Problems solved by technology

[0002] In the construction of digital and precision chemical plants, 3D printing is becoming more and more widely used in the production of complex castings. The sand mold of the engine cylinder head casting mold will be produced by 3D printing. The mold has the following problems: 1. It is difficult to manufacture, takes a long time, and the subsequent assembly is also troublesome; 2. Due to the complex structure of the inner cavity of the cylinder head, split assembly will cause relative interference between the mud core and the sand mold when the sand mold is assembled. In turn, the positioning of the sand mold is not accurate

Abstract

The invention discloses a sand mold of an engine cylinder cover casting mold and a manufacturing method of the sand mold of the engine cylinder cover casting mold. The sand mold comprises a sand moldbody. A mud core is arranged in the center of the sand mold body, and the sand mold body and the mud core are obtained in an integral 3D printing mode. Multiple observation windows are formed in the bottom surface of the sand mold body and oppositely communicate with a cavity in the mud core. Sealing mud blocks are connected with the interiors of the observation windows. Reinforcing holes are reserved in the weak position of the interior of the mud core, and reinforcing parts are installed inside the reinforcing holes. The integral printing mode is adopted by the sand mold, and therefore the mud core interference problem and the locating inaccuracy problem can be solved, dispersed sand in the sand mold can be quickly cleaned away, and the strength is high.

Description

technical field [0001] The invention belongs to the technical field of casting of mechanical parts, and in particular relates to a sand mold of an engine cylinder head casting mold and a preparation method thereof. Background technique [0002] In the construction of digital and precision chemical plants, 3D printing is becoming more and more widely used in the production of complex castings. The sand mold of the engine cylinder head casting mold will be produced by 3D printing. The mold has the following problems: 1. It is difficult to manufacture, takes a long time, and the subsequent assembly is also troublesome; 2. Due to the complex structure of the inner cavity of the cylinder head, split assembly will cause relative interference between the mud core and the sand mold when the sand mold is assembled. This will result in inaccurate positioning of the sand mold. Contents of the invention [0003] The present invention is aimed at the deficiency that prior art exists, ...
