[0002] like figure 1 As shown, the side of the automobile air-conditioning duct is provided with a protruding bracket 101, and the top surface of the bracket 101 is provided with a plurality of protrusions 102. Since the direction of the protrusions is perpendicular to the direction of demoulding, it cannot be directly separated from the upper and lower parts of the mold.
If forced demoulding is used, it will cause deformation or breakage of the protrusion, and it will also strain the inner bracket

Embodiment Construction
[0020] The present invention will be further described below in conjunction with accompanying drawing.
[0021] like Figure 1-4 As shown, the demoulding mechanism of the automobile air-conditioning duct injection mold of the present invention includes a slider insert 1 , a slider body 2 , an inclined guide post 3 , a positioning plate 4 and a spring 5 .
[0022] The bottom of the front end of the slider insert 1 is provided with a forming hole for forming the bump 102 of the automobile air-conditioning duct, and the top of the slider insert 1 is provided with a protrusion 1.1.
[0023] The top surface of the protrusion 1.1 is a first inclined surface 1.1.1, and the bottom surface is provided with a second inclined surface 1.1.2. The front end of the first inclined surface 1.1.1 is higher than the rear end, and the protrusion 1.1 The front end is provided with a first side surface 1.1.3, and the rear end is provided with a second side surface 1.1.4, and the inclination angle ...

The invention discloses a demoulding mechanism of an injection mold for an air-conditioning air duct of an automobile. In a mold-closed state, the forming hole of the slider insert (1) is matched with the bump (102) of the air-conditioning air duct of the automobile, and the sliding block There is a distance between the front end of the insert (1) and the air duct of the automobile air conditioner, the protrusion (102) of the slider insert (1) is embedded in the gap (2.1), and the tail of the protrusion (102) The second side (1.1.4) of the end is against the rear side wall of the notch (2.1), and the first side (1.1.3) of the front end of the protrusion (102) is set between the front side wall of the notch (2.1). There is a distance D1, and the bottom surface of the slider insert (1) is attached to the top surface of the positioning plate (4); the demoulding mechanism can form the air duct of the automobile air conditioner, and can be demolded normally without causing an inner concave The protrusions are deformed or broken and will not cause strain on the bracket.
Description
technical field [0001] The invention relates to the technical field of injection molds, in particular to a demoulding mechanism for an injection mold of an automobile air-conditioning duct. Background technique [0002] like figure 1 As shown, the side of the automobile air-conditioning duct is provided with a protruding bracket 101, and the top surface of the bracket 101 is provided with a plurality of protrusions 102. Since the direction of the protrusions is perpendicular to the direction of demoulding, it cannot be directly separated from the upper and lower parts of the mold. If forced demoulding is used, it will cause deformation or breakage of the protrusions, and will also strain the inner bracket. Therefore, there is an urgent need for a demoulding mechanism that can form the automobile air-conditioning air duct, and can be demoulded normally, without causing deformation or breakage of the inner concave table, and without causing strain on the bracket.
