[0046] Referring to Figures 1-7 The utility model provides a microwave drying device for lost mould, including microwave generating device, still including box 100, microwave generating device sets up on the box 100, and the box 100 has drying space 110, box cover 120 rotationally sets up on the box 100, and the box cover 120 opens or closes drying space 110 after rotation, tray 200 slidingly sets up in drying space 110, and tray 200 enters or leaves drying space 110 after sliding, and tray 200 is used to place lost mould, and tray 200 has interval with the bottom of drying space 110.
[0047] In the embodiment, the microwave generating device is installed on the box 100. The microwave generating device can generate microwaves to heat and dry the objects in the drying space 110. The box cover 120 is connected with the box 100 through rotation, which can realize the opening and closing of the drying space 110. The tray 200 can slide in the drying space 110, which is convenient for placing and taking the lost mould on the tray 200. When placing or taking the lost mould, the tray 200 is pulled out of the drying space 110 for placement, and after placement, the tray 200 is pushed into the drying space 110 to dry the lost mould on the tray 200. After the lost mould is dried, the tray 200 is pulled out of the drying space 110, which is convenient for the operator to take the lost mould.
[0048] The microwave drying method can directly act on the inside of the lost mould, greatly improves the drying efficiency, and shortens the drying period. For the same lost mould, compared with the ordinary drying method which needs 3-4 days, the microwave drying only needs 10-15 minutes to complete. The box 100 and the box cover 120 form a relatively closed drying space 110, which reduces heat loss and improves energy utilization.
[0049] Further, the tray 200 includes a main body 210 slidingly arranged in the drying space 110, and the length direction of the main body 210 is parallel to the direction of entering or leaving the drying space 110. A plurality of support bars 220 are arranged on the main body 210 in sequence along the length direction of the main body 210, and the support bars 220 have intervals therebetween. The plurality of support bars 220 are used to support the lost mould.
[0050] In the embodiment, when the lost mould is placed, the support bars 220 collectively support the lost mould, and because there are intervals between the support bars 220, the microwaves can pass through the intervals between the support bars 220 after being reflected by the inner wall of the box 100 and contact the bottom of the lost mould.
[0051] The arrangement of the plurality of support bars 220 can more stably support the lost form and prevent it from deforming or shifting during the drying process. The spacing between the support bars 220 not only facilitates the full contact of microwaves with the bottom of the lost form, improving the uniformity and efficiency of drying, but also facilitates the discharge of water vapor from the bottom of the lost form.
[0052] Further, the box body 100 has a moisture discharge port 130 for communicating the drying space 110 with the outside.
[0053] In this embodiment, during the drying process, the moisture evaporated from the lost form can be discharged to the outside through the moisture discharge port 130, thereby maintaining a relatively low humidity in the drying space 110, which is conducive to improving the drying efficiency. By discharging the moisture, potential damage to the internal structure of the box body 100 and the microwave generating device can also be reduced, prolonging the service life of the equipment.
[0054] Further, the control device 300 is arranged on the box body 100, and the control device 300 is used to control the output frequency of the microwave generating device; and the temperature display 400 is arranged on the box body 100, and the temperature display 400 is used to display the temperature in the drying space 110.
[0055] In this embodiment, the control device 300 can flexibly adjust the output frequency of the microwave generating device according to different lost form materials, sizes, and initial moisture contents, etc., to realize personalized drying solutions, improve the drying effect and quality, and the control device 300 can refer to the control device 300 of a microwave oven, which will not be described here. The temperature display 400 allows the operator to intuitively understand the temperature in the drying space 110, facilitating timely detection of problems and making corresponding adjustments.
[0056] Further, the main body 210 has two, the two main bodies 210 are parallel to each other, the two ends of the support bar 220 are arranged on the two main bodies 210 respectively, and the first protrusion 230 has two, which are arranged on the two ends of the two main bodies 210 away from each other respectively; the slide 140 has two, which are arranged on the two sides of the drying space 110 respectively, the first protrusion 230 is slidingly arranged in the slide 140, and the main body 210 is slidingly arranged in the drying space 110 through the first protrusion 230 and the slide 140; the baffle 150 is arranged on the side of the slide 140 close to the box cover 120, the baffle 150 is located on the sliding path of the first protrusion 230, and the baffle 150 is used to block the first protrusion 230 from sliding out of the slide 140.
[0057] In the actual device structure of the embodiment, the two parallel main bodies 210 build the main framework of the tray 200, and the support bars 220 are firmly connected to the two main bodies 210 at both ends, thereby jointly building a complete bearing structure. Each main body 210 protrudes a first protrusion 230 at the end far away from the other main body 210. The inner walls on both sides of the drying space 110 are carefully processed to form two corresponding slides 140, and the first protrusion 230 is sized to fit the slide 140, thereby not only ensuring that the first protrusion 230 can slide smoothly in the slide 140, but also providing strong support for the main body 210 by the first protrusion 230.
