Description

Technical Field

[0001] This utility model relates to the field of casting and molding equipment technology, and in particular to a cover plate wax sealing device. Background Technology

[0002] In the process of silica sol precision casting, before coating the wax film with slurry to form a shell, a metal cover plate is needed to seal the mouth of the wax film to prevent the slurry from entering the interior of the wax film along the mouth, thus ensuring the casting effect of the subsequent castings.

[0003] In related technologies, because the cover plate seals the opening of the wax film, the cover plate also becomes coated with slurry during the wax film coating and shell-making process. When the cover plate needs to be reused, the slurry on the cover plate must be removed first. The existing solution uses tumbling polishing to remove the slurry on the cover plate. However, tumbling polishing not only generates a lot of dust, polluting the environment, but also has low cleaning efficiency and increases the labor intensity of employees. In addition, during tumbling polishing, the cover plate is subjected to impact force, which can easily deform the cover plate and affect subsequent use. Specifically, when the cover plate seals the opening of the wax film, due to the bending of the cover plate, it cannot seal the opening, allowing the slurry to enter the wax film through the gap between the cover plate and the opening, which can easily lead to sand inclusion defects in the casting. To solve the above problems, a processing solution of sealing wax on the surface of the cover plate is provided, so that the slurry adheres to the wax film outside the cover plate. When cleaning the slurry on the cover plate later, it is only necessary to melt the wax film with high temperature. Currently, there is no equipment for sealing wax on cover plates to meet the needs of large-scale wax sealing processing of cover plates.

[0004] Therefore, there is an urgent need to invent a cover plate sealing wax device to solve the above problems. Utility Model Content

[0045] To make the technical problem solved by this utility model, the technical solution adopted, and the technical effect achieved clearer, the technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0046] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0047] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0048] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0049] In the wax coating and shell-making process, because the cover plate seals the opening of the wax film, the cover plate also becomes coated with slurry during the coating process. When the cover plate needs to be reused, the slurry on the cover plate must be removed first. The existing solution uses tumbling polishing to remove the slurry from the cover plate. However, tumbling polishing not only generates a lot of dust, polluting the environment, but also has low cleaning efficiency and increases the labor intensity of employees. In addition, during tumbling polishing, the cover plate is subjected to impact force, which can easily deform the cover plate and affect subsequent use. Specifically, when the cover plate seals the opening of the wax film, if the cover plate bends, it may fail to seal the opening, allowing the slurry to enter the wax film through the gap between the cover plate and the opening, which can easily lead to sand inclusion defects in the casting. To solve the above problems, a processing solution of sealing wax on the surface of the cover plate is provided, so that the slurry adheres to the wax film outside the cover plate. When cleaning the slurry on the cover plate later, only the wax film needs to be melted at high temperature. Currently, there is no equipment for sealing wax on cover plates to meet the needs of large-scale wax sealing processing of cover plates.

[0050] Therefore, such as Figures 1-5 As shown, this embodiment provides a cover plate sealing device. The cover plate sealing device includes a receiving box 100, a heating mechanism 200, a transfer mechanism (not shown in the figure), and a stationary frame 300. The receiving box 100 has a first chamber 110 and a second chamber 120 that are isolated from each other. The second chamber 120 surrounds the outer periphery and bottom of the first chamber 110. The first chamber 110 is used to contain paraffin wax, and the second chamber 120 is used to contain a heat-conducting agent. Heat can be transferred between the first chamber 110 and the second chamber 120. The heating mechanism 200 is used to heat the heat-conducting agent. The transfer mechanism is used to clamp and transfer the cover plate 2000. The stationary frame 300 is installed at the receiving box 100 and is used to store the cover plate 2000 whose surface is coated with liquid paraffin wax.

[0051] This wax-sealing device consists of a first chamber 110 and a second chamber 120 isolated from each other within a housing 100. The second chamber 120 surrounds the outer periphery and bottom of the first chamber 110. Paraffin wax is placed in the first chamber 110, and a heat-conducting agent is placed in the second chamber 120. A heating mechanism 200 heats the heat-conducting agent in the second chamber 120. Heat transfer between the first and second chambers 110 achieves the heating of the paraffin wax in the first chamber 110, transforming solid paraffin wax into a liquid state. A stationary rack 300 is set at position 00. A transfer mechanism is used to clamp and transfer the cover plate 2000. The cover plate 2000 without liquid paraffin on its surface can be placed into the first chamber 110. The cover plate 2000 in the first chamber 110 is then transferred to the stationary rack 300. The stationary rack 300 stores the cover plate 2000 with liquid paraffin on its surface, allowing the liquid paraffin on the surface of the cover plate 2000 to cool into solid paraffin, thus completing the sealing process of the cover plate 2000. The sealing effect is good, the work efficiency is high, and it can meet the needs of large-scale sealing processes of cover plates 2000.

