Description

Technical Field

[0001] This invention relates to the field of experimental equipment technology, specifically to a small, portable experimental device for testing the flowability of low-melting-point materials. Background Technology

[0002] Material flowability is an important performance indicator in fields such as materials science and engineering, and casting technology. In particular, in teaching experiments and process research on low-melting-point materials (such as paraffin-based composite materials), accurate and convenient assessment of their flowability is of great significance for understanding material properties and optimizing process parameters.

[0003] Currently, most teaching experimental equipment for testing the flowability of low-melting-point materials is based on fixed, single-function measuring devices. Common equipment typically employs a single flow channel model (such as only serpentine or only spiral flow channels), making it difficult to conduct comparative studies on the effects of different flow channel types on flowability on the same experimental platform, thus limiting the diversity and depth of experimental teaching. Furthermore, such equipment is often large and difficult to move, with separate heating and insulation modules, resulting in low temperature control precision, poor experimental repeatability, and high energy consumption.

[0004] The existing equipment also has several structural inconveniences: for example, the gates are mostly designed with conical funnels, which can easily lead to difficulties in demolding the wax and cleaning; the mold system and heating part are mostly designed separately, which causes heat to dissipate quickly and affects the stability of the experimental temperature; the overall equipment lacks integrated and portable design, which is not conducive to flexible use in various teaching occasions (such as classrooms, laboratories, on-site demonstrations, etc.).

[0005] Therefore, there is an urgent need for a highly integrated, portable experimental device for low-melting-point material flowability that can support comparisons of multiple flow channel types and has precise temperature control, in order to meet the higher requirements of modern engineering education and practical research for experimental flexibility, accuracy and safety. Summary of the Invention

[0006] This invention provides a small, portable experimental device for testing the flowability of low-melting-point materials to solve the above-mentioned problems.

[0007] This invention provides a small, portable experimental device for testing the flowability of low-melting-point materials, comprising a mold system, a heating and insulation module, a base, and a housing.

[0008] The mold system includes a replaceable runner mold, a mold cover plate covering the runner mold, and a pouring cup for pouring material into the runner mold.

[0009] The flow channel mold has flow channels for material flow, and the flow channel mold is configured to provide at least two different geometric flow channel types for selection.

[0010] The heating and heat preservation module includes a heating furnace for heating materials and a heat preservation furnace for maintaining the temperature of the materials.

[0011] The equipment base is provided with a receiving structure for embedding and installing the heating and heat preservation module, and a mounting part for installing the mold system;

[0012] The equipment box is divided into at least two storage spaces to accommodate the mold system and the heating and insulation module, respectively.

[0013] The experimental equipment mainly consists of four parts: mold system, heating and insulation module, equipment base and equipment box.

[0014] The mold system includes a replaceable runner mold, a mold cover plate covering the runner mold, and a pouring cup for pouring molten material into the runner mold. The runner mold is machined with channels (i.e., runners) for material flow, and the runner mold is designed to be replaceable as a whole, allowing users to select and install mold plates with different runner geometries according to experimental needs, thereby enabling comparative experiments on flowability under at least two different runner types.

[0015] The heating and heat preservation module is set up independently of the mold system and includes a heating furnace for heating the solid experimental material to a molten state and a heat preservation furnace for maintaining the molten material at a constant temperature before pouring.

[0016] The equipment base is a plate-like structure with a flat upper surface. Its interior or surface is provided with specialized receiving structures (such as grooves or mounting positions) for securely embedding and fixing the aforementioned heating furnace and holding furnace. Simultaneously, the upper surface of the equipment base also has a mounting section for installing and fixing the aforementioned mold system, ensuring that the mold system can be stably placed on the base during experiments.

[0017] The equipment case is a storage container with a cabinet body, its interior divided into at least two independent storage compartments by partitions or design. One compartment is used to house the mold system, and the other is used to house the heating and insulation module and the equipment base. This compartmentalized storage method allows all major components to be neatly placed inside the case, facilitating transportation and storage and achieving equipment portability.

