Description

Technical Field

[0001] The invention relates to the field of plastic product processing, and in particular to a flash processing device for molded products and a molding equipment. Background Art

[0002] With the continuous development of technology, plastic products are widely used in people's daily life because of their light material and low cost; and because plastic products have very good insulation, the shell of power switches is also mostly made of plastic products. At present, plastic products are mainly made by compression molding (short for compression molding, also known as compression molding); specifically, plastic is formed into plastic products by heating and pressurizing in a closed mold cavity. During the compression molding process, the pressure of the raw material in the mold cavity is too large, and the mold separation force generated is greater than the clamping force, so the mold is forced to open, causing the raw material to overflow from the mold, thereby forming flash on the surface of the plastic product. Flash is a common problem of plastic products after the compression molding is completed.

[0003] In the traditional plastic product processing, flash is mainly removed manually; however, the workload of flash removal is quite large and the labor intensity of workers is high, resulting in low production efficiency. In order to solve this problem, some devices for automatically removing flash from plastic products are currently available on the market, which mainly use a clamping mechanism to clamp the plastic product, and then use a deburring component to deflash the clamped product. This deburring device not only has low clamping firmness and poor deburring effect; in addition, since the product needs to be placed in the clamping mechanism and only one product can be deflashed at a time, and the product needs to be removed from the clamping mechanism after deflashing, the structure of the entire device is very complicated and inefficient.

[0004] In addition, the existing molding equipment has dual discharge belts for discharging materials, and the existing device for automatically removing flash of plastic products cannot automatically convey and remove flash of the molded products on the two transmission belts at the same time. The existing practice is to first collect the products output by the dual discharge belts after molding by the molding equipment, and then manually load them to the device for automatically removing flash of plastic products, which has low processing efficiency and high labor costs. Summary of the invention

[0005] In order to overcome the problems of complex structure and low production efficiency of existing dynamic deburring devices, the present invention provides a new and efficient molded product flash processing device and molding equipment.

[0006] In order to achieve the above-mentioned purpose, the present invention provides a flash processing device for molded products, which includes a feeding component and a flash removal component. The feeding component conveys molded products with flash on the surface after molding. The flash removal component is arranged on one side of the feeding component, and the flash removal component includes a bearing plate, at least one group of elastic flash removal parts and a receiving drive component. The bearing plate is arranged on one side of the feeding component, and the bearing plate has a feeding hole. Each group of elastic flash removal parts includes two flash removal shafts elastically connected to the opposite inner sides of the feeding hole, and the spacing between the two flash removal shafts is less than the length of the molded product in this direction. The receiving drive component is arranged on one side of the bearing plate opposite to the feeding hole, receives the molded product conveyed by the feeding component and drives the molded product to move along the feeding hole. When flash removal is performed, the receiving drive component drives the molded product to move along the feeding hole, and the flash removal shafts in at least one group of elastic flash removal parts are compressed and clamp the molded product, and the flash removal shafts scrape off the flash bending of the side wall of the molded product in the opposite direction of the movement of the molded product.

[0007] According to one embodiment of the present invention, the receiving driving member includes a receiving member and a pushing member, the receiving member and the material feeding hole are arranged below the carrying plate and move up and down along the material feeding hole; the pushing member and the receiving member are arranged above the carrying plate;

[0008] When removing the edges, the receiving part rises along the feeding hole and receives the molded product conveyed by the feeding component, and the pushing part moves down and pushes the molded product and the receiving part along the feeding hole.

[0009] According to one embodiment of the present invention, the deburring assembly includes two groups of elastic deburring parts, and four deburring shafts are elastically connected to the four side walls of the feed hole respectively. When the molded product passes through the feed hole, the four deburring shafts simultaneously scrape off the flash of the four side walls of the molded product.

[0010] According to one embodiment of the present invention, the supporting plate includes a fixed plate and at least one movable plate movably connected to the fixed plate, a material feeding hole is formed between the fixed plate and the movable plate, and the movable plate adjusts the distance between two deburring shafts in the elastic deburring piece connected thereto.

[0011] According to one embodiment of the present invention, the receiving driving member is a rotary cylinder, and the receiving driving member adjusts the direction of the molded product after the edge removal of the molded product is completed;

[0012] Alternatively, when the edge removal assembly includes only one set of elastic edge removal members, after scraping off one set of side wall flash of the molded product, the molded product is rotated 180 degrees to scrape off the flash of another set of side walls of the molded product again.

