Abstract
Description
Technical Field
[0001] The present application relates to the field of mold technology, and in particular to a plastic part chip removal mold. Background Art
[0002] After injection molding, plastic parts generally produce lint on their surfaces. In high-voltage electrical appliances (such as automotive relays), plastic parts with lint are used during the assembly process. The lint can easily fall off and cause adverse electrical effects on the product, ultimately leading to product failure and affecting process use. Therefore, lint removal is an important process in the manufacturing industry.
[0003] like Figure 1 As shown, an existing plastic part 4 has a through hole 41 after molding, and the through hole 41 includes a large circle inner wall 411 and a small circle inner wall 412. When the through hole 41 is molded, a demolding line is easily generated, and plastic dander is easily generated at the demolding line. The traditional way to clean the dander is to clean it manually and use corresponding auxiliary tools to pick out the dander. This operation method is inefficient and requires a large labor cost. Summary of the Invention
[0004] In order to improve the low efficiency of existing dandruff removal methods, the purpose of this application is to provide a plastic part dandruff removal mold.
[0005] The present application provides a plastic part chip removal mold that adopts the following technical solution:
[0006] The cam is provided with a support plate for positioning the plastic part, and a positioning hole is provided at the center of the support plate. The upper mold is provided with an abutment head, and a chip removing assembly is provided on the side of the abutment head facing the positioning hole; the chip removing assembly comprises a punch part and a rotating part, the rotating part comprises a blade, a rotating shaft and a supporting piece, the supporting piece is fixed on the rotating shaft, the rotating shaft passes through the center of the punch part, and one end is rotatably connected to the abutment head, the supporting piece realizes support for the punch part, the blade is fixed on the rotating shaft and is located above the punch part; the lower mold is provided with a driving part at the projection area of the positioning hole, and when the abutment head drives the punch part and the rotating part to descend, the rotating shaft abuts on the driving part, and the driving part drives the rotating shaft to rotate.
[0007] By adopting the above technical solution, after the plastic part is placed on the receiving table, the through hole of the plastic part is located in the positioning hole at the same time, and the inner wall of the large circle and the inner wall of the small circle of the through hole are covered with hair scraps that need to be cleaned; during cleaning, the upper mold drives the abutment head to descend along the guide column, and at the same time, the punch part and the rotating part slide down into the through hole of the plastic part under the drive of abutment, and the punch part first abuts against the inner wall of the small circle, and the hair scraps on the inner wall of the small circle are scraped off by the downward pressure of the punch part at any time; after the punch part abuts, the rotating part abuts against the inner wall of the large circle at the same time, because the upper and lower heights of the inner wall of the large circle are lower than the upper and lower heights of the inner wall of the small circle, When the inner diameter of the inner wall of the large circle is larger than that of the inner wall of the small circle, the rotating part cannot directly scrape off the hair debris by directly pressing down; when the outer periphery of the rotating part abuts against the inner wall of the large circle, the end of the rotating shaft facing the lower mold is plugged into the driving part, and the driving part drives the rotating shaft to move synchronously by rotating. During the rotation process, the rotating shaft drives the rotating part to rotate along the inner wall of the large circle, thereby scraping off the hair debris on the inner wall of the large circle. By using this structure, the hair debris of this type of plastic parts can be quickly and automatically scraped off, and there is no need to clean it manually. The working efficiency is effectively improved and the labor input cost is reduced.
[0008] Optionally, the supporting platform includes a connecting plate, a buffer plate, a spring and a positioning column. The connecting plate is located below the buffer plate and is fixed to the lower mold. The positioning column is provided with a number of vertical connections to the connecting plate. The spring is sleeved on the positioning column. The buffer plate is synchronously sleeved on the positioning column and abuts against the spring. The positioning hole is opened on the buffer plate.
[0009] By adopting the above technical solution, when the plastic part is installed on the support, the buffer plate is used so that the abutment head drives the chip removal component to abut against the through hole of the plastic part. The plastic part is subjected to pressure and drives the buffer plate to press down at the same time. At this time, the buffer plate realizes buffering under the action of the spring, avoiding the plastic part from being broken due to the large local stress under the downward pressure of the abutment head. The use of this structure can effectively protect the product quality.
[0010] Optionally, a limiting member is further included, one end of which is fixedly connected to the connecting plate, and the other end of which abuts against the buffer plate to prevent the buffer plate from separating from the positioning column.
