Description of reference numerals：Cavity plate 1, stripper 2, die cavity 3, two point cast gate 4, Angle Pin 5.
Specific embodiment
With reference to 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 the mould emptier of plastic three-way mould, including impression bolster,
Stripper 2 and cavity plate 1, are equipped with stream between described cavity plate 1 and stripper 2 and between stripper 2 and impression bolster
Road, symmetrical between described stripper 2 and cavity plate 1 be provided with four die cavities 3, described four die cavities 3 are respectively correspondingly arranged in described
The middle part of stripper 2 four edges, is equipped with slide block 8, between described die cavity 3 and described slide block between each die cavity 3 and stripper 2
It is provided with push rod, described slide block 8 is provided with first inclined-plane consistent with Angle Pin angle of inclination, described push rod with one end of ejector pin contact
It is provided with the second inclined-plane being connected with the first inclined-plane with one end of shoe contact, by four die cavities and four Angle Pin core pullings
Mechanism 5 uses cooperatively, and slide block 8 and the mate-assist of push rod, makes regrinding-material and plastic safety and nondestructive from mould bad
Ground is released, so can guarantee that plastic not on the basis of deformed damaged and impact outward appearance because of ejection it is ensured that the demoulding is smooth, this time should
With Angle Pin sliding block core-pulling mechanism 5, its motion accurately understands, reliable, no stuck and interference, and mechanism has enough in itself
Rigidity, intensity and wearability, injection can obtain certain changing with automatic demoulding to production cost and production efficiency after finishing
Kind.
In the present embodiment, described four die cavities 3 are correspondingly provided with four Angle Pin core-pulling mechanisms 5, and described cavity plate 1 lower end sets
There is push rod 6, described push rod 6 is arranged with back-moving spring 7, during use, using Angle Pin sliding block core-pulling mechanism 5, carry out core pulling work
With also being resetted using push rod 6 and back-moving spring 7, it is smooth to be easy to the demoulding, the full non-trimming of product.
In the present embodiment, the minimum diameter of described two point cast gate 4 is 0.4mm, and described runner is circle, runner a diameter of
6mm.Using the cross sub-runner section of a diameter of 6mm, plastic center side arranges feed entrance point, using two point cast gate 4, hole irrigation
The diameter of mouth is defined as φ 0.4mm according to plastic thickness.Using push rod 6 core-pulling mechanism, carry out core pulling effect, when the space of push pedal
When position is inadequate, back-moving spring 7 is directly sleeved on push rod 6, during die sinking, ejecting mechanism utilizes push rod 6 pushing out product, then borrows
So that ejecting mechanism is resetted 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 acts on：Stripping result is stable
Persistently, promote constant flow, improve surface smoothness, reduce equipment attrition it is not necessary to mould is cleaned multiple times, reduction in the numbers of seconds and
Waste material, prevents frosting abrasion and abrades, reduce ejection resistance and polishing scratch.
