Description

core with blade

technical field

The invention relates to a mold core in a mold, in particular to a mold core for processing a medical composite cover.

Background technique

In the production process of the medical composite cover, in terms of processing the outer cover with the "S" shaped pull ring, it is required to have a certain depth of notch on the top surface of the outer cover connected with the "S" shaped pull ring, so that the pull ring can Easily tear off the top surface of the outer cover along the notch. When producing medical combination caps, the core body and the cutter head of the traditional mold core are integrated, and the cutter head is directly provided with a knife edge, and the cutter head part and the core body part are not detachable. During the actual use of the mold core of this structure, the cutter head of the core head will be frequently worn, so after a period of use, the outer cover of the medical combination cover will be affected due to the continuous wear of the knife edge. The scoring accuracy of the surface affects the quality of the product. In order to ensure the production quality of the product, the user usually can only replace the core as a whole, which will greatly shorten the service life of the core and increase the production cost of the product.

Contents of the invention

The purpose of the present invention is to provide a core with a cutter head which can be replaced to improve the service life of the whole core.

A further object of the present invention is to provide a core with a cutter head which can be freely adjusted at the head of the core.

A further object of the present invention is to provide a core with a cutter head and a cooling device inside the core.

In order to achieve the purpose of the present invention, a core with a cutter head includes a core, a cavity that is arranged in the middle of the core and communicates with the outside of the core, a cutter head that is arranged at the core head, and a cutter head that is arranged on the cutter head. The knife edge on the end face, the head of the core has a groove, and the lower part of the cutter head matched with the groove is arranged in the groove, and a through hole connected with the cavity is opened in the groove, and the screw passes through the through hole. The hole is fastened to the screw hole at the bottom of the cutter head, and a pin hole is provided at the bottom of the cutter head, and a pin hole is provided in the groove corresponding to the pin hole, and the two ends of the positioning pin are respectively arranged in the pin hole;

In order to achieve a further object of the present invention, a core with a cutter head further includes: a number of spacers for adjustment are arranged between the bottom of the cutter head and the groove of the core.

In order to achieve the further purpose of the present invention, a core with a cutter head also includes a sealing ring arranged between the cutter head and the groove, and a cooling ring is pierced in the cavity of the core Tube.

The invention has the advantages that: the service life of the entire core can be extended through the replacement of the cutter head, thereby reducing the production cost of the product; the adjustment and replacement of the cutter head part of the core is convenient, and the precision of the product can be improved.
