Being provided with back-moving spring, be provided with the die joint of band steam vent in described die cavity, described four die cavities are respectively correspondingly arranged in described discharging
The middle part of plate four edges, is equipped with slide block between each die cavity and stripper, described die joint is located at the sky that four slide blocks are formed
In, described impression bolster is provided with two point cast gate.
Further, the minimum diameter of described two point cast gate is 0.4mm.
Further, I-shaped sub-runner, a diameter of 6mm of described I-shaped sub-runner are offered in described die cavity.
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, symmetrical between described stripper and cavity plate is provided with four types
Chamber, described four die cavities are correspondingly provided with four Angle Pin core-pulling mechanisms, and described cavity plate lower end is provided with push rod, and described push rod overlaps
Being provided with back-moving spring, be provided with the die joint of band steam vent in described die cavity, described four die cavities are respectively correspondingly arranged in described discharging
The middle part of plate four edges, is equipped with slide block between each die cavity and stripper, described die joint is located at the sky that four slide blocks are formed
In, by being provided with the die joint of band steam vent in die cavity, so it is easy to the gas in mold cavity is got rid of, also
It is easy to burr and overlap to producing during typing be purged.

Description of reference numerals: cavity plate 1, stripper 2, die cavity 3, two point cast gate 4, Angle Pin core-pulling mechanism 5, push away
Bar 6, back-moving spring 7.
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 shown in Figure 1 to Figure 3, a kind of three-plate type can process plastics inner thread elbow mould, including impression bolster, stripper
2 and cavity plate 1, it is equipped with runner between described cavity plate 1 and stripper 2 and between stripper 2 and impression bolster, described
Symmetrical between stripper 2 and cavity plate 1 being provided with four die cavities 3, described four die cavities 3 are correspondingly provided with four Angle Pin tube bundle extracting machines
Structure 5, described cavity plate 1 lower end is provided with push rod 6, described push rod 6 is arranged with back-moving spring 7, by being provided with in described die cavity 3
With the die joint of steam vent, described four die cavities 3 are respectively correspondingly arranged in the middle part of described stripper 2 four edges, each die cavity 3 with
It is equipped with the slide block coordinating linkage with Angle Pin core-pulling mechanism 5 between stripper 2, is joined with slide block by Angle Pin core-pulling mechanism 5
Close linkage, the demoulding can be made smooth and easy.During use, utilize Angle Pin core-pulling mechanism 5, carry out the effect of loosing core, also utilize push rod 6 and reset
Spring 7 resets, it is simple to the demoulding is smooth and easy, the full non-trimming of product.
The present embodiment uses four die cavities 3, can obtain production cost and production efficiency with automatic demoulding after waiting injection
Certain improvement.When selecting die joint, be in view of the surface quality that can not have influence on plastic when typing, it is simple to mould
Gas in tool die cavity 3 is got rid of, and also allows for burr and overlap to producing during typing and is purged, after undue mould,
Plastic can stay dynamic model side, is thus prone to take out plastic, the optimum position of die joint, should select outside plastic maximum
Shape profile.
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 I-shaped sub-runner cross section of a diameter of 6mm, plastic center side arranges feed entrance point, uses two point cast gate 4, hole irrigation
The diameter of mouth is defined as φ 0.4mm according to plastic thickness.Utilize push rod 6 core-pulling mechanism, carry out the effect of loosing core, when the space of push pedal
When position is inadequate, being directly sleeved on push rod 6 by back-moving spring 7, during die sinking, ejecting mechanism utilizes push rod 6 pushing out product, then borrows
Make ejecting mechanism reset with the back-moving spring 7 being enclosed within push rod 6, then carry out matched moulds next time, injection.
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.
