Abstract
Description
Technical Field
[0001] The embodiments of this utility model relate to the field of wax processing technology, specifically to a wax liquid level maintenance device. Background Technology
[0002] In investment casting production, it is necessary to attach the product gate to the runner (mold head). After the robot picks up the product, it first dips the product gate in molten wax, and then attaches the wax-dipped gate to the runner (mold head). However, as time goes by, the molten wax level will gradually decrease with production. In order to ensure that the depth of the bonded wax on each product gate is consistent, laser detection of the molten wax level is generally used. The robot will adjust the depth of the wax dipped in the molten wax according to the height of the molten wax level. However, because molten wax may be splashed during production, it may affect the accuracy of laser detection, which in turn affects the height of the robot's automatic adjustment, leading to an increased failure rate of the robot. Utility Model Content
[0003] To overcome the above-mentioned defects, the embodiments of this utility model provide a wax liquid level maintaining device, which solves the technical problem in the related technology that when the wax liquid level gradually decreases during the process of attaching the gate to the runner, the traditional laser detection of wax liquid level height will affect the laser detection accuracy due to the unavoidable wax splashing, which in turn leads to an increased failure rate of the robot arm.
[0004] According to one aspect, at least one embodiment of the present invention provides a wax liquid level maintaining device, comprising:
[0005] The working box has a liquid inlet, an overflow outlet and a liquid inlet, which are arranged sequentially from top to bottom. The liquid inlet is used to supply wax liquid into the working box so that the overflow outlet continuously discharges wax liquid.
[0006] For example, in a wax liquid level maintaining device provided in at least one embodiment of the present invention, the top of the working box is provided with the liquid inlet, and the liquid inlet is connected to the overflow port.
[0007] For example, in at least one embodiment of the present invention, a wax liquid level maintaining device further includes:
[0008] A wax supply box, wherein the working box is located inside the wax supply box, and the overflow port is connected to the wax supply box;
[0009] A waxing pump is installed inside the wax supply tank. The waxing pump has a wax inlet and a wax outlet. The wax outlet is connected to the liquid inlet. The waxing pump is used to pump the liquid wax in the wax supply tank into the working box.
[0010] For example, in a wax liquid level maintenance device provided in at least one embodiment of the present invention, a heating tube is provided in the wax supply box, and the heating tube is used to heat the wax liquid so as to keep the wax liquid in a liquid state.
[0011] For example, in a wax liquid level maintenance device provided in at least one embodiment of the present invention, there are several heating tubes arranged horizontally and all adjacent to the wax pump. The several heating tubes can keep the wax liquid around the wax inlet in a liquid state.
[0012] For example, in a wax liquid level maintaining device provided in at least one embodiment of the present invention, the heating tube is in the shape of a coil and is sleeved around the wax inlet, which can keep the wax liquid around the wax inlet in a liquid state.
[0013] For example, in a wax liquid level maintenance device provided in at least one embodiment of the present invention, a filter cylinder is detachably provided at the wax inlet, and a heating tube is sleeved around the filter cylinder for filtering impurities in the wax liquid.
[0014] For example, in a wax liquid level maintenance device provided in at least one embodiment of the present invention, the two ends of the filter cylinder are respectively detachably connected to the wax inlet and the inner wall of the wax supply box. The outer wall of the filter cylinder has a plurality of spirally arranged openings, and the openings are offset from the heating tube so that the wax liquid flows to the wax inlet through the openings and the filter cylinder.
[0015] For example, in a wax liquid level maintenance device provided in at least one embodiment of the present invention, a filter cylinder is detachably provided on the inner wall of the filter cylinder, the filter cylinder covers a plurality of the openings, and the filter cylinder can filter the wax liquid passing through the openings.
[0016] For example, in a wax liquid level maintenance device provided in at least one embodiment of the present invention, the wax supply box is further provided with a plurality of heating rods, the plurality of heating rods are arranged horizontally and are all arranged adjacent to the filter cylinder, and the plurality of heating rods can keep the wax liquid around the wax inlet in a liquid state.
[0017] The beneficial effects of the embodiments of this utility model are as follows:
[0018] Wax is continuously injected into the working chamber through the inlet, causing the wax level to rise until it overflows from the overflow tank. The wax in the working chamber is always overflowing, and the wax level remains constant at its highest position, forming a dynamic balance between inlet and overflow. This eliminates the need for real-time detection, thus eliminating the need for components such as laser detection, reducing the need for complex initial debugging, saving costs, and avoiding problems caused by splashing wax.
[0019] Furthermore, the depth to which the robotic arm picks up the wax each time is fixed, no longer depending on the wax consumption, but only on the position of the overflow port. This reduces the possibility of malfunctions that may occur due to the robotic arm constantly adjusting its insertion position. Attached Figure Description

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.
[0027] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."
[0028] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection 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.
[0029] 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.
[0030] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to 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.
