Alternatively, the stripper seat 121 is disposed on an upper inner wall of the lower mold body 120, and the first end cap molding cavity 400 and the second end cap molding cavity 700 are defined by the upper side wall of the stripper seat 121 and the lower side wall of the upper mold body 110. In this way, the upper side wall of the demolding seat 121 is matched with the lower side wall of the upper mold body 110 to define a first end cover forming cavity 400 and a second end cover forming cavity 700, after casting molding, the upper mold body 110 is opened, and the demolding seat 121 is operated to move upwards, so that the air conditioner end cover molded on the upper side wall of the demolding seat 121 is smoothly demolded.

Specifically, the upper and lower swing joint between the upper side inner wall of drawing of patterns seat 121 and lower mould body 120, set up base 130 in the below of lower mould body 120, be connected through the support column between base 130 and drawing of patterns seat 121, set up spring 131 between base 130 and lower mould body 120, and the periphery of support column is located to spring 131 cover. Thus, after casting, the upper mold body 110 is opened to expose the demolding seat 121 arranged on the inner wall of the upper side of the lower mold body 120, the demolding seat 121 is jacked up by the support column through pressing the base 130, the air conditioner end cover on the upper side wall of the demolding seat 121 is immediately demolded to complete demolding, the base 130 is reset under the action of the spring 131 after demolding, the demolding seat 121 is embedded into the inner wall of the upper side of the lower mold body 120 again, and the upper mold body 110 is covered on the lower mold body 120 again for secondary casting.
