[0001] The application relates to the technical field of injection molding machines, in particular to an automatic feeding and discharging device of an injection molding machine. BACKGROUND

[0002] The injection molding machine is also called an injection molding machine or an injection molding machine, and is main molding equipment for making various plastic products from thermoplastic or thermosetting plastics by using a plastic molding die. When the injection molding machine is used, an automatic feeding and discharging device needs to be used to automatically feed and discharge the injection molding machine.

In addition, the feeding and discharging device stops working during the injection molding process of the injection molding machine, which leads to low working efficiency and inconvenient use. Therefore, the application provides an automatic feeding and discharging device of an injection molding machine to solve the above problems. SUMMARY

The spiral conveyor is connected with a feeding hose on the outer side close to the lower side, the spiral conveyor is connected with a discharging pipe on one side close to the upper end, a worm gear is installed at the rotating shaft end of the spiral conveyor, a worm is rotatably connected to the side of the support close to the worm gear, and the spiral conveyor is automatically turned over by the turning-over mechanism when the sliding seat slides to the injection molding mechanism.

[0006] Preferably, the injection mechanism comprises a fixed mold, the fixed mold is symmetrically arranged on the top of the base on both sides, a movable mold is arranged on the side close to the fixed mold of the fixed frame, the fixed frame is connected with the movable mold through the hydraulic telescopic rod, a heating cylinder is arranged on the top of the base close to the outside of the fixed mold, and a feeding hopper is communicated with the top of the heating cylinder away from the fixed mold.

[0007] Preferably, the driving mechanism comprises a sliding groove, the sliding groove is arranged on the top of the base corresponding to the sliding seat, the sliding seat is fixedly connected with a sliding block at the bottom corresponding to the sliding groove, a lead screw is rotatably connected in the sliding groove, and a motor is arranged on one end of the base corresponding to the sliding groove.

[0008] Preferably, the sliding groove is arranged in parallel with the long side of the base, the internal size of the sliding groove is consistent with the external size of the sliding block, and the sliding block and the lead screw are in threaded connection.

[0009] Preferably, the tooth pitch of the worm wheel is equal to the tooth pitch of the worm, and the worm wheel is engaged with the worm.

[0010] Preferably, the turnover mechanism comprises a rotating shaft, the rotating shaft is rotatably connected to the top of the sliding seat close to the worm, the bottom end of the worm is fixedly connected with a first reversing gear, the rotating shaft is fixedly connected with a second reversing gear on the outside corresponding to the first reversing gear, one end of the rotating shaft is fixedly connected with a first gear, the first rack is fixedly connected to the top of one end of the base corresponding to the first gear, the second end of the rotating shaft is fixedly connected with a second gear, the third gear engaged with the second gear is rotatably connected to the top of the sliding seat close to the second gear, and the second rack is fixedly connected to the top of the other end of the base corresponding to the third gear.

[0011] Preferably, the first reversing gear and the second reversing gear are perpendicular to each other and engaged with each other.

[0012] Preferably, the tooth pitch of the first gear and the first rack is equal, and the tooth pitch of the third gear and the second rack is equal.

[0013] Preferably, the first rack and the second rack are respectively arranged at the two injection mechanisms, and the second rack is arranged in a staggered manner with the second gear.

[0014] Compared with the prior art, the beneficial effects of the present application are as follows: This invention, by setting up two sets of injection molding mechanisms and driving a sliding seat on both sides to move between the two sets of injection molding mechanisms, allows the other set of injection molding mechanisms to open while one set of injection molding mechanisms is closing the mold and performing injection molding. The sliding seats on both sides simultaneously drive the robotic arm and the screw conveyor to the set of injection molding mechanisms that have opened the mold. The robotic arm picks up the material through the unloading execution end and places it on the conveyor belt. At the same time, the screw conveyor moves to the heating cylinder and transports the raw material to the feeding hopper through the discharge pipe. This allows for the loading and unloading of the material for the set of injection molding mechanisms that have opened the mold. After the mold is closed and injection molding is performed, the loading and unloading equipment moves to the other set of injection molding mechanisms. By setting up two sets of injection molding mechanisms and a sliding loading and unloading equipment, the loading and unloading equipment can simultaneously load and unload materials for both sets of injection molding mechanisms. This not only effectively reduces the number of equipment and lowers production costs, but also effectively improves the working efficiency of the loading and unloading equipment.

[0015] In this invention, when the sliding seat drives the screw conveyor to move toward a set of injection molding mechanisms, the first gear meshes with the first rack. The movement of the sliding seat causes the first gear to drive the rotating shaft to rotate. The rotating shaft, through the second and first reversing gears, drives the worm to rotate. The worm, through meshing, drives the worm wheel to rotate, thereby causing the screw conveyor to rotate from its vertical position toward the heating cylinder, aligning the screw conveyor's discharge pipe with the feed hopper for feeding. When the sliding seat moves in the opposite direction, the meshing of the first gear and the first rack causes the screw conveyor to rotate in the vertical direction. When the sliding seat drives the screw conveyor to move toward another set of injection molding mechanisms, the first gear meshes with the first rack, causing the screw conveyor to rotate in the vertical direction. The second rack drives the third gear to rotate through meshing, and the third gear drives the second gear to rotate through meshing, causing the second gear to rotate the shaft. This, in turn, causes the screw conveyor to rotate from its vertical position towards the heating cylinder. When the sliding seat moves in the opposite direction, it also drives the screw conveyor to rotate in the vertical direction. Through the set flipping mechanism, when the sliding seat drives the screw conveyor to move between the two injection molding mechanisms, the screw conveyor can automatically flip, avoiding collisions with the injection molding mechanism during movement. At the same time, when the screw conveyor moves to the designated position, the screw conveyor's discharge pipe is aligned with the feed hopper for feeding. Attached Figure Description
