Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, a novel mold structure for a full-automatic water cutting opening of an injection molding machine comprises a lower mold 1, a water cutting opening insert 2, a feeding cavity 5 and a product cavity 9, and further comprises:

the first sliding chute 3 is formed in the right side of the inner part of the water cutting opening insert 2, the inner wall of the first sliding chute 3 is connected with a first ejector pin 4 in a sliding mode, and the top end of the first ejector pin 4 extends to the upper portion of the inner cavity of the first sliding chute 3 and is in contact with the bottom of the feeding cavity 5;

the top of the water cutting opening insert 2 extends to the upper part of the surface of the top of the lower die jade 1, the knife edge 6 is arranged above the surface of the lower die jade 1 and is positioned at the upper end part of the surface of the water cutting opening insert 2, two sides of the knife edge 6 are respectively communicated with the feeding cavity 5 and the product cavity 9, the connector of the knife edge 6 communicated with the product cavity 9 is a small opening, and the connector of the knife edge 6 communicated with the feeding cavity 5 is a large opening, so that a product is easy to cut under the action of the second ejector pin 8, and the cut is tidy;

the number of the second sliding grooves 7 is 2, the second sliding grooves are formed in the cutting nozzle insert 2, the inner wall of the second sliding groove 7 is connected with a second ejector pin 8 in a sliding mode, the top end of the second ejector pin 8 extends to the position above the cutting nozzle insert 2, and the surface of the bottom of the product cavity 9 is in contact with the top end of the second ejector pin 8.

Specifically, as shown in fig. 1-3, a groove 10 is formed on the surface of the top of the water cutting opening insert 2, and the groove 10 is arranged so that the mold structure can be fitted with a product.

Specifically, as shown in fig. 1-3, the surface of the inner wall of the knife edge 6 is arc-shaped, and the bottom of the inner cavity of the knife edge 6 is inclined, so that the water gap of the product can slide out of the inner wall of the knife edge 6.

Specifically, as shown in fig. 1 to 3, the outer diameter of the first thimble 4 is larger than the outer diameter of the second thimble 8, and the first thimble 4 and the second thimble 8 are both made of wear-resistant materials with the same material, so that the service life of the first thimble 4 and the second thimble 8 can be prolonged.

The working principle is as follows: when the injection molding machine works, raw materials enter the feeding cavity 5 through the injection port and then enter the product cavity 9 through the knife edge 6, after injection molding is completed, the upper die is moved away, the second ejector pin 8 is pushed upwards to enable the product in the product cavity 9 to move upwards, and the product is automatically separated from the raw materials in the feeding cavity 5 due to the small gap between the water cutting port insert 2 and the knife edge 6. The water gap cutting operation of the product is completed, the cut is very flat in the process, and the water gap cutting operation efficiency is higher.
