Abstract
The utility model discloses an injection mold the length slider structure of loosing core, including fixed die plate, movable mould board, slider mold insert, take -up housing, the piece of loosing core, the tight piece of contract, guide block, fixed die plate and movable mould board relative and establish, the guide block fix on the movable mould board, the slider mold insert is fixed in the inner of take -up housing, the take -up housing is installed on the movable mould board, take -up housing bottom and guide block cooperation motion, the fixing on the fixed die plate of the piece of loosing core, the piece of loosing core passes through the spout cooperation with the take -up housing to the removal of opening and shutting of drive slider, the tight piece of contract fix on the fixed die plate, outer end that the tight piece of contract pasted tight take -up housing guarantees that the slider does not become flexible under injection pressure, wear pad install the tight piece of contract go up just with the inclined plane close -fitting at the take -up housing back. Because the utility model discloses an oblique bone of loosing core on the piece has sufficient intensity, and is comparatively compact with take -up housing cooperation structure, can realize the long distance drawing of patterns of hydro -cylinder again, has that processing is simple, simple to operate, the long advantage of die life.
Description
Technical field
This utility model relates to a kind of injection mold, particularly relates to the distance pulled core structure of a kind of injection mould slide block.
Background technology
In traditional moulds in design, for the slide block that some stroke ratios are bigger, the structure of Angle Pin or oil cylinder is generally used to realize the demoulding of slide block.
Inclined pin structure: using Angle Pin structure under normal circumstances is a more satisfactory mode, but be intended to realize the slide block demoulding be accomplished by Angle Pin be designed to very wide-angle and also Angle Pin design is the longest, the design maximum angle of taper pin can only be at 20 degree under normal circumstances, about 10 times of a length of diameter, if the longest for Angle Pin design or very wide-angle, result is easily broken off, and has a strong impact on die life.
Cylinder structure: because oil cylinder volume is bigger, usually mold base can be strengthened for the installation of oil cylinder, processing oil cylinder mounting groove in the above, or design oil cylinder seat is set in mold base periphery, then being arranged on stand by oil cylinder, production process needs injection molding machine to increase oil gear.Cause die manufacturing cost to rise, and because the Outside Dimensions of whole mould strengthens, injection machine tonnage also to increase accordingly, causes the waste of board.
Summary of the invention
The purpose of this utility model be to provide a kind of compact conformation, process simple, easy for installation, die life length the distance pulled core structure of injection mould slide block.
For achieving the above object, technical solution of the present utility model is:
This utility model is the distance pulled core structure of a kind of injection mould slide block, including solid plate, moving platen, slide block insert, take-up housing, block of loosing core, the tight block of contract, guide pad；Described solid plate is relative with moving platen and sets；Described guide pad is fixed on moving platen, and slide block insert is fixed on the inner of take-up housing, and take-up housing is arranged on moving platen, with guide pad routing motion bottom take-up housing, loosing core being fixed on solid plate of block, block of loosing core is coordinated by chute with take-up housing, to drive the folding of slide block to move；The tight block of described contract is fixed on solid plate, and the tight block of contract is adjacent to the outer end of take-up housing, it is ensured that slide block does not loosens under injection pressure.
This utility model also includes limited block and wear plate；Described limited block is arranged on moving platen and is positioned at the end that take-up housing is opened；Described wear plate be arranged on the tight block of contract and with the inclined-plane close-fitting at the take-up housing back side.
The angle that described block of loosing core coordinates with slide block insert die sinking can realize 45 °.
After using such scheme, the parts such as slide block insert, take-up housing, block of loosing core, the tight block of contract, guide pad are included due to this utility model, the oblique bone loosed core on block has enough intensity, the compactest with take-up housing fit structure, the distance demoulding of oil cylinder can be realized again, have processing simple, easy for installation, die life length advantage.
With specific embodiment, this utility model is further described below in conjunction with the accompanying drawings.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model；
Fig. 2 is three-dimensional exploded view of the present utility model；
Fig. 3 is die sinking schematic diagram of the present utility model.
Detailed description of the invention
As shown in Figure 1-Figure 3, this utility model is the distance pulled core structure of a kind of injection mould slide block, including solid plate 1, moving platen 2, slide block insert 3, take-up housing 4, block 5 of loosing core, the tight block of contract 6, guide pad 7, limited block 8 and wear plate 9.
Described solid plate 1 is relative with moving platen 2 and sets.Described wear plate 9 is arranged on moving platen 1, guide pad 7 is fixed on moving platen 2, slide block insert 3 is fixed on the inner of take-up housing 4 and stretches into die cavity, the two bottom sides of take-up housing 4 is slipped at wear plate 9 end face being fixed on moving platen 2, in the middle part of take-up housing 4 bottom surface, guide chute 42 slips on guide pad 7, is provided with slide block briquetting 10 in take-up housing 4 both sides.The loose core upper end of block 5 is fixed on solid plate 1, and oblique bone 51 gap of block 5 bottom of loosing core is nested with in the chute 41 of take-up housing 4, and to drive take-up housing 4 to move back and forth, the maximum angle of the oblique bone in block 5 bottom 51 of loosing core is 45 °, highly can be increased or decreased according to demand.The upper end of the tight block of described contract 6 is fixed on solid plate 1, and the lower end of the tight block of contract 6 acts against the outer end of take-up housing 4.Described limited block 8 is arranged on moving platen 2 and is positioned at the end of take-up housing 4 motion track.
Operation principle of the present utility model:
Described block 5 of loosing core is similar to triangle, processes an oblique bone 51 to realize Angle Pin function at its side, because tiltedly bone 51 is connected with block 5 of loosing core, wants more preferably relative to Angle Pin intensity.Take-up housing 4 is provided with cavity that a block 5 of loosing core dodges and oblique bone 51 acts on chute 41.During die sinking, block 5 of loosing core is set aside movable slider seat 4 in the effect of injection machine and is realized the demoulding.
The above, it is only this utility model preferred embodiment, therefore can not limit, with this, the scope that this utility model is implemented, the equivalence change i.e. made according to this utility model claim and description with modify, all should still belong in the range of this utility model patent contains.
