The utility model discloses a vacuum -exhaust's structure, the product that can prevent sealed chamber produces the problem of flash in injection molding process.
Description
Technical field
This utility model is related to technical field of mold, more particularly, to a kind of suction vacuum exhaust structure.
Background technology
Due to the industries such as automobile, building, household electrical appliance, food, the medicine needs growing to injected articles, promote
The development of injection molding technology level and raising, in the figuration manufacture of Modern Mold, due to working of plastics indoor design increasingly
Complexity, injection day by day complicates, and inhales vacuum pumping hardware as a kind of easily manufactured low cost, unfailing performance is high, can effectively keep away
Exempt from flash and be widely used.
At present, the Making mold on market, the especially internal structure of mould, complex structure, and be sealing space mostly,
Common injection cannot thoroughly be filled and easily flash phenomena, and then affects normal production and manufacture efficiency.Because producing
Product shaped inner is the cavity of a closing, is directly molded the requirement to product difficult to realize and flash problem occurs.Therefore set
Count this kind to inhale vacuum exhaust mechanism to realize its purpose.
Utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, provides a kind of suction vacuum exhaust structure, solves
Interiors of products sealing die cavity cannot be filled up completely with, it is to avoid produces the problem of flash.
For solving above-mentioned technical problem, this utility model employs following technical measures：
Vacuum exhaust structure inhaled by a kind of thin-walled, including exhaustor, air vent, exhaustion plate, fixed plate and air extractor；Described
It is embedded with exhaustor and exhaustion plate, described exhaustor and air vent are located at the upper side and lower side therewith of exhaustion plate respectively in fixed plate
Connection, described air extractor is connected with air vent.
This utility model can also be perfect further by following technical measures：
As improving further, described fixed plate lower surface has the fixing groove being adapted with described exhaustion plate；Described solid
The fixing groove being adapted with exhaustor is had in fixed board.
As improving further, described fixed plate upper surface also has the core groove being adapted with product core.
As improving further, described exhaustion plate upper surface has air discharge duct.
As improving further, described exhaustor quantity is several and is evenly distributed between air discharge duct and core groove
And be connected with the two.
As improving further, described exhaustion plate has two seal grooves, be located at outside in air discharge duct respectively.
As improving further, described seal groove is provided with sealing ring.
As improving further, described exhaustion plate has exhaust duct, and described air vent quantity is several, described row
Air flue is connected with air discharge duct and air vent up and down respectively.
Compared with prior art, this utility model has advantages below：
It is the cavity of a closing inside formed product, be directly molded the requirement to product difficult to realize and flash occurs
Problem.Directly extracting the air in die cavity out during air extractor running makes die cavity be internally formed a vacuum.Air extractor closes
Just carry out the injection mo(u)lding of product after closing, be prevented effectively from the problem being difficult to flash leading to because of die cavity air pressure inside.
Brief description
Accompanying drawing 1 is a kind of schematic diagram (no fixed plate) inhaling vacuum exhaust structure of this utility model；
Accompanying drawing 2 is a kind of sectional view inhaling fixed plate in vacuum exhaust structure of this utility model.
Specific embodiment
With specific embodiment, this utility model is described in further detail below in conjunction with the accompanying drawings.
Refer to Fig. 1 to Fig. 2, a kind of suction vacuum exhaust structure, including exhaustor 10, air vent 20, exhaustion plate 30, fix
Plate 40 and air extractor；It is embedded with exhaustor 10 and exhaustion plate 30, described exhaustor 10 and 20 points of air vent in described fixed plate 40
Not Wei Yu the upper side and lower side of exhaustion plate 30 in communication, described air extractor is connected with air vent 20.Can be used for product
Air in die cavity is completely drawn out formation vacuum pressure and in order to material complete filling molding product and is effectively prevented from flash
The appearance of phenomenon.
Refer to Fig. 1, described fixed plate 40 lower surface has the T-shaped fixing groove being adapted with described exhaustion plate 30；Described
The fixing groove that several are adapted is had with exhaustor 10 in fixed plate 40；Described fixed plate 40 upper surface also has and product type
The core groove that core 50 is adapted is used for placing the core of shaped article.The above groove is all used for fixing or place corresponding
Part.
Refer to Fig. 1, described exhaustion plate 30 upper surface has circular air discharge duct 60, above described circular air discharge duct 60
It is uniformly distributed and connects exhaustor 10, the quantity of described exhaustor 10 is several, described exhaustor 10 upper end is with core groove even
Lead to and extend in product core 50, when exhaustor 10 is evacuated, directly the near closed hollow ring in product core is evacuated.Described
Exhaustion plate 30 on have two circular seal grooves, be located at outside in air discharge duct 60 respectively.It is provided with described seal groove
Sealing ring 70.Using such structure, the air of product type in-core is drawn in air discharge duct by exhaustor, simultaneously using close
Gap between exhaustion plate and fixed plate is carried out sealing and ensures that extraneous air does not enter in exhaust structure by seal.
Refer to Fig. 1 to Fig. 2, in described exhaustion plate 30, have an exhaust duct 80, described exhaust duct about 80 respectively with
Air discharge duct 60 is connected with air vent 20.Preferably, it is provided with two air vents 20 to increase capacity and to speed deflation rate.Described
Exhaust ports 20 are connected with air extractor, by air extractor, total are exhausted.
Total work process：Because the air discharge duct on exhaustion plate is connected with air vent, and by interior outside
Sealing ring makes air discharge duct form an airtight space, is close to simultaneously and is communicated with exhaustor above air discharge duct, exhaustor upper end
Inside the die cavity of insertion product core, so when the air extractor running being connected with air vent, air extractor passes through above-mentioned pass
Air in die cavity is directly extracted out and makes die cavity be internally formed a vacuum by system.Air extractor just carries out the note of product after cutting out
Molded, it is prevented effectively from the problem being difficult to flash leading to because of die cavity air pressure inside.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all this
Within the spirit of utility model and principle, any modification, equivalent substitution and improvement done etc., should be included in this utility model
Within the scope of protection.