[0013] According to one embodiment of the present invention, the feeding assembly comprises:

[0014] A first transmission belt and a second transmission belt connected to the output end of the molding equipment and arranged in parallel and independently driven, when feeding, only one of the two transmission belts conveys the molded product to the third transmission belt at any time;

[0015] A third transmission belt is arranged at the output ends of the first transmission belt and the second transmission belt, and receives and conveys the molded products conveyed by the first transmission belt or the second transmission belt;

[0016] The pushing member is arranged on one side of the third transmission belt, and pushes the molded product on the third transmission belt to the receiving driving member of the deburring assembly.

[0017] According to one embodiment of the present invention, the feeding assembly also includes a first incoming material detection member and a second incoming material detection member. The first incoming material detection member is arranged at the input end of the third transmission belt, and the third transmission belt is started when the first incoming material detection member detects that the product enters the third transmission belt; the second incoming material detection member is arranged opposite to the pushing member, and the pushing member is started when the second incoming material detection member detects that the molded product enters the pushing range of the pushing member.

[0018] According to one embodiment of the present invention, the flash processing device for molded products also includes a material transfer cylinder and a punching die. The material transfer cylinder is arranged on one side of the receiving driving member. When the receiving driving member drives the molded product to move along the material feeding hole to the bottom position, the material transfer cylinder pushes the molded product to the punching die, and the punching die is pressed down to remove the flash of the inner hole of the molded product.

[0019] According to one embodiment of the present invention, the molded product flash processing device also includes a pressure holding component and a discharge component arranged on the output side of the punching die. The pressure holding component performs cooling water pressure holding and shaping on the product after deburring, and the discharge component pushes the pressure-held and shaped product to the discharge trough.

[0020] The present invention also provides a molding device, which includes a molding device and the above-mentioned molded product flash processing device. The feeding end of the feeding component in the molded product flash processing device is connected to the discharging end of the molding device, and the flash removal component removes the flash of the molded product after the molding device is processed and formed.

[0021] In summary, in the molded product flash processing device and the molding equipment provided by the present invention, at least one group of elastic deburring parts is arranged on the inner side of the feed hole on the carrying plate in the deburring assembly. When the receiving driving part drives the molded product to move along the feed hole, since the distance between the two deburring shafts on the elastic deburring part is smaller than the width of the molded product in this direction, the molded product squeezes the two deburring shafts when passing through the feed hole, and the deburring shafts clamp the molded product. As the molded product moves, the deburring shafts scrape off the flash bends on the side walls of the molded product in the opposite direction. This deburring method is not only highly efficient but also unaffected by the shape and size of the flash on the side walls of the molded product, and has a very good deburring effect.

[0022] In order to make the above and other purposes, features and advantages of the present invention more obvious and easy to understand, preferred embodiments are given below and described in detail with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] like Figures 1 to 3 As shown, the molded product deburring device provided in this embodiment includes a feeding component 1 and a deburring component 2. The feeding component 1 conveys a molded product 100 having burrs on the surface after molding. The deburring component 2 is arranged on one side of the feeding component 1, and the deburring component 2 includes a supporting plate 21, at least one group of elastic deburring parts 22, and a receiving and driving component 23. The supporting plate 21 is arranged on one side of the feeding component 1, and a feeding hole 210 is provided on the supporting plate 21. Each group of elastic deburring parts 22 includes two deburring shafts elastically connected to the inner side of the feeding hole 210, and the spacing between the two deburring shafts is less than the length of the molded product in this direction. The receiving and driving component 23 is arranged on one side of the supporting plate 21 opposite to the feeding hole 210, receives the molded product 100 conveyed by the feeding component 1 and drives the molded product 100 to move along the feeding hole 21. When deburring, the driving member 23 drives the molded product 100 to move along the feed hole, and the deburring shafts in at least one group of elastic deburring members 22 are compressed and clamp the molded product 100. The deburring shafts scrape off the flash bends on the side walls of the molded product 100 in the opposite direction of the movement of the molded product.

