Description
Technical field
The present invention relates to injection mold field, the handle especially relating to a kind of handle injection mould pulled core structure and adopt this pulled core structure to process.
Background technology
Technology of die manufacturing, be a more traditional development industry, along with the development of society, the update demand for mould is increasing, and the precision prescribed for mould is also more and more higher.Usually, ejecting mechanism is arranged on dynamic model due to cover half somatotype complexity by mould with pin point gate, but in some cases, after determining spot pouring mouth position, the package power causing forming part at cover half is greater than at dynamic model package power, now can only changes spot pouring mouth position as ejecting mechanism can not be arranged at cover half.
For taking out being placed in loosing core in product smoothly smoothly, usually adopt repeatedly the mould structure of somatotype, being peeled away by product successively, but such mould is relatively complicated, cost is high.
Summary of the invention
The object of this invention is to provide a kind of handle injection mould pulled core structure, solve existing handle and loose core too dark, when taking out when loosing core, form vacuum in core-drawing hole, Core-pulling force is large, and handle holds flimsy problem.
The technical solution adopted for the present invention to solve the technical problems is: 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 shaping die cavity of handle; 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; Described front template is provided with two Angle Pins, transverse slider is provided with the hole suitable with Angle Pin, when mould closes, Angle Pin is placed in hole;
Described rear pattern plate is also provided with longitudinal sliding block along handle direction of loosing core, and described front template is provided with a curved wedge, described longitudinal sliding block is provided with the hole suitable with curved wedge, and curved wedge is through the hole on longitudinal sliding block.
Accurate for ensureing the motion of slide block, described transverse slider and longitudinal sliding block are provided with protruding slide rail, described rear pattern plate is provided with the chute suitable with slide rail.
Preferably, the angle of described Angle Pin and vertical direction is between 20 ° ~ 45 °.
The handle adopting above-mentioned handle injection mould pulled core structure to process, described handle is provided with core-drawing hole, and the hole wall of core-drawing hole is provided with two passages.
Beneficial effect of the present invention: the inwall of being loosed core at handle by cross bar forms through hole, and make at handle when loosing core, the rear end of loosing core can not form vacuum, reduces the pulling force of loosing core when taking out, and ensures that handle can not because of stressed excessive and damage.Described Angle Pin drives transverse slider motion, and structure is simple, easy to process, and described curved wedge structure is simple, and coordinate reliably with longitudinal sliding block, processing cost is low.
Below with reference to drawings and Examples, the present invention is described in detail.
Accompanying drawing explanation
Fig. 1 is the transverse sectional view at transverse slider place of the present invention.
Fig. 2 is the longitudinal sectional view at the curved wedge place of the present invention.
Fig. 3 is partial exploded view of the present invention.
Fig. 4 is the perspective view of handle.
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 and rear mold mold insert 4 will form the shaping die cavity of handle; 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; Described front template 1 is provided with two Angle Pins 7, transverse slider 5 is provided with the hole suitable with Angle Pin 7, when mould closes, Angle Pin 7 is placed in hole; Described rear pattern plate 2 is also provided with longitudinal sliding block 8 along 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; Described front template 1 is provided with a curved wedge 9, described longitudinal sliding block 8 is provided with the hole suitable with curved wedge 9, curved wedge 9 is through the hole on longitudinal sliding block 8.
For ensureing that transverse slider 5 and longitudinal sliding block 8 are according to design route motion, described transverse slider 5 and longitudinal sliding block 8 are provided with protruding slide rail 10, described rear pattern plate 2 is 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 drive Angle Pin moves together with curved wedge and front template is separated with rear pattern plate, when just opening, because longitudinal sliding block first coordinates with the straight length portion of curved wedge, curved wedge does not act on longitudinal sliding block, and longitudinal sliding block does not transport merit.Transverse slider to two lateral movements, makes cross bar depart from die cavity, handle forms passage under the effect of Angle Pin.Mould continues to be separated, and when the dogleg section of curved wedge props up longitudinal sliding block, curved wedge continues motion, and longitudinal sliding block outwards moves under the effect of curved wedge, makes disengaging die cavity of loosing core, is separated with handle.Due to the effect of passage, make to loose core and package power between handle reduces, the taking-up of conveniently loosing core.Preventing handle when loosing core because of stressed excessive and damage, improving product percent of pass.
As shown in Figure 4, the handle adopting above-mentioned handle injection mould pulled core structure to process, is characterized in that: described handle 11 is provided with core-drawing hole 12, and the hole wall of core-drawing hole 12 is provided with two passages 13.During handle injection moulding, air is entered by passage 13 looses core in the core-drawing hole 12 of 14 rear ends, 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 and damage.
The present invention can be widely used in moulding deep hole and to loose core field, and what this class formation of every use carried out loosing core all belongs to protection scope of the present invention.
