Technical Field

[0001] The utility model relates to the technical field of injection molding product processing equipment, in particular to a waste edge cutting device for injection molding product processing. Background Art

[0002] Injection molding is a method for producing industrial products. Products are usually produced using rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding and die casting. After the plastic products produced by injection molding are removed from the plate, the surface will have residual waste edges of the plate flow channel, commonly known as sprues. The existence of sprues not only affects the appearance but also scratches the hands during touch or use. Therefore, sprues often need to be removed. The current method of removing sprues is for the user to hold the plastic part and use pliers to cut the sprue on it. This is time-consuming and labor-intensive. When the cutting edges of the pliers are not parallel, the cut sprues are sharp and can easily scratch the user. At the same time, when the plastic part is a plastic sheet, it is more difficult to grab and cut.

[0003] To solve the above problems, the existing technology patent (CN212498794U) discloses a nozzle cutting device for injection molded plastic products, which is used to cut the nozzle on the plastic plate. It includes a base plate, and clamps are symmetrically arranged on both sides of the base plate surface, and the distance between the clamps and the base plate is equal to the thickness of the plastic plate; the base plate surface is slidably connected to a cutting slider, and the cutting slider is located between the clamps on both sides, and a cutting blade is fixedly connected to the cutting slider, and the distance between the cutting blade and the base plate surface is equal to the thickness of the plastic plate. The utility model provides a clamping plate so that it can clamp and fix the specific plastic plate for cutting the nozzle, thereby solving the problem that the plate is difficult to clamp and grasp. By providing a slidable cutting slider and cutting blade, the user can quickly cut the nozzle by pushing the cutting blade, so that the device can quickly and smoothly cut the nozzle on the plastic plate.

The top plate 103 is fixedly connected to the two support plates 102 and is located above the support plates 102. The cutting assembly includes a fixing rod 104, a placement plate 105, a collection frame 106, a cylinder 107, a push plate 108, a holding block 109, two telescopic rods 110, two springs 111, a fitting frame 112, an adjusting member and a cutting member. The fixing rod 104 is fixedly connected to the workbench 101 and is located on the outside of the support plates 102. The placement plate 105 is fixedly connected to the The fixing rod 104 is fixedly connected and located above the fixing rod 104. The collecting frame 106 is detachably connected to the workbench 101 and is located on the outside of the fixing rod 104. The cylinder 107 is fixedly connected to the top plate 103 and is located above the top plate 103. The pushing plate 108 is fixedly connected to the output end of the cylinder 107 and is located below the top plate 103. The holding block 109 is fixedly connected to the pushing plate 108 and is located below the pushing plate 108. The two telescopic rods 110 are fixedly connected to the pushing plate 108 and are located on the outside of the holding block 109.

When in use, the collecting frame 106 is placed on the outside of the fixing rod 104, and the injection molded product is placed on the top of the placing plate 105. The cylinder 107 pushes the pushing plate 108 downward, and the fitting frame 112 fits the injection molded product. The telescopic rod 110 and the spring 111 are compressed so that the fitting frame 112 presses the injection molded product tightly, thereby preventing the injection molded product from moving during the fixing process. After the abutting block 109 completely fixes the injection molded product, it stops pressing downward, thereby achieving the purpose of fixing injection molded products of different sizes. The product is fixed, the driving motor 113 drives the rotating rod 114 to rotate, the moving block 115 drives the bottom plate 116 to move, the moving plate 117 drives the sliding frame 118 to move, and the sliding frame 118 slides in the top plate 103, so that the moving plate 117 can move stably, and the electric cylinder 119 pushes the mounting plate 120 to move outward, and the waste edge of the injection molded product is cut off by the double-edged cutter 121, and the cut waste edge falls into the collection frame 106, so as to facilitate the fixation of injection molded products of different sizes, and the position of the cutter can be adjusted according to the different positions of the waste of the injection molded products, thereby improving the practicality and convenience of the equipment.
