Problems solved by technology

Among these burrs, some burrs located on the edge of the protruding part of the product are easier to handle, while the injection holes are generally located in the recessed part of the product, which leads to the following two problems in manual processing: on the one hand, the space of the recessed part is narrow, which makes it difficult to remove the knife And it is easy to damage other parts of the product, which increases the scrap rate; on the other hand, it is difficult to completely remove the burr from the injection hole, and its root remains on the product, which reduces the product quality

Embodiment 1

[0020] A device for removing burrs from injection molding holes of plastic decorative parts of automobiles, comprising a housing 1 fixedly mounted on the frame of a manipulator for taking out products, the bottom of the housing 1 corresponding to the injection hole burrs 2 is provided with a The hole burr 2 protrudes into the opening. The casing 1 is provided with a cutting mechanism 3 for cutting the injection hole burr 2. The casing 1 is provided with a grinding mechanism 4 for grinding the root of the injection hole burr 2 after cutting. The cutting mechanism 3 And grinding mechanism 4 is driven by driving mechanism 5.

[0021] Preferably, the inner wall of one side of the housing 1 is fixed with a support column 11, the cutting mechanism 3 includes a lead screw 31, the lead screw 31 is horizontally arranged and its two ends are respectively connected to the support column 11 and the inner wall of the housing 1 in rotation, and the lead screw 31 The upper screw thread is fi...

Embodiment 2

[0031] A device for removing burrs from injection molding holes of plastic decorative parts of automobiles, comprising a housing 1, which is provided with a hand-held handle, the bottom of the housing 1 is provided with an opening for the insertion of injection molding hole burrs 2, and the housing 1 is provided with a For the cutting mechanism 3 for cutting the burr 2 of the injection molding hole, the housing 1 is provided with a grinding mechanism 4 for grinding the root of the burr 2 of the injection molding hole after cutting. The cutting mechanism 3 and the grinding mechanism 4 are driven by the driving mechanism 5 .

Abstract

The invention provides an injection-molded hole burr removal device for an automobile plastic decorative part, which includes a housing, wherein an opening for an injection-molded hole burr to extendinto is disposed at the bottom of the housing; a cutting mechanism for cutting the injection-molded hole burr is disposed in the housing; a polishing mechanism that polishs the root of the cut injection-molded hole burr is disposed in the housing; the cutting mechanism and the polishing mechanism are driven by a drive mechanism; the cutting mechanism and the polishing mechanism are linked by a transmission mechanism; a waste discharge port is disposed on a side wall of the housing; and the waste discharge port is connected to a debris-collecting chamber of a dust collecting mechanism. The cutting mechanism of the present invention is integrated in the housing and avoids the situation of damaging other parts of a product when cutting the injection-molded hole burr. The polishing mechanism of the present invention can remove the burr root and polish the burr, which improves the product quality.

Description

technical field [0001] The invention relates to the technical field of manufacturing equipment of automobile parts, in particular to a device for removing burrs from injection holes of plastic decorative parts of automobiles. Background technique [0002] The plastic decorative parts of automobiles will inevitably produce redundant burrs during the injection molding process, and these burrs need to be removed manually after the injection molding is completed. Among these burrs, some burrs located on the edge of the protruding part of the product are easier to handle, while the injection holes are generally located in the recessed part of the product, which leads to the following two problems in manual processing: on the one hand, the space of the recessed part is narrow, which makes it difficult to remove the knife And it is easy to hurt other parts of the product, which increases the reject rate; on the other hand, it is difficult to completely remove the injection hole bur...
