With the continuous entering and discharging of the gas, the product will gradually and smoothly separate from the first mold base.

Description

Technical Field

[0001] This invention relates to the field of injection mold technology, and in particular to a rapid demolding mechanism for products used in injection molds. Background Technology

[0002] An injection mold is a tool used for injection molding. It is an important process equipment that uses a plastic molding machine to inject thermoplastic or thermosetting plastic into the mold cavity under high temperature and certain pressure. After cooling and solidification, plastic products of the desired shape and size are obtained.

[0003] Inadequate fit between the upper and lower molded modules results in shape discrepancies in the injection-molded LED product components, hindering later assembly and use. Furthermore, the severe roughness around the edges of the molded LED product components makes demolding extremely difficult. To address these issues, Chinese Patent CN107521046A discloses a rapid demolding mechanism for producing high-quality, durable LED product components. This mechanism includes an upper mold assembly and a lower mold assembly. The upper mold assembly comprises an upper mold base and an upper mold template, while the lower mold assembly includes a base plate, a support plate, a lower mold pad, and a lower mold template. Guide pillars and guide screws are installed between the lower mold base, upper mold assembly, and lower mold assembly to ensure accurate mold assembly fit and eliminate peripheral roughness. At the same time, the opening and closing of the gas-assisted component is controlled by the linkage between the ejector pin pad and the control switch. The ejector pin in the demolding assembly is combined with the gas-assisted component. Before mechanical demolding, the airtightness between the product component and the lower mold plate is broken first. The gas-assisted component and the ejector pin pad are fully linked. Therefore, damage to the component is greatly reduced during demolding, thereby ensuring the performance and lifespan of the manufactured product component.

[0004] The gas-assisted component in this mold only has the function of breaking the airtightness between the lower end of the product and the lower mold plate. Therefore, when the upper mold base and the lower mold base are separated, the product will still be firmly attached to the inside of the upper mold base. Based on this situation, in order to ensure that the product can be removed smoothly, the operator needs to perform additional manual demolding treatment on the product, which will not only affect production efficiency, but may also damage the product quality.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] (1) After the product inside the molding frame has successfully completed the molding process, the operator can first open all the ventilation mechanisms located in the ventilation holes, and then start the second air pump. At this time, fresh air from the outside will slowly enter the internal space of the cavity through the opened ventilation holes. The incoming air will gently collide with the surface of the product in a soft manner. Small gaps will gradually form on the contact surface between the first mold base and the product. The appearance of these gaps provides the necessary conditions for the smooth demolding of the product. During this process, excess gas will not accumulate in the cavity, but will be discharged by the exhaust pump in a stable and continuous manner. Outside the cavity, to ensure the balance of internal air pressure, as gas continuously enters and exits, the product will gradually and smoothly detach from the first mold base. After the product inside the molding frame has successfully completed the molding process, when the worker pulls the limiting plate out of the sliding frame, the sealing plate and baffle can detach from the product under the action of the pushing spring. When the adhesion between the product and the sealing plate is large, the ventilation mechanism in the first air inlet and the second air inlet can be opened in sequence, and the first air pump and the third air pump can continuously deliver gas to the frame to ensure that the product can be demolded smoothly, which helps to improve production efficiency and product quality.

[0026] (2) By setting the connection structure between the buckle plate and the slot plate, the first mold base and the second mold base can be fixed together. By setting the hanging ring, and using the hook and rope, the first mold base and the second mold base can be lifted and moved. By setting the wireless control module, it is convenient for the staff to remotely control the switching of multiple sets of cylinders at the same time. When the cylinder is turned on, the cylinder can slowly slide with the slip ring, and at the same time, the slip ring slowly moves away from the ventilation ring in the same air outlet. By setting the L-shaped bracket, the sealing rod can be connected with the slip ring. When the slip ring moves, the sealing rod will also move with it. When the slip ring slowly moves away from the ventilation ring in the same air outlet, the sealing rod will also fall off from the ventilation ring, and then the ventilation mechanism will be turned on.

