Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wax mold welding, in particular to a wax supply pool for stable wax supply in welding. Background Art
[0002] A wax mold tree is formed by welding multiple wax molds on a wax rod to form a tree structure, that is, a wax mold tree (wax mold group tree). Wax mold trees are often used in the field of investment casting, and are used in military, aerospace, and many civilian high-precision and sophisticated equipment. The welding process of the wax mold tree directly determines the quality of the investment casting product. If the casting is not good, bubbles will form at the welding position, resulting in the scrapping of the investment casting product.
[0003] In the traditional process of making wax mold trees, manual wax dipping is used for welding, but there are many disadvantages in such operations: the amount of wax dipped manually cannot be determined and there are differences each time; the molten wax liquid is somewhat toxic and harmful to the respiratory system of the operator; the working efficiency of manual wax dipping is low, and it is difficult to meet the requirements of industrial production.
[0004] With the progress of technology, more and more enterprises realize that using machine wax dipping is the only way to solve the above problems. However, due to the height of the wax liquid level in the wax supply pool, it will gradually decrease as the wax dipping progresses. The traditional method is to detect the liquid level, transmit the liquid level signal to the controller, and the controller selects the dipping depth according to the height of the liquid level, which results in a relatively high cost of the product.
[0005] Therefore, a structure that can ensure a constant wax dipping amount without using complex detection and calculation is needed. Summary of the Utility Model
[0006] The technical problem to be solved in the embodiment of the utility model is to provide a wax supply pool for stable wax supply in welding, which can provide a wax supply pool with a constant liquid level height for welding, and solve the problem that the liquid level decreases as the wax dipping welding progresses during the wax mold welding process, resulting in inconsistent wax dipping amounts each time.
[0007] To solve the above technical problem, the utility model provides a wax supply pool for stable wax supply in welding, including a heating wax cup, a siphon liquid supply pipe, and a wax tank. The siphon liquid supply pipe and the wax tank are located in the heating wax cup. The bottom of the wax tank is hermetically connected to the siphon liquid supply pipe. The siphon liquid supply pipe includes a siphon structure, an n-shaped elbow, and a connecting pipe. One end of the n-shaped elbow is connected to the siphon structure, and the other end is connected to the connecting pipe. The height of the siphon structure is lower than the height of the wax tank, and the height of the top bending part of the n-shaped elbow is higher than the height of the wax tank. An exhaust port is provided at the top return bending part of the n-shaped elbow.
[0008] The siphon liquid supply pipe forms two communicating vessels. Among them, the siphon structure and the n-shaped elbow are connected to form one communicating vessel, and the n-shaped elbow, the connecting pipe and the wax tank form another communicating vessel. Thus, the wax liquid is siphoned by the siphon structure and conveyed to the wax tank through the n-shaped elbow and the connecting pipe.
[0009] It further includes a liquid supply pipe, and the liquid supply pipe is connected to the n-shaped elbow between the siphon structure and the exhaust port.
[0010] One or more overflow ports are provided at the edge of the wax tank.
[0011] The wax tank is located at the central position of the heated wax cup.
[0012] The wax tank is fixedly connected to the inner wall of the heated wax cup through one or more support rods.
[0013] The liquid supply pipe is fixedly connected to the inner wall of the heated wax cup or the wax tank through another support rod.
[0014] The siphon structure is a flared structure, with a bell mouth shape at the bottom and is connected to the n-shaped elbow at the top.
[0015] The bottom of the siphon structure is close to the bottom of the heated wax cup.
[0016] A heating component is provided at the bottom of the heated wax cup.
[0017] The edge of the heated wax cup extends horizontally outward to form a smooth slope, and the outlet of the exhaust port is located above the slope.
[0018] The wax supply tank provided by the present utility model can siphon the wax liquid in the heated wax cup into the n-shaped elbow through the siphon structure, and further convey it to the bottom of the wax tank through the connecting pipe to supply wax to the wax tank. Since the height of the wax tank is lower than the height of the top bending part of the n-shaped elbow, the excess wax liquid can overflow back into the heated wax cup, thereby keeping the liquid level in the wax tank constant, providing a guarantee for welding dipping wax.

[0024] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the following will describe the specific embodiments of the present utility model in detail with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.
[0025] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.
[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.
