Description
Technical field
This utility model relates to mould of plastics field, particularly to four type cavity moulds of a kind of plastic bushing.
Background technology
Along with popularizing of PP-R (random copolymer of ethylene) pipe fitting, PP-R pipe fitting is used in a large number.Generally, PP-R pipe
Part is all to be carried out injection molding by injection machine and obtain.Along with science and technology development, new material is constantly researched and developed, at original base
Accomplishing renewable on plinth, environmental protection, energy-conservation new material, let us sees hope, to some extent solves manufacturing industry
Because shortage of resources problem, the development of new material, bring the biggest market space and development prospect to mould of plastics.But
On market today, often there is the length of injecting cavity, size in mould of plastics, and unreasonable structure causes plastic injection to be discontented with, or
Damaging mould during the demoulding causes mould of plastics to make unsuccessfully, and mould cracks.
Utility model content
The purpose of this utility model is for the deficiencies in the prior art, four type cavity moulds of a kind of plastic bushing, its tool
Having rational in infrastructure, die space utilization rate is high, and the full non-trimming of pipe box part, without current mark, is greatly improved the feature of yield.
For solving the problems referred to above, this utility model offer techniques below scheme: four type cavity moulds of a kind of plastic bushing, bag
Include impression bolster, stripper and cavity plate, between described cavity plate and stripper and between stripper and impression bolster
Being equipped with runner, described impression bolster is provided with two point cast gate, and between described stripper and cavity plate, symmetry is provided with four
Die cavity and four Angle Pin core-pulling mechanisms, described Angle Pin core-pulling mechanism includes slide block, Angle Pin, wedge block, described slide block with
Stripper connects.
Further, between described die cavity and described slide block, be provided with push rod, one end of described slide block and ejector pin contact be provided with
The first inclined-plane that Angle Pin angle of inclination is consistent, one end of described push rod and shoe contact is provided with and is connected with the first inclined-plane
Second inclined-plane.
Further, the minimum diameter of described two point cast gate is 0.4mm.
Further, described runner is circular, a diameter of 6mm of runner.
Further, the surface of described die cavity is provided with carburized layer, and carburized layer thickness is 1～2mm.
Beneficial effect: this utility model includes impression bolster, stripper and cavity plate, described cavity plate and stripper it
Between and stripper and impression bolster between be equipped with runner, described impression bolster is provided with two point cast gate, described discharging
Symmetrical between plate and cavity plate being provided with four die cavities and four Angle Pin core-pulling mechanisms, described Angle Pin core-pulling mechanism includes sliding
Block, Angle Pin, wedge block, described slide block is connected with stripper, by using two point cast gate, makes injecting cavity length size to fit,
Reasonable in design, by four Angle Pin core-pulling mechanisms and four die cavities with the use of, make die space utilization rate high, pipe
The full non-trimming of external member, without current mark, is greatly improved yield.
Accompanying drawing explanation
Fig. 1 is the top view that this enforcement is novel.
Fig. 2 is the axonometric chart that this enforcement is novel.
Description of reference numerals: cavity plate 1, stripper 2, die cavity 3, two point cast gate 4, Angle Pin 5.
Detailed description of the invention
Below in conjunction with Figure of description and embodiment, specific embodiment of the utility model is described in further detail:
As depicted in figs. 1 and 2, four type cavity moulds of a kind of plastic bushing, including impression bolster, stripper 2 and die cavity
Plate 1, is equipped with runner between described cavity plate 1 and stripper 2 and between stripper 2 and impression bolster, described die cavity is solid
Determine plate and be provided with two point cast gate 4, symmetrical between described stripper 2 and cavity plate 1 be provided with four die cavities 3 and four Angle Pins are taken out
Core mechanism, described Angle Pin core-pulling mechanism includes slide block, Angle Pin 5, wedge block, and described slide block is connected with stripper, by adopting
With two point cast gate 4, making injecting cavity length size to fit, reasonable in design, by four Angle Pin core-pulling mechanisms and four types
Chamber 3 with the use of, make die space utilization rate high, the full non-trimming of pipe box part is without current mark.
In the present embodiment, being provided with push rod between described die cavity 3 and described slide block, described slide block sets with one end of ejector pin contact
Having first inclined-plane consistent with Angle Pin 5 angle of inclination, described push rod is provided with one end of shoe contact and coordinates with the first inclined-plane
The second inclined-plane connected, the present embodiment, when the demoulding, coordinates Angle Pin by the first inclined-plane of slide block with the second inclined-plane of push rod
Core-pulling mechanism, can play the effect of assisted demoulding.
In the present embodiment, the minimum diameter of described two point cast gate 4 is 0.4mm, and described runner is circular, runner a diameter of
6mm.Using the most commonly used circular sub-runner, take the circular sub-runner cross section of a diameter of 6mm, plastic center side arranges charging
Position, uses two point cast gate 4, and the diameter of spot pouring mouth is defined as φ 0.4mm according to plastic thickness.Utilize Angle Pin core-pulling mechanism,
Carrying out the effect of loosing core, it is to utilize the cooperations of guide pillars and bushes to act primarily as guide effect mould.
The surface of described die cavity 3 is provided with carburized layer, and carburized layer thickness is 1～2mm.Carburized layer effect: stripping result is stable
Persistently, promote constant flow, improve surface smoothness, reduce equipment attrition, it is not necessary to mould be cleaned multiple times, reduction in the numbers of seconds and
Waste material, prevents frosting abrasion and scratch, reduces ejection resistance and polishing scratch.
Preparing it addition, this pipe fitting is PP-R material, it can be made to use precise injection molding mode.Certainly, this pipe fitting also may be used
The inserts using propylene and PP-R material or HPb59-1 material is made through precise injection molding technique.
The above, be only preferred embodiment of the present utility model, not make technical scope of the present utility model
Go out any restriction, thus every according to technical spirit of the present utility model, above example is made any trickle amendment, equivalent
Change and modification, all still fall within the range of the technical solution of the utility model.
