Specific embodiment
Fig. 1-4 show related description figure of the present invention；Specific embodiment is, as shown in Figure 1, Figure 2, Figure 3, Figure 4, one
Mould pitched roof mechanism injection mold before kind is simple, including preceding mould liftout plate 1, top plate spring 2, screw 3, angle ejector rod 4, release link 5, top
Plate movement slots 6, panel 7, stripper plate 8, solid plate 9, moving template 10, support block 11, cover board 12, push plate 13, bottom plate 14.
In the mold, simple preceding mould pitched roof mechanism component includes preceding mould liftout plate 1, top plate spring 2, screw 3, angle ejector rod
4, release link 5, movement of roof slot 6；Angle ejector rod 4 is equipped with by the fastening of screw 3 on preceding mould liftout plate 1, angle ejector rod 4 is used for plastic
The molding and demoulding of preceding model cavity wall side opening, the spring hole slot that mould liftout plate 1 and solid plate are opened up before top plate spring 2 is installed on
It is interior, it is ejected for mould liftout plate 1, angle ejector rod 4 before pushing, the motion guide of the sub-assembly of preceding mould liftout plate 1 and angle ejector rod 4 is by oblique
Mandril 4 is oriented to the inclined hole in the solid plate installed；Release link 5 is installed on type core mold insert, when die closing for will before
Reply position in the top of mould liftout plate 1；Movement of roof slot 6 opens up in template, installation and sideways motion guiding for mechanism.
The mould structure include panel 7, stripper plate 8, solid plate 9, moving template 10, support block 11, cover board 12, push plate 13,
Bottom plate 14；Mold die carrier structure is three template die pin-point gate structures, and panel 7, stripper plate 8, solid plate 9 constitute the cover half portion of mold
Point, moving template 10, support block 11, cover board 12, push plate 13, bottom plate 14 constitute mold dynamic model part.
In the simple preceding mould pitched roof mechanism, the side of preceding mould liftout plate 1 is greater than with the side distance a of movement of roof slot 6
