Description

Technical Field

[0001] The utility model relates to the technical field of injection molding machines, in particular to a feed opening of an injection molding machine feeder and the injection molding machine feeder. Background Art

[0002] The function of the feeder used in the injection molding machine is to feed the material. Its working principle is to use vacuum to input the granular material into the feeder so that it can be used by the injection molding machine. Figure 1 and Figure 2 As shown in the figure, it is a structural schematic diagram of the current injection molding machine feeder. In actual use, the granular material is input into the silo 1 through the feed port, and the discharge port 2 is installed at the bottom of the silo. A gravity baffle is arranged at the bottom of the discharge port 2. When there is granular material in the silo, it will flow out from the discharge port due to gravity. When the granular material in the silo 1 is discharged, the gravity baffle 3 is reset and abuts against the discharge port, thereby forming a vacuum environment in the silo 1, so as to suck the granular material into the silo again. In actual use, the structure of the discharge port 2 is as shown in FIG. Figure 3 As shown, there is a partial slope on one side of the contact position with the gravity baffle 3, so that there is a gap between the outer edge of the discharge port and the gravity baffle, so that when a vacuum is formed in the silo 1, some granular materials are accumulated on the slope. When a negative pressure process is formed in the silo, these granular materials can easily pass through the discharge port 2 from the slope and be clamped between the discharge port 2 and the gravity baffle 3, thereby affecting the sealing, making it difficult for the silo 1 to form a vacuum, and thus failing to load materials normally.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] like Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, the injection molding machine loader in this embodiment includes a silo 1 and a discharge port 2 of the injection molding machine loader. The discharge port 2 is arranged at the bottom of the silo 1. A gravity baffle 3 for sealing or opening the discharge port 2 is also arranged in the silo 1.

[0024] like Figure 4 As shown, the feed port 2 of the injection molding machine feeder includes a flange 21 and a barrel 22. The flange 21 is used to connect with the silo 1, and is provided with a mounting hole 211 for connecting with the silo 1, so as to facilitate fixing the feed port 2 on the silo 1 by fasteners such as bolts.

[0025] In some embodiments, the upper end of the cylinder 22 and the flange 21 may be integrally formed to increase structural strength and simplify the manufacturing process.

[0026] like Figure 4 - Figure 6 As shown, the lower end of the cylinder 22 is provided with an abutting slope 221 for cooperating with the gravity baffle 3. The outer edge of the abutting slope 221 is provided with a sealing portion 222, which is used to closely abut the gravity baffle 3 to prevent the granules from closely abutting the outer edge of the gravity baffle 3 and the abutting slope, that is, the outer edge of the discharge port 2, thereby preventing the granules from accumulating here, and the inner side of the abutting slope 221 is provided with a slope 223, which can further guide the granules from the outer side of the discharge port 2 to the inner side of the discharge port 2, thereby preventing the granules from being sandwiched between the discharge port 2 and the gravity baffle 3, thereby causing air leakage and affecting the feeding effect.

[0027] In some embodiments, the slope 223 can be designed in two forms: one is a straight line (not shown in the figure), and the other is an arc (such as Figure 6 As shown in FIG. 2 , whether it is a straight line or an arc, the slope 223 starts from the outer edge of the abutting inclined surface 221, gradually rises to the inner edge, and forms a sealing portion 222 at the lower end of the slope 223. Such a design ensures that the pellets are blocked between the feed port and the gravity baffle, and also ensures a tight fit between the sealing portion 222 and the gravity baffle 3.

[0028] like Figure 1 As shown, a material discharge sensor 4 is provided on the silo 1 to detect whether material is discharged from the discharge port 2. When the material discharge sensor 4 detects that no material is discharged from the discharge port 2, a signal can be sent to the control system, and the control system further controls the vacuum pump and other equipment to realize automatic feeding.

[0029] Through the above design, the injection molding machine feeder of the utility model can effectively prevent the granular material from being blocked between the discharge port and the gravity baffle, ensuring that a vacuum environment can be smoothly formed in the silo 1, thereby improving the feeding efficiency and stability.

[0030] Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field belong to the protection scope of the utility model.