[0058] During installation, the first protrusion 230 is placed in the slide 140. During operation, the tray 200 is pulled to make the first protrusion 230 slide in the slide 140. When the tray 200 is pulled out of the drying space 110, the baffle 150 blocks the first protrusion 230 to prevent the first protrusion 230 from being completely separated from the slide 140 due to excessive pulling, thereby facilitating normal use next time.
[0059] Further, the slide 140 has a sliding space 141 and a mounting opening 142, the first protrusion 230 enters the sliding space 141 through the mounting opening 142, and further includes two positioning support plates 160, which are arranged on the sides of the two slides 140 close to each other, and the positioning support plates 160 are arc-shaped; the second protrusion 240 has two, which are arranged at the two ends of the two main bodies 210 far away from each other, and the second protrusion 240 abuts against the positioning support plate 160 after the first protrusion 230 enters the sliding space 141.
[0060] In the embodiment, the slide 140 has a sliding space 141 for accommodating the sliding of the first protrusion 230, and a mounting opening 142 for the first protrusion 230 to enter the sliding space 141. The mounting opening 142 facilitates the installation and disassembly of the first protrusion 230, thereby facilitating the maintenance and replacement of the tray 200. The positioning support plate 160 can support the second protrusion 240, and the slide 140 and the positioning support plate 160 support the first protrusion 230 and the second protrusion 240 respectively, thereby jointly supporting the support plate, which is conducive to improving the stability of the tray 200. The positioning support plate 160 is arc-shaped, which can provide better guidance and support when the second protrusion 240 abuts against it, thereby making the position of the tray 200 more accurate during drying.
[0061] Further, the end of the second protrusion 240 far away from the main body 210 does not enter the sliding space 141, and the first protrusion 230 and the second protrusion 240 are both cylindrical, and the diameter of the first protrusion 230 is smaller than that of the second protrusion 240.
[0062] In the embodiment, the second protrusion 240 is away from the end of the main body 210 and does not enter the sliding space 141, which can avoid the influence of the baffle 150 on the second protrusion 240 during the sliding of the tray 200, make the setting position of the second protrusion 240 more flexible, and increase the slidable range of the tray 200. The diameter of the first protrusion 230 is smaller than that of the second protrusion 240, which can avoid the interference of the positioning support plate 160 on the first protrusion 230 during the sliding of the tray 200. The first protrusion 230 and the second protrusion 240 are both cylindrical, which not only facilitates the positioning of the second protrusion 240 by the arc-shaped positioning support plate 160, but also facilitates the rotation of the tray 200 around the axis of the first protrusion 230, so that the second protrusion 240 can be away from the arc-shaped space of the positioning support plate 160.
[0063] Further, the baffle 150 is rotationally arranged on the slide 140, and after the baffle 150 is rotated, the baffle 150 is located in or away from the sliding path of the first protrusion 230.
[0064] In the embodiment, the baffle 150 can be flexibly rotated according to actual needs. If it is required to allow the first protrusion 230 to slide, i.e., not to block the first protrusion 230, the baffle 150 is rotated to be away from the sliding path of the first protrusion 230. At this time, the tray 200 can be directly pulled out from the drying space 110 without being taken out from the installation opening 142. Through the rotational arrangement of the baffle 150, the convenience of replacing the tray 200 is improved, the operation time and manpower are saved, and the operation is more flexible and variable to adapt to different working conditions and requirements.
[0065] Further, the baffle 150 has a first through hole 151, the slide 140 has a second through hole 143, the axis of the first through hole 151 coincides with the axis of the second through hole 143 after the baffle 150 is rotated to the sliding path of the first protrusion 230, and the device further comprises an insert 500 which is slidingly arranged in the second through hole 143 and slides along the axis direction of the second through hole 143. After the insert 500 slides into the first through hole 151, the insert 500 is used to prevent the baffle 150 from rotating.
[0066] In the embodiment, the insert 500 can slide along the axis direction of the second through hole 143. When the insert 500 slides into the first through hole 151, the insert 500 can block the baffle 150 to prevent it from rotating. Through the cooperation of the insert 500 with the first through hole 151 and the second through hole 143, the position of the baffle 150 can be reliably fixed to ensure its stability when it is required to block the sliding of the first protrusion 230, and the safety and reliability of the device are improved.
[0067] Further, the elastic member 600 is arranged on the baffle 150 and the slide 140 respectively at two ends, and the elastic member 600 is used to provide the force for the baffle 150 to rotate to the sliding path of the first protrusion 230.
[0068] In the embodiment, when the baffle 150 is not on the sliding path of the first protrusion 230, the elastic member 600 is in a stretching or compressing state and stores elastic potential energy. When the baffle 150 is not subjected to other external force, the elastic member 600 releases the elastic potential energy, and the elastic force generated thereby automatically rotates the baffle 150 to the sliding path of the first protrusion 230, so as to facilitate the plug-in member 500 to slide into the first through hole 151.
[0069] When the tray 200 needs to be taken out, the plug-in member 500 only needs to be slid out of the first through hole 151, without other additional operations, which is beneficial to improve the convenience of operation.
[0070] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application but not limit the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application, and all of them should be covered in the scope of the claims of the present application.
