Abstract

The utility model discloses a core pulling type mold. The core pulling type mold comprises an upper mold plate and a lower mold plate, wherein the lower end of the upper mold plate is connected with an upper cushion plate, the lower end of the upper cushion plate is connected with an upper mold, supporting plates are symmetrically arranged on the lower mold plate, the supporting plates are arranged at the front and the back, the upper end of the lower mold plate is connected with a lower cushion plate, the upper end of the lower cushion plate is connected with a lower mold, a top plate is arranged between the supporting plates on the lower mold plate, a top rod is arranged on the top plate, a movable insert is mounted on the lower mold, the movable insert and the lower mold form a split structure, an insert mold core is connected on the movable insert in a threaded manner, the insert mold core is in threaded connection with an insert, and an insert top rod is arranged on the top plate. The lower mold of the core pulling type mold and the movable insert form the split structure, so that the core pulling type mold has the advantages of convenience in manufacturing and low cost; once the insert is damaged, only the insert needs to be replaced, so that the maintenance cost is reduced; and in addition, as for a product pressed by adopting the core pulling type mold with the structure, no drilling material exists in the insert, wire withdrawing treatment is not required, the quality of the product is improved, and the structure is simple and easy to realize.

Description

A kind of core-pulling type mold

Technical field

The utility model relates to a kind of core-pulling type mold.

Background technology

In the Design of Dies field, the goods for adding inserts and inserts and be positioned at the side in forming process generally utilize core-pulling mechanism to come moulding to finish.Yet, existing core-pulling type mold, its complex structure, the inserts core passes mold insert and the inserts threaded engagement on the counterdie, and its mold insert and counterdie are structure as a whole, this kind structure, not only cost is high, and mold insert is fragile in repeating the process of constantly loosing core, in case damage, need to change whole mould, in addition, this kind structure easily causes bores material in the inserts, process so that need to carry out hard waste with screw tap behind the product molding, cumbersome, and strengthened workload.

The utility model content

The purpose of this utility model is for the problems referred to above, and a kind of core-pulling type mold is provided, and is structure as a whole with mold insert and the counterdie that solves existing core-pulling type mold, easily bores the problem of material in the inserts, and die cost is high, flimsy problem.

The purpose of this utility model is to be achieved through the following technical solutions:

A kind of core-pulling type mold, comprise cope match-plate pattern, lower bolster, the lower end of described cope match-plate pattern is connected with upper padding plate, the lower end of described upper padding plate is connected with patrix, be symmetrically arranged with supporting plate on the described lower bolster, arrange before and after the described supporting plate, its upper end is connected with lower bolster, the upper end of described lower bolster is connected with counterdie, between supporting plate, be provided with top board on the described lower bolster, be provided with on the described top board be used to the push rod that ejects goods, on the described counterdie movable insert is installed, described movable insert and counterdie are split-type structural, and the inserts core that has been threaded on the movable insert, described inserts core is threaded with inserts, is provided with on the described top board be used to the mold insert push rod that ejects movable insert.

The beneficial effects of the utility model are, the counterdie of described a kind of core-pulling type mold and movable insert are split-type structural, and be easily manufactured, cost is low, in case and mold insert damage, only needing to change mold insert gets final product, reduce maintenance cost, in addition, adopted the goods of the core-pulling type mold compacting of this kind structure, expect without boring in its inserts, need not to carry out hard waste and process, improved the quality of goods, simple in structure, be easy to realize.

The specific embodiment

Further specify the technical solution of the utility model below in conjunction with accompanying drawing and by the specific embodiment.

Please refer to Figure 1 and Figure 2, Fig. 1 is the structural representation of a kind of core-pulling type mold of the utility model; Fig. 2 is that a kind of core-pulling type mold shown in Figure 1 is at the enlarged drawing at A place; In present embodiment, a kind of core-pulling type mold, comprise cope match-plate pattern 1, lower bolster 7, the lower end of described cope match-plate pattern 1 is connected with upper padding plate 2, the lower end of described upper padding plate 2 is connected with patrix 3, be symmetrically arranged with supporting plate 5 on the described lower bolster 7, described supporting plate 5 front and back are arranged, its upper end is connected with lower bolster 14, the upper end of described lower bolster 14 is connected with counterdie 4, between supporting plate 5, be provided with top board 6 on the described lower bolster 7, be provided with on the described top board 6 be used to the push rod 8 that ejects goods 13, on the described counterdie 4 movable insert 10 is installed, described movable insert 10 is split-type structural with counterdie 4, and the inserts core 11 that has been threaded on the movable insert 10, described inserts core 11 is threaded with inserts 12, is provided be used to the mold insert push rod 9 that ejects movable insert 10 on the described top board 6.

During work, inserts core 11 is packed in the movable insert 10, then inserts 12 is screwed on the inserts core 11, require inserts 12 clampings firm, the inserts 12 surfaces movable insert 10 of fitting fully, after assembling, with integral installation on counterdie 4, in mould, carry out the compacting of goods 13, after goods 13 moulding, by push rod 8 and mold insert push rod 9 with movable insert 10 along with goods 13 together break away from moulds, inserts core 11 inserts 12 of back-outing, reload the compacting of carrying out next goods 13 in the counterdie 4 with inner hexagon spanner.

Above embodiment has just set forth basic principle of the present utility model and characteristic; the utility model is not limited by above-described embodiment; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various variations and change, and these variations and change all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
