Problems solved by technology

[0002] Usually, the gear box shell of the water wheel aerator is made of aluminum or cast iron, which will rust when used in seawater. If it is replaced by plastic, it will not rust. It cannot be demolded by the usual method. For example, the invention patent disclosed in Patent No. 201010183010.5 is to divide the gearbox shell into two halves, and after die-casting, the shell is covered with a layer of plastic to prevent corrosion; not only the process is complicated, but also there may be leaks at the joint of the two half shells oil risk

Embodiment Construction

[0034] Below in conjunction with accompanying drawing, the present invention will be further described with specific embodiment, see figure 1 -16:

[0035] A method for manufacturing a plastic gearbox shell of a waterwheel aerator mainly includes injection molding equipment and a mould. The mold is mainly composed of a core and no less than two openable and closable cavity blocks 5 . The core is divided into a main core 3 and a secondary core 4 , and the secondary core 4 is arranged on the main core 3 . After the mold is injected with plastic on the injection molding equipment, the mold is opened and the workpiece is separated from the main core 3, and the auxiliary core 4 remains in the workpiece, that is, the auxiliary core 4 remains in the injection-molded plastic gearbox shell 12, and the auxiliary mold Core 4 is taken out from the vacancy left after breaking away from main core 3, and the method for taking out secondary core 4 includes manually taking out or manipulator ...

Abstract

The invention relates to a manufacturing method of a plastic reduction box shell and a plastic reduction box of a waterwheel aerator, mechanical machining processes are reduced, the plastic reductionbox shell and an existing cast iron reduction box shell can be arranged into the same assembling dimension basically, the cost is reduced, and meanwhile, the reduction box shell never rusts.

Description

technical field [0001] The invention belongs to aquaculture equipment, and particularly refers to a manufacturing method of a plastic reduction box shell, a mold, a plastic reduction box of a waterwheel aerator, and a waterwheel type aerator with a plastic reduction box. Background technique [0002] Usually, the gear box shell of the water wheel aerator is made of aluminum or cast iron, which will rust when used in seawater. If it is replaced by plastic, it will not rust. It cannot be demolded by the usual method. For example, the invention patent disclosed in Patent No. 201010183010.5 is to divide the gearbox shell into two halves, and after die-casting, the shell is covered with a layer of plastic to prevent corrosion; not only the process is complicated, but also there may be leaks at the joint of the two half shells oil risk. Contents of the invention [0003] The purpose of the present invention is to provide a manufacturing method of a plastic reduction box shell, ...
