[0002] The molding device is a simple device that can achieve high quality, short development cycle, low cost and can verify product-related performance. In the processing and production of precious metals, they are often irregular shapes. The initial processing of the molding device can be customized to shape the product, which is convenient for the transportation and storage of precious metals.

[0003] The industry often shapes precious metals by placing liquid precious metals into a discharge box and then discharging and shaping them under the action of gravity.

[0004] Liquid precious metal is discharged and formed from the discharge port based on the weight of the metal itself. However, due to the reaction of the surface tension of the liquid, the liquid precious metal cannot be fully discharged and formed under gravity, making the process inefficient and time-consuming. Utility Model Content

[0005] In view of the above problems, the present utility model is proposed to provide a molding device with double cylinders that overcomes the above problems or at least partially solves the above problems.

[0020] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0021] Example 1

[0022] Reference Figure 1 and Figure 3, shows a schematic structural diagram of a forming device with a double cylinder of the utility model, which may specifically include: a chassis 3, a first cylinder 2, a second cylinder 5 and a processing cavity 1; the processing cavity 1 includes an upper cover 11 and a lower cavity 12; the upper cover 11 is arranged above the lower cavity 12, and a sealing component is arranged at the top of the lower cavity 12 and / or the bottom of the upper cover 11. It should be noted here that the upper cover 11 is preferably arranged directly above the lower cavity 12, including but not limited to directly above, and the upper cover 11 can also be arranged at a deflected position directly above the lower cavity 12. At this time, when the device is closed, the upper cover 11 needs to be translated to directly above the lower cavity first, and then downward to achieve closed sealing. It is more preferred to arrange the upper cover 11 directly above the lower cavity 12, so that the translation operation of the upper cover 11 can be avoided, unnecessary operations are reduced, and processing steps and costs are saved.

[0023] In addition, the upper cover 11 and the lower cavity 12 form a sealed chamber when they are closed. The sealed chamber is for better pressurizing the liquid precious metal and then accelerating the molding. It also provides a prerequisite for adding a boosting component later. If you want to boost the pressure, you need to have a closed environment first.

[0024] Furthermore, the sealing component is to set a sealing ring at the bottom end of the upper cover 11 or the top end of the lower cavity, including but not limited to setting a sealing ring, and can also be setting a sealing coating. When setting the sealing coating, the sealing matching requirements are relatively high. At this time, the inner diameter of the upper cover 11 should be slightly larger than the outer diameter of the lower cavity 12; and when choosing to set a sealing ring, taking the setting of a sealing ring at the top end of the lower cavity 12 as an example, at this time, the sealing ring is set at the inner mouth of the lower cavity 12 near the top, the outer diameter of the sealing ring is equal to the inner diameter of the lower cavity 12, and the inner diameter of the upper cover 11 is slightly larger than the outer diameter of the lower cavity 12; when the sealing ring is set on the gasket at the bottom end of the upper cover 11, at this time, the sealing ring has the same inner and outer diameters as the lower cavity 12, and the inner diameter of the upper cover 11 is the same as the inner diameter of the lower cavity 12; in this way, when working, the upper cover 11 moves downward and closes with the lower cavity 12 to form the processing cavity 1.

[0025] The upper cover 11 is connected to one end of the first cylinder 2. It should be noted that the connection between the upper cover 11 and the first cylinder 2 is to limit the horizontal movement of the upper cover 11 and to make the vertical movement of the upper cover 11 consistent with the vertical movement of the first cylinder 2. When the first cylinder 2 moves upward, the upper cover 11 also moves upward. When the first cylinder 2 moves downward, the upper cover 11 also moves downward. The upper cover 11 is connected with the second cylinder 5 when sealed by a snap-fit ​​connection. It should be noted that the second cylinder 5 is to make the upper cover 11 more stable under stress. If a single cylinder is subjected to uneven stress, it is easy to be unbalanced during operation, resulting in accidents. Therefore, it is obvious that not only two but also three or more can be set. At the same time, the second cylinder 5 is the same as the first cylinder 2, constraining the upper cover 11 so that the upper cover 11, the second cylinder 5 and the first cylinder 2 can move vertically. The snap-fit ​​connection is to better fix the upper cover 11 at a preset position. The more preferred one is Directly above the lower cavity 12, the upper cover 11 is at a preset distance from the lower cavity 12, which is the state before work. During work, the upper cover 11 shrinks downward under the action of the first cylinder 2, so that the upper cover 11 is close to the lower cavity 12. At this time, the upper cover 11 is snap-connected with the second cylinder 5 to fix the upper cover 11, and then, under the joint action of the first cylinder 2 and the second cylinder 5, it continues to shrink downward to a position where it can no longer move downward. At this time, there is also a sealing component that allows the upper cover 11 and the lower cavity 12 to form a closed cavity.

