Description

Technical Field

[0001] This utility model relates to the field of flash trimming technology, specifically a device for trimming and collecting flash on plastic parts. Background Technology

[0002] Flash, also known as overflow, burrs, or imperfections, mostly occurs at the parting points of molds, such as the parting surface between the moving and stationary molds, the sliding parts of sliders, the gaps in inserts, and the gaps in ejector pin holes. Flash is largely caused by the failure of the mold or machine clamping force. Generally speaking, it is impossible for plastic parts to be completely free of flash due to various factors. During die forging, excess metal in the final forging die cavity flows into the flash groove, forming a ring of metal around the forging, which ensures that the metal fills the mold cavity. This ring must be sealed after die forging. Flash refers to the excess material that overflows into the mold parting line or the gaps in the ejector pins during the molding process and remains on the plastic part. It can be removed by polishing or grinding. This is due to low sealing accuracy between the male and female molds, excessive material, and leakage of excess material at weak sealing points. "Flash" also refers to the trimmed edge, a term used in binding.

[0003] Utility model patent CN215748157U discloses a flash removal device. This utility model includes a base, with a working base plate fixedly installed inside the base. A clamping seat is installed above the base, and a cylinder is installed above the clamping seat. A piston rod is installed inside the clamping seat, and a flash removal seat is installed below the piston rod. This utility model, by providing a working base plate, allows the workpiece to be clamped inside the adjusting seat during flash removal. An electric telescopic rod moves the clamping plate closer to the workpiece, limiting its position and facilitating flash removal. A slider slides outside the ball screw, allowing for easy adjustment of the grinding distance and direction. This design enhances practicality, ease of use, and structural stability and reliability.

[0004] While the aforementioned utility model can conveniently remove burrs, the plastic debris cut off during the burr removal process cannot be effectively collected. This debris, scattered in the air or on the ground, can affect workers. Debris on the ground may cause slips and injuries when stepped on, while airborne debris may affect workers' respiratory health. Therefore, we propose a device for trimming and collecting burrs from plastic parts. Utility Model Content

[0005] This invention provides a device for trimming and collecting burrs on plastic parts to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A device for trimming and collecting burrs on plastic parts includes a trimming mechanism, a protective mechanism sleeved on the outer left side of the trimming mechanism, and a fan fixedly installed on the top of the trimming mechanism. The protective mechanism includes a protective top plate, two protective side plates respectively fused to the front and rear surfaces of the protective top plate, and support strips respectively fused to the bottom of the left side surfaces of the two protective side plates. A connecting groove is provided in the middle of the upper surface of the protective top plate, and a connecting hole is provided at the upper right end of the front surface of one of the protective side plates. A protective rotating plate is hinged between the two support strips, and an auxiliary piece is fused to the top of the left side surface of the protective rotating plate.

[0007] As a preferred technical solution, the auxiliary piece is embedded with a magnet, and an iron sheet is embedded in the left side of the middle position of the upper surface of the protective top plate, and the auxiliary piece can be magnetically connected with the iron sheet.

[0008] This feature, through the magnetic attraction between the magnet and the iron plate, can quickly fix the protective rotating plate in a closed state, preventing the rotating plate from accidentally opening due to vibration during operation and improving the stability of the protection; at the same time, the magnetic connection facilitates quick opening and closing, making operation convenient.

[0009] As a preferred technical solution, the trimming mechanism includes a support base, a support plate welded to the right side of the upper surface of the support base, and a support top plate welded to the top of the front surface of the support plate. A workbench is installed in the middle of the upper surface of the support base. Collection boxes are slidably connected to the interior of both the front and rear sides of the upper surface of the support base. Mounting holes are opened on both the front and rear sides of the upper surface of the support top plate. A cutting mechanism is fixedly installed in the middle of the left side surface of the support top plate.

[0010] This design, with its mounting holes on the top plate providing a positioning base for the assembly of the protective mechanism, features a modular structure that facilitates assembly.

