Description
Technical field
This utility model relates to mould of plastics field, can process plastic pipe sleeve mould particularly to a kind of three-plate type.
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, and a kind of three-plate type can process plastic pipe sleeve mould,
It has rational in infrastructure, and injecting cavity length is moderate, and mould has enough rigidity, the full non-trimming of pipe box part without the feature of current mark,
For solving the problems referred to above, this utility model provides techniques below scheme: a kind of three-plate type can process plastic tube cover die
Tool, including impression bolster, stripper and cavity plate, between described cavity plate and stripper and stripper and impression bolster
Between be equipped with runner, described impression bolster is provided with two point cast gate, symmetrical being provided with between described stripper and cavity plate
Four die cavities and four Angle Pin core-pulling mechanisms, one end of the Angle Pin of described Angle Pin core-pulling mechanism is stretched in die cavity, another
End stretches in the skewed slot of cavity plate.
Further, described Angle Pin core-pulling mechanism includes that slide block, Angle Pin, wedge block, described slide block are connected with stripper.
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
Between plate and cavity plate, symmetry is provided with four die cavities and four Angle Pin core-pulling mechanisms, tiltedly leading of described Angle Pin core-pulling mechanism
One end of post is stretched in die cavity, and the other end stretches in the skewed slot of cavity plate, by using two point cast gate, makes injecting cavity length size
Properly, reasonable in design, the product pipe fitting injected is full, and non-trimming occurs without current mark phenomenon, tiltedly leads additionally by four
Post core-pulling mechanism and four die cavities with the use of, can be with automatic demoulding after making injection, mould has enough rigidity, pipe box
The full non-trimming of part, without current mark, so makes production cost and production efficiency obtain certain improvement.
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, a kind of three-plate type can process plastic pipe sleeve mould, including impression bolster, stripper 2 and
Cavity plate 1, is equipped with runner, described type between described cavity plate 1 and stripper 2 and between stripper 2 and impression bolster
Chamber fixed plate is provided with two point cast gate 4, between described stripper 2 and cavity plate 1 symmetrical be provided with four die cavities 3 and four tiltedly lead
Post core-pulling mechanism, the present embodiment is provided with four die cavities 3, with automatic demoulding, height die life, and can use list after waiting injection
The mode of some charging, it is simple to processing, one end of the Angle Pin 5 of described Angle Pin core-pulling mechanism is stretched in die cavity, and the other end stretches into
In the skewed slot of cavity plate 1, by using two point cast gate 4, make injecting cavity length size to fit, reasonable in design, inject
Product pipe fitting is full, and non-trimming occurs without current mark phenomenon, additionally by four Angle Pin core-pulling mechanisms and the cooperation of four die cavities 3
Use, after making injection, can so make production cost and production efficiency obtain certain improvement with automatic demoulding.
In the present embodiment, described Angle Pin core-pulling mechanism includes slide block, Angle Pin 5, wedge block, described slide block and stripper
2 connect, by the connection of slide block Yu stripper 2, it is simple to disposable by pipe box automatic 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.
