Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of metal casting, in particular to a general structure and method of a mold plate suitable for casting molding. BACKGROUND

[0002] In modern casting production, the molding line is the core production equipment. The molding machine completes the processes of sand filling, compacting, and mold lifting by installing a mold plate with a mold pattern, thereby manufacturing a sand mold. The mold plate is usually fixed on a special mold plate frame through positioning pins and bolts, and the mold plate frame is connected with the moving and static pressure plates of the molding machine.

[0003] At present, most casting factories usually configure multiple molding production lines in order to meet the diversified product demand. These production lines may be aimed at different castings, or come from different manufacturers and be built in different periods, so their specifications, tonnages and working areas are significantly different. The mold plate frames of different production lines have different size specifications, so that the mold plates and the mold patterns thereon cannot be used between different production lines.

[0004] This results in the fact that the casting enterprise must develop exclusive mold plates and mold plate frames for each production line, which significantly increases the initial hardware investment of new production line construction, and also leads to a large mold plate frame inventory. Each time a new casting is developed, multiple sets of mold plate frames for the mold plate of the new casting need to be repeatedly manufactured for all production lines, and the mold management and storage costs are high. Moreover, when the production plan needs to adjust the tasks between different production lines, the scheduling flexibility is very poor due to the non-interchangeability of the mold plates. When changing production, especially when changing different castings, the operator must perform tedious overall disassembly and installation operations of the mold plates and mold plate frames. This process is time-consuming and labor-intensive, which leads to prolonged equipment downtime and limits the flexible production mode of multiple varieties and small batches.

[0005] This inherent mode of "one line, one frame, and one plate" causes serious technical bottlenecks in production, which restricts production efficiency and economic benefits. SUMMARY

[0006] The present application provides a general structure and method of a mold plate suitable for casting molding, which realizes the generalization of the mold plate between different production lines through a connecting plate frame, thereby reducing various costs such as initial equipment investment, later development of new products, storage and management, etc.

[0026] Reference Figures 1 to 4 The general structure of the mold plate applicable to casting molding of the present invention is shown in the following embodiment: A general-purpose mold plate structure suitable for casting molding includes: a mold plate frame 100, a mold plate body 200, and a connecting plate frame 300.

[0027] The template frame 100 is in the shape of a frame, and the upper end of the template frame 100 is provided with a first template positioning structure 110 to form a first positioning area.

[0028] The template body 200 is flat and has a connecting structure for fixing the shape pattern. The shape pattern is fixed to the template body 200 through the connecting structure.

[0029] The connecting plate frame 300 is flat, and a second molded plate positioning structure 310 is provided on the upper side of the connecting plate frame 300 to form a second positioning area. The shape and size of the second positioning area match the shape and size of the molded plate body 200, and the molded plate body 200 is detachably installed in the second positioning area. The shape and size of the connecting plate frame 300 match the first positioning area, and the connecting plate frame 300 is detachably installed in the first positioning area.

[0030] In actual use of the universal mold plate system of this application for molding production, the molding pattern is fixed on the mold plate body 200. The mold plate body 200 is adapted to the mold plate frame 100 via the connecting frame 300, so that the mold plate body 200 and the mold plate frame 100 can be fixed together. The mold plate frame 100 provides a solid base for the mold plate body 200, ensuring that the pattern on the mold plate can evenly transmit pressure to the molding sand, producing a sand mold with uniform hardness. The connecting frame 300 is adapted to and connected to the mold plate frame 100, and the second mold plate positioning structure 310 achieves docking with the mold plate body 200, so that mold plates body 200 and mold plate frame 100 of different specifications can be used together. The universal mold plate system of this application enables molding machines and mold plate frames 100 of multiple specifications to adapt to the production of mold plates body 200 of different specifications, avoiding the increase of inventory of mold plate frames 100 of multiple specifications. When changing products, workers do not need to painstakingly disassemble the entire massive mold frame 100 from the machine; they only need to replace the mold plate body 200 and the connecting frame 300 inside the mold frame 100.

