Abstract
Description
Technical Field
[0001] This utility model relates to a casting system, specifically a stainless steel pump head six-part casting system, belonging to the field of precision casting technology. Background Technology
[0002] Precision casting, also known as lost-wax casting, is a near-net-shape liquid metal forming process. Each casting obtained through this process is the result of the collaboration of multiple processes, materials, and technologies. Investment casting involves repeatedly coating the surface of a fusible mold with several layers of refractory coating, followed by layer-by-layer sand application, drying, and hardening. The wax pattern is then melted away using heating methods such as steam and hot water to form a monolithic shell, which is then fired at high temperatures and poured to obtain the casting. Because the castings obtained by this method are dimensionally accurate, have sharp edges and corners, and smooth surfaces, closely resembling the final shape of the part, it is a near-net-shape casting process, hence the name precision casting. In precision casting, molten metal needs to be poured into the interior of the sand shell.
[0003] However, during the process of pouring molten metal into the sand shell, the operator usually uses pliers to hold the sand shell in place. The stability of the pliers is poor, and the shell may tip over during the holding process, which could lead to a safety accident. In addition, the operator needs to hold the pliers for a long time, which consumes physical strength and increases the labor intensity. Utility Model Content
[0004] The purpose of this invention is to provide a stainless steel pump head six-cast assembly casting system to solve the above problems. This system can stably fix the sand shell during the casting process, avoiding the need to hold pliers for a long time to fix it, effectively improving the safety of operation and reducing labor intensity.
[0005] This utility model achieves the above-mentioned objective through the following technical solution: a stainless steel pump head six-part casting system, including a support base, a placement groove at the top of the support base, a vertical sprue placed inside the placement groove, six ingates fixedly connected to the outer side of the vertical sprue, a casting body fixedly connected to the end of each ingate, a pouring riser cup fixedly connected to the top of the vertical sprue, a fixing structure on the support base, the fixing structure including a connecting seat and a connecting shaft, three connecting seats fixedly connected to the support base, a connecting shaft rotatably connected to the connecting seats, a rotating rod fixedly connected to the connecting shaft, multiple abutments fixedly connected to the rotating rod, the abutments abutting against the outer side of the vertical sprue, a connecting block fixedly connected to the connecting shaft, a connecting rod slidably connected to the connecting seat, a guide shaft fixedly connected to the connecting rod, the guide shaft slidably connected to the connecting block, three connecting rods fixedly connected to the same connecting ring, and one of the connecting rods having a limiting structure.
[0006] Preferably, the connecting ring is slidably connected to the support base, and the connecting rod has an overall L-shaped structure.
[0007] Preferably, the three connecting seats are arranged in a circular array about the center of the support seat, and the multiple abutments located on the same rotating rod are linearly equidistant from each other.
[0008] Preferably, a base plate is fixedly connected to the bottom end of the support base, and the center of the base plate and the support base are on the same straight line.
[0009] Preferably, the pouring riser cup has a conical structure, and the top of the vertical section of the placement groove has a trapezoidal structure.
[0010] Preferably, the limiting structure includes a guide seat and a slide rod, wherein the guide seat is fixedly connected to one of the connecting rods, the slide rod is slidably connected to the guide seat, and a locking block is fixedly connected to one end of the slide rod, the locking block engaging with the support seat.
[0011] Preferably, a spring is sleeved on the outside of the slide rod, one end of the spring abutting against the locking block, and the other end of the spring abutting against the guide seat.
[0012] Preferably, a pull block is fixedly connected to the other end of the slide rod, and the vertical cross-section of the block near the support base is trapezoidal.
[0013] The beneficial effects of this utility model are as follows: When sand shell needs to be poured, the bottom end of the vertical sprue can be placed inside the placement groove. The placement groove can provide initial positioning for the vertical sprue. Then, by pushing the connecting ring, the movement of the connecting ring will drive the three connecting rods to move. The movement of the connecting rods will drive the guide shaft to move. The movement of the guide shaft will abut against the connecting block, which will drive the connecting shaft to rotate. The connecting shaft will drive the rotating rod to move towards the vertical sprue. Multiple abutments will move together with the rotating rod. As the connecting ring moves, the limiting structure will limit its movement, preventing the connecting ring from moving. At the same time, the multiple abutments will abut against the outside of the vertical sprue, thereby achieving the positioning and fixation of the vertical sprue. Therefore, it can be used for pouring... The process achieves more stable fixation of the sand shell, preventing it from tipping over and causing safety accidents. It also avoids the need to hold pliers for a long time, which wastes a lot of physical strength, thus effectively improving the safety of operation and reducing labor intensity. During pouring, the molten metal enters the interior of the vertical runner from the riser cup, and then enters the interior of the three casting bodies at the bottom through the ingate for pouring. Then the three casting bodies at the top are poured separately. The molten metal fills the mold in the order of bottom to top, and the riser position is filled last. After pouring is completed, the limiting structure can contact the limiting of the connecting ring, and then push the connecting ring in the opposite direction so that the three rotating rods do not block the vertical runner, thus facilitating the transfer of the poured workpiece.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1 , Figure 2 and Figure 3 As shown, a stainless steel pump head six-part casting system includes a support base 2, a placement groove 3 at the top of the support base 2, a vertical sprue 6 placed inside the placement groove 3, six ingates 7 fixedly connected to the outside of the vertical sprue 6, a casting body 8 fixedly connected to the end of the ingate 7, and a riser cup 9 fixedly connected to the top of the vertical sprue 6. A fixing structure 4 is provided on the support base 2, the fixing structure 4 including connecting seats 401 and connecting shafts 402. Three connecting seats 401 are fixedly connected to the support base 2, and connecting shafts 402 are rotatably connected to the connecting seats 401. A fixed... A rotating rod 403 is connected, and multiple abutments 404 are fixedly connected to the rotating rod 403. The abutments 404 abut against the outer side of the vertical sprue 6. A connecting block 406 is fixedly connected to the connecting shaft 402. A connecting rod 407 is slidably connected to the connecting seat 401. The connecting rod 407 has an overall L-shaped structure. A guide shaft 405 is fixedly connected to the connecting rod 407. The guide shaft 405 is slidably connected to the connecting block 406. The three connecting rods 407 are fixedly connected to the same connecting ring 408. The connecting ring 408 is slidably connected to the support seat 2. One of the connecting rods 407 is provided with a limiting structure 5.
