Description

Technical Field

[0001] The utility model relates to an automatic feeding injection molding machine. Background Art

[0002] Vertical injection molding machine is a kind of equipment used for plastic processing, mainly used to manufacture plastic products. Its working principle is to heat plastic particles and inject them into the mold, and then cool and solidify under high pressure to finally form the desired plastic products. Compared with other types of injection molding machines, vertical injection molding machines usually occupy a smaller area and are suitable for vertical operation.

[0003] In existing vertical injection molding machines, plastic particles are usually fed into the syringe, melted into plastic fluid under the action of a heating device, and then fed into the mold under the pressure of an injection rod. However, the existing input method is usually manual input, which is inefficient and has high labor costs. There are also automatic feeding methods using a robot with a corresponding CNC device, but this will result in higher manufacturing costs. Utility Model Content

[0021] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0022] In the description of the present utility model, "multiple" means two or more than two, unless otherwise clearly specified and specifically defined. In the present utility model, unless otherwise clearly specified and defined, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal connection of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0023] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0024] like Figure 1 As shown, an automatic feeding injection molding machine includes a frame 1. A mold 2 is arranged at the bottom of the frame 1, and an injection cylinder 3 is arranged above the middle of the mold 2. The injection cylinder 3 is connected to the feed port of the mold 2. An injection rod 4 is arranged above the injection cylinder 3, and the injection rod 4 is connected to a cylinder 5 at the top of the frame 1. When the cylinder 5 is working, it can drive the injection rod 4 to move up and down, so that the plastic fluid in the injection cylinder 3, which is melted by the heating device, is input into the mold 2 for product molding.

[0025] like Figure 2 , Figure 3 , Figure 4 As shown, correspondingly, a driving block 6 is provided in the middle of the injection rod 4. A ratchet 7 is provided on one side of the driving block 6. The ratchet 7 is hinged with the driving block 6 and a torsion spring 8 is provided at the hinge. Correspondingly, a limit plate 9 is provided below the ratchet 7 to prevent the ratchet 7 from swinging downward (rotating clockwise).

[0026] A ratchet 10 is correspondingly arranged on one side of the pawl 7. The ratchet 10 is connected to a driving shaft 11. The driving shaft 11 is connected to the frame 1 by a bearing. A gear 12 is connected to one side of the driving shaft 11. The gear 12 is meshed with a gear 2 13. The gear 2 13 is connected to a rotating shaft 14. The rotating shaft 14 is connected to a conveyor belt 15. A plurality of baffles 16 are arranged on the conveyor belt 15, and a conveying trough 17 is formed between the baffles 16. Correspondingly, the conveyor belt 15 is arranged obliquely, and a storage box 18 is correspondingly arranged at the bottom of the conveyor belt 15. When the conveyor belt 15 is working, the baffle 16 can input the plastic particles in the storage box 18 into the conveying trough 17, and after the movement of the conveyor belt 15, it finally reaches the top of the conveyor belt 15 and flips over.

[0027] Correspondingly, a guide frame 19 is provided on one side of the top of the conveyor belt 15. The guide frame 19 is provided between the injection barrel 3 and the conveyor belt 15. When the plastic particles in the conveyor belt 15 are turned over, they enter the guide frame 19 and enter the injection barrel 3 through the guide frame 19, completing the automatic feeding process.

[0028] Overall working process:

[0029] 1. When the injection rod 4 moves upward under the action of the cylinder 5, the driving block 6 moves upward, so that the pawl 7 moves upward and drives the ratchet 10 to rotate under the action of the limit plate 9. The rotation of the ratchet 10 drives the gear 12 to rotate, and then drives the gear 2 13 to rotate. The gear 2 13 drives the rotating shaft 14 to rotate, so that the conveyor belt 15 moves to the position of the conveying groove 17;

[0030] 2. The plastic particles in the conveying trough 17 at the top are turned over and enter the guide frame 19, and are melted by the heating device of the injection cylinder 3 to form a plastic fluid;

[0031] 3. The injection rod 4 moves downward under the action of the cylinder 5. At this time, the pawl 7 rotates counterclockwise, which will not drive the ratchet wheel 10 to rotate, and the conveyor belt 15 does not work;

[0032] 4. The injection rod 4 inputs the plastic fluid into the mold 2 to form the product;

[0033] 5. Repeat steps 1-4 to achieve the technical purpose of automatic feeding.

[0034] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