[0026] Furthermore, the upper cover 11 is also provided with a one-way vent hole for connecting a boosting component. It should be noted here that the boosting component is any mechanism for boosting the upper cover 11, such as a boosting pump, which increases the pressure in the closed cavity to subject the liquid metal to pressure, thereby accelerating the discharge and molding.

[0027] The first cylinder 2, the second cylinder 5 and the lower cavity 12 are fixed to the chassis 3 in sequence. It should be noted that the piston rod end of the first cylinder 2 is connected to the upper cover 11. When the upper cover 11 is closed, it is snap-connected with the piston rod end of the second cylinder 5, including but not limited to snap-connection, which plays a role in fixing the upper cover. It can also be a threaded connection. It should be noted that at this time, the upper cover 11 must be retracted to a preset position through the first cylinder 2, and then the upper cover 11 and the second cylinder 5 are threadedly connected by screws or bolts. The lower cavity 12 is preferably set at the center of the chassis 3, and the first cylinder 2 and the second cylinder 5 are symmetrically arranged with the lower cavity 12.

[0028] The chassis 3 is provided with a discharge port 4. Furthermore, the shape of the discharge port 4 can be any shape and can be changed according to actual production. Generally, common gold and silver are in the shape of bricks, so it is preferably set to a rectangle. If other shapes are required, the desired shape of the product can be obtained by replacing the chassis with a discharge port 4 of a different shape.

[0029] Example 2

[0030] Reference Figure 2 , showing a schematic diagram of the upper cover structure of a forming device with double cylinders of the utility model.

[0031] The upper cover 11 is a cover with a rotating component at one side and a bottom end fixedly connected to a gasket. It should be noted that the rotating component can make the upper cover 11 rotate around the first cylinder 2. When adding materials, the upper cover 11 can be rotated to deviate from the top of the lower cavity 12, and then add materials, and then turn the upper cover 11 back to the top of the lower cavity 12. The rotating component is fixedly connected to the cover, including but not limited to welding. Among them, the rotating component can be a hinge component. The hinge component is easy to use on the one hand and has excellent rotation performance on the other hand. The disadvantage is that the price is relatively high; the rotating component can also be a cover welded with a sleeve to achieve rotation, but the disadvantage is poor quality and short service life; it can also be driven by the rotation of the piston of the first cylinder 2 to drive the upper cover 11 to rotate. This method has poor effect and high requirements on the first cylinder 2. The better method is to use a hinge component, and the specific method can also be selected according to actual conditions. In addition, the gasket is also fixedly connected to the cover, including but not limited to welding, and welding is more preferred. A snap groove is provided on one end of the gasket, and the upper cover 11 and the second cylinder 5 are snap-connected through the snap groove. If other fixed connection methods are used, corresponding changes should also be made to the gasket. For example, if it is a threaded connection, a threaded hole should be provided on one end of the gasket.

[0032] Furthermore, the upper cover 11 is preferably a cylinder, one end of which is hollowed out, and the connection between the gasket and the cylinder is also hollowed out; the lower cavity 12 is also a cylinder, which is a hollow cylinder. The lower cavity 12 is arranged on the chassis 3, and the chassis is provided with a discharge port 4, which can discharge and form liquid metal.

[0033] Furthermore, the upper cover 11 is also provided with a stirring device 6, which can keep the liquid metal in a liquid state by stirring, destroying the internal balance. Secondly, when processing liquid metal with many impurities and light weight, the air between the metals can be discharged, which is more conducive to improving the quality of the molded product. The stirring device 6 is an electric stirrer, which is installed inside the upper cover, near the top. It is more preferred to set the stirring device 6 near the center of the top. The stirring device 6 is also retractable. When closed, the stirring device 6 extends to reach the lower cavity 12, at a preset distance from the chassis. When loading materials, the stirring device 6 is shortened to the upper cover 11, which is convenient for the upper cover 11 to rotate around the first cylinder 2 and then add materials. It should be noted that the length of the stirring device is limited, and the shortest length of contraction should be less than the internal depth of the upper cover 11. The maximum length is not limited. It is more preferred that the maximum length does not exceed the sum of the depth of the lower cavity 12 and the depth of the upper cover 11.

[0034] In this embodiment, the upper cover 11 is provided with a rotating part and a gasket, so that the upper cover 11 can be rotated and can be snap-connected with the second cylinder 5. These two functions are realized in one part, saving cost and space. Secondly, a stirring device 6 is provided to continuously stir the liquid metal to destroy its balance and keep it in liquid state. If it is solid, once it is blocked at the discharge port 4, it will lead to failure of discharge, affecting subsequent processing, and the removal cost is also very high.

[0035] Finally, it should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or terminal device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or terminal device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or terminal device including the elements.
