Hollow body molding aid and molding method

A hollow body molding method, using a hollow body molding aid, wherein

• the hollow body molding aid comprises:
• a body;
• a connector, fixedly connected to the body;
• a first profiling assembly, wherein the first profiling assembly is fixedly disposed on a first side of the body and configured to position a first half of a reinforced housing;
• a second profiling assembly, wherein the second profiling assembly is fixedly disposed on a second side of the body and configured to position a second half of the reinforced housing;
• and
• a positioning mechanism, disposed on the first profiling assembly and the second profiling assembly;
• wherein the body comprises a first support plate, a second support plate, and connecting plates, the first support plate is fixedly connected to the second support plate through the connecting plates, the first support plate, the second support plate, and the connecting plates form an accommodation space, the first profiling assembly is disposed on the first support plate, the second profiling assembly is disposed on the second support plate, and a plurality of through holes are equally formed on each of the connecting plates;
• the method comprising the following steps:
• fixing the first half of the reinforced housing to the first profiling assembly;
• fixing the second half of the reinforced housing to the second profiling assembly;
• controlling a manipulator to drive the hollow body molding aid to feed the reinforced housing into a cavity of a mold;
• performing blanking on a molten cylindrical blank;
• sealing an open side of the molten cylindrical blank;
• pre-blowing the molten cylindrical blank to pre-inflate the molten cylindrical blank;
• controlling the mold to close;
• blowing the molten cylindrical blank at high pressure, wherein the molten cylindrical blank is adhered to the reinforced housing and forms an integral part of the reinforced housing;
• cooling the molten cylindrical blank for shaping;
• and
• controlling the mold to open to take out a molded hollow body.