[0031] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0032] like Figures 1-2 As shown, this invention illustrates a wax level maintaining device according to one embodiment of the present invention. It includes a working box 1 for feeding wax onto a product. From top to bottom, it has a feeding port 101, an overflow port 102, and an inlet 103. Specifically, the inlet 103 is generally located at the bottom of the working box 1 to facilitate a stable wax level rise and prevent splashing. The height of the feeding port 101 is greater than the height of the overflow port 102. As the amount of wax fed into the working box 1 increases until it continuously flows out of the overflow port 102, a robotic arm can then feed the product with the wax. From this point onward, the wax level will not change, meaning the displacement of the product by the robotic arm will no longer change. This eliminates the need for laser detection components and real-time monitoring to ensure consistent wax feeding depth, eliminating the need for complex initial adjustments, saving costs, and avoiding problems caused by splashing wax.
[0033] Furthermore, the depth to which the robotic arm picks up the wax each time is fixed, no longer depending on the wax consumption, but only on the position of the overflow port. This reduces the possibility of malfunctions that may occur due to the robotic arm constantly adjusting its insertion position.
[0034] like Figures 1-2 As shown, a liquid inlet 101 communicating with an overflow port 102 is opened on the top of the working box 1. The overflow port 102 can be opened on the side wall of the working box 1, so that the product can be extended into the working box 1 from the top and come into contact with the continuously flowing wax liquid surface at the height of the overflow port 102, so as to extend into a fixed displacement and meet the production requirements.
[0035] Alternatively, as a parallel embodiment, the two can be separate, with an overflow port 102 directly opened on the side wall, and a liquid inlet 101 can be opened at any position of the working box 1 above the overflow port 102, to ensure that the product can be inserted into the working box 1 and come into contact with the surface of the flowing wax liquid.
[0036] like Figure 1 As shown, in order to reduce material consumption and maintenance costs and enable the wax liquid to be recycled, the wax liquid discharged from the overflow port 102 can directly flow back to the wax supply tank 2 along the outer wall of the working box 1 or the connected pipeline. At the same time, the wax pump 3 submerged in the wax liquid in the wax supply tank 2 can pump the wax liquid from the wax inlet to the wax outlet, so that the wax liquid flows back into the working box 1, completing the automatic circulation. The overall structure is simple and easy to maintain. Furthermore, if after long-term use, it is found that the amount of circulating wax liquid decreases and cannot form circulation, and all of it remains in the working box 1 and cannot overflow, then new wax liquid can be added.
[0037] like Figure 1 As shown, a heating tube 4, which can be an electric heating tube, is further installed in the wax supply box 2 to heat the wax liquid so that the wax liquid remains in a liquid state. Before the device is operated, some solid wax blocks can be directly put into the wax supply box 2, and the heating tube 4 is powered on to heat the wax blocks to a liquid state, and then the operation of the product can begin.
[0038] Specifically, several heating tubes 4 can be arranged horizontally, with both ends of the heating tubes passing through the wax supply box 2 for easy connection to an external power source. At the same time, they are placed adjacent to the wax pump 3 to ensure that the wax around the wax inlet 301 remains liquid. Only wax with good fluidity can ensure the smooth circulation of the entire process and avoid the wax from being too viscous and unable to adhere evenly to the product gate.
[0039] In addition, such as Figures 3-4As shown, in a parallel embodiment, the heating tube 4 is modified into a coil shape and sleeved around the wax inlet 301, which can keep the wax liquid around the wax inlet 301 in a liquid state. A filter cylinder 5 is detachably installed at the wax inlet 301, one end of which is detachable from the wax inlet 301 and the other end is detachable from the inner wall of the wax supply box 2. The detachment relationship can be achieved by a flange to ensure sealing and to filter impurities in the wax liquid at the wax inlet 301, ensuring that the product picks up clean wax liquid, and at the same time facilitating the initial installation and disassembly. Afterwards, in order for the wax inlet 301 to draw wax liquid from the wax supply box 2, several spirally arranged openings 501 are opened on its outer wall, which are staggered with the sleeved heating tube 4 so that the wax liquid flows to the wax inlet 301 through the openings 501 and the filter cylinder 5.
[0040] Meanwhile, in order to achieve the filtration effect of filter cartridge 5, a filter screen 502 covering all openings 501 is laid on its inner wall in advance. When the wax liquid passes through the opening 501, it will be filtered by the filter screen 502. After long-term use, the filter screen 502 needs to be disassembled and pulled out to clean and replace the internal filter screen 502.
[0041] Furthermore, even though the filter cylinder 502 is surrounded by heating tubes 4 to ensure the fluidity of the wax around it, the overall circulation needs to fully guarantee the fluidity of the wax. Therefore, several heating rods 6 are installed horizontally near the filter cylinder 5. Figure 1 Similarly, the heating tube 4 in the middle has both ends passing through the wax supply box 2 for easy connection to an external power source, while the power supply for the coiled heating tube 4 can be achieved by the built-in power source located at its bottom (e.g., Figure 4 (As shown).
[0042] Working principle: The working box 1 stores wax liquid. The wax pump 3 draws the wax liquid into the working box 1. After the working box 1 is full, the wax liquid flows from the overflow port 102 to the wax supply box 2, and is then drawn back into the working box 1 by the wax pump 3 in the wax supply box 2. This cycle repeats, so that the wax liquid in the overflow port 102 is always in an overflow state, and the surface height of the wax liquid in the overflow port 102 is always at the same height. This eliminates the process of laser height detection and the process of adjusting the wax height of the robot arm, reducing the failure rate of the robot arm. At the same time, it is only necessary to add wax liquid to the wax supply box 2 before each operation.
[0043] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
