Description

Technical Field

[0001] This utility model belongs to the field of mold technology, and in particular relates to an aluminum casting mold. Background Technology

[0002] Aluminum casting molds are crucial tools in the aluminum alloy casting process, directly determining the quality of the castings and production efficiency. Primarily used for casting aluminum alloys, precise mold design and manufacturing ensure that castings possess accurate dimensions, shapes, and excellent surface quality.

[0003] Currently, in the practical application of casting molds, it has been found that the temperature of the poured molten metal is extremely high. It is necessary to let it stand for a period of time or to cool it down with cooling equipment for a period of time before the mold can be opened and the workpiece can be removed. However, for newly prepared molds, the specific waiting time cannot be determined directly. Repeated experiments are required to determine the required standing time. This results in extremely slow production efficiency for some new workpieces, affecting the use of the mold. At the same time, the repeated experimentation method is costly and not conducive to high-efficiency casting production operations.

[0004] To address the aforementioned problems, this application proposes an aluminum casting mold. Utility Model Content

[0005] The purpose of this utility model is to provide an aluminum casting mold that solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to an aluminum casting mold, comprising a lower mold base, an upper mold base, and a gate; four temperature sensing units are evenly distributed circumferentially along the gate axis to sense the real-time temperature of different areas of the workpiece; a positioning groove is provided at the bottom of the upper mold base, and a partition plate is installed inside it; the bottom surface of the temperature sensing unit is attached to the upper surface of the partition plate; a limiting post is coaxial with the temperature sensing unit, and is threaded into the side hole near the upper region. The side hole is adjacent to the gate, and the limiting post is used to move the temperature sensing unit in and out to achieve convenient disassembly, facilitating maintenance and replacement.

[0008] Furthermore, the bottom of the limiting post is provided with a support column, which is connected to the through hole between the positioning groove and the side hole.

[0009] Furthermore, the bottom of the support column is provided with a sliding column for installing the temperature sensing unit and lowering it to the lowest position until it touches the partition plate.

[0010] Furthermore, the partition plate is provided with a ring seat through the upper protrusion, and the groove inside the ring seat is used to connect with the sliding column.

[0011] Furthermore, the lower end of the support column is provided with a downwardly protruding annular plate near the outer region, and a limit strip with elastic deformation is provided at its bottom.

[0012] Furthermore, the upper end of the ring seat is provided with an annular groove for engaging the limiting strip.

[0013] Furthermore, the circumferential distribution of the temperature sensing units is intended to prevent the inability to detect the workpiece temperature due to the failure of one of them.

[0014] This utility model has the following beneficial effects:

[0015] This invention, through the combination of positioning groove and partition plate, allows the real-time temperature of the workpiece to be detected by temperature sensing unit in the early stage of mold preparation. This facilitates the control of the settling time for mold opening, saves the trouble of repeated trials, and effectively prevents the mold from being opened prematurely during subsequent casting production, thus ensuring the production quality of aluminum castings.

[0016] This utility model allows the limiting post to be directly installed inside through the opening of the side hole, and the locking effect of the limiting strip and the annular groove forms a convenient disassembly and assembly effect, so that the temperature sensing unit can be removed for inspection and replacement at any time, solving the problem of the difficulty in repairing the built-in components, and ensuring that the workpiece temperature can be monitored in real time during each casting operation.

[0025] 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.

[0026] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0027] Please see Figure 1-4 As shown, this utility model is an aluminum casting mold, including a lower mold frame 1, an upper mold frame 2, and a gate 3;

[0028] Four temperature sensing units 11 are evenly distributed around the axis of the gate 3 to sense the real-time temperature of different areas of the workpiece. A positioning groove 6 is provided at the bottom of the upper mold frame 2, and a partition plate 8 is installed inside it. The bottom surface of the temperature sensing unit 11 is attached to the upper surface of the partition plate 8.

[0029] The limiting post 4 is coaxial with the temperature sensing unit 11 and is installed in the side hole 5 near the upper part of the threaded area. The side hole 5 is adjacent to the gate 3. The limiting post 4 is used to drive the temperature sensing unit 11 in and out to achieve the effect of easy disassembly, which is convenient for maintenance and replacement.

[0030] This embodiment provides an aluminum casting mold that facilitates the control of mold opening time. By utilizing four circumferentially distributed temperature sensing units 11, the temperature in different areas of the workpiece can be monitored in real time, thereby determining the cooling status of the workpiece. This facilitates the control of mold opening time and improves product quality. At the same time, the temperature sensing units 11 are easy to disassemble and assemble, and can be repaired and replaced at any time, making them suitable for high-temperature and easily damaged environments.

[0031] The bottom of the limiting post 4 is provided with a support post 7, which is connected to the through hole between the positioning groove 6 and the side hole 5. The bottom of the support post 7 is provided with a sliding post 10, which is used to install the temperature sensing unit 11 and lower it to the lowest position until it touches the partition plate 8. The interior of the support post 7 is a hollow structure for installing the electronic components of the temperature sensing unit 11.

[0032] Among them, the partition plate 8 is provided with a ring seat 12 through the upper protrusion 9. The groove inside the ring seat 12 is used to connect with the sliding column 10. The tapered slope at the bottom of the sliding column 10 is used to form guidance and positioning, which facilitates the installation and operation of the limiting column 4.

[0033] Among them, the lower end of the support column 7 is provided with a downward protruding annular plate near the outer area, and a limit strip 13 with elastic deformation is provided at its bottom. The upper end of the ring seat 12 is provided with an annular groove 14 for engaging the limit strip 13. When the limit strip 13 enters the annular groove 14, the inner and outer edges of the opening of the annular groove 14 first abut against the limit strip 13, causing it to shrink inward, and then automatically forming a docking.

[0034] The circumferential distribution of the temperature sensing units 11 is designed to prevent the failure of one of them from causing the inability to detect the workpiece temperature.

[0035] It is understandable that this utility model can sense the temperature of the workpiece inside the mold in real time and grasp its cooling status to prevent the mold from being opened too early or too late. In this way, the process requirements of the mold can be quickly grasped in the early stage of the preparation of the new mold, which facilitates the development of the new mold.

[0036] One specific application of the operation process in this embodiment is as follows: After the molten metal is poured into the mold cavity, during the static cooling period of the mold, the temperature sensing unit 11 senses the real-time temperature of the workpiece through the partition plate 8, and judges the temperature of the workpiece by means of circumferential distribution, so as to determine the mold opening time. This can prevent the product from not forming due to premature mold opening, and prevent the demolding difficulty due to late mold opening. It can also quickly determine the mold opening time of the new mold by recording the workpiece temperature in the early stage of the preparation of the new mold, thereby improving the production efficiency and quality of the new aluminum castings. In addition, by using the spiral connection between the limiting post 4 and the side hole 5 and the docking between the limiting strip 13 and the annular groove 14, the temperature sensing unit 11 can be removed for inspection or replacement at any time, so as to ensure that the workpiece temperature can be recorded in real time every time the mold is used, which is conducive to the process adjustment of the casting operation and to produce higher quality workpieces.
