Description

Technical Field

[0001] This utility model relates to the field of compression molding processing, specifically to a device for removing burrs from compression molded parts. Background Technology

[0002] In the field of compression molding, during the molding process, excess flash is easily generated on the edges of the compressed parts due to factors such as mold clearance and material flowability. These flashes not only affect the appearance accuracy of the compressed parts but may also cause difficulties in subsequent assembly, so they must be removed.

[0003] A search revealed a plastic product trimming machine (publication number CN210453418U), which relates to the field of plastic processing technology. The cutting machine includes a base with a rotatable support mechanism. One side of the support mechanism has a clamping mechanism, and the other side has a lifting and lateral-moving cutting mechanism. This invention achieves the adjustment and switching of the cutting position of the plastic product through the cooperation of the rotatable support mechanism and the lifting and lateral-moving cutting mechanism. The support mechanism is kept stable by anti-slip components, and the clamping mechanism secures the plastic product placed on the support mechanism. This invention is reasonably designed, flexible in operation, and improves both cutting accuracy and efficiency. The cutting mechanism in the aforementioned patent lacks precise positioning marks for its lateral movement adjustment, making it difficult for operators to intuitively control the adjustment distance of the cutting position. The cutting accuracy is easily affected by operating experience, making it difficult to meet the requirements for trimming the flash of high-precision compression molded parts.

[0004] Therefore, it is necessary to invent a device for removing flash from compression molded parts to solve the above problems. Utility Model Content

[0017] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0018] This utility model provides, for example Figure 1-4The device for removing flash from a compression molded part includes a base plate 1. A first support plate 2 is fixedly installed on the left side of the top of the base plate 1. A horizontal plate 3 is fixedly connected to the top of the first support plate 2. An electric telescopic rod 4 is fixedly installed on the top of the horizontal plate 3. The bottom end of the electric telescopic rod 4 passes through the horizontal plate 3 and extends to the outside of the horizontal plate 3. An upper fixed plate 5 is fixedly connected to the bottom end of the electric telescopic rod 4. An L-shaped fixed plate 6 is fixedly installed on the top of the base plate 1 and directly below the upper fixed plate 5 via a support column. A second support plate 7 is fixedly connected to the right side of the top of the base plate 1. A movable plate 8 is slidably connected to the front of the second support plate 7. An adjustment mechanism 9 is provided on the top of the movable plate 8. A sliding block 10 is slidably connected to the movable plate 8 and fixedly connected to the adjustment mechanism 9. A limiting mechanism 11 that works in conjunction with the adjustment mechanism 9 is fixedly installed on the right side of the top of the movable plate 8. An electric push cylinder 14 is fixedly connected between the bottom of the movable plate 8 and the top of the base plate 1. Both the electric telescopic rod 4 and the electric push cylinder 14 adopt existing technologies; A rotating motor 12 is fixedly mounted on the bottom of the sliding block 10 via a bracket, and a circular cutting blade 13 is fixedly connected to the output shaft of the rotating motor 12. The rotating motor 12 is connected to an external power source via a power cord; The adjustment mechanism 9 includes a mounting block 91, which is fixedly connected to the left side of the top of the movable plate 8. A lead screw 92 is rotatably connected to one side of the mounting block 91. A threaded block 93 is threadedly connected to the surface of the lead screw 92. The bottom of the threaded block 93 is fixedly connected to the top of the sliding block 10. The threaded block 93 has internal threads that mate with the lead screw 92. A support bearing 94 is provided at the right end of the surface of the lead screw 92. The support bearing 94 is fixedly connected to the movable plate 8. A rotating disk 95 is fixedly installed at the right end of the lead screw 92. The lead screw 92 is supported by the support bearing 94, and the user can rotate the lead screw 92 by rotating the turntable 95; A scale plate 15 is fixedly installed on the front of the movable plate 8, a support block 16 is fixedly connected to one side of the sliding block 10, and a marker rod 17 is fixedly installed on the top of the support block 16. The scale plate 15 and the pointer 17 facilitate the operator to control the moving distance of the sliding block 10 and adjust the working position of the circular cutting blade 13. The limiting mechanism 11 includes a mounting plate 111, the bottom of which is fixedly connected to the top of the movable plate 8. A spring telescopic rod 112 is fixedly installed on the bottom inner side of the mounting plate 111, and a limiting block 113 is fixedly connected to the bottom end of the spring telescopic rod 112. The limiting block 113 is arc-shaped, and the lower part of the limiting block 113 contacts the lead screw 92. The limiting block 113 is squeezed by the elastic force of the spring telescopic rod 112, so that the limiting block 113 squeezes the lead screw, preventing the lead screw 92 from rotating and improving its stability during use.

[0019] The working principle of this practical application is as follows: First, place the molded part to be processed on the horizontal surface of the L-shaped fixing plate 6. Then, activate the electric telescopic rod 4 according to the thickness of the molded part. The electric telescopic rod 4 drives the upper fixing plate 5 to move downward until the upper fixing plate 5 is in close contact with the top of the molded part, thus completing the clamping and fixing of the molded part. At this time, the vertical plate of the L-shaped fixing plate 6 can position one side of the molded part to prevent the molded part from shifting laterally, thus adapting to the fixing requirements of molded parts of different widths. Based on the lateral position of the flash on the compression molded part, rotate the rotating disk 95. The rotating disk 95 drives the lead screw 92 to rotate under the support of the mounting block 91 and the support bearing 94. The threaded block 93 on the surface of the lead screw 92 moves along the axial direction of the lead screw 92, thereby driving the sliding block 10 to slide laterally along the slide rail of the moving plate 8. When the sliding block 10 moves, the support block 16 simultaneously drives the pointer 17 to move along the scale plate 15. The operator can accurately control the moving distance of the sliding block 10 by pointing the pointer 17 to the value on the scale plate 15, until the circular cutting blade 13 is aligned with the flash cutting position. During this process, the limiting block 113 is pushed to separate the limiting block 113 from the lead screw 92. After the adjustment is completed, the limiting block 113 is released. The spring telescopic rod 112 of the limiting mechanism 11 always pushes the limiting block 113 to fit against the surface of the lead screw 92, so as to prevent the lead screw 92 from rotating due to vibration and to ensure the stability of the cutting position. The rotating motor 12 drives the circular cutting blade 13 to rotate at high speed; then the electric push cylinder 14 is activated, and the electric push cylinder 14 pushes the moving plate 8 to move downward along the slide rail of the second support plate 7. The moving plate 8 drives the high-speed rotating circular cutting blade 13 to gradually approach the flash of the molded part until the circular cutting blade 13 contacts the flash and completes the cutting.
