Abstract
Description
Technical Field
[0001] This utility model relates to the field of high-precision casting technology, and in particular to a wax mold transfer device for pouring cups. Background Technology
[0002] Lost-wax casting, also known as investment casting, is a precision casting process with little or no machining. It is an excellent technology in the precision casting industry with a wide range of applications. It is suitable not only for precision casting of various types and alloys, but also for producing castings with higher dimensional accuracy and surface quality than other precision casting methods. Even complex, high-temperature resistant, and difficult-to-machine castings that are difficult to produce using other precision casting methods can be obtained using investment casting.
[0003] In lost-wax casting, after the wax model is poured and trimmed, it is usually necessary to bond the wax model to a pouring cup wax model. Then, an operating rod, also known as a central column rod, is connected to the pouring cup wax model. The pouring cup and wax model can then be moved by the operating rod, and the wax model can be dipped in slurry and poured with sand by the operating rod.
[0004] Currently, when connecting the operating rod to the wax model of the pouring cup, a through hole is made coaxially through the pouring cup to allow the operating rod to pass through. After the operating rod is inserted into the through hole of the pouring cup, the step on the outer wall of the operating rod abuts against the inner bottom wall of the pouring cup. Then, molten wax is poured in to solidify the operating rod and the pouring cup into one piece. However, because the polishing of the inner bottom wall of the pouring cup wax model is not very precise during the production process, after the operating rod is inserted into the pouring cup, the operating rod is supported by the step on its outer wall against the inner bottom wall of the pouring cup under the action of gravity. This can easily cause problems with the coaxiality of the operating rod and the pouring cup, affecting the subsequent wax model splicing operation. Utility Model Content
[0005] In view of the above problems, this utility model provides a wax mold transfer device for pouring cups.
[0006] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:
[0007] A device for transferring wax molds of pouring cups is provided, including a transfer frame. An upper mounting plate and a lower mounting plate are horizontally arranged from top to bottom on the transfer frame. The upper mounting plate has a plurality of first mounting holes arranged in an array for vertical insertion of the wax molds of pouring cups. The lower mounting plate has a plurality of positioning seats arranged in an array, each positioning seat corresponding to a first mounting hole. The top of each positioning seat has a first positioning groove for engaging with the bottom of an operating lever. The bottom of the transfer frame is provided with casters.
[0008] Furthermore, the transfer frame includes uprights vertically arranged at the four corners of the transfer frame, and guide cylinders are fixedly arranged at the four corners of the lower mounting plate. The lower mounting plate is vertically slidably mounted on the transfer frame through the guide cylinders, and a limiting component is provided on the lower mounting plate to limit the sliding of the guide cylinders relative to the uprights.
[0009] Furthermore, the limiting assembly includes a brake disc, a connecting rod, a transmission screw, and a transmission sleeve. The transmission screw is horizontally rotatable below the lower mounting plate. The transmission sleeve is threaded onto the transmission screw. The middle part of the connecting rod is hinged to the lower mounting plate. One end of the connecting rod is connected to the brake disc, and the other end is hinged to the transmission sleeve. The brake disc can contact the surface of the column and restrict the guide cylinder from sliding relative to the column when the connecting rod rotates.
[0010] Furthermore, the side of the brake disc that contacts the column is provided with a friction pad.
[0011] Furthermore, a second positioning groove is provided on the lower mounting plate, and the positioning seat is detachably connected to the second positioning groove.
[0012] Furthermore, a holding plate is horizontally fixed on the transfer frame below the lower mounting plate, and the holding plate is used to place the operating lever.
[0013] The beneficial effects of this utility model are as follows: by opening a first mounting hole on the upper mounting plate, a pouring cup can be inserted and installed. A lower mounting plate is set below the upper mounting plate, and a connecting seat is set on the lower mounting plate corresponding to each first mounting hole. When the operating rod passes through the pouring cup, the bottom end of the operating rod is connected to the connecting seat on the lower mounting plate to keep the operating rod vertical. After the wax liquid connects and fixes the operating rod and the pouring cup, it can effectively ensure that the operating rod and the pouring cup are coaxial, and improve the structural dimensional accuracy when assembling the cage wax model later.

[0017] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.
