At present, plastic products are mainly manufactured by a mode of mould pressing (short for compression moulding, also called compression moulding); specifically, plastic is molded into a plastic product by heating and pressing in a closed mold cavity. In the compression molding process, the pressure of the raw material in the mold cavity is too large, and the mold separation force generated by the pressure is larger than the mold locking force, so that the working mold is forced to open, the raw material overflows from the working mold, and therefore, the flash is formed on the surface layer of the plastic product, and the flash is a common problem after the compression molding of the plastic product is finished.
In the traditional plastic product processing process, the flash is mainly removed in a manual mode; but because the work load of flash removal is quite large, the labor intensity of workers is high, and the production efficiency is low. In order to solve the problem, devices for automatically removing the flash of the plastic product are also available in the market at present, and the devices are mainly used for clamping the plastic product by adopting a clamping mechanism and then removing the flash of the clamped product by adopting a flash removing assembly. The deburring device 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 deburred at a time, and the product needs to be taken down from the clamping mechanism after deburring, the structure of the whole device is very complex and the efficiency is low.
In addition, current molding equipment is two material area ejection of compact, and the device of current automatic deburring plastic products overlap can't carry out the automation simultaneously to the moulded product on two drive belts and remove the overlap. The existing method is to collect the product which is output by the double-discharging belt after the molding of the molding equipment, then manually feed the product to the device which automatically removes the plastic product flash, and has low processing efficiency and high labor cost.

Detailed Description
As shown in fig. 1 to 3, the apparatus for deflashing a molded product provided by the present embodiment includes a feeding assembly 1 and a deflashing assembly 2. The feeding unit 1 feeds a molded product 100 having flash on the surface thereof after molding. The deburring component 2 is arranged on one side of the feeding component 1, and the deburring component 2 comprises a bearing plate 21, at least one group of elastic deburring pieces 22 and a bearing driving piece 23. The bearing plate 21 is disposed at one side of the feeding assembly 1, and the bearing plate 21 has a feeding hole 210. Each set of elastic edge-removing members 22 includes two edge-removing shafts elastically connected to the opposite inner sides of the feeding holes 210, and the distance between the two edge-removing shafts is smaller than the length of the molded product in the direction. The receiving driving member 23 is disposed at one side of the carrying plate 21 opposite to the feeding hole 210, and receives the molded product 100 conveyed by the feeding assembly 1 and drives the molded product 100 to move along the feeding hole 21. During trimming, the receiving driving member 23 drives the molded product 100 to move along the conveying hole, trimming shafts in at least one group of elastic trimming members 22 are compressed and clamp the molded product 100, and the trimming shafts bend and scrape the flash on the side wall of the molded product 100 along the opposite direction of the movement of the molded product.
In this embodiment, the receiving driving member 23 includes a receiving member 231 and a pushing member 232, the receiving member 231 and the material conveying hole 210 are disposed below the carrier plate 21 and move along the material conveying hole 210; the pushing element 232 and the receiving element 231 are disposed above the carrier plate 210. When the edges are removed, the receiving member 231 ascends along the feeding hole 210 and receives the molded product fed from the feeding unit 1, and the pushing member 232 moves downward and pushes the molded product 100 and the receiving member 231 along the feeding hole 210. However, the present invention is not limited thereto. In other embodiments, the receiving driving member may comprise only receiving elements and the receiving elements are capable of attracting or holding the molded product after receiving the molded product. Or in other embodiments, the receiving driving member can also receive the molded product below the material conveying hole, then drive the molded product to pass through the material conveying hole from bottom to top, and the trimming shaft scrapes the flash on the side wall of the molded product from top to bottom. Or in other embodiments, the receiving driving member may also be a material taking mechanical arm disposed above the material conveying hole, and the material taking mechanical arm moves downwards through the material conveying hole to absorb or grab the molded product, and then drives the molded product to pass through the material conveying hole from bottom to top.
