Abstract

The utility model discloses a vertical runner mechanism applied to a mold. The vertical runner mechanism comprises a dispensing port, a vertical runner and a vertical runner insert core, wherein the dispensing port is used for charging glue to the surfaces of products; the vertical runner is formed into a female mold core of the mold, and is vertically communicated with the dispensing port; the vertical runner insert core is arranged in the female mold core of the mold, and is provided with an empty cavity vertically communicated with the vertical runner. According to the vertical runner mechanism provided by the utility model, the vertical runner insert core with the empty cavity is embedded into the female mold core and is simple to process, and the length of the vertical runner in the female mold core is reduced, so that the vertical runner is controlled to be extremely short, the electrode discharge time and the electrode loss are lowered, and the mold cost is saved.

Description

Perpendicular runner mechanism

[technical field]

The utility model relates to a kind of mold mechanism, is specifically related to a kind of for the perpendicular runner mechanism by melt plastic cement.

[background technology]

When plastic mould advances glue, often adopt some Jiao Kou to advance glue, some Jiao Kou has the following advantages: automatically cut off, can directly advance glue to product surface, and the residual remaining glue in Jiao Kou place is less, need not post processing etc. after shaped article.Therefore, some Jiao Kou uses very extensive.

See also Figure 1 and Figure 2, the perpendicular runner mechanism of prior art, be applied in mould, this mould comprises caster 10, male model plate 20, mother module core 11 and male die core 21, the perpendicular runner mechanism of the prior art comprises a glue mouth 30 and the perpendicular runner 40 that is connected with some glue mouth 30, and this perpendicular runner 40 forms by electrode discharge.When shaped article 50, the plastic cement of melting injects die cavity shaped article 50 by perpendicular runner 40 and some glue mouth 30.

Yet due to the restriction of product 50 structures, perpendicular runner 40 length are very long sometimes, need extremely long discharge time, and larger to export license, are unfavorable for controlling the cost of mould, and are unfavorable for shortening the process time of mould.

In view of this, be necessary to develop in fact a kind of perpendicular runner mechanism, need extremely long discharge time and the larger problem of export license to solve when perpendicular runner is long.

[summary of the invention]

Therefore, the purpose of this utility model is to provide a kind of perpendicular runner mechanism, and this perpendicular runner mechanism can overcome perpendicular runner needs extremely long discharge time and the larger defective of export license when long.

In order to achieve the above object, perpendicular runner mechanism of the present utility model is applied in mould, and this mould comprises caster, male model plate, mother module core and male die core, and take mould die sinking direction as vertical direction, this perpendicular runner mechanism comprises:

Point Jiao Kou, it advances glue to product surface;

Perpendicular runner, it is opened in the mother module core of mould, and this perpendicular runner vertically is communicated with described some Jiao Kou;

Perpendicular runner enters son, and it is located in the mother module core of mould, and this perpendicular runner enters son and is provided with cavity and vertically is communicated with described perpendicular runner.

Especially, being provided with corresponding spatial accommodation in described mother module core enters sub located therein for perpendicular runner.

Especially, on vertical direction, the length of described perpendicular runner enters the length of son less than perpendicular runner.

Compared to prior art, perpendicular runner mechanism of the present utility model, enter son by perpendicular runner with cavity of edge in the mother module core of mould, should enter son processing simply by perpendicular runner, thereby shortened the perpendicular flow channel length in the mother module core, the length of perpendicular runner is controlled in extremely short length, has reduced the loss of electrode discharge time and electrode, saved die cost.

[specific embodiment]

See also Fig. 3 and shown in Figure 4, wherein Fig. 3 has illustrated the structural representation of the perpendicular runner mechanism of the utility model, and Fig. 4 has illustrated the partial enlarged drawing of Fig. 3.

Perpendicular runner mechanism of the present utility model is applied in mould, and this mould comprises caster 100, male model plate 200, mother module core 110 and male die core 210, and take mould die sinking direction as vertical direction, this perpendicular runner mechanism comprises:

Point glue mouth 300, it advances glue to product 500 surfaces;

Perpendicular runner 400, it is processed by electrode discharge, and this perpendicular runner 400 is opened in the mother module core 110 of mould, and should vertically be communicated with described some glue mouth 300 by perpendicular runner 400;

Perpendicular runner enters son 600, it is located in the mother module core 110 of mould, being provided with corresponding spatial accommodation in described mother module core 110, to enter son for perpendicular runner 600 located therein, should perpendicular runner entering son 600 is provided with cavity 610 and vertically is communicated with described perpendicular runner 400, the mode moulding that this cavity 610 can cut by line, can also be by the mode moulding of boring, on vertical direction, the length of described perpendicular runner 400 enters the length of son 600 less than this perpendicular runner.

When moulding product 500, the injection machine that is connected with mould injects the plastic cement of melting in the mould, the plastic cement of melting flow into perpendicular runner and enters in son 600, then the plastics of this melting flow to perpendicular runner 400 and some glue mouth 300 by the cavity 610 that perpendicular runner enters on son 600, be injected at last in the die cavity of mould shaped article 500.

Perpendicular runner mechanism of the present utility model has been inlayed a perpendicular runner with cavity 610 and has been entered son 600 in mother module core 110.Compare with the perpendicular runner 400 of discharge processing on mother module core 110, enter to offer on son 600 cavity 610 processing simply, fast at this perpendicular runner, should enter the length that son 600 has shortened perpendicular runner 400 in mother module core 110 by perpendicular runner, the length of perpendicular runner 400 is controlled in extremely short length, reduce the loss of electrode discharge time and electrode, saved die cost.
