Description

Technical Field

[0001] This invention relates to the field of mold forming technology, and in particular to an automatic demolding machine for the production of antistatic work shoes based on the utilization of waste plastics. Background Technology

[0002] Shoe molds are key tools used for shaping in the shoe manufacturing process. They are mainly used in the production of athletic shoes, leather shoes, plastic shoes, and other footwear. Their materials include die-casting molds, copper molds, and steel molds, among which copper molds are superior in terms of thermal conductivity and durability.

[0003] A search revealed that Chinese patent CN118906359A discloses an automated rapid demolding mechanism and method for shoe mold cores in a shoe manufacturing production line. The mechanism includes an annular conveyor belt and a mold disposed on the upper surface of the conveyor belt. The outer surface of the conveyor belt is respectively equipped with a robotic arm for spraying a release agent onto the mold and an injection gun for injecting molding into the mold. A first support frame and a second support frame are respectively installed on the two sides of the conveyor belt near the robotic arm. A demolding mechanism is disposed on the surface of the second support frame. This application utilizes a shovel inserted into the gap between the mold and the shoe mold core, and uses the relative rotation of the two shovels to clamp and remove the shoe mold core. However, this direct clamping and removal method is prone to adhesion and tearing damage, thus affecting the quality of the finished product.

[0004] To address the aforementioned issues, we propose an automatic demolding machine for the production of antistatic safety shoes based on the utilization of waste plastics. Summary of the Invention

[0005] The purpose of this invention is to solve the problems in the background art by proposing an automatic demolding machine for the production of antistatic work shoes based on the utilization of waste plastics.

[0008] In the above-mentioned automatic demolding machine for producing antistatic safety shoes based on waste plastic utilization, the extraction mechanism further includes a right-angle plate II mounted on the base and driven to rotate by a motor. A hydraulic cylinder II is fixed to the end of the right-angle plate II, and a horizontal plate is fixedly connected to the driving end of the hydraulic cylinder II vertically downward. The vacuum suction cup is installed on the lower side wall of the horizontal plate.

[0009] In the above-mentioned automatic demolding machine for producing antistatic work shoes based on waste plastic utilization, a sliding groove is provided on the base, a sliding plate that slides in the sliding groove is fixedly connected to the lower side wall of the heating frame, a limiting plate is also fixed to the outer wall of the base, and the heating frame is slidably sleeved on the limiting plate.

[0010] In the above-mentioned automatic demolding machine for producing antistatic safety shoes based on waste plastic utilization, a demolding hole is provided at the bottom of the lower mold, an ejector pin is provided in the demolding hole, a piston tube communicating with the demolding hole is provided on the outer wall of the lower mold, a piston column is slidably provided in the piston tube, a return spring is sleeved on the outer wall of the piston column, and a rotating lever located outside the end of the piston column is fixedly connected to the end of the swing rod.

[0011] In the above-mentioned automatic demolding machine for producing antistatic safety shoes based on waste plastic utilization, the heating frame has an opening that matches the piston tube.

[0012] In the above-mentioned automatic demolding machine for producing antistatic work shoes based on waste plastic utilization, a movable groove is provided on the base, and the inner walls on both sides of the movable groove are integrally formed with inward flanges. A vertical plate is slidably arranged in the movable groove, and a sleeve plate sleeved on the outer wall of the base is fixedly connected to the upper end of the sliding plate. The mold is fixed on the outer wall of the sleeve plate, and an electric roller that contacts the inner wall of the movable groove is installed on the outer wall of the vertical plate.

[0013] In the above-mentioned automatic demolding machine for producing antistatic safety shoes based on waste plastic utilization, a braking mechanism is provided on the moving groove. The braking mechanism includes a hydraulic cylinder fixedly embedded in the moving groove, and a friction plate is fixedly connected to the driving end of the hydraulic cylinder facing the outer wall of the base.

