Description

Technical Field

[0001] The present application belongs to the technical field of wax pressing machines, and in particular relates to a wax pressing machine. Background Art

[0002] With the development of investment casting, many large thin-walled shells and engine structural parts in aerospace and aviation are produced using investment casting technology. The commonly used wax pressing method is to use aluminum molds, which can be manually opened and closed.

[0003] Patent publication number CN106825400B discloses a method for processing a wax mold of an impeller of a hydraulic retarder for a heavy-duty truck. The steps are as follows: turn on a dedicated wax injection machine, set the wax injection pressure and pressurization time, wax injection time and holding time according to the workpiece to be produced, and spray a parting agent on the forming mold and the die: then, drive the die and the forming mold to close together to form a wax model cavity, and then drive the upper injection nozzle and the side injection nozzle to extend into the die to start wax injection. After reaching the preset wax injection time and holding time, cooling begins. After cooling is completed, open the mold, use a rotating mechanism to eject the wax mold, and then manually remove it and place it in cooling water for cooling; take out the cooled wax mold and neatly stack it on a wax mold tray according to its geometric shape.

[0004] The above patent integrates the injection nozzle above the die, which moves with the movement of the die to complete the injection of wax liquid. There is no good protection mechanism during actual use. Since the technical steps are reduced, it is easy for the operator to be negligent and cause hand injuries, which needs to be improved. Utility Model Content

[0005] The purpose of this application is to provide a wax pressing machine that can solve the above problems.

[0006] The purpose of this application is to provide a wax pressing machine, comprising:

[0007] A frame, wherein a workbench is provided on the frame;

[0008] The wax pressing mechanism is arranged on a workbench and includes a top plate, columns arranged at four corners of the top plate, a console located on the top plate, and a wax pressing assembly located on the top plate, wherein the wax pressing assembly includes:

[0009] The oil cylinder is arranged on the top plate, and a pressure plate is arranged on the output shaft thereof;

[0010] The mold is set on the frame workbench;

[0011] A magnetic suction mechanism is provided on the workbench to fix the mold;

[0012] A protective mechanism is provided on one side of the workbench to protect the operator;

[0013] It also includes a wax injection mechanism, which is arranged on one side of the frame and is used to inject wax liquid into the mold.

[0014] Using the above-mentioned wax pressing machine, the wax pressing mechanism drives the pressure plate through the oil cylinder to apply precise pressure to the mold, which can quickly and evenly complete the pressing process of the wax mold, thereby improving production efficiency and product quality. The wax injection mechanism is directly arranged on one side of the frame, which is convenient for the rapid injection of wax liquid and improves production efficiency. The control console is located on the top plate, which is convenient for the operator to monitor and adjust the various parameters in the wax pressing process in real time to ensure that each wax mold can achieve the best molding effect. The precise control of the oil cylinder ensures that the pressure applied by the pressure plate to the mold is uniform and stable, which helps to reduce the scrap rate and improve product consistency. At the same time, the magnetic suction mechanism is used to fix the mold to ensure that the mold will not move due to external force during the pressing process. The protective mechanism is arranged on one side of the workbench to protect the operator and improve production safety.

[0015] Furthermore, the protection mechanism includes:

[0016] a contact portion, one end of which contacts the pressure plate;

[0017] a buffer portion, one end of which is mounted on a workbench;

[0018] One end of the contact portion extends into the buffer portion and forms a telescopic structure with the buffer portion.

[0019] The contact portion directly contacts the pressure plate. As the platen moves downward to compress, the contact portion extends downward with it. This design ensures that if the platen suddenly accelerates or loses control due to loss of control (such as a cylinder failure or control system malfunction) and the operator's hand remains on the mold after opening, the contact portion will first contact the protective mechanism rather than the operator's hand, effectively preventing safety accidents. The buffer portion, serving as the receiving end of the contact portion, has an internal telescopic structure that absorbs and disperses the impact force from the platen, thereby protecting the operator.

[0020] Further: the contact portion includes:

[0021] Cylinder;

[0022] A first movable plate is disposed in the cylinder;

[0023] The second movable plate is arranged in the cylinder and is parallel to the first movable plate;

[0024] Wherein, a first buffer spring is provided between the first movable plate and the second movable plate, and a second buffer spring is provided between the second movable plate and the bottom of the cylinder.

