Abstract
Description
Technical Field
[0001] This invention relates to the field of chip manufacturing technology, and more specifically, to a compact benchtop chip manufacturing testing machine. Background Technology
[0002] Currently, all external environmental requirements demand that casting manufacturers in the casting industry meet numerous technical and quality requirements, such as precision, consistency, soundness, lightweight, cleanliness, and complexity. Among these, the core is mostly surrounded by high-temperature liquid metal in the mold, while the size of the supporting and positioning parts is generally small. Therefore, in addition to having the properties of general molding sand, the core is also required to have high strength, permeability, collapsibility, and collapse resistance.
[0003] The inventors' research revealed that existing core-making processes utilize decentralized equipment, leading to incomplete parameter collection and inconvenient data statistics. Obtaining cores with optimal performance requires extensive testing data to support analysis. Furthermore, unstable core-making process parameters make it difficult to achieve precise catalyst addition, resulting in inconsistent sample quality. Currently, our evaluation and monitoring data show that the equipment is up to standard, yet discrepancies still exist in the core-making results. Therefore, extensive testing data is needed to support analysis, identify the root cause of the problem, and ultimately implement the best measures to resolve it. Simultaneously, during the experimental phase, current core-making testing machines are becoming increasingly larger due to multiple process requirements, occupying significant space. Since these machines are typically installed in laboratories, their large size often prevents them from fitting inside, requiring door removal and enlargement, which is extremely inconvenient. Summary of the Invention

[0029] Please refer to Figures 1 to 4 This embodiment provides a compact benchtop core-making testing machine 100, which adopts a compact structure and achieves benchtop equipment preparation through the rational distribution of internal components, occupying little space. It also enables quantitative catalyst addition, ensuring consistent sample quality. Furthermore, it can collect multiple data points online, providing more comprehensive data.
[0030] The compact benchtop core-making testing machine 100 provided in this embodiment includes a benchtop housing 110, a core-making host 130, an air heater 150, and a catalyst metering mechanism 170. The benchtop housing 110 has a main chamber, an auxiliary chamber, and an electrical control room that are not connected to each other. The core-making host 130 is located in the main chamber and is used to make sand cores. The front of the benchtop housing 110 is provided with a core-making front door 111. The air heater 150 is located in the auxiliary chamber and is located on one side of the core-making host 130. The air heater 150 is connected to the air inlet pipe 151 of the core-making host and is used to heat the gas and send it into the core-making host. The catalyst metering mechanism 170 is located in front of the air heater 150 and is connected to the air inlet pipe 151. It is used to meterly deliver the catalyst to the core-making host.

[0031] In this embodiment, the desktop housing 110 is relatively small in size. Preferably, the dimensions of the desktop housing 110 can be 1.65m × 0.67m × 0.95m. By using a smaller desktop housing 110, components such as the core-making host 130, air heater 150, and catalyst metering mechanism 170 are all integrated into a single unit, resulting in a more compact and rational overall structure. Furthermore, the desktop housing 110 can be placed on a table for use. Simultaneously, integrating all components into a single unit housed within the desktop housing 110 allows for convenient acquisition of various parameters from the core-making host 130, air heater 150, and catalyst metering mechanism 170. In addition, the catalyst metering mechanism 170 enables the metered delivery of catalyst to the core-making host, ensuring consistent sample quality.
[0032] Furthermore, the compact benchtop core-making testing machine 100 also includes an air storage tank 180, which is located at the rear center of the core-making main unit 130 and connected to the air heater 150 for supplying air to the air heater 150. Specifically, the air storage tank 180 stores high-pressure gas, and by setting up the air storage tank 180, the stability of the gas flow rate during sand shooting can be ensured.
[0033] Furthermore, the compact benchtop core-making testing machine 100 also includes a valve control mechanism 190. The valve control mechanism 190 is located at the top rear of the core-making main unit 130. An air storage tank 180 is connected to an air heater 150 via an air storage pipe 181. A first air valve 183 is installed on the air storage pipe 181, and the first air valve 183 is communicatively connected to the valve control mechanism 190. The valve control mechanism 190 is used to control the on / off state and opening degree of the first air valve 183. Specifically, the first air valve 183 can be a solenoid valve. The valve control mechanism 190 is also located inside the benchtop housing 110, further increasing the compactness and integration of the compact benchtop core-making testing machine 100. Simultaneously, the valve control mechanism 190 can control the on / off state and opening degree of the first air valve 183, thereby controlling the amount of air entering the heater and achieving control of the heating air flow rate.

