Description

Technical Field

[0001] This utility model relates to the field of scrap cutting technology, specifically to a scrap cutting device for automotive injection molded parts. Background Technology

[0002] Injection molding scrap cutting refers to the operation of cutting or trimming the edges or unwanted parts of the produced product during the plastic injection molding process. This process usually occurs after the plastic product is taken out of the mold. In order to meet the product design specifications or improve the appearance quality of the product, it is necessary to trim the edges or excess material of the product.

[0003] When cutting scrap materials, a wire saw is used. Because the cutting width of a wire saw is smaller, it can cut more accurately. The wire saw mainly achieves cutting through the reciprocating motion of the wire. However, automotive injection molded parts often have holes, grooves, or some ring-shaped workpieces. For side cutting of the inner scrap materials of such workpieces, the saw teeth need to pass through the center hole. Achieving this purpose on a closed ring structure is relatively difficult, which reduces the overall practicality. Utility Model Content

[0004] The purpose of this invention is to provide a cutting device for scrap materials from automotive injection molded parts, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wire saw frame, the front end of which is an open structure, and a saw tooth line is vertically installed at the opening. A wire groove is provided inside the wire saw frame, and a traction line is installed in the wire groove. The traction line passes through the wire groove and its two ends are connected to the two ends of the saw tooth line. A drive component is provided at the bottom connection point of the traction line and the saw tooth line, and a wiring component is provided at the upper connection point of the traction line and the saw tooth line.

[0006] Preferably, the drive assembly includes a telescopic cylinder and a drive groove. The drive groove is located at the bottom connection of the traction line and the sawtooth line. A telescopic block is slidably connected in the drive groove. The ends of the traction line and the sawtooth line are respectively fixed to both sides of the telescopic block. A drive block is fixed to the upper end of the telescopic block. A telescopic cylinder is fixed to the bottom of the wire saw frame, and the output end of the telescopic cylinder is fixed to the drive block.

[0007] Preferably, the wiring assembly includes a fixed sleeve and a wiring block. The fixed sleeve is fixed above the front opening of the wire saw frame. A movable groove is provided inside the fixed sleeve. A movable block is slidably connected inside the movable groove. An extension block is fixed to the bottom of the movable block. The bottom of the extension block extends out of the fixed sleeve. The end of the traction line extends out of the groove and is fixed to the movable block. A threaded sleeve is fixed to the bottom of the extension block, and a threaded sleeve is threadedly connected to the threaded head. The wiring block is installed inside the threaded sleeve. A fixed block is fixed to the bottom of the wiring block. The bottom of the fixed block extends out of the threaded sleeve and is fixed to the upper end of the saw tooth line.

[0008] Preferably, the threaded sleeve has a through hole at the bottom and a positioning groove on the inner side of the threaded sleeve. The positioning groove and the through hole have the same length and are arranged in a cross shape.

[0009] Preferably, the size of the wiring block is adapted to the size of the through hole, and the thickness of the wiring block is the same as the depth of the positioning groove.

[0010] Preferably, each corner of the groove is rotatably connected to a guide wheel.

[0011] Compared with the prior art, the advantages of this utility model are: using a wire saw to cut scrap materials, and setting a quick-release structure at the connection between the end of the saw teeth and the traction line, it is more convenient to cut the inner diameter scrap materials of ring-shaped workpieces, thus increasing the overall practicality.

The bottom of the wire saw frame 1 is fixed with the telescopic cylinder 23, and the output end of the telescopic cylinder 23 is fixed to the drive block 22.

[0019] The wiring assembly 3 includes a fixed sleeve 4 and a wiring block 5. The fixed sleeve 4 is fixed above the front opening of the wire saw frame 1. The fixed sleeve 4 has a movable groove 41 inside, and a movable block 42 is slidably connected inside the movable groove 41. An extension block 43 is fixed to the bottom of the movable block 42, and the bottom of the extension block 43 extends out of the fixed sleeve 4. The end of the traction wire 14 extends out of the wire groove 11 and is fixed to the movable block 42.

[0020] Working principle: First, connect the entire device to an external power source. Then, using the extension and retraction of the telescopic cylinder 23, the drive block 22 and the telescopic block 21 are driven to extend and retract, achieving reciprocating pulling of the serrated line 12. At this time, the scrap plastic parts are brought close to the serrated line 12, thus achieving the purpose of scrap removal. When cutting the scrap on the inner side of the ring structure, the upper end of the serrated line 12 can be removed from the threaded sleeve 45. Then, the upper end of the serrated line 12 is passed through the middle of the ring structure and fixed, thus removing the scrap on the inner side. During the entire process, the threaded sleeve 45 can be removed by rotating it. The wiring slot 11 can be taken out from the positioning slot 47 and rotated to align with the through hole 46 for quick removal. Conversely, the wiring block 5 is inserted from the through hole 46 and snapped into the positioning slot 47. Finally, the threaded sleeve 45 is threaded to fix the wiring block 5.
