Description
Technical field
The present invention relates to technical field of mold, specifically a kind of back-off loose-core injection mould.
Background technique
Injection mold is a kind of tool for producing plasthetics;Also plasthetics complete structure and accurate dimension are to confer to
Tool.Injection molding is a kind of processing method used when producing certain complex-shaped components in batches, refers specifically to melt heated
Plastics by injection molding machine high pressure inject die cavity obtain formed products after cooling and solidifying.
In Injection Mold Design, the position interferenceed with die sinking direction occurred in product is known as being buckled to.Such as fruit product
As a result it is buckled to, is that can not go to design with common stripping means.Therefore, corresponding back-off is had do such mold design
Processing system.Currently used back-off processing method is fixed mold push plate with dynamic, and implementation includes that deduction is realized, spring is realized
Deng.And these mode motion processes have the de- wound of different degrees of back-off to product, product production qualification rate is low, and cost is got higher.
Summary of the invention
The purpose of the present invention is to provide a kind of back-off loose-core injection moulds, have down to solve the mold of traditional back-off structure
Button takes off wound and product produces the low problem of qualification rate.
To achieve the above object, the invention provides the following technical scheme:
A kind of back-off loose-core injection mould, including preceding membrane module and rear membrane module, the preceding membrane module include preceding mould A plate and preceding mould
Panel, is equipped with front cavity and take-up housing in the preceding mould A plate, it is described after membrane module include rear mold B plate, rear mold thermal insulation board and after
Baffle plate, the rear mold thermal insulation board and rear baffle plate are screwed.The rear mold B intralamellar part be equipped with molding after with sliding block
The shovel base that matches of seat, the preceding mould A intralamellar part be provided with front cavity and matched with front cavity cavity surface pin A, activity
Inserts and pin B, pin A are connected with pin B by removable insert, are provided with oil cylinder on the outside of the preceding mould A plate, oil cylinder
The flat bit architecture of piston rod is connect by take-up housing with pin B, the rear cavity and front cavity type is intracavitary is equipped in through-plane structure
Injecting products, at a distance of 0.5mm between the cylinder piston rod and take-up housing interface.
Based on the above technical solution, the present invention also provides following optional technical solutions:
In a kind of optinal plan: the take-up housing of shovel base and rear membrane module in the preceding membrane module is cooperated by inclined-plane.
In a kind of optinal plan: Ejector Retainer Plate and thimble panel are installed between the rear mold thermal insulation board and rear mold B plate,
The two sides of thimble panel are fixed with square iron.
In a kind of optinal plan: being equipped with thimble, support column on the thimble panel and around answering on the support columns
Position bar spring.
In a kind of optinal plan: being also equipped with guide sleeve and guide post on the rear mold B plate, be equipped on the preceding mould A plate
Sprue bushing, the center position of the preceding die face plate are fixed with positioning ring, mould thermal insulation board before being additionally provided on the preceding mould A plate.
Compared to the prior art, beneficial effects of the present invention are as follows:
1, the invention avoids the de- wound of back-off, side slipper block loose core, side entirety mold insert form are used, and product structure is tight
It gathers, interior mold insert activity space is very limited, can only be by rotatably deviating from；
2, it after product of the present invention is taken out with interior mold insert, is placed in specific tooling, takes out mold insert rapidly, convenient and efficient, mould structure
Novel design, product stripping will not be pulled, and qualification rate is high, and it is difficult that effective solution is opened the product of compact back-off structure

Specific embodiment
Following embodiment can be described in detail the present invention in conjunction with attached drawing, in attached drawing or explanation, similar or identical part
Using identical label, and in practical applications, shape, thickness or the height of each component can be expanded or shunk.Institute of the present invention
Each embodiment enumerated is only to illustrate the present invention, is not used to limit the scope of the present invention.It is made for the present invention any aobvious
And modification easy to know or change are without departure from spirit and scope of the invention.
Embodiment 1
Please refer to Fig. 1~6, in the embodiment of the present invention, a kind of back-off loose-core injection mould, including preceding membrane module and rear membrane module,
The preceding membrane module includes preceding mould A plate 9 and preceding die face plate 10, is equipped with front cavity 19 and take-up housing 16 in the preceding mould A plate 9,
Membrane module includes rear mold B plate 8, rear mold thermal insulation board 1 and rear baffle plate 4 after described, and the rear mold thermal insulation board 1 and rear baffle plate 4 are logical
It crosses screw to fix, the shovel base 17 matched after molding with take-up housing 16, the preceding mould A plate 9 is installed inside the rear mold B plate 8
It is internally provided with front cavity 19 and the pin A21 matched with 19 cavity surface of front cavity, removable insert 22 and pin B23, pin
A21 is connected with pin B23 by removable insert 22, and the outside of the preceding mould A plate 9 is provided with oil cylinder 15,15 piston rod of oil cylinder
Flat bit architecture is connect by take-up housing (16) with pin B23, the rear cavity 18 and 19 type of front cavity is intracavitary is equipped in through-plane
The injecting products of structure, the pin A21 are held in the mouth through side wall insertion injecting products inside, the cylinder piston rod 15 with take-up housing 16
At a distance of 0.5mm between junction；
The take-up housing 16 of shovel base 17 and rear membrane module in preceding membrane module is cooperated by inclined-plane；
Before molding, by pin A21, removable insert 22, tri- entirety of pin B23 are assemblied on take-up housing, then oil cylinder oil cylinder
15 are first advanced at greatest limit position, and there are also the gaps 0.5mm for cavity surface of the pin A21 apart from front cavity 19, because product should
Structure is through-plane, so must be closed completely, therefore mold needs to carry out second movement, preceding membrane module and caudacoria group
Part clamping process, the take-up housing 16 of shovel base 17 and rear membrane module in preceding membrane module make take-up housing after molding by inclined-plane cooperation
16 continue the 0.5mm that marches forward, so that pin is bonded completely in 19 cavity surface of front cavity；After die sinking, oil cylinder carries out backward movement,
Take-up housing 16 and mold insert B23 and removable insert 22 is driven to shrink back together；Can making mold insert B23 in this way, first the core pulling from product goes out
Come；In knockout course: mold insert A21 first starts die face plate 10mm before retreating, and discovery has interference with product medial surface, can not be successfully de-
Mould, it is therefore desirable to first rotate mold insert A21 to certain angle, it then just can be with used right edge, using injecting products from side opening
Apply a thrust, deviates from injecting products completely.
