Abstract

The present application relates to the technical field of die cutting processing auxiliary jig, specifically to an auxiliary hole opening jig for heat-conducting material, comprising: a storage box; a blanking plate arranged on the top of the storage box and having a blanking opening corresponding to the windowed area of the heat-conducting silica gel sheet, the blanking opening being in communication with the storage box; an ejection plate movably arranged on the upper side of the blanking plate; a top block arranged on the side of the ejection plate facing the blanking plate; a first air hole through-opening on the blanking plate; and a second air hole through-opening on the ejection plate. The first air hole and the second air hole are in communication when the ejection plate and the blanking plate are closed, so that the inside of the storage box and the outside atmosphere are kept in communication, thereby balancing the air pressure inside and outside the storage box. Thus, the back pressure formed due to the increased air pressure in the storage box is eliminated, and the waste heat-conducting silica gel sheet with light weight and thin thickness can be smoothly dropped into the storage box by its own gravity.

Description

Technical Field

[0001] This invention relates to the field of auxiliary fixtures for die-cutting processes, and more specifically to an auxiliary fixture for opening holes in thermally conductive materials. Background Technology

[0002] Thermally conductive silicone pads are widely used in control motherboards of electronic and electrical products, internal and external pads and feet of motors, automotive machinery, computer mainframes, laptops, and various materials requiring filling and heat dissipation modules. In practical applications, due to the uneven surfaces of electronic components, products are often designed with irregular shapes and windows, and high dimensional accuracy is required. The molding process for thermally conductive silicone pads often employs die-cutting; to meet the dimensional tolerances of the parts, precision molds are used for die-cutting.

[0003] In existing technologies, due to the characteristics of thermally conductive silicone (easily deformed and prone to overflowing under pressure, high hardness that can damage the die), mirror-finish die-cutting is often used. Waste material from the windowed area after die-cutting is mainly removed manually. Manually removing waste from one product typically takes 2-3 minutes, which is inefficient. Furthermore, the repeated handling, pressing, and ejection of waste material easily leads to defects such as deformation, crushing, wrinkles, scratches, and overflowing. These defects can recur, causing batch defects and high production costs.

[0004] To improve waste discharge efficiency, existing technologies, such as Chinese Patent Publication No. CN221435364U, disclose a lens through-hole waste discharge fixture, which includes a waste collection box, a lens positioning fixture, and a lens positioning fixture pressure plate. The lens positioning fixture has a positioning groove, and the inner side of the lens positioning fixture pressure plate has a boss with multiple perforated protrusions spaced apart on the boss. The lens positioning fixture is set on the upper end face of the waste collection box, and the positioning groove communicates with the cavity of the waste collection box. During waste discharge, the lens is placed in the positioning groove, and the lens positioning fixture pressure plate is placed on the lens positioning fixture. The perforated protrusions, corresponding to the through-hole positions, press out the waste, which falls into the waste collection box through the discharge hole for collection. The front end of the waste collection box has an opening, and a drawer extends into the waste collection box through the opening for emptying the collected waste.

[0005] However, in the aforementioned prior art, the waste collection box forms a closed space after the drawer is pushed in, without a dedicated ventilation structure. During the fall of waste, the air inside the collection box is compressed, increasing the internal air pressure and creating back pressure. Because the thermally conductive silicone sheet waste is lightweight and thin, its own weight is relatively small, and the back pressure is sufficient to overcome the weight of the waste, hindering its smooth fall. As a result, the waste may become stuck in the discharge hole or discharge channel, unable to enter the collection box. The accumulation of stuck waste can clog the discharge hole, preventing further waste from falling and necessitating a shutdown for cleaning, severely impacting the continuity and efficiency of waste removal operations.

[0006] To address the aforementioned problems, this invention proposes an auxiliary perforation fixture for thermally conductive materials. Summary of the Invention

[0007] (1) Technical problems to be solved The purpose of this invention is to overcome the shortcomings of existing waste collection fixtures, where the waste collection structure is closed, causing back pressure to be formed by the compression of air in the collection structure during the fall of waste. This results in the lightweight and thin thermal conductive silicone sheet waste being obstructed from falling, stuck in the through hole or the material drop channel, and requiring machine shutdown for cleaning. To meet practical needs, this invention provides an auxiliary opening fixture for thermal conductive materials to solve the above-mentioned technical problems.

