Description

Technical Field

[0001] This utility model relates to the field of low-pressure casting technology, and in particular to a low-pressure casting mold with a rapid positioning mechanism. Background Technology

[0002] Low-pressure casting is a common process in casting operations. A low-pressure casting mold is a type of mold used to fill and solidify molten metal into a mold cavity under relatively low pressure (20–60 kPa) to obtain a casting. Before use, the upper and lower molds need to be fixedly connected to the upper and lower sides of the equipment platform to allow for mold opening and closing. Because it is a casting process that uses low pressure to smoothly fill and solidify molten aluminum into the mold, the installation of the mold on the equipment platform requires a certain degree of precision to ensure that the mold gate is aligned with the injection port of the low-pressure equipment.

[0003] Currently, the installation of low-pressure casting molds involves using a forklift to lift the entire mold onto the equipment platform. Then, personnel visually align the pre-drilled mounting slots on the mold with the pre-drilled mounting grooves on the equipment platform. T-bolts are then used to connect the two, ensuring the mold is precisely fixed to the platform in a fixed direction and angle. Because the installation process requires high precision, it is slow and cumbersome. Furthermore, if the mold is not installed correctly, it can cause the gate to become blocked, leading to production interruptions and economic losses. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a low-pressure casting mold with a rapid positioning mechanism.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A low-pressure casting mold with a rapid positioning mechanism includes an upper mold plate, a lower mold plate, and an upper and lower platform plate arranged parallel to each other. The mold is characterized by: a first mounting groove on the upper surface of the lower platform plate and a second mounting groove on the lower surface of the upper platform plate; the first and second mounting grooves are not parallel to each other; a first U-shaped groove on the lower mold plate and a second U-shaped groove on the upper mold plate; the first and second U-shaped grooves correspond to the positions of the first and second mounting grooves, respectively; a first limiting block is rotatably connected in the first U-shaped groove; a second limiting block is rotatably connected in the second U-shaped groove; both ends of the first and second limiting blocks include a heavy end and a light end, respectively; the heavy end is capable of rotating downwards under gravity; the heavy end of the first limiting block protrudes from the lower surface of the lower mold plate, and the light end of the second limiting block protrudes from the upper surface of the upper mold plate.

[0007] Furthermore, a support shaft is provided on both the first limiting block and the second limiting block, and a first groove is provided in both the first U-shaped groove and the second U-shaped groove, and the support shaft is rotatably connected in the first groove.

[0008] Furthermore, a second groove is provided in both the first U-shaped groove and the second U-shaped groove. The second groove is located at the upper end of the first groove, and a pressure plate is fixedly connected in the second groove to support the limiting position of the shaft.

[0009] Furthermore, the pressure plate is fixedly connected to the second groove by bolts.

[0010] Furthermore, the heavy ends of the first and second limiting blocks are protruding structures.

[0011] Furthermore, the first mounting slot and the second mounting slot are arranged perpendicular to each other.

[0012] Furthermore, four of the first mounting slots and the first limiting blocks are arranged in parallel.

[0013] Furthermore, there are four of each of the second mounting slots and the second limiting blocks arranged in parallel.

[0014] Furthermore, the upper surface of the lower platform is provided with a third mounting groove, which is perpendicular to the first mounting groove, and the lower template is provided with a corresponding third U-shaped groove.

[0015] Furthermore, a fourth mounting groove is provided on the lower surface of the upper platform, the fourth mounting groove being perpendicular to the second mounting groove, and a corresponding fourth U-shaped groove is provided on the upper template.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] By installing rotatable limit blocks on the upper and lower templates, the forklift can directly self-calibrate the pre-reserved mounting slots on the upper and lower platforms after forking the mold onto the platform. When the mold is accurately positioned in the predetermined position on the equipment platform, the limit blocks can automatically engage in the mounting slots to achieve positioning. This allows a single person to complete the mold positioning work quickly, greatly reducing the difficulty of mold installation and making the mold installation process accurate, fast, and simple.

[0018] Other features and advantages of this invention will be set forth in the following description or may be learned by practicing this invention. Attached Figure Description

Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified.

[0028] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," "fixing," and "setting," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] like Figure 1-3 As shown, a low-pressure casting mold with a quick positioning mechanism includes an upper mold plate 2, a lower mold plate 1, and an upper plate 4 and a lower plate 3 arranged parallel to each other at the top and bottom.

[0030] A first mounting groove 31 is provided on the upper surface of the lower plate 3, and a second mounting groove 41 is provided on the lower surface of the upper plate 4. The first mounting groove 31 and the second mounting groove 41 are arranged perpendicularly to each other, thereby forming a positioning structure in a rectangular coordinate system on a horizontal plane, which is used to complete the precise positioning of the mold.

