Description

Technical Field

[0001] This utility model relates to the field of raw material forming technology, specifically to a forming and pressing mold device. Background Technology

[0002] In the pressing process, Nd:YAG raw materials are generally pressed using an isostatic pressing machine to apply hydraulic pressure to the raw materials.

[0003] This method has the following drawbacks: 1. The original equipment is expensive (the price range of isostatic pressing equipment is 50,000-300,000 RMB); 2. The isostatic pressing equipment shaped the raw material into an elliptical shape after hydraulic pressing, requiring secondary processing before it can be placed in the container. This is complicated, involves many procedures, has many sources of pollution, and produces irregular finished products; 3. During the furnace loading process, the irregular shape of the raw material and finished product can easily cause leakage, leading to furnace shutdown due to leaks.

[0004] Therefore, it is necessary to propose a molding and pressing die device that is simple to operate, has low die cost and is easy to process; the operation process is simple, there are few pollution sources, and the finished product specifications are uniform. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a molding and pressing mold device. The device is simple to operate, the mold cost is low and easy to process; the operation process is simple, there are few pollution sources, and the finished product specifications are uniform.

[0006] The purpose of this utility model is achieved through the following technical solution: a molding and pressing mold device, including a lower mold for placing raw materials and an upper mold that matches the lower mold, wherein the upper mold and the lower mold are arranged opposite each other, and a lifting platform for driving the lower mold to move closer to or away from the upper mold is provided on the lower side of the lower mold, and a pressure pump for driving the lifting platform is connected to the lifting platform.

[0007] The pressure pump is connected to a foot pedal for driving its operation.

[0008] The pressurization pump is equipped with a pressure gauge.

[0009] The lifting platform includes a mother platform, and a slide is slidably mounted on the upper end of the mother platform, with the lower mold located on the upper end of the slide.

[0010] The mother platform is provided with at least one connecting rod, the connecting rod is provided with a base plate, and the upper mold is provided on the lower side of the base plate.

A square block is placed at the end of the telescopic rod, and a wedge block is placed on the side of the square block away from the telescopic rod. The lower mold has an annular groove on its periphery that matches the position and shape of the square block. The inner wall of the annular groove has wedge-shaped openings that match the number, position, and shape of the wedge blocks. A return spring is sleeved on the telescopic rod, with its two ends connected to the inner wall of the groove and the square block, respectively.

[0012] The lower end of the lower mold is frustum-shaped.

[0013] The upper mold has a cross-sectional dimension of 96cm*50cm.

[0014] The lower mold has a cross-sectional dimension of 96cm*120cm.

[0015] The beneficial effects of this utility model are:

[0016] (1) The mold's external dimensions determine the shape of the finished product raw material. With uniform shape, the finished product can be produced in batches according to ideal standards.

[0017] (2) Improved work efficiency, uniform shape, avoidance of secondary processing, and reduction of labor intensity.

[0018] (3) The finished product raw materials are regular and the heating process is controllable, avoiding boiler leakage and shutdown, reducing costs and increasing output. Attached Figure Description

[0024] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] It should be noted that the directional concepts of "left", "right", "up", "down", "front", "back", "inner", and "outer" in the following scheme are all relative directions, and will not be listed one by one here.

[0026] A molding die device, reference Figures 1-4 The system includes a lifting platform 3. The lifting platform 3 consists of a mother platform 7 mounted on the ground and a slide platform 8 that slides through the mother platform 7. Two connecting rods 9 are mounted on the upper end of the mother platform 7. A base plate 10 is mounted between the two connecting rods 9. A lower mold 1 is detachably mounted on the upper end of the slide platform 8. An upper mold 2 is mounted on the lower side of the base plate 10. The upper mold 2 and the lower mold 1 are positioned opposite each other.

[0027] A pressure pump 4 is connected to the mother platform 7. The pressure pump 4 is used to supply and discharge air into the mother platform 7, thereby controlling the up and down movement of the slide 8. A foot pedal 5 is installed on the pressure pump 4, allowing the operator to drive the pressure pump 4 by operating the foot pedal 5. A pressure gauge 6 is installed on the pressure pump 4.

[0028] First, place the lower mold 1 above the lifting platform 3; inject the granular powder raw material into the lower mold 1, and place the upper mold 2 above the lower mold 1, with the upper mold 2 connected to the substrate 10; start the pressure pump 4, and the lifting platform 3 rises to make the lower mold 1 and the upper mold 2 squeeze the granular powder raw material against each other, observe the pressure gauge 6 to 80 MPa, maintain the pressure at 80 MPa for 20 minutes; finally, the raw material product is a cylinder with a uniform appearance and height, which can be directly placed into a container.

[0029] The upper mold has a cross-sectional dimension of 96cm * 50cm. The lower mold has a cross-sectional dimension of 96cm * 120cm.

[0030] A placement space 11 is provided on the upper side of the slide table 8. An opening 12 matching the size and shape of the lower mold 1 is provided on the upper side of the placement space 11. Multiple evenly distributed annular grooves 13 are provided on the inner wall of the placement space 11. A telescopic rod 14 is installed within each groove 13. A square block 15 is provided at one end of the telescopic rod 14, and a wedge-shaped block 16 is provided on the side of the square block 15 away from the telescopic rod 14.
