[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] like Figures 1 to 6 As shown, the molding die for a laboratory bench includes a base plate 1. A push plate 2 is fixedly connected to the upper surface of the base plate 1. A lower mold base 3 is fixedly connected to the upper surface of the push plate 2. A lower mold core 4 is fixedly connected to the upper surface of the lower mold base 3. A mold frame 5 is fitted onto the surface of the lower mold core 4. An upper mold core 6 is fitted onto the inner wall of the mold frame 5. An upper mold base 7 is fixedly connected to the upper surface of the upper mold core 6. First guide frames 8 are fixedly connected to both the left and right sides of the upper mold base 7. A second guide frame 8 is fixedly connected to both the left and right sides of the mold frame 5. The inner walls of the first guide frame 8 and the second guide frame 9 are both fitted with first guide posts 10, and the inner walls of the first guide frame 8 and the second guide frame 9 are both fitted with second guide posts 11. The bottom of the first guide post 10 and the bottom of the second guide post 11 are both fixedly connected with sliders 12. The bottom of the sliders 12 is provided with a T-shaped groove 13, and the inner wall of the T-shaped groove 13 is fitted with a T-shaped post 14. The bottom of the T-shaped post 14 is fixedly connected to the upper surface of the base plate 1.

[0029] The first guide frame 8 includes a first U-shaped plate 801 and a first cylinder 802. The left and right sides of the upper mold base 7 are fixedly connected to the side of the first U-shaped plate 801. The front and rear sides of the first cylinder 802 are fixedly connected to the inner wall of the first U-shaped plate 801. The inner wall of the first U-shaped plate 801 and one side of the first cylinder 802 are in contact with the surface of the first guide post 10. The inner wall of the first U-shaped plate 801 and the other side of the first cylinder 802 are in contact with the surface of the second guide post 11.

[0030] The second guide frame 9 includes a second U-shaped plate 901 and a second cylinder 902. The left and right sides of the mold frame 5 are fixedly connected to the side of the second U-shaped plate 901. The front and rear sides of the second cylinder 902 are fixedly connected to the inner wall of the second U-shaped plate 901. The inner wall of the second U-shaped plate 901 and one side of the second cylinder 902 are in contact with the surface of the first guide post 10. The inner wall of the second U-shaped plate 901 and the other side of the second cylinder 902 are in contact with the surface of the second guide post 11.

[0031] It should be noted that the T-slot 13 and T-pillar 14 work together to allow the slider 12 to move only to the left or right. The first guide pillar 10 and the second guide pillar 11 are both composed of a vertical rod and two inclined rods at either end. When the first guide frame 8 moves to the inclined rod section at the top of the first guide pillar 10 and the second guide pillar 11 and continues to move upwards, the distance between the slider 12 and the push plate 2 increases through the first guide pillar 10, the second guide pillar 11, and the first guide frame 8. Furthermore, the inclined rod sections at the bottom of the first guide pillar 10 and the second guide pillar 11 cause the mold frame 5 to move downwards a certain distance under the action of the second guide frame 9. When the upper mold base 7 reaches its highest point, the upper surface of the mold frame 5 is lower than the lower mold core 4. When the upper mold base 7 moves downward from the highest point, the distance between the slider 12 and the push plate 2 is reduced by the cooperation of the inclined rods at the top of the first guide post 10 and the second guide post 11 with the first guide frame 8. Then, the mold frame 5 moves upward a certain distance under the action of the second guide frame 9 by the inclined rods at the bottom of the first guide post 10 and the second guide post 11. When the first guide frame 8 moves to the vertical rod between the first guide post 10 and the second guide post 11, the upper surface of the mold frame 5 is higher than the upper surface of the lower mold core 4. Furthermore, the mold frame 5 will not move even if the upper mold base 7 continues to move downward. At this time, the powder can be placed in the mold frame 5 and the powder can be pressed by the upper mold core 6 at the bottom of the upper mold base 7.

[0032] like Figures 1 to 7 As shown, a column 15 is fixedly connected to the bottom of the mold frame 5, a guide ring 16 is fixedly connected to the bottom of the column 15, a third guide post 17 is fitted to the inner wall of the guide ring 16, and the bottom of the third guide post 17 is fixedly connected to the upper surface of the base plate 1.

