[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0036] The core of the present utility model is to provide a casting mold, which enables the operator to face the opening of the upper forming cavity for precise and uniform effective spraying operation, improves the convenience and uniformity of the coating operation on the upper mold, facilitates the smooth demolding of the product, and improves the casting qualification rate of the product.

[0037] The casting mold provided by the present utility model includes an upper mold 01 and a lower mold 02. Please refer to Figure 1 , which is used to cast a blank into a product with a predetermined shape. Here, the blank can be heated to form a metal solution or a non-metal solution, such as an aluminum alloy solution. The specific product to be processed can be any casting, such as a piston, a bent pipe, etc., without limitation.

[0038] The lower mold 02 has a lower forming cavity with an upward opening, and the upper mold 01 has an upper forming cavity with a downward opening. The upper forming cavity and the lower forming cavity together enclose a forming cavity 10 for product processing. During processing, the solution formed by heating the blank is poured into the lower forming cavity of the lower mold 02, and the upper mold 01 is pressed on the lower mold 02. Under the pressure of the upper mold 01, the upper forming cavity and the lower forming cavity are closed.

[0039] Before the casting operation, heat-insulating materials and release agents need to be sprayed inside both the upper mold 01 and the lower mold 02. For the lower mold 02, it can be directly sprayed or smeared from top to bottom. For the upper mold 01, spraying from bottom to top is likely to result in incomplete spraying and it is impossible to know the specific spraying situation. Therefore, the upper mold 01 is connected by a rotating component so that the upper mold 01 can be rotated upward by a certain angle. Here, the angle can be any value between 90° and 180°, as long as the upper forming cavity can be exposed to facilitate the spraying operation by the operator. For example Figures 3 - 4 , Figure 3 The arrow direction in

[0040] When the rotating component rotates to drive the upper mold 01, to avoid interference between the upper and lower molds, there is a certain safety distance between them before the casting operation. The setting of this distance can avoid interference and facilitate the spraying operation of the lower mold 02.

[0041] After the upper forming cavity is exposed, the operator can directly spray heat-insulating materials or release agents into the upper forming cavity, or observe the internal spraying situation after the spraying operation, which is convenient for spraying operation, improves the uniformity and reliability of spraying, ensures the demolding effect of the product, and improves the casting qualification rate.

[0042] Optionally, the rotating component can be driven manually or electrically, as long as it can achieve the upward rotation of the upper mold 01.

[0043] The above-mentioned casting mold includes an upper mold 01, a lower mold 02 and a rotating assembly. An upper forming cavity with a downward opening is provided on the upper mold 01, and a lower forming cavity with an upward opening is provided on the lower mold 02. The upper forming cavity and the lower forming cavity enclose a forming cavity 10 for product processing. The casting liquid cools and solidifies in the forming cavity to form a product with a certain shape. The rotating assembly is connected to the upper mold 01 to drive the upper mold 01 to rotate upward so that the upper forming cavity is exposed, facilitating spraying operations. For example, by rotating the upper mold 01 upward through the rotating assembly until its opening faces the left and right sides, the operator can face the opening of the upper forming cavity to perform precise and uniform effective spraying operations, improving the convenience and uniformity of the coating operation on the upper mold, facilitating the smooth demolding of the product, and improving the casting qualification rate of the product.

[0044] Based on the above embodiment, the rotating assembly includes:

[0045] A pull head 1 for fixedly connecting with a casting machine;

[0046] A rotating shaft 3 connected to the pull head 1;

[0047] A pull rod 5 connecting the upper mold 01 and the rotating shaft 3. The rotating shaft 3 can rotate relative to the pull head 1 or the pull rod 5 can rotate around the rotating shaft 3 to realize the rotation of the upper mold 01.

[0048] Please refer to Figures 2 - 4 , the rotating assembly includes a pull head 1, a rotating shaft 3, and a pull rod 5. The pull head 1 is fixedly connected to the casting machine to form a fixation. The rotating shaft 3 is connected to the pull head 1, and the pull rod 5 is used to connect the upper mold 01 and the rotating shaft 3.

[0049] The connection between the pull rod 5 and the upper mold 01 is preferably a detachable connection, but it is necessary to ensure good connection strength, ensuring that the pull rod 5 drives the upper mold 01 to rotate when it rotates, and taking the flexibility of disassembly and assembly into account while ensuring good connection strength.

[0050] In a specific embodiment, the pull head 1 is fixed, and the rotating shaft 3 can drive the pull rod 5 to rotate relative to the pull head 1, that is, the rotating shaft 3, the pull rod 5, and the upper mold 01 are an integral part. This integral part can rotate upward relative to the pull head 1. In this case, the rotating shaft 3, the pull rod 5, and the upper mold 01 can be welded to ensure good connection strength and the safety and reliability when the upper mold 01 rotates.

