Abstract
The invention provides a time delay core pulling die structure of a sliding block. By using the time delay core pulling die structure, the sliding block can be ensured to be subjected to accurate core pulling after a front die and a back die are opened; and furthermore, the structure is simple and the manufacturing cost is low. The time delay core pulling die structure comprises a front die kernel, a back die kernel, a plate A, a plate B, a die cavity and a sliding block seat; the die cavity is arranged between the front die kernel and the back die kernel; the sliding block seat is supported on the plate B; one end of the sliding block seat is connected with a slide core puller; and the slide core puller penetrates into the die cavity. The time delay core pulling die structure is characterized in that the plate A is firmly connected with the upper part of a square oblique guiding post; the outer side of the sliding block seat is an oblique plane; an oblique guiding post mounting hole is arranged inside the sliding block seat; vertical gaps L are reserved in the square oblique guiding post and the oblique guiding post mounting hole; and the plate B is provided with a mounting cavity.
Description
Technical field
The present invention relates to the technical field of mould structure, be specially slide block time-delay core-pulling die structure.
Background technology
The article construction that has need to be after the front and back mould be opened, the slide block action of loosing core again, and existing this kind mould structure complexity, cost of manufacture are high.
Summary of the invention
For the problems referred to above, the invention provides slide block time-delay core-pulling die structure, after mould was opened before and after it was guaranteed, slide block can accurately loose core, and simple in structure, cost of manufacture is low.
Slide block time-delay core-pulling die structure, its technical scheme is such: it comprises front cavity, rear cavity, the A plate, the B plate, die cavity, take-up housing, described front cavity, it is die cavity between the rear cavity, described take-up housing is supported on described B plate, described take-up housing one end connects line position and looses core, described line position is loosed core and is goed deep into described die cavity, it is characterized in that: described A plate is fastenedly connected the top of square Angle Pin, the outside of described take-up housing is the inclined-plane, the inside of described take-up housing has the Angle Pin installing hole, leave one section down suction L in described square Angle Pin and the Angle Pin installing hole, described B plate has installation cavity, do not loose core state under the bottom skewback of square Angle Pin be positioned at installation cavity, in the space of Angle Pin installing hole, the inboard inclined-plane of locating piece is close on the inclined-plane, the outside of described take-up housing, and the upper end of described locating piece is fastenedly connected described A plate.
It is further characterized in that: the lower end, the outside of described Angle Pin installing hole is that inclined-plane, upper end are vertical plane, the inside lower end of described Angle Pin installing hole is that vertical plane, upper end are the inclined-plane, the bottom of described square Angle Pin is skewback, the gradient of the inboard inclined-plane of described Angle Pin installing hole, inclined-plane, the outside and described skewback, oblique identical.
After adopting said structure of the present invention, leave an intersegmental crack in square Angle Pin and the Angle Pin installing hole, this moment, mould was opened, square Angle Pin does not work to take-up housing, and when current rear mold was opened to distance L, square Angle Pin contacted with Angle Pin installing hole in the take-up housing, mould continues to open, square Angle Pin is stirred slide block and is done side core-pulling, after mould was opened before and after it was guaranteed, slide block can accurately loose core, and simple in structure, cost of manufacture is low.