[0027] (3) By setting a dustproof net, dust in the outside air can be prevented from entering the cavity. By setting a connection structure between the insert rod and the insertion hole, the quick splicing between the first mold base and the second mold base can be limited. The outer wall of the insert rod is close to the inner wall of the insertion hole, which can improve the stability of the connection structure between the first mold base and the second mold base, thereby preventing them from shaking. By setting a guide hole, the internal space of the cavity and the frame can be interconnected. Excess gas in the frame will pass through the guide hole into the cavity. When the gas comes into contact with the elastic ring, the gas will change its flow direction and collide with the outer wall of the molding frame. At this time, the molding frame will vibrate due to the external collision, which can quickly separate the outer wall of the product from the inner wall of the molding frame. After the product is removed from the molding frame, the vibrating molding frame can shake off all the powder of the injection molding material attached to the inner wall of the molding frame, ensuring the cleanliness of the molding frame.

[0037] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments. The present invention provides the following embodiments.

[0039] Reference Figure 1-6 This invention provides an embodiment of a rapid demolding mechanism for injection molds, comprising a first mold base 1, a second mold base 2 mounted on one side of the outer wall of the first mold base 1, a slotted plate 3 fixedly connected to both the front and rear ends of the first mold base 1, and a snap-fit ​​plate 4 fixedly connected to both the front and rear ends of the second mold base 2. One end of the outer wall of each snap-fit ​​plate 4 engages with one end of the inner wall of each slotted plate 3. By setting the connection structure between the snap-fit ​​plate 4 and the slotted plate 3, the first mold base 1 and the second mold base 2 can be fixed together. Each mold base 1 and the second mold base 2 are fixedly connected to a hanging ring 5. By using the hanging ring 5, hooks and ropes, the first mold base 1 and the second mold base 2 can be lifted and moved. One end of the outer wall of the second mold base 2 is provided with a first air inlet hole 6, and the other end of the outer wall of the second mold base 2 is provided with a second air inlet hole 7. The first air inlet hole 6 is located directly above the second air inlet hole 7. The shape and size of the first air inlet hole 6 are the same as those of the second air inlet hole 7. The first mold base 1 is provided with a ventilation hole 8 that penetrates the outer walls of both sides.

[0040] A sealing block 91 is fixedly connected to one end of the inner wall of the first air inlet 6, the second air inlet 7, and the vent 8. Multiple sets of air outlet holes 92 are formed in the sealing block 91. A cylinder 93 is fixedly connected to one end of the inner wall of each air outlet hole 92. A wireless control module 94 is fixedly connected to the end of each cylinder 93. The wireless control module 94 allows for remote control of the switching of multiple cylinders 93 simultaneously. A slip ring 95 is fixedly connected to the movable end of each cylinder 93. The outer wall of the slip ring 95 is slidably connected to the inner wall of each air outlet hole 92. An L-shaped bracket 96 is fixedly connected to one end of the outer wall of each slip ring 95. A sealing rod 97 is fixedly connected to one end of the outer wall of each L-shaped bracket 96. A sealing rod 97 is fixedly connected to the other end of the inner wall of each air outlet hole 92. The inner wall of the vent ring 98 is sleeved with the outer wall of the sealing rod 97. When the cylinder 93 is opened, the cylinder 93 can slowly slide the slip ring 95, and at the same time, the slip ring 95 slowly moves away from the vent ring 98 in the same air outlet 92. By setting the L-shaped bracket 96, the sealing rod 97 and the slip ring 95 can be connected together. When the slip ring 95 moves, the sealing rod 97 will also move with it. When the slip ring 95 slowly moves away from the vent ring 98 in the same air outlet 92, the sealing rod 97 will also fall off the vent ring 98. By setting the sealing block 91, air outlet 92, cylinder 93, wireless control module 94, slip ring 95, L-shaped bracket 96, sealing rod 97 and vent ring 98, the ventilation mechanism 9 can be formed.