[0008] (2) Technical solution To achieve the objectives of this invention, the technical solution adopted is as follows: An auxiliary perforation fixture for thermally conductive materials includes: a storage box; a discharge plate disposed on the top of the storage box for carrying a thermally conductive silicone sheet, wherein the discharge plate has a discharge port corresponding to the window area of ​​the thermally conductive silicone sheet, and the discharge port is connected to the storage box; a top plate movably disposed on the upper side of the discharge plate, wherein the top plate can be closed or opened with the discharge plate; a top block disposed on the side of the top plate facing the discharge plate and corresponding to the window area of ​​the thermally conductive silicone sheet; a first vent hole penetrating through the discharge plate; and a second vent hole penetrating through the top plate; when the top plate and the discharge plate are closed, the first vent hole and the second vent hole are connected to each other, allowing the interior of the storage box to communicate with the external atmosphere, thereby balancing the air pressure inside and outside the storage box and preventing back pressure from forming when waste material falls into the storage box due to increased air pressure inside the storage box.

[0009] Furthermore, the first vent and the second vent are positioned away from the material discharge port and the top block.

[0010] Furthermore, the outer contour of the top block is recessed inward relative to the edge of the thermally conductive silicone sheet window area, and the contour of the discharge port is extended outward relative to the edge of the thermally conductive silicone sheet window area.

[0011] Furthermore, the blanking plate is provided with a positioning groove, which is used to place a thermally conductive silicone sheet, and the blanking port is located in the positioning groove.

[0012] Furthermore, the lower surface of the blanking plate is provided with a countersunk hole communicating with the blanking opening, and the outline of the countersunk hole is outward relative to the edge of the blanking opening.

[0013] Furthermore, the edge of the positioning groove is provided with a tearing hand position, the two sides of the material dropping plate are provided with finger picking positions, and the position of the ejector plate corresponding to the finger picking position constitutes an operating part.

[0014] Furthermore, the ejector plate is hinged to the blanking plate via a hinge.

[0015] Furthermore, the hinge is a spring-loaded hinge, a first magnet is provided on the side of the ejector plate facing the blanking plate, and a second magnet is provided on the blanking plate, with the first magnet and the second magnet magnetically attracted to each other.

[0016] Furthermore, a receiving groove is provided on the side of the ejector plate away from the blanking plate, and a lifting plate is slidably connected in the receiving groove. The end of the top block away from the blanking plate extends through the ejector plate into the receiving groove and is fixedly connected to the lifting plate. The lifting plate can drive the top block to extend and retract relative to the ejector plate. An edge frame is fixedly connected to the inner wall of the receiving groove, and a guide post is fixedly connected between the edge frame and the bottom wall of the receiving groove. The lifting plate is slidably connected to the guide post.

[0017] Furthermore, the operating part has a receiving opening, and an operating block is disposed within the receiving opening. A transmission rod is fixedly connected between the operating block and the lifting plate. A clearance opening for the transmission rod to move is provided on the ejector plate. A third magnet is embedded on the upper surface of the lifting plate, and a fourth magnet is embedded on the lower surface of the edge frame. The third magnet and the fourth magnet are magnetically attracted to each other. When the lifting plate is at its highest position, the operating block protrudes from the ejector plate on the side away from the discharge plate, and the third magnet and the fourth magnet are attracted to each other, and the lifting plate is fixed relative to the ejector plate. When the lifting plate is at its lowest position, the operating block protrudes from the ejector plate on the side facing the discharge plate, and the third magnet and the fourth magnet are separated. In the state where the first magnet and the second magnet are attracted to each other, the lifting plate can slide relative to the ejector plate.

