[0001] The present application relates to the technical field of water-cutting mechanical equipment, and in particular to an automated water-cutting equipment with a screening function. Background Art
[0002] After the plastic workpiece is injection molded, there is usually a sprue formed during the injection molding. Since the remaining sprue will affect the practicality and aesthetics of the workpiece, it is usually cut off by a special sprue cutting machine to facilitate the next step of processing the workpiece. When small plastic parts are injection molded, multiple cavities for molding plastic parts are usually set in the injection mold, so that multiple plastic parts can be produced in one injection molding step. Multiple plastic parts will be connected through a waste frame. Figure 1 , an injection molded workpiece includes a waste frame 19 and a plastic part 20 arranged on the waste frame 19.
[0003] The watertight cutting device is a device used to cut plastic parts from a waste frame. After searching, the Chinese patent authorization announcement number CN218660297U discloses a fully automatic watertight cutting device, including a feeding mechanism, a positioning mechanism, a watertight cutting module, a feeding mechanism and a product handling mechanism. The feeding mechanism is configured to stack a plurality of injection molded workpieces, and the product handling mechanism is used to transport the injection molded workpieces from the feeding mechanism to the positioning mechanism.
[0004] The fully automatic water-cutting device in the above patent has the following shortcomings: although the device eliminates the safety hazards of manual operation, the parts cut off by the above water-cutting device will be mixed together. When there is a problem in a cavity in the injection mold, the plastic part corresponding to the cavity is unqualified, and the unqualified plastic parts will be mixed with the qualified plastic parts, making it difficult to separate the qualified plastic parts from the unqualified plastic parts.

When the cutting is completed, the plastic parts will fall from the corresponding collecting through hole 2 on the positioning groove 9 into the corresponding conveying pipe 6, and fall into the corresponding collecting box 7 through the corresponding conveying pipe 6. Therefore, when defective products are found in the collecting box 7, the specific location of the defective plastic parts can be quickly found, and there is no need for manual screening, which can save time and cost.

A turntable 12 is fixedly installed at one end of the external screw 10. By rotating the turntable 12, the turntable 12 rotates, thereby driving the external screw 10 to rotate and driving the two clamping plates 11 to move away from each other. The two clamping plates 11 move away from each other, thereby limiting and fixing the multiple collection boxes 7 on both sides, thereby preventing the collection boxes 7 from tipping over.

When the cutting is completed, the plastic parts will fall from the corresponding collecting through holes 2 on the positioning groove 9 into the corresponding conveying pipe 6, and fall into the corresponding collecting box 7 through the corresponding conveying pipe 6, so that when defective products are found in the collecting box 7, the specific location of the defective plastic parts can be quickly found, and there is no need for manual screening, which can save time and cost;
[0043] By rotating the turntable 12, the turntable 12 will drive the external screw 10 to rotate and drive the two clamping plates 11 to move away from each other.
