[0026] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0027] like Figure 1 As shown, a high-pressure powder molding device includes a molding support base 1 and a molding punching part 2 matched with the molding support base 1. Powder material is filled in the upper side of the molding support base 1, and the molding punching part 2 moving from top to bottom contacts and presses the powder material so that the powder material forms a corresponding molding tablet in the mold cavity, completing the high-pressure molding of the powder material.

[0028] Among them, guide wheels 55 are arranged on both sides of the feeding bin 5, and a wear-resistant pad 56 is arranged at the bottom of the feeding bin 5. Two guide rails 54 are arranged on the forming support base 1, which are matched with the guide wheels 55 on the corresponding side of the feeding bin 5. The cooperation of the guide rails 54 and the guide wheels 55 can achieve the effect of stably moving the feeding bin 5 and adjusting the distance between the feeding bin 5 and the forming support base 1. Among them, in order to achieve the distance adjustment, a butterfly screw 9 and a top screw 91 for connecting with the forming support base 1 are arranged on the upper side of the guide rail 54, and then through the cooperation of the butterfly screw 9 and the top screw 91, the tightening of the top screw 91 will make the butterfly screw 9 further press the guide rail 54, so that the guide rail 54 is close to the upper side of the forming support base 1, and the thinned wear-resistant pad 56 is closely fitted with the upper side of the forming support base 1, thereby effectively separating the residual powder and avoiding leakage. At the same time, the stable operation of the feeding bin 5 is achieved through the cooperation of the guide wheel 55 and the guide rail 54. In order to prevent the wear-resistant pad 56 from being thinned due to contact wear during long-term operation and affecting the processing accuracy of the forming pressing sheet, the top screw 91 is adjusted so that the butterfly screw 9 presses the wear-resistant pad 56, so that the thinned wear-resistant pad 56 fits tightly with the upper side of the cavity plate 121, thereby achieving the effect of avoiding material leakage.

[0029] like Figure 1 , Figure 2As shown, a feeding bin 5 for filling powder materials is provided on the top of the forming support base 1, and a feeding push plate 8 is provided at the right end of the feeding bin 5 to form a gap with the upper side of the forming support base 1. The feeding push plate 8 plays the role of pushing the forming tablets from the upper side of the forming support base 1 after the forming tablets are made, so as to achieve the purpose of continuously and orderly preparing the forming tablets. The gap formed between the feeding push plate 8 and the upper side of the forming support base 1 effectively avoids the subsequent cleaning problems caused by the mixing of powder materials and forming tablets caused by the feeding push plate 8 pushing the powder materials. It should be mentioned that a downward bending connecting arm 81 is provided between the feeding push plate 8 and the feeding bin 5, and the height of one end of the downward bending connecting arm 81 connected to the feeding push plate 8 is lower than the height of the other end, so that the powder materials are effectively accumulated on the lower side of the downward bending connecting arm 81 and effectively avoid obstruction to the feeding push plate 8 pushing the forming tablets. At the same time, a blanking plate 4 is provided at the right end of the forming support base 1, and a plurality of powder discharge holes distributed in an array are provided on the left side of the blanking plate 4. Therefore, after the formed tablets are discharged through the blanking plate 4, the powder material pushed and transferred to one end of the blanking plate 4 by the feeding bin 5 will be discharged through the powder discharge hole, thereby preventing the powder material from falling along the blanking plate 4 and mixing with the formed tablets.

[0030] It should be mentioned that the powder discharge hole is a waist-shaped powder discharge hole 41. The waist-shaped powder discharge hole 41 has the effect of preventing the accumulation and clogging of powder materials, thereby improving the recycling effect of powder materials. Correspondingly, a powder collecting bin 14 located at the lower left end of the waist-shaped powder discharge hole 41 is provided on the upper right side of the molding support base 1. The powder collecting bin 14 matches the waist-shaped powder discharge hole 41 up and down, so that the powder material falling through the waist-shaped powder discharge hole 41 is collected in order in the powder collecting bin 14 for standby use.

