This application has the advantage that can be used for tectorial membrane sand preparation sand mould.

Description

Mould for precoated sand

Technical Field

The application relates to the technical field of bearing seat casting, in particular to a mold for precoated sand.

Background

The bearing seat is a structure for installing and fixing a bearing, in the production process, part of the bearing seat is manufactured by casting, and in the casting process, a waist-shaped hole of the bearing seat is formed by using a sand mold, but the existing clay sand mold cannot meet the production requirement of high precision in the using process. When the precoated sand is used as a sand mold, the existing clay sand mold cannot be used.

SUMMERY OF THE UTILITY MODEL

To the not enough that prior art exists, one of the purpose of this application is to provide a mould for tectorial membrane sand, its advantage that can be used for tectorial membrane sand preparation sand mould.

The above object of the present application is achieved by the following technical solutions:

the utility model provides a mould for tectorial membrane sand, includes mould and lower mould, the lower mould on be equipped with and hold the chamber, last mould on be equipped with the die cavity, last mould on still be equipped with and stretch into to the subregion board that holds the intracavity, the subregion board with the chamber wall that holds the chamber laminate mutually.

Through adopting above-mentioned technical scheme, when using, go up the mould and laminate mutually with the lower mould for the die cavity with hold the chamber and be linked together, and the existence of subregion board makes tectorial membrane sand not contact each other between the shaping back different positions, more convenient to use, tectorial membrane sand is after the shaping, is arranged in the casting, and intensity is high, and the draft angle is little, makes the precision of casting the product higher.

The application may be further configured in a preferred example to: the molding cavity comprises a molding cavity I, a molding cavity II and a communicating cavity, the molding cavity I and the molding cavity II have the same structure, and the molding cavity I and the molding cavity II are communicated through the communicating cavity.

Through adopting above-mentioned technical scheme, in use promptly, a plurality of sand moulds can be made to the single for manufacturing efficiency improves greatly.

The application may be further configured in a preferred example to: the communicating cavity comprises two reinforcing cavities which are respectively communicated with the first molding cavity and the second molding cavity.

Through adopting above-mentioned technical scheme, strengthen the existence in chamber and make the sand mould make the back of accomplishing, the intensity of sand mould is bigger, and is not fragile.

The present application may be further configured in a preferred example to: the communicating cavity also comprises an arc-shaped cavity.

Through adopting above-mentioned technical scheme, the existence in arc chamber makes the sand mould accomplish the back making, and the sand mould intensity of intercommunication chamber department is bigger.

Detailed Description

The present application is described in further detail below with reference to the attached drawings.

Referring to fig. 1-4, for a mould for tectorial membrane sand that this application discloses, including last mould 1 and lower mould 3, be equipped with on the lower mould 3 and hold chamber 31, upward be equipped with die cavity 2 on the mould 1, die cavity 2 includes one shaping chamber 21 and two shaping chambers 22, one shaping chamber 21 is the same with two shaping chamber 22 structures, die cavity 2 still includes intercommunication chamber 23, one shaping chamber 21 and two shaping chamber 22 are located the both sides of intercommunication chamber 23 and all are linked together with intercommunication chamber 23, upward still be equipped with partition plate 11 on the mould 1, partition plate 11 sets up between one shaping chamber 21 and two shaping chambers 22. The communication cavity 23 comprises two reinforcing cavities 25, and the two reinforcing cavities 25 are respectively communicated with the first molding cavity 21 and the second molding cavity 22. The communication cavity 23 further comprises an arc-shaped cavity 24, and the arc-shaped cavity 24 is arranged between the first forming cavity 21 and the second forming cavity 22.

The implementation principle of the embodiment is as follows: when the mold is used, the precoated sand is filled in the accommodating cavity 31 and the mold cavity 2, and the upper mold 1 and the lower mold 3 are attached to each other, so that the precoated sand is molded.

The embodiments of the present invention are preferred embodiments of the present application, and the scope of protection of the present application is not limited by the embodiments, so: equivalent changes in structure, shape and principle of the present application shall be covered by the protection scope of the present application.
