Description

Technical Field

[0001] This utility model relates to the field of casting equipment technology, and in particular to a casting wax pressing device that prevents splashing. Background Technology

[0002] In the casting wax pressing process, a wax pressing device is used to fill the mold with wax. The mold cavity and the sprue are filled with wax. To ensure that the mold is completely filled with wax, a certain pressure is generally required when injecting wax into the mold. However, the delivery pipe and nozzle device are hollow and lack a buffer area. Therefore, under high pressure, the liquid flow rate is too fast, and the amount of wax injected may slightly exceed the mold cavity capacity. After the pressurized wax fills the mold cavity, if there is a gap between the sprue and the wax injection port of the wax pressing device, the wax will splash. The splashed wax may burn the operator, and the splashed wax needs to be cleaned up by the operator, increasing unnecessary workload. Therefore, in order to further improve the practicality of the casting wax pressing device, we propose a splash-proof casting wax pressing device to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a splash-proof casting wax pressing device. This device uses a nozzle device in the injection mold, and staggered flow channels, guide plates, and flow grooves are respectively arranged on the inner walls of the nozzle device's guide pipe, guide tube, and nozzle head. This forms a buffer zone for liquid flow. When liquid enters the nozzle, the flow velocity gradually stabilizes due to the delay effect of the buffer zone. Combined with the effect of the buffer ring, this reduces the impact and splashing of the liquid. When the liquid is ejected, the buffer ring absorbs some of the dynamic impact, playing a shock-absorbing role. Furthermore, the guide pipe and nozzle head have the same shape, both being progressively conical. The progressively conical design, with the nozzle tip gradually narrowing towards the port, causes the fluid velocity to change slowly during ejection, reducing the instantaneous impact force of the fluid ejection and thus reducing the potential impact on the equipment and the surrounding environment.

[0004] This utility model also provides a casting wax pressing device with the above-mentioned anti-splash feature, comprising: a movable platform, an electric hydraulic rod fixedly connected to the upper surface of the movable platform, a material conveying pipe fixedly connected to the output end of the electric hydraulic rod passing through the movable platform, an electric telescopic rod fixedly connected to the bottom surface of the movable platform, four electric telescopic rods symmetrically arranged, a casting table fixedly connected to the output end of the electric telescopic rod, a nozzle device fixedly connected to the bottom end of the material conveying pipe, the nozzle device consisting of a guide pipe, a drain pipe, a guide tube, a nozzle head, and a buffer ring, and a casting pressure plate fixedly connected at the connection between the guide pipe and the drain pipe.

[0005] According to the present invention, a splash-proof casting wax pressing device is provided, wherein a connecting groove is fixedly opened on the bottom surface of the movable platform, a protective door is rotatably connected to the upper surface of the casting platform, and a second protective door is fixedly connected to the upper surface of the casting platform, the second protective door and the first protective door forming a rectangular protective cover. This allows the casting platform to not only allow the operator to observe the operation of the equipment, but also prevents wax liquid from splashing into the surrounding environment.

[0006] According to the present invention, a splash-proof casting wax pressing device is provided, wherein the width and thickness of the protective door and the second protective door match the connecting groove, and both the protective door and the second protective door are made of transparent high-density glass. This device is used to assist in fixing the connection between the moving platform and the casting platform, and to facilitate operator observation of the equipment.

[0007] According to the present invention, a splash-proof casting wax pressing device is provided, wherein a plurality of drainage grooves are evenly formed inside the drainage pipe, and a plurality of guide plates are fixed inside the drainage pipe. These form a buffer zone, slowing down the flow of heated wax material after it enters the drainage pipe, thus gradually stabilizing the flow rate.

[0008] According to the present invention, an anti-splash casting wax pressing device is provided with several guide grooves inside the nozzle head, and a buffer ring is fixedly connected to the bottom surface of the nozzle head. The buffer ring is made of elastic silicone. When the wax is sprayed out, this material can absorb part of the dynamic impact, thus playing a shock-absorbing role.

[0009] According to the present invention, a casting wax pressing device with anti-splashing is provided, wherein the shape of the guide tube is the same as the shape of the nozzle head, so that the flow rate of the wax changes slowly when it is sprayed out, thereby reducing the instantaneous impact force of the wax spray.

[0010] According to the present invention, an anti-splatter casting wax pressing device is provided, wherein the positions of the flow channel and the guide plate are staggered, and the positions of the flow channel and the guide plate correspond to each other. This is used to adjust the distance and speed of the wax spray, thereby affecting the degree of wax splatter.

[0011] According to the present invention, a splash-proof casting wax injection device has a mold platform fixedly connected to the upper surface of the casting table, the mold platform being located directly below the nozzle device. This mold platform is used to place and fix the mold, allowing for better injection of wax into the mold.