[0027] Such as Figures 1-5As shown in the figure, the present utility model provides a wax supply tank for stable wax supply during welding, which includes a heating wax cup 1, a siphon liquid supply pipe, and a wax tank 3. Among them, the siphon liquid supply pipe and the wax tank 3 are located in the heating wax cup 1. The bottom of the wax tank 3 is sealed and communicated with the siphon liquid supply pipe. And the siphon liquid supply pipe includes a siphon structure 21, an n-shaped elbow 22, and a connecting pipe 23. One end of the n-shaped elbow 22 is connected to the siphon structure 21, and the other end is connected to the connecting pipe 23. The height of the siphon structure 21 is lower than the height of the wax tank 3, and the height of the top bending part of the n-shaped elbow 22 is higher than the height of the wax tank 3. An exhaust port 25 is provided at the top return bend part of the n-shaped elbow 22. The n-shaped elbow 22 only needs to have an n-shaped bending part, and its shape can also be other shapes with an n-shaped bending part. The main structure of the connecting pipe is a horizontal section and a vertical section, and its function is to connect the n-shaped elbow and the wax tank 3. Its shape can also be an inclined straight pipe, an arc-shaped pipe, or other complex-structured pipelines on this basis. The design of the exhaust port 25 is very crucial. When the wax liquid flows along the n-shaped elbow 22 and reaches the top bending part, the air bubbles will be discharged through the exhaust port 25, so that the wax liquid flowing into the wax tank 3 later has no air bubbles. At the same time, since in the subsequent flowing process, it is supplied to the bottom of the wax tank 3 and no longer contacts the air.
[0028] The siphon liquid supply pipe forms two communicating vessels. Among them, the siphon structure 21 and the n-shaped elbow 22 are connected to form a communicating vessel, and the n-shaped elbow 22, the connecting pipe 23, and the wax tank 3 form another communicating vessel. Thus, the wax liquid is siphoned by the siphon structure 21 and transported to the wax tank 3 through the n-shaped elbow 22 and the connecting pipe 23.
[0029] The wax supply tank provided in this embodiment further includes a liquid supply pipe 24, and the liquid supply pipe 24 is connected to the n-shaped elbow 22 between the siphon structure 21 and the exhaust port 25.
[0030] One or more overflow ports 31 are provided at the edge of the wax tank 3. The overflow ports 31 can ensure a constant liquid level, discharge the excess wax liquid through the overflow ports 31 and return it to the heating wax cup 1. The design of the overflow ports 31 can also make the excess wax liquid be discharged concentratedly, rather than overflow evenly around the heating wax cup 1, thus avoiding the liquid level bulging and unstable height.
[0031] The wax tank 3 is located at the central position of the heating wax cup 1, so as to facilitate the wax liquid recovery of the wax tank 3 and make the wax liquid temperature around the wax tank 3 the same.
[0032] The wax tank 3 is fixedly connected to the inner wall of the heating wax cup 1 through one or more support rods 11. The support rods 11 are arranged horizontally, or can also be arranged vertically.
[0033] The liquid supply pipe 24 is fixedly connected to the inner wall of the heating wax cup 1 or the wax tank 3 through another support rod, ensuring that the position of the liquid supply pipe 24 relative to the wax tank 3 is fixed.
[0034] The siphon structure 21 is a flared structure with a bell mouth shape at the bottom and is connected to the n-shaped elbow at the top.
[0035] The bottom of the siphon structure 21 is close to the bottom of the heating wax cup, thereby forming a greater drop with the wax tank 3, resulting in a better siphon effect and allowing a greater range of liquid level changes in the heating wax cup 1.
[0036] A heating component 12 is provided at the bottom of the heating wax cup 1, and the heating component heats the heating wax cup 1 by means of electric heating or electromagnetic heating.
[0037] The edge of the heating wax cup 1 extends horizontally outward to form a smooth slope, and the outlet of the exhaust port 25 is located above the slope.
[0038] The wax supply tank provided by the present utility model can siphon the wax liquid in the heating wax cup into the n-shaped elbow through the siphon structure, and further convey it to the bottom of the wax tank through the connecting pipe to supply wax to the wax tank. Since the height of the wax tank is lower than the height of the top bending part of the n-shaped elbow, the excess wax liquid can overflow back into the heating wax cup, thereby keeping the liquid level in the wax tank constant and providing a guarantee for welding wax dipping.
[0039] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.
[0040] The above-described embodiments only represent several implementation manners of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
