[0015] Compared with the existing technology, the advantages of the above-mentioned automatic demolding machine for producing anti-static labor protection shoes based on waste plastic utilization are as follows: 1. An initial separation mechanism is provided. The engagement of the gear and the toothed plate enables the toothed plate 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 contact between the outer wall of the finished anti-static labor protection shoes presented inside the mold and the inner wall of the mold becomes loose and separated. At the same time, multiple push columns intermittently push the knocking plate to rotate. With the reverse elastic force of the return spring, the knocking plate continuously knocks on the outer wall of the mold, causing the mold to vibrate. The vibration accelerates the separation of the formed finished product from the inner wall of the mold. 2. A separation mechanism is provided. 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 and the magnet plate face each other, under the action of magnetic repulsion, the movable frame is pushed to move. With the reverse elastic force of the telescopic spring and the connecting spring, the movable frame moves back, realizing the front-back, left-right movement of the movable frame, pushing the edge of the formed finished product inward, and further loosening and separating the contact between the finished product and the mold. 3. The swing rod drives the rotating dial plate to rotate. When the rotating dial plate rotates to contact the piston column, it pushes the piston column to move into the piston tube, squeezing the gas in the piston tube into the demolding hole, and then jacking up the bottom of the finished product to make it loose. 4. Set a separating mechanism. The driving end of the second oil cylinder extends to drive the cross plate to move downward, making the vacuum suction cup contact with the finished product. Start the vacuum suction cup to adsorb the finished product, and then the finished product can be taken out by retracting the driving end of the second oil cylinder; In summary, the present invention realizes heating the mold and knocking and vibrating to separate the shoe finished product from the inner wall of the mold by setting a preliminary separation mechanism, sets a separation structure to push the connection between the edge of the shoe finished product and the mold, and combines the flow of air in the demolding hole to accelerate the separation from the inner wall of the mold, ensuring that the subsequent taking-out mechanism can easily take out the shoe finished product, avoiding the pulling damage of the shoe finished product caused by the adhesion between the shoe finished product and the inner wall of the mold, and ensuring the quality of the shoe finished product.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

The movable groove 3 is provided with a braking mechanism. The braking mechanism includes a hydraulic cylinder fixedly embedded in the movable groove 3. The driving end of the hydraulic cylinder is fixedly connected with a friction plate arranged toward the outer wall of the base 1. The sleeve plate 2 and the mold are moved forward by the rotation of the electric roller 36. The mold moves to the initial separation mechanism, the disengagement mechanism and the removal mechanism in turn. After moving to one place, the electric roller 36 is turned off, and the friction plate is extended through the hydraulic cylinder to press against the outer wall of the base 1 to complete the fixation of the sleeve plate 2 and the mold position.

[0020] The mold includes a lower mold 4 and an upper mold 5 that is mounted on the lower mold 4 and rotates through a motor 39. An initial separation mechanism, a detachment mechanism, and a taking-out mechanism are provided on the base 1. The initial separation mechanism includes a motor 12 fixed to the base 1. A gear 13 is fixed to the driving end of the motor 12. A toothed plate 11 meshing with the gear 13 is provided on the base 1. A heating frame 15 is fixedly connected to the upper side wall of the toothed plate 11. A chute 37 is formed on the base 1. A sliding plate 10 that slides in the chute 37 is fixedly connected to the lower side wall of the heating frame 15. A limiting plate 17 is also fixed to the outer wall of the base 1. The heating frame 15 is slidably sleeved on the limiting plate 17. The limiting plate 17 guides the movement of the heating frame 15 to make the forward and backward movement of the heating frame 15 more stable. The molten waste plastic is injected into the mold for shaping. After cooling, the shaping work 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. The toothed plate 11 and the heating frame 15 are driven to move through the meshing of the gear 13 and the toothed plate 11. 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 the heat, the contact part between the outer wall of the finished labor protection shoe presented inside the mold 4 and the inner wall of the mold becomes loose and detached, facilitating the subsequent taking-out of the finished product.

[0021] 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 knocking plate 8 is fixedly sleeved at one end of the swing rod 7 close to the toothed plate 11. A return spring 9 is fixedly connected between the knocking plate 8 and the outer wall of the support platform 6. A plurality of push columns 14 for pushing the knocking plate 8 to rotate are uniformly fixed on the outer side wall of the toothed plate 11 close to the knocking plate 8. The detachment mechanism includes a movable frame 27 that reciprocates back and forth and left and right. The taking-out mechanism includes a vacuum suction cup 19. The formed workpiece is taken out through the initial separation mechanism, the detachment mechanism, and the taking-out mechanism in sequence. During the process of the heating frame 15 moving to heat the mold, the push column 14 on the outer wall of the toothed plate 11 contacts the lower end of the knocking plate 8, pushing the lower end of the knocking plate 8 to rotate towards one side of the mold. At the same time, the return spring 9 is twisted. When the push column 14 continues to move forward and disengages from the lower end of the knocking plate 8, the knocking plate 8 rotates back under the reverse elastic force of the return spring 9. The upper end of the knocking plate 8 contacts the outer wall of the mold, knocking the mold to generate vibration. Through the vibration, the formed finished product is accelerated to disengage from the inner wall of the mold. After the push column 14 disengages, as the toothed plate 11 moves, the next push column 14 continues to contact the knocking plate 8, pushing the knocking plate 8 to rotate. Thus, through the contact between the plurality of push columns 14 and the knocking plate 8, the mold is continuously knocked to generate vibration.