[0025] The first buffer spring between the first and second movable plates, and the second buffer spring between the second movable plate and the bottom of the cylinder, form a multi-stage buffer system. When the pressure plate applies pressure through the contact portion, this multi-stage buffer system gradually absorbs and disperses the impact force, thereby more effectively mitigating the impact and improving the protective effect. Furthermore, because the relative position between the first and second movable plates can be adjusted by the compression and recovery of the springs, the contact portion has a certain degree of adaptability. This adaptability allows the contact portion to automatically adjust its buffering effect according to different pressing requirements and pressure levels, achieving optimal protection and buffering performance.

[0026] Furthermore, the buffer portion includes:

[0027] A contact block is arranged outside the cylinder;

[0028] The push plate is arranged in the cylinder, and a connecting column is provided at the bottom thereof, and the connecting column is connected to the first movable plate;

[0029] A guide rod is provided between the contact block and the push plate and passes through the cylinder, and a guide piece is provided on the cylinder, through which the guide rod passes;

[0030] The surface of the contact block is also provided with a buffer layer, which is made of rubber.

[0031] The setting of the guide rod ensures that the movement trajectory of the push plate within the cylinder is linear and stable. The guide rod passes through the guide member (linear bearing) on ​​the cylinder. This design reduces the friction and resistance of the push plate during movement, making the movement of the push plate smoother and more stable, which not only improves the buffering effect but also extends the service life of the component. When the pressure plate applies pressure to the push plate through the contact part, the push plate transmits the force to the first movable plate through the connecting column, thereby compressing the first buffer spring and the second buffer spring. At the same time, the contact block serves as the external contact surface of the buffer part. The rubber buffer layer on its surface can further absorb and disperse the impact force, playing a double buffering role, significantly improving the buffering effect and protecting the equipment and mold from impact damage.

[0032] Furthermore, a support base is provided at the bottom of the buffer portion, the support base is installed on a workbench, and the buffer portion is rotatably connected to the support base through a connecting rod.

[0033] The buffer is rotatably connected to the support base via a connecting rod, allowing the buffer to rotate around the connecting rod, allowing the operator to switch the buffer from active to passive, and vice versa, as needed. This improves the adaptability and efficiency of the equipment. When not in use, the buffer can be rotated and moved to the outside of the workbench, saving workspace and preventing unnecessary damage or interference to the buffer when not in use.

[0034] Furthermore, a limit block is provided on the support base, the limit block is in contact with the connection and is used to limit the connecting rod. After the buffer part rotates, the angle between the connecting rod and the support base is 90°.

[0035] The design of the stopper ensures that the angle between the connecting rod and the support base is precisely maintained at 90° when the buffer is rotated to its non-use position. This not only ensures the stability and safety of the buffer when not in use, but also facilitates subsequent buffering and protection work. At the same time, without the stopper, the buffer would continue to rotate during rotation, causing the angle between the connecting rod and the support base to exceed the expected range. The presence of the stopper effectively prevents this from occurring, ensuring the safety and controllability of the buffer during rotation.

[0036] The beneficial effects of this application are:

[0037] 1. By setting up a protective mechanism on one side of the workbench, it can protect the operator and improve production safety;

[0038] 2. The contact part is in direct contact with the pressing plate. When the pressing plate moves downward for pressing, the contact part will extend downward accordingly. This design ensures that if the pressing plate suddenly accelerates or loses control due to loss of control for some reason (such as cylinder failure, control system failure, etc.), and the hand is still on the mold after opening, the contact part will first contact the protective mechanism instead of directly contacting the operator's hand, thereby effectively preventing the occurrence of safety accidents;

[0039] 3. The buffer is rotatably connected to the support base via a connecting rod, allowing the buffer to rotate around the connecting rod, allowing the operator to switch the buffer from active to non-active, and vice versa, as needed. This improves the adaptability and efficiency of the equipment. When the buffer is not in use, it can be rotated and moved to the outside of the workbench, saving workspace and preventing unnecessary damage or interference to the buffer when not in use.

DETAILED DESCRIPTION

[0044] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are 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 are within the scope of protection of this application.

