Description
Technical field
The utility model relates to injection mold field, especially relates to a kind of handle injection mould pulled core structure.
Background technology
Technology of die manufacturing, is a more traditional development industry, along with social development, increasing for the update demand of mould, also more and more higher for the precision prescribed of mould.Conventionally, mould with pin point gate is arranged on dynamic model due to cover half somatotype complexity by ejecting mechanism, but in some cases, after determining spot pouring mouth position, will cause forming part to be greater than at dynamic model package power at the package power of cover half, now can only change spot pouring mouth position as can not be ejecting mechanism be set at cover half.
For can be smoothly taking out being smoothly placed in loosing core in product, conventionally adopt repeatedly the mould structure of somatotype, product is peeled away successively, but such mould is relatively complicated, and cost is high.
Utility model content
The purpose of this utility model is to provide a kind of handle injection mould pulled core structure and adopts the handle of this pulled core structure processing, solves existing handle and looses core too deeply, while taking-up, forms vacuum in core-drawing hole when loosing core, and Core-pulling force is large, and handle holds flimsy problem.
The utility model solves the technical scheme that its technical problem adopts: a kind of handle injection mould pulled core structure, comprise front template and rear pattern plate, be arranged on the front mould mold insert in front template, be arranged on the rear mold mold insert in rear pattern plate, front mould mold insert and rear mold mold insert will form the die cavity of handle moulding; The both sides that described rear pattern plate is positioned at die cavity are respectively provided with a transverse slider, and the front end of transverse slider is provided with cross bar, and cross bar is placed in die cavity; On described front template, be provided with two Angle Pins, be provided with the hole suitable with Angle Pin on transverse slider, when mould is closed, Angle Pin is placed in hole;
Described rear pattern plate is also provided with longitudinal sliding block along the handle direction of loosing core, and is provided with a curved wedge on described front template, is provided with the hole suitable with curved wedge on described longitudinal sliding block, and curved wedge is through the hole on longitudinal sliding block.
Accurate for ensureing the motion of slide block, on described transverse slider and longitudinal sliding block, be provided with protruding slide rail, on described rear pattern plate, be provided with the chute suitable with slide rail.
Preferably, the angle of described Angle Pin and vertical direction is between 20 °～45 °.
The handle that adopts above-mentioned handle injection mould pulled core structure processing, is provided with core-drawing hole on described handle, is provided with two passages on the hole wall of core-drawing hole.
The beneficial effects of the utility model: form through hole on the inwall of loosing core at handle by cross bar, make at handle in the time loosing core, the rear end of loosing core can not form vacuum, the pulling force that reduces to loose core while taking-up, ensures that handle can be because of stressed not excessive and damage.Described Angle Pin drives transverse slider motion, and simple in structure, easy to process, described curved wedge is simple in structure, coordinates reliably with longitudinal sliding block, and processing cost is low.
Below with reference to drawings and Examples, the utility model is described in detail.

Detailed description of the invention
Embodiment, as shown in Figures 1 to 3, a kind of handle injection mould pulled core structure, comprise front template 1 and rear pattern plate 2, be arranged on the front mould mold insert 3 in front template 1, be arranged on the rear mold mold insert 4 in rear pattern plate 2, front mould mold insert 3 will form the die cavity of handle moulding with rear mold mold insert 4; The both sides that described rear pattern plate 2 is positioned at die cavity are respectively provided with a transverse slider 5, and the front end of transverse slider 5 is provided with cross bar 6, and cross bar 6 is placed in die cavity; On described front template 1, be provided with two Angle Pins 7, be provided with the hole suitable with Angle Pin 7 on transverse slider 5, when mould is closed, Angle Pin 7 is placed in hole; Described rear pattern plate 2 is also provided with longitudinal sliding block 8 along the handle direction of loosing core, and the front end of longitudinal sliding block 8 is provided with looses core 14, looses core 14 to be placed in die cavity; On described front template 1, be provided with a curved wedge 9, be provided with the hole suitable with curved wedge 9 on described longitudinal sliding block 8, curved wedge 9 is through the hole on longitudinal sliding block 8.
For ensureing that transverse slider 5 and longitudinal sliding block 8, according to design route motion, are provided with protruding slide rail 10 on described transverse slider 5 and longitudinal sliding block 8, on described rear pattern plate 2, be provided with the chute suitable with slide rail 10.
Preferably, the angle of described Angle Pin 7 and vertical direction is between 20 °～45 °.
When after the injection mo(u)lding of mould close handles, open front template, front template drives Angle Pin to move together front template is separated with rear pattern plate with curved wedge, while just opening, because longitudinal sliding block first coordinates with the straightway part of curved wedge, curved wedge does not act on longitudinal sliding block, and longitudinal sliding block is not transported merit.Transverse slider to two lateral movements, makes cross bar depart from die cavity under the effect of Angle Pin, forms passage on handle.Mould continues to separate, and in the time that the dogleg section of curved wedge props up longitudinal sliding block, curved wedge continues motion, and longitudinal sliding block is outwards motion under the effect of curved wedge, and the disengaging die cavity that makes to loose core, separates with handle.Due to the effect of passage, make to loose core and handle between package power reduce, the taking-up of conveniently loosing core.Prevent handle in the time loosing core because of stressed excessive damage, improve product percent of pass.
As shown in Figure 4, adopt the handle of above-mentioned handle injection mould pulled core structure processing, it is characterized in that: on described handle 11, be provided with core-drawing hole 12, on the hole wall of core-drawing hole 12, be provided with two passages 13.When handle injection moulding, air enters in the core-drawing hole 12 of 14 rear ends of loosing core by passage 13, and 14 rear ends that prevent from loosing core form vacuum, and the power of 14 taking-ups that make to loose core reduces, and avoids handle because of stressed excessive damage.
The utility model can be widely used in the moulding deep hole field of loosing core, and what this class formation of every use was loosed core all belongs to protection domain of the present utility model.
