The invention discloses a switch control device. The switch control device comprises a shell, wherein a positioning device is arranged on the shell; a pushing structure used for pushing a switch to be switched on and off is arranged on one side of the shell; the pushing structure comprises two sliding slots which are formed in the shell; openings are formed in one side of each of the two sliding slots; flanges are arranged at the opening ends of the sliding slots; springs propped against the flanges are arranged at the interiors of the sliding slots; a sliding block is arranged at the other end of each spring in a propping manner; ejection rods are arranged on the sliding blocks in the direction facing towards the openings of the sliding slots; magnets are arranged on the sliding blocks; electromagnets are arranged at the closed ends of the sliding slots and are sequentially connected with a delayer, a power supply and a shifting switch; when the electromagnets are electrified, the electromagnets and the magnets mutually repel; the shifting switch is arranged on the other side of the shell; the shell is mounted on the switch; the shifting switch is switched off by the switch after the switch is pushed by the pushing structure. Through the adoption of the device, the problem that a person goes to bed in the dark after switching off the switch under the condition that the position of the switch is far from the bed can be solved.

The invention relates to the technical field of injection molding equipment, in particular to an injection molding manipulator and an injection molding method. The injection molding manipulator comprises a manipulator, a material bearing frame, a shifting mechanism, a material inspection worktable, a defective product device box, a shifting support frame, a shifting plate, a detection sensor, an error-proof detection shaft, a shifting cylinder, a part taking and placing device, a material taking device, an auxiliary parting device and a control device. The control device controls the shiftingmechanism to move a part to a position where the manipulator can grasp the part; then the part is moved toward a mold by the manipulator, and the material taking device takes out an injection molded finished product from the mold; then the part is implanted into the mold through the part taking and placing device; after that, defective products judged by an injection molding machine are put into the defective product box through the manipulator; and the injection molded finished product is placed on the worktable to be further inspected along a feeding belt by the material taking device. In this way, a complete set of smooth and quick operations of a product with parts placed in a mold for injection molding together can be achieved, so that the working efficiency is effectively improved.