[0041] A cavity 10 is formed at the center of the outer wall of the other side of the second mold base 2. A frame 22 is fixedly connected to one end of the inner wall of the cavity 10. A molding frame 23 is fixedly connected to the outer edge of one side of the outer wall of the frame 22. Multiple sets of insertion holes 11 are formed at the outer edge of the outer wall of the other side of the second mold base 2. Multiple sets of insertion rods 12 are fixedly connected to the outer edge of one side of the outer wall of the first mold base 1. The outer walls of the insertion rods 12 are all sleeved with the inner walls of the insertion holes 11. By setting the connection structure between the insertion rods 12 and the insertion holes 11, the quick splicing between the first mold base 1 and the second mold base 2 can be limited. It is worth noting that the outer walls of the insertion rods 12 are close to the inner walls of the insertion holes 11. The other end of the inner wall of the first air inlet hole 6 is fixedly connected to There is a first air intake pump 13, and a third air intake pump 14 is fixedly connected to the other end of the inner wall of the second air intake hole 7. A second air intake pump 15 is fixedly connected to the other end of the inner wall of the vent hole 8. The air inlets of the first air intake pump 13, the third air intake pump 14, and the second air intake pump 15 are all fixedly connected to dustproof nets 16. By setting dustproof nets 16, dust in the outside air can be prevented from entering the interior of the molding frame 23. One end of the outer wall of the first mold base 1 is penetrated by a feed pipe 17. After the first mold base 1 and the second mold base 2 are fixed together, the internal space of the feed pipe 17 is interconnected with the internal space of the molding frame 23. The operator can transport the injection molding material to the interior of the molding frame 23 through the feed pipe 17.

[0042] An exhaust pump 18 is installed at one end of the outer wall of the first mold base 1. When injection molding material is injected into the cavity 10, excess gas inside the molding frame 23 is discharged by the exhaust pump 18. It is worth noting that a filter screen is installed at the air inlet of the exhaust pump 18 to intercept the injection molding material. A wire 19 is fixedly connected to one end of the outer wall of the exhaust pump 18, and a control module 20 is fixedly connected to the end of the wire 19. The control module 20 and the wire 19 allow operators to easily control the operation of the exhaust pump 18. An exhaust pipe 21 is fixedly connected to the air outlet of the exhaust pump 18. The exhaust pipe 21 allows for the stable discharge of gas from the cavity 10. After the product inside the molding frame 23 has successfully completed the molding process, the operator can first fully open the ventilation mechanism 9 located in the ventilation hole 8 to ensure the ventilation channel is complete. With the flow fully unobstructed, the second air intake pump 15 is then activated. At this time, fresh air from the outside will slowly enter the internal space of the molding frame 23 through the already opened vent 8. The incoming air will gently collide with the surface of the product. This gentle air flow helps to reduce any potential damage to the product. At the same time, some small gaps will gradually form on the contact surface between the first mold base 1 and the product. The appearance of these gaps provides the necessary conditions for the smooth demolding of the product. During this process, excess gas will not accumulate in the molding frame 23, but will be discharged out of the cavity in a stable and continuous manner by the exhaust pump 18 to ensure the balance of internal air pressure. As the gas continues to enter and exit, the product will gradually and smoothly detach from the first mold base 1. The whole process is smooth and efficient, thereby achieving the effect of rapid demolding and greatly improving production efficiency and product quality.

