Abstract
The utility model discloses one and certainly can tear flash mold structure open by auxiliary exhaust, comprise plate in die cavity upper plate, die cavity, die cavity lower plate; In described die cavity upper plate, die cavity, plate, die cavity lower plate are superimposed together successively, the forming recess of product is formed between plate in die cavity upper plate and die cavity, multiple small-sized cores on die cavity upper plate respectively gap penetrate in the multiple small cavity in die cavity on plate, form the apopore of product, be communicated with a reverse taper holes in the bottom surface of small cavity, this reverse taper holes forms the stub bar of falling infundibulate.During due to the utility model injection moulding, the air of product delivery port is extruded in reverse taper holes along the bottom delivery port of small cavity, and it is bad that the delivery port of product does not have air residual would not produce tired gas.After shaping, because stub bar is in falling funnel structure, up-small and down-big, the stub bar that stub bar is positioned at delivery port can rupture from the delivery port position of product with the stub bar being positioned at reverse taper holes, and stay plate in die cavity, the product after taking-up does not have stub bar.
Description
Technical field
The utility model relates to a kind of rubber product molding mould, and particularly relating to one can tear flash mold structure open by auxiliary exhaust certainly.
Background technology
As shown in Figure 2, bathroom nozzle (as shown in Figure 1) rubber product 10 faucet mould structure, generally be made up of upper strata cavity plate 1 ' and lower floor's cavity plate 2 ', such mould structure, the flowing of sizing material in production process, air is finally extruded into the delivery port of product 10 ' and forms water outlet burr head stub bar 101 ', product is caused to be stranded gas bad, must extending cure time, to solve tired gas bad, in addition, product 10 ' is after taking-up, water outlet burr head stub bar 101 ' can be retained in above product 10 ', rear road adds man-hour, water outlet burr head stub bar 101 ' must be removed one by one by hand, hardness ag(e)ing is low.
Summary of the invention
The purpose of this utility model be to provide a kind of production efficiency high can auxiliary exhaust from tear flash mold structure open.
For achieving the above object, technical solution of the present utility model is:
The utility model is that one can tear flash mold structure open by auxiliary exhaust certainly, comprises plate in die cavity upper plate, die cavity, die cavity lower plate; In described die cavity upper plate, die cavity, plate, die cavity lower plate are superimposed together successively, the forming recess of product is formed between plate in die cavity upper plate and die cavity, multiple small-sized cores on die cavity upper plate respectively gap penetrate in the multiple small cavity in die cavity on plate, form the apopore of product, be communicated with a reverse taper holes in the bottom surface of small cavity, this reverse taper holes forms the stub bar of falling infundibulate.
On described die cavity upper plate, small-sized core is back taper; Small cavity in described die cavity on plate is bellmouth.
Die cavity lower plate offers annular elongated slot, and this annular elongated slot is located at immediately below multiple reverse taper holes.
After adopting such scheme, because the utility model is primarily of plate, die cavity lower plate composition in die cavity upper plate, die cavity, in die cavity, the bottom surface of the small cavity of plate is communicated with a reverse taper holes, and this reverse taper holes forms the stub bar of falling infundibulate.During injection moulding, the air of product delivery port is extruded in reverse taper holes along the bottom delivery port of small cavity, and it is bad that the delivery port of product does not have air residual would not produce tired gas.After shaping, because stub bar is in falling funnel structure, up-small and down-big, the stub bar that stub bar is positioned at delivery port can rupture from the delivery port position of product with the stub bar being positioned at reverse taper holes, and stay plate in die cavity, the product after taking-up does not have stub bar.
Below in conjunction with the drawings and specific embodiments, the utility model is further described.

Fig. 2 is the bathroom nozzle injection mould schematic diagram commonly used;
Fig. 3 is schematic diagram of the present utility model;
Fig. 4 is three-dimensional exploded view of the present utility model;

Detailed description of the invention
As shown in Figure 3-Figure 5, the utility model is that one can tear flash mold structure open by auxiliary exhaust certainly, comprises plate 2 in die cavity upper plate 1, die cavity, die cavity lower plate 3.
In described die cavity upper plate 1, die cavity, plate 2, die cavity lower plate 3 are superimposed together successively, the forming recess of product is formed between plate 2 in die cavity upper plate 1 and die cavity, multiple back taper small-sized cores 11 on die cavity upper plate 1 respectively gap penetrate in the multiple small cavity 21 in die cavity on plate 2, the apopore 101 of formation product and column 102(are as shown in Figure 1), described small cavity 21 is bellmouth, be communicated with a reverse taper holes 23 at underrun delivery port 22 of small cavity 21, this reverse taper holes 23 can form the stub bar of falling infundibulate.Die cavity lower plate 3 is offered annular elongated slot 31, this annular elongated slot 31 is located at immediately below multiple reverse taper holes 23, the stub bar clamp-oned in multiple reverse taper holes 23 is joined together, after product takes off from mould, the stub bar remained in die cavity lower plate 3 is together in series, stub bar full wafer can be taken out, facilitate stub bar to remove.
The utility model production process:
1. when sizing material is emitted in the die cavity of plate 2 in die cavity, move on to pressurization in board, sizing material after pressurized is to the interstitial flow in mold cavity, air in die cavity is discharged simultaneously, the air of product 10 delivery port is extruded in reverse taper holes 23 along the bottom delivery port 22 of small cavity, and it is bad that the delivery port of product 10 does not have air residual would not produce tired gas.
2. after product 10 arrives the cure time of setting, shift out mold machine table, open the die cavity upper plate 1 of patrix, with Compressed Gas blowout product 10, because stub bar 103 is in funnel structure is up-small and down-big, the stub bar 1031 that stub bar 103 is positioned at delivery port 22 can rupture from delivery port 22 position of product with the stub bar 1032 being positioned at reverse taper holes 23, and stay plate 2 in die cavity, the product 10 after taking-up does not have stub bar.
Emphasis of the present utility model is just: adopt three ply board mould structure, meanwhile, delivery port is communicated with a reverse taper holes structure.
The above, be only the utility model preferred embodiment, therefore can not limit with this scope that the utility model implements, the equivalence namely done according to the utility model claim and description change with modify, all should still belong in scope that the utility model patent contains.