[0045] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0046] The wax pressing machine provided in the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0047] Example 1:

[0048] like Figure 1 and Figure 2 As shown, the embodiment of the present application provides a wax pressing machine, comprising:

[0049] A frame 100, on which a workbench 110 is provided;

[0050] The wax pressing mechanism 200 is disposed on the workbench 110 and includes a top plate 210, columns 220 disposed at the four corners of the top plate 210, a console 230 located on the top plate 210, and a wax pressing assembly 240 located on the top plate 210. The wax pressing assembly 240 includes:

[0051] The oil cylinder 241 is provided on the top plate 210, and a pressure plate 242 is provided on its output shaft;

[0052] The mold 243 is arranged on the workbench 110 of the frame 100;

[0053] A magnetic attraction mechanism is provided on the workbench 110 and is used to fix the mold 243;

[0054] A protection mechanism 400 is provided on one side of the workbench 110 to protect the operator;

[0055] The machine frame 100 further includes a wax injection mechanism 300 , which is disposed on one side of the machine frame 100 and is used to inject wax liquid into the mold 243 .

[0056] In some implementations of the embodiments of this application, Figure 1 As shown, a wax pressing machine as described above is used. The wax pressing mechanism 200 drives the pressing plate 242 through the oil cylinder 241 to apply precise pressure to the mold 243, which can quickly and evenly complete the pressing process of the wax mold, thereby improving production efficiency and product quality. The wax injection mechanism 300 is directly arranged on one side of the frame 100, which is convenient for the rapid injection of wax liquid and improves production efficiency. The console 230 is located on the top plate 210, which is convenient for the operator to monitor and adjust the various parameters in the wax pressing process in real time to ensure that each wax mold can achieve the best molding effect. The precise control of the oil cylinder 241 ensures that the pressure applied by the pressing plate 242 to the mold 243 is uniform and stable, which helps to reduce the scrap rate and improve product consistency. At the same time, the magnetic attraction mechanism is used to fix the mold 243 to ensure that the mold 243 will not move due to external force during the pressing process. The protective mechanism 400 is arranged on one side of the workbench 110 to protect the operator and improve production safety.

[0057] Example 2:

[0058] An embodiment of the present application provides a wax press. In addition to the above-mentioned technical features, the wax press in the embodiment of the present application also includes the following technical features.

[0059] like Figure 2 and Figure 3 As shown, the protection mechanism 400 includes:

[0060] a contact portion 410 , one end of which contacts the pressure plate 242 ;

[0061] a buffer portion 420 , one end of which is mounted on the workbench 110 ;

[0062] One end of the contact portion 410 extends into the buffer portion 420 and forms a telescopic structure with the buffer portion 420 .

[0063] In the embodiment of the present application, the contact portion 410 directly contacts the pressure plate 242. When the pressure plate 242 moves downward to press, the contact portion 410 extends downward accordingly. This design ensures that if the pressure plate 242 suddenly accelerates or loses control for some reason (such as a failure of the oil cylinder 241 or a malfunction of the control system), and the operator's hand remains on the mold 243 after opening, the contact portion 410 will first contact the protective mechanism 400 rather than directly contacting the operator's hand, thereby effectively preventing the occurrence of safety accidents. The buffer portion 420 serves as the receiving end of the contact portion 410. Its internal design has a telescopic structure that can absorb and disperse the impact force from the pressure plate 242, thereby protecting the operator.

[0064] Example 3:

[0065] An embodiment of the present application provides a wax press. In addition to the above-mentioned technical features, the wax press in the embodiment of the present application also includes the following technical features.

[0066] like Figure 2 and Figure 3 As shown, the contact portion 410 includes:

[0067] Cylinder 411;

[0068] The first movable plate 412 is disposed in the cylinder 411;

[0069] The second movable plate 413 is disposed in the cylinder 411 and is parallel to the first movable plate 412;

[0070] A first buffer spring 414 is provided between the first movable plate 412 and the second movable plate 413 , and a second buffer spring 415 is provided between the second movable plate 413 and the bottom of the cylinder 411 .

[0071] In the embodiment of the present application, the first buffer spring 414 between the first movable plate 412 and the second movable plate 413, and the second buffer spring 415 between the second movable plate 413 and the bottom of the cylinder 411, form a multi-stage buffer system. When the pressure plate 242 applies pressure through the contact portion 410, the multi-stage buffer system can gradually absorb and disperse the impact force, thereby more effectively mitigating the impact and improving the protective effect. At the same time, because the relative position between the first movable plate 412 and the second movable plate 413 can be adjusted by the compression and recovery of the spring, the contact portion 410 has a certain degree of adaptability. This adaptability enables the contact portion 410 to automatically adjust its buffering effect according to different pressing requirements and pressure levels to achieve optimal protection and buffering performance.

