Abstract
The invention provides a core pulling structure of a rotating slide oil cylinder. According to the core pulling structure, a die of a product with an embedded cavity defined by an arc surface most is simple in structure and low in manufacture cost, a die assembly process is simple, and the production efficiency of products is improved. The core pulling structure comprises a front die and a rear die, wherein a cavity is defined between the front die and the rear die, a product is contained in the cavity, and an embedded cavity structure is formed above one side of the product. The core pulling structure is characterized in that the front die and the rear die are provided with installation cavities corresponding to the side provided with the embedded cavity structure; the lower arc surface side of an insert with an arc surface clings to the arc surface of the embedded cavity structure, the inner side of the insert with an arc surface goes deep into the embedded cavity structure, the center of the insert with an arc surface is fastened to the front die through a rotating shaft, the upper outer side of the insert with an arc surface is provided with a convex connecting rod, the upper end surface of the connecting rod clings to the upper end surface of the installation cavity in a die assembly state, and a guide straight slot is formed in the outer end of the connecting rod.
Description
Technical field
The present invention relates to the technical field of structures of product mold, be specially a kind of rotation line position loose core of oil cylinder structure.
Background technology
Existing by the most of product that forms embedded cavity that surrounds of arc surface, it need to form mould by polylith mold insert composite assembly, and need a plurality of sidepiece slide block structures to connect respectively corresponding insert structure, whole mould structure is complicated, the cost of manufacture of mould is high, and mould matched moulds process is complicated, makes the production efficiency of product low.
Summary of the invention
The invention provides a kind of rotation line position loose core of oil cylinder structure, it makes by the mould structure of the product of the embedded cavity of the most of encirclement formation of arc surface simple, and the cost of manufacture of mould is low, and mould matched moulds process is simple, improves the production efficiency of product.
A kind of rotation line position loose core of oil cylinder structure, its technical scheme is such: it comprises front mould, rear mold, described front mould, between rear mold, form die cavity, in described die cavity, it is product, one side top of described product is embedded cavity structure, it is characterized in that: described front mould, rear mold is provided with installation cavity corresponding to described embedded cavity structure side, the arc surface of being close to described embedded cavity structure with the bottom arc surface side of arc surface mold insert, the described inner side with arc surface mold insert is goed deep in described embedded cavity structure, the described center with arc surface mold insert is anchored on described front mould by rotating shaft, the described upper outside with arc surface mold insert is provided with the connecting rod of evagination, the upper surface of described installation cavity is close in the upper surface of the described connecting rod under matched moulds state, the outer end of described connecting rod is provided with guiding straight trough, the roller pin of the hydraulic stem evagination of Vertical Cylinders is installed in described guiding straight trough, it also comprises front mould mold insert, described rear mold is close in the lower end of described front mould mold insert, the outside of described front mould mold insert is fastenedly connected the side hydraulic bar of sidepiece oil cylinder, the interior side-lower of described front mould mold insert is close to the lateral surface of described embedded cavity structure, the lower surface of described connecting rod is close in the inner side, top of described front mould mold insert, the outer upper end face of described front mould mold insert is close in the lower surface of the hydraulic stem of described Vertical Cylinders.
Adopt after structure of the present invention, before the demoulding, the side hydraulic bar action of sidepiece oil cylinder, make front mould mold insert outwards detach installation cavity, the hydraulic stem of Vertical Cylinders moves downwards afterwards, under the downward drive of roller pin, connecting rod drives the inner side with arc surface mold insert to leave embedded cavity structure around rotating shaft, until the demoulding does not interfere, now, front mould, rear mold is separated, front mould drives band arc surface mold insert to depart from die cavity, during matched moulds, only need make successively the hydraulic stem of Vertical Cylinders, the side hydraulic bar action of sidepiece oil cylinder puts in place, it makes by the mould structure of the product of the embedded cavity of the most of encirclement formation of arc surface simple, the cost of manufacture of mould is low, and mould matched moulds process is simple, improve the production efficiency of product.