[0011] By adopting the above technical solution and utilizing the limiting member, the buffer plate will not separate from the positioning column during the buffering process, so that the process function can be achieved within the limited stroke, thereby preventing buffering failure.
[0012] Optionally, a support block is provided in the area of the connecting plate located at the positioning hole, and a receiving platform is provided on the side of the punch member facing the support block. When the abutment head drives the punch member and the rotating member to descend, the receiving platform abuts against the support block.
[0013] By adopting the above technical solution and utilizing the support block, the receiving platform can be limited by the support block during the downward pressing process of the punch part. This can prevent the chip removal component from failing to accurately fall into the through hole of the plastic part to achieve normal chip removal operation; and secondly, it can prevent the rotating shaft from causing a large impact force on the driving part when it abuts against the driving part due to a large stroke during the downward pressing process. The overall precise positioning effect can be achieved through the support block.
[0014] Optionally, there is a gap between the receiving platform and the supporting sheet.
[0015] By adopting the above technical solution, there is a gap between the receiving platform and the support plate, so that when the driving member drives the rotating shaft to rotate, the gap setting is used, and the support plate will not be subjected to obvious friction resistance during the synchronous rotation process, thereby avoiding affecting the normal rotation of the rotating shaft, allowing the blade to achieve normal rotation and produce the effect of removing dandruff.
[0016] Optionally, a first blanking trough is provided on the support block, the punch member is a hollow structure, and a second blanking trough is provided on the outer periphery, and the second blanking trough is communicated with the first blanking trough.
[0017] By adopting the above technical solution, the first blanking trough opened on the support block is used to facilitate the discharge of hair chips on the inner wall of the small circle on the plastic part. At the same time, the second blanking trough is used to facilitate the discharge of hair chips on the inner wall of the large circle on the plastic part. The second blanking trough is connected to the first blanking trough, so that the hair chips in the second blanking trough can be discharged to the outside along the first blanking trough. The overall design is exquisite and the chip removal effect is good.
[0018] Optionally, the support block and the positioning hole are both circular, and the outer diameter of the support block is smaller than the inner diameter of the positioning hole.
[0019] By adopting the above technical solution, the outer diameter of the support block is smaller than the inner diameter of the positioning hole, so that the shavings on the inner wall of the small circle on the plastic part can not only be discharged into the first blanking trough, but also can be discharged through the gap between the support block and the positioning hole, thereby increasing the chip removal space and achieving effective diversion.
[0020] Optionally, the rotating shaft and the driving member are both facing the first blanking chute, a block is provided at one end of the rotating shaft facing the driving member, and a square hole adapted to the block is provided on the driving member.
[0021] By adopting the above technical solution, the rotating shaft and the driving member are both facing the first blanking groove, so that the rotating shaft passes through the first blanking groove and accurately abuts against the driving member during the downward pressing process. When abutting, the square hole on the driving member limits the square on the rotating shaft, so that the driving member drives the rotating shaft to achieve normal rotation.
[0022] Optionally, there is a gap between the blade and the punch member and the abutment head respectively.
[0023] By adopting the above technical solution, there is a gap between the blade and the punch part and the abutment head respectively, so that when the blade removes the lint on the inner wall of the large circle of the plastic part, the rotation of the blade will not cause friction to the punch part and the abutment head, preventing impact damage or loud noise.
[0024] Optionally, the upper mold includes a sliding plate and a cylinder, the abutment head is installed on the sliding plate, and the cylinder is connected to the sliding plate to drive the sliding plate to slide up and down along the guide column.
[0025] By adopting the above technical solution, the cylinder is used to drive the sliding plate, and the sliding plate drives the abutment head to move up and down, so that the chip removal component can be conveniently controlled to realize the chip removal operation of the plastic parts. The process control is convenient, the structure is simple, and the application effect is good.