[0021] As a technical optimization solution of this utility model, such as Figure 1 and Figure 3 As shown, the three connecting seats 401 are arranged in a circular array about the center of the support seat 2, and the multiple abutments 404 located on the same rotating rod 403 are linearly and equidistantly distributed. Therefore, when the multiple abutments 404 abut against the outside of the vertical sprue 6, a more stable fixation of the vertical sprue 6 can be achieved.
[0022] As a technical optimization solution of this utility model, as shown in the figure and Figure 3 As shown, the bottom end of the support base 2 is fixedly connected to the base plate 1. The base plate 1 can increase the contact area between the support base and the ground, thereby improving the stability when placed.
[0023] As a technical optimization solution of this utility model, such as Figure 1 and Figure 3As shown, the riser cup 9 has a conical structure, which facilitates the flow of molten metal into the interior of the riser cup 9. The top of the vertical section of the placement tank 3 has a trapezoidal structure, which facilitates the placement of the vertical gating channel 6 into the interior of the placement tank 3.
[0024] As a technical optimization solution of this utility model, such as Figure 1 , Figure 2 and Figure 4 As shown, the limiting structure 5 includes a guide seat 501 and a slide rod 502. The guide seat 501 is fixedly connected to one of the connecting rods 407. The guide seat 501 can guide the movement of the slide rod 502. The slide rod 502 is slidably connected to the guide seat 501. A locking block 503 is fixedly connected to one end of the slide rod 502. The locking block 503 can fix the connecting ring 408 by engaging with the support seat 2, so that the multiple abutments 404 always abut against and fix the vertical sprue 6.
[0025] As a technical optimization solution of this utility model, such as Figure 2 As shown, a spring 504 is sleeved on the outside of the slide bar 502. Under the action of the spring 504, the locking block 503 can always be engaged with the support base 2 without the action of external force.
[0026] As a technical optimization solution of this utility model, such as Figure 4 As shown, a pull block 505 is fixedly connected to the other end of the slide rod 502. By setting the pull block 505, the slide rod 502 can be easily pulled, so that the locking block 503 and the support base 2 are not locked. The vertical cross section of the locking block 503 near the support base 2 is trapezoidal, so it can play a role in guiding the movement when the locking block 503 and the support base 2 are locked.
[0027] In use, when sand shells need to be poured, the bottom end of the vertical sprue 6 can be placed inside the placement groove 3. The placement groove 3 provides initial positioning for the vertical sprue 6. Then, by pushing the connecting ring 408, the movement of the connecting ring 408 drives the three connecting rods 407 to move. The movement of the connecting rods 407 drives the guide shaft 405 to move. The movement of the guide shaft 405 abuts against the connecting block 406, which in turn drives the connecting shaft 402 to rotate. The connecting shaft 402 drives the rotating rod 403 to move towards the vertical sprue 6. Multiple abutments 404 move together with the rotating rod 403. As the connecting ring 408 moves, the spring 504 extends, causing the locking block 503 to engage with the support base 2. At this time, the connecting ring 408 cannot move, and simultaneously, the multiple abutments 404 abut against the outer side of the vertical sprue 6. By positioning and fixing the vertical sprue 6, the sand shell can be more stably fixed during the pouring process, preventing it from tipping over and causing safety accidents. At the same time, it avoids the need to hold pliers for a long time, which wastes a lot of physical strength, thus effectively improving the safety of operation and reducing labor intensity. During pouring, the molten metal enters the interior of the vertical sprue 6 from the riser cup 9, and then enters the interior of the three lower casting bodies 8 from the ingate 7 for pouring. Then, the three upper casting bodies 8 are poured separately. The molten metal fills the mold in the order of bottom to top, and the riser position is filled last. After pouring is completed, the slide bar 502 can be pulled to prevent the locking block 503 from engaging with the support seat 2. Then, the connecting ring 408 is pushed in the opposite direction so that the three rotating rods 403 do not block the vertical sprue 6, thus facilitating the transfer of the poured workpiece.