[0031] Enterprises no longer need to invest repeatedly in customizing dedicated template bodies 200 and template frames 100 for each production line. They only need to manufacture a set of universal connecting frames 300, which allows the template body 200 to be used on other compatible production lines. This greatly reduces initial equipment investment and subsequent new product development costs. At the same time, the types and quantities of templates in inventory can be significantly reduced, lowering warehousing and management costs.

[0032] In this embodiment, both the first mold plate positioning structure 110 and the second mold plate positioning structure 310 are groove-shaped. The mold plate body 200 is embedded in the second positioning area, and the connecting plate frame 300 is embedded in the first positioning area. The positioning and nesting of the mold plate frame 100, the mold plate body 200, and the connecting plate frame 300 are achieved through the corresponding groove structures.

[0033] In a further embodiment, a first positioning guide post 111 and a first positioning pin 112 are provided in the first positioning area. The first positioning guide post 111 and the first positioning pin 112 are arranged in pairs. The connecting plate frame 300 is provided with a first positioning guide hole 321 and a first pin hole corresponding to the first positioning guide post 111 and the first positioning pin 112, respectively. A second positioning guide post 311 and a second positioning pin 312 are provided in the second positioning area. The second positioning guide post 311 and the second positioning pin 312 are arranged in pairs. The molded plate body 200 is provided with a second positioning guide hole and a second pin hole corresponding to the second positioning guide post 311 and the second positioning pin 312, respectively.

[0034] In the assembly process of actual application, the guide post and guide hole structures are used to guide the plate body 200 and the connecting plate frame 300, as well as the plate frame 100 and the connecting plate frame 300, to facilitate installation, and the corresponding pin and pin hole structures are used to improve the installation accuracy.

[0035] In this embodiment, the mold frame 100 is a cuboid frame shape. The projections of the mold plate body 200 and the connecting frame 300 in the vertical direction are both rectangular. Correspondingly, the projections of the first positioning area and the second positioning area in the vertical direction are both rectangular. The cuboid frame shape of the mold frame 100 can be matched with existing molding machines. The pattern is fixed to the mold plate body 200 through the connecting structure to form the model structure such as the gating system and risers. Then, it is connected to the mold frame 100 through the connecting frame 300 and fixed on the molding machine, thereby pressing precise cavities and channels into the molding sand in the sand box. The connecting structure on the mold plate body 200 used to fix the pattern is an existing connecting structure, which will not be described in detail here.

[0036] In this embodiment, the thickness of the template body 200 is less than the thickness of the connecting frame 300, and the depth of the second positioning region is less than the thickness of the connecting frame 300. The lower end face of the template body 200 abuts against the bottom end face of the groove in the second positioning region.

[0037] The mold frame 100 is provided with a grid-structured support frame 120. The upper end of the support frame 120 has support parts arranged along the plane, which abut against the lower end face of the connecting frame 300 to provide uniform support. The support frame 120 supports the connecting frame 300 and the mold plate 200, thereby resisting the deformation of the mold plate itself under the huge molding pressure during the molding process, and ensuring that the working surface of the mold plate has uniformity and extremely high rigidity over the entire area.

[0038] In this embodiment, the thickness of the connecting plate frame 300 is greater than the depth of the first positioning area. To prevent the connecting plate frame 300 from protruding beyond the first positioning area of ​​the molded plate frame 100 and affecting the shape, the lower end edge of the connecting plate frame 300 is set as a stepped structure so that the edge of the connecting plate frame 300 can be fitted into the edge of the first positioning area. The middle part of the connecting plate frame 300 is aligned with the area where the support frame 120 is located. By replacing the support frame 120 with a corresponding height, the thickness of the connecting plate frame 300 is adapted so that the support frame 120 abuts against the lower end surface of the connecting plate frame 300.