[0051] In another specific embodiment, the pull rod 5 and the upper mold 01 are an integral part, and the rotating shaft 3 and the pull head 1 are an integral part. The rotating shaft 3 is fixedly arranged, enabling the pull rod 5 and the upper mold 01 to rotate around the rotating shaft 3 to realize the upward rotation of the upper mold 01.

[0052] In the above two specific embodiments, a flexible selection can be made according to the actual situation as long as the reliable and safe rotation effect of the upper mold 01 can be achieved.

[0053] Based on any of the above embodiments, the rotating shaft 3 is fixedly connected to the slider 1, the pull rod 5 is rotatably connected to the rotating shaft 3, and a locking member 4 for unlocking or locking the pull rod 5 and the rotating shaft 3 is provided on the pull rod 5.

[0054] Please refer to Figures 2 - 4 , the rotating shaft 3 is fixedly connected to the slider 1, the pull rod 5 is rotatably connected to the rotating shaft 3, and the integral component formed by the pull rod 5 and the upper die 01 can rotate upward integrally around the axis direction of the rotating shaft 3.

[0055] A locking member 4 for unlocking or locking both the pull rod 5 and the rotating shaft 3 is provided on the pull rod 5. Before the upper die 01 rotates, the locking member 4 locks both the pull rod 5 and the rotating shaft 3, and at this time, the pull rod 5 cannot rotate relative to the rotating shaft 3; when the upper die 01 rotates, the locking member 4 unlocks both the pull rod 5 and the rotating shaft 3, and at this time, the pull rod 5 and the upper die 01 can rotate relative to the rotating shaft 3; when the upper die 01 rotates to the position where the upper forming cavity is exposed, the locking member 4 locks both the pull rod 5 and the rotating shaft 3 again, and at this time, the upper die 01 cannot move, so as to facilitate the spraying operation. During the process of the locking member 4 locking both the pull rod 5 and the rotating shaft 3 again, in order to further avoid the possibility of the upper die 01 falling, a support member can be provided to support the upper die 01 when it rotates to the position where the upper forming cavity is exposed.

[0056] Taking a specific embodiment as an example, the locking member 4 is a plug pin, and the plug pin is inserted into both the pull rod 5 and the rotating shaft 3 to lock, and the plug pin is pulled out from both the pull rod 5 and the rotating shaft 3 to unlock.

[0057] Multiple plug pins can be provided, but it needs to be appropriately increased on the basis of ensuring the structural strength of the pull rod 5 and the rotating shaft 3.

[0058] Based on any of the above embodiments, the rotating shaft 3 and the slider 1 are connected by a fastener 2, and the fastener 2 passes through the rotating shaft 3 and the slider 1 to fix.

[0059] Please refer to Figures 2 - 4 , Figure 8 , the rotating shaft 3 and the slider 1 are connected by a fastener 2. In the case where the pull rod 5 can rotate relative to the rotating shaft 3, the fastener 2 passes through the rotating shaft 3 and the slider 1 to ensure the stability of the rotating shaft 3, ensure that the rotating shaft 3 does not displace, and ensure the reliable stability of the rotation of the upper die 01.

[0060] Taking a specific embodiment as an example, the fastener 2 can be a fixed pin and a split pin, so as to achieve a firm and reliable connection between the rotating shaft 3 and the slider 1.

[0061] Based on any of the above embodiments, two groups of pull rods 5 are connected to the rotating shaft 3, and at least two groups of blocking portions are provided at the end of the rotating shaft 3 to block the pull rod 5 from slipping off.

[0062] Please refer to Figures 2 - 4 , two sets of tie rods 5 are connected to the rotating shaft 3, which are correspondingly arranged at the two ends of the rotating shaft 3, so that the tie rods 5 have high stability and reliability when driving the upper mold 01 to rotate.

[0063] At least two sets of blocking parts are provided at the ends of the rotating shaft 3 to prevent the two sets of tie rods 5 from slipping off. Specifically, the cross-sectional dimension of the blocking part is larger than that of the tie rod 5, so as to effectively avoid the situation that the tie rod 5 slips off from the two ends of the rotating shaft 3 when the tie rod 5 drives the upper mold 01 to rotate. In this case, for relatively special situations, such as the tie rod 5 being deformed or the upper mold 01 being unbalanced during rotation, through the setting of the blocking part, the reliable stability of the rotation of the upper mold 01 is guaranteed to the greatest extent.

[0064] Based on any of the above embodiments, the rotating shaft 3 is rotatably connected to the pull head 1, the rotating shaft 3 is fixedly connected to the tie rod 5, and the rotating shaft 3 is connected to the output end of the driving member 8.

