Description

Technical Field

[0001] This utility model belongs to the field of investment casting technology, and more specifically, it relates to a drying device for investment casting mold shells. Background Technology

[0002] Investment casting, also known as lost-wax casting, includes processes such as wax pressing, wax trimming, tree assembly, slurry application, wax melting, pouring molten metal, and post-processing. Lost-wax casting involves creating a wax model of the part to be cast, then coating the wax model with clay slurry to form a clay model. After the clay model dries, it is placed in hot water to melt the inner wax model. The melted clay model is then removed and fired to form a ceramic mold. Once fired, a pouring gate is typically left during the clay model making process, through which molten metal is poured.

[0003] Based on the above, it has been found that the placement frame of the current drying equipment cannot be freely adjusted according to the height of the mold shell, which makes it unsuitable for mold shells of different heights and has certain limitations. Utility Model Content

[0004] To address the aforementioned technical problems, this disclosure relates to a drying device for investment casting mold shells. It solves the issue that current drying equipment cannot freely adjust the placement frame according to the height of the mold shell. By adjusting the structure, the device can freely adjust the placement frame according to the shell height. Furthermore, in actual production applications, investment casting mold shells come in various height specifications. The adjustable placement frame can flexibly adapt to shells of different heights, eliminating the need for specialized drying equipment or placement frames for different heights. This significantly improves the versatility and applicability of the equipment, reducing equipment investment costs for enterprises. The collection structure effectively prevents water vapor from condensing at the top of the equipment and dripping back onto the shell surface, preventing the shell from being re-wetted, disrupting the original uniform drying state, extending drying time, and thus ensuring consistent and high-quality drying results, thereby increasing the yield of finished mold shells.

[0038] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0039] Example 1: As shown in the attached document Figure 1 To be continued Figure 5 As shown:

[0040] This utility model provides a drying device for investment casting mold shells, including a shell 1 and an adjustment structure 2;

[0041] The equipment housing 1 has an internal cavity 101. A door 102 is hinged to the front end of the equipment housing 1. A support recess 201 is provided at the bottom of the internal cavity 101. A square groove 2011 is provided on the support recess 201. Fixed supports 202 are fixedly connected to the top two sides of the support recess 201. A connecting vertical rod 2021 is fixedly connected to the top of the fixed supports 202. A locking hole 2022 is provided at one outer end of the connecting vertical rod 2021. A sliding groove 2023 is provided on the opposite side of the connecting vertical rod 2021. A first... A placement plate 203 is connected to a connecting top plate 204 fixedly to the top of a connecting vertical rod 2021. Two sets of second placement plates 205 are provided between the first placement plate 203 and the connecting top plate 204. Fixed protrusions 2051 are fixedly connected to both ends of the second placement plates 205. Guide rails 2052 are fixedly connected to both sides of the fixed protrusions 2051. A reset groove 2053 is provided inside the fixed protrusion 2051. A sliding support hole 2054 is provided at the front end of the reset groove 2053. A spring 2055 is provided in the reset groove 2053. The reset groove 2053 also contains... A pressing protrusion 206 is provided, and a sliding connecting rod 2061 is fixedly connected to the midpoint of the pressing protrusion 206. The sliding connecting rod 2061 passes through the sliding support hole 2054 and is fixedly connected to the outer pull handle 2062. Locking pins 2063 are fixedly connected to the inner sides of both ends of the pull handle 2062. The locking pins 2063 are fitted into the locking holes 2022. By pulling the pull handles 2062 on both sides, the pull handles 2062 move, thereby causing the locking pins 2063 to disengage from the locking holes 2022, and thus the position of the second placement plate 205 can be adjusted. After the position is adjusted, Select the corresponding locking socket 2022. At this time, release the pull handle 2062. When the pull handle 2062 moves, it drives the pressing protrusion 206 to press the spring 2055 in the reset groove 2053 through the sliding link 2061, causing the spring 2055 to undergo elastic deformation. When the pressure is lost, the spring 2055 elastically pushes the pressing protrusion 206 to move. The pressing protrusion 206 drives the pull handle 2062 to reset through the sliding link 2061. The pull handle 2062 drives the locking pin 2063 to be inserted into the locking socket 2022, thereby completing the adjustment.