[0018] (3) Beneficial effects: A. In this invention, a first vent is provided on the discharge plate and a second vent is provided on the ejector plate. When the ejector plate and the discharge plate are closed, the first and second vents are connected, keeping the inside of the storage box connected to the outside atmosphere, thereby balancing the air pressure inside and outside the storage box. This eliminates the back pressure caused by the increased air pressure inside the storage box when the waste falls, allowing lightweight and thin thermally conductive silicone sheet waste to fall smoothly into the storage box under its own weight, preventing waste from getting stuck in the discharge port, eliminating the need to stop the machine for cleaning, and improving the continuity and efficiency of waste removal operations.

[0019] B. In this invention, by making the outer contour of the top block recess inward relative to the edge of the window area of ​​the thermally conductive silicone sheet, the contour of the discharge port expands outward relative to the edge of the window area, facilitating the smooth entry of the top block into the discharge port and leaving a gap between the waste material and the discharge port, reducing friction and promoting waste material descent. By providing a countersunk hole on the lower surface of the discharge plate that communicates with the discharge port, and the contour of the countersunk hole being larger than the contour of the discharge port, when the waste material is ejected and enters the space of the countersunk hole, it loses the constraint of the discharge port wall and falls more easily by gravity, further preventing jamming.

[0020] C. In this invention, by using a spring-loaded hinge and setting a first magnet and a second magnet that attract each other between the ejector plate and the discharge plate, during operation, after separating the first magnet and the second magnet, the spring-loaded hinge automatically springs the ejector plate open, which is convenient to operate, reduces operation steps, and improves waste discharge efficiency.

[0021] D. In this invention, by setting up a lifting plate and causing the lifting plate to extend and retract relative to the ejector plate, the top block can be extended during waste discharge, making its effective height greater than the effective thickness of the discharge port, forcing the waste material to sink directly into the hole and preventing waste material blockage; at the same time, the lifting plate can drive the top block to retract, avoiding interference between the top block and the discharge port, which would affect the opening and closing action of the ejector plate.

[0022] E. In this invention, the operating block is connected to the lifting plate via a transmission rod, allowing the operator to simultaneously operate the lifting plate while using the operating block to open and close the ejector plate. By setting a third and fourth magnet, the lifting plate and ejector plate can be relatively fixed, enabling both to perform closing actions simultaneously, completing the sequential action of ejector plate closing first, followed by ejector block extension. By setting a first and second magnet, the ejector plate and discharge plate can be relatively fixed, allowing the lifting plate to slide relative to the ejector plate when the third and fourth magnets are separated, completing the sequential action of ejector block retraction first, followed by ejector plate opening. This achieves sequential control of the ejector block extending after ejector plate closure and retracting before ejector plate opening, avoiding interference between the ejector block and discharge port during opening and closing. The entire operation is continuous and simple, requiring no additional power, thus improving the reliability and ease of operation of waste discharge. Attached Figure Description

[0025] The following is in conjunction with the appendix Figure 1-8 The present invention is further illustrated by the embodiments: Example 1 like Figures 1-3 As shown, this embodiment provides an auxiliary opening fixture for thermally conductive materials, including a storage box 1, a material dropping plate 2, an ejector plate 4, a top block 5, a first vent 202, and a second vent 401.

[0026] Storage box 1 is used to collect waste material discharged from the window area of ​​thermally conductive silicone sheet 3; a discharge plate 2 is disposed on the top of storage box 1 to support thermally conductive silicone sheet 3, and the discharge plate 2 has a discharge port 201 corresponding to the window area of ​​thermally conductive silicone sheet 3, the discharge port 201 being connected to storage box 1. Preferably, the discharge plate 2 and storage box 1 are detachably connected to facilitate the cleaning of waste material inside storage box 1. After the thermally conductive silicone sheet 3 is die-cut, the waste material in the window area falls into storage box 1 through discharge port 201.

[0027] The ejector plate 4 is movably disposed on the upper side of the discharge plate 2, and the ejector plate 4 can be closed or opened with the discharge plate 2; the top block 5 is disposed on the side of the ejector plate 4 facing the discharge plate 2, and corresponds to the window area of ​​the thermally conductive silicone sheet 3. When the ejector plate 4 is closed with the discharge plate 2, the top block 5 extends into the discharge port 201 and ejects the waste material in the window area.

