Description

Technical Field

[0001] This utility model relates to the field of casting mold technology, specifically to a multi-directional limiting mold structure. Background Technology

[0002] In the field of metal mold casting, the precision and stability of the mold structure directly determine the dimensional compliance rate of the product and the service life of the mold. In traditional mold structures, a sliding pair is used between the mold base plate and the side mold module to guide and limit the movement of the side mold module. However, there is a lack of guiding and limiting mechanisms between the side mold module and the column, which leads to the following problems:

[0003] 1. Insufficient mold precision: Traditional sliders only restrict the unidirectional movement of the module and cannot simultaneously control multiple degrees of freedom (such as displacement in the height direction and rotational deviation). During the casting process, the dynamic stress generated by the filling and solidification of molten metal will cause slight displacement of the module, especially the lifting or sinking in the height direction, resulting in product dimensions exceeding tolerances and failing to meet high precision requirements.

[0004] 2. Severe wear of the limiting structure: Traditional molds rely on direct contact between the column and the module back plate for limiting. The contact surface has a large friction area and the material hardness is insufficient, making it prone to wear under high temperature and high pressure conditions. As the number of times the mold is used increases, the limiting gap gradually widens, further aggravating dimensional fluctuations and shortening the mold life.

[0005] 3. Deformation and failure of the module backplate: As the main load-bearing component in traditional structures, the backplate is subjected to uneven thermal and mechanical stresses under the impact of the composite mold and molten metal. Due to the lack of multi-directional rigid support, the backplate is prone to plastic deformation, leading to module misalignment and loss of product size control.

[0006] 4. Single limiting direction: Traditional structures lack active limiting design in the height direction, relying solely on module self-weight or simple mechanical constraints to prevent lifting, which is insufficient to cope with the thermal expansion effects during casting. When the mold closes, local stress concentration can easily cause slight lifting or tilting, further reducing the mold closing accuracy.

[0007] 5. Low maintenance efficiency: The wear and repair of the column and back plate requires disassembly of the entire mold structure, which is time-consuming and difficult to guarantee the consistency of the repair, resulting in a long mold repair cycle and high cost.

[0008] The aforementioned problems lead to a significant decrease in product qualification rate, an increase in scrap rate, and a shortened mold lifespan during long-term use of traditional molds. Summary of the Invention

[0009] The purpose of this invention is to address the shortcomings of existing technologies by providing a multi-directional limiting mold structure. This multi-directional limiting mold structure can achieve multi-directional coordinated limiting, reduce wear, facilitate maintenance, stably control product dimensions, and extend service life.

[0010] The objective of this utility model is achieved through the following solution:

[0011] A multi-directional limiting mold structure includes a mold base plate, a bottom mold module, a side mold module, and columns vertically fixed at the four corners of the mold base plate. The bottom mold module is fixedly installed on the mold base plate, and the side mold module is located between two columns. The mold base plate is fixed with a first slide rail and a second slide rail. The bottom of the side template of the side mold module is fixed with a first slide bar and a second slide bar that slide and engage with the first slide rail and the second slide rail, respectively. The upper inner sides of the columns on both sides are fixed with a third slide rail and a fourth slide rail, respectively. The upper sides of the side template are fixed with a third slide bar and a fourth slide bar that slide and engage with the third slide rail and the fourth slide rail, respectively.

[0012] Preferably, both the first slide rail and the second slide rail have an L-shaped cross section and a guide limiting port. The guide limiting ports of the first slide rail and the second slide rail are arranged opposite to each other. The first slide bar and the second slide bar slide in cooperation with the guide limiting ports of the first slide rail and the second slide rail, respectively.

[0013] Preferably, a first limiting block and a second limiting block are fixed on both sides of the outer end of the bottom mold module, and a third limiting block and a fourth limiting block are fixed on the inner bottom side of the side mold module corresponding to the first limiting block and the second limiting block.

[0014] Preferably, the first slide rail, the second slide rail, the first slide bar, the second slide bar, the third slide rail, the fourth slide rail, the third slide bar, the fourth slide bar, the first limiting block, the second limiting block, the third limiting block, and the fourth limiting block are all made of wear-resistant alloy steel.

[0015] Preferably: the first slide rail and the second slide rail are fixedly installed on the mold base plate by bolts, the third slide rail and the fourth slide rail are fixedly installed on the column by bolts, the first slide bar, the second slide bar, the third slide bar, the fourth slide bar, the third limit block, and the fourth limit block are fixedly installed on the side template by bolts, and the first limit block and the second limit block are fixedly installed on the bottom mold module by bolts.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. By using the sliding cooperation of slide rails and slide bars, the mold size can be controlled in multiple directions, the degree of freedom of the mold module can be controlled, the positional error of the mold can be reduced, the product size can be stably controlled, and the size fluctuation problem caused by the single limit of traditional molds can be solved.

[0018] 2. By using slide rails and slide bars, non-contact setting of mold modules can be achieved, which can reduce the wear rate of the mating surfaces of mold modules, extend the service life of molds, and reduce the risk of mold failure caused by mechanical wear.

[0019] 3. By cooperating with the limiting blocks of the bottom mold module and the side mold plate, the freedom of the mold module in the front and rear directions is controlled, eliminating the back plate limiting structure of the traditional mold, eliminating the influence of back plate deformation on the mold closing accuracy, and stably controlling the product size.

