Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, and in particular to a cutting device for post-injection molding residue. Background Technology

[0002] Injection molding is a method of industrial product manufacturing. Products are typically produced using rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding compression molding and die casting. An injection molding machine is the main molding equipment used to create various shapes of plastic products from thermoplastic or thermosetting materials using plastic molds. Injection molding is achieved through an injection molding machine and molds. Various plastic products formed by injection molding machines often have sprue residue, which needs to be cut and processed.

[0003] Currently, the existing cutting method involves manually trimming the sprue with sprue shears and knives. Due to the large scale of production, this requires a lot of manpower and the trimming efficiency is low. Utility Model Content

The truss 31 is connected to the top of the base 1, the slide 32 is slidably connected to the truss 31 and located on one side of the truss 31, the X-axis feed mechanism 33 is mounted on the truss 31 and connected to the slide 32, the Y-axis feed mechanism 34 is mounted on the top of the slide 32, the Z-axis feed mechanism 35 is mounted on one side of the Y-axis feed mechanism 34, and the laser cutting head 36 is mounted on the side of the Z-axis feed mechanism 35 away from the Y-axis feed mechanism 34.

[0019] In this embodiment, the base 1 provides support and installation space for the other mechanisms. The positioning clamp 2 is used to clamp and fix the injection molded part on the base 1 to achieve positioning of the injection molded part. The cutting component 3 is controlled by a preset program to automatically perform laser cutting on the sprue of the injection molded part below. The cutting residue falls into the recycling component 4 for recycling. Specifically, the worker uses his hand to place the injection molded part on the base 1, and performs initial positioning by the positioning pin on the base 1. When the sensor (existing technology, not shown in the figure) installed on the positioning clamp 2 senses the injection molded part, the controller program controls the positioning clamp 2 to move and clamp and fix the injection molded part. At this time, the X-axis feed mechanism 33 drives the carriage 32 on the truss The laser cutting head 36 slides on the frame 31, thereby driving it to move in the X-axis direction. At the same time, the Y-axis feed mechanism 34 is activated, driving the laser cutting head 36 to move in the Y-axis direction, thus adjusting the processing angle of the laser cutting head 36. Finally, the Z-axis feed mechanism 35 is activated, driving the laser cutting head 36 to move in the Z-axis direction, thus lowering the laser cutting head 36 to cut the sprue of the injection molded part, completing the cutting process of the injection molded part. Compared with manual trimming, laser cutting by the cutting assembly 3 is faster and produces a smoother cut, greatly improving the cutting efficiency and quality of the sprue of the injection molded part. At the same time, it also reduces the workload of workers, thus solving the problem of low trimming efficiency in traditional manual trimming of injection molded part sprues.

[0023] In this embodiment, the telescopic rod 21 is a commercially available electric telescopic rod. The controller drives the output end of the telescopic rod 21 to extend, thereby driving the clamping block 22 to approach the injection molded part until the rubber pad 23 abuts against the injection molded part and stops, thus achieving the positioning and fixing of the injection molded part. The rubber pad 23 is provided to protect the injection molded part and prevent the clamping block 22 from making hard contact with the injection molded part and damaging it.
