Description

The mould of quincunx townhouse formula plastic pin
Technical field
The utility model relates to mould for plastics, is specifically related to a kind of quincunx plastic pin mould.
Background technology
Growing along with commodity economy, drop is used more and more at large, with drop be fixed on the commodity be by plastic pin as connector, therefore, the demand of plastic pin increases thereupon.The plum blossom head of quincunx plastic pin is complex-shaped, and plastic pin is elongate, and the diameter at the rectangular position, centre of plastic pin is about Φ 0.5mm, so the moulding difficulty is big.As everyone knows, when the wall thickness value of working of plastics was too small, the pressure loss during injection was bigger, and stream is long than little, the plastics premature hardening, thus can cause the defective of working of plastics lack of fill.Therefore, the structural design to mould has higher requirement.
The utility model content
At the problems referred to above, the utility model provides a kind of mould of quincunx townhouse formula plastic pin, comprise upper mounted plate 1, front mould 2, back mould 5, gripper shoe 6, scraping wings 7, mould pin 8 and bottom plate 12, it is characterized in that: front mould 2 is fixed on the upper mounted plate 1, form quincunx die cavity 3 when described front mould 2 and back mould 5 closures, be provided with gripper shoe 6 between described scraping wings 7 and the back mould 5, scraping wings 7 connects two mould pin 8, be fixedly connected with plate 11 in two mould pin 8 and the back mould on the bottom plate 12, upper ejector plate 9 is fixed in the mould of back on the plate 11 by screw, plate 11 and upper ejector plate 9 are between two mould pin 8 in the mould of described back, be fixedly connected with return pin 10 in the back mould on the plate 11, return pin 10 connects and passes upper ejector plate 9 and be connected to back mould 5, the outside of back mould 5 is fixedly connected with limited block 13 by screw, the outside of front mould 2 is fixedly connected with the limit guide rail 14 of T type by screw, and in the mold work process, limited block 13 can move both vertically along limit guide rail 14.
Be fixedly connected with thimble 4 on the described gripper shoe 6, ejecting of thimble 4 held the corresponding afterbody that is connected to quincunx die cavity 3 when mould was closed.
Compared with prior art, useful technique effect of the present utility model is: well-known, the pushing method of moulding is to quality and the production efficiency important influence of product, the utility model is because quincunx townhouse plastic pin is thin-walled small size part, therefore, shape facility according to product has designed rational plastic pushing method, be front mould 2 and back mould 5 somatotype die sinkings, because the inertia force effect of matched moulds, after limit lock 16 is idle stroke 5-6mm, product namely separates with front mould 2, by return pin 10, the distance of the Stroke Control front mould 2 of limited block 13 and back mould 5 somatotypes, after product broke away from front mould 2, plastic pin was stayed in the die cavity of back mould 5, and the ejecting mechanism that is made of scraping wings 7 and thimble 4 simultaneously just pushes away die cavity with the quincunx plastic pin of townhouse formula with less thrust.The design of mould structure of the present utility model make eject the action smooth and easy, reduced the thrust that thimble applies when ejecting plastic, avoided ejecting the product quality defect that brings, be a kind of energy-conservation, reliable pushing method.
Description of drawings
Accompanying drawing 1 is front view,
Accompanying drawing 2 is vertical view,
Accompanying drawing 3 is left view.
Among the figure, 1. upper mounted plate, 2. front mould, 3. quincunx die cavity, 4. thimble, 5. back mould, 6. gripper shoe, 7. scraping wings, 8. mould pin, 9. upper ejector plate, 10. return pin, plate in the 11. back moulds, 12. bottom plates, 13. limited blocks, 14. limit guide rail, 15. guide pillars, 16. limits lock.
The specific embodiment
The accompanying drawings specific embodiment of the present utility model.The technical scheme that the utility model adopts is: the mould of quincunx townhouse formula plastic pin, comprise upper mounted plate 1, front mould 2, back mould 5, gripper shoe 6, scraping wings 7, mould pin 8 and bottom plate 12, front mould 2 is fixed on the upper mounted plate 1, form the forming cavity of two quincunx plastic pins of townhouse formula when described front mould 2 and back mould 5 closures, be provided with gripper shoe 6 between described scraping wings 7 and the back mould 5, scraping wings 7 connects two mould pin 8, be fixedly connected with plate 11 in two mould pin 8 and the back mould on the bottom plate 12, upper ejector plate 9 is fixed in the mould of back on the plate 11 by screw, plate 11 and upper ejector plate 9 are between two mould pin 8 in the mould of described back, be fixedly connected with return pin 10 in the back mould on the plate 11, return pin 10 connects and passes upper ejector plate 9 and be connected to back mould 5, the outside of back mould 5 is fixedly connected with limited block 13 by screw, the outside of front mould 2 is fixedly connected with the limit guide rail 14 of T type by screw, in the mold work process, limited block 13 can move both vertically along limit guide rail 14.
Working process of mould of the present utility model is: matched moulds-injection-pressurize-cooling-die sinking, front mould 2 are mobile under the effect of injector folding modular system, in die joint place and back mould 5 closures, guarantee that by guide pillar 15 and limit lock 16 mould is accurately closed; The injector injection filling mould, plastic melt flows into quincunx die cavity 3 through runner system, by the interstitial row of die joint and thimble 4 parts except the gas in the mould, thereby be full of quincunx die cavity 3; Pressurize after die cavity is filled with is shunk with the cooling that replenishes plastics; The quincunx plastic pin cooling and shaping of townhouse formula in the mould; After the plastic pin cooling that the townhouse formula is quincunx, folding modular system by injector drives front mould 2 and back mould 5 somatotype die sinkings, because the inertia force effect of matched moulds, after limit lock 16 is idle stroke 5-6mm, product namely separates with front mould 2, distance by the Stroke Control front mould 2 of return pin 10, limited block 13 and back mould 5 somatotypes, after product breaks away from front mould 2, plastic pin is stayed in the die cavity of back mould 5, the ejecting mechanism that is made of scraping wings 7 and thimble 4 simultaneously just pushes away die cavity with the quincunx plastic pin of townhouse formula with less thrust, thereby finishes an action cycle.The quincunx plastic pin of townhouse formula to eject in the process mold actions smooth and easy, energy-conservation, avoided product defective in the process of ejecting, to occur, improved the stability of product quality.This mould structure is reliable, and the die sinking system acting flexibly, steadily. ?