[0018] During use, users can remove each component from the equipment box, assemble the heating and insulation module and the required flow channel mold on the equipment base, and carry out heating, pouring and observation. After the experiment, it can be disassembled and stored back in the equipment box.

[0019] This embodiment achieves flexible switching of flow channel types through replaceable flow channel molds, integrates heating and heat preservation functions through an embedded base, and achieves overall portability through a dedicated equipment box, thus constructing a comprehensive experimental platform that is multifunctional, easy to use, and easy to move.

[0020] In one alternative implementation, the at least two different geometric flow channel types include any two or more of the following: serpentine flow channels, spiral flow channels, and meander flow channels.

[0021] By providing these flow channel types with significant geometric differences, the apparatus in this embodiment can support studies on the effects of flow channel tortuosity, frequency of flow direction changes, and overall layout on the flow front advancement, filling capacity, and final flow length of low-melting-point materials (such as a mixture of paraffin and stearic acid). This design greatly enriches the experimental content and meets the teaching and research needs for comparative studies of material flow behavior.

[0022] In one alternative embodiment, the runner mold is configured such that the total length of the serpentine runner is 2500 mm, the total length of the spiral runner is 2177 mm, and the total length of the meander runner is selected from one or more of 1754 mm, 2018 mm, and 2320 mm.

[0023] In one alternative embodiment, the cross-sectional diameter of the flow channel is one or more of 5 mm, 7 mm, or 10 mm.

[0024] In one alternative embodiment, the pouring cup has a split structure and its depth is configured to be 85 mm.

[0025] The pouring cup adopts a split structure. Specifically, the main body of the pouring cup consists of two symmetrical halves, which can be connected together by simple snaps, hinges, or other openable methods, allowing it to be separated or opened from the side. In the closed state, the split pouring cup forms a complete funnel-shaped cavity inside, which is used to receive and guide the molten material into the runner mold below.

[0026] Furthermore, the cavity depth of this split-type pouring cup is configured to be 85 mm. This depth is designed to provide sufficient static head for low-melting-point materials such as liquid wax, thereby ensuring that the material has an appropriate pouring speed and sufficient pressure to smoothly fill the runner during the initial pouring stage, while the depth is controlled within a reasonable range to facilitate operation and subsequent cleaning.

[0027] The main advantage of the split structure is that after the experiment, once the material inside the pouring cup and at the entrance of the connected runner has solidified, the two halves of the pouring cup can be easily opened, allowing the solidified material to be easily removed. This greatly facilitates demolding and cleaning of residual material, solving the problem of difficult demolding of traditional one-piece conical funnels.

[0028] In one alternative embodiment, the mold cover is made of a transparent, high-temperature resistant material, and the mold cover is provided with an observation window and length scale markings.

[0029] In one optional embodiment, the equipment base includes a heat insulation layer and a heating plate stacked sequentially from bottom to top, and the receiving structure includes a square groove and a circular groove formed on the equipment base, which are respectively used to embed the heating furnace and the heat preservation furnace.

[0030] In one alternative embodiment, the mold system, the equipment base, and the heating and insulation module are detachably connected by bolts and wing nuts.

[0031] In one optional embodiment, the equipment box includes a box body and a box door. The interior of the box body is divided into upper and lower storage spaces, each storage space having dimensions of 600mm × 450mm × 245mm. The overall external dimensions of the equipment box are 610mm × 455mm × 510mm.

[0032] In one optional embodiment, the heating furnace operates at a temperature range of 10°C to 300°C and has a rated power of 2kW; the heat preservation furnace operates at a temperature range of 10°C to 200°C and has a rated power of 0.5kW. Attached Figure Description

[0049] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0050] Material flowability is an important performance indicator in fields such as materials science and engineering, and casting technology. In particular, in teaching experiments and process research on low-melting-point materials (such as paraffin-based composite materials), accurate and convenient assessment of their flowability is of great significance for understanding material properties and optimizing process parameters.

