Detailed description of the invention
In order to solve the defect of the easy buckling deformation of flat board moulding of middle with hole, the design provides a kind of assembling die,
First goods are carried out injection mo(u)lding, then uses process for stamping to prepare final finished, as it is shown in figure 1, the one provided for the design
The structural representation of assembling die, including die ontology, described die ontology is provided with injection portion and pressing part, described injection portion
Realizing the injection mo(u)lding to goods, described pressing part carries out punching press to goods, thus obtains final finished.
Described die ontology is followed successively by fixed base 1, support column 10 and impression bolster 2 from the bottom to top, and die cavity is fixed
The right side of plate 2 is provided with injection die cavity, left side is provided with punching press die cavity, say, that be provided with injection portion, a left side on the right side of impression bolster 2
Side is provided with pressing part, and described injection portion includes core plate 3, solid plate 4, sprue bush 50 and sprue bush fixed plate 5, described type
Central layer 3 matches with injection die cavity, constitutes the outer surface of injection moulded products, by drawing between described core plate 3 and solid plate 4
Bar 40 is connected, and one end of pull bar 40 is fixed in solid plate 4, and the other end is provided with step, and described pull bar 40 is provided with pull bar bullet
Spring 41, under matched moulds state, pull-rod spring 41 is in compressive state, it is simple to typing, is communicated with injection molding in described sprue bush 50
The running channel in chamber, sprue bush 50 is fixed by screws in sprue bush fixed plate 5, and solid plate 4 is fixed on sprue bush fixed plate 5 times
End；With injection portion homonymy, and between fixed base 1 and impression bolster 2, it is additionally provided with push pedal 22, injection die cavity and push pedal 22
Between be connected by ejector beam 23, the quantity of described ejector beam 23 can be according to the setting of the size reasonable of goods, such as the design
The quantity of middle ejector beam is two, is additionally provided with the guide pillar 100 and guide pin bushing 110 playing the guiding role between injection portion and die ontology,
In the portion of injection simultaneously, there are two die joints, are to be the first die joint between core plate 3 and solid plate 4 respectively, core plate 3 and type
It it is the second die joint between chamber fixed plate 2；Described stamping die intracavity is provided with die 20, and described die 20 top is provided with and is secured to