[0043] Multiple sets of elastic rings 24 with good elasticity are fixedly connected to the other end of the inner wall of the cavity 10. These elastic rings 24 can effectively buffer and guide the gas flowing inside the cavity 10. A limiting ring 25 is fixedly connected to one end of the inner wall of the frame 22. The limiting ring 25 has precisely designed spring holes 26 at both ends of one side of its outer wall. A spring rod 27 is installed on one end of the inner wall of each spring hole 26 by a sliding connection. A push spring 28 with strong pushing force is sleeved on the other end of the inner wall of the spring hole 26. One end of the spring rod 27 is firmly fixed to the top of the push spring 28. By setting the push spring 28, it can effectively push the spring rod 27. A baffle 29 is fixedly connected to the other end of the spring rod 27. A sealing plate 30 is fixedly connected to the center of one side of the outer wall of the baffle 29. The outer wall of the sealing plate 30 is connected to the inner wall of the limiting ring 25. The walls are connected by a sleeve. By setting the sealing plate 30, the limiting ring 25 can be effectively sealed. One side of the outer wall of the sealing plate 30 can be in close contact with the surface of the product to ensure the sealing effect. Both ends of one side of the outer wall of the frame 22 are provided with guide holes 31. By setting the guide holes 31, the internal space of the cavity 10 and the frame 22 can be interconnected. Excess gas in the frame 22 will pass through the guide holes 31 and enter the cavity 10. When the gas comes into contact with the elastic ring 24, the gas will change its flow direction and collide with the outer wall of the molding frame 23. At this time, the molding frame 23 will vibrate due to the external collision, which can quickly separate the outer wall of the product from the inner wall of the molding frame 23. After the product is removed from the molding frame 23, the vibrating molding frame 23 can shake off all the powder of the injection molding material attached to the inner wall of the molding frame 23, ensuring the cleanliness of the molding frame 23.

[0044] A pad 32 is fixedly connected to the other end of the inner wall of the frame 22. Multiple sets of support rings 33 are arranged through the pad 32. Sliding rods 34 are installed on the inner walls of these support rings 33 using a sliding connection method, ensuring that the sliding rods 34 can slide smoothly within the support rings 33. A return spring 35 is sleeved on one end of the outer wall of each sliding rod 34. A blowing plate 36 is fixedly connected to one end of the sliding rod 34. The function of the return spring 35 is to provide a return force, allowing the sliding rod 34 and the fixedly connected blowing plate 36 to effectively return to their initial positions when needed. A rubber head 37 is fixedly connected to the other end of the sliding rod 34. By setting the return spring 35, not only can the sliding rod 34 be effectively reset, but the blowing plate 36 can also be ensured to return to its initial position. 6. During operation, maintain stability. When the ventilation mechanism 9 in the first air inlet 6 and the second air inlet 7 is opened in sequence, it is important to note that the ventilation mechanism 9 will switch back and forth between the open and closed states multiple times. During this switching process, the gas will directly act on the blowing plate 36, generating a pushing force, which will significantly push the slide rod 34 and the rubber head 37. At this time, the rubber head 37 will quickly collide with the surface of the baffle 29 under the push of the gas. Subsequently, the baffle 29 and the sealing plate 30 connected to it will generate obvious vibration under the action of the collision force. This vibration can effectively promote the sealing plate 30 to quickly detach from the product, thereby achieving the effect of rapid product demolding and improving production efficiency and product quality.

[0045] The rear end face of the second mold base 2 and the rear end face of the frame 22 are both penetrated by a sliding frame 38. The inner wall of the sliding frame 38 is fitted with a limiting plate 39. One end of the outer wall of the limiting plate 39 can extend into the interior of the frame 22 to fix the baffle 29. At this time, the sealing plate 30 is in contact with the product. After the product inside the molding frame 23 has successfully completed the molding process, when the worker pulls the limiting plate 39 out of the sliding frame 38, the sealing plate 30 and the baffle 29 can be separated from the product under the action of the pushing spring 28. When the adhesion between the product and the sealing plate 30 is large, the ventilation mechanism 9 in the first air inlet 6 and the second air inlet 7 can be opened in sequence, and the first air pump 13 and the third air pump 14 can continuously supply gas to the frame 22 to ensure that the product can be demolded smoothly.
