Technical Field

[0001] This utility model belongs to the field of casting technology, specifically relating to an apparatus for manufacturing horizontal parting sand castings. Background Technology

[0002] Horizontal parting sand casting is a traditional casting method widely used in machinery manufacturing, the automotive industry, and other fields. This process manufactures castings by pouring molten metal into a sand mold cavity consisting of upper and lower parts. The sand mold is typically made of special sand with good heat resistance and permeability to withstand the pouring of high-temperature molten metal. Horizontal parting refers to the mold being divided into upper and lower parts along a horizontal direction, which facilitates demolding of the casting and also improves production efficiency.

[0003] Traditional manual or semi-automatic operations struggle to ensure consistent mold closure precision during each casting, easily leading to dimensional deviations and surface defects in the castings. Without automation, operators must manually perform many procedures, such as adjusting mold position and raising or lowering the upper plate, which not only increases labor intensity but also increases the risk of operational errors due to human factors. Utility Model Content

[0004] The purpose of this invention is to provide a device for manufacturing horizontal parting sand castings, aiming to solve the problem that manual or semi-automatic operations in the prior art cannot ensure consistent mold closure accuracy during each casting, which easily leads to dimensional deviations and surface defects in the castings. Without automation assistance, operators need to manually complete many processes, such as adjusting the mold position, raising or lowering the upper plate, etc., which not only increases labor intensity but may also cause operational errors due to human factors.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An apparatus for manufacturing horizontal parting sand castings, comprising:

[0007] Base plate;

[0008] A light rod, which is fixedly connected to the upper end of the base plate;

[0009] A lower parting sand casting mold is connected to the upper end of a base plate. A locking block is fixedly connected to the lower end of the lower parting sand casting mold. A locking slot is opened at the upper end of the base plate, and the locking slot matches the lower parting sand casting mold.

[0010] The upper plate is slidably connected to the light rod, and the lower end of the upper plate is fixedly connected to the upper parting sand casting mold, which is matched with the lower parting sand casting mold.

[0011] The pouring gate is located at the upper end of the upper plate.

[0012] In a preferred embodiment of this utility model, a first mounting base is fixedly connected to the side end of the base plate, a cylinder is fixedly connected to the upper end of the first mounting base, and a connecting plate is connected to the upper end of the upper plate, the connecting plate being matched with the guide rod.

[0013] As a preferred embodiment of this utility model, a second mounting seat is fixedly connected to the side end of the pouring port, and the second mounting seat is connected to the output end of the cylinder.

[0026] 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.

[0027] Example 1

[0028] Please see Figure 1-4 The present invention provides the following technical solution:

[0029] An apparatus for manufacturing horizontal parting sand castings, comprising:

[0030] Base plate 1;

[0031] The light rod 3 is fixedly connected to the upper end of the base plate 1;

[0032] The lower parting sand casting mold 7 is connected to the upper end of the base plate 1. The lower end of the lower parting sand casting mold 7 is fixedly connected to a locking block 8. The upper end of the base plate 1 is provided with a locking slot 6, which matches the lower parting sand casting mold 7.

[0033] The upper plate 9 is slidably connected to the light rod 3. The lower end of the upper plate 9 is fixedly connected to the upper parting sand casting mold 10, which is matched with the lower parting sand casting mold 7.

[0034] The pouring gate 13 is located at the top of the upper plate 9.

[0035] In a specific embodiment of this utility model, the base plate 1 is the basic structure of the entire device, providing an installation platform and support for all other components. The base plate 1 ensures the stability and robustness of the device and, through a latch 6 at its upper end, matches the latching blocks 8 of the lower parting sand casting mold 7, achieving a stable installation of the lower parting sand casting mold 7. The smooth rod 3 is fixedly connected to the upper end of the base plate 1, guiding the up-and-down sliding movement of the upper plate 9, ensuring that the upper plate 9 and the connected upper parting sand casting mold 10 can be accurately aligned with the lower parting sand casting mold 7, thereby ensuring the quality and dimensional accuracy of the casting. The lower parting sand casting mold 7 is a key component for forming the shape of the lower half of the casting. Its lower end is fixedly connected to latching blocks 8, which cooperate with the latches 6 on the base plate 1 to ensure that the lower parting sand casting mold 7 can be accurately installed in place, while providing sufficient stability to withstand the pressure during the casting process. The upper plate 9 is slidably connected to the smooth rod 3, allowing it to move vertically along the smooth rod 3. The upper plate 9 is fixedly connected to the lower parting sand mold 10, which matches the lower parting sand mold 7 to form a complete casting cavity. When the upper plate 9 descends and closes with the lower parting sand mold 7, the two combine to form the complete shape of the casting, ready to receive pouring material. The pouring gate 13 is located at the upper end of the upper plate 9 and is the entrance for introducing molten metal or other casting materials into the cavity formed by the upper and lower parting sand molds 7 and 10. The design of the pouring gate 13 takes into account hydrodynamic characteristics to ensure that the material can fill the entire cavity evenly and smoothly, avoiding defects such as bubbles and inclusions. In actual operation, once the device is ready, the upper plate 9 is driven downward by an external drive mechanism, such as a cylinder or hydraulic system (although not mentioned in the original description, it is usually part of such equipment), until it is in close contact with the lower parting sand mold 7. At this time, molten material is injected into the cavity through the pouring gate 13. After casting is completed, the upper plate 9 is lifted again to remove the formed casting.

[0036] Please refer to the details. Figure 1-4 The first mounting base 4 is fixedly connected to the side end of the base plate 1, and the cylinder 5 is fixedly connected to the upper end of the first mounting base 4. The upper end of the upper plate 9 is connected to the connecting plate 12, which matches the light rod 3.

