Description
Technical field
The utility model relates to a kind of mould, relates in particular to a kind of mould of tool slide block mechanism.
Background technology
Moulding has side concave-convex constructed products, needs mould to have taper pin formula slide block mechanism and ejector pin mechanism usually.Taper pin formula slide block mechanism generally comprises taper pin and slide block, and wherein slide block cooperates the side concave-convex structure with shaped article with die, and taper pin drives then that slide block is displaced sideways so that the mould die sinking.Thimble structure promotes shaped article and die and breaks away from and shaped article is ejected after die sinking, so that take out shaped article.
Yet in the mould of above-mentioned existing tool slide block mechanism, slide block mechanism and ejector pin mechanism need occupy big die space; Less when small product size, when die space was comparatively nervous, the mould of this structure was difficult to meet the demands; And this mould structure more complicated, make also difficulty.
The utility model content
The purpose of this utility model is to provide a kind of mould that takies die space tool slide block mechanism little, easy to manufacture at the defective that above-mentioned prior art exists.
For achieving the above object, the utility model provides the mould of two kinds of tool slide block mechanisms.
The mould of first kind of tool slide block mechanism is used for the post forming of plastic product, comprises a male model benevolence, a mother module core and a slide block mechanism at least, offers a containing hole on the described male model benevolence; Described slide block mechanism is contained in the containing hole of this die, and slide block mechanism comprises that a sliding part and is fixed in the correcting part that the correcting sliding part moves on the male model benevolence, and a side of this sliding part is provided with fixed structure according to the shape of this plastic product.
The mould of second kind of tool slide block mechanism is used for the post forming of plastic product, comprises a male model benevolence, a mother module core and a slide block mechanism at least, offers a containing hole on the described mother module core; Described slide block mechanism is contained in the containing hole of this die, and slide block mechanism comprises that a sliding part and is fixed in the correcting part that the correcting sliding part moves on the male model benevolence, and a side of this sliding part is provided with fixed structure according to the shape of this plastic product.
The mould of the utility model tool slide block mechanism is after the plastic product is finished moulding, and the plastic product is held in the fixed structure of sliding part.Separate with mother module core in male model benevolence, promptly after the die sinking, drive sliding part by the push rod on the injection machine earlier and move, the plastic product moves with sliding part and breaks away from die, can take out the plastic product thus easily and avoid the damage of plastic product.
As mentioned above, the mould of the utility model tool slide block mechanism has replaced taper pin formula slide block mechanism and ejector pin mechanism in the prior art to be located at slide block mechanism on male model benevolence or the mother module core, designs simplification not only, the convenient manufacturing, and it is little to occupy die space, is applicable to the situation that die space is comparatively nervous.