The peristaltic tube 179 passes through the peristaltic pump 177, which is used to quantitatively deliver the catalyst under the drive of the explosion-proof motor 178. Specifically, by setting up the peristaltic pump 177 and cooperating with the peristaltic tube 179, precise quantitative delivery is achieved, greatly improving the quantitative accuracy of the catalyst and further ensuring the consistency of sample quality. Simultaneously, an explosion-proof tube is installed outside the connection cable of the explosion-proof motor 178 to ensure the safe operation of the quantitative dispensing assembly 175.
[0036] It should be noted that the peristaltic pump 177 here can be a peristaltic metering pump, which can accurately inject the corresponding catalyst into the inlet pipe 151. The catalyst tank 171 is also equipped with a breather port for storing the catalyst. Furthermore, the delivery pipe 172 is located at the bottom of the catalyst tank 171, and the peristaltic pump 177 and peristaltic tube 179 are also located on the bottom side of the catalyst tank 171, facilitating connection and promoting metered delivery via the peristaltic tube 179.

[0038] In this embodiment, an electrical control component 160 is also provided inside the desktop housing 110. The electrical control component 160 is communicatively connected to the mold clamping component 133, the injection barrel component 135, and the air blowing component 137.

The sand-shooting plate 1355 is located at the bottom of the injection tube body 1351. In actual sand addition, the injection tube body 1351 can be removed and sand can be loaded into the tube from outside the equipment, or it can remain in place and simply be moved a certain distance away from the sand-shooting center for sand addition.
[0040] The air blowing assembly 137 includes an air blowing hood 1371, a sliding seat 1373, and a second driving member 1375. The sliding seat 1373 is slidably mounted on the frame 131, and the air blowing hood 1371 is mounted on the sliding seat 1373. The second driving member 1375 is throttle-connected to the sliding seat 1373 and is used to drive the sliding seat 1373 to move horizontally, so that the air blowing hood 1371 moves closer to or away from the mold closing assembly 133. Specifically, the second driving member 1375 can be a cylinder or a hydraulic cylinder, and the second driving member 1375 is installed horizontally. Meanwhile, a slide rail is provided horizontally on the frame 131, and the sliding seat 1373 is slidably mounted on the slide rail. The second driving member 1375 can drive the sliding seat 1373 to move horizontally.
[0041] The mold clamping assembly 133 includes a fixed mold 1331, a moving mold 1333, and a third drive member 1335. The fixed mold 1331 is located below the injection barrel assembly 135 and is fixedly connected to the frame 131. The moving mold 1333 is located opposite to the fixed mold 1331 and is movably connected to the frame 131. The third drive member 1335 is located on one side of the frame 131 and below the air heater 150. The third drive member 1335 is drively connected to the moving mold 1333 and is used to drive the moving mold 1333 to move closer to or away from the fixed mold 1331. Specifically, the third drive member 1335 can be a hydraulic cylinder or a pneumatic cylinder. The third drive member 1335 is installed below the air heater 150, thus having sufficient installation space to drive the moving mold 1333 at the drive end to move horizontally within sufficient space.

The moving mold 1333 is located on the left side and the fixed mold 1331 is located on the right side. The moving mold 1333 is also provided with a spring-loaded ejector rod. When the moving mold 1333 moves to the left to open the mold under the action of the third driving component 1335, the spring-loaded ejector rod can push the sand core out of the mold, making it convenient for manual removal of the sand core.
[0043] In this embodiment, the desktop housing 110 is also equipped with an electrical control box operation panel, a core-making observation window, and a pressure gauge. The electrical control box operation panel is electrically connected to the electrical control component 160 and the air valve control mechanism 190, thereby issuing electrical control commands.
