Abstract
The utility model discloses an injection mold's flash well structure is assisted to gas, the flash well has been seted up in the mould, the flash import, the air flue export, the flash well, the flash import, gas is assisted flash guiding groove gentleness and is said that the export feeds through in proper order, flash guiding groove intercommunication is assisted with gas to the air flue export, be equipped with the pneumatic cylinder in the mould, the telescopic link of pneumatic cylinder is connected with the sealed needle valve of flash, the front end of the sealed needle valve of flash lies in gas and assists between the export of flash guiding groove gentleness way, can be sealed with blocking between the export of gas assistance flash guiding groove gentleness way, be equipped with the ejector pin in the mould, the front end of ejector pin links to each other with the flash well. When moulding plastics hollow pipe fitting, block sealedly between the front end of the sealed needle valve of flash exports gas assistance flash guiding groove gentleness way. After moulding plastics, incomplete of forming in the flash well is ejecting by the ejector pin. Because the sealed needle valve of flash cuts with the injection molding and between incomplete, and need not repair and cut the injection molding.
Description
Technical field
The utility model relates to injection mold field, particularly a kind of overflowing well structure of gas-assisted injection molding mould.
Background technology
The patent No. is 201320066236.6, and disclose the utility model patent of a kind of " gas-assisted injection molding mould exhaust mechanism " by name, its Problems existing is: 1, only possess disappointing function, can not meet the requirement that overflowing well dimension process regulates; 2, do not provide overflowing well synchronously to eject and repair butt case with automation.
Summary of the invention
The purpose of this utility model is exactly for the problems referred to above, and provides a kind of overflowing well structure of gas-assisted injection molding mould.
The utility model is in mould, offer overflowing well, flash import, air passage outlet, overflowing well, flash import, the auxiliary flash guiding groove of gas are communicated with successively with air passage outlet, air passage outlet is communicated with the auxiliary flash guiding groove of gas, hydraulic cylinder is provided with in mould, the expansion link of hydraulic cylinder is connected with flash sealing needle-valve, the front end of flash sealing needle-valve is between the auxiliary flash guiding groove of gas and air passage outlet, sealing can be blocked by between auxiliary for gas flash guiding groove and air passage outlet, be provided with push rod in mould, the front end of push rod is connected with overflowing well.
The course of work of the present utility model:
When the pipe fitting of injection moulding hollow, the powder be blown in the middle of pipe fitting enters overflowing well successively from air passage outlet, the auxiliary flash guiding groove of gas and flash import, blow after material terminates, hydraulic cylinder drives flash sealing needle-valve to move forward, sealing, between the auxiliary flash guiding groove of gas and air passage outlet, is blocked by between auxiliary for gas flash guiding groove and air passage outlet in the front end of flash sealing needle-valve 7.After injection moulding terminates, residual that is formed in overflowing well is ejected by push rod.Because flash sealing needle-valve blocks between moulding and residual, and need not repair and cut moulding.
The beneficial effects of the utility model:
1, the utility model can provide flash function in Gas assisted injection moulding process, and can carry out flash cavity size adjustment according to actual process demand.
2, the utility model can realize flash structure and independently ejects, and gripping apparatus can be utilized to carry out automatic capturing, can realize industrial automation and produce.
3, the present invention is when mould ejects product, can synchronously and excise flash structure, realizes and being automatically separated of product.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is close-up schematic view of the present utility model.
Detailed description of the invention
Refer to shown in Fig. 1 and Fig. 2, the present embodiment offers overflowing well 2 in mould 1, flash import 3, air passage outlet 4, overflowing well 2, flash import 3, the auxiliary flash guiding groove 5 of gas is communicated with successively with air passage outlet 4, air passage outlet 4 is communicated with the auxiliary flash guiding groove 5 of gas, hydraulic cylinder 6 is provided with in mould 1, the expansion link of hydraulic cylinder 6 is connected with flash sealing needle-valve 7, the front end of flash sealing needle-valve 7 is between the auxiliary flash guiding groove 5 of gas and air passage outlet 4, sealing can be blocked by between auxiliary for gas flash guiding groove 5 and air passage outlet 4, push rod 8 is provided with in mould 1, the front end of push rod 8 is connected with overflowing well 2.
The course of work of the present embodiment:
When the pipe fitting of injection moulding hollow, the powder be blown in the middle of pipe fitting enters overflowing well 2 successively from air passage outlet 4, the auxiliary flash guiding groove 5 of gas and flash import 3, blow after material terminates, hydraulic cylinder 6 drives flash to seal needle-valve 7 and moves forward, sealing, between the auxiliary flash guiding groove 5 of gas and air passage outlet 4, is blocked by between auxiliary for gas flash guiding groove 5 and air passage outlet 4 in the front end of flash sealing needle-valve 7.After injection moulding terminates, residual that is formed in overflowing well 2 is ejected by push rod 8.Because flash sealing needle-valve 7 blocks between moulding and residual, and need not repair and cut moulding.