[0031] like Figure 1 , Figure 2 , Figure 3 As shown, the feeding bin 5 is connected with a push telescopic rod 7, and a bin roller 51 is arranged at the lower side of the front end of the feeding bin 5. The top of the forming support base 1 matches the bin roller 51, so as to significantly improve the stability when the pushing telescopic rod 7 drives the feeding bin 5 to move and realizes the filling of powder materials and drives the feeding push plate 8 to move and discharge materials. Among them, a feeding roller 52 is arranged in the feeding bin 5. Annular grooves 53 distributed at equal intervals are arranged on the outer peripheral side wall of the feeding roller 52, and the powder material filled in the feeding bin 5 is rotated by the feeding roller 52 so that the powder material passes through the annular groove 53 and enters the mold cavity of the forming support base 1. At the same time, a feeding motor 6 is arranged on the left side of the feeding bin 5. The feeding motor 6 is provided with a motor roller 61, and the motor roller 61 is provided with a transmission chain 62 connected to the feeding roller 52. Therefore, the feeding motor 6 drives the running motor roller 61 to rotate, and then drives the transmission chain 62 to rotate while achieving the purpose of effectively driving the feeding roller 52 to rotate.

[0032] like Figure 3 , Figure 4 As shown, a plurality of vertical limit rods 3 are arranged on the forming support base 1. In the embodiment of the present application, four vertical limit rods 3 are arranged and are respectively located at the corresponding corners to form a rectangular structure. The forming stamping part 2 is connected and fixed to the top of the vertical limit rod 3, and a stamping hydraulic cylinder 21 is arranged at the top of the forming stamping part 2, and a stamping upper die 22 connected to the movable end of the stamping hydraulic cylinder 21 is arranged at the bottom. Among them, a matching plug 23 is arranged at the bottom of the stamping upper die 22. A fixed support plate 15 and a lifting forming plate 12 located on the upper side of the fixed support plate 15 are arranged at the top of the forming support base 1. At the same time, a lifting hydraulic cylinder 11 is arranged at the bottom of the lifting forming plate 12. The lifting forming plate 12 is provided with a plurality of connecting seats 111 respectively sleeved on the corresponding vertical limit rods 3, and a cavity plate 121 matching the stamping upper die 22 is arranged in the lifting forming plate 12. The cavity is located on the cavity plate 121 and the forming support base 1, so as to achieve the effect of matching with the stamping upper die 22 and completing the high-pressure forming of the powder material. A cavity hole 122 matching the discharge port of the feeding bin 5 is provided in the cavity plate 121, and a matching sleeve 13 matching the matching plug column 23 is provided on the upper side of the cavity plate 121, so as to improve the matching accuracy between the stamping upper die 22 and the cavity plate 121. A plurality of plug-in bases 151 inserted into the corresponding cavity holes 122 are provided at the top of the fixed support plate 15, so that the plug-in bases 151 are used to support the powder material and play a role in effectively supporting the high pressure when the stamping upper die 22 and the cavity plate 121 are molded.

[0033] In summary, the present application provides a high-pressure powder molding device, which pushes the molding tablets through the feeding push plate 8, separates the powder from the molding tablets through the feeding push plate 8, and discharges the powder through the powder discharge hole, so that the high-pressure powder molding device can effectively separate the residual powder and the molding tablets. Among them, the separation effect of the powder is improved by the waist-shaped powder discharge hole 41, and the powder is collected by the powder collection bin 14, thereby further reducing the processing difficulty. At the same time, the lifting and lowering molding plate 12 is driven to rise and fall by the lifting hydraulic cylinder 11, so that the fixed support plate 15 paired with the stamping upper mold 22 to complete the molding tablet processing remains stationary, so as to improve the processing accuracy of the molding tablet, and after the lifting and lowering molding plate 12 is lowered, the molding tablet is supported by the plug-in base 151 and passes through the upper end of the cavity hole 122, so as to cooperate with the feeding push plate 8 to complete the discharge of the molding tablet.
