Detailed description of the invention
Below in conjunction with accompanying drawing, also by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of shaped piece precise injection mould structure, comprise die shoe 13, center counterdie 7, below mould 6, upper bolster 2 and patrix 3, the present embodiment is described with direction shown in accompanying drawing 1, die shoe upper center is fixed with lower mold assemblies, lower mold assemblies is made up of center counterdie 7 and following mould 6, forms annular die cavity at center counterdie and following mould seam upper end;
Above die shoe, be coaxially mounted opposite upper bolster 2, in the middle part of this upper bolster lower end, be fixed with patrix 3; Be shaped with the injection-tube be connected with raw material implanter at patrix center, die shoe is relative with upper bolster when fastening, and forms injection moulding die cavity between patrix and the composition surface of lower mold assemblies;
Innovative point of the present utility model is:
In order to form the side structure of moulding, difference installation side pushing-type composite module in the upper and lower die holder of injection moulding die cavity arranged on left and right sides, shown in accompanying drawing 1, the side-push composite module of these both sides is designed with different Locating driver modes according to processing request;
The stability of positioning molding module during in order to ensure injection moulding, a location forming module 5 is had in the right side drive installation of injection moulding die cavity, be fixed with the positioning and locking block 4 of a wedge shape end face in upper bolster on the right side of this positioning molding module, the through upper bolster lower end of this positioning and locking block is used for the horizontal guide slot 16 of side-push composite module guiding movement; When upper bolster presses down, this positioning and locking block presses down wedge shape end face extruding positioning molding module and moves to injection moulding die cavity center,
In order to ensure the machining accuracy of complicated shape, in the middle part of the die shoe in the left side of injection moulding die cavity, horizontal cross is fixed with a cylinder 1, and the piston rod end of this cylinder is stretched in upper bolster, is shaped with the horizontal guide slot 16 for piston rod horizontal extension in upper bolster; Piston rod end is provided with one and is directed to pattern block assembly, be directed to pattern block assembly to be made up of upper module 8, lower module 9, set bolt 10 and guiding voussoir 11, be fixedly mounted with the middle part of lower module 9 in piston rod end, lower module upper end is fixed with a upper module by set bolt; Guiding voussoir is all fixed with at the pattern block assembly that is directed to of cylinder link both sides.
Shown in accompanying drawing 3, in the upper bolster of horizontal guide slot both sides, symmetry is fixed with auxiliary latch segment 12, the auxiliary latch segment correspondence guiding voussoir of these both sides, when upper bolster presses down, auxiliary latch segment compresses guiding voussoir, thus the double locking coordinating cylinder to be formed being directed to pattern block assembly is located.
In order to accurate processing request, upper module is shaped with the extension projection 15 stretched in injection moulding die cavity, and this extension projection makes moulding side form upper and lower bilateral fin.