[0028] The first vent 202 is formed through the material drop plate 2, and the second vent 401 is formed through the ejector plate 4. When the ejector plate 4 and the material drop plate 2 are closed, the first vent 202 and the second vent 401 are connected, allowing the inside of the storage box 1 to communicate with the outside atmosphere. This balances the air pressure inside and outside the storage box 1, preventing back pressure caused by increased air pressure inside the storage box 1 from hindering the waste from falling into the storage box 1. Thus, when the waste falls, the air inside the storage box 1 can be discharged into the atmosphere through the first vent 202 and the second vent 401 in sequence, and outside air can also smoothly enter the storage box 1, thereby balancing the air pressure inside and outside the storage box 1, eliminating back pressure caused by increased air pressure, and allowing the lightweight and thin thermally conductive silicone sheet 3 waste to fall smoothly into the storage box 1 by its own weight.

[0029] The first vent 202 and the second vent 401 are positioned away from the material discharge port 201 and the top block 5. This prevents waste material from clogging the first vent 202 and the second vent 401 or from affecting the movement of the top block 5, ensuring a continuous and effective air pressure balance.

[0030] The outer contour of the top block 5 is recessed inward relative to the edge of the window area of ​​the thermally conductive silicone sheet 3, while the contour of the discharge port 201 is extended outward relative to the edge of the window area of ​​the thermally conductive silicone sheet 3. This facilitates the smooth entry of the top block 5 into the discharge port 201, leaving a gap between the waste material and the discharge port 201 to reduce friction and promote waste material descent. Preferably, the height of the top block 5 is 1.5mm, the outer contour of the top block 5 is recessed inward by 0.5mm relative to the edge of the window area of ​​the thermally conductive silicone sheet 3, and the contour of the discharge port 201 is extended outward by 0.5mm relative to the edge of the window area of ​​the thermally conductive silicone sheet 3.

[0031] The material discharge plate 2 is provided with a positioning groove 203, which is used to place the thermally conductive silicone sheet 3, facilitating the positioning of the thermally conductive silicone sheet 3 and preventing the product from shifting during the waste discharge process. Preferably, the depth of the positioning groove 203 is 0.8mm. The material discharge port 201 is located within the positioning groove 203.

[0032] The lower surface of the discharge plate 2 has a countersunk hole 204 communicating with the discharge port 201. The outline of the countersunk hole 204 is wider than the edge of the discharge port 201. When the waste material is ejected and enters the space of the countersunk hole 204, it loses the constraint of the discharge port 201 and falls more easily by gravity, further avoiding jamming. Preferably, the depth of the countersunk hole 204 is 6mm.

[0033] The edge of the positioning groove 203 is provided with a tearing handle 205, which facilitates the operator to pick up and put down the thermally conductive silicone sheet 3. The two sides of the discharge plate 2 are provided with finger-picking positions 206, and the position on the ejector plate 4 corresponding to the finger-picking positions 206 constitutes an operating part 402, which facilitates the operator to operate the ejector plate 4. Preferably, the depth of the finger-picking position 206 is 5mm.

[0034] The working process of this embodiment is as follows: The thermally conductive silicone sheet 3 is placed into the positioning groove 203 of the discharge plate 2. The ejector plate 4 is closed to the discharge plate 2, and the top block 5 extends into the discharge port 201 to eject the waste material from the window area. The waste material passes through the discharge port 201 and enters the countersunk hole 204, finally falling into the storage box 1. Because the first vent 202 and the second vent 401 are connected, the air in the storage box 1 can be smoothly discharged, and the waste material's fall is not hindered by back pressure. After the waste discharge is completed, the ejector plate 4 is opened, and the thermally conductive silicone sheet 3 is removed.

[0035] Example 2 like Figure 4 As shown, in this embodiment, based on the first embodiment, the ejector plate 4 is hinged to the blanking plate 2 via a hinge 6, resulting in a simple structure and convenient opening and closing.