[0042] Example 2: Based on Example 1, wherein, as Figure 2As shown, a support 103 is fixedly connected to one side of the equipment housing 1. Supporting angle plates 1031 are fixedly connected to both ends of the bottom of the support 103. A hot air blower 1032 is fixedly installed on the top of the supporting angle plate 1031. An air duct 1033 is fixedly connected to the air outlet of the hot air blower 1032. The air duct 1033 passes through the equipment housing 1 and is fixedly connected to the U-shaped pipe 1034 inside. An exhaust port 1035 is fixedly installed on the U-shaped pipe 1034. At the same time, the U-shaped pipe 1034 is fixedly installed on the inner side wall of the equipment housing 1 by a fixing buckle 1036. Through the setting of the U-shaped pipe 1034, hot air is blown out in three directions, which accelerates the drying efficiency of the shell.

[0043] Example 3: Based on Example 1, wherein... Figure 5 As shown, the top of the inner cavity 101 is provided with a collection structure 3, which includes a guide member 301 and a collection cylinder 302. The guide member 301 is fixedly connected to the top of the inner cavity 101, and the collection cylinder 302 is provided at the bottom of the guide member 301. Fixed support plates 303 are fixedly connected to both sides of the top of the connecting top plate 204. The two ends of the fixed support plate 303 are respectively provided with a guide rod 3031 and a double-acting screw 3032. One end of the double-acting screw 3032 passes through the fixed support plate 303 and is fixedly connected to the outer rotating handle 3033. A fixed arc plate 304 is fixedly provided on the outer side of the collection cylinder 302. The two ends of the fixed arc plate 304 are fixedly connected with extension protrusions 3041. The extension protrusions 3041 are respectively provided with guide holes 3042 and threaded holes 3043. By setting the guide 301, the steam collected at the top can be directed to the bottom of the guide 301 and finally condense into water droplets that fall into the collecting cylinder 302. When the collecting cylinder 302 is full, the bidirectional lead screw 3032 is rotated by rotating the handle 3033 in the opposite direction. The bidirectional lead screw 3032 is engaged with the threaded hole 3043 on the extension protrusion 3041. However, the extension protrusion 3041 on the other side is guided at the upper limit of the guide rod 3031. Thus, the bidirectional lead screw 3032 drives the two sets of fixed arc plates 304 to move away from each other, thereby releasing the clamping of the collecting cylinder 302 and allowing it to be removed. When fixing, simply rotate the handle 3033 to move the two sets of fixed arc plates 304 towards each other through the bidirectional lead screw 3032, thereby clamping the collecting cylinder 302.

[0044] The specific usage and function of this embodiment are as follows:

[0045] In this invention, by pulling the two handles 2062, the locking pin 2063 is disengaged from the locking hole 2022, thereby adjusting the position of the second placement plate 205. After adjusting the position, the corresponding locking hole 2022 is selected. At this time, the handles 2062 are released. When the handles 2062 move, they drive the pressing protrusion 206 to press the spring 2055 in the reset groove 2053 through the sliding link 2061, causing the spring 2055 to undergo elastic deformation. When the pressure is released, the spring 2055 elastically pushes the pressing protrusion 206 to move. The pressing protrusion 206 drives the handles 206 through the sliding link 2061. 2. Reset: Pull handle 2062 drives locking pin 2063 to be inserted into locking hole 2022, thereby completing the adjustment. It can be freely adjusted according to the shell height, and can flexibly adapt to shells of various heights. There is no need to specially equip drying equipment or placement frames of different specifications for shells of different heights, which greatly improves the versatility and applicability of the equipment and reduces the equipment investment cost of enterprises. Through the setting of guide component 301, the steam collected at the top can be accumulated to the bottom of guide component 301, and finally condensed into water droplets falling into collection cylinder 302. This can effectively prevent water vapor from condensing at the top of the equipment and dripping back onto the shell surface, thus preventing the shell from being wetted again.