[0028] In this embodiment, the receiving drive member 23 includes a receiving member 231 and a pushing member 232. The receiving member 231 is arranged below the carrier plate 21 relative to the feeding hole 210 and moves along the feeding hole 210; the pushing member 232 is arranged above the carrier plate 210 relative to the receiving member 231. When trimming, the receiving member 231 rises along the feeding hole 210 and receives the molded product conveyed by the feeding assembly 1, and the pushing member 232 moves down and pushes the molded product 100 and the receiving member 231 along the feeding hole 210. However, the present invention does not make any limitation to this. In other embodiments, the receiving drive member may only include the receiving member and the receiving member can absorb or fix the molded product after receiving the molded product. Or in other embodiments, the receiving drive member can also receive the molded product below the feeding hole, and then drive the molded product to pass through the feeding hole from bottom to top, and the trimming shaft scrapes off the flash of the side wall of the molded product from top to bottom. Alternatively, in other embodiments, the receiving drive member may also be a material picking robot arm disposed above the material feeding hole. The material picking robot arm moves downward through the material feeding hole to absorb or grab the molded product, and then drives the molded product to pass through the material feeding hole from bottom to top.

[0029] In this embodiment, the receiving member 231 is a rotary lifting cylinder, and the pushing member 232 is a linear cylinder. However, since the pushing member 232 itself has a driving force. In other embodiments, the receiving member can also be an elastic member without driving force, such as a linear bearing. Under normal conditions, the receiving plate at the upper end of the linear bearing extends into the feed hole to wait for the molded product to be received. After receiving the molded product, the pushing member pushes the molded product downward and squeezes the linear bearing. After the edge removal is completed, the pushing member retreats, and the linear bearing drives the edge-removed product to rise along the feed hole under the action of the reverse restoring force.

[0030] The existing molding device has two discharge belts that discharge materials synchronously, and the directions of the molded products on the two discharge belts are completely opposite. The direction of the molded products on one discharge belt is consistent with the direction of the subsequent punching film, while the products on the other belt are exactly 180 degrees different. In this embodiment, the receiving part 231 is a rotating lifting cylinder. For molded products whose direction is opposite to the direction of the subsequent punching die, the receiving part 231 adjusts the direction of the molded product 100 after the molded product 100 is trimmed, and then outputs it to the punching film 4, ensuring the consistency of the product direction of the molded product in the punching and holding steps after the trimming is completed. However, the present invention does not impose any limitation on the angle of rotation of the receiving part. The rotation of the receiving part is to meet the consistency of the reverse direction of the molded product during punching. In other embodiments, the rotation angle can be adjusted according to actual needs. In the molded product deburring device provided in this embodiment, since the distance between the two deburring shafts of the elastic deburring member 22 is smaller than the length of the molded product 100 in this direction, the two deburring shafts will be compressed when the molded product 100 passes through the feed hole 210. The compressed deburring shaft will only clamp the side wall of the molded product 100 under the action of the rebound force. When the molded product 100 moves downward relative to the deburring shaft, the friction between the two will bend and scrape off the flash on the side wall of the molded product 100 from bottom to top. After the molded product 100 completely passes through the feed hole 210, the deburring shaft is restored. The arrangement of the pushing member 232 and the receiving member 231 enables the molded product 100 to overcome the friction between its side wall and the deburring shaft and move downward.

[0031] The molded product deburring device provided in this embodiment utilizes the dynamic friction force generated by the relative movement between the deburring shaft and the molded product 100 during the transmission of the molded product 100 to synchronously remove the flash of the side wall of the molded product. Compared with the existing dedicated blade-type flash removal device, it not only greatly simplifies the structure of the device, but also greatly improves the efficiency of the synchronous flash removal during the transmission process. Furthermore, the bottom-up bending type flash removal method is not limited by the shape and size of the flash on the side wall of the molded product, and even very large flash can be well removed. Preferably, in actual production, the dynamic friction force between the deburring shaft and the molded product can also be adjusted by adjusting the compression stroke of the deburring shaft, such as using springs with different elastic coefficients or adjusting the distance between the two deburring shafts. The greater the dynamic friction force, the better the deburring effect, but the power demand of the same pusher or receiving member will also be greater.

[0032] In this embodiment, the deburring assembly 2 includes two groups of elastic deburring parts 22, and four deburring shafts 221, 222, 223, and 224 are elastically connected to the four side walls of the feed hole 210 respectively. When the molded product 100 passes through the feed hole 210, the four deburring shafts simultaneously scrape off the flash of the four side walls of the molded product 100. However, the present invention does not impose any limitation on this. In other embodiments, the deburring assembly may also include only one group of elastic deburring parts. In this case, the receiving part is required to have a rotation function. After one deburring is completed, the receiving part rotates the molded product 180 degrees to reverse the direction and then drives the molded product to move upward, and the deburring shaft removes the flash on the other group of side walls of the molded product from top to bottom.

