Description

Technical Field

[0001] The utility model relates to the field of nozzle punching equipment, in particular to an automatic nozzle punching device in a mold. Background Art

[0002] During the injection molding process, the plastic melt enters the mold cavity through the gate system. The in-mold gate primarily connects the molded part to the runner system. It typically includes a sprue bushing, main runner, branch runners, and gate. A punching device is required to process the gate of the injection-molded part. Current automatic in-mold gate punching devices struggle to provide stable guidance for the punching tool, necessitating a new device.

[0003] The existing in-mold sprue automatic punching device is not convenient for stably guiding the punching tool during use, causing the punching tool to deviate from the predetermined punching path due to the reaction force generated during punching, vibration of the equipment, etc. This deviation not only leads to inaccurate punching position and inability to accurately separate the sprue from the injection molded part, but may also cause unnecessary damage to the injection molded part itself, affecting the quality and appearance of the product, and it is inconvenient to disassemble and replace the worn punching tool. Therefore, there is an urgent need for an in-mold sprue automatic punching device. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide an automatic punching device for an in-mold sprue to solve the problem that the existing automatic punching device for an in-mold sprue is inconvenient to stably guide the punching tool and to disassemble and replace the worn punching tool.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automatic in-mold water nozzle punching device, comprising a base, the top of the base is fixedly connected to a guide rod, the top of the guide rod is fixedly connected to a frame plate, the top of the frame plate is fixedly connected to a hydraulic rod, the output end of the hydraulic rod is fixedly connected to a receiving plate, and the outer wall of the receiving plate is fixedly connected to the guide plate.

[0006] A threaded hole is provided inside the receiving plate, a bolt is installed inside the receiving plate, an insert block is installed inside the receiving plate, a limiting hole is provided inside the insert block, a punching tool is fixedly connected to the bottom of the insert block, and a placement table is installed on the top of the base.

[0007] A card slot is provided inside the base, a collection box is movably connected inside the base, and a protrusion is fixedly connected to the outer wall of the collection box.

[0008] Preferably, the guide plate is of open-hole design, and the guide plate and the guide rod form a sliding structure.

[0009] Preferably, the guide rods are symmetrically arranged with respect to the central axis of the base, and the frame plate is arranged parallel to the base.

[0010] Preferably, the receiving plate is of slotted design, and the receiving plate is snap-connected with the inserting block.

[0011] Preferably, the receiving plate is threadedly connected to the bolt through a threaded hole, and the bolt is snap-connected to the insert block through a limiting hole.

[0013] Preferably, the protrusion is engaged with the base through a slot, and the protrusion is symmetrically arranged with respect to the central axis of the collection box.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The utility model is provided with a guide rod, a hydraulic rod, a receiving plate, a guide plate, a punching tool and a placement table. By placing a workpiece with a nozzle on the placement table and activating the hydraulic rod, the receiving plate can be moved, so that the guide plate slides down steadily along the guide rod, driving the punching tool to move down and punch the workpiece placed on the placement table, thereby facilitating the stable guidance of the punching tool, preventing it from deflecting during the punching process, and improving the quality of the punching process;

[0016] 2. The utility model is provided with a receiving plate, a bolt, an insert, a limiting hole and a punching tool. By rotating the bolt, the bolt can be rotated and removed from the limiting hole. Pulling the punching tool downward can remove the insert from the receiving plate, so that the punching tool can be disassembled, which facilitates the disassembly and replacement of the worn punching tool.

[0017] 3. The utility model is provided with a base, a card slot, a collection box and a protrusion. By moving the collection box, it is slid and inserted along the base, so that the protrusion is squeezed and deformed. When the collection box is fully inserted into the base, the protrusion can be restored and stuck in the card slot for limiting the position, which makes it easy to collect and place the workpiece after the water outlet is removed.
