Technical Field

[0001] The utility model relates to the technical field of injection molding, in particular to a piece taking device for injection molding of a water purifier shell. Background Art

[0002] A water dispenser is a device that heats or cools bottled pure water (or mineral water) to make it convenient for people to drink. Its shell is usually produced by injection molding.

[0003] At present, when the water dispenser shell is produced by the injection molding process, its surface is usually non-planar and has many concave or convex areas. When the commonly used fixed vacuum suction cup is used to remove the part from the inside of the injection mold, the vacuum suction cup cannot make good contact with the surface of the shell, so it is not possible to remove the part well. For this reason, we propose a removal device for injection molding of water purifier shell. Utility Model Content

[0004] The purpose of the utility model is to provide a device for removing parts for injection molding of water purifier shell, which has the advantage that when removing parts through the vacuum suction cup, the telescopic vacuum suction cup can better contact the surface of the water dispenser shell to facilitate the removal of parts, and solves the problem that when the current water dispenser shell is produced through the injection molding process, the surface is usually non-planar and has more concave or convex areas. When the commonly used fixed vacuum suction cup is used to remove parts from the inside of the injection mold, the vacuum suction cup cannot achieve good contact with the surface of the shell, so the part cannot be removed well.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a device for removing parts for injection molding of water purifier housing, comprising a connecting pipe, an oil storage pipe and a vacuum suction cup, wherein an oil storage pipe is fixedly installed on one side of the outer surface of the connecting pipe, a connecting valve is fixedly connected to the lower surface of the oil storage pipe, and the end of the connecting valve is fixedly connected to the outer surface of the connecting pipe, a plurality of sleeves are fixedly connected to the side of the outer surface of the connecting pipe away from the oil storage pipe, a movable spring is fixedly connected to the inside of each sleeve, a movable piston is fixedly connected to the end of each movable spring, a sliding rod is fixedly connected to the outer surface of each movable piston, and a vacuum suction cup is fixedly connected to the end of the sliding rod located outside the sleeve.

[0006] Preferably, the upper surface of the oil storage pipe is provided with communicating air holes.

[0007] Preferably, a dust filter is fixedly installed inside the communicating air hole.

[0008] Preferably, a fixing plate is fixedly mounted on one side of the outer surface of the connecting pipe close to the oil storage pipe.

[0011] Preferably, an automatic exhaust valve is fixedly connected to the upper surface of the pressing piston.

[0012] Preferably, an oil change valve is fixedly connected to the outer surface of the connecting pipe near the lower surface.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The utility model achieves the effect that when taking out the parts through the vacuum suction cup, the telescopic vacuum suction cup can better contact the surface of the water dispenser shell to facilitate the taking out of the parts by arranging a connecting pipe, an oil storage pipe, a connecting valve, a sleeve, a movable spring, a movable piston, a sliding rod and a vacuum suction cup. The connecting pipe is fixed on the mechanical arm. When taking out the parts, the mechanical arm drives the device to move so that the vacuum suction cup contacts the surface of the water dispenser shell inside the injection mold. Due to the elastic effect of the movable spring and the sliding rod that can slide inside the sleeve, the vacuum suction cup can extend into the recessed area of ​​the water dispenser shell and can also contact the raised part of the water dispenser shell. During the movement of the sliding rod, the oil in the oil storage pipe enters into the connecting pipe or the oil inside the connecting pipe enters into the oil storage pipe. After the vacuum suction cup is adsorbed on the surface of the water dispenser shell, the connecting valve is closed, and the mechanical arm drives the device to move, so that the water dispenser shell can be taken out from the injection mold.

[0015] 2. The utility model provides a dustproof filter to filter the air entering the oil storage pipe, thereby preventing dust and impurities from entering the oil storage pipe.

[0016] 3. The utility model is conducive to exhausting the air in the oil through the downward pressure spring, the downward pressure piston and the automatic exhaust valve. The elastic force of the downward pressure spring causes the downward pressure piston to be pressed downward, and the air in the oil is exhausted through the automatic exhaust valve.