[0033] For isolating switch housings, for isolating switches of different specifications and types, the length or width of the housing will be different. In order to be compatible with the deburring processing of various housings, in this embodiment, the carrier plate 21 includes a fixed plate 211 and a movable plate 212 movably connected to the fixed plate 211. The fixed plate 211 and the movable plate 212 form a material feeding hole 210. The movable plate 212 adjusts the distance between the two deburring shafts 223 and 224 in the elastic deburring member 22 connected thereto. In this embodiment, as Figure 3 As shown, the two long sides of the fixed plate 211 are provided with slide rails, the movable plate 212 is installed in the slide rails to slide and connect the fixed plate 211, the deburring shaft 223 is installed at one end of the sliding plate 212 close to the feeding hole 210, the deburring shaft 224 is arranged on the inner side of the short side of the fixed plate 211 opposite to the deburring shaft 223, and the deburring shafts 221 and 222 are respectively arranged on the inner side of the two long sides of the fixed plate 211. During the deburring process, the movable plate 212 is adjusted to achieve the deburring of molded products of different lengths. However, the present invention does not make any limitation to this. In other embodiments, two movable plates may be provided on the fixed plate and the two movable plates may be perpendicular to each other to achieve the adjustable length and width of the feeding hole.

[0034] In this embodiment, each trimming shaft is elastically connected to the inner wall of the feeding hole 210 through at least one independent spring 225. The inner wall of the feeding hole 210 is provided with a spring mounting groove 213. One end of the spring 225 is fixed in the spring mounting groove 213, and the other end is connected to the trimming shaft. Figure 3 As shown, each deburring shaft is elastically connected to the support plate 21 through more than two independent springs 225 to ensure the stability of compression or rebound of the deburring shaft. However, the present invention does not impose any limitation on the elastic connection between the deburring shaft and the support plate. In other embodiments, when the elastic deformation of the deburring shaft is not large, a metal sheet with good elasticity can also be used to achieve elastic connection.

[0035] In this embodiment, if Figure 1 and Figure 2As shown, the feeding assembly 1 includes a first transmission belt 11, a second transmission belt 12, a third transmission belt 13 and a push cylinder 14. The first transmission belt 11 and the second transmission belt 12 are parallelly connected to the output end of the molding device and the two are independently driven. During feeding, only one of the two transmission belts conveys the molded product 100 to the third transmission belt 13 at any time. The third transmission belt 13 is arranged at the output end of the first transmission belt 11 and the second transmission belt 12, and receives and conveys the molded product 100 conveyed by the first transmission belt 11 or the second transmission belt 12. The push cylinder 14 is arranged on one side of the third transmission belt 13, and pushes the molded product 100 on the third transmission belt 13 to the receiving part 231 of the deburring assembly 2.

[0036] Since the existing molding device has two discharge belts that discharge synchronously and the directions of the products on the two discharge belts are completely opposite, in this embodiment, the first transmission belt 11 and the second transmission belt 12 of the feeding assembly 1 are respectively connected to the two discharge belts of the molding device. Since the first transmission belt 11 and the second transmission belt 12 are independently driven, the first transmission belt 11 and the second transmission belt 12 are set to rotate simultaneously at the initial moment during transmission to receive the molded products 100 output by the molding device. After all the molded products from the molding device are transported to the first transmission belt 11 and the second transmission belt 12, the two transmission belts are stopped. Afterwards, the control system 7 of the molded product flash processing device starts the first transmission belt 11 alone, and the molded products 100 on the first transmission belt 11 are transported to the third transmission belt 13 alone. Specifically, the first motor 18 independently drives the first transmission belt 11, the second motor 19 independently drives the second transmission belt 12, and the third motor 110 independently drives the third transmission belt 13.

[0037] In this embodiment, the feeding assembly 1 further includes a first incoming material detection member 15 and a second incoming material detection member 16, and the first incoming material detection member 15 is arranged at the input end of the third transmission belt 13. When the first incoming material detection member 15 on the third transmission belt 13 detects that the molded product enters the third transmission belt 13, the third transmission belt 13 starts and quickly conveys the product to the position where the push cylinder 14 is located. When the second incoming material detection member 16 arranged opposite to the push cylinder 14 detects that the product has reached the pushing range of the push cylinder 14, the push cylinder 14 starts to quickly push the molded product to the receiving member 231 of the deburring assembly 2, and then the push cylinder 14 quickly retreats.

