Fig. 2 shows the cutaway view of the part of metal die according to an embodiment of the invention.
The specific embodiment
By following accompanying drawing and description, the features and advantages of the present invention will become apparent.
To with reference to accompanying drawing according to a particular embodiment of the invention metal die be described in more detail below.Irrelevant with figure number, identical or accordingly those parts be endowed identical Reference numeral, and omit unnecessary description.
Fig. 1 is the perspective view of metal die 1000 according to an embodiment of the invention, and Fig. 2 shows the cutaway view of the part of metal die 1000 according to an embodiment of the invention.As depicted in figs. 1 and 2, the metal die 1000 of present embodiment comprises nozzle unit 100, nozzle plate 210, connecting plate 220, molded panel 230, support member 150, false die cavity 224, first the air gap 310, second the air gap 320 and the 3rd the air gap 330.Therefore, metal die 1000 can prevent that heat is passed on the plate that adjoins from nozzle 130 according to an embodiment of the invention.
Metal die 1000 can have such form, and wherein, nozzle plate 210, connecting plate 220, molded panel 230 and a plurality of accessory plate 202,204,206,208,212,214 are stacked in the mode on.
The groove of support nozzle unit 100 can be formed in the nozzle plate 210.
Nozzle unit 100 can comprise nozzle 130, heating unit 120 and lining 140.
The service duct 110 that is used to supply resin can be formed in the nozzle 130.The heating unit 120 that is used to heat the resin that flows through service duct 110 can be formed on service duct 110 around.
Heating unit 120 can comprise heater strip, and this heater strip produces heat when the supply electric current.Service duct 110 with heating unit 120 can be known as hot flow path.
Nozzle 130 can be inserted in the lining 140.Lining 140 can have around nozzle 130 and can form the structure of the outside of nozzle unit 100.Here, the groove (that is first the air gap 310) that wherein is filled with air can be arranged between nozzle 130 and the lining 140.
First the air gap 310 can prevent that the heat of nozzle 130 is passed to nozzle plate 210, connecting plate 220 and the molded panel 230 that adjoins with nozzle 130.
Lining 140 can be supported by support member 150.Support member 150 can have longitudinal extension with the shape corresponding to the shape of nozzle unit 100, and wherein is formed with hollow space.Nozzle unit 100 can be inserted in the hollow space.
The end sections of lining 140 can form cone shape, its area of section is less towards the lower end, and the groove (that is second the air gap 320) that wherein is filled with air can be formed between the sloping portion of end sections of support member 150 and circular cone lining 140.Second the air gap 320 can prevent that the heat of nozzle 130 is passed to nozzle plate 210, connecting plate 220 and the molded panel 230 that adjoins with nozzle 130.
The nozzle plate 210 that support member 150 can be had groove supports, and can insert support member 150 in this groove.Nozzle plate 210 can hold support member 150 and support two end sections of this support member 150.
The groove (that is the 3rd the air gap 330) that wherein is filled with air can be formed between support member 150 and the nozzle plate 210.The 3rd the air gap 330 can prevent that the heat of nozzle 130 is passed to nozzle plate 210, connecting plate 220 and the molded panel 230 that adjoins with nozzle 130.
Connecting plate 220 can be coupled to the upper end of molded panel 230.According to the position of service duct 110 and the interface channel 222 that passes connecting plate 220 vertically can be formed in the connecting plate 220.
Interface channel 222 can place between molding cavity 232 (back will be described) and the service duct 110 and a path is provided, and the resin that discharges by service duct 110 can be injected in the molding cavity 232 by this path.Here, the passage that is similar to the interface channel 222 that does not have heater can be known as cold runner.
False die cavity 224 can be formed on the upper surface that is positioned at interface channel 222 connecting plate 220 on every side.False die cavity 224 can provide the space between service duct 110 and interface channel 222, resin can be filled in this space.
After resin was filled in the false die cavity 224, the resin that discharges by service duct 110 can be injected in the molding cavity 232 through interface channel 222.
If sloppy heat slag (it is the resin through service duct 110 initial ejections) directly is filled in the molding cavity 232, then because flowing of sloppy heat slag is smooth and easy inadequately, so the sloppy heat slag may cause the defective in the mechanograph.Yet the metal die 1000 of present embodiment can prevent the defective in the mechanograph, and this is because the sloppy heat slag of its initial ejection is filled in the false die cavity 224.
In addition, the resin that is filled in the false die cavity 224 can and can prevent that the heat of nozzle 130 is passed to connecting plate 220 and molded panel 230 as the barrier material between nozzle unit 100 and the connecting plate 220.
Molded panel 230 can be coupled to the end portion of connecting plate 220.Molding cavity 232 with given shape can be formed in the corresponding part in the position with interface channel 222 of molded panel 230.Molding cavity 232 can be filled by resin, and resin can be had the mechanograph of given shape with formation by sclerosis in molding cavity 232.
Therefore, because the metal die 1000 of present embodiment has first the air gap 310, second the air gap 320, the 3rd the air gap 330 and false die cavity 224, can prevent that the heat of nozzle 130 is passed to nozzle plate 210, connecting plate 220 and the molded panel 230 that adjoins with nozzle 130.This has prevented to produce thermal stress in metal die 1000.
In addition, because false die cavity 224 holds the sloppy heat slag through service duct 110 initial ejections, so can prevent to produce the defective of the mechanograph that can cause by the sloppy heat slag of initial ejection.
According to embodiments of the invention, can prevent that the heat of nozzle is passed to the other parts of the metal die that adjoins with nozzle.
Though described spirit of the present invention in detail with reference to specific embodiment, these embodiment only are used for illustration purpose and can't limit the present invention.Be appreciated that under the situation that does not depart from scope and spirit of the present invention, those skilled in the art can change these embodiments or revise.
Equally, the many embodiment except setting forth above can find in appending claims.
