Its further technology contents is: described jewellery articles for use die cavity is the tree shaped model chamber, described tree shaped model chamber comprises main running channel and several product die cavities that are communicated with main running channel, and described main running channel is communicated with each product die cavity by the branch running channel of the tiny type that is provided with.
Its further technology contents is: described alignment pin is a straight pin, and the end of described straight pin is provided with outer chamfered section; Described locating hole is a cylindrical hole; The end of described cylindrical hole is provided with interior chamfered section.
Its further technology contents is: described alignment pin is the prismatic pin, and the end of described prismatic pin is provided with outer chamfered section; Described locating hole is the prismatic hole; The end in described prismatic hole is provided with interior chamfered section.
Its further technology contents is: described first template is provided with lock pin, and described second template is provided with and the corresponding lockhole of the lock pin of first template.
Its further technology contents is: described lock pin and lockhole are two, and are located at first template, the symmetrical both sides of second template respectively.
Its further technology contents is: described lock pin is the self-lock pin of band spring.
The utility model beneficial effect compared with prior art is: the utility model adopts acrylic (PMMA) template, and the cured mould that makes shaping breaks away from mould and not fragile easily, has easy processing, cost is low and defect rate is low characteristics; Simultaneously because the transparent effect of template, the cured forming process of notes can be observed outside, operating personnel people can in time understand the cured forming process of notes, between first template and second template, be provided with automatic locking mechanism in addition, make and annotate after first template and the second template matched moulds when cured, need not operating personnel and clip for a long time, reduce labor intensity of operating personnel, and can be applied in the cured equipment of notes of automation.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
