Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of sheet material casting mould and casting system, belong to mould technical field. BACKGROUND

[0002] In the production process of ultra-thin gold products, first, gold sheet material needs to be prepared. The traditional manufacturing method is to pour molten gold into a fixed plate type horizontal mold (reference Figure 9 ), and the sheet material is made by pouring. However, the sheet material cast by using this fixed plate type horizontal mold has some problems.

[0003] Because the exposed surface of the sheet material is large, its surface is easily affected by external environment such as temperature fluctuation and air flow during casting, leading to uneven cooling. This uneven cooling can form obvious water ripples on the surface of the sheet material, and even may cause shrinkage holes, making the surface of the sheet material extremely uneven.

[0004] These uneven sheet materials will greatly affect the uniformity of the pressed strip during subsequent rolling. During the pressing process, the strip is easily bent due to the uneven surface, resulting in different thicknesses of the pressed strip, thereby affecting the overall quality and consistency of the product. In the subsequent finishing stage, this unevenness also causes the weight of the strip of the same area to be unstable, further reducing the reliability and market value of the product.

[0005] In addition, the opening of the fixed plate type horizontal mold is large, and after the material is melted and poured into the mold, it needs to rely on a fire gun for continuous heat preservation to ensure complete solidification. During this process, the high-temperature airflow of the fire gun not only increases energy consumption, but also may cause secondary thermal effects on the material surface, exacerbating the formation of water ripples and shrinkage holes.

Therefore, these terms should not be understood as a restrictive interpretation of the content of the present application.

[0040] The principles and features of the present application are described below in conjunction with examples, which are only used to explain the present application and not to limit the scope of the present application.

[0041] As shown in Figures 1-5 A sheet metal casting mold, comprising a left half mold 100, a right half mold 200 and a bottom plate 300, the cross section of the left half mold 100 is L-shaped, the cross section of the right half mold 200 is also L-shaped, the left half mold 100 comprises a first fitting end face 110 and a second fitting end face 120, the right half mold 200 comprises a third fitting end face 210 and a fourth fitting end face 220, the first fitting end face 110 cooperates with the third fitting end face 210, and the second fitting end face 120 cooperates with the fourth fitting end face 220; the bottom plate 300 is connected with the bottom edge of the right half mold 200 to form an integral structure; the left half mold 100, the right half mold 200 and the bottom plate 300 jointly enclose a casting cavity 400, and the casting cavity 400 is used to accommodate molten metal to form a sheet metal.

[0042] The first fitting end face 110 is internally provided with a first inclined chamfer 111 at the upper end, the third fitting end face 210 is provided with a first inclined flange 211 with the same slope as the first inclined chamfer 111 at the upper end, the fourth fitting end face 220 is internally provided with a second inclined chamfer 221 at the upper end, and the second fitting end face 120 is provided with a second inclined flange 121 with the same slope as the second inclined chamfer 221 at the upper end. The cooperation of the inclined chamfer and the inclined flange not only facilitates the alignment of the left half mold 100 and the right half mold 200 when they are buckled, but also enhances the sealing performance of the mold joint, effectively prevents the leakage of metal melt during casting, and ensures the quality and integrity of the cast product.

[0043] The plate casting mold further comprises an upper end cover 500 hingedly connected to an upper end of the left half mold 100 or the right half mold 200 through a hinge, and the upper end cover 500 is provided with a casting hole 501. The upper end cover 500 provides an additional safety protection layer for the casting operation, effectively prevents metal liquid splashing, and ensures the safety of the operator.

[0044] The mold of the utility model is a detachable combined vertical mold. The vertical mold refers to taking a smaller rectangular surface (smaller in area relative to other surfaces) of the mold as a casting port, and the end opposite to the casting port is a bottom surface. The height of the mold (i.e. the direction perpendicular to the bottom surface) is relatively large, which can ensure that most of the surface of the cast plate is flat, and only a small area near the casting port may not be flat.

[0046] In the embodiment, the first drive cylinder 604 and the second drive cylinder 605 of the clamping mechanism of the plate casting system both adopt a pneumatic cylinder as a power source to realize the movement of the first clamping jaw 602 and the second clamping jaw 603 on the sliding rail 601. However, according to different actual application scenes and requirements, the type of the drive cylinder can also be flexibly selected, for example, a hydraulic cylinder or an electric cylinder can also be used as an alternative solution to provide sufficient driving force and stability to ensure the stable clamping of the plate casting mold during the casting process.

[0047] The plate casting system further comprises a flame gun 700 arranged above the upper end opening of the plate casting mold. The flame gun 700 is opened during the casting process, which can continuously heat the molten metal poured into the mold, thereby ensuring the temperature stability of the molten metal during the casting process and improving the uniformity of the microstructure and mechanical properties of the cast product.

[0048] The workbench 600 is provided with a vertical support plate on one side, and the flame gun 700 is mounted on the vertical support plate through a universal connecting seat 800. Through the universal connecting seat 800, the operator can adjust the angle and position of the flame gun 700 according to actual needs, so as to realize more uniform heating and heat preservation of the molten metal in the mold, and further improve the quality and consistency of the cast product.

[0049] The first clamping jaw 602 is fixedly connected with the left half mold 100, and the second clamping jaw 603 is fixedly connected with the right half mold 200. The stable positioning of the plate casting mold in the clamping mechanism is ensured, and the possible shaking or misplacement of the mold during the casting process is avoided, thereby improving the precision and quality of the cast product.

[0050] The working method of the plate casting system of the utility model is as follows:

[0051] Firstly, according to the width of the required plate, the relative position of the left half mold 100 and the right half mold 200 is adjusted.

[0052] As shown in Figure 1 The left half mold 100 and the right half mold 200 are completely buckled, and the largest size plate can be made, as shown in Figure 5 The left half mold 100 and the right half mold 200 are misaligned and buckled, and a smaller size plate can be made.

[0053] Then, the first drive cylinder 604 and the second drive cylinder 605 are started, and the two drive cylinders will work synchronously to drive the first clamping jaw 602 and the second clamping jaw 603 to move towards each other along the slide rail 601 until they tightly hold the left half mold 100 and the right half mold 200 together to form a closed casting cavity 400.

[0054] Subsequently, the molten metal is injected from the opening above the mold, and at the same time, the flame gun 700 is opened to continuously heat the metal in the mold, so as to ensure that the molten metal maintains a stable temperature during the casting process.

[0055] After the metal is completely cooled and solidified into a plate, the first drive cylinder 604 and the second drive cylinder 605 are started again to make the first clamping jaw 602 and the second clamping jaw 603 move away from each other, so as to open the mold and take out the formed plate.

[0056] The plate casting system can accurately clamp or release the plate casting mold, ensures reliable positioning of the mold in the casting process, effectively prevents casting defects caused by mold shaking or misplacement, improves the quality of the cast product, and improves the automation level and operation efficiency of the system; since the first clamping jaw 602 and the second clamping jaw 603 can freely slide on the slide rail 601, the clamping demand of the plate casting mold of different sizes and weights can be met.

[0057] The above only describes the preferred embodiments of the utility model, and does not limit the utility model, and any modification, equivalent replacement, improvement, etc. within the spirit and principle of the utility model should be included in the protection scope of the utility model.
