Description

Technical Field

[0001] This utility model relates to the field of injection molding processing technology, and in particular to a device for removing burrs from injection molded parts. Background Technology

[0002] Injection molded parts refer to all kinds of injection molded products produced by injection molding machines, including various packaging, parts, etc. During the production and processing of injection molded parts, two molds need to be joined together for injection molding. During the injection molding process, burrs may be generated at the joint of the molds and at the injection port, which will affect the appearance of the injection molded parts.

[0003] To ensure the quality and aesthetics of injection molded parts, it is necessary to remove burrs from the edges of the injection molded parts. However, when using a burr removal device to grind and remove burrs from the injection molded parts, the debris generated during burr removal may adhere to and accumulate on the surface of the grinding wheel, affecting the contact between the grinding wheel and the burrs of the injection molded parts, resulting in uneven burr removal and even scratching the surface of the injection molded parts.

[0004] Therefore, how to design a deburring device for injection molded parts that can clean the deburring device is a technical problem that technicians need to solve. Utility Model Content

[0026] refer to Figures 1 to 8 A device for removing burrs from injection molded parts, comprising: The equipment body 1 and the cleaning mechanism 2 are included. The equipment body 1 includes a de-edge machine 101, a workbench 102 and a workpiece 105. The workbench 102 is installed inside the de-edge machine 101 and the workpiece 105 is placed on top of the workbench 102. The cleaning mechanism 2 includes an L-shaped base plate 201, an elastic scraper 207 for cleaning debris, and an adjusting push plate 209 for adjusting the cleaning force of the elastic scraper 207.

[0027] Specifically, the L-shaped base plate 201 has an arc-shaped frame 202 on its side wall, an elastic connecting plate 203 on the outer wall of the arc-shaped frame 202, a fixing plate 204 at one end of the elastic connecting plate 203, an arc-shaped base plate 205 on the side wall of the fixing plate 204, and an arc-shaped baffle 208 on the side wall of the L-shaped base plate 201.

[0028] Specifically, the arc-shaped base plate 205 has a groove 206 inside, and the inner wall of the groove 206 is provided with a plurality of elastic scrapers 207. The side wall of the L-shaped base plate 201 is provided with a side wall baffle 214, and one end of the side wall baffle 214 is provided with an elastic baffle 217. The outer wall of the fixed plate 204 is provided with an adjusting push plate 209.

[0029] Specifically, one end of the adjusting push plate 209 is provided with an adjusting plate 210, and the side wall baffle 214 is provided with an adjusting groove 215. The adjusting plate 210 is slidably fitted inside the adjusting groove 215.

[0030] Specifically, the top of the adjustment plate 210 is provided with a limiting block 211, the inside of the adjustment groove 215 is provided with a limiting groove 216, and the limiting block 211 is fixedly sleeved inside the limiting groove 216.

[0031] Specifically, one end of the adjusting plate 210 is provided with an elastic support plate 212, and the outer wall of the elastic support plate 212 is provided with a toggle plate 213.

[0032] Specifically, the L-shaped base plate 201 has mounting holes 218 inside, and mounting bolts 219 are installed inside the mounting holes 218.

[0033] Specifically, a drive motor 103 is provided at the bottom of the workbench 102, and a grinding wheel 104 is installed at the output end of the drive motor 103. The outer wall of the grinding wheel 104 is in contact with the outer wall of the workpiece 105.

