Abstract
The utility model discloses a peripheral demolding mechanism for a plastic injection mold. The peripheral demolding mechanism comprises a demolding core mechanism, a cylindrical mold kernel, an ejection drive mechanism and a plurality of ejection rods, wherein the ejection rods are driven by the ejection drive mechanism along a stripping direction and do ejection actions; the demolding core mechanism consists of two demolding core units; each demolding core unit consists of a plurality of mold cores; a plurality of mold cores positioned in one demolding core unit and a plurality of mold cores positioned in the other demolding core unit are circumferentially arranged on the mold kernel in a staggering form; the included angle between the plurality of mold cores positioned in one demolding core unit and the shaft axis of the mold kernel is larger than the included angle between the plurality of mold cores positioned in the other demolding core unit and the shaft axis of the mold kernel; and the plurality of mold cores in the demolding mechanism are arranged into different inclination angles. Therefore, when the mold cores are moved on the mold kernel along the demolding direction, and a gap is formed between the top parts of any two adjacent mold cores, so that the defects that the mold cores are mutually collided and clamped and the like can be effectively overcome.
Description
Technical field
The utility model relates to a kind of mould emptier field of the product with back-off structure, relates in particular to a kind of all-round mould emptier of injection mold.
Background technology
In die design process; usually can run into some with the product of back-off structure; when its in die cavity after the moulding; need to carry out the demoulding by special mould emptier; but more existing mould emptiers, its core rod has identical angle of inclination, when core rod moves along stripping direction; gapless or gap are too small between adjacent two core rod tops, thus cause adjacent two core rods mutually collide, stuck.
Summary of the invention
In order to overcome defects, the utility model provides a kind of all-round mould emptier of injection mold, and this demolding structure can effectively prevent core rod collision, the defective such as stuck.
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of all-round mould emptier of injection mold, comprise demoulding core mechanism, the bar shape die, eject driving mechanism and ejected a plurality of push rods that driving mechanism drove and ejected action along number of unmolulding directions by described, described demoulding core mechanism is comprised of two demoulding core units, described each demoulding core unit forms by the polylith core rod, wherein, the polylith core rod that is arranged in a demoulding core unit circumferentially is staggered with the polylith core rod that is arranged in another demoulding core unit and is located on the described die, and the angle that is arranged in the polylith core rod of a demoulding core unit and die axial line is all greater than the angle of the polylith core rod that is arranged in another demoulding core unit and die axial line; All be formed with in addition the outer profile that the inner profile with product back-off position matches at the top of the polylith core rod that is arranged in these two demoulding core units, and all offer chute in the bottom of the polylith core rod that is arranged in these two demoulding core units, the corresponding slip of one end of described a plurality of push rods places described a plurality of chute, during the demoulding under the active force of described push rod the polylith core rod in these two demoulding core units endwisely slip and be located on the described die.
As further improvement of the utility model, the polylith core rod that is arranged in these two demoulding core units all includes a core rod body and the strip projection that protrudes from described core rod body surface, and offering a plurality ofly along its axially extended gathering sill at all sidewalls of described die, described each projection all corresponding the slip places the described gathering sill that is complementary with it.
As further improvement of the utility model, described ejecting includes a top board in the driving mechanism, and the other end of described a plurality of push rods all detachably is located on the described top board.
The beneficial effects of the utility model are: by the polylith core rod in the mould emptier is arranged to have different angles of inclination; when core rod moves along stripping direction on die like this; produce the gap between the top of adjacent two core rods, thereby can prevent effectively that core rod from colliding mutually, the defective such as stuck.
