Abstract
The utility model discloses a mold core with a tool bit, which includes a mold core, a hollow cavity arranged at the middle part of the mold core and communicated with the outside of the mold core, the tool bit arranged at the head part of the mold core, and a blade arranged on the end surface of the tool bit. A flute is formed at the head part of the mold core; the lower part of the tool bit is matched with the flute and arranged in the flute; a through hole communicated with the hollow cavity is formed in the flute; a bolt passes through the through hole and is fastened and connected with a screw at the bottom part of the tool bit; a pin hole is formed at the bottom part of the tool bit, and a corresponding pin hole is formed in the flute; and the two ends of a positioning pin are arranged in the pin holes respectively. The utility model has the advantages that the service life of the whole mold core can be prolonged and the production cost of products can be reduced through the replacement of tool bits; and the adjustment of the tool bit part of the mold core is convenient, thereby improving the precision of products.
Description
Technical field
The utility model relates to the core in a kind of mould, relates 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.
The utility model content
The purpose of this utility model 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 utility model 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 utility model be to provide a kind of core inside have cooling device the core of belt blade head.
For realizing the purpose of this utility model, 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 utility model, 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 utility model, 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.
The utility model has the advantages that: 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.
