Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of injection molding machines, in particular to a material unloading auxiliary device for a plastic injection molding machine. Background Art
[0002] Plastic parts are generally directly molded by injection molding machines. Injection molding machines, also known as injection molding machines or injection machines, are the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics.
[0003] After the injection molding of the plastic parts is completed, the automatic demoulding mechanism inside the injection molding machine will eject the molded plastic parts outwards, and the ejected plastic parts will fall into the collection box. The operator is required to place the collection box under the discharge port of the injection molding machine in advance. After the plastic parts have finished falling, the operator is required to take the collection box out from under the discharge port of the injection molding machine. It is inconvenient to take and place, and the temperature of the discharge port of the injection molding machine is relatively high. It is very easy for the operator to cause collision damage when taking and placing the collection box, and the labor intensity is high. Summary of the invention

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:
[0006] A material unloading auxiliary device for a plastic parts injection molding machine comprises a base plate and a conveyor belt bracket, a conveyor belt is installed on the conveyor belt bracket, the base plate is fixedly installed on the ground, two columns are fixedly installed on the base plate, fixed blocks are fixedly installed opposite the two columns, nut blocks are embedded in the fixed blocks, screws are arranged below both sides of the conveyor belt bracket, both ends of the screws are connected to the conveyor belt bracket through bearing seats, the screws and the nut blocks are connected by threads, servo motors are fixedly installed downward on both sides of the conveyor belt bracket, the output shaft of the servo motor is fixedly connected to the end of the screw, and a collecting box with an upper opening is placed on the base plate.
[0007] In this way, by fixing the base plate on the ground, the device can be stably installed to avoid overturning. During the unloading process, the servo motor drives the screw to rotate, and the nut block and the screw cooperate to drive the conveyor belt bracket to move, and the conveyor belt moves to the bottom of the unloading port. The injection molding machine unloads the material onto the conveyor belt, and the conveyor belt drives the plastic parts to move to the collection box on the base plate. Then, the servo motor drives the screw to rotate in the opposite direction, so that the conveyor belt bracket moves to the top of the base plate, and the conveyor belt is detached from the bottom of the unloading port of the injection molding machine, completing the unloading process.
[0008] Wherein, a collecting hopper is fixedly installed on the conveyor belt bracket, and the upper end opening size of the collecting hopper is larger than the lower end opening size.
[0009] Wherein, guide plates are fixedly installed on both sides of the conveyor belt bracket, and one end of the guide plate away from the collecting hopper is bent and extended inwardly, and the two guide plates are arranged at intervals.
[0010] Among them, guide rods are arranged on both sides of the base plate, one end of the guide rod is fixedly connected to the column, and the other end of the guide rod is fixedly connected to the base plate through the vertical plate. Guide plates are fixedly installed downward on both sides of the conveyor belt bracket, and the guide plates are provided with guide holes that slide with the guide rods.
[0011] Wherein, rib plates are fixed on both sides of the conveyor belt bracket and the guide plate.
[0012] In summary, the material unloading auxiliary device for the plastic injection molding machine has the advantages of being able to automatically collect plastic parts, being easy to use, and being highly safe. BRIEF DESCRIPTION OF THE DRAWINGS