[0033] It should be noted that the mold frame 5 is positioned by the cooperation of the upright column 15, the guide column and the third guide column 17, and the mold frame 5 can only move up or down.

[0034] like Figures 1 to 9 As shown, the front and rear sides of the upper mold base 7 are fixedly connected with a third U-shaped plate 18, and the front and rear sides of the mold frame 5 are fixedly connected with a U-shaped column 19. The left and right sides of the inner wall of the third U-shaped plate 18 are in contact with the side of the U-shaped column 19. The left and right sides of the third U-shaped plate 18 are provided with round holes 20. The inner wall of the round holes 20 and the side of the third U-shaped plate 18 are fitted with elastic fixing brackets 21.

[0035] The elastic fixing frame 21 includes a spring 2101, a third cylinder 2102, and a limiting ring 2103. Both ends of the spring 2101 are fixedly connected to one end of the third cylinder 2102. The inner wall of the circular hole 20 and the inner wall of the U-shaped column 19 are both in contact with the surface of the third cylinder 2102. The surface of the third cylinder 2102 is fixedly connected to the inner wall of the limiting ring 2103. The side of the third U-shaped plate 18 is in contact with the side of the limiting ring 2103.

[0036] It should be noted that when the third cylinder 2102 is inserted into the circular hole 20 and contacts the inner wall of the U-shaped column 19, the third cylinder 2102 can be positioned by the limiting ring 2103, and the third cylinder 2102 cannot be automatically moved out of the circular hole 20 by the spring 2101. At this time, the upper mold base 7 can be fixed together with the mold frame 5 by the cooperation of the third U-shaped plate 18, the U-shaped column 19, the circular hole 20 and the elastic fixing frame 21. At the same time, when the third cylinder 2102 is pulled out from the circular hole 20, the upper mold base 7 can be separated from the mold frame 5.

[0037] The working principle of this utility model is as follows: First, the third cylinder 2102 is pulled out from the round hole 20. Then, the mold is fixed on the brick press. Then, through the lifting structure on the brick press, the upper mold base 7 is raised a certain distance, and the first cylinder 802 in the first guide frame 8 is located at the vertical rod part between the first guide post 10 and the second guide post 11. At this time, through the cooperation of the first guide frame 8, the second guide frame 9, the first guide post 10 and the second guide post 11, the upper surface of the mold frame 5 is higher than the upper surface of the lower mold core 4. Then, the powder is placed in the mold frame 5, and through the lifting structure on the brick press, the upper mold core 6 is moved downward. Then, the upper mold core 6 is inserted into the mold frame 5 and presses the powder. At this time, through the upper mold core 6, the mold frame 5 and the lower mold core 4, the powder is pressed and shaped.

[0038] When removing the formed platform, the upper mold core 6 is first moved upward by the lifting structure on the brick press. When the first guide frame 8 moves to the inclined rod at the top of the first guide column 10 and the second guide column 11 and continues to move upward, the distance between the slider 12 and the push plate 2 is increased by the first guide column 10, the second guide column 11 and the first guide frame 8. The mold frame 5 is moved downward by the second guide frame 9 under the action of the inclined rod at the bottom of the first guide column 10 and the second guide column 11. When the upper mold base 7 rises to the highest point, the upper surface of the mold frame 5 is lower than the upper surface of the lower mold core 4, and the formed platform on the lower mold core 4 is separated from the mold frame 5. At this time, the formed platform can be removed from the lower mold core 4.

[0039] After the molded platform is removed, the upper mold base 7 moves downward from its highest point. First, through the cooperation of the inclined rods at the top of the first guide post 10 and the second guide post 11 with the first guide frame 8, the distance between the slider 12 and the push plate 2 is reduced. Then, through the inclined rods at the bottom of the first guide post 10 and the second guide post 11, the mold frame 5 moves upward a certain distance under the action of the second guide frame 9. When the first guide frame 8 moves to the vertical rod between the first guide post 10 and the second guide post 11, the upper surface of the mold frame 5 is higher than the upper surface of the lower mold core 4. By stopping the first guide frame 8 at the vertical rod between the first guide post 10 and the second guide post 11, the user can place the subsequent powder material into the mold frame 5.

[0040] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