[0034] Example 1: In this example, to address the problem of debris adhering to and accumulating on the grinding wheel 104 during deburring, thus affecting the deburring effect, the technical solution is as follows (see reference). Figures 1 to 8 The elastic connecting plate 203 is an arc-shaped elastic curved surface structure, made of metal, and has a certain degree of elasticity. The arc-shaped base plate 205 is C-shaped, and the elastic scraper 207 is S-shaped and made of metal. The elastic scraper 207 is linearly arrayed inside the groove 206. When the grinding wheel 104 cleans and removes the burrs on the workpiece 105, the elastic connecting plate 203 causes the surface of the elastic scraper 207 in the arc-shaped base plate 205 to adhere to the surface of the grinding wheel 104. Since the rotation direction of the elastic scraper 207 is opposite to that of the grinding wheel 104, the debris attached to and accumulated on the surface of the grinding wheel 104 can be scraped off while the grinding wheel 104 removes the burrs on the workpiece 105. This avoids the problem of uneven deburring effect caused by the grinding wheel 104 not adhering to and accumulating on the surface of the grinding wheel 104 and affecting the contact between the grinding wheel 104 and the burrs on the injection molded workpiece 105.

[0035] It should be noted that the arc-shaped baffle 208 is an arc-shaped plate made of metal. When cleaning the surface of the grinding wheel 104, the arc-shaped baffle 208 can block the flying debris and prevent it from splashing. The side wall baffle 214 is J-shaped, and the elastic baffle 217 is an arc-shaped elastic curved surface structure made of metal. When removing the edges of the injection molded parts, the side wall baffle 214 and the elastic baffle 217 can block the flying debris and facilitate the cleaning of the debris generated during edge removal.

[0036] Example 2: In this example, to solve the problem that the elastic scraper 207 is not strong enough to clean the debris adhering to the surface of the grinding wheel 104, the technical solution of this implementation is as follows, for reference. Figures 1 to 8The adjusting push plate 209 is an arc-shaped plate, and the adjusting clamping plate 210 is a plate. The adjusting push plate 209 and the adjusting clamping plate 210 are an integral structure and are made of metal. The elastic support plate 212 is an arc-shaped curved surface structure, made of metal, and has a certain degree of elasticity. The adjusting clamping plate 210 is set at both ends of the elastic support plate 212 and has a mirror symmetrical structure. When it is necessary to adjust the cleaning force of the elastic scraper 207 on the grinding wheel 104, the position of the adjusting clamping plate 210 in the adjusting groove 215 is adjusted. The adjusting push plate 209 is used to push the fixed plate 204, so that the fixed plate 204 moves around the elastic connecting plate 203, thereby adjusting the distance between the arc-shaped base plate 205 and the grinding wheel 104, thereby adjusting the cleaning force of the elastic scraper 207 on the grinding wheel 104 to ensure the cleaning effect of the elastic scraper 207 on the grinding wheel 104.

[0037] It should be noted that the limiting blocks 211 are arranged in a linear array on the top of the adjusting plate 210, the limiting slots 216 are set inside the adjusting groove 215, and the shape of the limiting blocks 211 matches the shape of the limiting slots 216. Under the outward support of the elastic support plate 212, the limiting blocks 211 can be fixedly sleeved in the limiting slots 216, which can limit the position of the adjusting plate 210.

[0038] Based on the above embodiments, when it is necessary to remove burrs from workpiece 105, the drive motor 103 is controlled to rotate the grinding wheel 104, causing the grinding wheel 104 to contact the burrs of workpiece 105 and remove them. At the same time, under the action of the elastic connecting plate 203, the surface of the elastic scraper 207 provided in the arc-shaped base plate 205 is made to adhere to the surface of the grinding wheel 104. Since the rotation direction of the elastic scraper 207 and the grinding wheel 104 is opposite, the debris attached to and accumulated on the surface of the grinding wheel 104 can be cleaned and scraped off while the grinding wheel 104 removes the burrs from the workpiece 105. This avoids the problem of uneven burr removal effect caused by the grinding wheel 104 adhering to and accumulating on the surface of the grinding wheel 104, which would affect the contact between the grinding wheel 104 and the burrs of the injection molded workpiece 105.

Furthermore, it is understood that the steps in the method of the present invention embodiments can be adjusted, combined, and deleted according to actual needs, and the structure in the device of the present invention embodiments can be combined, divided, and deleted according to actual needs.