[0038] When all the molded products on the first conveyor belt 11 have been processed, the first conveyor belt 11 and the third conveyor belt 13 are stopped. The second conveyor belt 12 is started, and the products on the second conveyor belt 12 are conveyed to the third conveyor belt 13. Similarly, when the first incoming material detection member 15 on the third conveyor belt 13 detects that the molded product has entered the third conveyor belt 13, the third conveyor belt is started and the product is quickly conveyed to the position of the push cylinder 14. When the second incoming material detection member 16 on the push cylinder 14 detects that the product has reached the pushing range of the push cylinder 14, the push cylinder 14 is started to quickly push the molded product to the receiving member 231 of the deflashing assembly 2. Since the direction of the molded product on the second transmission belt 12 is 180 degrees different from that of the molded product on the first transmission belt 11, the control system 7 of the molded product flash processing device adjusts the execution action of the receiving part 231 (rotating cylinder) while starting the second transmission belt 12. After the flash of the product is removed, the receiving part 231 drives the product to rotate 180 degrees so that the direction of each product output from the de-burring component is the same.

[0039] In this embodiment, the first incoming material detection member 15 and the second incoming material detection member 16 are both detection optical fibers. However, the present invention does not make any limitation to this. In other embodiments, the first incoming material detection member may also be a pressure sensor disposed at the input end of the third transmission belt.

[0040] In this embodiment, the push cylinder 14 is a track-type cylinder disposed above the third transmission belt 13 and moving along the side where the deflashing assembly 2 is located. A push plate 17 for pushing the molded product 100 is connected to the push cylinder 14, and the track-type push cylinder drives the push plate 17 to move, thereby pushing the molded product to the deflashing assembly 2.

[0041] In this embodiment, if Figure 1 and Figure 2 As shown, the molded product flash processing device also includes a material moving cylinder 3 and a punching die 4. The material moving cylinder 3 is arranged on one side of the receiving part 231. When the receiving part 231 drives the molded product to move along the feed hole 210 to the bottom position, the material moving cylinder 3 pushes the molded product 100 to the punching die 4, and the punching die 4 presses down to remove the flash of the inner hole of the molded product 100.

[0042] Furthermore, the flash processing device for molded products also includes a pressure-holding component 5 and a discharge component 6 arranged on the output side of the punching die 4. For molded products with larger volumes, the pressure-holding component 5 performs cooling water pressure-holding shaping on the product after deburring, and the discharge component 6 pushes the pressure-held and shaped product to the storage tank 63. However, the present invention does not impose any limitation on this. In other embodiments, when the molded product does not need to be pressure-held, the discharge component can be directly arranged at the output end of the punching die without the need for a pressure-holding component. Alternatively, for products that do not require pressure-holding, the control system 7 can also control the pressure-holding component 5 to not work, and the device has good compatibility.

[0043] In this embodiment, the molded product 100 after punching by the punching die 4 is pushed to the bottom of the pressure holding assembly 5 by the punching push cylinder 41. The discharge assembly 6 includes a plurality of discharge cylinders 61, a discharge track 62 and a storage tank 63 arranged on one side of the pressure holding assembly 5.

[0044] In this embodiment, the molded product deburring device further comprises a deburring collecting box 8 disposed below the deburring assembly 2, and the removed deburring falls into the deburring collecting box 8. On the side close to the storage tank 63, the deburring collecting box 8 has a deburring outlet 81.

[0045] Correspondingly, this embodiment also provides a molding device, which includes a molding device and a molded product flash processing device provided in this embodiment. The feeding end of the feeding component 1 on the molded product flash processing device is connected to the discharging end of the molding device, and the flash removal component 2 removes the flash of the molded product 100 after being processed and formed by the molding device.

[0046] In summary, in the molded product flash processing device and the molding equipment provided by the present invention, at least one group of elastic deburring parts is arranged on the inner side of the feed hole on the carrying plate in the deburring assembly. When the receiving driving part drives the molded product to move along the feed hole, since the distance between the two deburring shafts on the elastic deburring part is smaller than the width of the molded product in this direction, the molded product squeezes the two deburring shafts when passing through the feed hole, and the deburring shafts clamp the molded product. As the molded product moves, the deburring shafts scrape off the flash bends on the side walls of the molded product in the opposite direction. This deburring method is not only highly efficient but also unaffected by the shape and size of the flash on the side walls of the molded product, and has a very good deburring effect.

[0047] Although the present invention has been disclosed as above by the preferred embodiment, it is not intended to limit the present invention. Anyone familiar with this technology can make slight changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope of protection required by the claims.
