[0033] A feeding device for a molding machine according to an embodiment of the utility model is described below in conjunction with the accompanying drawings.

[0034] Reference Figure 1 In the structure of some molding machines, a feeding device and a pressing device are included. The feeding device includes a material moving mechanism, a powder filling mechanism arranged along the conveying direction of the material moving mechanism, a molding mechanism and a feeding mechanism. The pressing device includes a pressing mold, and the pressing mold is used to press two products to be pressed.

[0035] Specifically, the material moving mechanism includes a slider 100 and a first power assembly 110 driving the slider 100 to slide horizontally. A loading mold 120 is stacked on top of the slider 100 , and the loading mold 120 has a plurality of molding cavities 130 .

[0036] A guide rail 140 may be provided on the workbench. The guide rail 140 extends horizontally close to the pressing mold. The slider 100 is slidably provided on the guide rail 140 . Driven by the first power assembly 110 , the slider 100 transfers the loading mold 120 to different workstations.

[0037] The powder filling mechanism includes a powder filling assembly located above the loading die 120 , and the powder filling assembly is used to fill powder into the plurality of molding cavities 130 .

[0038] Reference Figure 1 , 2 And 3, the molding mechanism includes a molding die 150 located above the loading die 120, and a second power assembly 160 that drives the molding die 150 to press down. The molding die 150 has a plurality of pressing heads 170, and the pressing heads 170 are adapted to the molding cavity 130. The pressing heads 170 cooperate with the molding cavity 130 to press the powder to form a product to be pressed.

[0039] The second power assembly 160 may be a hydraulic cylinder. Driven by the hydraulic cylinder, a plurality of pressing heads 170 on the molding die 150 cooperate with the molding cavity 130 to press out a plurality of products to be pressed at one time.

[0040] The loading mechanism is used to transfer the loading die 120 with the product to be pressed to the molding machine. More precisely, the loading mechanism can transfer the loading die 120 with the product to be pressed to the pressing mold.

[0041] The pressing mold includes an upper mold 180, a middle mold and a lower mold 190. The middle mold and the lower mold 190 are respectively provided with products to be pressed. Among them, the loading mold 120 can be transferred to the pressing mold to become the middle mold. The upper mold 180, the middle mold and the lower mold 190 are combined to press the products of the middle mold and the lower mold 190.

[0042] It should be noted that the product to be pressed by the middle mold can be a U-Core, and the product to be pressed by the lower mold 190 can be a T-Core. The shape of the product to be pressed is not limited to U-Core or T-Core.

[0043] In some embodiments of the present invention, the slider 100 is provided with a positioning plate 200 , and the positioning plate 200 is provided with a positioning structure, and the positioning plate 200 positions the loading mold 120 through the positioning structure.

[0044] It can be understood that the positioning structure can be a positioning pin, and the loading mold 120 is provided with a positioning hole, and the positioning pin and the positioning hole cooperate for positioning. Of course, the positioning structure can also be a positioning groove, and the outer peripheral contour of the loading mold 120 is adapted to the positioning groove, so that the loading mold 120 is positioned on the slider 100, ensuring that the loading mold 120 can be accurately filled and the product to be pressed out.

[0045] In some embodiments of the present invention, the first power assembly 110 includes a screw rod 210 , a nut 220 threadedly driven with the screw rod 210 , and a first motor 230 driving the screw rod 210 to rotate, and the nut 220 is connected to the slider 100 .

[0046] It should be noted that the first motor 230 can be a servo motor, which drives the screw to rotate, and the screw 210 and the nut 220 are threadedly transmitted, so that the slider 100 moves linearly. Therefore, the slider 100 can accurately transport the loading mold 120 to the filling, molding and loading positions.

[0047] In some embodiments of the present invention, the powder filling assembly includes a powder box 240 and a powder outlet structure disposed at the bottom of the powder box 240 . The powder box 240 contains powder, and the powder outlet structure is used to fill the powder into the molding cavity 130 .

[0048] Therefore, the powder box 240 can store a large amount of powder without frequent addition of powder, and the powder box 240 can continuously fill the molding cavity 130 with powder through the powder outlet structure.

[0049] In a further embodiment of the present invention, referring to Figure 4 and 6 The powder discharge structure includes a feed plate 250, a guide plate 260 located below the feed plate 250, a control plate 270 horizontally slidably arranged between the feed plate 250 and the guide plate 260, and a first cylinder 280 for driving the control plate 270 to slide. The feed plate 250 is provided with a powder holding hole 290 that passes through from top to bottom, the guide plate 260 is provided with a guide hole 310 that passes through from top to bottom, the guide hole 310 and the powder holding hole 290 are staggered in the vertical direction, the control plate 270 is provided with a quantitative hole 300, the quantitative hole 300 is used to connect the powder holding hole 290 to the guide hole 310, and the control plate 270 slides to close or open the powder holding hole 290.