[0039] The support frame 120 in this embodiment includes multiple longitudinal and transverse stiffeners in the shape of flat plates. The multiple longitudinal and transverse stiffeners are arranged in a crisscross pattern to form a grid structure, and the upper end surfaces of the longitudinal and transverse stiffeners form a support portion. The support frame 120 is a one-piece molded part.

[0040] In a further embodiment, in order to precisely control the temperature of the mold plate 200 and the pattern thereon, and to prevent the condensation of the cold core box sand core or certain adhesives on the mold plate 200, thereby avoiding mold sticking and surface defects of the sand mold, a heating pipe 130 is provided between the mold plate 200 and the mold frame 100. Specifically, the heating pipe 130 is arranged in a serpentine bend on the lower side of the mold plate 200 and the connecting frame 300, and the upper end of the support frame 120 is provided with a groove corresponding to the heating pipe 130, in which the heating pipe 130 is embedded.

[0041] In some other embodiments, to avoid the structure on the underside of the template body, the second template positioning structure is provided with a clearance hole that extends vertically through the frame. At least one of the support portions of the support frame extends along the edge of the clearance hole.

[0042] In other embodiments, when the thickness of the template body 200 is equal to the thickness of the connecting frame 300, the depth of the second positioning area is equal to the thickness of the connecting frame 300, that is, the second positioning area extends vertically through the connecting frame 300. In this embodiment, the connecting frame 300 is an annular flat plate shape, the lower end face of the template body 200 is flush with the lower end face of the connecting frame 300, the lower end face of the template body 200 abuts against the upper end of the support frame 120, the outer edge of the connecting frame 300 is embedded in the first positioning area, and a portion of the lower end face of the connecting frame 300 is located at the upper end of the support frame 120.

[0043] In this embodiment, the upper end of the mold plate frame 100 is provided with a sealing member 140 extending along a closed-loop path. The first positioning area is located within the area enclosed by the sealing member 140. A ventilation area is provided between the sealing member 140 and the first positioning area, and a plurality of ventilation holes 150 are arranged in the ventilation area. The sealing member 140 can prevent molding sand from intruding and abrading the mating interface between the mold plate body 200 and the mold plate frame 100, or between the connecting plate frame 300 and the mold plate frame 100.

[0044] In this embodiment, the upper edge of the mold frame 100 is provided with a groove, and the sealing member 140 is installed in the groove of the mold frame 100, surrounding the entire first positioning area, that is, the installation area between the mold plate body 200 and the connecting frame 300. The sealing member 140 may be, but is not limited to, an elastic rubber or polyurethane sealing strip. When the sand box is fixed and locked to the mold frame 100, the sealing strip will be moderately compressed, thereby forming a tight sealing ring.

[0045] During the compaction molding process, the molding sand is rapidly compressed, and the air between the sand particles is violently squeezed out. The vent holes 150 provide a rapid escape channel for this air, preventing insufficient hardness due to ineffective compaction of the molding sand, or defects such as micro-expansion, cracks, and pores. The vent holes 150 are arranged between the sealing member 140 and the first positioning area, and the vent holes 150 are provided with a grid that does not extend beyond the upper end of the mold frame 100. The vent holes 150 penetrate the mold frame 100 vertically, and multiple vent holes 150 are evenly distributed in the planar area of ​​the mold frame 100 to ensure that the total venting area is sufficient to allow air to escape instantly without generating back pressure.

[0046] In some other embodiments, the connecting plate frame 300 includes at least one edge pad and at least one positioning pad. The edge pad forms the outer edge of the connecting plate frame 300. The positioning pad forms the second type plate positioning structure 310.

[0047] Edge pads are adjustable or detachable and are provided on the outer edge of the connecting plate frame 300, so that the size of the connecting plate frame 300 in the corresponding direction can be adjusted, or the size can be changed by removing and replacing edge pads of different sizes, so as to adapt to the size of the first positioning area of ​​the plate frame 100.