[0014] Compared with existing technologies, the advantages of this automatic demolding machine for producing antistatic work shoes based on waste plastic utilization are:

[0015] 1. An initial separation mechanism is set up. The meshing of gears and toothed plates enables the toothed plates to drive the heating frame to move along the outside of the mold. The heat on the heating frame is transferred to the mold. Under the action of heat, the outer wall of the work shoe product inside the mold loosens and separates from the inner wall of the mold. At the same time, multiple push columns intermittently push the striking plate to rotate. With the help of the reverse elastic force of the return spring, the striking plate continuously strikes the outer wall of the mold, causing the mold to vibrate. The vibration accelerates the separation of the molded product from the inner wall of the mold.

[0016] 2. A release mechanism is set up. The rotating shaft drives the push plate to rotate. When the push plate contacts the movable frame, it pushes the movable frame to move. During the movement of the movable frame, when the magnet block is opposite to the magnet plate, the movable frame is pushed to move under the action of magnetic repulsion. The movable frame is moved back by the reverse elastic force of the telescopic spring and the connecting spring, realizing the forward, backward and left and right movement of the movable frame. The edge of the molded finished product is pushed inward, so that the contact point between the finished product and the mold is further loosened and released.

[0017] 3. The swing rod drives the rotating plate to rotate. When the rotating plate rotates to contact the piston column, it pushes the piston column into the piston tube, squeezing the gas in the piston tube into the demolding hole, thereby lifting and loosening the bottom of the finished product.

[0018] 4. Set up a release mechanism. The drive end of the second cylinder extends and moves the horizontal plate down, so that the vacuum suction cup comes into contact with the finished product. The vacuum suction cup is activated to adsorb the finished product. Then, the finished product can be taken out by retracting the drive end of the second cylinder.

[0019] In summary, this invention achieves the separation of the finished shoe from the inner wall of the mold by heating and vibrating the mold through a preliminary separation mechanism. The separation structure pushes the edge of the finished shoe at the connection with the mold, and combined with the airflow in the demolding hole, accelerates the separation from the inner wall of the mold. This ensures that the subsequent removal mechanism can easily remove the finished shoe, avoiding the tearing damage caused by the finished shoe sticking to the inner wall of the mold, and ensuring the quality of the finished shoe.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0032] Reference Figures 1-10 An automatic demolding machine for producing antistatic work shoes based on waste plastic utilization includes a base 1 and a mold mounted on the base 1. A movable groove 3 is formed on the base 1, and both inner walls of the movable groove 3 have inwardly flanged edges integrally formed. A vertical plate 35 is slidably mounted inside the movable groove 3. A sleeve plate 2 fitted onto the outer wall of the base 1 is fixedly connected to the upper end of the vertical plate 35. The mold is fixed to the outer wall of the sleeve plate 2. An electric roller 36 is installed on the outer wall of the vertical plate 35, contacting the inner wall of the movable groove 3. The flanges limit the electric roller 36, preventing it from detaching from the movable groove 3. The electric roller 36 can move stably along the moving groove 3. The moving groove 3 is equipped with a braking mechanism, which includes a hydraulic cylinder fixedly embedded in the moving groove 3. The driving end of the hydraulic cylinder is fixedly connected to a friction plate facing the outer wall of the base 1. The rotation of the electric roller 36 causes the sleeve plate 2 and the mold to move forward. The mold moves sequentially to the initial separation mechanism, the release mechanism and the take-out mechanism. After moving to one place, the electric roller 36 is turned off, and the friction plate is extended and pressed against the outer wall of the base 1 by the hydraulic cylinder, thus fixing the position of the sleeve plate 2 and the mold.

