[0022] Example 1

[0023] like Figure 1-3 As shown, this embodiment introduces an automatic cutting structure for the cold well in the injection molding mold, including: a mold body 1, a metal part 2, a plastic 3, a process glue cold well 4 and a cutting mechanism; the metal part 2 is placed inside the mold body 1, and the two ends of the metal part 2 are coated with the plastic 3. After injection molding, the two sides of the plastic 3 produce the process glue cold well 4, and the cutting mechanism is directly opposite to the root of the process glue cold well 4. The cutting mechanism includes a cutter 5, a floating plate 6, an air / oil cylinder 7, a spring 8, an air / oil circuit 9 and a high-pressure air / oil circuit connector 10. The cutter 5 is arranged directly at the root of the process glue cold well 4. Above, the floating plate 6 is fixed above the cutter 5, one end of the spring 8 is fixed below the floating plate 6, and the other end is fixed on the mold body 1, the air / oil cylinder 7 is fixed above the floating plate 6, the air / oil circuit 9 is located above the air / oil cylinder 7 and one end is connected to the air / oil cylinder 7, and the other end is connected to the outside of the mold body 1 and connected to the high-pressure air / oil circuit connector 10. By setting a cutting mechanism, the process glue cold well 4 generated on both sides of the plastic 3 can be quickly cut, which can free the workers' hands, save costs, and improve efficiency. In addition, this structure can also be used to cut off the gate in the mold to separate the product from the gate.

[0024] like Figure 2 As shown, the spring 8 is provided with multiple groups, and the multiple groups of springs 8 are evenly distributed between the floating plate 6 and the mold body 1. The gap between the floating plate 6 and the mold body 1 is smaller than the thickness of the process glue cold material well 4 by 1 to 2 mm, so that after cutting, the process glue cold material well 4 connected with the plastic 3 can be ejected together, and then the cut process glue cold material well 4 can be pulled off; the gap between the floating plate 6 and the mold body 1 is equal to the thickness of the process glue cold material well 4, and the mold body 1 is provided with an ejector pin at a position below the process glue cold material well 4, so as to facilitate the rapid ejection of the process glue cold material well 4; two groups of cutters 5 are provided below the floating plate 6, and the two groups of cutters 5 are respectively facing the process glue cold material well 4 generated on both sides of the plastic 3, so as to facilitate the simultaneous processing of the process glue cold material well 4 on both sides.

[0025] The automatic cutting structure of the injection molding cold well mold provided in this embodiment has the following working principle:

[0026] When in use, the metal part 2 is placed into the wooden sword body for mold closing injection molding. After injection molding, process glue cold material wells 4 are generated on both sides of the plastic 3. The float plate 6 is driven down by the high-pressure gas / oil circuit 9 and the gas / oil cylinder 7. The process glue cold material wells 4 on both sides of the plastic 3 are cut by the cutter 5 on the float plate 6. After cutting, the float plate 6 is reset to the initial position under the action of the spring 8, and the product / material head is pushed out for the next process.

[0027] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
