The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-2, the present invention provides a technical solution: the utility model provides a discharging device for injection molding machine, includes casing 1, and last feedway 2 is installed to casing 1's inner chamber upper end, and pressure device 3 is installed to casing 1's inner chamber lower extreme, and casing 1's tail end fixed mounting has support frame 4, and support frame 4's tail end fixed mounting has connecting seat 5, and casing 1's front end spiro union has runner to connect mouth 6.
In the device, the motor 27, the infrared sensor 7 and the hydraulic rod 33 are controlled by an external terminal, and the hydraulic rod 33 is connected with an external hydraulic pump.
And the gate connector 6 is used to align the gate utility while the connector base 5 is used to connect the injection molding machine.
Specifically, the continuous feeding device 2 comprises two first piston holes 21 which are arranged at the upper part of the shell 1 and distributed in parallel, a piston 22 is sleeved in the first piston hole 21, a screw 23 is fixedly arranged at the tail end of the piston 22, the rotating directions of the two lead screws 23 are opposite, the tail end of the shell 1 is fixedly provided with a mounting box 24 at the first piston hole 21, the lower end of the inner cavity of the mounting box 24 is rotatably provided with two first gears 25, and the middle part of the first gear 25 is connected with the screw 23 in a threaded manner, the upper end of the inner cavity of the mounting box 24 is rotatably provided with a second gear 26 engaged with the two first gears 25, the wheel axle of the second gear 26 is fixedly provided with a motor 27 fixedly arranged with the support 4, the head end of the first piston hole 21 is fixedly provided with a feed pipe 28, the inner cavity of the feed pipe 28 is fixedly provided with a first single valve 29, and the tail end of the screw is fixedly provided with a square limit block.
In operation, the two pistons 22 can be driven to move relatively (one piston moves outwards and the other piston moves inwards) through the action of the positive and negative rotation of the motor 27 and the action of the two screw rods 23 with opposite screw directions, when the pistons move inwards, the first single-item valve 29 is closed, the second single-item valve 35 is opened, raw materials in the first piston hole 21 enter the second piston hole 31, when the pistons move outwards, the first single-item valve 29 is opened, the second single-item valve 35 is closed, the raw materials can enter the first piston hole 21 from the feeding pipe 38, and therefore continuous feeding is achieved.
After the use, when the feeding pipe 28 has no raw material, the two pistons 22 are repeatedly operated once, so that the raw material in the first piston hole 21 can be extruded into the second piston hole 31, and secondary cleaning is not needed.
