The top of the movable insert is in a shape matched with the shape of a product, the lower end of the movable insert is provided with an ascending inclined surface, the ascending inclined surface is abutted against a pushing inclined surface on the inner end of the inclined push block, and the pushing inclined surface on the inclined push block can push the movable insert to move upwards through the ascending inclined surface.
After the scheme of the adoption, because the utility model discloses a movable mould board, slider, oblique ejector pad, movable mold insert, locating plate, positioning spring, the first color is moulded plastics and is accomplished the back, during the die sinking, and the guide pillar can drive the slider outwards to remove to one side, and the slider raises through oblique ejector pad drive movable mold insert and gets into the die cavity, and movable mold insert gets into the die cavity as the core that the second color was moulded plastics, just can accomplish the moulding plastics of first color and second color on a pair movable mould, and the mould structure is comparatively simple.
The invention will be further described with reference to the accompanying drawings and specific embodiments.
Drawings
FIG. 1 is a schematic view of a first color injection molding of the present invention;
FIG. 2 is a schematic illustration of a second shot of the present invention;
FIG. 3 is a schematic view of the inclined push block and the movable insert of the present invention;
fig. 4 is a schematic view of the cooperation between the slide block and the positioning plate of the present invention.
Detailed Description
As shown in fig. 1-4, the utility model relates to a two-shot forming structure of bicolor mold, including movable mould board 1, slider 2, oblique ejector pad 3, movable mold insert 4, locating plate 5, positioning spring 6, spring rod 7, slider connecting rod 8, fixed die plate 9, oblique guide pillar 10.
The fixed die plate 9 is abutted with the movable die plate 1, and the upper end of the inclined guide post 10 is fixed on the fixed die plate 9; the slide block 2 is connected in a slide block groove of the movable template 1 in a sliding manner, a guide post hole 21 on the slide block 2 is movably sleeved with an inclined guide post 10 fixed on the fixed template 9, the outer end of an inclined push block 3 is fixedly connected with the slide block 2 through a connecting rod 32, the inner end of the inclined push block 3 can be abutted against the lower end of the movable insert 4, the upper end of the movable insert 4 upwards extends into the cavity, the positioning plate 5 is connected with the outer side of the slide block 2 through a slide block connecting rod 8, the inner end of the spring rod 7 is fixed on the movable template 1, the outer end of the spring rod 7 is movably penetrated on the positioning plate 5, the positioning spring 6 is sleeved on the spring rod 7, two ends of the positioning spring 6 respectively abut against the groove walls of the positioning plate 5 and the slide block groove of the movable template 1, and the effect of preventing the slide block 2 from moving to the cavity is achieved.
The top of the movable insert 4 is in a shape adapted to the shape of the product, the lower end of the movable insert 4 is provided with a rising inclined surface 41, the rising inclined surface 41 abuts against the pushing inclined surface 31 on the inner end of the inclined push block 3, and the pushing inclined surface 31 on the inclined push block 3 can push the movable insert 4 to move upwards through the rising inclined surface 41.