[0051] Currently, most teaching experimental equipment for testing the flowability of low-melting-point materials is based on fixed, single-function measuring devices. Common equipment typically employs a single flow channel model (such as only serpentine or only spiral flow channels), making it difficult to conduct comparative studies on the effects of different flow channel types on flowability on the same experimental platform, thus limiting the diversity and depth of experimental teaching. Furthermore, such equipment is often large and difficult to move, with separate heating and insulation modules, resulting in low temperature control precision, poor experimental repeatability, and high energy consumption.

[0052] The existing equipment also has several structural inconveniences: for example, the gates are mostly designed with conical funnels, which can easily lead to difficulties in demolding the wax and cleaning; the mold system and heating part are mostly designed separately, which causes heat to dissipate quickly and affects the stability of the experimental temperature; the overall equipment lacks integrated and portable design, which is not conducive to flexible use in various teaching occasions (such as classrooms, laboratories, on-site demonstrations, etc.).

[0053] Therefore, there is an urgent need for a highly integrated, portable experimental device for low-melting-point material flowability that can support comparisons of multiple flow channel types and has precise temperature control, in order to meet the higher requirements of modern engineering education and practical research for experimental flexibility, accuracy and safety.

[0054] The following is combined Figures 1 to 5 The following describes embodiments of the present invention.

[0055] According to an embodiment of the present invention, a small portable low-melting-point material flowability testing device is provided, comprising a mold system, a heating and insulation module, an equipment base 9, and an equipment box 6. The mold system includes a replaceable runner mold 1, a mold cover plate 2 covering the runner mold 1, and a pouring cup 3 for pouring material into the runner mold 1. The runner mold 1 has runners for material flow, and the runner mold 1 is configured to provide at least two different geometric runner types for selection. The heating and insulation module includes a heating furnace 4 for heating the material and a insulation furnace 5 for maintaining the material temperature. The equipment base 9 is provided with a receiving structure for embedding and installing the heating and insulation module, and a mounting part for installing the mold system. The equipment box 6 is internally divided into at least two storage spaces for respectively accommodating the mold system and the heating and insulation module.

[0056] The experimental equipment mainly consists of four parts: a mold system, a heating and insulation module, an equipment base 9, and an equipment box 6.

[0057] The mold system includes a replaceable runner mold 1, a mold cover plate 2 covering the runner mold 1, and a pouring cup 3 for pouring molten material into the runner mold 1. The runner mold 1 is machined with channels (i.e., runners) for material flow, and the runner mold 1 is designed to be replaceable as a whole, allowing users to select and install mold plates with different runner geometries according to experimental needs, thereby realizing flowability comparison experiments under at least two different runner types.

[0058] The heating and heat preservation module is set up independently of the mold system and includes a heating furnace 4 for heating the solid experimental material to a molten state, and a heat preservation furnace 5 for maintaining the molten material at a constant temperature before pouring.

[0059] The equipment base 9 is a plate-like structure with a flat upper surface. Its interior or surface is provided with a special receiving structure (such as a groove or mounting position) for securely embedding and fixing the heating furnace 4 and the holding furnace 5 thereon. At the same time, the upper surface of the equipment base 9 is also provided with a mounting part for installing and fixing the mold system thereon, so that the mold system can be stably placed on the base during the experiment.

[0060] The equipment case 6 is a storage container with a box-like structure, its interior divided into at least two independent storage spaces by partitions or design. One space is used to house the mold system, and the other space is used to house the heating and insulation module and the equipment base 9. This compartmentalized storage method allows all major components to be neatly placed inside the case, facilitating transportation and storage and achieving equipment portability.

[0061] During use, users can remove each component from the equipment box 6, assemble the heating and insulation module and the required flow channel mold 1 on the equipment base 9, and carry out heating, pouring and observation. After the experiment, it can be disassembled and stored back in the equipment box 6.

