Abstract
The utility model discloses a 45-degree parting 'O'-shaped ring manufacturing die, which comprises an upper die and a lower die. The upper die is provided with an upper cavity for an 'O'-shaped ring, and the lower die is provided with a lower cavity matching with the upper cavity. The manufacturing die further comprises an upper die plate and a lower die plate, the upper die is mounted on the upper die plate in an embedded manner, the lower die is mounted on the lower die plate in an embedded manner, the upper die is provided with a conical convex surface, the upper cavity for the 'O'-shaped ring is arranged on an inclined surface of the conical convex surface, the lower die is provided with a conical concave surface matching with the conical convex surface, and the lower cavity corresponding to the upper cavity for the 'O'-shaped ring is arranged on an inclined surface of the conical concave surface. The 'O'-shaped ring produced by the 'O'-shaped ring manufacturing die forms a 45-degree parting surface, not only has better sealing property compared with a traditional 'O'-shaped ring with a 180-degree parting surface, but also overcomes shortages of flash, dislocation and the like. Simultaneously, as the 45-degree parting 'O'-shaped ring manufacturing die is manufactured into a multi-cavity die generally, production efficiency can be increased.
Description
Technical field
The utility model relates to a kind of " O ", and the type circle prepares mould.
Background technology
Traditional " O " type circle prepares mould, all adopt 180 degree die joint combinations, it is the bottom that upper impression is opened in patrix, lower impressions is opened in the top of counterdie, combination by upper and lower mould makes " O " type circle, adopts traditional mould preparation " O " type circle, locatees not firm, be easy to generate dislocation, defect rate height during preparation " O " type circle; The gap of the profile of mould is bigger, and sealing is not good, is easy to generate overlap, makes " O " type circle of producing also need increase the operation of removing overlap, its inefficiency.And " O " type circle of 180 degree die joints in use, and sealing property is bad.
The utility model content
The purpose of this utility model is in order to overcome technological deficiency recited above, to provide a kind of " O " type circle to prepare mould.
In order to solve technical problem recited above, the utility model is taked following technical scheme:
The utility model provides a kind of " O ", and the type circle prepares mould, include patrix, counterdie, patrix offers the upper impression of " O " type circle, counterdie offers the lower impressions that cooperates with upper impression, the preparation mould also includes cope match-plate pattern and lower bolster, patrix embeds and is installed on cope match-plate pattern, counterdie embeds and is installed on lower bolster, patrix offers the taper convex surface, on the inclined plane of taper convex surface, offer the upper impression of " O " type circle, counterdie offers the tapered concave surface that matches with the taper convex surface, offers the corresponding lower impressions of upper impression with " O " type circle on the inclined plane of tapered concave surface.
As a kind of preferred version, the angle of inclination on the inclined plane of taper convex surface is 45 degree, and the angle of inclination on the inclined plane of taper concave surface is 45 degree.
The inclined plane of taper convex surface is bright and clean inclined-plane; The inclined plane of taper concave surface is bright and clean inclined-plane.
Cope match-plate pattern is equipped with at least two patrixes, and lower bolster is provided with patrix quantity and equates and corresponding counterdie.
The utility model is made generally in combination die, locatees by the taper convex surface of patrix and the taper concave surface stationary fit of counterdie, and upper and lower mould is inlayed assembly respectively on upper and lower template, so that produce in batches, enhances productivity.
The mode that the utility model adopts taper convex surface and the stationary fit of taper concave surface to locate, it is firm and cause the problem that misplaces to have solved traditional location; Upper and lower die cavity is opened in respectively on 45 inclined planes of spending of taper convex surface, taper concave surface, forms 45 degree die joints,, occur the problem of overlap when having solved preparation " O " type circle by combining closely of two inclined planes.Make combination die, upper and lower mould is inlayed assembly respectively on upper and lower template,, enhance productivity so that produce in batches.45 the degree die joints " O " type circle in use, good seal performance.

Fig. 1 prepares the explosion views of mould embodiment one for " O " type circle.
Fig. 2 is the explosion views of the patrix of Fig. 1.
Fig. 3 is the explosion views of the counterdie of Fig. 1.
Fig. 4 prepares the explosion views of mould embodiment two for " O " type circle.
Among the figure, 1. cope match-plate pattern, 2. patrix, 3. counterdie, 4. lower bolster, 5. die cavity, 51. upper impression, 52. lower impressions, 6. taper convex surface, 7. taper concave surface.
The specific embodiment
See also Fig. 1 to Fig. 3, as shown in the figure, " O " type circle prepares mould and includes patrix 2, counterdie 3, cope match-plate pattern 1 and lower bolster 4; Patrix 2 offers the upper impression 51 of " O " type circle, and counterdie 3 offers the lower impressions 52 that cooperates with upper impression 51, and patrix 2 embeds and is installed on cope match-plate pattern 1, and counterdie 3 embeds and is installed on lower bolster 4; Patrix 2 offers taper convex surface 6, on the inclined plane of taper convex surface 6, offer the upper impression 51 of " O " type circle, counterdie 3 offers the tapered concave surface 7 that matches with taper convex surface 6, offers the upper impression 51 corresponding lower impressions 52 with " O " type circle on the inclined plane of tapered concave surface 7; The angle of inclination on the inclined plane of taper convex surface 6 is 45 degree, and the angle of inclination on the inclined plane of taper concave surface 7 is 45 degree; The inclined plane of taper convex surface is bright and clean inclined-plane, and the inclined plane of taper concave surface is bright and clean inclined-plane;
See also Fig. 4, as shown in the figure, cope match-plate pattern is equipped with at least two patrixes, and lower bolster is provided with patrix quantity and equates and corresponding counterdie.Generally in preparation process, edge is pieced together how secondary upper and lower mould on the template of a mold, and the upper and lower mould of every pair all has " O " type circle die cavity, thereby makes a mold form combination die, enhances productivity.
