Abstract
The utility model discloses a contraction internal core pulling mechanism for an injection mold, which comprises an auxiliary sliding block, a main sliding block, a sliding cavity, a spring, a sliding block pressing plate, a sliding block fixed plate, a core fixed plate and a core fixed plate guiding post, and is characterized in that the main sliding block, the auxiliary sliding block and the sliding core are respectively connected with a dovetail groove that forms an oblique angle with the mold opening direction, and a plurality of main sliding blocks and a plurality of auxiliary sliding blocks are uniformly distributed surrounding the sliding core, and the periphery of the main sliding block and the auxiliary sliding block is provided with the sliding block pressing plate. The internal core of the mould is produced into a sliding core of a guide rail of the dovetail groove and a plurality of main sliding blocks and a plurality of auxiliary sliding blocks, which can slide in an inclined direction corresponding to the sliding core, so that the product can be demolded through the simultaneous contraction of the main sliding blocks and the auxiliary sliding blocks; compared with the method for demolding the product by removing the movable core from the mold, not only the production efficiency is greatly improved, but also the size range of the product is greatly increased, thereby having remarkable economic benefit.
Description
Technical field
The present invention relates to a kind of core-pulling mechanism, refer in particular to a kind of contracting internal core withdrawing mechanism that is used for injection mold.
Background technology
When in plastic products, having the enclosure space shape of indent, plastic products can't be taken off from core after moulding, and present solution is to adopt moving core, behind product molding, moving core and goods together take off from mould, and then try every possible means core is taken out in the goods hole.Time-consuming, the effort of this method can't satisfy requirements of mass production.
Summary of the invention
The objective of the invention is to solve above-mentioned prior art problems, a kind of simple in structure, dependable performance, time saving and energy saving, the contracting internal core withdrawing mechanism that is used for injection mold that can satisfy requirements of mass production are provided.
The present invention is achieved in that
A kind of contracting internal core withdrawing mechanism that is used for injection mold, comprise auxilliary slide block, master slider, slide core, spring, slide block pressing plate, slide block fixed head, core fixing plate and core fixing plate guide pillar, described master slider, auxilliary slide block and slide core are respectively by being connected with dovetail groove that the die sinking direction has certain angle of inclination, the auxilliary slide block of polylith master slider and polylith is evenly distributed at the slide core periphery, the outer slide block pressing plate that is provided with around master slider and the auxilliary slide block.
The inclination angle of described auxilliary slide block dovetail groove is bigger than the inclination angle of master slider dovetail groove.
Described slide core is fixed on the core fixing plate, and core fixing plate is provided with can be for the chute of core fixing plate guide pillar slip.
Described slide core is fixed on the core fixing plate.
Described spring is installed between slide block fixed head and the core fixing plate.
Described master slider quantity be three and more than.
Described auxilliary slide block quantity be three and more than.
The present invention manufactures by the slide core of being with the dovetail groove guide rail by the interior core with mould and can produce the polylith master slider of oblique slip, auxilliary slide block with slide core, shrink in the time of by master slider and auxilliary slide block and reach the effect that makes the goods demoulding, with take off moving core from mould and carry out the mode that goods take off material and compare, not only improved production efficiency greatly, also increase the size range of goods greatly, had tangible economic benefit.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the relative position figure of major-minor slide block and slide core.
The specific embodiment
For being illustrated more clearly in technical scheme of the present invention, the present invention is further described below in conjunction with embodiment.
As shown in Figure 1 and Figure 2, a kind of contracting internal core withdrawing mechanism that is used for injection mold, comprise auxilliary slide block 4, master slider 5, slide core 6, spring 7, slide block pressing plate 8, slide block fixed head 9, core fixing plate 11 and core fixing plate guide pillar 12, described master slider 5 and slide core 6 are by becoming the dovetail groove at α inclination angle to be connected with the die sinking direction, auxilliary slide block 4 and slide core 6 are by becoming the dovetail groove at β inclination angle to be connected with the die sinking direction, the auxilliary slide block 4 of polylith master slider 5 and polylith is evenly distributed at slide core 6 peripheries, the outer slide block pressing plate 8 that is provided with around master slider 5 and the auxilliary slide block 4.
As shown in Figure 1, the angle of inclination beta of described auxilliary slide block 4 dovetail grooves is bigger than the inclined angle alpha of master slider 5 dovetail grooves.
As shown in Figure 1, described slide core 6 is fixed on the core fixing plate 11, and core fixing plate 11 is provided with can be for the chute 10 of core fixing plate guide pillar 12 slips.
As shown in Figure 1, described slide core 6 is fixed on the core fixing plate 11.
As shown in Figure 1, described spring 7 is installed between slide block fixed head 9 and the core fixing plate 11.
As shown in Figure 1, described master slider 5 quantity be three and more than, master slider 5 quantity of present embodiment are three.
As shown in Figure 1, described auxilliary slide block 4 quantity be three and more than, the quantity of the auxilliary slide block 4 of present embodiment is three.
As shown in Figure 1, mould is finished die sinking after the injection moulding, moving platen 16 and the core fixing plate guide pillar 12 that is fixedly mounted on the moving platen 16 move toward the die sinking direction, core fixing plate 11 is separated with slide block fixed head 9 by the active force of spring 7, drive slide core 6 and axially extract motion with master slider 5 and 4 generations of auxilliary slide block, because slide core 6 and master slider 5 and assist slide block 4 by being connected with dovetail groove that the die sinking direction has certain angle of inclination, can only produce by slide block fixed head 9 and 8 constraints of slide block pressing plate moves radially, and the angle of inclination beta of auxilliary slide block 4 dovetail grooves is bigger than the inclined angle alpha of master slider 5 dovetail grooves, it is faster than master slider 5 to make auxilliary slide block 4 extract in the motion cross-direction shrinkage speed to the center at slide core 6, thereby, shrink the back-off that makes on the goods 1 in the time of master slider 5 and auxilliary slide block 4 and be able to separate with back-off on the auxilliary slide block 4 with master slider 5 for the interior contraction of master slider 5 provides the space.Simultaneously, push pedal 15 drives to take off by ejector retainner plate 14 promotion thimbles 13 expects that mold insert 3 makes goods 1 separate with main core 2, realizes the demoulding.12 pairs of core fixing plates 12 of core fixing plate guide pillar carry out guide and limit with the disengaging movement of slide block fixed head under spring force promotes, avoid thimble 13 to be subjected to the cross force effect of core fixing plate 11.
The foregoing description is to further specify of the present invention, is not to concrete qualification of the present invention, therefore does the variation that is equal to according to the present patent application claim, is the scope that contains in the present invention.