[0022] A demolding hole 38 is provided at the inner bottom of the lower mold 4. A ejector pin is provided in the demolding hole 38. The demolding hole 38 and the ejector pin are components equipped in existing molds. The ejector pin is lifted and lowered by the self-provided jacking mechanism of the mold. The mainstream solution uses a hydraulic cylinder or a telescopic rod as the power source, and the ejection speed and stroke are precisely adjusted through a controller to ensure the synchronism of the ejector pins.

[0023] A piston tube 31 communicating with the demolding hole 38 is arranged on the outer wall of the lower mold 4. A piston column 32 is slidably arranged in the piston tube 31. A return spring 33 is sleeved on the outer wall of the piston column 32. The end of the swing rod 7 is fixedly connected with a rotating dial 30 located outside the end of the piston column 32. An opening matching the piston tube 31 is formed in the heating frame 15. After the mold is heated by the heating frame 15 and vibrated by the knocking of the knocking plate 8, the heating frame 15 moves back to its original position. The motor 39 turns up the upper mold 5. The mold continues to move to the separating mechanism. The next mold moves to the initial separating mechanism for heating and knocking treatment. The ejector pin at the bottom of the mold retracts. While the knocking plate 8 rotates, it drives the swing rod 7 and the rotating dial 30 to rotate. When the rotating dial 30 rotates to contact the piston column 32, it pushes the piston column 32 to move into the piston tube 31, squeezing the gas in the piston tube 31 into the demolding hole 38, thereby jacking up the bottom of the finished product to loosen it.

[0024] The disengagement mechanism includes a right-angle plate 22 fixed on the base 1, an oil cylinder 23 is fixed at the end of the right-angle plate 22, and the driving end of the oil cylinder 23 is vertically fixedly connected to the front and rear guide plates 24 downward, and the front and rear guide plates 24 are slidably sleeved with left and right guide plates 25, and the movable frame 27 is slidably sleeved on the outer walls 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 walls of the right-angle plate 22, and 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 walls of the left and right guide plates 25 and The outer wall of the movable frame 27 is fixedly connected, and a plurality of magnet blocks 29 are fixedly connected to the outer wall of the front and rear guide plates 24 on one side close to the movable frame 27. A plurality of magnet plates are fixedly embedded on the outer wall of the movable frame 27 on one side close to the magnet block 29. A rotating shaft 20 is also installed on the upper side wall of the base 1. The rotating shaft 20 and the driving end of the motor 12 are fixedly sleeved with a pulley 18. The two pulleys 18 are jointly sleeved with a belt 21. A push plate 34 that pushes the movable frame 27 is fixedly connected to the outer wall of the upper end of the rotating shaft 20. After the mold moves to the disengagement mechanism, the oil cylinder 23 The driving end of the movable frame 27 extends outward, so that the movable frame 27 moves downward and contacts the upper side wall of the lower mold 4, so that the movable frame 27 is located outside the finished product in the lower mold 4. While the motor 12 drives the gear 13 to rotate, the power is transmitted through the pulley 18 and the belt 21, driving the rotating shaft 20 and the push plate 34 to rotate. When the end of the push plate 34 contacts the outer wall of the end of the movable frame 27, the movable frame 27 is pushed 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 27, when the magnet block 29 is opposite to the magnet plate, the movable frame 27 is pushed to the left under the action of magnetic repulsion, and the connecting spring 28 is squeezed at the same time. When the movable frame 27 moves to the point where the magnet block 29 is offset from the magnet plate, the movable frame 27 moves to the right under the reverse elastic force of the connecting spring 28. The movable frame 27 can be moved forward, backward, left and right by the above actions. During the movement of the movable frame 27, the edge of the formed finished product can be pushed inward, so that the contact between the finished product and the mold is further loosened and detached, thereby facilitating the subsequent removal of the finished product.

[0025] The taking-out mechanism further includes a second right-angle plate 40 arranged on the base 1 and driven to rotate by a motor. A second oil cylinder 41 is fixed to the end of the second right-angle plate 40. The driving end of the second oil cylinder 41 is fixedly connected vertically downward to a cross plate 16. A vacuum suction cup 19 is installed on the lower side wall of the cross plate 16. The vacuum suction cup 19 is an industrial pneumatic component designed based on the principle of pressure difference and is widely used in fields such as object adsorption, handling, and precision machining. By pumping out the air inside the suction cup through a vacuum pump or a vacuum generator, a negative pressure environment is formed, and the atmospheric pressure is used to tightly adsorb the finished shoes on the surface of the suction cup. After the mold passes through the initial separation mechanism and the detachment mechanism, the finished product formed inside it has been loosened and detached from its inner wall. After the mold continues to move to the taking-out mechanism and stops, the driving end of the second oil cylinder 41 extends to drive the cross plate 16 to move downward, so that the vacuum suction cup 19 contacts the finished product. The vacuum suction cup 19 is started to adsorb the finished product, and then the finished product can be taken out by retracting the driving end of the second oil cylinder 41.

[0026] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
