AI Technical Summary

Technical Problem

The existing cooling device with local extrusion structure of die-casting mold with cooling function is simple in structure and will not produce direct thermal conduction and cooling effect on the oil cylinder, resulting in excessive temperature of the oil cylinder and sealing ring, losing the sealing effect, causing damage to the extrusion structure and production. Delay.

Method used

A local extrusion structure of die-casting mold with oil cylinder cooling block is designed. The cooling block is in direct contact with the transition coupling, oil cylinder and sealing ring. The upper and lower cooling water paths are set inside, and heat is transmitted through threaded connections, and the water path is sealed through stainless steel balls. Processing holes.

Benefits of technology

It realizes rapid cooling of the oil cylinder and sealing ring, extends the life of the local extrusion structure, and reduces cost waste and production delays caused by damage to the extrusion structure.

Abstract

A die-casting die local extrusion structure with an oil cylinder cooling block comprises a mold core, a guide block, a transition coupler, the cooling block and an oil cylinder. A round hole is formed in the middle of the cooling block; an upper cooling water path, a lower cooling water path and a connecting water path are arranged in the cooling block; the upper cooling water channel is connected with the water inlet, and the lower cooling water channel is connected with the water outlet; a sealing ring is arranged on the oil cylinder; the transition coupling is assembled in the guide block, a threaded section is arranged at the lower end of the transition coupling, and the threaded section penetrates through the circular hole of the cooling block and the sealing ring on the oil cylinder to be in threaded connection with the oil cylinder; a groove is formed in the upper end of the transition coupling; and the mold core penetrates through the guide block and is assembled in the groove. The cooling block connected with the oil cylinder is designed, the double-layer surrounding type cooling water way is designed in the cooling block, the oil cylinder and a sealing ring of the oil cylinder can be efficiently cooled, and the risk that the oil cylinder is damaged is reduced.
