Abstract
The utility model discloses an oblique teeth demouldign mechanism for a plastic mould, which mainly consists of a rear mould, a rear mould bearing and an ejector rod; the upper part of the rear mouldis a mould cavity with oblique teeth, the rear mould is rotatably installed on a lower template by the rear mould bearing; and the ejector rod passes through the rear mould and then extends into the mould cavity. In the utility model, as the ejector rod pushes and props against a workpiece with oblique teeth, the oblique teeth on the workpiece can drive the rear mould which is taken as the lower mould cavity to rotate; and as the rear mould is installed with the rear mould bearing, the rotation is extremely steady and smooth, and the action is reliable; furthermore, as the oblique teeth demoulding mechanism for the plastic mould comprises only a plurality of parts, including the rear mould, the rear mould bearing, the ejector rod and the like, the structure is extremely simple, and the production cycle is shortened.
Description
Technical field
The utility model relates to a kind of mould of plastics, particularly relates to a kind of mould of plastics helical teeth mould emptier.
Background technology
Development is plastics injection mould faster in the mould for plastics, and its plastic product is also being applied more and more widely in daily life, as each industrial circles such as building, machinery, electronics, instrument, instrument.In plastic products injection moulding,, need to adopt special mould emptier carry out the demoulding owing on some plastic products 10 helical teeth (as shown in Figure 1) being arranged.At present, existing helical teeth mould emptier is all comparatively complicated, influences the service life and the maintenance of injection mold.
The utility model content
The purpose of this utility model is to provide a kind of mould of plastics helical teeth mould emptier of simple in structure, reliable in action.
For achieving the above object, technical solution of the present utility model is:
The utility model is a kind of mould of plastics helical teeth mould emptier, and it is mainly held with push rod and formed by back mould, back mold shaft; Mould top, described back is the mold cavity with helical teeth, and back mould holds rotatable being installed on the lower bolster by the back mold shaft; Described push rod passes the back mould and stretches in the mold cavity.
Have an annular boss on the mould outer wall of described back, described mould bearing has two, is socketed in respectively on the upper and lower step surface of annular boss of back mould outer wall.
Described back mould is made of ring-shaped jacket and pellet, described pellet fixedly is nested with the inner chamber at ring-shaped jacket, offer two through holes that allow push rod pass on pellet, the pitch face of the upper surface of pellet and ring-shaped jacket upper port constitutes the mould lower impressions, and the mould upper impression is arranged on the front mould.
After adopting such scheme, because the utility model has the workpiece of helical teeth by the push rod ejection, the helical teeth on the workpiece can order about the back mould rotation as the mould lower impressions, holds rotation steady, smooth and easy, the reliable in action very of getting up because the back mold shaft is housed on the mould of back; And, the utility model forms very simple of structure, production cycle shortening because only being held with several parts such as push rod by back mould, back mold shaft.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Description of drawings
Fig. 1 is plastic products figure;
Fig. 2 is a cutaway view of the present utility model;
Fig. 3 is that the utility model is deviate from mold cavity figure.
The specific embodiment
As Fig. 2, shown in Figure 3, the utility model is a kind of mould of plastics helical teeth mould emptier, it mainly by the back mould 1, the back mold shaft hold 2 and push rod 3 form.
Described back mould 1 is made of ring-shaped jacket 11 and pellet 12.Described pellet 12 fixedly is nested with the inner chamber at ring-shaped jacket 11, on pellet 12, offer two through holes 121 that allow push rod pass, the pitch face 111 of the upper surface of pellet 12 and ring-shaped jacket 11 upper port constitutes the mould lower impressions, and the mould upper impression is arranged on the front mould 4.
Has an annular boss 12 on mould 1 outer wall of described back.Described mould bearing 2 has two 21,22, is socketed in respectively on the annular boss 12 upper and lower step surfaces of back mould 1 outer wall, and back mould 1 holds 21,22 rotatable being installed on the lower bolster 20 by the back mold shaft; Described push rod 3 has two, and the through hole 121 that passes respectively on the mould 1 of back stretches in the mold cavity.
Operation principle of the present utility model:
Emphasis of the present invention just is: the back mould holds by the back mold shaft and is installed on the lower bolster.