[0020] 4. Based on the coordinated limiting of the slide rail on the column and the slide bar of the side template, combined with the bidirectional guide rail structure of the slide rail on the mold base plate and the slide bar of the side template, the degree of freedom in the height direction of the mold module is controlled together, effectively suppressing the lifting displacement of the mold module during the mold closing process.

[0021] 5. By using slide rails and sliders to restrict the freedom of the mold modules, and with the detachable connection method, the mold can be quickly interchanged and repaired, which greatly shortens the grinding time and improves the grinding efficiency.

[0022] 6. The slide rails and slide bars are made of high-hardness, wear-resistant and other superior materials, which can greatly reduce the number of mold repairs.

[0023] In summary, multi-directional coordinated limiting is achieved through the cooperation of slide rails and sliders, eliminating the need for direct mold contact limiting. This non-contact limiting avoids the mechanical wear caused by direct contact in traditional molds, significantly extending mold lifespan. Compared to traditional molds, the use of slide rails and sliders increases limiting in multiple directions, constraining degrees of freedom, reducing positional accuracy errors in mold modules, and enabling precise control of mold position, improving product yield, and stable control of product dimensions.

[0029] like Figure 1-5As shown, a multi-directional limiting mold structure includes a mold base plate 100, a bottom mold module 200, a side mold module, and columns 300 vertically fixed at the four corners of the mold base plate 100. The bottom mold module 200 is fixedly installed on the mold base plate 100. The side mold module is inserted into the opening after the top mold module and the bottom mold module 200 are closed. The top mold module, the bottom mold module 200, and the side mold module enclose a product forming cavity. The mold base plate 100 is fixed with a first slide rail 1 and a second slide rail 2. The bottom of the side template 400 of the side mold module is fixed with a first slide bar 3 and a second slide bar 4 that slide and cooperate with the first slide rail 1 and the second slide rail 2, respectively. The upper inner sides of the columns 300 on both sides are fixed with a third slide rail 5 and a fourth slide rail 6, respectively. The upper sides of the side template 400 are fixed with a third slide bar 7 and a fourth slide bar 8 that slide and cooperate with the third slide rail 5 and the fourth slide rail 6, respectively.

[0030] In this way, the horizontal degree of freedom of the side mold module is limited by the cooperation of the first slide rail, the second slide rail and the first slide bar and the second slide bar. The vertical degree of freedom of the side mold module is limited by the cooperation of the third slide rail, the fourth slide rail and the third slide bar and the fourth slide bar. This achieves positional constraint of the side mold module, improves mold closing accuracy, and solves the problem of dimensional fluctuation caused by the single limiting of traditional molds.

[0031] In this specific embodiment: the first slide rail 1 and the second slide rail 2 are both L-shaped cross sections and have guide limiting ports. The guide limiting ports of the first slide rail 1 and the second slide rail 2 are arranged opposite to each other. The first slide bar 3 and the second slide bar 4 are respectively slidably engaged with the guide limiting ports of the first slide rail 1 and the second slide rail 2.

[0032] In this way, the guide limiting port includes a horizontal guide surface and a vertical limiting surface. The lower surfaces of the first and second slide bars slide in cooperation with the horizontal guide surface, and the inner surfaces of the first and second slide bars slide in cooperation with the vertical limiting surface. This can guide and limit the movement of the side mold module, and also serve as a guide rail for the opening and closing of the side mold module.

[0033] In this specific embodiment: the bottom mold module 200 is fixed with a first limiting block 11 and a second limiting block 12 on both sides of its outer end, and the bottom inner side of the side mold 400 is fixed with a third limiting block 9 and a fourth limiting block 10 corresponding to the first limiting block 11 and the second limiting block 12.

[0034] In this way, when the mold is closed, the first limit block and the third limit block, as well as the second limit block and the fourth limit block, form a zero-clearance fit structure, eliminating displacement in the front and rear directions, solving the problem of easy deformation of traditional back plate limiters, controlling the degree of freedom of the mold module in the front and rear directions, and ensuring product size consistency.

[0035] In this specific embodiment: the first slide rail 1, the second slide rail 2, the first slide bar 3, the second slide bar 4, the third slide rail 5, the fourth slide rail 6, the third slide bar 7, the fourth slide bar 8, the first limiting block 11, the second limiting block 12, the third limiting block 9, and the fourth limiting block 10 are all made of wear-resistant alloy steel. The wear-resistant alloy steel can be SKD61, H13, or other materials.

[0036] In this specific embodiment: the first slide rail 1 and the second slide rail 2 are fixedly installed on the mold base plate 100 by bolts; the third slide rail 5 and the fourth slide rail 6 are fixedly installed on the column by bolts; the first slide bar 3, the second slide bar 4, the third slide bar 7, the fourth slide bar 8, the third limiting block 9, and the fourth limiting block 10 are fixedly installed on the side template 400 by bolts; and the first limiting block 11 and the second limiting block 12 are fixedly installed on the bottom mold module 200 by bolts. The detachable installation allows for easy replacement after wear, improving mold repair efficiency.

[0037] This metal mold casting mold structure is applicable to metal mold casting of aluminum alloys and non-ferrous metals.

Any modifications made to the present utility model by those skilled in the art without departing from the spirit of the present utility model shall fall within the protection scope of the present utility model.
