Description

Technical Field

[0001] The utility model relates to the field of extrusion casting machines, in particular to a lightweight fixed die plate for a vertical extrusion casting machine. Background Art

[0002] The fixed platen of the vertical squeeze casting machine is a key component for the squeeze casting process. It not only provides a stable support platform for the casting mold, but also withstands alternating high-pressure heavy loads and thermal shocks during the squeeze casting process. When the squeeze casting machine is closed, the molten metal in the mold cavity is squeezed by high pressure, and the surface and internal structure of the fixed platen are under huge pressure. The degree of deformation of the fixed platen directly affects the accuracy of the casting. On the other hand, due to the heavy weight of the fixed platen, it is necessary to consider both reducing its weight and its ability to resist extrusion deformation during the design stage. Therefore, the optimized design of the fixed platen of the vertical squeeze casting machine is particularly important to ensure its performance, efficiency and stability of the squeeze casting process.

[0003] At present, the fixed platen of the vertical squeeze casting machine is mostly a box-type cast iron or steel casting. With the further improvement of the clamping force of the vertical squeeze casting machine, the volume of the mold, the movable platen and the fixed platen is also getting larger and larger. If the fixed platen is designed according to the usual box-type structure, it will inevitably increase the weight of the fixed platen, increase the difficulty of the casting process of the fixed platen, and cause a large amount of material waste. Therefore, it is urgent to design a fixed platen with balanced structural rigidity, good load-bearing and heat-forming performance, and lightweight structure. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a lightweight fixed platen for a vertical extrusion casting machine. The overall scheme of the fixed platen adopts a special lightweight structure and integrates the functions of collecting sewage, facilitating the positioning and installation of the mold, and facilitating the rapid transportation of the fixed platen.

[0005] The specific scheme of the utility model is as follows: a M-shaped cavity is opened inside the fixed template and structural features such as a water receiving trough, a mold trolley bridge, a T-slot, a positioning ring mounting hole, and a hoisting hole are integrated. The water receiving trough is an annular groove, located at the edge of the top surface of the fixed template, and is used to collect sewage during the process of spraying the mold release agent on the mold; the mold trolley bridge is a set of parallel beam structures spanning above the water receiving trough, for the wheels of the mold trolley to pass through; the T-slot is located on the inner side of the water receiving trough, and is used to fix the mold; the positioning ring mounting hole is a countersunk hole, located at the center of the top surface of the fixed template, and is used to position the mold; there are four hoisting holes, located at the four corners of the side of the fixed template, for realizing the rapid hoisting and transportation of the fixed template. The four hoisting holes are symmetrically arranged on the vertical reinforcing ribs of the fixed template to ensure that the four corners of the fixed template are evenly stressed during the hoisting process to prevent distortion or deformation. At the same time, the rectangular stability is better, which can ensure that the fixed template remains stable during the hoisting process and reduce safety accidents caused by shaking or bumping.

[0006] The utility model has the following advantages:

[0007] (1) Compared with the conventional box-type fixed template, the utility model significantly reduces the overall weight of the fixed template by designing a cross-shaped cavity structure inside the bottom surface of the fixed template, making the template more convenient to install and transport. At the same time, the cross-shaped cavity structure is equivalent to a reinforcing rib structure, and the anti-deformation ability and strength of the fixed template are also significantly improved;

[0008] (2) The fixed mold plate is integrated with a water receiving trough structure to ensure that the release agent on the mold can flow into the water receiving trough, preventing sewage from dripping onto the equipment or working area and causing equipment failure;

[0009] (3) A set of parallel mold trolley bridges are integrated above the water tank. The operator can push the mold trolley onto the bridge and move it to the designated position through the bridge to install, replace or maintain the mold, which greatly improves work efficiency and safety and reduces the labor intensity and risk of the operator.

Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0021] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchanged where appropriate, so as to describe the embodiments of the present invention described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0022] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0023] A preferred embodiment is listed below, and the present invention is described more clearly in conjunction with the accompanying drawings.

[0024] like Figure 1 and Figure 2 As shown, the fixed mold plate 1 of the utility model has a fixed mold plate top surface 10, and the fixed mold plate top surface 10 and the bottom surface of the movable mold plate 2 are respectively fixedly installed with the fixed mold and the movable mold, and the fixed mold and the movable mold are joined to form a mold cavity, and the bottom surface 13 of the fixed mold plate is connected to the injection system 3 of the vertical extrusion casting machine;

[0025] The fixed mold plate 1 integrates a water receiving trough 4, a mold trolley bridge 9, a T-slot 6, a positioning ring mounting hole 5, a mounting hole 7 and a lifting hole 8. Figure 3 As shown, a crisscross cavity structure 11 is provided inside the fixed template.

