Results show that the injection molding mould for manufacturing the upper cover of the cylinder body of the automobile engine is simple in structure and convenient to maintain, the cost of a large injection molding mould is lowered, the service life of the large injection molding mould is prolonged, producing efficiency is improved, and product quality is guaranteed.

Description

Lid injection mold on a kind of automobile engine cylinder-body
Technical field
The present invention relates to lid injection mold in Design of Dies technical field, more particularly to a kind of automobile engine cylinder-body.
Background technology
The characteristics of there is high production efficiency and various complicated shape products can be manufactured due to injection mo(u)lding, injection mo(u)lding Have become production plastic products most common method.Generally, injection mo(u)lding design includes that the design of plastic product, mould set The design of meter and Shooting Technique, these factors affects the quality and performance of mould product.Plastic is Hyundai Motor science and technology Progressive developing direction, plastic piece shaping technology is got up with plasticization of Automobile seamless combination, innovates and create forming technique.
Automobile engine cylinder-body is a plastic product, and cylinder body is different, and its corresponding superstructure is also different.Present people Focus on the simplification and innovation of lid injection mold structure on automobile engine cylinder-body, such as the technology people of Ningbo Shuanglin Die Co., Ltd Member devises a kind of core-pulling device of the car engine cover injection mold with side wall back-off structure, by simple several zero Part can just complete the core pulling process of baroque back-off structure, and simple structure, small volume can be realized flat along product side wall The horizontal core pulling in face can realize the horizontal core pulling of vertical product sidewall plane again.Technical staff's design of Dong Feng Auto Corporation technique center Mould using reversible deformation compensate, it is ensured that the dimensional accuracy of automotive engine cylinder cover plastic product.But the layout side of mould Formula is a cavity per mould, and productivity ratio is still not high enough.
Lid plastic product is an internal, outside plastic product with many places groove and hole on automobile engine cylinder-body, The part structure is more complicated, injection mold not easy mold release, for the longer hole inconsistent with die sinking direction is frequently with liquid in production Pressure side-parting core-pulling mechanism, increased operational sequence;And on existing automobile engine cylinder-body lid injection mold core Do not possess push piece function, mould structure is complicated, and manufacture is complicated, and maintenance is inconvenient, and the mold use life-span is low, and production cost is high, Low production efficiency, plastic product dimensional accuracy is low.
The content of the invention
It is an object of the invention to provide lid injection mold on a kind of automobile engine cylinder-body, be up to above-mentioned purpose, this It is bright to be achieved through the following technical solutions:
Lid injection mold on a kind of automobile engine cylinder-body, by the way of sound coordinates and combines, is fixed with Bottom clamp plate 1 Push pedal guide pillar 4, push pedal guide pillar 4 is slidably matched with ejector guide pillar 3, ejector guide pillar 3 and the stationary fit of push pedal 2, fixed on top clamping plate 8 There are Angle Pin 7, sprue bush 16, runner lock pin 21, curved pin 24, latch segment 27, band shoulder guide pin bushing 40 and range line pull bar 41, die cavity 9 with the stationary fit of solid plate 19, core 31 and the stationary fit of moving platen 32, be respectively equipped with cooling water channel on die cavity 9, core 31, and cold But water channel is provided with the removal hole of die cavity 9 away from mold cavity surface apart from equal on solid plate 19, and core 31 is provided with moving platen 32 Removal hole, Angle Pin 7 is slidably matched with side slide 5, and curved pin 24 is slidably matched with angled-lift splits 28, and side slide 5 is fixed with side core 6 Connection, angled-lift splits 28 is fixedly connected with oblique core 25, spring 42 be enclosed within the outside cylinder of range line pull bar 41 and with the phase of solid plate 19 Contact;
Tooth bar is made on cross depression bar, simplifies core-pulling mechanism.One end of cross depression bar 12 is slidably matched with pressing plate 11, cross pressure Bar 12 is connected with little spring 13, and the other end of cross depression bar 12 is provided with rack and pinion 14 and engages, gear 14 and little side core The tooth bar engagement at 10-end;By cross depression bar 12 and the collective effect of gear 14, by the little side type inconsistent with die sinking direction Core 10 is extracted out, simplifies core-pulling mechanism.
Further, wear-resistant block 33 is slidably matched with the bar portion of big inclined guide 23 and the bar portion of little inclined guide 20, auxiliary It is oriented to.
Further, the core for forming plastic medial surface shape is inlayed in the side of little inclined guide 20, big inclined guide 23, it is little tiltedly Guide rod 20 is engaged respectively with core 31, and large and small inclined guide constitutes combination type core with core.
Further, during die sinking, solid plate 19 is moved to left, and is separated with top clamping plate 8;At the same time, sprue condensate 17 with Sprue bush 16 is separated, and in the presence of runner lock pin 21, runner condensate 22 is pulled out;At the same time in the effect of gear 14 Under, little side core 10 is extracted, and in the presence of Angle Pin 7, side slide 5 drives side core 6 complete along the guide runner of moving platen 32 Into side core core pulling, in the presence of curved pin 24, angled-lift splits 28 drives oblique core 25 to complete oblique type along the guide runner of moving platen 32 Core core pulling works;Solid plate 19 continues to move to left, and when range line pull bar 41 is encountered, solid plate 19 stops movement;Continue dynamic model part Move to left, force shop bolt 39 to be deviate from from the pit of solid plate 19;Plastic bag on core 31 as dynamic model continues to move to left, directly Contact with push pedal 2 to injection machine push rod, push pedal 2 promotes ejector pin retaining plate 35, in the effect of little inclined guide 20 and big inclined guide 23 Under, the core pulling work inside plastic is realized, and little inclined guide 20 and big inclined guide 23 push away plastic jointly while core pulling Arc-shaped inner surface, little inclined guide 20, big inclined guide 23 and thimble 15 release plastic;During matched moulds, by shoulder leader pin 37 with Make without shoulder guide pin bushing 38 and band shoulder guide pin bushing 40, the accurate pairing of cover half two large divisions, and release link 36 makes ejecting mechanism reset;Tiltedly Guide pillar 7 makes side core 6 reset, and curved pin 24 makes oblique core 25 reset.
The invention has the beneficial effects as follows:The present invention replaces hydraulic core extracting machine using curved pin side core-drawing mechanism in structure Structure, the large and small inclined guide of employing can form the local shape of plastic, and ejecting mechanism can be done again, and the wear-resistant block for being used was both resistance to Mill is conveniently replaceable again.As a result show:Make the injection mold structure covered on automobile engine cylinder-body simple, it is easy to maintenance, reduce The cost of large injection mold, increased the service life of large mold, improve productivity ratio, it is ensured that the quality of product.
