Abstract

The utility model discloses a self-locking structure of a mould core box. The self-locking structure comprises a bottom plate, wherein the bottom plate is provided with left and right core boxes which are provided with stroke cylinders and are combined to form a whole body; inclined angles of 45 degrees are formed in the four corners of the combined body and are correspondingly provided with matched wedge blocks; the left and right core boxes are provided with a sand injection plate; the wedge blocks are fixedly mounted on the sand injection plate; the sand injection plate is connected with the vertical stroke cylinders; and the sand injection plate and the left and right core boxes are the same in size and are in close fit. The self-locking structure disclosed by the utility model is simple in design, short in manufacturing period, low in mould manufacturing cost and easy to implement; and the labor intensity of workers is reduced and the productivity is improved.

Description

Mould core box self-locking structure

Technical field

The utility model relates to mould applications, and concrete is a kind of mould core box self-locking structure.

Background technology

Cylinder blank the structural design of mould, is made and to be seemed particularly important in process of production, and the core shooter core box divides the selection of core face to be directly connected to the quality of cylinder block casting and the productivity ratio of foundry goods.

We have selected four die sinking core shooters of vertical minute core to make the cylinder body water jacket core, find in process of production: jacket core divides the core face " race sand " phenomenon to occur in process of production, we think that there is defective in the core box structure by analysis, and these problems can cause following problem:

1, operating personnel's " fash " that will often clear up branch box face causes production efficiency not high;

2, the core change in size is big, and precision does not reach technological requirement;

3, labor strength is big;

4, production environment is seriously polluted.

The utility model content

The utility model provides a kind of dimensional accuracy that can improve core, reduces the mould core box self-locking structure of atmosphere pollution.

The technical solution of the utility model:

Mould core box self-locking structure, comprise base plate, it is characterized in that: described base plate is provided with left and right core box, stroke cylinder all is installed on the left and right core box, and described left and right core box is combined into one, and all to have number of degrees be 45 ° oblique angle at four turnings of this assembly, the corresponding piece of carving that cooperation is installed on the oblique angle, left and right core box is provided with penetrates the sand plate, and the described piece of carving all is fixedly installed in and penetrates on the sand plate, penetrates to connect the perpendicular stroke cylinder of putting on the sand plate.

Described mould core box self-locking structure is characterized in that: described penetrate between sand plate and the left and right core box measure-alike and fit tightly.

Advantage of the present utility model:

After the utility model increased the self-locking structure of core box, what need not change core shooter penetrated sand pressure, can avoid the generation of above defective, improves the dimensional accuracy of core, reduces atmosphere pollution.

The present invention has the following advantages:

1, project organization is simple, and fabrication cycle is short;

2, at the bottom of the die manufacturing cost, be easy to realize;

3, reduce personnel labor, boost productivity.

Description of drawings

Fig. 1 is structural representation of the present utility model.

Fig. 2 is the structure chart of the left and right core box of the utility model.

The specific embodiment

Referring to accompanying drawing, mould core box self-locking structure, comprise base plate 1, base plate 1 is provided with left and right core box, on the left and

right core box

2,3 stroke cylinder 4,5 is installed all, left and

right core box

2,3 is combined into one, and it is 45 ° oblique angle that four turnings of this assembly all have number of degrees, on the oblique angle corresponding cooperation is installed carve piece 6, left and

right core box

2,3 is provided with penetrates sand plate 7, carve piece 6 and all be fixedly installed in and penetrate on the sand plate 7, penetrate to connect on the sand plate 7 and perpendicularly put stroke cylinder 8, penetrate between sand plate 7 and the left and

right core box

2,3 measure-alike and fit tightly.

Claims

1. mould core box self-locking structure, comprise base plate, it is characterized in that: described base plate is provided with left and right core box, stroke cylinder all is installed on the left and right core box, and described left and right core box is combined into one, and all to have number of degrees be 45 ° oblique angle at four turnings of this assembly, the corresponding piece of carving that cooperation is installed on the oblique angle, left and right core box is provided with penetrates the sand plate, and the described piece of carving all is fixedly installed in and penetrates on the sand plate, penetrates to connect the perpendicular stroke cylinder of putting on the sand plate.
