Abstract
The utility model provides an insert structure provided with an ejector pin inside. By aid of the insert structure, the design and manufacture difficulties can be reduced for a larger insert structure, and the cost of a mold is reduced. The insert structure comprises a front mold, a rear mold, a plate A and a plate B, wherein a cavity is formed between the front mold and the rear mold. The insert structure is characterized in that the upper end surface of the insert is propped against the lower end surface of the cavity, the bottom end surface of the insert is supported on the plate B, the insert is located in an insert mounting cavity formed by the rear mold, the bottom of the ejector pin is fixedly mounted in a mounting groove formed by combination of a bearing plate and a panel, an ejector pin through hole is formed in the insert, and the top of the ejector pin penetrates through a linear groove of the plate B and the ejector pin through hole of the insert sequentially and is propped against the lower end surface of the cavity.
Description
Technical field
The utility model relates to the technical field of structures of product mold, is specially the structure that a kind of mold insert inside arranges thimble.
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, but for the larger mould of some mold insert, 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 structure that the utility model provides a kind of mold insert inside that thimble is set, it compares macrostructure for mold insert, can reduce design difficulty, manufacture difficulty, has reduced the cost of mould.
A kind of mold insert inside arranges the structure of thimble, its technical scheme is such: it comprises front mould, rear mold, A plate, B plate, described front mould, it between 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 B plate, described mold insert is positioned at the formed mold insert installation cavity of described rear mold, the bottom of thimble is installed in backing plate, in the mounting groove that panel combination forms, on described mold insert, have thimble through hole, the straight-line groove of described B plate is run through at the top of described thimble successively, after the thimble through hole of mold insert, be mounted on the lower surface of described die cavity.
It is further characterized in that: the bottom side of described mold insert installation cavity is provided with protrusion groove, and the bottom salient position of described mold insert is positioned at described protrusion groove.
Adopt after structure of the present utility model, owing to having thimble through hole on mold insert, the straight-line groove of B plate is run through successively, be mounted on the lower surface of die cavity after the thimble through hole of mold insert in 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 difficulty, manufacture difficulty, reduce the cost of mould.
