Description
Technical field
The present invention relates to a kind of moulding injection moulding process technology, particularly a kind of thin little moulding method for mold-unloading and cooling and pickup plate.
Background technology
A kind of mobile phone key is processed by transparent PC material, and the about 1mm of its thickness adopts the one-mold multiple-member injection mo(u)lding, and the moulding after the moulding is as shown in Figure 1, and it comprises button 10 and the running channel that is connected button 10 20.Its Shooting Technique is following: (1) matched moulds; (2) heat mould is heated, make to reach forming temperature; (3) injection; (4) cooling is cooled off mould, makes to reach the die sinking temperature; (5) die sinking pickup.Said die sinking pickup adopts manipulator to draw through vacuum pickup plate; Said pickup plate such as Fig. 2, shown in Figure 3; Fit in regular turn by channel plate 1, vacuum suction disc 2 and fixed head 3 and to assemble; The lateral surface of said channel plate 1 is provided with vaccum suction pipe 4, and the another side of fitting with said vacuum suction disc 2 is provided with the grooved passage 5 that is communicated with vaccum suction pipe 4, and said vacuum suction disc 2 is provided with the suction part that is communicated with said grooved passage 5 with said fixed head 3 binding faces and chews 6; Described fixed head 3 is provided with and supplies said suction part to chew the 6 suction parts that wear to chew through hole 7, and said suction part is chewed and is with flexible plastic cement sucker 8 on 6.Said vaccum suction pipe 4 connects the vavuum pump (not shown) through solenoid vacuum valve and negative pressure chamber.During the die sinking pickup; Robot actions pickup plate makes fixed head 3 press close to moulding, and solenoid vacuum valve is opened; Chewing suction part that through hole 7 exposes by the suction part on the fixed head 3 chews 6 and connects negative pressure chamber through grooved passage 5, vaccum suction pipe 4 and forms negative pressure, the moulding of absorption moulding.
Because shaping mould temperature higher (125-130 ℃), to cool off when insufficient, product cast gate place is prone to produce the pull-up phenomenon, needs usually and will extend to cool time more than 60 seconds.Prolong cool time, the heat time heating time of the front mold of part injection mo(u)lding next time also corresponding lengthening, not only production efficiency reduces, and also increases energy consumption simultaneously.
