Abstract
The invention discloses a plastic piece punching and cutting die, which comprises a cylinder, an upper die base plate, an upper die, a cutting-off cavity die, a pressure plate, a stripping plate, stripping springs, a punching head, a lower die and a lower die base plate. One end of the cutting-off cavity die is fixed inside the upper die base plate and is sleeved inside the upper die; cutting edges are obliquely and inwards formed on the surfaces at another end of the cutting-off cavity die; the pressure plate is movably sleeved in the cutting-off cavity die; a piston rod of the cylinder penetrates through the upper die base plate and is supported and pressed on the stripping plate; the stripping plate is in clearance sleeve connection with the punching head; the stripping springs are arranged between the stripping plate and the lower die base plate; and the lower die is fixed on the lower die base plate. As the cutting edges are obliquely and inwards formed on the surfaces at another end of the cutting-off cavity die, the blanking force for punching and cutting a plastic piece by using the plastic piece punching and cutting die is greatly reduced, the occurrence of the phenomena of spillover, cement extrusion and crushing of optical cement used for bonding plastic during the process of punching is better avoided, and the size of punched and cut products is stable and accurate.
Description
Technical field
The present invention relates to a kind of stamping die, particularly relate to a kind of working of plastics punching press knife edge die.
Background technology
As the new industry in the mobile phone industrial chain; handset touch panel is the main accessory of mobile phone; abundant circuit is contained in the inside; adopt the multilayer PET material and OCA is overlapping combines; after circuit printing applying is finished; need by the size shape by die-cutting; because abundant printed circuit is contained in the inside; common cross cutting traditional handicraft is to adopt laser cutting die or etching cutting die; because laser cutting die or etching cutting die machining accuracy are poor; rough surface, can cause clipped cut, circuit weigh wounded, overflow glue, draw phenomenons such as glue and size instability.The working of plastics die cutting device of commonly using is to realize by drift and cooperating of die, and the die-cut end of its die is flat mouthful, there is not cutting edge, it is bigger to cut pressure, causes easily to be used for overflowing, draw glue, weighing wounded of adhered plastics optical cement and the product size instability that forms.
Summary of the invention
The working of plastics punching press knife edge die of the object of the present invention is to provide a kind of optical cement to be difficult for overflowing, product size is stable.
For achieving the above object, technical solution of the present invention is:
The present invention is a kind of working of plastics punching press knife edge die, and it comprises cylinder, goes up baffle plate, patrix, cut-out die, holding pad, stripper plate, takes off and expect spring, drift, counterdie, following baffle plate; Described cylinder block is installed in the patrix plate outer side, the fixing baffle plate inboard of going up of patrix; Described cut-out die one end is fixed on the baffle plate inboard and is nested with in patrix, cuts off the oblique inside formation cutting edge in die other end surface, and cutting edge is inclination; Described holding pad activity is nested with in cutting off die; Described cylinder piston rod passes the patrix base top and is pressed on the holding pad; Described stripper plate gap is socketed on the drift, is provided with between stripper plate and following baffle plate and takes off the material spring, and counterdie is fixed on down on the baffle plate.
Described cylinder piston rod passes the patrix base top by connecting rod and is pressed on the holding pad.
After adopting such scheme, because the present invention is cutting off the oblique inside formation cutting edge of die other end edge surface, greatly reduce the blanking pressure of the die-cut working of plastics of the present invention, avoided the phenomenon of overflowing, drawing glue, weighing wounded of adhered plastics optical cement in the die-cut process to take place preferably, the dimensionally stable of die-cut product, accurate.In addition, binder mode of the present invention makes the cylinder binder into from traditional spring binder, reduces extruding to product with this, reaches adjustable in pressure, overcomes damage of circuit.This mould structure not only has characteristics such as dimensional stability, surface smoothness height, and long service life, adjustable in pressure, simple operation and other advantages.
The present invention is further illustrated below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is a front view of the present invention.
The specific embodiment
As shown in Figure 1, the present invention is a kind of working of plastics punching press knife edge die, and it comprises cylinder 1, last baffle plate 2, patrix 3, cuts off die 4, holding pad 5, stripper plate 6, takes off material spring 7, drift 8, counterdie 9, time baffle plate 10.
Described cylinder 1 cylinder body is installed in baffle plate 2 outsides, patrix 3 fixing baffle plate 2 inboards of going up; Described cut-out die 4 one ends are fixed on baffle plate 2 inboards and are nested with in patrix 3, cut off the oblique inside formation cutting edge 41 in die 4 other end dies surface, and cutting edge is inclination.
Described holding pad 5 activities are nested with in cutting off die 4; Described cylinder 1 piston rod passes baffle plate 2 roof pressures on holding pad 5 by connecting rod; Described counterdie 9 is fixed on down on the baffle plate 10.Stripper plate 6 gaps are socketed on the drift 8, and setting is taken off material spring 7 and taken off and expect that spring 7 passes the through hole on the counterdie between stripper plate 6 and following baffle plate 10.
Operation principle of the present invention:
1,With the method that the hardware stamping mould combines with the cutting die principle, adopt the structure of hardware stamping mould, overcome the difficult problem of machining accuracy, utilize the cutting die principle to reach keen edge.
,Drift 8 mold inserts adopt projection grinder, precision reaches 0.002, the surface reaches mirror effect, template adopts accurate slow silk processing, precision reaches 0.005, edge of a knife form adopts the oblique edge of a knife of cutting die, the cutting edge material that cutting die is used uses the mode of laser weld to be bumped in the five metals template earlier, re-use the silk of being careful, the curve mill, manufacturing process such as minute surface spark, template is processed into the structure that the five metals mould is promptly arranged has the mixed structure of cutting die characteristic again, so promptly have the stability of five metals mould, the keen edge of cutting die is arranged again, reduce blanking pressure with this, can overcome excessive glue, draw glue and weigh circuit wounded, can obtain stable size again.
3, the binder mode makes cylinder 1 binder into from traditional spring binder:
The traditional moulds technology is used the binder mode of spring, because pressure is non-adjustable, weighs circuit easily wounded, the present invention adopts cylinder 1 binder mode, make adjustable in pressure, weigh circuit because of pressure is excessive wounded or can't reach problems such as binder effect because of pressure is too small thereby overcome.
Emphasis of the present invention just is: cut off die and be provided with the inclination cutting edge.
The above, only for preferred embodiment of the present invention, so can not limit scope of the invention process with this, i.e. the equivalence of doing according to the present patent application claim and description changes and modification, all should still belong in the scope that patent of the present invention contains.