[0050] It can be understood that the powder in the powder box 240 can enter the powder hole 290. During the powder filling process of the powder hole 290, the control board 270 can block the bottom of the powder hole 290. After the powder filling of the powder hole 290 is completed, the first cylinder 280 can drive the control board 270 to move horizontally, so that the quantitative hole 300 is connected with the powder hole 290, which makes the quantitative hole 300 and the powder hole 290 connected. The powder in the powder hole 290 quickly fills the quantitative hole 300, and the first cylinder 280 moves the control board 270 again. At this time, the control board 270 blocks the bottom of the powder hole 290 again, and the quantitative hole 300 is connected with the guide hole 310. The powder in the quantitative hole 300 can fall into the molding cavity 130 through the guide hole 310, thereby ensuring that the amount of powder in each molding cavity 130 is consistent.

[0051] In a further embodiment of the utility model, a powder scraping mechanism is further included. The powder scraping mechanism includes a scraper 320 located in the powder box 240 and a second motor 330 driving the scraper 320 to rotate horizontally. The scraper 320 is used to scrape the powder into the powder containing hole 290.

[0052] Specifically, the powder scraping mechanism further includes a linear motion module, which can drive the second motor 330 to move horizontally.

[0053] Therefore, the second motor 330 drives the scraper 320 to rotate horizontally, and the scraper 320 scrapes the powder into the powder hole 290. In addition, the linear motion module is used to drive the second motor 330 to move horizontally to ensure that the scraper 320 can scrape the powder into each powder hole 290, thereby ensuring that each molding cavity 130 receives the powder.

[0054] In some embodiments of the present invention, referring to Figure 5The forming die 150 includes an upper limit template 340 and a lower limit template 350 , and a limit portion 440 is provided at one end of the pressing head 170 away from the loading die 120 , and the upper limit template 340 and the lower limit template 350 clamp the limit portion 440 up and down.

[0055] The lower limit template 350 may be provided with a positioning hole, and the positioning hole accommodates the pressure head 170 to pass through.

[0056] When installing the ram 170, first insert the ram 170 into the positioning hole, and the upper limit template 340 and the lower limit template 350 clamp the limit part 440 to prevent the ram 170 from falling off. Thus, a large number of rams 170 are fixed to the molding die 150, making the installation of the ram 170 more convenient.

[0057] In some embodiments of the present invention, the feeding mechanism further includes a feeding station 360 , which is arranged in the sliding direction of the slider 100 , and the slider 100 reciprocates between the powder filling mechanism, the molding mechanism and the feeding station 360 .

[0058] It is understandable that the slider 100 allows the carrier mold 120 to pass through the powder filling mechanism, the molding mechanism and the loading station 360. The loading station 360 has sufficient space to facilitate the loading mechanism to transfer the carrier mold 120.

[0059] In a further embodiment of the present invention, the loading mechanism further includes a clamp 370, a suspension 380 connected to the clamp 370, and a first moving assembly connected to the suspension 380, wherein the clamp 370 is used to transfer the loading mold 120 from the loading station 360 to the molding machine.

[0060] Specifically, the first moving component includes a first linear moving module 390 and a second linear moving module 400 extending horizontally, and a third linear moving module 410 extending up and down. The first linear moving module 390 and the second linear moving module 400 are vertically connected, and the second linear moving module 400 and the third linear moving module 410 are vertically connected. The suspension 380 includes a vertical plate and a cantilever connected to the bottom of the vertical plate. The vertical plate is connected to the third linear moving module 410, and the bottom of the cantilever is connected to the clamp 370.

[0061] Therefore, the first linear motion module 390 and the second linear motion module 400 can drive the clamping jaw 370 to move horizontally, and the third linear motion module 410 can drive the clamping jaw 370 to move up and down, so that the clamping jaw 370 can transfer the loading mold 120 to the molding machine.

[0062] Furthermore, the clamping jaw 370 is connected to the first moving assembly via a cantilever and a vertical plate, so that the clamping jaw 370 can be more easily extended into the molding machine to place and position the loading mold 120 .

[0063] In a further embodiment of the utility model, a sweeping and brushing mechanism is further included. The sweeping and brushing mechanism is located on the side of the molding mechanism close to the loading station 360. The sweeping and brushing mechanism includes a sweeping and brushing member 420 and a third power assembly 430 that drives the sweeping and brushing member 420 to move horizontally. The sweeping and brushing member 420 is used to sweep and brush the loading mold 120 at the loading station 360.

[0064] Since powder may fall onto the top surface of the loading mold 120 during the powder filling process, before the loading mold 120 is transferred to the molding machine, the third power assembly 430 can be used to drive the sweeping brush 420 to move along the top surface of the loading mold 120 to clean the powder on the top surface of the loading mold 120, thereby ensuring that the molding machine can normally press the pressed product.

[0066] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
