Description

Technical Field

[0001] This utility model relates to the field of electrocardiogram recorder technology, and in particular to a burr removal device for injection molding production. Background Technology

[0002] When producing cylindrical bodies using injection molding, molten plastic is typically injected into a mold and then cooled to obtain the formed cylindrical body. Due to the influence of the injection molding equipment, burrs are generated at the edges and other areas. The presence of burrs reduces the quality grade of the product and makes assembly inconvenient. Therefore, burr removal is necessary after injection molding.

[0003] Chinese Patent No. CN219542639U discloses a burr removal device for injection molding barrel production, comprising a frame, a grinding machine, and a dust collection device. The grinding machine is vertically mounted on the frame. The dust collection device includes a collection hopper, an air pipe, and an air pump. The collection hopper is located below the grinding machine and moves with it. The two ends of the air pipe are connected to the collection hopper and the air pump, respectively. The air pump is mounted on the frame. The frame is equipped with a drive mechanism for moving the grinding machine, which facilitates the recovery of burrs generated during the grinding of the barrel.

[0004] The shortcomings of the existing technical solutions are as follows: During the grinding and positioning process of the injection molding barrel, the grinding mechanism is driven to move up and down by a threaded rod and to move laterally by a cylinder. Due to the instability of the air source of the cylinder, it is difficult for the grinding mechanism to achieve precise lateral movement. For a frustum-shaped injection molding barrel, its side mold parting line is an oblique line. During the up and down movement of the grinding mechanism, precise lateral movement is required to achieve oblique movement. The existing device has poor grinding effect on the side mold parting line of the frustum-shaped injection molding barrel and has poor applicability. Utility Model Content
