Description

Technical Field

[0001] The utility model relates to the technical field of injection mold processing, in particular to a deburring device for injection mold processing. Background Technique

[0002] An injection mold is a manufacturing process used to produce plastic products and is widely applied in various industries, including electronics, automotive, medical, consumer goods, etc.

[0003] After an injection mold processes a product formed by integral injection molding, the injection-molded finished product generally has mounting holes to achieve the later installation and fixation of the injection-molded finished product through screws and the mounting holes. However, burrs generally remain at the opening corner edges of the mounting holes on the injection-molded finished product, and deburring treatment is required.

[0004] Currently, the existing method for removing burrs at the opening corner edges of the mounting holes on the injection-molded finished product is generally that the operator first holds the injection-molded finished product with one hand, and then holds a handheld deburring tool with the other hand to grind and remove the burrs at the opening corner edges of the mounting holes. This method of manually holding the injection-molded finished product for grinding and deburring has low precision, and thus greatly reduces the quality of burr removal at the opening corner edges of the mounting holes on the injection-molded finished product;

[0005] In addition, generally, it is not possible to effectively clamp square-shaped or cylindrical injection-molded products. Summary of the Utility Model

[0006] The purpose of the utility model is to solve the above-mentioned drawbacks in the prior art and propose a deburring device for injection mold processing.

[0007] To achieve the above purpose, the utility model adopts the following technical scheme:

[0008] Design a deburring device for injection mold processing, including a workbench. Above the workbench, there are a first clamping group and a second clamping group. Both the first clamping group and the second clamping group are composed of a clamping cylinder, a moving frame, a double-threaded screw rod, a sliding clamping block, and an arc-shaped clamping plate. The clamping cylinder is arranged on the workbench. The moving frame is provided with a sliding guide seat and a sliding guide opening. A crank handle disc is arranged on the double-threaded screw rod;

[0009] The arc-shaped clamping plate is provided with a fastening screw groove and an anti-loosening elastic pad. The sliding clamping block is provided with a fastening screw pin;

[0010] The lower end of the workbench is provided with a support leg plate. A slag receiving box is arranged on the support leg plate. A slag dropping port is opened on the workbench.

[0011] Further, the guide sliding seat is fixedly arranged with the telescopic rod of the clamping cylinder, and the lower end surface of the guide sliding seat is in sliding contact with the workbench.

[0012] Further, the fastening screw pin passes through the sliding clamping block and is in threaded connection with the fastening screw groove, and the anti-loosening spring pad is integrally in a rectangular structure and is in extrusion contact with the sliding clamping block.

[0013] Further, a bearing is embedded in the moving frame, and a preset mounting hole of the bearing is fixedly sleeved with a double-threaded screw rod.

[0014] Further, the top view cross-section of the moving frame is in a U-shaped structure, there are two guide sliding openings that are symmetric front and back and are slidably sleeved with the sliding clamping block, and the guide sliding openings are rectangular long strip-shaped openings and run through the moving frame horizontally.

[0015] Further, the double-threaded screw rod is in threaded connection with the sliding clamping block, and there are two symmetrically arranged crank disks which are respectively arranged at both ends of the double-threaded screw rod.

[0016] Further, the upper end of the slag receiving box is in an open structure, and the size of the upper end opening of the slag receiving box is not less than the size of the top view surface of the slag dropping opening.

[0017] A deburring device for injection mold processing proposed by the present utility model has the following beneficial effects:

[0018] 1. By arranging an electric control type first clamping group and a second clamping group on the workbench, the present utility model can stably clamp the injection molding processing finished product, and then hold a handheld deburring tool to polish and deburr the burrs at the corner edge of the opening of the mounting hole, effectively avoiding the low precision of the manual method of holding the injection molding processing finished product for polishing and deburring, and thus greatly improving the quality of burr removal at the corner edge of the opening of the mounting hole on the injection molding processing finished product.

[0019] 2. By arranging a detachable arc-shaped clamping plate structure on both the first clamping group and the second clamping group, the present utility model can effectively clamp a square-shaped injection molding finished product or a cylindrical injection molding finished product respectively, and thus improve the clamping application range of the first clamping group and the second clamping group.

[0020] 3. By arranging a slag dropping opening on the workbench and a slag receiving box structure on the supporting leg plate, when polishing and deburring the burrs at the corner edge of the opening of the mounting hole on the stably clamped injection molding processing finished product, the burr impurities will pass through the mounting hole on the injection molding processing finished product and the slag dropping opening downward and be stored in the slag receiving box, avoiding the situation that the burr impurities directly fall on the ground and cause environmental pollution of the work area.