[0036] Furthermore, the hinge 6 is a spring-loaded hinge. A first magnet 7 is provided on the side of the ejector plate 4 facing the material drop plate 2, and a second magnet 8 is provided on the material drop plate 2. The first magnet 7 and the second magnet 8 are magnetically attracted to each other. When the ejector plate 4 and the material drop plate 2 are closed, the first magnet 7 and the second magnet 8 are attracted, locking the ejector plate 4 onto the material drop plate 2. When it needs to be opened, the operator separates the first magnet 7 and the second magnet 8 through the operating part 402, and the spring-loaded hinge 6 causes the ejector plate 4 to automatically spring back and open, facilitating quick and easy product retrieval.

[0037] The working process of this embodiment is as follows: The thermally conductive silicone sheet 3 is placed into the positioning groove 203 of the discharge plate 2. The ejector plate 4 is pressed down, causing it to flip downwards around the hinge 6 until the first magnet 7 and the second magnet 8 are attracted together, closing the ejector plate 4 and the discharge plate 2. The top block 5 extends into the discharge port 201 to eject the waste material from the window area. The waste material falls into the storage box 1 through the countersunk hole 204. After waste removal is completed, the first magnet 7 and the second magnet 8 are separated by the operating part 402, and the springback hinge 6 causes the ejector plate 4 to automatically spring back and open, allowing the thermally conductive silicone sheet 3 to be removed.

[0038] Example 3 like Figures 5-8 As shown, in this embodiment, based on embodiment two, a receiving groove 403 is provided on the side of the ejector plate 4 away from the discharge plate 2. A lifting plate 9 is slidably connected in the receiving groove 403. The end of the top block 5 away from the discharge plate 2 extends through the ejector plate 4 into the receiving groove 403 and is fixedly connected to the lifting plate 9. The lifting plate 9 can drive the top block 5 to extend and retract relative to the ejector plate 4. By setting the lifting plate 9 and driving the top block 5 to extend and retract relative to the ejector plate 4, the top block 5 can be extended during waste discharge, so that its effective height is greater than the effective thickness of the discharge port 201, forcing the waste material to directly sink into the hole 204 and preventing waste material blockage. At the same time, the lifting plate 9 can drive the top block 5 to retract, avoiding interference between the top block 5 and the discharge port 201, which would affect the opening and closing action of the ejector plate 4.

[0039] An edge frame 10 is fixedly connected to the inner wall of the receiving groove 403. A guide post 11 is fixedly connected between the edge frame 10 and the inner bottom wall of the receiving groove 403. The lifting plate 9 is slidably connected to the guide post 11 to ensure that the lifting plate 9 moves smoothly and improves reliability.

[0040] The operating part 402 has a receiving opening 404, and an operating block 12 is provided in the receiving opening 404. A transmission rod 13 is fixedly connected between the operating block 12 and the lifting plate 9. The ejector plate 4 has a clearance opening 405 for the transmission rod 13 to move. A third magnet 14 is embedded in the upper surface of the lifting plate 9, and a fourth magnet 15 is embedded in the lower surface of the edge frame 10. The third magnet 14 and the fourth magnet 15 are magnetically attracted. When the lifting plate 9 is in the highest position, the operating block 12 protrudes from the ejector plate 4 on the side away from the dropping plate 2, and the third magnet 14 and the fourth magnet 15 are attracted, and the lifting plate 9 is fixed relative to the ejector plate 4. When the lifting plate 9 is in the lowest position, the operating block 12 protrudes from the ejector plate 4 on the side facing the dropping plate 2, and the third magnet 14 and the fourth magnet 15 are separated. In the state where the first magnet 7 and the second magnet 8 are attracted, the lifting plate 9 can slide relative to the ejector plate 4. The operating block 12 is connected to the lifting plate 9 via the transmission rod 13, allowing the operator to simultaneously operate the lifting plate 9 while using the operating block 12 to open and close the ejector plate 4. By setting the third magnet 14 and the fourth magnet 15, the lifting plate 9 and the ejector plate 4 can be relatively fixed, allowing both to close simultaneously, completing the sequential action of the ejector plate 4 closing first, followed by the extension of the top block 5. By setting the first magnet 7 and the second magnet 8, the ejector plate 4 and the discharge plate 2 can be relatively fixed, allowing the lifting plate 9 to slide relative to the ejector plate 4 when the third magnet 14 and the fourth magnet 15 are separated, completing the sequential action of the top block 5 retracting first, followed by the opening of the ejector plate 4. This achieves the sequential control of the top block 5 extending after the ejector plate 4 closes and retracting before the ejector plate 4 opens, avoiding interference between the top block 5 and the discharge port 201 during opening and closing. The entire operation is continuous and simple, requiring no additional power, thus improving the reliability of waste discharge and operational convenience.