[0052] As an optional solution, the stationary frame 300 includes a supporting upright 320 and a suspension crossbar 310. The supporting upright 320 is connected to the upper end face of the receiving box 100 and extends upward in the vertical direction. The suspension crossbar 310 is connected to the supporting upright 320 and extends horizontally. The cover plate 2000 is provided with a through hole 2100, through which the suspension crossbar 310 passes. By dividing the stationary frame 300 into the supporting upright 320 fixed to the upper end face of the receiving box 100 and the suspension crossbar 310 connected to the supporting upright 320, the supporting upright 320 extends vertically, and the suspension crossbar 310 extends horizontally. By passing the suspension crossbar 310 through the through hole 2100 on the cover plate 2000, the cover plate 2000 can be suspended and fixed on the suspension crossbar 310. The structure is simple and provides a good stationary effect for the cover plate 2000.

[0053] In addition, in this embodiment, the transfer mechanism is a hook. The hook extends into the through hole 2100 on the cover plate 2000 to hang and fix the cover plate 2000. The operator drives the hook and the cover plate 2000 hung and fixed on the hook to move, so as to put the cover plate 2000 whose surface is not covered with liquid paraffin into the first chamber 110, and to transfer the cover plate 2000 in the first chamber 110 to the suspension crossbar 310.

[0054] In an optional embodiment, the cover plate sealing device further includes a control mechanism 400, which is communicatively connected to the heating mechanism 200. The control mechanism 400 is used to control the opening and closing of the heating mechanism 200. By using the communication connection between the control mechanism 400 and the heating mechanism 200, the control mechanism 400 can control the opening and closing of the heating mechanism 200, thus preventing the heating temperature of the heat-conducting agent by the heating mechanism 200 from becoming too high and improving the operational safety of the cover plate sealing device. It should be noted that in this embodiment, the control mechanism 400 can not only control the opening and closing of the heating mechanism 200, but also control the operating power of the heating mechanism 200, that is, the heating power of the heating mechanism 200 on the heat-conducting agent, to further improve operational convenience.

[0055] Specifically, the control mechanism 400 includes a first protective shell and a controller. The first protective shell is fixed to the outer wall of the housing 100, and the controller is stored in the first protective shell. The controller is used to control the opening and closing of the heating mechanism 200 and its operating power. The first protective shell is used to enhance the protection of the controller. The specific structure and control principle of the controller are existing technologies and will not be described in detail here.

[0056] As an optional solution, the cover sealing device also includes a detection mechanism 500, which is communicatively connected to the control mechanism 400. The detection mechanism 500 is used to detect the temperature of the paraffin wax in the first chamber 110 in real time. By setting the detection mechanism 500 to detect the temperature of the paraffin wax in the first chamber 110 in real time and communicating with the control mechanism 400, the detection mechanism 500 can transmit the detection information to the controller in the control mechanism 400. After receiving the detection information, the controller can control the opening and closing of the heating mechanism 200 and its specific operating power according to the detection information, further improving the automation level of the cover sealing device. It should be noted that in this embodiment, the detection mechanism 500 includes a temperature sensor and a second protective shell. The second protective shell is fixed on the receiving box 100, and the temperature sensor is located inside the second protective shell. The temperature sensor is communicatively connected to the controller, and the second protective shell is used to improve the protection of the temperature sensor. The specific structure and working principle of the temperature sensor are existing technologies and will not be described in detail here.

[0057] In this embodiment, the heating mechanism 200 includes a heating tube and a third protective shell. The third protective shell is fixed to the receiving box 100, and the heating tube is located inside the third protective shell, with a portion of the heating tube extending into the second chamber 120. The heating tube is used to heat the heat-conducting agent and is communicatively connected to the controller. The third protective shell is used to enhance the protection of the heating tube. The specific structure and working principle of the heating tube are existing technologies and will not be described in detail here.