[0033] The mold includes a lower mold 4 and an upper mold 5 mounted on the lower mold 4 and rotated by a motor 39. A base 1 is provided with a preliminary separation mechanism, a release mechanism, and a take-out mechanism. The preliminary separation mechanism includes a motor 12 fixed to the base 1, a gear 13 fixed to the drive end of the motor 12, a gear plate 11 meshing with the gear 13 on the base 1, a heating frame 15 fixedly connected to the upper side wall of the gear plate 11, a sliding groove 37 on the base 1, a sliding plate 10 sliding within the sliding groove 37 fixedly connected to the lower side wall of the heating frame 15, and a limiting plate 17 fixed to the outer wall of the base 1. The heating frame 15 is slidably sleeved on the limiting plate 17. The movement of the heating frame 15 is guided to make its back-and-forth movement more stable. The molten waste plastic is injected into the mold for presentation. After cooling, the shaping process is completed. The heating frame 15 can be made of electrothermal alloy. After the mold moves to the initial separation mechanism, the motor 12 is started to drive the gear 13 to rotate. Through the meshing of the gear 13 and the toothed plate 11, the toothed plate 11 and the heating frame 15 are moved. The heating frame 15 moves along the outside of the mold. The heat on the heating frame 15 is transferred to the mold. Under the action of heat, the outer wall of the finished work shoe inside the mold 4 loosens and separates from the inner wall of the mold, making it easier to remove the finished product later.

[0034] A support platform 6 is fixed to the upper side wall of the base 1. A swing rod 7 is installed on the support platform 6. A striking plate 8 is fixedly sleeved on one end of the swing rod 7 near the toothed plate 11. A return spring 9 is fixedly connected between the striking plate 8 and the outer wall of the support platform 6. Multiple pushing columns 14 for pushing the striking plate 8 to rotate are evenly fixed on the outer wall of the toothed plate 11 near the striking plate 8. The detachment mechanism includes a movable frame 27 that moves back and forth and left and right. The extraction mechanism includes a vacuum suction cup 19. The formed workpiece is extracted by sequentially passing through the initial separation mechanism, the detachment mechanism, and the extraction mechanism. During the process of heating the mold by moving the heating frame 15, the pushing column of the outer wall of the toothed plate 11... When the lower end of the pusher 14 contacts the lower end of the striking plate 8, it pushes the lower end of the striking plate 8 to rotate towards one side of the mold. At the same time, the return spring 9 is twisted. When the pusher 14 continues to move forward and disengages from the lower end of the striking plate 8, the striking plate 8 rotates under the reverse elastic force of the return spring 9. The upper end of the striking plate 8 contacts the outer wall of the mold, and the striking of the mold generates vibration. The vibration accelerates the separation of the molded product from the inner wall of the mold. After the pusher 14 disengages, as the toothed plate 11 moves, the next pusher 14 continues to contact the striking plate 8, pushing the striking plate 8 to rotate. Thus, through the contact of multiple pushers 14 with the striking plate 8, the mold is continuously struck, causing the mold to vibrate.

[0035] The bottom of the lower mold 4 is provided with a demolding hole 38, and an ejector pin is provided in the demolding hole 38. The demolding hole 38 and the ejector pin are components that are equipped in existing molds. The ejector pin is raised and lowered by the mold's own lifting mechanism. The mainstream solution uses a hydraulic cylinder or telescopic rod as the power source. The ejection speed and stroke are precisely adjusted by the controller to ensure the synchronization of the ejector pin.

[0036] A piston tube 31 communicating with the demolding hole 38 is provided on the outer wall of the lower mold 4. A piston column 32 is slidably arranged inside the piston tube 31. A return spring 33 is sleeved on the outer wall of the piston column 32. A rotating plate 30 located outside the end of the piston column 32 is fixedly connected to the end of the swing rod 7. An opening matching the piston tube 31 is opened on the heating frame 15. After the mold is heated by the heating frame 15 and vibrated by the striking plate 8, the heating frame 15 moves back to its original position. The motor 39 rotates the upper mold 5. The mold continues to move to the separation mechanism. The next mold moves to the initial separation mechanism for heating and striking. The ejector pin at the bottom of the mold retracts. While the striking plate 8 rotates, it drives the swing rod 7 and the rotating plate 30 to rotate. The rotating plate 30 rotates until the piston column 32 contacts, pushing the piston column 32 into the piston tube 31, squeezing the gas in the piston tube 31 into the demolding hole 38, thereby lifting and loosening the bottom of the finished product.

