Abstract

The utility model discloses a mould with an injection redundancy cavity. The mould with the injection redundancy cavity is composed of an upper mould body (3) and a lower mould body (6), and a concave cavity of the lower mould body (6) is a lower mould cavity (8). The mould with the injection redundancy cavity is characterized in that the upper mould body is provided with a wedge-shaped positioning upper plane and a plane seal mould plane, the inner side of a lower mould wedge-shaped positioning device (10) is provided with continuous rows of bean-point-shaped remaining material storage cavities (9), the remaining material storage cavities (9) are located on the upper plane of the lower mould body (6) and are communicated with mould cavity bodies through overflowing channels (11), and the remaining material storage cavities (9) are independent and disconnected. Due to the fact that the remaining material storage cavities are pre-reserved at the edge of the mould, excess foaming materials flow into the pre-reserved cavities under pressure and do not overflow, beauty and integrity of a product are improved, workload of subsequent processing procedure is saved, and the design and the device which are practical, saving, reliable and efficient are provided.

Description

A kind of mould with the redundant cavity of material feeding

Technical field:

The utility model relates to the technology of die manufacturing field, is a kind of mould with the redundant cavity of material feeding specifically, is applicable to that raw material is the mould molding goods of stickiness pulpous state wet feed, and particularly biomass full degradable industry buffering package goods are used mould.

Background technology:

For the raw material of mould molding goods is stickiness pulpous state wet feed; Like the raw material of biomass full degradable industry buffering package goods, be with straw fiber and starch, in addition auxiliary adjustment agent; Through the synthetic a kind of stickiness pulpous state wet feed of special process; Pump into material in the die cavity with the automation feeding device, because the density and the volume (weight) of the pulpous state wet feed that the material loading metering cylinder is got have certain error (± 5%) at every turn, what adopt is starch foaming technology in addition; The material that has more in the entering die cavity will go out die shape in the pressure underflow and become burr, thereby influences the attractive in appearance and complete of product.

Summary of the invention:

The purpose of the utility model is the deficiency that overcomes above-mentioned prior art; And a kind of mould with the redundant cavity of material feeding is provided; Be prone to when mainly solving existing mould and being raw material mould molding goods form burr, influence the problem such as attractive in appearance and complete of product with stickiness pulpous state wet feed.

The technical scheme of the utility model is: a kind of mould with the redundant cavity of material feeding, and it is made up of upper die body and lower mold body, establishes patrix steam discharge steam passage on the upper die body; Set mould steam discharge steam passage on the lower mold body; Lower mold body is a die, and cavity is the counterdie die cavity, establishes steam discharge vapour line in the lower mold body; Its special character is on lower mold body, to set die wedge shape positioner and lower plane envelope mould plane; It is corresponding that envelope mould plane, plane is gone up in wedge shape location on the end face of counterdie wedge shape positioner and the upper die body, and the two cooperates and constitutes wedge shape automatic positioning equipment, and it is corresponding that the mould plane is sealed on lower plane envelope mould plane and the last plane on the upper die body; Establish the clout of platoon beans point shape in the inboard of counterdie wedge shape positioner and retain cavity; Clout is retained the last plane that cavity is positioned at lower mold body, and clout is retained cavity and communicated with the die cavity main body through the flash passage, and it is independent continuous that clout is retained cavity.

Further, said clout is retained cavity depth 2 ㎜, and the cross section is semicircle.

One step of ground, described flash channel depth is 0.1～0.15 ㎜.

Compared with present technology a kind of mould with the redundant cavity of material feeding of the utility model has following good effect: 1, adopt the redundant cavity of material feeding on the mould; Add unnecessary material is collected in the redundant cavity of material feeding through the flash passage when foamable; The density and the volume that have thoroughly solved the pulpous state wet feed that the material loading metering cylinder gets at every turn have certain error; Make the material that has more in the entering die cavity go out the problem that die shape becomes burr in the pressure underflow; Thereby reduced to automatic charging device manufacture and design requirement and complexity, reduced the device fabrication cost, enlarged the redundancy of mould material feeding; 2, moulded products is complete, attractive in appearance, has reduced semi-finished product post processing workload, has improved the moulding qualification rate of product; 3, mould is practical, simple, and difficulty of processing is little, good forming effect.

Description of drawings:

Fig. 1 is the structural representation of the utility model;

Fig. 2 is the vertical view of the lower mold body of the utility model;

Fig. 3 is the A-A cut-away view of Fig. 2.

The specific embodiment:

In order to understand better and to implement, provide specific embodiment below in conjunction with accompanying drawing and specify the utility model.

Embodiment 1, referring to Fig. 1,2,3, is processed into upper die body 3 and lower mold body 6 according to product design, and lower mold body 6 is a die, and cavity is a counterdie die cavity 8, is moulded products 5 between reinforced back upper die body 3 and the lower mold body 6; Be processed with patrix steam discharge steam passage 4, wedge shape location upward envelope mould plane 12, plane and envelope mould plane, last plane 2 on the upper die body 3; Be processed with counterdie steam discharge steam passage 7, steam discharge vapour line 14, counterdie wedge shape positioner 10 and lower plane envelope mould plane 13 on the lower mold body 6; It is corresponding that envelope mould plane 12, plane is gone up in the end face of counterdie wedge shape positioner 10 and wedge shape location, and the two cooperates and constitutes wedge shape automatic positioning equipment 1 during matched moulds, and lower plane envelope mould plane 13 is corresponding with envelope mould plane 2, last plane, and the two cooperates and seals mould during matched moulds; Clout in the inboard of counterdie wedge shape positioner 10 processing platoon beans point shape is retained cavity 9; Clout is retained cavity 9 degree of depth 2 ㎜; The cross section is semicircle, and clout is retained the last plane that cavity 9 is positioned at lower mold body 6, and clout is retained cavity 9 and communicated with the die cavity main body through flash passage 11; Flash passage 11 degree of depth are 0.1～0.15 ㎜, and it is independent continuous that each clout is retained cavity 9.

The described a kind of mould with the redundant cavity of material feeding of the utility model is during the machine-shaping goods, owing to side seal mould plane in plane on the wedge shape positioner and the mould has closing function simultaneously concurrently; Can guarantee the die cavity back reliable envelope mould that feeds intake, make to produce enough pressure in the die cavity and make the material uniform in foaming, consistent in density; After the material foaming is full of the complete moulding of whole die cavity goods; Unnecessary material is collected in the retention cavity through the flash passage when foamable, because the redundant cavity of material feeding plane on counterdie, upper mould is a plane; Material in the redundant cavity of tight closure material feeding continues excessive and all stays in cavity; Accomplish the processing of unnecessary material, guaranteed the integrality of goods, expanded the error redundancy that mould carries.
