Abstract

The utility model discloses a round ceramic core injection mould which comprises a fixed mould and a movable mould, wherein four accurate opening and closing devices are mounted on a fixed mould plate of the fixed mould; the lower ends of the accurate opening and closing devices are inserted into a movable mould plate of the movable mould; the movable mould and the fixed mould are opened and closed through the four accurate opening and closing devices; the movable mould and the fixed mould are correspondingly occluded to form two ceramic core forming cavities; the two ceramic core forming cavities are symmetrically distributed along the axial line of the fixed mould plate; ceramic core mould push-pull oil cylinders are mounted on the two sides of the fixed mould plate and arranged on the horizontal axial line of the fixed mould plate; a hollow ejection pin is arranged at the lower parts of the ceramic core forming cavities; a solid ejection pin is also inserted into the hollow ejection pin. Therefore, the product quality can be effectively improved, the finished product rate can be effectively increased, and the solidification deformation of ceramic cores can be avoided.

Description

A kind of round ceramic core injects mould

Technical field

The utility model relates to and is injected into pattern, particularly relates to a kind of round ceramic core and injects mould.

Background technology

Ceramic core general application in modern manufacturing industry is more extensive, such as water valve, chemical liquids valve, prevents in some industries such as static, wherein applies the water economizer of maximum water valves.Its original manufacturing process of ceramic core is blank compacting and two processing steps of sintering, but sintering tends to make ceramic core distortion, and temperature has been crossed distortion, and it is shaky that temperature is low, do not reach requirement of strength, occurs the quality problems such as cracked in twist process.

Summary of the invention

The technical problem that the utility model mainly solves is to provide a kind of round ceramic core and injects mould, can effectively improve quality and the yield rate of product, avoids the curing deformation of ceramic core.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of round ceramic core to inject mould, this round ceramic core injects mould and comprises fixed half and moving half, four accurate shutters are installed on the solid plate of described cover half, precisely the lower end of shutter is inserted in the moving platen of dynamic model, and fixed half and moving half carries out open and close movement by four accurate shutters; After the interlock corresponding to cover half of described dynamic model, form two ceramic core moulding shape chambeies, two ceramic core moulding shape chambeies are along solid plate transversal line symmetry arrangement, ceramic core push cylinder is equipped with in solid plate both sides, pottery core push cylinder is positioned on the transversal line of solid plate, the bottom in ceramic core moulding shape chamber is provided with the pusher thimble of a hollow, is also inserted with a solid thimble in the pusher thimble of hollow.

The beneficial effects of the utility model are: a kind of round ceramic core of the utility model injects mould, can effectively improve quality and the yield rate of product, avoids the curing deformation of ceramic core.

Accompanying drawing explanation

Fig. 1 is that a kind of round ceramic core of the utility model injects the structural representation of a preferred embodiment of mould;

Fig. 2 is the top view that a kind of round ceramic core of the utility model injects mould.

The specific embodiment

Below in conjunction with accompanying drawing, to the utility model, preferred embodiment is described in detail, thereby so that the advantage of utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.

Refer to Fig. 1 and Fig. 2, the utility model embodiment comprises:

A kind of round ceramic core injects mould, this round ceramic core injects mould and comprises cover half 1 and dynamic model 2, four accurate shutters 6 are installed on the solid plate 3 of described cover half 1, and precisely the lower end of shutter 6 is inserted in the moving platen 4 of dynamic model 2, and cover half 1 and dynamic model 2 carry out open and close movement by four accurate shutters 6; After the interlock corresponding to cover half 1 of described dynamic model 2, form two ceramic core moulding shape chambeies 5, two ceramic core moulding shape chambeies 5 are along solid plate 3 transversal line symmetry arrangement, ceramic core push cylinder 7 is equipped with in solid plate 3 both sides, pottery core push cylinder 7 is positioned on the transversal line of solid plate 3, the bottom in ceramic core moulding shape chamber 5 is provided with the pusher thimble 8 of a hollow, is also inserted with a solid thimble 9 in the pusher thimble 8 of hollow.

A kind of round ceramic core of the utility model injects mould and first ceramic core push cylinder 7 is promoted to closed inner mould core in use, again the ceramic powder being pre-mixed and liquid chemical solidifying substance are injected to ceramic core forming cavity 5 fast by two accents, injection mould with preheat function itself accelerates the curing rate of liquid chemical solidifying substance, liquid parts volatilization after solidifying, stays and solidifies complete round ceramic core.

A kind of round ceramic core of the utility model injects mould, can effectively improve quality and the yield rate of product, avoids the curing deformation of ceramic core.

The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model description and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
