Description

A kind of novel die

Technical field

The utility model is related to mould applications, and in particular to a kind of novel die.

Background technology

In mould production process, last link of each cyclic process of injection mo(u)lding is by moulding and cast System condensate is deviate from from mould, and the mechanism that this operation is realized in a mold is referred to as mold ejection mechanism.

Due to the particularity of some shape of products, need to carry out multi-stage stepped top when the die sinking after the completion of injection is ejected Go out, this requires that the ejecting mechanism of mould is multisection type ejecting mechanism.But, mould multisection type ejecting mechanism is complex, and The size and weight of mould can be increased, cause the production cost of mould higher, and carrying and the opening and closing mold process of inconvenient mould. Accordingly, it would be desirable to be improved to the multisection type ejecting mechanism of mould, simplify structure and reduce its size.

Utility model content

The purpose of this utility model is：A kind of novel die is provided, the multisection type ejecting mechanism of mould is simplified, is realized little Type.

To achieve these goals, the utility model provides following technical scheme：

A kind of novel die, including die ontology, return pin, lock core, briquetting and guide post；The die ontology include from Top board, upper bolster, upper die plate, lower template, die shoe, backing plate and the base plate of arrangement, the return pin bottom are up to sequentially overlapped down End and pad contact, through lower template and die shoe, the return pin upper end is provided with cushion block, the lock on the return pin top One end of core contacts with the annular groove on return pin, and the other end is contacted with the guide post being vertically arranged, and the briquetting is located at lock Core lower section.

Further, the guide post upper end is provided with staged chute, and the transition position of staged chute is arc, described Lock core is contacted with the staged chute on guide post.

Further, the cushion block upper end contacts with upper die plate, and the cushion block is connected by screw with return pin.

Further, the lock core lower end contacts with briquetting, and lock core and the perpendicular angular cross of briquetting.

The beneficial effects of the utility model are：The multisection type ejecting mechanism of novel die relatively before same mechanism simplify The structure of parts, and miniaturization is realized, the mould before solving accommodates multisection type ejecting mechanism and amplifies Problem, the consumption of raw metal when can reduce production mould reduces the production cost of mould, while reducing the entirety weight of mould Amount so as to convenient to carry and be opened and closed mold process, reduces the labour intensity of direct labor, and improve production efficiency.

Description of the drawings

Fig. 1 is a kind of internal structure schematic diagram of novel die of the utility model.

Specific embodiment

In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing and enforcement Example, the utility model is described in further detail.It should be appreciated that specific embodiment described herein is only to explain this Utility model, is not used to limit the utility model.

With reference to Fig. 1, a kind of novel die, including die ontology, return pin 8, lock core 10, briquetting 11 and guide post 12；Institute Stating die ontology includes being sequentially overlapped top board 1, upper bolster 2, upper die plate 3, lower template 4, die shoe 5, the pad of arrangement from top to bottom Plate 6 and base plate 7, the bottom of return pin 8 contacts with backing plate 6, and the top of return pin 8 is through lower template 4 and die shoe 5, institute State the upper end of return pin 8 and be provided with cushion block 9, one end of the lock core 10 contacts with the annular groove on return pin 8, annular groove position In the top of return pin 8 at cushion block 9, the other end is contacted with the guide post 12 being vertically arranged, and the briquetting 11 is located at lock core 10 Lower section.

The upper end of the guide post 12 is provided with staged chute, and the transition position of staged chute is arc, the lock core 10 Contact with the staged chute on guide post 12.

The upper end of the cushion block 9 contacts with upper die plate 3, and the cushion block 9 is connected by screw with return pin 8.

The lower end of the lock core 10 contacts with briquetting 11, and lock core 10 and the perpendicular angular cross of briquetting 11, the briquetting 11 For supporting lock core 10, while the forms of motion of lock core 10 can be limited as linear motion.

Annular groove on return pin 8 is used to pin lock core 10, the lock core 10 by with guide post 12 on staged Chute coordinates to limit the linear motion up and down of guide post 12.

Above-described embodiment is used to be further described the utility model, but the utility model is not confined to into these Specific embodiment.All any modification, equivalent and improvement made within spirit of the present utility model and principle etc., It is interpreted as within protection domain of the present utility model.
