Serrated face in the cavity surface of mould.
Above-mentioned that serrated face structure is arranged in the cavity surface of a cover half, one side facilitates processing, on the other hand may be used
So that serrated face structure can be not only arranged on the cavity surface position for the cover half in die sinking direction for being right against dynamic model, also
It can be arranged parallel on the cavity surface position in the die sinking direction of dynamic model without influencing whether to demould, to further increase
Effective contact area of two kinds of plastics in its soft or hard glue bond area.
As one of the preferred embodiment of dual-color forming mode structure in the utility model, the dual-color forming mould is the rotation of type core
The dual-color forming mould of formula structure.
The sequence being molded using the dual-color forming mould of type core rotary structure are as follows: first molded, then by first
Kind plastic injection carries out first time die sinking (dynamic model retrogressing) after molding, the molding of the first plastics into the type chamber of a cover half
Body stays on dynamic model, dynamic model is then rotated 180 degree by dynamic model swivel plate, and carry out docking molding with secondary cover half, molding
Afterwards by the type chamber of second of plastic injection to secondary cover half, so that second of plastics is combined with the first plastics, after molding
It carries out second to be opened, ejects moulding finished product.
As two of the preferred embodiment of dual-color forming mode structure in the utility model, the dual-color forming mould is de- plate rotation
The dual-color forming mould of formula structure.
The beneficial effects of the utility model are:
First, a kind of dual-color forming mould of the utility model, by the way that concaveconvex structure is arranged in the cavity surface of a cover half,
Contact area of two kinds of plastics in its soft or hard glue bond area can be increased to mention to enhance the bonding strength of bond area
The high quality of moulding.
Second, dotted sunk structure is arranged in a kind of dual-color forming mould of the utility model in the cavity surface of a cover half,
It also helps and facilitates processing.
Serrated face structure is arranged in third, a kind of dual-color forming mould of the utility model in the cavity surface of a cover half,
On the one hand processing is facilitated, on the other hand can make serrated face structure not only can be arranged in the die sinking direction for being right against dynamic model
A cover half cavity surface position on, can also be arranged parallel to dynamic model die sinking direction cavity surface position on without
Demoulding is influenced, to further increase two kinds of plastics in effective contact area of its soft or hard glue bond area.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of dual-color forming mould of the utility model；
Fig. 2 is that the junction of two kinds of plastics is the schematic diagram with dot bulge or pitting；
In figure: 1, dynamic model, 2, cover half, 3, secondary cover half, 4, concaveconvex structure, 5, dynamic model swivel plate, 6, cover half fixes
Plate, 7, the plastics of the first color, 8, the plastics of second color.
Specific embodiment
