: When using the anti-adhesion injection mold, first, turn on the electric cylinder 5 to push the molding mold 4. The molding mold 4 approaches the injection mold 6 along the guide rail 3 and finally fits with it. At this time, the material inside the injection hole 8 will be injected into the molding mold 4. The cooling system inside the molding mold 4 will mold the material inside the molding mold 4. Then the molding mold 4 moves away from the injection mold 6, and finally the molded object is ejected by the ejector pin 7.
[0032] When the formed mold is stuck inside the injection mold 6 and cannot be taken out normally, the forward and reverse screws 10 can be controlled to rotate by the motor 9. When they rotate, they will drive the two sets of transmission blocks 11 to move away from each other along the inside of the limit plate 12. When the transmission blocks 11 move, they will break contact with the force blocks 13. At this time, under the elastic force of the spring 15, the mounting plate 14 will be pushed to move to the left, and the mounting plate 14 will push the ejection ring 16 to move to the left and out of the injection mold 6 to push away the objects stuck to the injection mold 6, thereby achieving the purpose of avoiding adhesion.
[0033] By setting the protective cover 17, the protective cover 17 can cover the equipment to achieve the purpose of protecting the equipment. At the same time, the protective cover 17 is transparent, so that the operator can view the internal processing conditions from the outside. By setting the taking port 18, the taking port 18 can be convenient for the clamp to clamp the processed injection molded parts. When the equipment is not in use, the cover plate 19 can be slid to the right to cover the taking port 18 to prevent dust from falling onto the equipment from the taking port 18.
[0034] The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
