Problems solved by technology
Due to the limitation of the structure of the conventional salt core pressing device, during the salt core pressing process, the operator can only reach in between the upper and lower dies driven by the salt core hydraulic press, and complete salt feeding, smoothing and salt removal in sequence The three actions of the core, these processes require the operator to put his hands between the upper and lower hydraulic dies, the salt core pressing device is easy to press the operator's hands, there is a great potential safety hazard, which seriously affects the operation The personal safety of the operator; in addition, the operator needs to repeat a single action in the process of making a large number of salt cores, and the spirit also needs to be highly concentrated, and the labor intensity is extremely high.

The invention discloses a salt core pressing device based on an oil press with the function of mold pressing and the function of mold collecting and a salt core pressing mold which is mounted on the oil press. The salt core pressing device comprises a salt feeding module, a flattening module and a core collecting module. The salt feeding module comprises a feeding support which is connected to the oil press. A feeding plate is arranged above the feeding support, a salt-type through hole is formed in the feeding plate, and the feeding plate is connected with a material plate push-and-pull mechanism. A hopper is arranged above the feeding plate. The flattening module comprises a flattening brush, and the flattening brush is arranged on the side wall of the front end of the feeding plate of the salt feeding module. The core collecting module comprises a supporting frame, and the supporting frame is connected to the oil press. The supporting frame is provided with a core collecting shifting fork, and the core collecting shifting fork is connected with a shifting fork control mechanism. The invention further provides a salt core pressing method. By means of the salt core pressing device and method, the personal safety of operators is effectively guaranteed, and the labor intensity of the operators is lowered.
Description
technical field [0001] The present invention relates to a mold, and more specifically relates to a salt core pressing device and method. Background technique [0002] The piston is an important part of the engine. When working, the piston can bear the combustion pressure in the cylinder, and transmit this force to the crankshaft through the piston pin and connecting rod, so as to realize the output of kinetic energy. Among them, the aluminum piston is a common type of piston. In the casting process of aluminum pistons, in order to improve the smoothness and dimensional accuracy of the internal oil chamber of aluminum pistons, it is often necessary to use water-soluble salt cores. Water-soluble salt cores are made of water-soluble salt powder particles with a certain particle size. Salt cores with different cross-sectional shapes are produced by processes such as pressing, turning, sintering and drilling. [0003] In actual operation, the salt core is generally pressed by t...