[0041] The working process of this embodiment is as follows: In the initial state, the ejector plate 4 is in the open position, the lifting plate 9 is in the highest position, the operating block 12 protrudes from the ejector plate 4 on the side away from the discharge plate 2, the third magnet 14 and the fourth magnet 15 are attracted to each other, and the lifting plate 9 is fixed relative to the ejector plate 4. At this time, the top block 5 is in the retracted state, and its end face will not interfere with the discharge port 201.

[0042] Place the thermally conductive silicone sheet 3 into the positioning groove 203 of the discharge plate 2. Press the operating block 12. Due to the attraction between the third magnet 14 and the fourth magnet 15, the lifting plate 9 and the ejector plate 4 are relatively fixed. The operating block 12 drives the ejector plate 4 to move downward together until the ejector plate 4 and the discharge plate 2 are closed. At this time, the first magnet 7 and the second magnet 8 are attracted, and the ejector plate 4 is fixed relative to the discharge plate 2.

[0043] Continue pressing the operating block 12. The operating block 12 overcomes the magnetic force between the third magnet 14 and the fourth magnet 15, causing the third magnet 14 and the fourth magnet 15 to separate. The lifting plate 9 is no longer fixed relative to the ejector plate 4, and the operating block 12 moves downward relative to the ejector plate 4, driving the lifting plate 9 to slide downward along the guide post 11 via the transmission rod 13. The lifting plate 9 drives the top block 5 to extend downward, and the top block 5 passes through the discharge port 201, pushing out the waste material from the window area. The waste material is pushed by the top block 5 and enters the countersunk hole 204, finally falling into the storage box 1. At this time, the lifting plate 9 is in its lowest position, and the operating block 12 protrudes from the side of the ejector plate 4 facing the discharge plate 2 and extends into the finger pick-up position 206 of the discharge plate 2 without interfering with the discharge plate 2.

[0044] After waste removal is completed, push the operating block 12 upward. Since the first magnet 7 and the second magnet 8 are attracted, the ejector plate 4 is fixed relative to the discharge plate 2. The operating block 12 first moves upward relative to the ejector plate 4, driving the lifting plate 9 to reset upward along the guide column 11 via the transmission rod 13. When the lifting plate 9 reaches its highest position, the third magnet 14 and the fourth magnet 15 are attracted, and the lifting plate 9 is fixed relative to the ejector plate 4 again, causing the top block 5 to retract. Continue pushing the operating block 12 upward; the operating block 12, through the lifting plate 9 and the edge frame 10, drives the ejector plate 4 upward together, separating the first magnet 7 from the second magnet 8. Under the action of the spring-back hinge 6, the ejector plate 4 automatically springs back and opens. At this time, the top block 5 has completely retracted and will not interfere with the discharge port 201.

[0045] Remove the drained thermal conductive silicone pad 3 and repeat the above steps for the next draining.

[0046] In one embodiment, a buffer is provided between the lifting plate 9 and the inner bottom wall of the receiving groove 403 to buffer the impact when the lifting plate 9 slides down to the lowest position. The buffer is preferably a polyurethane pad, a rubber pad, or a silicone pad.

Those skilled in the art can readily grasp the spirit of the present invention based on the above embodiments and make different extensions and variations, but as long as they do not depart from the spirit of the present invention, they are all within the protection scope of the present invention.