[0048] Furthermore, the positioning pads can be adjusted and installed on or detachably installed on the connecting plate frame 300, thereby allowing the dimensions of the second positioning area to be set according to different specifications of the template body 200, improving the flexibility and applicability of the connecting plate frame 300. The adjustable structure of the connecting plate frame 300 can significantly reduce the inventory and cost of the connecting plate frame 300.

[0049] The adjustable connection structure or detachable and replaceable installation structure of the edge pad and the positioning pad can be achieved by using screws and slotted holes to lock them in different positions, or by using other existing adjustable or detachable connection methods, which will not be described in detail here.

[0050] Generally, the edge pads are arranged in pairs at opposite ends of the connecting plate frame 300, thereby keeping the connecting plate frame 300 and the molded plate frame 100 centrally aligned. Similarly, the positioning pads are installed in pairs on the connecting plate frame 300, thereby enabling the molded plate body 200 to be centrally aligned with the connecting plate frame 300 and the molded plate frame 100.

[0051] Reference Figure 5 This embodiment also provides a universal method for mold plates applicable to casting molding. A first-specification mold plate is adapted to a second-specification mold plate frame 100 via a connecting frame 300, replacing the second-specification mold plate originally matched to the second-specification mold plate frame 100 for production. The universal method for mold plates specifically includes the following steps: Step S100: Obtain first fitting information based on the shape and size of the first specification template; Step S200: Obtain the second fitting information based on the shape and size of the second specification plate; Step S300: A second positioning area is formed on the connecting plate frame 300 according to the first adaptation information, and a mating part matching the second specification plate frame 100 is formed on the connecting plate frame 300 according to the second adaptation information; Step S400: The first specification plate is detachably installed in the second positioning area, and the connecting plate frame 300 and the first specification plate are detachably installed in the second specification plate frame 100 through the docking part.

[0052] Before step S300, the first adaptation information and the second adaptation information are compared to determine whether a second positioning area and a docking part can be formed on the connecting plate frame 300.

[0053] Specifically, taking a rectangular plate as an example where the template body 200 is a rectangular plate and the template frame 100 is a cuboid frame structure, the first adaptation information in steps S100 and S200 includes the length, width, and thickness dimensions of the first specification template, and the second adaptation information includes the length, width, and thickness dimensions of the second specification template. When the length and width dimensions of the first specification template do not exceed the length and width dimensions of the second specification template, it is determined that a second positioning area and a mating part can be formed on the connecting frame 300.

[0054] Generally, this can be determined by the overlap of the projections of the first and second standard plates in the vertical direction. When the projection of the second standard plate completely covers the projection of the first standard plate, it is determined that a second positioning area and a mating part can be formed on the connecting frame 300. Conversely, if at least part of the projection of the first standard plate is not completely covered by the projection of the second standard plate, it is determined that a second positioning area and a mating part cannot be formed on the connecting frame 300.

[0055] The first adaptation information includes the thickness of the first specification plate, and the second adaptation information includes the thickness of the second specification plate. Generally, by comparing the first and second adaptation information, it is determined that when a second positioning area and a mating part can be formed on the connecting plate frame 300, the second specification plate is a larger specification plate than the first specification plate, that is, the thickness of the first specification plate does not exceed the thickness of the second specification plate.

[0056] According to an embodiment of the general structure of the mold plate applicable to casting molding in this application, in step S300, the connecting plate frame 300 forms the second positioning area by machining or forming a groove structure, and forms the mating part by machining or forming a stepped structure at the lower edge of the connecting plate frame 300.

[0057] In some embodiments, when the thickness of the first profile plate exceeds the thickness of the second profile plate, the shape and size of the support area corresponding to the support frame 120 in the second profile plate frame 100 are used as third adaptation information. This allows for comparison of the first and third adaptation information to determine whether a second positioning area and a mating portion can be formed on the connecting plate frame 300. The specific determination method is consistent with the method described above for comparing the first and second adaptation information. Simultaneously, the upper height of the support frame 120 in the second profile plate frame 100 also needs to be determined based on the thickness of the first profile plate.