[0037] The disengagement mechanism includes a right-angle plate 22 fixed to the base 1. A hydraulic cylinder 23 is fixed to the end of the right-angle plate 22. A front and rear guide plate 24 is vertically and downwardly fixed to the driving end of the hydraulic cylinder 23. Left and right guide plates 25 are slidably sleeved on the front and rear guide plates 24. A movable frame 27 is slidably sleeved on the outer wall of the left and right guide plates 25. A telescopic spring 26 is fixedly connected between the left and right guide plates 25 and the outer wall of the right-angle plate 22. A connecting spring 28 is sleeved on the left and right guide plates 25. The two ends of the connecting spring 28 are respectively connected to the outer wall of the left and right guide plates 25 and... The outer wall of the movable frame 27 is fixedly connected. Multiple magnet blocks 29 are fixedly connected to the outer wall of the front and rear guide plates 24 near the movable frame 27. Multiple magnet plates are fixedly embedded on the outer wall of the movable frame 27 near the magnet blocks 29. A rotating shaft 20 is also installed on the upper side wall of the base 1. Pulleys 18 are fixedly fitted onto both the rotating shaft 20 and the drive end of the motor 12. A belt 21 is fitted onto both pulleys 18. A push plate 34 that pushes the movable frame 27 is fixedly connected to the upper outer wall of the rotating shaft 20. After the mold moves to the disengagement mechanism, the hydraulic cylinder 23... The drive end extends, causing the movable frame 27 to move downwards and contact the upper side wall of the lower mold 4, positioning the movable frame 27 outside the finished product inside the lower mold 4. Simultaneously, the motor 12 drives the gear 13 to rotate, transmitting power through the pulley 18 and belt 21, causing the rotating shaft 20 and push plate 34 to rotate. When the end of the push plate 34 contacts the outer end wall of the movable frame 27, it pushes the movable frame 27 forward. At this time, the telescopic spring 26 is stretched. When the push plate 34 rotates away from the movable frame 27, the movable frame 27 moves backward under the reverse elastic force of the telescopic spring 26. During the forward movement of frame 27, when magnet block 29 is opposite to magnet plate, the magnetic repulsion force pushes movable frame 27 to the left, while the connecting spring 28 is squeezed. When movable frame 27 moves to the point where magnet block 29 and magnet plate are misaligned, movable frame 27 moves to the right under the reverse elastic force of connecting spring 28. Through the above actions, movable frame 27 can move forward, backward, left, and right. During the movement of movable frame 27, the edge of the molded finished product can be pushed inward, so that the contact point between the finished product and the mold is further loosened and separated, thus facilitating the subsequent removal of the finished product.

[0038] The extraction mechanism also includes a right-angle plate 40 mounted on the base 1 and driven to rotate by a motor. A hydraulic cylinder 41 is fixed to the end of the right-angle plate 40. A horizontal plate 16 is vertically fixed to the driving end of the hydraulic cylinder 41. A vacuum suction cup 19 is mounted on the lower side wall of the horizontal plate 16. The vacuum suction cup 19 is an industrial pneumatic component designed based on the principle of pressure difference. It is widely used in the fields of object adsorption, handling and precision machining. By using a vacuum pump or vacuum generator to extract the air inside the suction cup, a negative pressure environment is formed. Atmospheric pressure is used to tightly adsorb the finished shoe onto the surface of the suction cup. After the mold passes through the initial separation mechanism and the release mechanism, the finished product inside the mold has been loosened and separated from its inner wall. The mold continues to move to the extraction mechanism and stops. The driving end of the hydraulic cylinder 41 extends and drives the horizontal plate 16 to move down, so that the vacuum suction cup 19 contacts the finished product. The vacuum suction cup 19 is activated to adsorb the finished product. The finished product can then be extracted by retracting the driving end of the hydraulic cylinder 41.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