[0065] Please refer to Figure 1 、 Figure 5 , the rotating shaft 3 is rotatably connected to the pull head 1, and the rotating shaft 3, the tie rod 5 and the upper mold 01 are connected into an integral component. This integral component can rotate under the drive of the driving member 8, specifically, rotate around the connection point of the rotating shaft 3 and the pull head 1. By automatically controlling the rotation angle, start and stop of the upper mold 01 by the driving member 8, it saves time and effort and reduces the labor intensity. For relatively heavy casting molds, it has good application value.

[0066] The driving member 8 can specifically be a motor, and the motor can specifically be a servo motor, which can be flexibly selected according to actual needs.

[0067] Based on any of the above embodiments, the rotating shaft 3 and the pull head 1 are connected by a fastener 2, and the fastener 2 is used to unlock or lock the rotating shaft 3 and the pull head 1.

[0068] Please refer to Figure 1 、 Figure 5 、 Figure 8 , in the case where the rotating shaft 3 can rotate relative to the pull head 1, the fastener 2 is used for unlocking and locking between the two. Specifically, before the upper mold 01 rotates, the fastener 2 passes through the rotating shaft 3 and the pull head 1 to lock the two, and at this time the rotating shaft 3 cannot rotate; when the upper mold 01 needs to rotate, the fastener 2 is taken out from the rotating shaft 3 and the pull head 1, and at this time the rotation of the upper mold 01 can be realized through the rotation of the rotating shaft 3; when the upper mold 01 rotates to the position where the upper forming cavity is exposed, the fastener 2 is passed through the rotating shaft 3 and the pull head 1 again to lock the two. When the driving member 8 drives the rotating shaft 3 to rotate to the position where the upper forming cavity is exposed and stops, the upper mold 01 can stay in this position and there will be no falling situation, ensuring the safety of the spraying operation.

[0069] In this embodiment, the fastener 2 is preferably a bolt.

[0070] Based on any of the above embodiments, the upper die 01 includes an upper die body 6 and a handle 7 provided on its circumference, and anti-slip patterns are provided on the handle 7.

[0071] Whether the upper die 01 is rotated manually or electrically, the handle 7 on the upper die body 6 can provide an auxiliary function. Anti-slip patterns are provided on the handle 7 to facilitate hand gripping and ensure the safety of the operation.

[0072] Specifically, in the manual state, the rotation of the pull rod 5 relative to the rotating shaft 3 can be achieved by lifting the handle 7 by hand, so as to realize the rotation of the upper die 01.

[0073] In the electric state, if there is a circuit problem, such as a power failure, the handle 7 can be used as a backup to ensure that the upper die 01 can be rotated in any state, so as to facilitate the spraying operation effect, ensure the uniformity and effectiveness of spraying, and ensure the casting quality of the product.

[0074] Based on any of the above embodiments, the lower die 02 includes a left die 9 and a right die 11 that can move relative to each other. A core die 12 is provided between the left die 9 and the right die 11, and the left die 9, the right die 11 and the core die 12 are connected to form a lower molding cavity.

[0075] Please refer to Figures 6 - 7 , the left die 9 and the right die 11 can move relative to each other to separate from the core die 12, so that the lower die 02 can be disassembled for spraying operation, ensuring the spraying effect, facilitating demolding, and improving the casting qualification rate of the product.

[0076] The left die 9, the right die 11 and the core die 12 are connected to form a lower molding cavity. When casting, the solution after heating the blank is poured into the lower molding cavity. Specifically, the structural forms of the left die 9, the right die 11 and the core die can be flexibly designed according to the product to be processed, without limitation.

[0077] Based on any of the above embodiments, the pull head 1 drives the upper die 01 to move up or down through the rotating shaft 3, and the upper die 01 moves down to press on the lower molding cavity to close the molding cavity 10.

[0078] In this embodiment, the pull head 1 is fixedly connected to the cylinder of the casting machine. The cylinder moves up and down to drive the rotating shaft 3 up and down, correspondingly realizing the up and down movement of the upper die 01 connected to the rotating shaft 3 through the pull rod 5.

[0079] The upper mold 01 moves upward to separate the upper and lower molds by a certain safe distance, facilitating the rotation of the upper mold 01 for spraying and the spraying operation inside the lower mold 02, ensuring the spraying effect and improving the casting qualification rate of the product.

[0080] The downward movement of the upper mold 01 presses on the lower mold 02 to form a molding cavity 10, ensuring the accuracy and qualification rate of product casting. Figure 1 and Figure 7 The arrow in... can indicate the demolding direction after casting. Demolding operation can be carried out along the direction indicated by this arrow.

[0081] In this specification, each embodiment is described in a progressive manner. The key point of each embodiment is to illustrate the differences from other embodiments. For the same or similar parts among the embodiments, reference can be made to each other.
