Problems solved by technology

[0002] The normal production method of ordinary motor casings is mold leakage or core-pulling molding, which cannot be used for the production of large motor casings
The cooling fins on the outer surface of the large motor case are criss-crossed. When casting by the above method, the casted motor case cannot be demoulded
At present, when casting large-scale motor casings, the motor casings are divided into pieces and demolded from the hollow center. The process is complicated and time-consuming.

Embodiment Construction

[0027] In order to make the structure and processing technology of the present invention clearer, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0028] A method for casting a motor casing, comprising the following steps:

[0029] Step 1: Make a wooden motor shell copy;

[0030] Step 2: Divide the longitudinal section of the wooden motor shell profiling along the axis into four parts, and put each part of the wooden motor shell profiling into a sand box for sand washing and shaping;

[0031] Step 3: Separate each part of the wooden motor casing from the sand box respectively to form four side sand boxes, and each side sand box has a side sand core matching the shape of the outer wall of the motor casing;

[0032] Step 4: Make a lower sand box that matches the shape of the base of the motor casing;

[0033] Step 5: Make an upper sand box that matches the shape of the top ...

Abstract

The invention provides a casting device and a casting method for a motor casing. A large motor casing is produced by adopting a combination method. A plurality of sand boxes are assembled for pouring,the sand boxes are easy to demold after pouring, and an integral motor casing is formed; the motor casing is accurate in dimension, long and thin grooves of heat-dissipating sheets are easy to make,and the casting method is simple to operate.

Description

technical field [0001] The invention belongs to the technical field of large-scale motor casing processing and manufacturing, and in particular relates to a casting device for a motor casing and a casting method thereof. Background technique [0002] The normal manufacturing method of ordinary motor casings is mold leakage or core-pulling molding, which cannot be used for the production of large motor casings. The cooling fins on the outer surface of the large motor casing are criss-crossed. When casting by the above method, the poured motor casing cannot be demolded. At present, when large-scale motor casings are cast, the motor casings are divided into pieces and demoulded from the hollow center. The process is complicated, time-consuming and labor-intensive. Contents of the invention [0003] In order to solve the defects in the prior art, the object of the present invention is to provide an easy-to-cast large-scale motor casing production casting method. [0004] In ...