[0031] The lower template 1 is provided with a first U-shaped groove 11, and the upper template 2 is provided with a second U-shaped groove 21. The first U-shaped groove 11 and the second U-shaped groove 21 correspond to the positions of the first mounting groove 31 and the second mounting groove 41, respectively, for mutual connection and fixation. A first limiting block 12 is rotatably connected in the first U-shaped groove 11, and a second limiting block 22 is rotatably connected in the second U-shaped groove 21. The two ends of the first limiting block 12 and the second limiting block 22 are respectively the heavy end and the light end. The heavy end can rotate downward under the action of gravity. After this natural rotation by gravity, the heavy end of the first limiting block 12 can protrude from the lower surface of the lower template 1, and the light end of the second limiting block 22 can protrude from the upper surface of the upper template 2.

[0032] like Figure 2-3 As shown, a support shaft 5 passes through the first limiting block 12. Similarly, a support shaft 5 also passes through the second limiting block 22. A first groove 6 is formed in both the first U-shaped groove 11 and the second U-shaped groove 21, and the support shaft 5 is rotatably connected in the first groove 6. A second groove 7 is formed in the first U-shaped groove 11, located at the upper end of the first groove 6. A pressure plate 8 is fixedly connected in the second groove 7 for limiting the support shaft 5.

[0033] Preferably, the pressure plate 8 is fixedly connected to the second groove 7 by bolts.

[0034] When installing the limiting block, first place the support shaft 5 on the first limiting block 12 or the second limiting block 22 into the first groove 6, then place the pressure plate 8 into the second groove 7, and finally fix the pressure plate 8 in the second groove 7 with bolts. The pressure plate 8 and the first groove 7 simultaneously limit the support shaft 5, so that the support shaft 5 can only rotate in the first groove 7 without falling off.

[0035] Preferably, the first limiting block 12 and the second limiting block 22 are metal blocks with a main body that is approximately cuboid. A protruding structure 9 is provided at the heavy end to increase the weight, so that the heavy end can rotate downward under the action of gravity.

[0036] Preferred, such as Figure 1 As shown, the upper surface of the lower platform 3 is also provided with a third mounting groove 32, which is perpendicular to the first mounting groove 31. A corresponding third U-shaped groove 13 is provided on the lower template 1. There are four of each of the first mounting groove 31, the third mounting groove 32, and the first limiting block.

[0037] The lower surface of the upper plate 4 is also provided with a fourth mounting groove 42, which is perpendicular to the second mounting groove 41. The upper template 2 is provided with a corresponding fourth U-shaped groove 23. There are four of each of the second mounting groove 41, the fourth mounting groove 42, and the second limiting block 22.

[0038] The installation process and principle of the above embodiments are as follows:

[0039] When installing the mold, first lift the mold as a whole. At this time, due to the heavier protrusion structure 9 at the heavy end of the first limiting block 12 and the second limiting block 22, the heavy end will naturally rotate downward under the action of gravity. The heavy end of the first limiting block 12 can protrude from the lower surface of the lower template 1, and the light end of the second limiting block 22 can protrude from the upper surface of the upper template 2, forming a guide structure.

[0040] Then, using the heavy end of the first limiting block 12 protruding from the lower surface of the lower template 1 as a reference, the worker first aligns it with the first mounting groove 31 on the lower platform 3 of the equipment. After alignment, the mold is lowered, and the heavy end of the first limiting block 12 can just fit into the first mounting groove 31 to form a positioning. Then, the upper platform 4 of the equipment is lowered until the lower surface of the upper platform 4 contacts the light end of the second limiting block 22 and is pressed down further, so that the second limiting block 22 rotates slightly, while the lower surface of the upper platform 4 does not contact the upper surface of the upper template 2. Figure 4 As shown.

[0041] Next, a forklift is used to move the mold horizontally along the direction of the first mounting groove 31. When the mold moves to the designated position, the second limiting block 22 is exactly below the second mounting groove 41 of the upper plate 4. At this time, since the upper plate 4 is no longer pressing down on the overlapping second mounting groove 41 and the second limiting block 22, the lighter end of the second limiting block 22 will rotate again under its own weight and protrude from the upper plate 2 of the mold, and be engaged in the second mounting groove 41. Figure 5 As shown.

[0042] At this point, the positioning mechanism, which forms a rectangular coordinate system with the upper and lower parts of the mold perpendicular to each other, can accurately position the mold on the equipment platform. After positioning, the upper platen 4 of the equipment is lowered to press the upper template 2. Then, the connecting block between the upper and lower molds is removed, and T-bolts are used to fix the first mounting groove 31 and the first U-shaped groove 11, the second mounting groove 41 and the second U-shaped groove 21, the third mounting groove 32 and the third U-shaped groove 13, and the fourth mounting groove 42 and the fourth U-shaped groove 23 in pairs. This completes the rapid positioning and installation of the mold.

[0043] The above specific embodiments are only for illustrating the technical concept and structural features of this utility model, and are intended to enable those skilled in the art to implement them. However, the above content does not limit the protection scope of this utility model. Any equivalent changes or modifications made in accordance with the spirit and essence of this utility model shall fall within the protection scope of this utility model.