[0026] The water receiving trough 4 is located at the edge of the top surface 10 of the fixed mold plate and is in the shape of an annular groove. When the mold is sprayed with a release agent, part of the release agent drips or flows due to excessive or uneven spraying. The water receiving trough 4 can effectively prevent the sewage from dripping directly onto the equipment or working area, thereby reducing equipment failures or quality problems that may be caused by sewage pollution.

[0027] like Figure 4 As shown, the mold trolley bridge 9 spans over the water tank 4 and is a set of parallel beam structures. The surface of the beam is flat and smooth, and the spacing of the beam structure is the same as the wheelbase of the mold trolley wheels, ensuring that the mold trolley wheels can pass smoothly, transfer the mold to be replaced to the designated position on the top surface 10 of the fixed mold plate, and then install, replace or maintain the mold. Compared with the traditional hoisting or fork-mounted mold changing method, the mold trolley bridge 9 is used in conjunction with the mold trolley to improve the efficiency and safety of mold changing and reduce the labor intensity and risk of operators.

[0028] The T-slot 6 consists of a transverse groove 61 and a vertical groove 62; the transverse groove 61 is located on the inner side of the water receiving tank 4, and the vertical groove 62 is located above the transverse groove 61 and is connected to the transverse groove 61. The T-slot 6 cooperates with a clamp or bolt with a similar T-shaped cross-section to achieve accurate positioning and fixing of the mold.

[0029] The positioning ring mounting hole 5 is a countersunk hole located in the central area of ​​the top surface 10 of the fixed mold plate, and its diameter matches the outer diameter of the mold fixed mold positioning ring;

[0030] The fixed template mounting hole 7 is circular and located on the bottom surface 13 of the fixed template, and is used to fix the position of the fixed template 1; the surface of the fixed template mounting hole 7 is smooth and has no burrs or sharp edges;

[0031] There are four hoisting holes 8, which are symmetrically arranged on the vertical reinforcing ribs of the fixed template 1, ensuring that the four corners of the fixed template 1 are evenly stressed during the hoisting process to prevent twisting or deformation. At the same time, the rectangular shape has better stability and reduces the bumping of the fixed template 1 during the hoisting process.

[0032] like Figures 5 to 8 As shown, the interior of the fixed mold plate 1 is a cross-shaped cavity structure 11, which includes 8 blind hole structures and 8 vertically arranged rib structures. The cross-shaped cavity structure 11 reduces the overall weight of the fixed mold plate, while increasing the contact area between the mold and the air, reducing the mold temperature, and ensuring the stability of the casting process; at the same time, the cross-shaped cavity structure, as a reinforcing rib structure, can effectively improve the anti-deformation ability and structural strength of the mold plate, and ensure the stability and precision of the fixed mold plate during the extrusion casting process;

[0033] The positioning ring mounting hole 5 is located at the center of the crisscross cavity structure 11;

[0034] The fixed die plate 1 further comprises four guide post holes 12 which are symmetrically distributed and penetrate vertically, and the guide posts of the vertical extrusion casting machine pass through the guide post holes 12 .

[0035] The utility model has the following advantages:

[0036] (1) Compared with the conventional box-type fixed template, the utility model significantly reduces the overall weight of the fixed template by designing a cross-shaped cavity structure inside the bottom surface of the fixed template, making the template more convenient to install and transport. At the same time, the cross-shaped cavity structure is equivalent to a reinforcing rib structure, and the anti-deformation ability and strength of the fixed template are also significantly improved;

[0037] (2) The fixed mold plate is integrated with a water receiving trough structure to ensure that the release agent on the mold can flow into the water receiving trough, preventing sewage from dripping onto the equipment or working area and causing equipment failure;

[0038] (3) A set of parallel mold trolley bridges are integrated above the water tank. The operator can push the mold trolley onto the bridge and move it to the designated position through the bridge to install, replace or maintain the mold, which greatly improves work efficiency and safety and reduces the labor intensity and risk of the operator.

[0039] Unless otherwise specifically stated, the relative arrangement, numerical expressions and numerical values ​​of the parts and steps described in the embodiment do not limit the scope of the utility model. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to the actual proportional relationship.

In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0040] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure.

Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0041] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present utility model; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0042] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