In this embodiment, the receiving element 231 is a rotary lifting cylinder, and the pushing element 232 is a linear cylinder. However, the pushing member 232 has a pushing force. In other embodiments, the receiving member may also be a non-driving elastic member, such as a linear bearing. And in a normal state, the material receiving plate at the upper end of the linear bearing extends into the material conveying hole to wait for receiving a molded product, and after the molded product is received, the material pushing piece pushes the molded product downwards and extrudes the linear bearing. After the edge is removed, the pushing element returns, and the linear bearing drives the edge-removed product to ascend along the material conveying hole under the action of reverse restoring force.
The existing die pressing device has the advantages that double discharging belts synchronously discharge materials, die pressing products on the two discharging belts are opposite in direction, the direction of the die pressing product on one discharging belt is consistent with the direction of a subsequent punching film, and the difference between the die pressing product on the other discharging belt and the subsequent punching film is just 180 degrees. In the embodiment, the receiving element 231 is a rotary lifting cylinder, and for the molded product with the direction opposite to the direction of the subsequent punching die, the receiving element 231 adjusts the direction of the molded product 100 after the trimming of the molded product 100 is completed and outputs the product to the punching film 4, so as to ensure the product direction consistency of the molded product in the punching and pressure maintaining steps after the trimming. However, the present invention does not limit the angle of rotation of the adapter in any way. The rotation of the supporting member is to satisfy the consistency of the reverse direction of the molded product during punching, and in other embodiments, the rotation angle can be adjusted according to actual requirements. In the apparatus for deburring molded products of 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 the direction, the two deburring shafts are compressed when the molded product 100 passes through the feed delivery hole 210. And the edging axle that compresses can only centre gripping the lateral wall of moulded product 100 under the effect of resilience force, and when moulded product 100 moved down relative to the edging axle, the overlap on the lateral wall of moulded product 100 was bent and scraped from bottom to top to frictional force between the two. After the molded product 100 completely passes through the feed delivery hole 210, the trimming shaft is restored. The arrangement of the pusher 232 and the receiver 231 allows the molded product 100 to move downward against the friction between its side walls and the deburring shaft.
The deburring device for the molded product provided by the embodiment synchronously removes the side wall burrs of the molded product by using the dynamic friction force generated by the relative motion between the deburring shaft and the molded product 100 in the process of conveying the molded product 100. Compared with the existing special blade type flash removing device, the structure of the device is greatly simplified, and meanwhile, the efficiency is greatly improved by synchronous flash removal in the transmission process. Furthermore, the mode of removing the bent flash from bottom to top is not limited by the shape and the size of the flash on the side wall of the die pressing product, and even very large flash can be well removed. Preferably, the dynamic friction between the trimming shaft and the molded product can be adjusted by adjusting the compression stroke of the trimming shaft in actual production, such as using springs with different elastic coefficients or adjusting the distance between the two trimming shafts. The higher the dynamic friction, the better the deflashing, but the greater the power requirements of the same pusher or receiver.
In the embodiment, the deburring assembly 2 includes two sets of elastic deburring members 22, and four deburring shafts 221,222,223,224 are respectively elastically connected to four side walls of the feeding hole 210, and scrape burrs from four side walls of the molded product 100 when the molded product 100 passes through the feeding hole 210. However, the present invention is not limited thereto. In other embodiments, the edge-removing assembly may comprise only one set of elastic edge-removing members. The bearing piece is required to have a rotating function, after the flash is removed once, the bearing piece rotates the molded product by 180 degrees to turn the molded product to drive the molded product to move upwards, and the flash on the other group of side walls of the molded product is removed from top to bottom by the flash removing shaft.