[0012] Beneficial effects: By staggering the inner walls of the nozzle device in the injection mold with the guide pipe, guide tube and nozzle head, a buffer zone for liquid flow is formed. When the liquid enters the nozzle, the flow velocity gradually stabilizes due to the delay effect of the buffer zone. Combined with the effect of the buffer ring, the impact and splashing of the liquid are reduced. When the liquid is ejected, the buffer ring can absorb part of the dynamic impact and play a role in shock absorption. The guide pipe and the nozzle head have the same shape, which is a progressive cone. The progressive cone design narrows from the tip of the nozzle to the port, so that the flow velocity changes slowly when the fluid is ejected, reducing the instantaneous impact force of the fluid jet.

[0022] Reference Figure 1-5This utility model discloses a splash-proof casting wax pressing device, comprising: a movable platform 2 for moving a nozzle device 8 and a casting pressure plate 9; an electric hydraulic rod 4 fixedly connected to the upper surface of the movable platform 2 for pressing and casting the mold; a material conveying pipe 7 fixedly connected to the output end of the electric hydraulic rod 4 through the movable platform 2 for conveying wax to the nozzle head 83; an electric telescopic rod 3 fixedly connected to the bottom surface of the movable platform 2, four of which are symmetrically arranged for smoothly lifting the movable platform 2; a casting platform 1 fixedly connected to the output end of the electric telescopic rod 3 for fixing the mold platform 6 and the mold; a nozzle device 8 fixedly connected to the bottom end of the material conveying pipe 7; the nozzle device 8 consists of a conduit, a guide pipe 81, a guide pipe 82, a nozzle head 83, and a buffer ring 84, which forms a nozzle structure that can create a uniform and stable flow of wax and prevent wax splashing; and a casting pressure plate 9 fixedly connected to the connection between the conduit and the guide pipe 81, so that the mold remains in a pressed state after wax is injected, ensuring the cooling and solidification of the wax and preventing wax splashing.

[0023] The bottom surface of the moving platform 2 is fixedly provided with a connecting groove 201. A protective door 5 is rotatably connected to the upper surface of the casting platform 1, and a second protective door is fixedly connected to the upper surface of the casting platform 1. The second protective door and the fifth protective door form a rectangular protective cover, allowing the casting platform 1 to not only allow operators to observe the equipment operation but also prevent wax from splashing into the surrounding environment, thus avoiding pollution. The width and thickness of the second and fifth protective doors match the connecting groove 201. Both the second and fifth protective doors are made of transparent high-density glass, used to assist in fixing the connection between the moving platform 2 and the casting platform 1, and to facilitate operator observation of the equipment. Several drainage grooves 801 are evenly provided inside the drainage pipe 81, and several guide plates 802 are fixed inside the guide pipe 82, forming a buffer zone to slow down the flow of heated wax after it enters the drainage pipe 81 due to the delay effect of the buffer zone. The flow gradually stabilizes, thus reducing impact and splashing. Several guide grooves 803 are provided inside the nozzle head 83. A buffer ring 84 is fixedly connected to the bottom surface of the nozzle head 83. The buffer ring 84 is made of elastic silicone. When the wax is sprayed out of the nozzle head 83, this material can absorb part of the dynamic impact and play a role in shock absorption. The shape of the guide tube 81 is the same as the shape of the nozzle head 83, so that the flow rate of the wax changes slowly when it is sprayed out, reducing the instantaneous impact force of the wax spray. The guide groove 801 and the guide plate 802 are staggered. The positions of the guide groove 801 and the guide groove 803 correspond to each other and are used to adjust the distance and speed of the wax spray, so as to affect the degree of wax splashing. A mold table 6 is fixedly connected to the upper surface of the casting table 1. The mold table 6 is located directly below the nozzle device 8 and is used to place and fix the mold so as to better inject the wax into the mold.

[0024] Working Principle: When using this anti-splash casting wax pressing equipment, firstly, the moving platform 2 is raised using the electric telescopic rod 3, disengaging the protective doors 5 and 2 from the connecting groove 201. Then, the protective door 5 is opened, and the mold is fixed via the mold table 6. Next, the moving platform 2 is lowered using the electric telescopic rod 3, causing the protective doors 5 and 2 to insert into the connecting groove 201, thus forming a rectangular protective cover. Then, through the hydraulic system of the anti-splash casting wax pressing equipment, liquid wax is injected into the fixed mold via the conveying pipe 7 and the nozzle device 8. The wax liquid... When the wax passes through the guide pipe 81, guide pipe 82 and nozzle head 83 in the nozzle device 8, the staggered arrangement of the guide groove 801, guide plate 802 and guide groove 803 ensures that the wax maintains a stable pressure during the pressing process and reduces splashing caused by pressure fluctuations. The buffer ring 84 also reduces the instantaneous impact force of fluid jet. After the wax is injected into the mold, the electric hydraulic rod 4 is used to keep the casting plate 9 in a pressing state to ensure the cooling and solidification of the wax and prevent splashing. After the wax mold is solidified, the solidified wax mold is removed from the mold.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
