When manufacturing a molded product, there was a problem that the drainage due to surface roughness and water leakage due to voids could not be improved.

In addition, as another prior art, disclosed in Publication No. 10-2007-0006184, the "ceiling type air conditioner drain pan manufacturing mold" is coupled to each other in the vertical direction and foam resin is injected after a previously manufactured waterproof member is inserted therebetween. It includes an upper mold and a lower mold to form a drain pan by forming an insulating member on the outside of the waterproof member, and the foam mold resin inflow extending downward to the lower surface of the upper mold and disposed in close contact with the upper outer surface of the waterproof member Since a prevention jaw is included, a technology has been previously disclosed to prevent the foamed resin from flowing into the water collecting part inside the waterproof member through between the upper surface of the waterproof member and the lower surface of the upper mold, but this is a separate manufacturing line for the waterproof member. In addition, the manufacturing process is diversified due to the insert molding process by inserting a waterproof member into the mold when the drain pan is molded, especially during the molding of the drain pan. The structure was complicated, and the end was followed.