[0026] In summary, this application has at least one of the following beneficial effects:
[0027] 1. After the plastic part is placed on the receiving table, the through hole of the plastic part is located in the positioning hole at the same time. The inner walls of the large circle and the small circle of the through hole are covered with dander that need to be cleaned. During cleaning, the upper die drives the abutment head to descend along the guide column. At the same time, the punch part and the rotating part slide down into the through hole of the plastic part under the drive of abutment. The punch part first abuts against the inner wall of the small circle. The dander on the inner wall of the small circle is scraped off by the downward pressure of the punch part at any time. After the punch part abuts, the rotating part abuts against the inner wall of the large circle at the same time. Because the upper and lower heights of the inner wall of the large circle are lower than those of the inner wall of the small circle, and the inner diameter of the inner wall of the large circle is larger than that of the small circle, The inner diameter of the inner wall of the circle is small, so the rotating part cannot directly scrape off the dander by directly pressing down; when the outer periphery of the rotating part abuts against the inner wall of the large circle, the end of the rotating shaft facing the lower mold is plugged into the driving part, and the driving part drives the rotating shaft to move synchronously by rotating. During the rotation process, the rotating shaft drives the rotating part to rotate along the inner wall of the large circle, thereby scraping off the dander on the inner wall of the large circle. With this structure, the dander of the plastic part can be quickly and automatically scraped off, and there is no need to clean it manually, which effectively improves the working efficiency, reduces the labor input cost, and has great market promotion value;
[0028] 2. The support block allows the receiving platform to be positioned during the downward pressing of the punch. This prevents the chip removal assembly from being unable to accurately fall into the through-hole of the plastic part to achieve normal chip removal operation. It also prevents the large impact force caused by the shaft contacting the driver during the downward pressing process. The support block ensures precise positioning of the entire unit.
[0029] 3. The first blanking trough on the support block is used to facilitate the discharge of the hair scraps on the inner wall of the small circle on the plastic part. At the same time, the second blanking trough is used to facilitate the discharge of the hair scraps on the inner wall of the large circle on the plastic part. The second blanking trough is connected to the first blanking trough, so that the hair scraps in the second blanking trough can be discharged to the outside along the first blanking trough. The overall design is exquisite and the chip removal effect is good BRIEF DESCRIPTION OF THE DRAWINGS

The terms used herein are only for the purpose of describing specific embodiments and are not intended to limit this application.
[0040] In the description of the embodiments of this application, unless otherwise specified or limited, technical terms such as "installed," "connected," "connected," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, integration, or mechanical connections. Those skilled in the art will understand the specific meanings of these terms in the embodiments of this application based on specific circumstances.
[0041] A plastic part 4 chip removal mold, see Figure 2 and Figure 3 , including an upper mold 1 and a lower mold 2, which are connected by a guide column 3. The upper mold 1 and the lower mold 2 are both square structures. The guide columns 3 are respectively connected to the four corners of the square upper mold 1 and the square lower mold 2. The upper mold 1 includes a sliding plate 1225 and a cylinder 1226. The cylinder 1226 is fixed to the end of the four guide columns 3 away from the lower mold 2. The sliding plate 1225 is slidably connected to the column and is located at the lower part of the cylinder 1226. The driving end of the cylinder 1226 is connected to the sliding plate 1225. When the cylinder 1226 is extended or retracted, it drives the sliding plate 1225 to slide up and down along the guide column 3.
[0042] Specifically, the lower mold 2 is provided with a receiving platform 21, a positioning hole 211 is opened at the center of the receiving platform 21, a butt joint 11 is provided at the center of the sliding plate 1225, and a chip removal component 12 is provided on the side of the butt joint 11 facing the positioning hole 211. The receiving platform 21 includes a connecting plate 212, a buffer plate 213, a spring 215 and a positioning column 216. The positioning hole 211 is opened on the buffer plate 213, and the connecting plate 212 is located below the buffer plate 213 and is fixed by fastening bolts. Fixed on the lower mold 2, the positioning column 216 is provided with four vertically connected to the connecting plate 212 and distributed in a square array. The spring 215 adopts a linear specification spring 215 and is sleeved on the positioning column 216. The buffer plate 213 is synchronously sleeved on the positioning column 216 and abuts against the spring 215. The spring 215 is clamped between the buffer plate 213 and the connecting plate 212. When subjected to gravity, the buffer plate 213 can rise and fall along the positioning column 216 under the action of the spring 215.
[0043] In some embodiments, in order to prevent the buffer plate 213 from separating from the positioning column 216 during the buffering movement, so that it can realize the process function within the limited stroke and prevent buffering failure, in this embodiment, a limiting member 217 is also provided on the connecting plate 212. There are two limiting members 217, which are respectively located on the left and right sides of the buffer plate 213. One end of the limiting member 217 is fixedly connected to the connecting plate 212 by a fastening bolt, and the other end is in an "L" shape and abuts against the top surface of the buffer plate 213, which is used to limit the buffer plate 213 from separating from the positioning column 216.
