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 made by transparent PC material, and the about 1mm of its thickness adopts the one-mold multiple-member injection mo(u)lding, the moulding after the moulding as shown in Figure 1, it comprises button 10 and the running channel 20 that is connected button 10.Its Shooting Technique is as follows: (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.Described die sinking pickup adopts manipulator to draw by vacuum pickup plate, described pickup plate such as Fig. 2, shown in Figure 3, by channel plate 1, vacuum suction disc 2 and fixed head 3 are fitted in regular turn and are assembled, the lateral surface of described channel plate 1 is provided with vaccum suction pipe 4, the another side of fitting with described vacuum suction disc 2 is provided with the grooved passage 5 that is communicated with vaccum suction pipe 4, described vacuum suction disc 2 is provided with the suction part that is communicated with described grooved passage 5 with described fixed head 3 binding faces and chews 6, described fixed head 3 is provided with for described suction part and chews the 6 suction parts that wear and chew through hole 7, and described suction part is chewed and is with flexible plastic cement sucker 8 on 6.Described vaccum suction pipe 4 connects the vavuum pump (not shown) by 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 by 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 easily produces 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.
This shows that obviously still there is deficiency in above-mentioned existing thin little moulding, and demands urgently further being improved on die sinking cooling pickup method.In order to solve thin little moulding in the existing problem of die sinking pickup, relevant manufacturer there's no one who doesn't or isn't seeks solution painstakingly, but do not see always that for a long time suitable construction method is done, therefore how to found a kind of making and approach the rapid cooling of little moulding and little thin little moulding method for mold-unloading and cooling and the pickup plate of mould cooling, the problem that the current industry utmost point of real genus need solve.
Because the defective that exists on the above-mentioned existing thin little moulding die sinking cooling pickup method, the design people is based on being engaged in this type of product design manufacturing abundant for many years practical experience and professional knowledge, and the utilization of cooperation scientific principle, actively studied innovation, in the hope of founding a kind of novel thin little moulding method for mold-unloading and cooling and pickup plate, make it have more practicality.Through constantly research, design, and after studying sample and improvement repeatedly, create the present invention who has practical value finally.
