Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] See also Figure 1-6 The utility model provides a technical solution: a powder molding press equipped with a weighing feeding structure, including a bracket 1, a material box 1 2, a material box 2 3, a feed port 4, a discharge port 5, a valve 6, a weight sensor 7, a powder pump 8, a material tray 9, a clamping block 10, a limit block 11, a baffle 12, a cylinder 13, a collecting box 14, a cylinder 2 15, and a pressing plate 16.

[0031] Example 1

[0032] The powder forming press is provided with a weighing and unloading structure, which can control the amount of unloading so that each trough of the material tray 9 is evenly filled with material. Specifically:

[0033] The upper surface of the bracket 1 is provided with an opening, and also includes a material box 1 2. The weighing and unloading structure includes a material box 2 3. The upper surface of the material box 2 3 is penetrated and installed with a feed port 4. The material box 2 3 is installed on the upper surface of the material box 1 2. The lower surface of the material box 2 3 is provided with a unloading port and is connected to the upper surface of the material box 2 3. A valve 6 is installed on the outer surface of the unloading port. A partition is fixedly installed on the inner wall surface of the material box 1 2. A weight sensor 7 is installed on the upper surface of the partition. The weight sensor 7 controls the connection There is a valve 6, a powder pump 8 is installed below the weight sensor 7, and the powder pump 8 is installed on the bottom surface of the inner wall of the material box 1 2. The other side of the powder pump 8 is connected to the discharge port 5, and the material tray 9 is correspondingly provided below the discharge port 5. The material box 1 2 is installed on the upper surface of the bracket 1, and the bracket 1 is connected to a weighing and unloading structure. The weighing and unloading structure can control the amount of material unloaded from the material box 2 3 through the weight sensor 7 in the material box 1 2. The material box 2 3 is set as an n-shaped structure, and there are 3 discharge ports 5;

[0034] When the powder forming press is used, first, Figure 2 As shown, the powder material is added into the material box 2 3 from the feed port 4 on the upper surface of the material box 2 3, as shown in FIG. Figure 4 As shown, after the material enters the material box 2 3, the valve 6 on the outer surface of the discharge port, which is connected to the lower surface of the material box 2 3 and the upper surface of the material box 2 3, is opened, so that the material enters the material box 1 2 through the discharge port. Since a partition is fixedly installed on the inner wall surface of the material box 1 2, and a weight sensor 7 is installed on the upper surface of the partition, the material will reach the top of the weight sensor 7, and the weight sensor 7 weighs the powder material. When the preset weight is reached, the valve 6 will be controlled to close. At this time, the powder pump 8 connected below the weight sensor 7 is turned on, which will cause the material box 2 3 to be sucked, as shown in FIG. Figure 3 As shown, the material will evenly enter the first row of troughs on the upper surface of the material tray 9 through the three discharge ports 5, and then the cylinder 13 installed on the side surface of the bracket 1 is opened, so that the piston rod of the cylinder 13 pushes the material tray 9 to move. Since the material box 12 is set to an n-shaped structure, the material tray 9 can slide to the left, so that the second row of troughs of the material tray 9 corresponds to the three discharge ports 5, and then the valve 6 is opened, so that the material in the material box 2 3 enters the material box 12 again, and the amount of material is controlled by weighing through the weight sensor 7. Then, the powder pump 8 allows the material to pass through the discharge port 5 to fill the trough of the material tray 9, and so on and so forth, so that the troughs on the upper surface of the material tray 9 are all filled, so that the amount of material in each trough is uniform, so that the volume of subsequent powder molding is the same, and the product quality is improved.

[0035] Example 2

[0036] The powder molding press is also provided with a molding and discharging structure, through which the materials can enter the collecting box 14 from the lower surface of the material tray 9 after molding, specifically:

[0037] The bracket 1 is also connected to a forming and discharging structure, which controls the baffle 12 to be pulled out so that the pressed material enters the collecting box 14. The forming and discharging structure includes a material tray 9, which is slidably placed on the inner upper surface of the bracket 1. The side surface of the material tray 9 is fixedly connected to the piston rod of a cylinder 13, and the cylinder 13 is fixedly installed on the side surface of the bracket 1. A plurality of material troughs are provided on the upper surface of the material tray 9, and a baffle 12 is slidably installed on the front surface of the material tray 9. The upper surface of the baffle 12 is provided with a slot. A limit block 11 is fixedly installed on the front surface of the material tray 9, and a card block 10 is slidably penetrated on the upper surface of the limit block 11. A cylinder 2 15 is installed on the upper surface of the bracket 1, and the lower end of the piston rod of the cylinder 2 15 is fixedly connected to a pressure plate 16. The lower end of the card block 10 corresponds to the slot provided on the upper surface of the baffle 12.

[0038] Furthermore, when the powder in the trough on the upper surface of the tray 9 is filled, the cylinder 13 will control the tray 9 to slide to the right through the piston rod, so that the lower surface of the tray 9 corresponds to the opening of the bracket 1, and then the cylinder 2 15 on the upper surface of the bracket 1 is opened, so that the cylinder 2 15 controls the pressing plate 16 to move downward, as shown in FIG. Figure 2 As shown, the lower surface of the pressing plate 16 is provided with a pressing block corresponding to the groove of the material tray 9. After the pressing plate 16 squeezes the powder in the material trough of the material tray 9 into shape, as shown in FIG. Figure 5 As shown, the limit block 11 fixed on the front surface of the material tray 9 slides through the connected block 10 and slides upward, so that the block 10 loses engagement with the slot set on the upper surface of the baffle 12, and then the baffle 12 is pulled out from the front surface of the material tray 9, so that the molding material in the material trough falls through the lower surface of the material tray 9, and then falls downward through the opening of the bracket 1, and will enter the collection box 14, and then the baffle 12 is slid back into the material tray 9, so that the block 10 slides and engages with the baffle 12 again, which is convenient for next use.

[0039] Working principle: When using the powder molding press equipped with a weighing feeding structure, a weighing unloading structure is provided, which can control the amount of material unloaded from the material box 2 3 through the weight sensor 7 in the material box 1 2. The molding discharge structure controls the baffle 12 to be pulled out so that the pressed material enters the collecting box 14, thereby increasing the overall practicality.
