Description

Technical Field

[0001] This utility model relates to the field of deburring technology for automotive parts, specifically a device for cleaning burrs from plastic molds for automotive parts. Background Technology

[0002] During the production of automotive parts plastic molds, burrs are easily generated due to factors such as mold closing clearance, material flowability, and machining precision. This not only affects the appearance and assembly accuracy of the parts but may also cause problems such as jamming in subsequent processes. Burr removal equipment is a key piece of equipment for solving this problem.

[0003] In existing deburring devices, to fix different plastic automotive parts, a clamping mechanism (for fixing thicker and heavier parts) and an adsorption structure (for fixing thinner parts) are usually set up. However, in order to protect the suction holes in the adsorption structure when switching from the adsorption structure to the clamping mechanism, the existing technology usually uses bolts to install protective plates. However, this protection method is relatively cumbersome, which reduces the switching efficiency. Therefore, a new structure is needed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a burr removal device for plastic molds of automotive parts, so as to solve the problems mentioned in the background art. To solve the above technical problems, this utility model is achieved through the following technical solution: This utility model relates to a burr removal device for plastic molds of automotive parts, comprising: A movable deburring assembly includes a worktable, an L-shaped plate, a first cylinder, and an electric grinder. The L-shaped plate is movably connected to the worktable, the first cylinder is fixedly connected to the L-shaped plate, and the electric grinder is fixedly connected to the bottom of the first cylinder. The fixing assembly includes an electric hydraulic cylinder, a clamping plate, a sealing plate, a disc, and a suction hole. The electric hydraulic cylinder is fixedly connected to both ends of the worktable. The clamping plate is fixedly connected to the side of the electric hydraulic cylinder. The sealing plate is fixedly connected to the bottom of the clamping plate. The disc is fixedly installed in the middle of the worktable. The suction hole is opened at the top of the disc. The sealing plate is movably connected to the top of the disc.

[0005] Furthermore, the fixing assembly also includes a receiving pipe and an air pump, with one end of the receiving pipe fixedly connected to the bottom of the disc, and the other end of the receiving pipe fixedly connected to the air pump.

[0006] Furthermore, the fixing assembly also includes a T-shaped shaft, which is fixedly connected to the bottom of the electric hydraulic cylinder and movably connected to the worktable.

[0007] Furthermore, the cross-sectional area of ​​the sealing plate is larger than the cross-sectional area of ​​the disk.

[0008] Furthermore, the movable deburring assembly also includes a second cylinder, one end of which is fixedly connected to the worktable, and the other end of which is fixedly connected to an L-shaped plate.

[0009] Furthermore, it also includes a quick adjustment assembly, which includes a rectangular block, a locking groove, a vertical plate, and a columnar rod. The rectangular block is fixedly connected to the side of the electric hydraulic cylinder, and a locking groove is formed in the rectangular block. The vertical plates are fixedly connected to both ends of the worktable, and the columnar rod is movably inserted through the vertical plate.

[0010] Furthermore, the quick adjustment assembly also includes a limiting ring and a spring, with the limiting ring fixedly connected to the outer side of the cylindrical rod and the spring movably sleeved on the outer side of the cylindrical rod.

[0011] Furthermore, the quick adjustment assembly also includes a pull plate, which is fixedly connected to the side of the cylindrical rod.

[0012] This utility model has the following beneficial effects: This invention fixes the sealing plate to the bottom of the clamping plate. When the electric hydraulic cylinder drives the clamping plate to rotate and switch to the clamping state, the sealing plate can rotate synchronously and cover the suction hole on the disc. There is no need to install a protective plate with bolts. When switching to the adsorption state, the sealing plate moves away with the clamping plate and directly exposes the suction hole. This eliminates the tedious steps of bolt removal and installation, greatly shortens the switching time between the adsorption structure and the clamping mechanism, and improves the operating efficiency.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0018] Please see Figure 1-4 As shown, this utility model is a burr removal device for plastic molds of automotive parts, comprising: The movable deburring assembly includes a worktable 101, an L-shaped plate 102, a first cylinder 103, and an electric grinder 104. The L-shaped plate 102 is movably connected to the worktable 101, the first cylinder 103 is fixedly connected to the L-shaped plate 102, and the electric grinder 104 is fixedly connected to the bottom of the first cylinder 103. The fixing assembly includes an electric hydraulic cylinder 201, a clamping plate 202, a sealing plate 203, a disc 204, and a suction hole 205. The electric hydraulic cylinder 201 is fixedly connected to both ends of the worktable 101. The clamping plate 202 is fixedly connected to the side of the electric hydraulic cylinder 201. The sealing plate 203 is fixedly connected to the bottom of the clamping plate 202. The disc 204 is fixedly installed in the middle of the worktable 101. The suction hole 205 is opened at the top of the disc 204. The top of the disc 204 is movably connected to the sealing plate 203. The fixing assembly also includes a receiving pipe 206 and a suction pump 207. The bottom end of the disc 204 is fixedly connected to one end of the receiving pipe 206. The other end of the receiving pipe 206 is fixedly connected to the suction pump 207. The fixing assembly also includes a T-shaped shaft 208. The bottom of the electric hydraulic cylinder 201 is fixedly connected to the T-shaped shaft 208. The T-shaped shaft 208 is movably connected to the worktable 101. The L-shaped plate 102 ensures the installation of the first cylinder 103. The first cylinder 103 ensures the electric grinder 104 can contact and grind the automotive parts. The grinding disc connected to the electric grinder 104 rotates to grind the automotive parts. The electric hydraulic cylinder 201 ensures that the clamping plates 202 at both ends can hold some automotive parts (thicker and heavier parts). The suction hole 205 on the disc 204 allows for the suction of other automotive parts (thinner parts). The suction pump 207 generates negative pressure on the disc 204 through the receiving pipe 206, thereby achieving the adsorption effect. The T-shaped shaft 208 provides a guarantee for the electric hydraulic cylinder 201 to drive the clamping plate 202 to rotate. Since the sealing plate 203 is fixedly connected to the bottom of the clamping plate 202, the sealing plate 203 can rotate with the clamping plate 202, thereby achieving the sealing and release of the suction hole 205, thus protecting the suction hole 205 when the clamping plate 202 clamps the automotive parts.

