Description

Universal combined mold and manufacturing method thereof

The application for this case is to apply for both a utility model patent and an invention patent for the invention on the same day, and the name of the utility model invention is a universal combined mold.

technical field

The invention relates to a universal mold, in particular to a combination mold with common mold cores of a disc-shaped head mold and an elliptical head mold, specifically a universal combined mold and a manufacturing method thereof.

Background technique

Molds are various molds used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping, stretching, etc. to obtain the required products. It is a tool used to shape objects. In the head manufacturing industry, the existing molds are usually single ellipse, dish or cone, etc., which can only form the corresponding head. For the ellipse and dish molds with similar core structure, it is impossible to make them Some of the same casting methods are used to save costs and meet the requirements of rational allocation of resources.

Contents of the invention

The object of the present invention is to solve the problem that oval and dish molds with similar mold core structure cannot adopt part of the same casting method to save cost and meet the requirements of rational allocation of resources, and propose a dish and ellipse mold that can A general-purpose combined mold and a manufacturing method thereof.

Technical scheme of the present invention is:

A general composite mold, which includes a mold core and a discharge ring of an elliptical mold, the discharge ring of the ellipse mold is installed on the edge of the mold core, the long axis of the upper mouth of the ellipse mold is Do, and the mold core (1) is provided with a downward Arc surface, radius R of arc surface satisfies: R=Do×0.9045.

The radius r ₁ of the arc surface where the unloading ring of the elliptical mold of the present invention is located satisfies: r ₁ =Do×0.1727.

A general composite mold, which includes a mold core and a discharge ring of a disc-shaped mold. The mold core is provided with a downward arc surface, and the radius of the arc surface is R. The major axis D of the upper mouth of the mold satisfies: D=R.

The radius r ₂ of the arc surface where the unloading ring of the disc-shaped die of the present invention satisfies: r ₂ =0.1D.

A manufacturing method of the universal composite mold described in claims 1 and 3, characterized in that it comprises the following steps:

(a). Manufacture of the mold core: cast the mold core, the mold core is provided with a downward arc surface, and the radius R of the arc surface satisfies: R=Do×0.9045;

(b). The production of the elliptical mold: cast the discharge ring of the elliptical mold, connect the discharge ring of the elliptical mold with the mold core to form an elliptical mold, the major axis of the upper mouth of the elliptical mold is Do, and the arc of the discharge ring of the elliptical mold is located The radius r ₁ of the surface satisfies: r ₁ =Do×0.1727;

(c). The production of the disc mold: cast the unloading ring of the disc mold, connect the unloading ring of the disc mold with the mold core to form a disc mold, and the long axis D of the upper mouth of the disc mold satisfies: D=R , the radius r ₂ of the arc surface where the unloading ring of the disc mold is located satisfies: r ₂ =0.1D.

Beneficial effects of the present invention:

The universal composite mold of the present invention adopts part of the same casting method to save costs and achieve the effect of rational allocation of resources for elliptical and dish molds with a common mold core structure. As the mold core of the ellipse mold, the mold core is connected with the discharge ring of the ellipse mold to form an ellipse mold, and the mold core is connected with the discharge ring of the disc mold to form a disc mold.

Fig. 2 is a schematic diagram of the structure of the dish-shaped mold of the present invention.

Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

As shown in Figure 1, a kind of universal combination mold, it comprises mold core 1 and the unloading ring 2 of elliptical mold, the unloading ring 2 of elliptical mold is installed on the edge of mold core 1, and the long axis of upper mouth of elliptical mold is Do, The mold core 1 is provided with a downward arc surface, and the radius R of the arc surface satisfies: R=Do×0.9045; the radius r ₁ of the arc surface where the unloading ring 2 of the elliptical mold is located satisfies: r ₁ =Do×0.1727.

A general combination mold, which includes a mold core 1 and a discharge ring 3 of a disc-shaped mold. The mold core 1 is provided with a downward arc surface, and the radius of the arc surface is R. The discharge ring 3 of the disc-shaped mold is installed on the mold core 1 edge, the major axis D of the top of the disc mold satisfies: D=R; the radius r ₂ of the arc surface where the unloading ring 3 of the disc mold is located satisfies: r ₂ =0.1D.

When using it specifically:

In the general combined mould, the mold core 1 of the elliptical mold is used in conjunction with the discharge ring 2 of the elliptical mold as the mold core of the elliptical mold to make an elliptical head. Take an ellipse mold with a diameter of 2 meters as an example: the diameter of the ellipse is 2 meters, that is, the upper major axis Do of the ellipse mold is 2 meters, the core 1 is provided with a downward arc surface, and the radius R of the arc surface satisfies: R=Do×0.9045= 1809; when the mold core 1 of this elliptical mold is used as the mold core for forming a dish-shaped head, R=1809=the major axis D of the upper mouth of the dish-shaped head can be made into a dish-shaped head with a diameter of about 1.8 meters. Cooperate with the discharge ring 3 of the mold core 1 and the dish mold to be pressed into a 1.8-meter dish head.

The parts not involved in the present invention are the same as the prior art or can be realized by adopting the prior art.
