The structure comprises a front mold, a rear mold, an A plate, a B plate and a rear mold insert, wherein the front mold, the rear mold, the B plate and the rear mold insert are combined to form a cavity; the product is arranged in the cavity; and the central reversing buckle structure is arranged on the inner side ring surface of the product. The structure is characterized in that the rear mold insert comprises an external ring surface insert and a central insert; the B plate is supported with a push plate; the lower end face of the cavity is clung to the upper end part of a push block; the push block is supported with the push plate; the push plate is supported with a base plate; a downward flaring structure is arranged at the lower end of the rear mold; the rear mold penetrates through the B plate, the push block and the push plate, and then is supported with the base plate; a cavity is reserved between the base plate and a bottom plate; and a connecting plate is mounted in the cavity.
Description
Technical field
The utility model relates to the technical field of structures of product mold, is specially a kind of first top strong demolding structure again of mould.
Background technology
Existing interior side ring surface is with the product to center back-off structure, its mould structure generally need to be combined by polylith line position mold insert, its mould structure complexity, cost of manufacture is high, and after the demoulding completes, also need corresponding structure is set, guarantee that polylith line position mold insert matched moulds puts in place, its matched moulds efficiency is low, makes the production efficiency of mould low.
Summary of the invention
The first top that the utility model provides a kind of mould is strong demolding structure again, and it makes the interior side ring surface can a demoulding with the product to center back-off structure, and mould structure is simple, cost of manufacture is low, and matched moulds is quick, has improved the production efficiency of mould.
The first top of mould is a strong demolding structure again, and its technical scheme is such: it comprises front mould, rear mold, A plate, B plate, rear mold mold insert, described front mould, rear mold, B plate, rear mold mold insert is combined to form die cavity, in described die cavity, is product, and the interior side ring surface of described product, with to center back-off structure, is characterized in that: described rear mold mold insert comprises outer ring surface mold insert, center mold insert, described B plate is supported on push pedal, and the upper end of pushing block is close in the lower surface of described die cavity, and described pushing block is supported on described push pedal, and described push pedal is supported on backing plate, and the lower end of described rear mold is downward flaring structure, and described rear mold runs through described B plate, pushing block, push pedal rear support, in described backing plate, leaves cavity between described backing plate and base plate, in described cavity, connecting plate is housed, and is provided with push rod through hole on described connecting plate, and top roller runs through respectively base plate from bottom to top, connecting plate, after backing plate, be fastenedly connected described push pedal, push rod runs through respectively backing plate from bottom to top, after rear mold, be close to the lower surface of described outer ring surface mold insert, screw is fastenedly connected push rod from bottom to top, outer ring surface mold insert, center mold insert, the fastening nylon deduction that is provided with in bottom of described push rod, described nylon buckles mantle is loaded in described push rod through hole, and the lower surface of described backing plate is welded with annular interstage sleeve for the outer ring surface of described push rod, the external diameter of the aperture >=described annular interstage sleeve of described push rod through hole.
It is further characterized in that: between the bottom end face of described nylon deduction, push rod, be provided with wear-resistant block, the outer ring surface of described wear-resistant block exposes to described push rod, the upper end of described wear-resistant block is towards the lower surface of described annular interstage sleeve, the external diameter of the aperture of described push rod through hole >=described wear-resistant block.
Adopt after structure of the present utility model, during the demoulding, front mould, A plate elder generation and B plate, rear mold completes separation, the power of injection machine push rod passes on the rod of top afterwards, connecting plate, push pedal, pushing block is up walked together, now due to the power of push rod bottom surface nylon deduction, push rod is also up walked, drive outer ring surface mold insert, center mold insert rises together, rear mold is motionless, product and rear mold depart from, when the upper surface that push rod rises to the nylon deduction of its lower end touch the lower surface of annular interstage sleeve, push rod is upper body again, now due to the external diameter of the aperture >=described annular interstage sleeve of push rod through hole, connecting plate continues to rise under the drive of top roller, product continues to rise, outer ring surface mold insert, mold insert position, center is fixed, and then the interior side ring surface of product with to center back-off structure by force with outer ring surface mold insert, the center mold insert generation demoulding, it makes the interior side ring surface can a demoulding with the product to center back-off structure, mould structure is simple, cost of manufacture is low, after product is removed, cleaning Wan Liao road, top roller is resetted, the demolding structure of back-off structure can complete matched moulds, matched moulds is quick, improved the production efficiency of mould.
