[0003] In the field of injection molds, the duct is generally formed by a core-pulling mechanism. However, the existing core-pulling mechanism has a complex structure and cannot be applied to the formation of this duct. Summary of the Invention

[0004] The purpose of the utility model is to provide a forced demolding mechanism for an automobile air-conditioning housing mold.

[0005] To achieve the above purpose, the technical scheme adopted by the utility model is as follows: A forced demolding mechanism for an automobile air-conditioning housing mold includes a first core column. A second core column is arranged above the first core column. The lower end of the second core column is inserted into the upper end of the first core column. A rod sleeve is sleeved outside the second core column. The rod sleeve is linked with the second core column. The lower end of the rod sleeve has an outward-expanded orifice. A forming gap is formed between the orifice and the second core column. A slider is connected to the upper end of the second core column. A pull block is connected above the slider. An inclined groove is arranged at the bottom of the slider. The slider cooperates with the inclined groove of the pull block. The pull block is connected with an oil cylinder assembly for driving its horizontal movement. The pull block is connected with a travel switch assembly. The pull block can drive the slider to slide vertically when sliding horizontally.
