In the figure: 1. a bottom die; 2. a side mold; 3. a top mold; 4. a core mold; 5. a thimble section; 6. a feed runner; 7. a head; 8. a cylindrical portion; 9. and a main runner.
Description of the embodiments
The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model; it is apparent that the described embodiments are only some, but not all, embodiments of the present utility model, and that all other embodiments obtained by persons of ordinary skill in the art without making inventive efforts are within the scope of this utility model.
Referring to the drawings, in the embodiment, a casting mold for a motor housing includes a bottom mold 1, a side mold 2, a top mold 3, and a core mold 4, wherein the bottom mold 1, the side mold 2, the top mold 3, and the core mold 4 form a die casting chamber, the die casting chamber includes a molding chamber and a return chamber, and the molding chamber is divided into a head portion 7 and a cylindrical portion 8.
Wherein, glue inlet and gas vent set up in cylinder 8 keep away from head 7 one end.
During die casting, sizing material gets into the shaping cavity from the inlet, and the gas in the shaping cavity leaves from the gas vent, and the protruding and motor housing cylinder portion 8 week wall terminal coincidence after the shaping separation, motor housing is more pleasing to the eye, has optimized the runner design simultaneously, and the exhaust effect is good, and motor housing after the electrophoresis can not bubble.
The following optimizations or further description can be made on the basis of the above embodiments, respectively.
Further, the feed back cavity comprises a main runner 9, the main runner 9 is communicated with the glue inlet, and after die casting forming, the main runner 9 section can be clamped, so that the motor shell can be taken out conveniently.
Still further, the feed back cavity includes feeding runner 6, sprue 9 passes through feeding runner 6 with advance the glue mouth intercommunication, feeding runner 6 with advance to be equipped with the breach between the glue mouth, the breach makes feeding runner 6 and advance the glue mouth and be intermittent connection, and feeding runner 6 sections and motor housing cylinder 8 frangible connection after the shaping.
In addition, the feed back cavity includes thimble section 5, thimble section 5 is cylindrically, and thimble section 5 provides the stress point for the ejecting motor housing of thimble, makes things convenient for taking out of motor housing.
Further, the feed back cavity comprises an exhaust runner, the exhaust runner is communicated with the exhaust port, the exhaust runner is wavy, and the wavy exhaust runner enables gas entering the exhaust runner to flow back to the forming cavity after moving up and down, so that the difficulty of gas backflow is improved, and the exhaust effect is improved.
The foregoing is a preferred embodiment of the present utility model, and it should be noted that the scope of the present utility model is not limited thereto. It will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the scope and spirit of the utility model as defined in the appended claims.