[0044] See Figure 4 and Figure 5 The plastic part 4 is placed on the buffer part, and the buffer part is used to support the plastic part 4. The buffer part is provided with a plurality of positioning pins 214 for limiting the periphery of the plastic part 4. The through hole 41 of the plastic part 4 is located in the positioning hole 211. The chip removal assembly 12 includes a punch part 121 and a rotating part 122. The rotating part includes a blade 1221, a rotating shaft 1222 and a supporting piece 1224. The supporting piece 1224 is passed through the rotating shaft 1222 and is connected to the rotating shaft 122. 2 is fixedly connected, the support piece 1224 has a circular structure, one end of the rotating shaft 1222 passes through the center of the punch member 121 and is rotatably connected to the abutment head 11, the support piece 1224 abuts against the punch member 121, so that the punch member 121 can be supported by the support piece 1224, the blade 1221 has an arc-shaped structure, the center of which passes through the rotating shaft 1222 and is fixedly connected to the rotating shaft 1222, and the blade 1221 is located above the punch member 121.
[0045] See Figure 3 、 Figure 4 and Figure 5, the lower die 2 is provided with a driving member 22 in the projection area of the positioning hole 211. The driving member 22 is a motor. The fixed end of the motor is connected to the lower die 2, and the driving end faces the positioning hole 211. After the plastic part 4 is placed, the hair scraps on the inner wall 411 of the large circle and the inner wall 412 of the small circle at the through hole 41 are waiting to be cleaned. Specifically, the upper die 1 drives the abutment head 11 to descend along the guide column 3, and at the same time, the punch part 121 and the rotating part 122 slide into the through hole 41 of the plastic part 4 under the drive of the abutment. The punch part 121 first abuts against the inner wall 412 of the small circle, and the hair scraps on the inner wall 412 of the small circle are scraped off as the punch part 121 is pressed down at any time; after the abutment of the punch part 121 is completed, the rotating part 122 abuts against the inner wall 411 of the large circle at the same time.
[0046] It should be noted that the shavings on the inner wall 412 of the small circle are scraped off by directly pushing and pushing by the punch part 121. Because the upper and lower heights of the inner wall 411 of the large circle are lower than the upper and lower heights of the inner wall 412 of the small circle, and the inner diameter of the inner wall 411 of the large circle is larger than the inner diameter of the inner wall 412 of the small circle, the rotating part 122 cannot directly scrape off the shavings by directly pressing down.
[0047] When the outer periphery of the rotating part 122 abuts against the inner wall 411 of the large circle, the end of the rotating shaft 1222 facing the lower mold 2 is plugged into the driving part 22, and the driving part 22 drives the rotating shaft 1222 to move synchronously by rotating. During the rotation process, the rotating shaft 1222 drives the rotating part 122 to rotate along the inner wall 411 of the large circle, thereby scraping off the hair debris on the inner wall 411 of the large circle.
[0048] It should be noted that a support block 23 is also provided in the projection area of the connecting plate 212 located in the positioning hole 211, and a receiving platform 21 is provided on the side of the punch part 121 facing the support block 23. When the abutment head 11 drives the punch part 121 and the rotating part 122 to descend into the through hole 41 of the plastic part 4, the receiving platform 21 abuts on the support block 23 at the same time. By utilizing the support block 23, the receiving platform 21 can be limited by the support block 23 during the pressing process of the punch part 121. On the one hand, it prevents the chip removal component 12 from failing to accurately fall into the through hole 41 of the plastic part 4 to achieve normal chip removal operation; on the other hand, it prevents the rotating shaft 1222 from causing a large impact force on the driving part 22 when it abuts against the driving part 22 due to a large stroke during the pressing process. The overall precise positioning effect can be achieved through the support block 23.
[0049] In some embodiments, a first blanking trough 231 is provided on the support block 23, the punch part 121 is a hollow structure, and a second blanking trough 1211 is provided on the outer periphery. When the abutment head 11 drives the punch part 121 and the rotating part 122 to descend into the through hole 41 of the plastic part 4, the second blanking trough 1211 is connected with the first blanking trough 231. The first blanking trough 231 provided on the support block 23 is utilized to facilitate the discharge of hair chips on the inner wall 412 of the small circle on the plastic part 4. At the same time, the second blanking trough 1211 is utilized to facilitate the discharge of hair chips on the inner wall 411 of the large circle on the plastic part 4. The second blanking trough 1211 is connected with the first blanking trough 231, so that the hair chips in the second blanking trough 1211 can be discharged to the outside along the first blanking trough 231. The overall design is exquisite and the chip removal effect is good.
