Description

Technical Field

[0001] This utility model relates to the technical field of parts casting processing, specifically to a metal casting drying device. Background Technology

[0002] Metal castings are obtained by pouring molten metal into a mold and allowing it to cool and solidify. Metal castings offer several advantages: they typically achieve higher dimensional accuracy and lower surface roughness; their mechanical properties are superior to sand castings—for the same alloy, tensile strength can be increased by an average of approximately 25%, yield strength by an average of approximately 20%, and corrosion resistance and hardness are also significantly improved; and they require little or no sand, generally saving 80-100% of molding materials.

[0003] Common castings include irregular plate-shaped parts, machine block blanks, crankshaft blanks, cylinder blocks, etc. After cooling, they need to be cleaned, dried, and coated with anti-rust oil or maintenance oil. Chinese patent application CN202222023742.9, "A Metal Workpiece Drying Box", discloses a metal workpiece drying box. Common drying boxes on the market are similar to the drying box body described in the above patent. Several air-permeable support plates or support nets are set in the drying cavity at vertical intervals. The castings are then placed on the support nets, which can dry all the castings placed in the cavity at the same time. However, there are still the following shortcomings: water on the castings above will drip down onto the castings below, affecting the drying time of the castings below, thus affecting the overall drying time. Therefore, it is necessary to design a metal casting drying device. Utility Model Content

[0004] To address the aforementioned technical problems, the purpose of this utility model is to overcome the issue in the prior art where water from the upper casting drips onto the lower casting, increasing drying time.

[0005] To achieve the above objectives, this utility model provides a metal casting drying device, comprising: a drying chamber body and several sets of water guiding units arranged vertically on the inner wall of the drying chamber body, wherein an air inlet is provided at the bottom of the inner cavity of the drying chamber body and an air outlet is provided at the top of the inner cavity of the drying chamber body.

[0006] Each water guiding unit includes a water guiding box mounted on the inner wall of the drying oven body, with its bottom inclined and its open top horizontal. The open top of each water guiding box has a flange that protrudes inward. A parts frame can be placed on the flange at the top of each water guiding box. The inclined bottom of each water guiding box has at least one vent, and the edge of the vent protrudes upward to form a water blocking part. A water-blocking component is mounted on the bottom of the water guiding box, located directly above the corresponding vent and spaced apart from the vent.

[0007] Preferably, the bottom of the water guide box is provided with a drain port, and a connecting pipe is connected to the flange on the lower water guide box to communicate with the drain port on the adjacent upper water guide box.

[0008] Preferably, the water-blocking component includes a water-blocking part parallel to the bottom of the water guide box and at least one support part fixedly connected to and fixedly disposed on the bottom of the water guide box.

[0009] Preferably, the water guiding unit further includes a horizontal first support arm fixedly mounted on one side wall of the inner cavity of the drying oven body and a second support arm fixedly mounted on the side wall of the inner cavity of the drying oven body opposite to the first support arm. The bottom of the water guiding box is in contact with the first support arm and the second support arm. The water guiding box is detachably connected to the second support arm through a mounting component.

[0010] Preferably, the mounting component is a mounting bolt, the second support arm is provided with a threaded portion that matches the mounting bolt, and the bottom of the water guide box is provided with a mounting portion through which the mounting bolt passes.

[0011] Preferably, a handle is fitted on the outer wall of the water receiving box.

[0035] When it is necessary to clean the water guide box 4, the mounting part 15 can be removed to separate the water guide box 4 from the first support arm 13 and the second support arm 14 for cleaning.

[0036] The mounting component 15 is a mounting bolt, the second support arm 14 is provided with a threaded portion that matches the mounting bolt, and the bottom of the water guide box 4 is provided with a mounting portion through which the mounting bolt passes.

[0037] Loosen the mounting bolts to remove the water guide box 4; the operation is simple and convenient.

[0038] A handle 16 is fitted on the outer wall of the water receiving box 10.

[0039] A closed edge strip 17 is fixedly mounted on the bottom wall edge of the part frame 6. A protrusion 18 is mounted on the lower surface of each corner of the edge strip 17. Several of the protrusions 18 can move to the inside of the flange 5 so that the edge strip 17 and the flange 5 fit together.

[0040] When the part frame 6 is placed elsewhere, the protrusion 18 can act as a support foot; when the part frame 6 is placed on the flange 5, the protrusion 18 is located inside the flange 5, which can prevent the part frame 6 from slipping off the water guide box 4 and improve safety.

[0041] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0042] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0043] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
