Abstract
The invention discloses a split mould, aiming at solving the problem that a workpiece can not be molded by pressing for once in the prior art. The split mould comprises a mould sleeve, a limiting ring fixed at the upper end of the mould sleeve, a fastening device sheathed on the outer side wall of the mould sleeve, and a back pressure pad arranged at the lower end of the mould sleeve, wherein the mould sleeve is a circular tube formed by splicing two semi-circular tubes or three one-third circular tubes; a center hole of the mould sleeve is internally provided with a mold core which is arranged together with the mould sleeve in a coaxial way; an upper punch and a lower punch are sequentially sheathed and connected to the mold core from top to bottom; an inner cavity is formed between the upper punch and the lower punch, and the shape of the inner cavity is the same as that of the workpiece; the inner side wall of the mould sleeve is provided with a convex ring matched with a groove of the workpiece. The mould sleeve is the circular tube formed by splicing the two semi-circular tubes or the three one-third circular tubes, and the workpiece can be molded by pressing for once when being processed, so that the processing efficiency is high; furthermore, the split mould is simple in processing, saves the raw material, and is low in processing cost, lower in error and high in accuracy of the processed workpiece.
Description
Technical field
The present invention relates to a kind of mould, relate in particular to a kind of Split mold.
Background technology
At present, because the mould of integral type can not take off the workpiece processed, add and need to divide man-hour a plurality of steps to be processed, the processing of workpiece, need compressing several times, working (machining) efficiency is low, and processed complex, and wastage of material is serious, processing cost is higher, through repeatedly processing, error is larger, and the workpiece accuracy processed also reduces accordingly.
Summary of the invention
The invention provides a kind of Split mold, be intended to solve the problem that in prior art, workpiece can not be once compressing.
In order to solve above technical problem, the present invention is achieved through the following technical solutions: a kind of Split mold, comprise die sleeve, be fixed on the spacing collar of die sleeve upper end, be enclosed within the fastener on the die sleeve lateral wall, be positioned at the counter-pressure cushion of die sleeve lower end, described die sleeve is by two semi-circular tubes or three pipes that 1/3rd pipes are spliced, be provided with the core coaxial with die sleeve in the centre bore of described die sleeve, described core is socketed with upper punch and undershoot from the top down successively, form the shape inner chamber identical with workpiece between described upper punch and undershoot, described die sleeve madial wall is provided with the bulge loop that the groove with workpiece matches.
Further, described fastener is comprised of equal semi-circle tubular anchor ears with two ears, for the splicing part by die sleeve, is fixed together.
Further, described two anchor ears are fixed on die sleeve by bolt and nut, are convenient to the fastening of semi-circular tube anchor ear.
Further, the lateral wall of described die sleeve is provided with certain gradient, described fastener is the fastening annulus 3 that a madial wall gradient is identical with die sleeve lateral wall gradient, and described fastener madial wall and die sleeve lateral wall middle part match, and for the splicing part by die sleeve, are fixed together.
Further, described die sleeve is spliced by the pipe of three 1/3rd, is convenient to the dismounting of die sleeve.
Further, described spacing collar is fixed together by magnetic force and die sleeve, is convenient to spacing collar and die sleeve is fixed together.
Compared with prior art advantage of the present invention is: die sleeve of the present invention is by two semi-circular tubes or three pipes that 1/3rd pipes are spliced, the processing of workpiece, only need once suppress just plastic, working (machining) efficiency is high, and processing is simple, conservation, processing cost is low, error is less, and the workpiece accuracy processed is high.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described:
The structural representation that Fig. 1 is the embodiment of the present invention one;
The structural representation that Fig. 2 is the embodiment of the present invention two;
The structural representation that Fig. 3 is 1/3rd pipes in the embodiment of the present invention one.
The specific embodiment
Embodiment mono-:
Consult Fig. 1 and Fig. 3, a kind of Split mold, comprise die sleeve 1, be fixed on die sleeve 1 upper end spacing collar 2, be enclosed within fastener on die sleeve 1 lateral wall, be positioned at the counter-pressure cushion 6 of die sleeve 1 lower end, the pipe of described die sleeve 1 for being spliced by three 1/3rd pipes, be provided with the core 7 coaxial with die sleeve 1 in the centre bore of described die sleeve 1, described core 7 is socketed with upper punch 5 and undershoot 4 from the top down successively, form the shape inner chamber identical with workpiece 8 between described upper punch 5 and undershoot 4, described die sleeve 1 madial wall is provided with the bulge loop 11 that the groove with workpiece 8 matches; Described fastener is comprised of equal semi-circle tubular anchor ears 9 with two ears; Described two anchor ears 9 are fixed on die sleeve 1 by bolt and nut; Described spacing collar 2 is fixed together by magnetic force and die sleeve 1.
While installing and using, core 7 is passed to workpiece 8, three 1/3rd cylinders are stitched together and form die sleeve 1, undershoot 4 is socketed in to the lower end of core 7, core 7 is inserted in the centre bore of die sleeve 1, the raw material that adds workpiece, upper punch 5 is socketed on core 7,, two anchor ears, 9 use bolt and nuts are fixed with two anchor ears 9 by 1 armful of the die sleeve that is stitched together together, made the logical magnetic of spacing collar 2, be adsorbed on die sleeve 1, counter-pressure cushion 6 is arranged on to the lower end of die sleeve 1, workpiece 8, under the Split mold effect, processes required form; Make spacing collar 2 demagnetizations, spacing collar 2 is taken off, then take off bolt and nut, anchor ear 9 is taken off, open die sleeve 1, take off workpiece 8.
Embodiment bis-:
Consult Fig. 2, with the difference of embodiment mono-, be: the lateral wall of described die sleeve 1 is provided with certain gradient, described fastener is the fastening annulus 3 that a madial wall gradient is identical with die sleeve 1 lateral wall gradient, and described fastening annulus 3 madial walls and die sleeve 1 lateral wall middle part match; During installation, fastening annulus 3 is enclosed within to the die sleeve 1 spliced, fastening annulus 3 is pressed down, under the effect on slope, that die sleeve 1 is fastening.
