Abstract
The utility model relates to a moulding oscillating bar structure which comprises a mould, a mould core, a fixed mould fixing plate, an oscillating bar and a supporting plate, wherein the mould core is installed in a cavity of the mould, the fixed mould fixing plate is arranged at the bottom of the mould, the upper end of the oscillating bar passes through the fixed mould fixing plate and then is arranged in the mould core while the lower end of the oscillating bar is connected to the supporting plate through a round pin, an arc-shaped block is arranged at the contact part of the upper end of the oscillating bar and the fixed mould fixing plate, and a quenching piece is arranged at the contact part of the lower end of the oscillating bar and the fixed mould fixing plate. According to the structure provided by the utility model, a plastic piece is ejected from the mould by virtue of the oscillating bar, the arc-shaped block, the quenching piece and the like when the mould is opened, so that the demoulding is convenient and efficient; the structure is simple, the length precision of the plastic piece can be improved and the demand on the appearance of the plastic piece can be satisfied.
Description
Technical field
The utility model relates to a kind of moulding swing-bar mechanism, belongs to injection mold technical field.
Background technology
In injecting products, can often run into some products, inner surface sidewall has localized indentation tongue or segmented thread etc., because its stripper distance is from generally all shorter, can greatly increase mould and manufacturing cost as loosed core with Angle Pin, therefore, need one can reduce costs and manufacture simple mechanism and solve the problems referred to above.
Utility model content
The utility model object is the moulding swing-bar mechanism that a kind of simple in structure, reliable in action is provided in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of moulding swing-bar mechanism, comprises mould, core, cover half fixed head, fork, gripper shoe; Described core is arranged in the die cavity of mould; Described cover half fixed head is arranged on mold bottom; Described fork upper end is arranged in core through cover half fixed head, and lower end is connected in gripper shoe by round pin; Described fork upper end and cover half fixed head contact position are provided with arc piece; Described fork lower end and cover half fixed head contact position are provided with a quenching part.
Preferably, the contact point of described quenching part and fork is circular-arc.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
A kind of moulding swing-bar mechanism of the utility model scheme, by settings such as fork, arc piece, quenching parts, realizes mould in the time of die sinking, plastic is ejected in mould, be convenient in demoulding fast, simple in structure, can improve the modest ability precision of plastic simultaneously and meet shape requirement.
Brief description of the drawings
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
Accompanying drawing 1 is the structural representation of a kind of moulding swing-bar mechanism of the present utility model;
Wherein: 1, mould; 2, core; 3, cover half fixed head; 4, fork; 5, gripper shoe; 6, die cavity; 7, round pin; 8, arc piece; 9, quenching part.
Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Accompanying drawing 1 is a kind of moulding swing-bar mechanism described in the utility model, comprises mould 1, core 2, cover half fixed head 3, fork 4, gripper shoe 5; Described core 2 is arranged in the die cavity 6 of mould 1; Described cover half fixed head 3 is arranged on mould 1 bottom; Described fork 4 upper ends are arranged in core 2 through cover half fixed head 3, and lower end is connected in gripper shoe 5 by round pin 7; Described fork 4 upper ends and cover half fixed head 3 contact positions are provided with arc piece 8; Described fork 4 lower ends and cover half fixed head 3 contact positions are provided with a quenching part 9; Described quenching part 9 is circular-arc with the contact point of fork 4.
In ejection process, in the time that cover half fixed head 3 is encountered on fork 4 downside inclined-planes, force fork 4 swing and make fork 4 deviate from side convex-concave to left; When matched moulds resets, fork 4 bezel facets are encountered core 2 and are forced fork 4 to fall back on original position to the right, like this in production fast in enormous quantities, fork 4 can wear and tear because constantly colliding or rub with core 2, this problem is by arranging arc piece 8 in fork 4 upper ends and cover half fixed head 3 contact positions, fork 4 lower ends and cover half fixed head 3 contact positions arrange quenching part 9 and solve, notify above-mentioned setting, in ejection process, fork 4 just promotes fork 4 downside inclined-planes using quenching part 9 as guiding fulcrum, thereby makes it extract this side convex-concave out; And in reset, fork 4 ramps lead taking arc piece 8 as fulcrum slide right pendulum fork 4 inclined-planes and core 2 inclined-planes are closely cooperated.
By settings such as fork 4, arc piece 8, quenching parts 9, realize mould 1 in the time of die sinking, plastic is ejected in mould, be convenient in demoulding fast, simple in structure, can improve the modest ability precision of plastic simultaneously and meet shape requirement.
Below be only concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, within all dropping on the utility model rights protection scope.