[0072] Example 4:

[0073] An embodiment of the present application provides a wax press. In addition to the above-mentioned technical features, the wax press in the embodiment of the present application also includes the following technical features.

[0074] like Figure 2 and Figure 3 As shown, the buffer portion 420 includes:

[0075] The contact block 421 is arranged outside the cylinder 411;

[0076] The push plate 422 is disposed in the cylinder 411 and has a connecting post 423 at its bottom, which is connected to the first movable plate 412;

[0077] The guide rod 424 is disposed between the contact block 421 and the push plate 422 and passes through the cylinder 411 . The cylinder 411 is provided with a guide member 425 , and the guide rod 424 passes through the guide member 425 .

[0078] The surface of the contact block 421 is also provided with a rubber buffer layer 426. In this embodiment of the present application, the provision of a guide rod 424 ensures that the movement trajectory of the push plate 422 within the cylinder 411 is linear and stable. The guide rod 424 passes through a guide member 425 (linear bearing) on ​​the cylinder 411. This design reduces friction and resistance during the movement of the push plate 422, making the movement of the push plate 422 smoother and more stable, not only improving the buffering effect but also extending the service life of the component. When the pressure plate 242 applies pressure to the push plate 422 through the contact portion 410, the push plate 422 transmits the force to the first movable plate 412 through the connecting column 423, thereby compressing the first buffer spring 414 and the second buffer spring 415. At the same time, the contact block 421 serves as the external contact surface of the buffer portion 420. The rubber buffer layer 426 on its surface can further absorb and disperse the impact force, providing a dual buffering effect, significantly improving the buffering effect and protecting the equipment and mold 243 from impact damage.

[0079] Example 5:

[0080] An embodiment of the present application provides a wax press. In addition to the above-mentioned technical features, the wax press in the embodiment of the present application also includes the following technical features.

[0081] like Figure 2 and Figure 3 As shown, a support base 430 is provided at the bottom of the buffer portion 420 . The support base 430 is installed on the workbench 110 . The buffer portion 420 is rotatably connected to the support base 430 via a connecting rod 431 .

[0082] In the embodiment of the present application, the buffer portion 420 is rotatably connected to the support base 430 via a connecting rod 431, allowing the buffer portion 420 to rotate about the connecting rod 431, allowing the operator to switch the buffer portion 420 from an active state to an idle state, or vice versa, as needed. This improves the adaptability and efficiency of the equipment. When the buffer portion 420 is not in use, it can be rotated and moved to the outside of the workbench 110, which not only saves workspace but also avoids unnecessary damage or interference to the buffer portion 420 when it is not in use.

[0083] Furthermore, a limit block 432 is provided on the support base 430 , and the limit block 432 is in contact with the connection and is used to limit the connecting rod 431 . After the buffer portion 420 rotates, the angle between the connecting rod 431 and the support base 430 is 90°.

[0084] In some embodiments of the present application, the design of the stopper 432 allows the angle between the connecting rod 431 and the support base 430 to be precisely maintained at 90° when the buffer 420 is rotated to a non-use state. This not only ensures the stability and safety of the buffer 420 when not in use, but also facilitates subsequent buffering and protection work. At the same time, if there is no stopper 432, the buffer 420 will continue to rotate during the rotation process, causing the angle between the connecting rod 431 and the support base 430 to exceed the expected range. The presence of the stopper 432 effectively prevents this from occurring, ensuring the safety and controllability of the buffer 420 during the rotation process.

[0085] It should be noted that, in this article, the terms "comprise", "include" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising 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 device. In the absence of further restrictions, an element defined by the statement "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device comprising the element. In addition, it should be noted that the scope of the methods and devices in the embodiments of the present application is not limited to performing functions in the order shown or discussed, and may also include performing functions in a substantially simultaneous manner or in the opposite order according to the functions involved. For example, the described method may be performed in an order different from that described, and various steps may also be added, omitted, or combined. In addition, the features described with reference to certain examples may be combined in other examples.

[0086] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of this application, ordinary technicians in this field can also make many forms without departing from the purpose of this application and the scope of protection of the claims, all of which are within the protection of this application.
