Abstract
The invention discloses a secondary parting mold structure for a movable die. The secondary parting mold structure comprises a fixed die seat plate, a fixed die fixed on the fixed die seat plate and a movable die matched with the fixed die, wherein the movable die comprises a push plate, a movable template and a supporting plate for fixing the movable template, and the push plate, the movable template and the supporting plate are sequentially superposed from top to bottom; a fixed die cavity connected with a pouring gate is formed in the fixed die; a movable die cavity is formed in the push plate; a movable die mold core is arranged on the movable template; the fixed die cavity, the movable die cavity and the movable die mold core are matched to form a mold cavity. The secondary parting mold structure also comprises a first separating mechanism for separating the push plate from the movable template and a second separating mechanism for separating the fixed die from the push plate. According to the secondary parting mold structure, the packaging force of a workpiece is decomposed through secondary parting, so that the defects of deformation, cracks and the like on the surface of the workpiece are eliminated when a mold pushes the workpiece; meanwhile, the secondary parting mold structure has the advantages of simplicity, low manufacturing cost, long service life and the like.
Description
Technical field
The invention belongs to plastics die cavity injection mold field, especially relate to a kind of dynamic model twice parting mould structure.
Background technology
In the plastic shaping process, for the mould of forming thin-walled Shell-Class product, in ejection process, easily make product produce the defects such as distortion, cracking, top convex closure.The measure of in the past taking has: 1, increase the pattern draft of goods, 2, to the polishing of mould parts high brightness, 3, adopt the secondary ejection mold structure; Increase die manufacturing cost and the comparatively complicated problem of structure but above measure exists, when the product surface quality is had relatively high expectations, adopt said mechanism comparatively complicated.
Summary of the invention
The purpose of this invention is to provide a kind of dynamic model twice parting mould structure, while having solved the existing mold die sinking, easily make thin-wall case class product produce the problem of the defects such as distortion, cracking, top convex closure.
The technical solution adopted for the present invention to solve the technical problems is: a kind of dynamic model twice parting mould structure, comprise top clamping plate, and be fixed on the cover half on top clamping plate, and the dynamic model coordinated with this cover half; Dynamic model comprises from top to bottom superimposed successively push pedal, moving platen and the fixing support plate of moving platen; Be provided with the cover half chamber be connected with cast gate on cover half, be provided with the dynamic model chamber in push pedal, be provided with dynamic mould core on moving platen, cover half chamber, dynamic model chamber coordinate the formation die cavity with dynamic mould core; Also comprise the first separating mechanism that push pedal is separated with moving platen, the second separating mechanism that cover half is separated with push pedal.
Further, the first separating mechanism comprises the stop screw be fixed in push pedal, and moving platen is provided with the confined planes coordinated with the nut of this stop screw; Described moving platen and support plate can move axially along stop screw.The second separating mechanism comprises the shutter be arranged on cover half and push pedal die joint.
In order to increase the durability of mould, also be provided with stop collar outside described stop screw.Be provided with fixed die insert on cover half, be provided with moving die insert in push pedal; Described cover half chamber is positioned at fixed die insert, and the dynamic model chamber is positioned at moving die insert.
Preferably, shutter is resin shutter, mechanical shutter or magnet shutter.
Beneficial effect of the present invention: by adopting shutter, control the sequencing that dynamic model is opened, control the stroke of parting for the first time according to the nut of stop screw to the distance of confined planes simultaneously, the package power of product is decomposed, thereby while guaranteeing the mould push piece, product surface, without defects such as distortion, crackings, reduces the damage of mould simultaneously; Further, the stop collar of cushioning effect has been set on stop screw, has avoided mould because long-term the use causes stop screw to drop out from push pedal, improved the reliability of mould.
Below with reference to drawings and Examples, the present invention is described in detail.
The accompanying drawing explanation
Fig. 1 is cutaway view of the present invention.
Fig. 2 is the present invention's working state schematic representation of somatotype for the first time.
Fig. 3 is the present invention's working state schematic representation of somatotype for the second time.
The specific embodiment
Embodiment, see also Fig. 1 to 3, and a kind of dynamic model twice parting mould structure, comprise top clamping plate 1, is fixed on the cover half 2 on top clamping plate 1, and the dynamic model coordinated with this cover half 2; Dynamic model comprises from top to bottom superimposed successively push pedal 31, moving platen 33 and the fixing support plate 34 of moving platen 33; Be provided with the cover half chamber be connected with cast gate on described cover half 2, be provided with the dynamic model chamber in push pedal 31, be provided with dynamic mould core 331 on moving platen 33, described cover half chamber, dynamic model chamber coordinate the formation die cavity with dynamic mould core 331; Also comprise the first separating mechanism that push pedal 31 is separated with moving platen 33, the second separating mechanism that cover half 2 is separated with push pedal 31.
Further, the first separating mechanism comprises the stop screw 32 be fixed in push pedal 31, and moving platen 33 is provided with the confined planes 35 coordinated with the nut of this stop screw 32; Described moving platen 33 can move axially along stop screw 32 with support plate 34; The second separating mechanism comprises the shutter 4 be arranged on cover half 2 and push pedal 31 die joints.
In order to increase the durability of mould, at described stop screw 32, be outside equipped with stop collar 36.Be provided with fixed die insert 21 on cover half 2, be provided with moving die insert 311 in push pedal 31; Described cover half chamber is positioned at fixed die insert 21, and the dynamic model chamber is positioned at moving die insert 311.
Preferably, shutter 4 is resin shutter, mechanical shutter or magnet shutter.
When the mould die sinking, due to effect moving platen and the first somatotype of push pedal of shutter, because dynamic mould core is fixed on moving platen, current somatotype can cause dynamic mould core to separate with product, and then eliminates the package power of dynamic mould core; After the distance of die sinking has for the first time reached spacing distance, mould continues die sinking, and when mould opening force is greater than the coupling mechanism force of shutter, cover half will separate with push pedal, until mould is opened pushing out product fully.The present invention decomposes the package power of product by twice parting, thereby while guaranteeing the mould push piece, product surface, without defects such as distortion, crackings, has the advantages such as simple in structure, low cost of manufacture, long service life simultaneously.