[0037] In this embodiment: the first mounting base 4 is fixedly connected to the side end of the base plate 1, and its main function is to provide a stable mounting platform for the cylinder 5. By firmly mounting the cylinder 5 on the first mounting base 4, it can be ensured that the cylinder 5 remains stable during operation, thereby improving the reliability and accuracy of the entire system. The cylinder 5 is an actuator that drives the piston rod to move linearly by compressed air. In this embodiment, the output end of the cylinder 5 is connected to the connecting plate 12 to control the up and down movement of the upper plate 9 and the upper parting sand casting mold 10 on it. The cylinder 5 can adjust the position of the upper plate 9 to ensure smooth and accurate closing and separating actions between the upper and lower molds, which helps to improve the quality of castings and production efficiency. The connecting plate 12 is connected to the upper end of the upper plate 9 and matches the guide rod 3 to ensure that the upper plate 9 can slide smoothly under the guidance of the guide rod 3. At the same time, the connecting plate 12 is also connected to the output end of the cylinder 5 to receive power input from the cylinder 5. This design allows the upper plate 9 to slide freely vertically and also enables automated lifting operations via cylinder 5, simplifying the operation process and reducing manual intervention. The first mounting base 4, cylinder 5, and connecting plate 12 together form an automated control system, achieving precise control of the upper plate 9 and the upper parting sand casting mold 10, improving equipment efficiency and the quality stability of casting production. Furthermore, this design facilitates maintenance and adjustment, contributing to long-term stable operation.

[0038] Please refer to the details. Figure 1-4 A second mounting base 15 is fixedly connected to the side end of the pouring port 13, and the second mounting base 15 is connected to the output end of the cylinder 5.

[0039] In this embodiment, the second mounting base 15 is fixedly connected to the side end of the pouring gate 13. Its main function is to provide a connection point, allowing the pouring gate 13 to connect to the output end of the cylinder 5. This ensures that the movement of the cylinder 5 directly affects the pouring gate 13, thereby achieving precise control of the pouring process. The connection between the output end of the cylinder 5 and the second mounting base 15 means that the cylinder 5 can drive the pouring gate 13 to perform specific movements. This design allows the pouring gate 13 to adjust its position as needed. For example, during the casting process, the cylinder 5 can position the pouring gate 13 to the required height or angle to ensure that the molten material flows smoothly and evenly into the mold cavity. Furthermore, this design can also be used to control the opening and closing of the pouring gate 13, preventing accidental leakage of molten material during non-pouring operations. By connecting the output end of the cylinder 5 to the second mounting base 15 on the pouring gate 13, automated control of the pouring gate 13 is achieved. This design not only improves the accuracy and efficiency of the pouring process but also enhances the system's flexibility and safety. It allows operators to better manage the pouring process, reduce the possibility of human error, and quickly adjust equipment settings to meet the needs of different castings under varying production conditions. Furthermore, automated pouring control helps maintain a stable production process and ensures consistent product quality.

[0040] Please refer to the details. Figure 1-4 Handles 11 are fixedly connected to both ends of the upper plate 9.

[0041] In this embodiment, the handle 11 allows the operator to directly grasp and move the upper plate 9, which is particularly useful when manual adjustments are required or when the automated system malfunctions. For example, during equipment installation, commissioning, or maintenance, the operator can easily lift or lower the upper plate 9 using the handle 11, thereby facilitating mold replacement, cleaning, or other necessary maintenance work.

[0042] Please refer to the details. Figure 1-4 A pouring hopper 14 is connected to the pouring port 13, and the lower end of the pouring hopper 14 matches the upper end of the upper plate 9.

[0043] In this embodiment, the design of the pouring hopper 14 ensures that its lower end matches the upper end of the upper plate 9, meaning that the pouring hopper 14 can be precisely positioned directly above the pouring gate 13. This precise positioning helps ensure that the molten material enters the mold cavity directly, reducing the possibility of overflow or uneven filling, thereby improving the quality and consistency of the casting.

[0044] Please refer to the details. Figure 1-4 A circular base 2 is fixedly connected to the lower end of the base plate 1.

[0045] In this embodiment, the circular base 2 serves as the foundation of the entire device, ensuring stability and stability during operation. Its large contact area evenly distributes the weight of the equipment, reducing tilting or swaying caused by uneven ground or uneven weight distribution, thereby improving the stability of the casting process.

[0046] The working principle and usage process of this utility model are as follows: First, place the lower parting sand casting mold 7 in the slot 6 on the base plate 1, ensuring it is fixed in place by the locking block 8. Install the upper parting sand casting mold 10, aligning it with the lower parting sand casting mold 7 and closing it. Use the cylinder 5 or manually adjust the position of the upper plate 9 via the handle 11 to ensure the upper and lower molds fit tightly together. Adjust the position of the pouring gate 13 as needed, ensuring the pouring hopper 14 is directly opposite the pouring gate 13. If necessary, preheat the mold to avoid problems caused by temperature differences. Prepare molten metal or other casting materials, ensuring they reach a suitable pouring temperature, and pour the molten metal... The molten material is poured into the pouring hopper 14 to ensure that it flows smoothly into the pouring port 13 and into the mold cavity. The pouring process is monitored to ensure that the material fills the mold cavity evenly and to avoid problems such as air bubbles and slag inclusions. After pouring, the casting is allowed to cool naturally in the mold to an appropriate temperature, or accelerated cooling measures are taken according to process requirements. During the cooling process, the mold is kept closed to prevent external factors from affecting the quality of the casting. When the casting has completely cooled, the cylinder 5 is activated or the handle 11 is used manually to lift the upper plate 9 to separate the upper parting sand mold 10 from the lower parting sand mold 7. The formed casting is carefully removed to avoid damage.

[0047] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
