Abstract
The invention discloses an automobile gearbox shell alloy pressure casting die. The automobile gearbox shell alloy pressure casting die comprises an upper die body and a lower die body. The upper die body is located at the top of the lower die body. A fixed plate is arranged on one side of the bottom of the die wall of the upper die body. A fixed groove is formed in the die wall of the lower die body. A movable plate is arranged at the bottom of the fixed groove. The bottom of the movable plate is connected with a spring through a connection plate. The spring is located in a placing groove. An installation groove is formed in one side of the top end of the placing groove. According to the automobile gearbox shell alloy pressure casting die, the fixed plate is inserted into the fixed groove, alloy liquid flowing into a gap is reduced effectively, and thus waste of the alloy liquid is reduced. Meanwhile, sequent machining steps and workload of people are reduced, time is saved, the cost is reduced, and the problem that the alloy liquid fixes the upper die body to the lower die body and consequently a product cannot be taken out is prevented. The movable plate is pulled out, the spring pushes the connection plate to eject the fixed plate upwards, so that separation of the upper die body and the lower die body is convenient, separation time is saved, and the work efficiency is improved.