[0062] This embodiment achieves flexible switching of flow channel type through replaceable flow channel mold 1, integrates heating and heat preservation functions through embedded base, and achieves overall portability through dedicated equipment box 6, thus constructing a multifunctional, easy-to-use and easy-to-move comprehensive experimental platform.

[0063] In one embodiment, at least two different geometric flow channel types include any two or more of the following: serpentine flow channel, spiral flow channel, and meander flow channel.

[0064] In this embodiment of the experimental equipment, the replaceable flow channel mold 1 is specifically configured as a set of independent mold plates. This set of mold plates includes at least two plates with different flow channel geometries, which are selected from a set of serpentine flow channels, spiral flow channels, and meander flow channels.

[0065] For example, in a specific configuration, two flow channel mold plates can be prepared: one with a continuous serpentine flow channel with multiple 180-degree turns; and the other with a spiral flow channel that expands outward from the center. Users can choose to install either one during experiments to test the material flowability under either serpentine or spiral flow channel conditions.

[0066] In another, more comprehensive configuration, three flow channel mold plates can be prepared, each featuring a serpentine flow channel, a spiral flow channel, and a U-shaped flow channel. The U-shaped flow channel refers to a configuration where the flow channels are arranged in multiple concentric rectangular loops. This allows users to freely choose to install any one of these types or conduct comparative experiments using different flow channel types, depending on their experimental design.

[0067] By providing these flow channel types with significant geometric differences, the apparatus in this embodiment can support studies on the effects of flow channel tortuosity, frequency of flow direction changes, and overall layout on the flow front advancement, filling capacity, and final flow length of low-melting-point materials (such as paraffin mixtures). This design greatly enriches the experimental content and meets the teaching and research needs for comparative studies of material flow behavior.

[0068] In one embodiment, the runner mold 1 is configured such that the total length of the serpentine runner is 2500 mm, the total length of the spiral runner is 2177 mm, and the total length of the zigzag runner is selected from one or more of 1754 mm, 2018 mm, and 2320 mm.

[0069] In this embodiment, the specific design of the runner mold 1 meets the following dimensional configuration:

[0070] When the runner mold 1 provides a serpentine runner, the total length of the serpentine runner is set to 2500 mm.

[0071] When the runner mold 1 provides a spiral runner, the total length of the spiral runner is set to 2177 mm.

[0072] When the flow channel mold 1 provides a U-shaped flow channel, the total length of the U-shaped flow channel is configured to be selectable from one or more of the three values: 1754 mm, 2018 mm, and 2320 mm. This means that various U-shaped flow channel mold plates with different total lengths can be prepared for the user to choose according to the amount of experimental material or the expected flow distance.

[0073] The aforementioned length parameters were determined through theoretical calculations and simulation analysis optimization, based on material flow characteristics, overall mold plate size constraints, and typical requirements of teaching experiments. Fixed serpentine and spiral flow channel lengths facilitate standardized experimental comparisons, while the multiple length options provided by the U-shaped flow channel increase experimental flexibility and research variables.

[0074] In one embodiment, the cross-sectional diameter of the flow channel is one or more of 5 mm, 7 mm, or 10 mm.

[0075] In this embodiment, the runner formed on the runner mold 1 has a circular cross-sectional shape, and the diameter of the circle is configured to be selectable from 5 mm, 7 mm, or 10 mm. This means that multiple mold plate versions with different runner diameters can be prepared for each geometric runner shape (e.g., serpentine, spiral, or meander).

[0076] In practical configurations, three different diameter mold plates (5mm, 7mm, and 10mm) can be provided for the same flow channel type (such as a serpentine flow channel). When conducting experiments, users can select not only the geometry of the flow channel but also its cross-sectional area, thereby studying the influence of the flow cross-sectional dimensions on material flowability. For example, the difference in flow length of the same material can be compared between serpentine flow channels of the same length with diameters of 5mm and 10mm.