[0011] As a preferred technical solution, mounting posts are fused to both the front and rear sides of the right side of the lower surface of the protective top plate, and the mounting posts can be slidably inserted into the mounting holes.

[0012] This feature, through the sliding insertion of the mounting column and the mounting hole, enables a detachable connection between the protective mechanism and the maintenance mechanism. This ensures assembly stability and facilitates separate maintenance and replacement of either the protective mechanism or the maintenance mechanism in the future, thereby improving the flexibility of the equipment.

[0013] As a preferred technical solution, the fan is installed in the connecting groove area, and a rubber ventilation pipe is installed between the fan inlet and the connecting hole.

[0014] This feature allows the rubber ventilation duct to be flexible and adaptable to positional deviations between the fan and the connecting hole, ensuring a reliable seal on the exhaust path.

[0015] As a preferred technical solution, the upper surface of the support base is provided with collection grooves on both the front and rear sides for the collection box to slide and connect, and the upper surface of the support bar is located on the lower left side of the lower surface of the collection box.

[0016] This design, with its varying heights between the support bar and the collection box, prevents interference between the protective mechanism's support structure and the collection box's pull-out action, ensuring that both operate independently without affecting each other.

[0017] As a preferred technical solution, the outer surface of the auxiliary piece is provided with anti-slip texture, and the entire protective mechanism is made of transparent plastic material.

[0018] This feature, with its transparent plastic material, allows for direct observation of the internal repair work. Progress can be monitored without opening the protective mechanism, while maintaining the protective function, thus balancing safety and visibility.

[0019] As a preferred technical solution, the height of the protective side plate is greater than the overall height of the trimming mechanism, and a connecting channel is fixedly installed inside the connecting hole.

[0020] This feature enhances the structural stability of the exhaust path by creating a connecting channel within the connecting hole, preventing wear caused by direct contact between the ventilation pipe and the opening, extending the equipment's service life, and ensuring the accuracy of airflow guidance.

[0021] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, by setting up a protective mechanism, blocks the waste chips that fly everywhere with the cutting tool during the cutting process, preventing the waste chips from remaining in the air or on the ground and affecting the workers.

[0022] 2. This utility model, through the collection box and the fan, can concentrate the waste inside the trimming mechanism into the collection boxes on both sides by airflow, which is convenient for the waste to be recycled and centrally processed. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4 This embodiment provides a technical solution: A device for trimming and collecting burrs on plastic parts includes a trimming mechanism 100, a protective mechanism 200 sleeved on the left outer side of the trimming mechanism 100, and a fan 300 fixedly installed on the top of the trimming mechanism 100.

[0026] The protective mechanism 200 includes a protective top plate 210, two protective side plates 230 respectively fused to the front and rear surfaces of the protective top plate 210, and support bars 250 respectively fused to the bottom of the left side surfaces of the two protective side plates 230. A connecting groove 220 is provided in the middle of the upper surface of the protective top plate 210, and the right side of the connecting groove 220 extends to the right outer side of the protective top plate 210. A connecting hole 240 is provided at the upper right end of the front surface of one of the protective side plates 230. A protective rotating plate 260 is hinged between the two support bars 250, and an auxiliary piece 270 is fused to the top of the left side surface of the protective rotating plate 260. By covering the outside of the trimming mechanism 100 with the protective mechanism 200, the device can block the debris generated during the cutting process of the plastic part, preventing the debris from splashing and remaining in the air or accumulating on the bottom surface.

[0027] It should be added that the protective mechanism 200 is closely attached to the outside of the repair mechanism 100, and can completely cover the working area of ​​the repair mechanism 100.

[0028] Furthermore, such as Figure 3 As shown, the auxiliary piece 270 has a magnet embedded inside, and an iron sheet is embedded inside the left side of the middle position on the upper surface of the protective top plate 210. The auxiliary piece 270 can be magnetically connected to the iron sheet. The attraction between the magnet and the iron sheet allows the auxiliary piece 270 to be fixed to the top left side of the protective top plate 210.

