Abstract
The utility model discloses a stepped intermediate die which consists of an upper half die and a lower half die, wherein positioning pin holes and screw holes for fixing are formed in the outer edges of the upper half die and the lower half die; and the positioning pin holes and the screw holes for fixing are symmetrically distributed along the outer edge of the upper half die. The intermediate die is divided into the upper half die and the lower half die; the upper half die and the lower half die can be independently processed by adopting a slow wire walking mode, and thus the consistency of the integral precision of the die is ensured. The positioning pin holes and the screw holes for fixing are symmetrically formed in the outer edges of the upper half die and the lower half die, so that the upper half die and the lower half die are accurate in combination and positioning during combination.
Description
Technical field
The utility model relates to mould in a kind of mould, particularly relates to the middle mould of a kind of step cavity surface type suitable for reading complexity.
Background technology
Tradition has the middle mould of step to be generally an integral body, and the upper and lower opening die cavity adopts respectively spark machined and slow wire feeding processing.Spark machined is the special process method of the galvanic action ablation conductive material that produces when utilizing the two interpolar pulsed discharge be immersed in the working solution, its precision is relatively poor, and slow wire feeding is a kind of of Wire EDM, utilize the fine wire (being called wire electrode) of continuous moving to make electrode, workpiece is carried out pulse spark electric discharge removal metal, excision forming, and the deviation from circular from of this processing mode, straight line error and scale error are all less.Mould in traditional integrally formed step is because the profile impact can't adopt single processing mode to finish processing, so cause the inconsistent problem of each several part precision in the whole mould.
The utility model content
The purpose of this utility model provides mould in the consistent step of a kind of mould each several part precision.
The technical solution of the utility model is such: mould in a kind of step, it is characterized in that: described middle mould is comprised of upper mold section and female die, the outer rim of described upper mold section and female die is provided with dowel hole and the fixing screw hole of using, and described dowel hole is with fixing symmetrical along the upper mold section outer marginal circumference with screw hole.
In order to realize being located by connecting more accurately, described dowel hole is with fixing symmetrical spaced apart in six position of halving of outer marginal circumference with screw hole.
The advantage of technical scheme provided by the utility model is, middle mould is divided into upper mold section and female die, and two parts mould can adopt separately the processing of slow wire feeding processing mode, has guaranteed the uniformity of mold integral precision.Outer rim symmetry at upper mold section and female die is offered dowel hole and fixed screw holes, so that upper and lower half module when combination integrated positioning is accurate.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is top view of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with embodiment, but not as to restriction of the present utility model.
As shown in Figure 1 and Figure 2, mould is comprised of upper mold section 1 and female die 2 in the step, described upper mold section 1 is provided with dowel hole 3 and fixing with screw hole 4 with the outer rim of female die 2, and described dowel hole 3 is with fixing symmetrical spaced apart in six position of halving of outer marginal circumference with screw hole 4.Middle mould is divided into upper mold section and female die, and two parts mould can adopt separately the processing of slow wire feeding processing mode, has guaranteed the uniformity of mold integral precision.Outer rim symmetry at upper mold section and female die is offered dowel hole and fixed screw holes, so that upper and lower half module when combination integrated positioning is accurate.