For the case of the partition switch, for the isolating switches with different specifications and types, the length or width of the case will be different, so as to be compatible with the deburring process of various cases, in the embodiment, the supporting plate 21 includes a fixed plate 211 and a movable plate 212 movably connected to the fixed plate 211, a material transporting hole 210 is enclosed between the fixed plate 211 and the movable plate 212, and the movable plate 212 adjusts the distance between two deburring shafts 223,224 in the elastic deburring member 22 connected thereto. In the present embodiment, as shown in fig. 3, the fixed plate 211 has slide rails in two long sides thereof, the movable plate 212 is mounted in the slide rails to be slidably connected to the fixed plate 211, the trimming shaft 223 is mounted at one end of the sliding plate 212 close to the feeding hole 210, the trimming shaft 224 is disposed at the inner side of the short side of the fixed plate 211 opposite to the trimming shaft 223, and the trimming shafts 221 and 222 are disposed at the inner sides of the two long sides of the fixed plate 211, respectively. The movable plate 212 is adjusted during deburring to remove burrs of molded products with different lengths. However, the present invention is not limited thereto. In other embodiments, two movable plates may be disposed on the fixed plate and perpendicular to each other to adjust the length and width of the material feeding hole.
In this embodiment, each edge removing shaft is elastically connected to the inner wall of the material feeding hole 210 through at least one independent spring 225, the inner wall of the material feeding hole 210 is provided with a spring installation groove 213, one end of the spring 225 is fixed in the spring installation groove 213, and the other end is connected to the edge removing shaft. Preferably, as shown in fig. 3, each edging shaft is elastically connected to the bearing plate 21 by two or more independent springs 225 to ensure stability of the edging shaft in compression or rebound. However, the present invention is not limited to the elastic connection between the edge-removing shaft and the bearing plate. In other embodiments, a metal sheet with better elasticity can be used to realize the elastic connection when the elastic deformation of the edge removing shaft is not large.
In the present embodiment, as shown in fig. 1 and 2, the feeding assembly 1 includes a first driving belt 11, a second driving belt 12, a third driving belt 13, and a pushing cylinder 14. The first transmission belt 11 and the second transmission belt 12 are in parallel butt joint with the output end of the mould pressing device and are in independent transmission, and only one of the two transmission belts can convey the mould pressing products 100 to the third transmission belt 13 at any time during feeding. The third belt 13 is disposed at the output ends of the first belt 11 and the second belt 12, and receives and conveys the molded product 100 conveyed by the first belt 11 or the second belt 12. The pushing cylinder 14 is disposed at one side of the third belt 13, and pushes the molded product 100 on the third belt 13 to the receiving member 231 of the deflashing module 2.
Because the existing die pressing device is used for synchronously discharging materials in double discharging belts and the directions of products on the two discharging belts are completely opposite, in the embodiment, the first driving belt 11 and the second driving belt 12 of the feeding component 1 are respectively butted with the two discharging belts of the die pressing device. Since the first belt 11 and the second belt 12 are driven independently, the first belt 11 and the second belt 12 rotate simultaneously to receive the molded product 100 output from the molding device at the initial timing of the conveyance. After all the molded products from the molding device are conveyed to the first transmission belt 11 and the second transmission belt 12, the two transmission belts are stopped. Thereafter, the control system 7 of the molded product flashing processing apparatus separately activates the first belt 11, and the molded products 100 on the first belt 11 are separately conveyed onto the third belt 13. Specifically, the first motor 18 independently drives the first belt 11, the second motor 19 independently drives the second belt 12, and the third motor 110 independently drives the third belt 13.
In this embodiment, the feeding assembly 1 further includes a first incoming material detecting member 15 and a second incoming material detecting member 16, and the first incoming material detecting member 15 is disposed at an input end of the third driving belt 13. When the first feeding 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 is started and rapidly transmits the product to the position of the material pushing cylinder 14. When the second material feeding detection part 16 arranged opposite to the material pushing cylinder 14 detects that the product has reached the pushing range of the material pushing cylinder 14, the material pushing cylinder 14 starts to rapidly push the molded product to the receiving part 231 of the flash removing assembly 2, and then the material pushing cylinder 14 rapidly retreats.
