Description

Technical Field

[0001] This application relates to the feeding technology of injection molding machines, and specifically relates to a feeding device for an injection molding machine. Background Art

[0002] When using an injection molding machine to process plastic products such as refrigerator drawers, generally, a special-shaped closed space is formed by the cooperation of a female mold and a male mold, and injection molding is carried out into this closed space through the injection port on the female mold. After injection molding and cooling and forming, the male mold is withdrawn from the female mold, and the formed plastic product adheres to the male mold. Finally, the plastic product is ejected by the ejector rod on the male mold, and thus the processing of the plastic product is completed.

[0003] Currently, after a general injection molding machine ejects a plastic product, the plastic product directly falls from the male mold and lands on the receiving point. This feeding method is likely to cause bumps to the plastic product, resulting in its damage; at the same time, due to the limited space below the male mold, after a certain number of plastic products have fallen, it is necessary to manually collect the fallen plastic products and perform subsequent processes such as quality inspection on them, which is rather troublesome. Utility Model Content

[0004] To solve the above-mentioned defects in the related prior art, this application provides a feeding device for an injection molding machine, which can avoid bumps during the feeding of plastic products and can continuously feed materials, and has strong practicability.

[0005] To achieve the above purpose, the present utility model adopts the following technologies:

[0006] A feeding device for an injection molding machine, comprising:

[0007] A bottom plate;

[0008] A feeding mechanism, including a suction cup, a vacuum chamber, a mounting plate, and a moving plate. The axis of the suction cup is parallel to the length direction of the bottom plate, and one end thereof is arranged on the vacuum chamber and communicated with the vacuum chamber. The air pressure in the vacuum chamber is adjustable. The vacuum chamber is rotatably connected to one side surface of the mounting plate, and its rotation axis is parallel to the length direction of the bottom plate. The moving plate is spaced and connected to the other side surface of the mounting plate and the spacing is adjustable. The moving plate is arranged to move along the height direction and the width direction of the bottom plate;

[0009] A conveyor belt, which is spaced above the bottom plate and arranged along the length direction of the bottom plate.

[0010] Further, a linear cylinder is arranged on the moving plate along the length direction of the bottom plate, and the driving shaft of the linear cylinder is connected to the other side surface of the mounting plate.

[0011] Further, a vacuum machine is arranged on the moving plate. The vacuum machine is communicated with a vacuum tube, and the vacuum tube is communicated to the vacuum chamber.

[0012] Further, a rotating motor is provided on the mounting plate along the length direction of the bottom plate, and the driving shaft of the rotating motor is connected to the vacuum chamber.

[0013] Further, a first electric screw rod is provided on the bottom plate along its width direction. The first electric screw rod is engaged with a first mating block. A second electric screw rod is provided on the first mating block along the height direction of the bottom plate. The second electric screw rod is engaged with a second mating block, and the second mating block is connected to the moving plate.

[0014] The beneficial effects of the present utility model are as follows:

[0015] The formed plastic products are removed from the punch by the blanking mechanism, and the plastic products will not be bumped during the blanking process. At the same time, the plastic products are flipped and laid flat on the conveyor belt by the blanking mechanism, and the conveyor belt immediately transports them to the next process, enabling the blanking mechanism to continuously blank the formed plastic products and improving the blanking efficiency.

Detailed Embodiments

[0019] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the following describes the embodiments of the present utility model in detail with reference to the drawings. However, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0020] As Figure 1 shown, this embodiment provides an injection molding machine blanking device, including a bottom plate 1, a blanking mechanism 2, and a conveyor belt 3.

[0021] Specifically, as Figure 1 shown, the bottom plate 1 is in the shape of a rectangular plate.

[0022] Specifically, as Figure 1 and Figure 2As shown in the figure, the blanking mechanism 2 includes suction cups 21, a vacuum chamber 22, a mounting plate 23, and a moving plate 24. There are two suction cups 21, and their axes are all parallel to the length direction of the bottom plate 1. One end of each suction cup is provided on the vacuum chamber 22 and communicates with one side surface of the vacuum chamber 22. More specifically, the adsorption surfaces of the two suction cups 21 are coplanar and parallel to the end surface of the bottom plate 1. The suction cups 21 are used to adsorb plastic products; the air pressure in the vacuum chamber 22 is adjustable. The other side surface of the vacuum chamber 22 is rotatably connected to one side surface of the mounting plate 23, and its rotation axis is parallel to the length direction of the bottom plate 1. The other side surface of the mounting plate 23 is connected to the moving plate 24 at intervals and the distance is adjustable. The moving plate 24 is movably arranged along the height direction and the width direction of the bottom plate 1, and is used to drive the suction cups 21 to move along the width direction and the height direction of the bottom plate 1 through the mounting plate 23 and the vacuum chamber 22.

[0023] Specifically, as Figure 1 shown, the conveyor belt 3 is arranged at intervals above the bottom plate 1 and is arranged along the length direction of the bottom plate 1. The conveyor belt 3 is used to convey plastic products.

[0025] Move the male mold 41 to make the male mold 41 cooperate with the female mold 42 to form a special-shaped closed space, and inject plastic into this closed space through the injection port on the female mold 42. After the injection is completed and cooled and formed, withdraw the male mold 41 from the female mold 42, and the formed plastic product adheres to the male mold 41.

[0026] Move the moving plate 24 and adjust the distance between the mounting plate 23 and the moving plate 24 so that the adsorption surface of the suction cup 21 closely adheres to one side of the plastic product attached to the male mold. Reduce the air pressure in the vacuum chamber 22 so that the suction cup 21 tightly adsorbs the plastic product; move the moving plate 24 along the width direction of the bottom plate 1 to make the plastic product separate from the male mold 41, and move the moving plate 24 downward along the height direction of the bottom plate 1 to make the plastic product withdraw from between the male mold 41 and the female mold 42. At this time, the next injection can be carried out; rotate the vacuum chamber 22 to make the plastic product at an angle where it can be stably placed on the conveyor belt 3, move the moving plate 24 and increase the air pressure in the vacuum chamber 22, and stably place the plastic product on the conveying surface of the conveyor belt 3. The conveyor belt 3 conveys the plastic product to the next process, and at this time, the blanking of the next formed plastic product can be carried out.