[0018] This application discloses a wax mold transfer device for pouring cups, referring to... Figure 1 The system includes a transfer frame 1, on which an upper mounting plate 2 and a lower mounting plate 3 are arranged horizontally from top to bottom. The upper mounting plate 2 has several first mounting holes 21 arranged in an array, the size of which matches the size of the bottom of the pouring cup wax mold 7, allowing the pouring cup wax mold 7 to be inserted. The lower mounting plate 3 has several positioning seats 4 arranged in an array, corresponding to the area directly below the first mounting holes 21. After the operating rod 8 passes through the pouring cup wax mold 7, the bottom end of the operating rod 8 is inserted into the positioning seat 4, ensuring that the pouring cup wax mold 7 and the operating rod 8 maintain coaxiality during the wax pouring connection process, thus improving the quality of the subsequently assembled cage-type wax mold. The bottom of the transfer frame 1 is equipped with casters 11, which are casters 11 with brakes. The transfer frame 1 is also fixed with a handle, which can push the transfer frame 1 to move quickly in the workshop, or brake the casters 11 to fix the transfer frame in the current position.
[0019] In this embodiment, the transfer frame 1 includes uprights 12 located at its four corners, with the uprights 12 vertically positioned. To ensure that the lower mounting plate 3 accurately supports the bottom end of the operating lever 8 and is suitable for positioning the operating lever 8 of different lengths during the manufacturing process of different parts, guide cylinders 31 are fixed at each of the four corners of the lower mounting plate 3. The guide cylinders 31 are vertically slidably mounted on the uprights 12, allowing the lower mounting plate 3 to be vertically raised and lowered on the transfer frame via the guide cylinders 31. The lower mounting plate 3 is provided with limiting components 5 for restricting the sliding of the guide cylinders 31 relative to the uprights 12.
[0020] Reference Figure 2 In one feasible embodiment, the limiting component 5 includes a brake disc 51, a connecting rod 52, a transmission screw 53, and a transmission sleeve 54. The transmission screw 53 is horizontally rotatably disposed below the lower mounting plate 3. The transmission sleeve 54 is threaded onto the transmission screw 53. The lower mounting plate 3 is provided with a sliding groove parallel to the transmission screw 53. The transmission sleeve 54 is slidably connected to the sliding groove. The middle part of the connecting rod 52 is hinged to the lower mounting plate 3. One end of the connecting rod 52 is connected to the brake disc 51, and the other end is hinged to the transmission sleeve 54. The brake disc 51 can contact the surface of the column 12 and restrict the guide cylinder 31 from sliding relative to the column 12 as the connecting rod 52 rotates.
[0021] Specifically, the transmission screw 53 can be a bidirectional screw, located below the centerline of the lower mounting plate 3. The brake discs 51 and connecting rods 52 are symmetrically arranged on both sides of the transmission screw 53 below the lower mounting plate 3. Each transmission sleeve 54 is connected to two connecting rods. A handle is fixedly connected to one end of the transmission screw 53. By rotating the transmission screw 53 with the handle, the operator can simultaneously drive the four connecting rods 52 to rotate, causing the four brake discs 51 to simultaneously engage with the four uprights 12 of the moving frame, quickly achieving the locking and unlocking operation of the lower mounting plate 3.
[0022] In other feasible embodiments, the lower connecting plate can also be fixed by threading a limiting bolt onto the guide cylinder 31, with the limiting bolt passing through the guide cylinder 31 and abutting against the outer wall of the column 12.
[0023] Furthermore, a friction plate 55 is provided on the side of the brake disc 51 that contacts the column 12. The friction plate 55 can increase the friction between the brake disc 51 and the column 12, thereby improving the limiting and fixing effect on the lower mounting plate 3.
[0024] Furthermore, a second positioning groove 32 is provided on the lower mounting plate 3, and a connecting block is fixed at the bottom of the positioning seat 4. The positioning seat 4 is detachably connected to the second positioning groove 32 through the connecting block. By disassembling and replacing the positioning seat 4, different end structures of the operating lever 8 can be adapted, thereby improving the applicability of the device.
[0025] In this embodiment, a holding plate 6 is horizontally fixedly installed on the transfer frame 1 below the lower mounting plate 3. The holding plate 6 can be used to place the operating lever 8, making it convenient for operators to take the operating lever from the holding plate 6 for use. The lower mounting plate 3 can also be used to catch the wax dripping down during the wax pouring process, preventing the wax from dripping onto the operating lever 8 placed on the holding plate 6 and solidifying, which would cause inconvenience in inserting the operating lever 8 into the wax mold 7 of the pouring cup.
