Abstract

The utility model belongs to the technical field of mold design and manufacturing, and in particular relates to a positioning structure of a mold. The positioning structure of the mold comprises an upper mold and a lower mold which is matched with the upper mold, and is characterized in that a triangular positioning bump is arranged at each of a pair of diagonal corners of the mold surface of the lower mold; a triangular positioning groove is formed in each of the other pair of diagonal corners of the mold surface of the lower mold; triangular positioning grooves which respectively correspond to the triangular positioning bumps on the mold surface of the lower mold are formed in a pair of diagonal corners of the mold surface of the upper mold; and triangular positioning bumps which correspond to the triangular positioning grooves in the mold surface of the lower mold are arranged in the other pair of diagonal corners of the mold surface of the upper mold. The positioning structure of the mold has the beneficial effects that in a mode of arranging the positioning structures at the diagonal corners of the upper mold and the lower mold, the upper mold and the lower mold are not in contact before the mold is assembled; the mold is not easy to abrade, bias and displace, is easy to process and is low in cost; and the positioning structure can be widely applied to the die assembly process in the mold machining process.

Description

The location structure of mould

Technical field

The utility model belongs to mould design and manufacturing technology field, relates to a kind of location structure of mould specifically.

Background technology

Mould is manufacturing fundamental technology equipment, because the technical merit of mould is determining the quality of product to a great extent, thereby the height of the production technology level of mould, oneself becomes the important symbol of weighing an enterprise product level height, and guiding in the mould and detent mechanism are one of critical pieces of mould, and it guarantees workpiece accuracy to prolonging die life, simplify mould structure, reduce die cost and have higher value.

The guiding of existing mold and detent mechanism generally are to process lead on counterdie, on patrix, process gathering sill, realize mould location up and down by lead and gathering sill, there is following defective: l in this kind locate mode, processing lead and gathering sill complex process on mould, and the own required precision of lead and gathering sill is higher, in case skew occurs, will cause the mold cavity dislocation, cause mould to be scrapped; 2, adopt the mode of reference column, when spacing was big before mould matched moulds up and down, reference column promptly was touched, and reference column is easy to be worn, thereby makes mould produce eccentric, dislocation.

Summary of the invention

The utility model provides a kind of location structure of mould in order to overcome the deficiencies in the prior art, occurs dislocation, the inaccurate problem in location when having solved matched moulds easily.

In order to achieve the above object, the utility model has designed a kind of location structure of mould, comprise patrix, with patrix to the coupling counterdie, it is characterized in that: a pair of diagonally opposing corner of described counterdie die face is respectively established a triangle positioning convex piece, its another diagonally opposing corner is respectively established a triangle detent, the a pair of diagonally opposing corner of described patrix die face is provided with the corresponding triangle detent of triangle positioning convex piece with the counterdie die face, and another of described patrix die face is provided with the corresponding triangle positioning convex of triangle detent piece with the counterdie die face to diagonally opposing corner; At the matched moulds state of patrix and counterdie, the triangle positioning convex piece of described patrix embeds respectively in the triangle detent of counterdie, and the triangle positioning convex piece of described counterdie embeds respectively in the triangle detent of patrix.

The beneficial effects of the utility model are: adopt the mode that location structure is set at upper and lower mould diagonally opposing corner, this kind mode upper and lower mould before the mould matched moulds does not contact, not easy to wear, be difficult for eccentric, dislocation, and Mould Machining is simple, with low cost, can be widely used in the matched moulds process in the Mould Machining process.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

The schematic diagram of matched moulds state in Fig. 2 the utility model.

Referring to Fig. 1 and Fig. 2,1 is counterdie; 2 is patrix; 3 is triangle positioning convex piece; 4 is the triangle detent.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described further.

Referring to Fig. 1 and Fig. 2, the utility model comprise patrix 2, with patrix 2 to the coupling counterdie 1, the a pair of diagonally opposing corner of counterdie 1 die face is respectively established a triangle positioning convex piece 3, its another diagonally opposing corner is respectively established a triangle detent 4, the a pair of diagonally opposing corner of patrix 2 die faces is provided with the triangle positioning convex piece 3 corresponding triangle detents 4 with counterdie 1 die face, and another of patrix 2 die faces is provided with triangle detent 4 corresponding triangle positioning convex pieces 3 with counterdie 1 die face to diagonally opposing corner; At the matched moulds state of patrix 2 with counterdie 1, the triangle positioning convex piece 3 of patrix 2 embeds respectively in the triangle detent 4 of counterdie 1, and the triangle positioning convex piece 3 of counterdie 1 embeds respectively in the triangle detent 4 of patrix 2.

The utility model is provided with the mode of location structure at four diagonally opposing corners of upper and lower mould, this kind mode upper and lower mould before the mould matched moulds does not contact, not easy to wear, be difficult for eccentric, dislocation, and Mould Machining is simple, with low cost, can be widely used in the matched moulds process in the Mould Machining process.

Claims