[0077] This multi-diameter configuration significantly increases the variables in experiments and the depth of research. Smaller diameters (e.g., 5 mm) increase flow resistance, making them suitable for testing materials with good flowability or studying flow behavior under high resistance; larger diameters (e.g., 10 mm) have lower flow resistance, making it easier to observe the filling process of materials with slightly poorer flowability.

[0078] In one embodiment, the pouring cup 3 has a split structure and its depth is configured to be 85 mm.

[0079] In this embodiment, the pouring cup 3 adopts a split structure. Specifically, the main body of the pouring cup 3 consists of two symmetrical halves, which can be connected together by simple snaps, hinges, or other openable methods, thereby allowing them to be separated or opened from the side. In the closed state, the split pouring cup 3 forms a complete funnel-shaped cavity inside, which is used to receive and guide the molten material into the runner mold 1 below.

[0080] Furthermore, the cavity depth of the split pouring cup 3 is configured to be 85 mm. This depth is designed to provide sufficient static pressure head for low-melting-point materials such as liquid wax, thereby ensuring that the material has an appropriate pouring speed and sufficient pressure to smoothly fill the runner during the initial pouring stage, while the depth is controlled within a reasonable range to facilitate operation and subsequent cleaning.

[0081] The main advantage of the split structure is that after the experiment, when the material inside the pouring cup 3 and the inlet of the runner connected to it solidifies, the two halves of the pouring cup 3 can be easily opened, so as to easily remove the solidified material handle, which greatly facilitates demolding and cleaning of residual material, and solves the problem of difficult demolding of traditional one-piece conical funnel.

[0082] In one embodiment, the mold cover plate 2 is made of a transparent, high-temperature resistant material, and the mold cover plate 2 is provided with an observation window and length scale markings.

[0083] In this embodiment, the mold cover plate 2 is made of a transparent, high-temperature resistant material. This allows the cover plate to maintain good transparency and structural integrity even when subjected to certain temperatures during the experiment (e.g., contact with or proximity to a mold and material at 65°C to 85°C), without significant deformation or fogging. Simultaneously, the cover plate covers the entire flow channel mold 1, and its transparency allows the operator to directly and in real-time observe the flow front position, flow state, and subsequent solidification process of the molten material inside the flow channel, thus achieving visualization of the experimental process.

[0084] Furthermore, the mold cover plate 2 is also equipped with an observation window and length scale markings. In a specific design, the observation window is a transparent area on the main body of the cover plate corresponding to the flow path below. The length scale markings are either directly printed or engraved next to the transparent area on the surface of the cover plate, or integrated into the cover plate without obstructing the view. These markings are arranged along the expected flow direction of the flow channel, and their zero point is usually aligned with the beginning of the flow channel (gate position), allowing the operator to directly read the real-time flow distance or final flow length of the material by observing the scale position corresponding to the flow front under the transparent cover plate, thereby quickly and conveniently obtaining key experimental data.

[0085] By employing transparent, high-temperature resistant materials and integrating graduated markings, the mold cover plate 2 in this embodiment not only protects the flow channels and prevents excessive heat loss, but more importantly, transforms the traditionally "black box" flow process into an intuitive and quantitatively observable experimental step, greatly improving the teaching demonstration effect and the efficiency and accuracy of experimental data acquisition. Specifically, circular grooves with a diameter of 4mm and a depth of 2mm are evenly distributed along the flow channel at 50mm intervals on each flow channel mold 1, serving as length graduated markings.

[0086] In one embodiment, the equipment base 9 includes a heat insulation layer 7 and a heating plate 8 stacked sequentially from bottom to top, and the receiving structure includes a square groove and a circular groove formed on the equipment base 9, which are used to embed the heating furnace 4 and the heat preservation furnace 5, respectively.