[0058] To further improve the sealing efficiency of the cover plate 2000, the cover plate sealing device also includes a fan. The fan is positioned corresponding to the stationary rack 300, and it blows air onto the cover plate 2000 stored on the stationary rack 300. By using the fan to blow air onto the cover plate 2000 stored on the stationary rack 300, the surface airflow rate of the liquid paraffin coated on the surface of the cover plate 2000 can be increased, thereby increasing the cooling rate of the liquid paraffin and thus improving the sealing efficiency of the cover plate 2000.

[0059] In an alternative embodiment, the cover sealing device further includes a support bracket located in the first chamber 110 and immersed in liquid paraffin. The support bracket supports the cover plate 2000. By placing the support bracket in the first chamber 110 and immersing it in liquid paraffin, the cover plate 2000 is supported by the support bracket when it is immersed in the liquid paraffin. This avoids direct contact between the cover plate 2000 and the wall of the first chamber 110, solving the problem of damage to the first chamber 110 due to collision between the cover plate 2000 and the wall of the first chamber 110, and improving the protection of the first chamber 110.

[0060] Combination Figure 3 The specific structure of the receiving box 100 is described below. The receiving box 100 also includes a first control valve (not shown in the figure). The first chamber 110 has a first outlet 111, through which paraffin wax can be discharged. The first outlet 111 is connected to the first control valve, which controls the connection between the first outlet 111 and the outside world. By providing a first outlet 111 in the first chamber 110 and a first control valve connected to it, the first control valve controls the connection and disconnection between the first outlet 111 and the outside world, achieving the effect of freely controlling the discharge of paraffin wax from the first chamber 110 through the first outlet 111, facilitating the cleaning of the first chamber 110. It should be noted that in this embodiment, the first control valve is a butterfly valve. Butterfly valves have a simple structure, are easy to operate, and are convenient to install. In other embodiments, the first control valve can also be a ball valve, gate valve, or other types of valves; this embodiment does not impose specific limitations.

[0061] Furthermore, a guide slope 112 is provided at the lower end of the first chamber 110. The guide slope 112 extends downward, and the first outlet 111 is located at the lowermost end of the guide slope 112. When the first control valve opens the first outlet 111 to the outside, the paraffin wax in the first chamber 110 will flow along the guide slope 112 under its own gravity and be discharged from the first chamber 110 through the first outlet 111. The guiding effect of the guide slope 112 improves the discharge speed and efficiency of the paraffin wax in the first chamber 110 through the first outlet 111. It should be noted that in this embodiment, the horizontal slope of the guide slope 112 is 30°. In other embodiments, the horizontal slope of the guide slope 112 can be adjusted arbitrarily within the range of 10° to 60°, and this embodiment does not impose a specific limitation.

[0062] like Figure 3 As shown, the container 100 also includes a second control valve (not shown) and a third control valve (not shown). The second chamber 120 has a first inlet 121 and a second outlet 122. The heat transfer agent can be discharged into the second chamber 120 along the first inlet 121 and discharged from the second chamber 120 along the second outlet 122. The second control valve is connected to the first inlet 121 and is used to control the connection and isolation between the first inlet 121 and the outside. The third control valve is connected to the first inlet 121 and is used to control the connection and isolation between the second outlet 122 and the outside. By opening a first inlet 121 and a second outlet 122 in the second chamber 120, a second control valve is connected to the first inlet 121, controlling the connection and disconnection between the first inlet 121 and the outside world. Similarly, a third control valve is connected to the second outlet 122, controlling the connection and disconnection between the second outlet 122 and the outside world. This allows for free control of the heat transfer fluid entering the second chamber 120 through the first inlet 121 and freely controlling the discharge of the heat transfer fluid from the second chamber 120 through the second outlet 122. It should be noted that in this embodiment, both the second and third control valves are butterfly valves. Butterfly valves are simple in structure, easy to operate, and convenient to install. In other embodiments, the second and third control valves can also be ball valves, gate valves, or other types of valves; this embodiment does not impose specific limitations.

[0063] Furthermore, to further enhance the protection of the container 100, multiple downward-extending support legs 130 are spaced apart at the lower end of the container 100. These support legs 130 rest on the ground to isolate the container 100 from the ground. It should be noted that in this embodiment, four downward-extending support legs 130 are spaced apart at the lower end of the container 100, and all four support legs 130 abut against the ground to support the container 100. In other embodiments, the specific number of support legs 130 can be adjusted according to actual needs; this embodiment does not impose a specific limitation.

[0064] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
