Abstract
The invention discloses a mold core with a knife head, which includes the mold core, an empty cavity arranged at the middle part of the mold core and communicated with the outside of the mold core; the knife head arranged at the head part of the mold core as well as a cut arranged at the end surface of the knife head; the head part of the mold core is provided with a groove; the lower part of the knife head matched with the groove is arranged in the groove; a through hole penetrated with the empty cavity is arranged in the groove; a bolt penetrates the through hole and is tightly and fixedly connected with a screw hole at the bottom part of the knife head; the bottom part of the knife head is also provided with a pin hole; the groove corresponding to the pin hole is also provided with the pin hole; the two ends of a location pin are respectively arranged in the pin hole; the mold core of the invention has the advantages of being capable of prolonging the service life of the whole mold core by the exchange of the knife head; thereby reducing the manufacture cost of a product; the adjusting and the exchanging of the knife head part of the mold core are convenient and the precision of the product can be improved.
Description
Technical field
The present invention relates to the core in a kind of mould, relate in particular to a kind of mold cores that is used to process Medical combined cover.
Background technology
In the production process of Medical combined cover, the enclosing cover that has the serpentine draw ring aspect processing, require with outer hd top face that the serpentine draw ring links to each other on have the indentation of certain depth, make draw ring hd top face outside indentation is torn easily.When producing Medical combined cover, traditional mold cores, its core main body and cutter head all are one, and directly are provided with the edge of a knife on the cutter head, the cutter head part is non-removable with the core main part.The mold cores of this structure in actual use, because regular wearing and tearing can take place in the cutter head of core head, so after using a period of time, because the edge of a knife is is constantly worn and torn, thereby will influence the indentation precision of the outer hd top face of Medical combined cover, influence the quality of product.In order to ensure the quality of production of product, the user usually can only this core of integral replacing, so just can shorten the service life of core greatly, has improved production cost of products.
Summary of the invention
The object of the present invention is to provide a kind of cutter head part to change, with the core of the belt blade head that improves whole core service life.
Further purpose of the present invention is to provide the core of the belt blade head that a kind of cutter head can arbitrarily adjust at the core head.
Further purpose of the present invention be to provide a kind of core inside have cooling device the core of belt blade head.
For realizing purpose of the present invention, a kind of core of belt blade head, comprise core, be arranged on core middle part and with the cavity of core exterior, be arranged on the cutter head of core head, and be arranged on the edge of a knife on the cutter head end face, the head of described core has a groove, the cutter head bottom of matching with groove is arranged in the groove, offer a through hole that connects with cavity in the groove, screw passes screw fastening connect of through hole bottom cutter head, also offers a pin-and-hole in the bottom of cutter head, offer a pin-and-hole with the pin-and-hole corresponding grooves, the two ends of alignment pin are separately positioned in the pin-and-hole;
For realizing further purpose of the present invention, a kind of core of belt blade head also comprises: the pad that is provided with some adjustment usefulness between the bottom of described cutter head and core groove.
For realizing further purpose of the present invention, a kind of core of belt blade head also comprises, is provided with sealing ring between described cutter head and groove, is equipped with a cooling tube in the cavity of described core.
Advantage of the present invention is: can prolong the service life of whole core by the replacing of cutter head, thereby reduce production cost of products; It is convenient that the adjustment of core cutter head part is changed, and can improve the precision of product.
