Abstract
The utility model relates to a casting die, in particular to a casting die for a rotor of a motor. The casting die for the rotor of the motor comprises a die-casting upper die and a piston. A middle platform face is arranged between the die-casting upper die and the piston. A downward connecting column is arranged on the middle platform face. A hole for insertion of the connecting column is arranged on the die-casting upper die. An exhaust groove is arranged below the middle platform face. The connecting column is inserted in the hole to connect and has a longitudinal moving range in the hole. By adoption of the structure, the casting die has the advantages of removing aluminum blocks in the exhaust groove easily, ensuring smoothness of the exhaust groove for next casting, and improving quality of products.
Description
Technical field
The utility model relates to casting mould, specifically relates to the rotor casting mould of motor.
Background technology
The rotor of motor is comprised of silicon steel sheet group, sliver, end ring etc., forming sliver, melt aluminium in the hole of molten aluminium filling silicon steel sheet group is end ring at silicon steel sheet group two ends, whole production technology is such: the silicon steel sheet group that stacks is placed in the casting mould of casting machine the molten aluminium compacting of cast; In order to guarantee product quality, the air scavenge that will melt in the aluminium as much as possible in the process of moulding is gone out, just designed air discharge duct at the die casting patrix for this reason, in the prior art, on the piston of the casting machine that the die casting patrix is directly fixed, the phenomenon that rotor of casting will stop up air discharge duct so just occurs, and has the cumbersome shortcoming of aluminium block of removing in the air discharge duct.
Summary of the invention
The purpose of this utility model is exactly for above-mentioned shortcoming, and a kind of rotor casting mould of removing easily aluminium block motor in the air discharge duct is provided.
The technical solution of the utility model is achieved in that the rotor casting mould of motor, it comprises die casting patrix and piston, it is characterized in that: table top in the middle of having installed between die casting patrix and the piston, joint pin down is installed on the middle table top, the hole that interspersed joint pin is arranged on the die casting patrix, below middle table top, be provided with air discharge duct, the joint pin connection that inserts in the hole, described joint pin is in Kong Zhongyou scope of activities longitudinally.
The beneficial effects of the utility model are: the casting mould of this spline structure has to be removed easily aluminium block in the air discharge duct, guarantees to cast the advantage that air discharge duct is unimpeded, improve the quality of products next time.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Wherein, 1, die casting patrix 2, piston 3, middle table top 4, joint pin
5, air discharge duct.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, the rotor casting mould of motor, it comprises die casting patrix 1 and piston 2, it is characterized in that: table top 3 in the middle of having installed between die casting patrix 1 and the piston 2, joint pin 4 down is installed on the middle table top 3, the hole of interspersed joint pin is arranged on the die casting patrix, below middle table top 3, be provided with air discharge duct 5, joint pin 4 connection that inserts in the hole, described joint pin 4 is in Kong Zhongyou scope of activities longitudinally.
Described joint pin Kong Zhongyou longitudinally scope of activities refer to: die casting patrix 1 on joint pin 4 time in the middle of below the table top 3 with contact above the die casting patrix 1; Die casting patrix 1 has a segment distance above the following and die casting patrix 1 of middle table top 3 below joint pin 4 time, that is to say, die casting patrix 1 has movable leeway at joint pin 4; When below the middle table top 3 and die casting patrix 1 above when a segment distance is arranged, the aluminium block in the air discharge ducts 5 below the table top 3 is realized effect of the present utility model in the middle of can removing easily.
