Abstract
The utility model provides a structure for finishing demolding by ejecting inserts by ejector pins. By means of the structure, as for insert structures whose surfaces almost occupy the lower surfaces of cavities, the mold design difficulty can be reduced, the manufacture difficulty is reduced, and the mold cost is reduced. The structure comprises a front mold, a rear mold, a plate A and a plate B, and cavities are formed between the front mold and the rear mold. The structure is characterized in that the upper end surfaces of the inserts are ejected on the lower end surfaces of the cavities, and the bottom end surfaces of the inserts are supported on the rear mold; and the bottoms of the ejector pins are fixedly mounted in a mounting groove formed by the cushion plate and the panel, and the tops of the ejector pins penetrate through the plate B and the rear mold and then are ejected on the lower end surfaces of the inserts.
Description
Technical field
The utility model relates to the technical field of structures of product mold, is specially a kind of thimble and withstands mold insert and complete demolding structure.
Background technology
The structure of existing mould, it all need to be at the outside additional designs thimble structure of mold insert, when guaranteeing again mold insert integrality, guarantee that product can complete the demoulding smoothly, for the surface of mold insert, almost occupy the structure of die cavity lower surface, existing mold is found suitable thimble location comparison difficulty at its periphery again, and it can strengthen design difficulty, increase manufacture difficulty simultaneously, increased the cost of mould.
Summary of the invention
The utility model provides a kind of thimble to withstand mold insert and has completed demolding structure, its for surface almost occupy the structure of die cavity lower surface, can reduce Design of Dies difficulty, manufacture difficulty, reduced the cost of mould.
A kind of thimble withstands mold insert and completes demolding structure, its technical scheme is such: it comprises front mould, rear mold, A plate, B plate, it between described front mould, rear mold, is die cavity, it is characterized in that: the upper surface of mold insert is mounted on the lower surface of described die cavity, the bottom face of described mold insert is supported on described rear mold, the bottom of thimble is installed in the mounting groove that backing plate, panel combination form, and the lower surface that is mounted on described mold insert after described B plate, rear mold is run through at the top of described thimble successively.
Adopt after structure of the present utility model, the lower surface that is mounted on mold insert after B plate, rear mold is run through at the top of thimble successively, mold insert is used as the top of thimble, it makes to offer thimble installing hole without find suitable position in rear mold, it compares macrostructure for mold insert, can reduce Design of Dies difficulty, manufacture difficulty, reduce the cost of mould.
Accompanying drawing explanation
Fig. 1 is front view structural representation of the present utility model.
The specific embodiment
See Fig. 1, it comprises front mould 1, rear mold 2, A plate 3, B plate 4, between front mould 1, rear mold 2, it is die cavity 5, the upper surface of mold insert 6 is mounted on the lower surface of die cavity 5, the bottom face of mold insert 6 is supported on rear mold 2, the bottom of thimble 7 is installed in the mounting groove that backing plate 8, panel 9 be combined to form, and the lower surface that is mounted on mold insert 6 after B plate 4, rear mold 2 is run through at the top of thimble 7 successively.