[0029] Furthermore, such as Figure 2 As shown, the trimming mechanism 100 includes a support base 110, a support plate 150 welded to the right side of the upper surface of the support base 110, and a support top plate 160 welded to the top of the front surface of the support plate 150. A workbench 130 is installed in the middle of the upper surface of the support base 110. Collection boxes 120 are slidably connected to the interior of the front and rear sides of the upper surface of the support base 110. The collection boxes 120 can slide out from the front side of the support base 110. Mounting holes 170 are opened on the front and rear sides of the upper surface of the support top plate 160. A cutting mechanism 140 is fixedly installed in the middle of the left side surface of the support top plate 160. The cutting mechanism 140 is located above the workbench 130. Mounting columns 211 are fused to the front and rear sides of the right side of the lower surface of the protective top plate 210. The mounting columns 211 can be slidably inserted into the mounting holes 170, so that the protective mechanism 200 and the trimming mechanism 100 can be installed and disassembled conveniently and quickly.

[0030] In this embodiment, as Figure 3 As shown, the fan 300 is installed in the area of ​​the connecting groove 220. A rubber ventilation pipe is installed between the air inlet of the fan 300 and the connecting hole 240, and the air generated by the fan 300 is sent into the processing area through the ventilation pipe.

[0031] In this embodiment, as Figure 2 As shown, the upper surface of the support base 110 has collection grooves on both the front and rear sides for the collection box 120 to slide and connect. The upper surface of the support bar 250 is located on the lower left side of the lower surface of the collection box 120. The upper surface of the collection box 120, which is slidably connected in the collection groove, is flush with the upper surface of the support base 110, ensuring that the debris can smoothly enter the collection box 120.

[0032] In this embodiment, as Figure 3 As shown, the outer surface of the auxiliary piece 270 is provided with anti-slip texture, and the entire protective mechanism 200 is made of transparent plastic material, which makes it easy for users to observe the internal situation.

[0033] In this embodiment, as Figure 1 As shown, the height of the protective side plate 230 is greater than the overall height of the trimming mechanism 100. A connecting channel is fixedly installed inside the connecting hole 240. The connecting channel allows the ventilation pipe to pass through and be installed, preventing wear caused by direct contact between the ventilation pipe and the opening of the connecting hole 240.

[0034] It is worth noting that the structure and working principle of the fan 300 involved in this embodiment are as known to those skilled in the art, and will not be described in detail here. The structure and working principle of the cutting mechanism 140 involved in this embodiment are technologies already disclosed in the prior art, and will not be described in detail here.

[0035] In the specific use of the plastic part flash trimming and collection device of this embodiment, the protective top plate 210 is first placed above the supporting top plate 160, so that the mounting post 211 in the protective mechanism 200 is aligned with the mounting hole 170 opened on the supporting top plate 160. Then, the mounting post 211 on the protective top plate 210 is inserted into the mounting hole 170 to complete the installation of the protective mechanism 200. Then, the auxiliary plate 270 is manually turned to rotate the protective rotating plate 260 to the left around the support bar 250 to open it. After opening, the product to be processed can be placed on the workbench 130 to wait for processing. After the upper protective rotating plate 260 is installed, the auxiliary plate 270 is magnetically connected to the iron plate on the left side of the protective top plate 210. Then, wait for the cutting mechanism 140 to process the product. During the processing, the debris generated is blocked by the protective mechanism 200 and cannot fly around. After processing, the fan 300 is started first to blow away and clean the debris in the protective mechanism 200. Then, the fan 300 is turned off, the protective rotating plate 260 is opened, and the blown debris is further cleaned and sent into the collection box 120. The collection box 120 can be pulled to the left to be removed from the support base 110 for processing of the debris.