[0087] In this embodiment, the equipment base 9 is a composite structure comprising a thermal insulation layer 7 and a heating plate 8 stacked sequentially from bottom to top. The thermal insulation layer 7, located at the bottom, is typically made of foam material, asbestos board, or other materials with low thermal conductivity, and is used to prevent heat loss to the tabletop or environment below. The heating plate 8, tightly attached above the thermal insulation layer 7, is typically a metal plate (such as an aluminum plate), and its function is to provide a uniform and stable heat conduction foundation for the mold system placed on it, thereby slowing down the cooling rate of the mold and materials during the experiment.

[0088] Furthermore, the receiving structure formed on the equipment base 9 specifically includes a square groove and a circular groove. The shape and size of the square groove match the bottom of the heating furnace 4, used to securely embed the heating furnace 4 and restrict its horizontal movement. The shape and size of the circular groove match the bottom of the holding furnace 5, used to securely embed the holding furnace 5. Through this precisely matched embedded installation, the heating furnace 4 and the holding furnace 5 are integrated with the equipment base 9 as a whole, which not only improves the structural compactness and stability of the equipment, but more importantly, this close contact facilitates the efficient transfer of heat from the heating furnace 4 and the holding furnace 5 to the equipment base 9 and the mold system above, while reducing unnecessary heat loss to the surrounding environment, thereby improving the temperature uniformity and control accuracy of the entire experimental system.

[0089] In one embodiment, the mold system, the equipment base 9, and the heating and insulation module are detachably connected by bolts and wing nuts.

[0090] In this embodiment, the fixed connections between the mold system, the equipment base 9, and the heating and insulation module are all detachably connected using bolts and wing nuts. This connection method is used throughout the assembly and fixing process of the equipment.

[0091] Specifically, in the mold system, the mold cover plate 2 and the runner mold 1 are secured by using fully threaded bolts passing through pre-drilled holes at their corners, and then tightening a wing nut at the bottom. The connection between the sprue cup 3 and the mold system is achieved using extended fully threaded bolts, which pass sequentially through the mounting ears of the sprue cup 3, the mold cover plate 2, and the corresponding through holes on the runner mold 1, finally tightening a wing nut at the bottom of the runner mold 1, thus connecting the three components into one unit.

[0092] After the heating furnace 4 and the heat preservation furnace 5 are embedded in the square and round slots of the equipment base 9, they can be fixed to the base by bolts that are screwed upward from the bottom of the equipment base 9 and engaged with the mounting holes at the bottom of the furnace body, and by using wing nuts to lock them on the top of the equipment base 9.

[0093] The advantage of using a combination of bolts and wing nuts is that the wing nuts have a large wing-shaped structure that facilitates hand-tightening, allowing for tightening and loosening operations without the need for any additional tools (such as wrenches or screwdrivers) during the assembly of the entire equipment, replacement of the flow channel mold 1, and disassembly and cleaning after the experiment. This greatly improves the ease of use and efficiency of the equipment, and enhances its user-friendliness as a teaching device.

[0094] Considering that the runner mold 1 and the mold cover plate 2 are difficult to disassemble after the wax solidifies, two grooves are designed on both sides of the runner mold 1 to facilitate mold disassembly and easy movement of the entire mold system.

[0095] In one embodiment, the equipment box 6 includes a box body and a door. The interior of the box body is divided into upper and lower storage spaces, each with dimensions of 600mm×450mm×245mm. The overall external dimensions of the equipment box 6 are 610mm×455mm×510mm.

[0096] In one embodiment, the heating furnace 4 has an operating temperature range of 10°C to 300°C and a rated power of 2kW; the heat preservation furnace 5 has an operating temperature range of 10°C to 200°C and a rated power of 0.5kW.

[0097] In one embodiment, the small portable low-melting-point material flowability testing device also includes an electronic balance. This electronic balance is used during the experiment preparation stage to accurately weigh the required mass of the low-melting-point solid material (such as a mixture of paraffin and stearic acid) to ensure consistent material usage for each experiment, thereby guaranteeing the reliability and repeatability of the experimental results.

[0098] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by the appended claims.