Specific embodiments

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0028] Referring to Figures 1-5 , a deburring device for injection mold processing, including a workbench 1, a first clamping group 3 and a second clamping group 4 are provided above the workbench 1. Both the first clamping group 3 and the second clamping group 4 are composed of a clamping cylinder 31, a moving frame 5, a double-threaded screw 6, a sliding clamping block 7, and an arc-shaped clamping plate 8. The clamping cylinder 31 is arranged on the workbench 1. The moving frame 5 is provided with a guide sliding seat 32 and a guide sliding opening 51. The double-threaded screw 6 is provided with a crank handle disk 61;

[0029] The arc-shaped clamping plate 8 is provided with a fastening screw groove 81 and an anti-loosening spring washer 82, and the sliding clamping block 7 is provided with a fastening pin 71;

[0030] The lower end of the workbench 1 is provided with a support leg plate 2, and the support leg plate 2 is provided with a slag receiving box 21. A slag discharge port 11 is opened on the workbench 1. The double-threaded screw 6 is a positive and reverse rotation threaded rod. When the double-threaded screw 6 rotates forward and backward, the simultaneous approach or separation of the sliding clamping blocks 7 on both sides and the arc-shaped clamping plate 8 can be realized, which is very convenient.

[0031] The hand-held deburring tool described in this patent is a prior art and is not drawn. At the same time, the cylindrical or square-shaped injection-molded finished product described in this patent is an injection-molded product integrally formed by an injection mold, which is a prior art and is not drawn.

[0032] The sliding guide seat 32 is fixedly arranged with the telescopic rod of the clamping cylinder 31. The lower end surface of the sliding guide seat 32 is in sliding contact with the workbench 1, achieving the effect of translational guiding and sliding of the moving frame 5.

[0033] The fastening pin 71 passes through the sliding clamping block 7 and is threadedly connected with the fastening screw groove 81. The anti-loosening elastic pad 82 is a rectangular structure as a whole and is in extrusion contact with the sliding clamping block 7. The anti-loosening elastic pad 82 is made of high-elastic polyurethane rubber. When the arc-shaped clamping plate 8 is installed, the anti-loosening elastic pad 82 will be extruded and generate a resilience force, and this resilience force acts on the fastening pin 71, improving its anti-loosening property.

[0034] A bearing 52 is embedded in the moving frame 5, and the preset installation hole of the bearing 52 is fixedly sleeved with the double-threaded screw rod 6, preventing the double-threaded screw rod 6 from slipping off the moving frame 5.

[0035] The top view cross-section of the moving frame 5 is a U-shaped structure. There are two symmetrically arranged front and rear sliding guide openings 51, which are slidably sleeved with the sliding clamping block 7. The sliding guide openings 51 are rectangular long-strip openings and penetrate the moving frame 5 horizontally, improving the guiding stability of the translational sliding of the sliding clamping block 7.

[0036] The double-threaded screw rod 6 is threadedly connected with the sliding clamping block 7. There are two symmetrically arranged crank disks 61, which are respectively arranged at both ends of the double-threaded screw rod 6. By rotating the crank disks 61 forward and backward, the double-threaded screw rod 6 is driven to rotate forward and backward. Through screw transmission, the two sliding clamping blocks 7 can be driven to translate close to or translate away from each other, achieving the adjustment effect, and can be adjusted and clamped for cylindrical or square-shaped injection-molded finished products with different external dimensions.

[0037] The upper end of the slag receiving box 21 is an open structure. The upper opening size of the slag receiving box 21 is not less than the top view size of the slag falling port 11, ensuring that all burr impurities fall into the slag receiving box 21.

[0038] Working mode: For example, if the injection-molded finished product to be clamped is cylindrical, place the cylindrical injection-molded finished product above the center of the workbench 1, and ensure that the mounting holes on the injection-molded finished product are in a vertically upward state. Then start the clamping cylinder 31. Drive the sliding clamping blocks 7 and the arc-shaped clamping plates 8 on both sides to translate horizontally and approach through the guide sliding seats 32 and the moving frame 5 on both sides. After the arc-shaped clamping plates 8 firmly clamp the cylindrical injection-molded finished product, stop the clamping cylinder 31. Then take a handheld deburring tool and polish the burrs at the corner edges of the opening of the mounting hole to remove the burrs, avoiding the low precision of the method of manually holding the injection-molded finished product for deburring, and thus greatly improving the quality of burr removal at the corner edges of the opening of the mounting hole on the injection-molded finished product.

[0039] Moreover, if the injection-molded finished product to be clamped is square, take an Allen wrench and insert it into the preset Allen slot on the fastening pin 71 and rotate counterclockwise to drive the fastening pin 71 to rotate counterclockwise out of the fastening groove 81 and remove it. At this time, the arc-shaped clamping plate 8 can be easily removed. Then start the clamping cylinder 31 to drive the sliding clamping blocks 7 on both sides to translate towards each other. After the sliding clamping blocks 7 firmly clamp the square injection-molded finished product, stop the clamping cylinder 31. Then take a handheld deburring tool and polish the burrs at the corner edges of the opening of the mounting hole to remove the burrs. It can effectively clamp the square injection-molded finished product or the cylindrical injection-molded finished product respectively, and thus improve the clamping application range of the first clamping group 3 and the second clamping group 4.

[0040] In addition, when polishing and removing the burrs at the corner edges of the opening of the mounting hole on the injection-molded finished product that is stably clamped, the burr impurities will pass downward through the mounting hole and the slag discharge port 11 on the injection-molded finished product and be stored in the slag receiving box 21, avoiding the situation that the burr impurities directly fall on the ground and cause environmental pollution of the work area.

[0041] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