[0050] In some embodiments, the support block 23 and the positioning hole 211 are both circular, and the outer diameter of the support block 23 is smaller than the inner diameter of the positioning hole 211, so that the shavings on the inner wall 412 of the small circle on the plastic part 4 can not only be discharged into the first blanking trough 231, but also can be discharged through the gap between the support block 23 and the positioning hole 211, thereby increasing the chip removal space and achieving effective diversion.
[0051] In some embodiments, one end of the rotating shaft 1222 and the driving member 22 are both facing the first blanking trough 231, and a block 1223 is provided at the end of the rotating shaft 1222 facing the driving member 22. A square hole 221 adapted to the block 1223 is provided on the driving member 22, and the outer edge and the inner edge of the block 1223 are both chamfered.
[0052] It should be noted that in this embodiment, the driving member 22 is controlled to rotate. When the abutting head 11 drives the punch member 121 and the rotating member 122 to descend into the through hole 41 of the plastic part 4, the driving member 22 rotates in advance. When the block 1223 of the rotating shaft 1222 abuts the square hole 221 of the driving member 22, the early rotation of the driving member 22 can be utilized to facilitate the rapid insertion of the block 1223 of the rotating shaft 1222 into the square hole 221 of the driving member 22, achieving precise docking, and ultimately achieving the rotation of the rotating shaft 1222 by the driving member 22. Similarly, the extension and retraction of the cylinder 1226 is also controlled by the program. The action time of the cylinder 1226 and the driving member 22 is set by the program. When the chip removal operation on the plastic part 4 is completed, the program first controls the driving member 22 to stop, and then controls the cylinder 1226 to separate the chip removal assembly 12 from the through hole 41 of the plastic part 4.
[0053] In this embodiment, there is a gap between the receiving platform 21 and the support piece 1224, so that when the driving member 22 drives the rotating shaft 1222 to rotate, the gap setting is used to prevent the support piece 1224 from being subjected to significant frictional resistance during the synchronous rotation process, thereby avoiding affecting the normal rotation of the rotating shaft 1222, allowing the blade 1221 to rotate normally and simultaneously achieve the effect of removing lint. At the same time, there is also a gap between the blade 1221 and the punch member 121 and the abutment head 11. When the blade 1221 removes lint from the large circle inner wall 411 of the plastic part 4, the rotation of the blade 1221 does not cause friction on the punch member 121 and the abutment head 11, thereby preventing impact damage or loud noise.
[0054] The implementation principle of the embodiment of the present application is as follows: after the plastic part 4 is placed on the receiving platform 21, the through hole 41 of the plastic part 4 is simultaneously located in the positioning hole 211, and both the large circle inner wall 411 and the small circle inner wall 412 of the through hole 41 have hair scraps that need to be cleaned; during cleaning, the upper die 1 drives the abutment head 11 to descend along the guide column 3, and at the same time, the punch part 121 and the rotating part 122 slide down into the through hole 41 of the plastic part 4 under the drive of abutment, and the punch part 121 first abuts against the small circle inner wall 412, and the hair scraps on the small circle inner wall 412 are scraped off as the punch part 121 is pressed down at any time; after the punch part 121 completes the abutment, the rotating part 122 abuts against the large circle inner wall 412 at the same time. On the inner wall 411 of the circle, because the upper and lower heights of the inner wall 411 of the large circle are lower than the upper and lower heights of the inner wall 412 of the small circle, and the inner diameter of the inner wall 411 of the large circle is larger than the inner diameter of the inner wall 412 of the small circle, the rotating part 122 cannot directly scrape off the hair debris by directly pressing down; when the outer periphery of the rotating part 122 abuts against the inner wall 411 of the large circle, the end of the rotating shaft 1222 facing the lower mold 2 is connected with the driving part 22, and the driving part 22 drives the rotating shaft 1222 to move synchronously by rotating, and the rotating shaft 1222 drives the rotating part 122 to rotate along the inner wall 411 of the large circle during the rotation process, thereby scraping off the hair debris on the inner wall 411 of the large circle.
