Problems solved by technology

[0006] The object of the present invention is to overcome the problems existing in the existing thin and small injection molded parts mold opening and cooling method and the pick-up plate, and provide a new type of thin and small injection molded parts mold opening and cooling method. The technical problem to be solved is that the mold temperature Under the premise of basically no reduction, the gate position where the parts are easily deformed is locally cooled, so as to eliminate the problem that the gate is prone to pull-up phenomenon,

Embodiment 1

[0040] see Figure 4 , Figure 5 , Figure 6 and Figure 8 According to the present invention, a pick-up plate 100 for the above-mentioned method of opening and cooling thin injection molded parts includes a channel plate 120 with a vacuum suction tube 110 and a grooved channel 121 that is sequentially pasted and assembled, and is provided with a communication channel. The vacuum suction plate 140 of the suction piece nozzle 130 of the grooved channel 121 and the fixed plate 160 provided with the suction piece nozzle through hole 161, the suction piece nozzle 130 is covered with a flexible plastic suction cup 170, the above structure is the existing pick-up plate structure; the invention point of the present invention is to recombine the device for spraying cold air to the connection position of the injection molded part and the gate with the pick-up plate, and the manipulator can complete the work of local air cooling and pick-up in one action, which not only reduces the ma...

Embodiment 2

[0043] Figure 7 Shown is another embodiment of the pick-up plate of the present invention. The pick-up plate 200 of this embodiment also includes a channel plate 220 that is sequentially fitted and assembled with a vacuum suction tube 210 and a grooved channel 221, and is provided with a communicating groove. The vacuum suction plate 240 of the suction part of the type channel 221 and the fixed plate 260 that is provided with the through hole 261 of the suction part. The connection position of the nozzle is provided with a nozzle hole 262; the position corresponding to the nozzle hole 262 on the vacuum suction plate 240 is provided with an air chamber 241 through the plate thickness containing the nozzle hole 262; The through hole 222 of the air chamber 241 of the plate 240 is also provided with an air pipe joint 223 on the through hole 222 of the channel plate 220 .

[0044] The difference between this embodiment and the first embodiment is that the slot-shaped air chamber ...

Abstract

The invention relates to the injection molding process technology of injection molding parts, in particular to a method for mold-unloading and cooling a thin and small injection molding part and a part taking board thereof. The method comprises the following steps of: adding a local air cooling structure to the part taking board, cooling a mold with water to a mold-unloading temperature before unloading the mold and taking the part, and locally cooling the joint of the part and the sprue of the injection molding part after unloading the mold before sucking up in vacuum. Therefore, the problem that the sprue of the product is easily drawn out when the thin and small injection molding part is sucked up in vacuum is solved. Because of the little temperature drop of the mold, the invention greatly improves the production efficiency of the equipment, saves the energy, reduces the cost and increases the economic benefit.

Description

technical field [0001] The invention relates to an injection molding processing technology for injection molded parts, in particular to a mold opening and cooling method for thin and small injection molded parts and a pick-up plate. Background technique [0002] A mobile phone button, made of transparent PC material, its thickness is about 1mm, it is molded by injection molding of multiple parts in one mold, and the injection molded parts after molding are as follows: figure 1 As shown, it includes a button 10 and a sprue 20 connecting the button 10 . The injection molding process is as follows: (1) mold closing; (2) heating to heat the mold to reach the molding temperature; (3) injection; (4) cooling to cool the mold to reach the mold opening temperature; (5) Open the mold and pick up the parts. The mold opening is picked up by a manipulator through a vacuum pick-up plate, and the pick-up plate is as figure 2 , image 3 As shown, the channel plate 1, the vacuum suction...