When the molded product on the first belt 11 is completely processed, both the first belt 11 and the third belt 13 are stopped. The second conveyor belt 12 is activated and product on the second conveyor belt 12 is conveyed to the third conveyor belt 13. Similarly, when the first incoming material detecting member 15 on the third belt 13 detects that the molded product enters the third belt 13, the third belt is started and rapidly conveys the product to the position of the material pushing cylinder 14. When the second incoming material detecting element 16 on the material pushing cylinder 14 detects that the product has reached the pushing range of the material pushing cylinder 14, the material pushing cylinder 14 starts to rapidly push the molded product to the receiving element 231 of the deburring component 2. Since the direction of the molded product on the second transmission belt 12 is 180 degrees different from the direction 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 member 231 (rotary cylinder) while starting the second transmission belt 12, and after the flash removal of the product is completed, the receiving member 231 drives the product to rotate 180 degrees so that the direction of each product output from the flash removing assembly is the same.
In this embodiment, the first incoming material detecting member 15 and the second incoming material detecting member 16 are both detecting optical fibers. However, the present invention is not limited thereto. In other embodiments, the first incoming material detecting member may also be a pressure sensor disposed at an input end of the third belt.
In this embodiment, the pushing cylinder 14 is a track cylinder disposed above the third belt 13 and moving along a side where the deflashing module 2 is located. The material pushing cylinder 14 is connected with a material pushing plate 17 for pushing the molded product 100, and the rail-type material pushing cylinder drives the material pushing plate 17 to move, so that the molded product is pushed to the flash removing component 2.
In this embodiment, as shown in fig. 1 and fig. 2, the apparatus for processing flash of molded products further includes a material moving cylinder 3 and a punching die 4, the material moving cylinder 3 is disposed on one side of the receiving member 231, when the receiving member 231 drives the molded products to move to the bottom position along the material conveying hole 210, the material moving cylinder 3 pushes the molded products 100 to the punching die 4, and the punching die 4 presses down to remove flash of the inner hole of the molded products 100.
Further, the device for processing the flash of the die pressing product further comprises a pressure maintaining component 5 and a discharging component 6 which are arranged on the output side of the punching die 4. To the great mould pressing product of volume, the product after the pressurize subassembly 5 removes the overlap carries out the cooling water pressurize moulding, and ejection of compact subassembly 6 pushes away the product after the pressurize is moulded to stock chest 63. However, the present invention is not limited thereto. In other embodiments, when the molded product does not need to be subjected to pressure maintaining, the discharging assembly can be directly arranged at the output end of the punching die without arranging a pressure maintaining assembly. Or, for products which do not need pressure maintaining, the control system 7 can also control the pressure maintaining component 5 not to work, and the device has good compatibility.
In this embodiment, the molded product 100 punched by the punching die 4 is pushed to the lower side of the pressure maintaining assembly 5 by the punching and pushing cylinder 41. The discharging assembly 6 includes a plurality of discharging cylinders 61 disposed at one side of the pressure maintaining assembly 5, a discharging rail 62 and a storage tank 63.
In this embodiment, the mold pressing product deburring device further comprises a deburring collecting box 8 arranged below the deburring component 2, and the deburred burrs fall into the deburring collecting box 8. The flash collecting box 8 is provided with a flash outlet 81 at one side close to the storage tank 63.
Correspondingly, the embodiment also provides a molding device, which comprises a molding device and the molded product flash processing device provided by the embodiment. The feeding end of the feeding assembly 1 on the die pressing product flash processing device is connected with the discharging end of the die pressing device, and the flash removing assembly 2 removes the flash of the die pressing product 100 processed and formed by the die pressing device.

When the bearing driving piece drives the molded product to move along the conveying hole, the distance between the two edge removing shafts on the elastic edge removing piece is smaller than the width of the molded product in the direction, so that the molded product extrudes the two edge removing shafts when passing through the conveying hole, and the edge removing shafts clamp the molded product. Along with the movement of the molded product, the deburring shaft scrapes off the flash bending of the side wall of the molded product along the opposite direction. The trimming mode is high in efficiency, is not influenced by the shape and size of the burrs on the side wall of the die pressing product, and has a very good trimming effect.