[0019] The cross-sectional area of ​​the sealing plate 203 is larger than that of the disc 204; The dimensions of the aforementioned components ensure complete coverage of the suction hole 205.

[0020] The movable deburring assembly also includes a second cylinder 105, one end of which is fixedly connected to the worktable 101, and the other end of which is fixedly connected to an L-shaped plate 102. The second cylinder 105 is configured to push the L-shaped plate 102 to move, thereby enabling the electric grinder 104 to be displaced, thus achieving the grinding and deburring of different areas of the automotive parts.

[0021] It also includes a quick-adjustment assembly, which includes a rectangular block 301, a locking groove 302, a vertical plate 303, and a columnar rod 304. The rectangular block 301 is fixedly connected to the side of the electric hydraulic cylinder 201. The locking groove 302 is opened in the rectangular block 301. The vertical plate 303 is fixedly connected to both ends of the worktable 101. The columnar rod 304 is movably inserted in the vertical plate 303. One end of the columnar rod 304 is movably connected to the locking groove 302. The quick-adjustment assembly also includes a limiting ring 305 and a spring 306. The limiting ring 305 is fixedly connected to the outside of the columnar rod 304. The spring 306 is movably sleeved on the outside of the columnar rod 304. The rectangular block 301 provides a guarantee for the opening of the locking groove 302, and the vertical plate 303 provides a guarantee for the movable connection of the column rod 304. The limiting ring 305 and the vertical plate 303 work together to limit the spring 306, so that the spring 306 has the force to push one end of the column rod 304 into the locking groove 302, thereby realizing the rapid locking after the electric hydraulic cylinder 201 is rotated and adjusted.

[0022] The quick-adjustment assembly also includes a pull plate 307, and the pull plate 307 is fixedly connected to the side of the column rod 304; The pull plate 307 is designed to make it easy for users to pull the column rod 304.

[0023] Working principle: The deburring process in the adsorption and fixing mode begins with the pull plate 307 pulling the cylindrical rod 304, compressing the spring 306 to disengage the cylindrical rod 304 from the locking groove 302. The electric hydraulic cylinder 201 rotates, causing the clamping plate 202 and sealing plate 203 to move away from the area of ​​the disc 204. The pull plate 307 is then released, and the spring 306 returns to its original position, pushing the cylindrical rod 304 to complete the fixing. Subsequently, a thinner automotive part plastic mold is placed on the disc 204. Then, the suction pump 207 is activated, creating negative pressure inside the disc 204 through the receiving pipe 206, utilizing suction... The part is held in place by the suction hole 205. Then, the second cylinder 105 is activated, pushing the L-shaped plate 102 horizontally on the worktable 101. This adjusts the electric grinder 104 to the area above the part where burrs need to be removed. Next, the first cylinder 103 is activated, pushing the electric grinder 104 downwards to contact the burr area of ​​the part. Simultaneously, the electric grinder 104 is activated, and the grinding disc rotates to remove the burrs. During this process, the horizontal position can be adjusted using the second cylinder 105 to achieve complete deburring. Finally, the electric grinder 104 is turned off, and the first cylinder 103 causes it to rise and reset. Close the suction pump 207 and remove the cleaned parts; in the deburring process under clamping and fixing mode, pull the pull plate 307 to rotate the electric hydraulic cylinder 201 in the opposite direction, driving the clamping plate 202 and the sealing plate 203 to rotate above the disc 204, so that the sealing plate 203 completely covers the disc 204 (blocking the suction hole 205). Release the pull plate 307 to allow the cylindrical rod 304 to be locked into the locking groove 302. Place the thicker and heavier automotive part plastic mold in the clamping area of ​​the worktable 101 (between the two clamping plates 202), and start the electric hydraulic cylinders at both ends. Cylinder 201 pushes clamping plate 202 to move towards the center until the part is clamped. The second cylinder 105 pushes L-shaped plate 102 to move, aligning electric grinder 104 with the burr position of the part. The first cylinder 103 is activated to lower electric grinder 104 to contact the burr and start cleaning. The second cylinder 105 is used to adjust the horizontal position to ensure that all burrs are removed. The electric grinder 104 is turned off, and the first cylinder 103 drives it to rise. The electric hydraulic cylinder 201 drives clamping plate 202 to reset and release the part, and the cleaned part is removed.
