This scheme provides a rattan chair mould mechanism of loosing core, the compact structure of loosing core, and occupation space is few, and the direction is accurate.
Description
Technical field
The utility model relates to a kind of rattan chair Mold Core-pulling Mechanism, belongs to mould applications.
Background technology
Rattan chair mould back-rest potential head portion draws in, and form multiple arc-shaped side, relative pulled core structure is more complicated, easily occurs the problems such as guiding inaccuracy.
Summary of the invention
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of rattan chair Mold Core-pulling Mechanism, and pulled core structure is compact, occupies little space, and guiding accurately.
For achieving the above object, the utility model provides following technical scheme: a kind of rattan chair Mold Core-pulling Mechanism, comprise cope match-plate pattern and lower bolster, rattan chair backrest injection moulding die cavity is formed between cope match-plate pattern and lower bolster, this injection moulding die cavity comprises the arc-shaped side chamber being positioned at die cavity both sides, arc core bar is combined with in arc-shaped side chamber, stroke plate is fixed with outside described lower bolster, stroke plate is provided with arc-shaped guide rail, the slippage of described arc core bar is engaged on arc-shaped guide rail and head stretches into arc-shaped side chamber, arc core bar afterbody on arc-shaped side chamber, die cavity both sides is hinged with pull bar respectively, two pull bar other ends are hinged on one stroke block, stroke block is between arc-shaped guide rail, the slippage of stroke block is engaged on a longitudinal rail, stroke block is combined with oil cylinder of loosing core.
Preferably, described stroke plate is provided with boss, and boss is between arc-shaped guide rail, and boss head is provided with the locating slot of shape and stroke block adaptation, and stroke block and locating slot are all square.
Preferably, described in the loose core piston rod head of oil cylinder to be threaded adjusting rod, the adjusting rod other end is rotatably connected on stroke block.
Preferably, the guide rail of described arc-shaped guide rail and longitudinal rail to be all cross section be T-shaped.
By adopting technique scheme, the arc core bar that oil cylinder of loosing core controls die cavity both sides is respectively synchronized with the movement, and motion synchronicity is good simultaneously to decrease the quantity of oil cylinder, and the demoulding is quick; Below stroke block, longitudinal rail is set, with arc-shaped guide rail synchronization steering, ensures the accuracy of stroke block motion and the accurate demoulding of arc core bar.

Detailed description of the invention
A kind of rattan chair Mold Core-pulling Mechanism, comprise cope match-plate pattern and lower bolster 2, rattan chair backrest injection moulding die cavity is formed between cope match-plate pattern and lower bolster 2, this injection moulding die cavity comprises the arc-shaped side chamber 11 being positioned at die cavity both sides, arc core bar 10 is combined with in arc-shaped side chamber 11, stroke plate 3 is fixed with outside lower bolster 2, stroke plate 3 is provided with arc-shaped guide rail 6, the slippage of described arc core bar 10 is engaged on arc-shaped guide rail 6 and head stretches into arc-shaped side chamber 11, arc core bar 10 afterbody on arc-shaped side chamber, die cavity both sides 11 is hinged with pull bar 4 respectively, two pull bar 4 other ends are hinged on one stroke block 12, stroke block 12 is between arc-shaped guide rail 6, stroke block 12 slippage is engaged on a longitudinal rail 8, stroke block 12 is combined with oil cylinder 7 of loosing core.The arc core bar 10 that oil cylinder 7 of loosing core controls die cavity both sides is respectively synchronized with the movement, and motion synchronicity is good simultaneously to decrease the quantity of oil cylinder, and the demoulding is quick; Longitudinal rail 8 is set below stroke block 12, with arc-shaped guide rail 6 synchronization steering, ensures the accurate demoulding of the accuracy that stroke block 12 moves and arc core bar 10.
Wherein, stroke plate 3 is provided with boss 5, and boss 5 is between arc-shaped guide rail 6, and boss 5 head is provided with the locating slot 13 of shape and stroke block 12 adaptation, and stroke block 12 and locating slot 13 are all square.Stroke block 12 is advanced inward by inlay card on locating slot 13, and locating slot 13 limits moving left and right of stroke block 12, and can ensure product injection moulding out size is accurate when matched moulds.
Wherein, piston rod 9 head threads of oil cylinder 7 of loosing core is connected with adjusting rod 14, and adjusting rod 14 other end is rotatably connected on stroke block 12.The extension of adjusting rod 14 seat piston rod 9 length, according to circumstances suitably rotates to adjust length, comprises stroke block 12 emphasis and just in time conflict on locating slot 13 diapire.
Wherein, the guide rail of arc-shaped guide rail 6 and longitudinal rail 8 to be all cross section be T-shaped.T-shaped guide rail guiding is accurately steady, convenient processing and manufacture.
