Description

Technical Field

[0001] This utility model relates to the technical field of magnesium alloy hot runners, and in particular to a magnesium alloy cleaning system. Background Technology

[0002] With the development of market and social demand, the demand for magnesium alloys in the electronics and digital industry, particularly in the mobile communications sector, is increasing. The concept of a magnesium alloy hot runner system involves replacing the large sprue position in an existing die-casting mold with a hot runner. However, during the production of magnesium alloy products, magnesium alloy residue is generated in the hot runner. Furthermore, the product cycle for magnesium alloys is approximately six months. If this residue is not cleaned from the hot runner when changing products, it will affect the production of the next batch. Currently, cleaning magnesium alloy hot runners requires disassembling the system from the mold and placing it in separately designed cleaning equipment. This process is not only cumbersome but also requires technicians to readjust the equipment after cleaning and reassembly, delaying production time and reducing efficiency. Utility Model Content

[0003] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a magnesium alloy cleaning system to solve the problem of cleaning magnesium alloy residues in the prior art.

[0004] To achieve the above and other related objectives, this utility model provides the following technical solution:

The plug connector is detachably installed below the hot nozzle assembly.

[0006] Furthermore, the cleaning connector includes a body, with a boss protruding outward on the side of the body away from the diverter plate; the upper surface of the boss is provided with an oxalic acid inlet facing the diverter plate.

[0007] Furthermore, the main body protrudes outward on the side facing the diverter plate to form a limiting protrusion; the limiting protrusion has a connecting hole on the side facing the diverter plate, and the connecting hole is connected to the oxalic acid inlet.

[0008] Furthermore, the diverter plate includes a main channel; the main channel, the connecting hole, and the oxalic acid inlet are coaxially arranged, and the connecting hole is connected to the main channel.

[0009] Furthermore, the main body includes a set of first internal threaded holes; the first internal threaded holes are disposed on both sides of the boss and are perpendicular to the splitter plate.

[0022] The following specific embodiments illustrate the implementation of this invention. Those skilled in the art can easily understand other advantages and effects of this invention from the content disclosed in this specification.

[0023] Please see Figure 1-5 It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying diagrams are merely for illustrative purposes to aid those skilled in the art and to facilitate understanding. They are not intended to limit the scope of implementation and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the functionality and purpose achieved, should still fall within the scope of the disclosed technical content. Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of implementation. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of implementation.

[0024] Please see Figure 1-5 This application provides a magnesium alloy cleaning system 1000, including a hot runner 1 and a cleaning device 2. The hot runner 1 includes a manifold 11 and a hot nozzle assembly 12 vertically fixed below the manifold 11. Specifically, the cleaning device 2 includes a cleaning connector 21 and a plug connector 22; the cleaning connector 21 is parallel to the manifold 11 and detachably installed above the manifold 11, and is used to connect to an oxalic acid pipe; the plug connector 22 is detachably installed below the hot nozzle assembly 12.

[0025] Furthermore, the cleaning connector 21 includes a body 211, with a boss 212 protruding outward on the side of the body 211 away from the diverter plate 11. An oxalic acid inlet 213 is provided on the upper surface of the boss 212. Through the connection between the oxalic acid inlet 213 and the oxalic acid pipe, oxalic acid can enter the magnesium alloy cleaning system 1000 from the oxalic acid inlet 213.

[0026] Furthermore, the main body 211 protrudes outward on the side facing the diverter plate 11 to form a limiting protrusion 214. The limiting protrusion 214 has a connecting hole 215 on the side facing the diverter plate 11, which is connected to the oxalic acid inlet 213. This forms a complete oxalic acid inflow channel, allowing oxalic acid from outside the system to flow into the system through the oxalic acid inlet 213.

[0027] Please continue reading. Figures 1 to 4The flow divider 11 has a main flow channel 111 and a secondary flow channel 112. The main flow channel 111, the connecting hole 215, and the oxalic acid inlet 213 are arranged on the same axis, and the connecting hole 215 is connected to the main flow channel 111. The secondary flow channel 112 is connected to the main flow channel 111. After oxalic acid enters the system through the oxalic acid inlet 213, it flows through the main flow channel 111 and the secondary flow channel 112 and finally enters the hot nozzle assembly 12.

[0028] It should be noted that the main body 211 also includes a set of first internal thread 216 holes, which are disposed opposite to each other on both sides of the boss 212 and perpendicular to the diverter plate 11.

[0029] Therefore, through the design of the cleaning connector 21, when the magnesium alloy hot runner 1 needs cleaning or the production process needs to be changed, and the magnesium alloy residue in the hot runner 1 needs to be treated, simply replace the main nozzle on the original hot runner 1 with the cleaning connector 21, and then connect the oxalic acid pipeline to achieve cleaning. This eliminates the need for the magnesium alloy hot runner 1 to enter other cleaning equipment after it is removed from the mold; it can be cleaned directly on the production line. This not only significantly saves cleaning time, but this simple cleaning method also facilitates operation by technicians, avoiding errors caused by the need to disassemble and reassemble the hot runner 1.

[0030] Please continue reading Figure 1 and Figure 5 The plug connector 22 is installed below the hot nozzle assembly 12.

[0031] The hot nozzle assembly 12 includes a hot nozzle body 121, a pouring channel 122 and a pouring port 123. The pouring channel 122 is located inside the hot nozzle body 121 and is connected to the secondary channel 112. The pouring port 123 is located at the end of the pouring channel 122 away from the secondary channel 112.

[0032] Specifically, the end of the plug connector 22 facing the hot nozzle assembly 12 has a first countersunk hole 211, the diameter of which is larger than the width of the hot nozzle body 121 in the horizontal direction.

[0033] Furthermore, a set of second internal threaded holes 222 are provided on the hole wall 2211 of the first countersunk hole 211. The second internal threaded holes 222 are set perpendicular to the hot nozzle assembly 12 and are used to cooperate with screws to realize the detachable installation of the plug connector 22 below the hot nozzle assembly 12.

[0034] In addition, the end of the plug connector 22 away from the hot nozzle assembly 12 is provided with a drain port 223. A through hole 224 is provided between the drain port 223 and the first countersunk hole 211. The two ends of the through hole 224 are respectively connected to the first countersunk hole 211 and the drain port 223, and the drain port 223, the first countersunk hole 211 and the through hole 224 are arranged on the same axis.

[0035] It should be noted that, in the embodiments of this utility model, a sewage pipe (not shown in the figure) is also included. The sewage pipe is connected to the drain outlet 223 on the plug connector 22 and is used to discharge the used oxalic acid solution into the wastewater pool.

[0036] Therefore, the design of the plug connector 22 allows for quick control of the opening and closing of the sprue 123. Before cleaning, the magnesium alloy residue in the hot runner 1 can be softened by soaking, making the subsequent cleaning work more efficient and of higher quality.

[0037] The implementation principle of the magnesium alloy cleaning system 1000 in this utility model is as follows: When the magnesium alloy hot runner 1 reaches its cleaning cycle, or when the product or process needs to be updated, it is necessary to clean the magnesium alloy residue in the magnesium alloy hot runner 1. The operator needs to stop the magnesium alloy hot runner 1 and remove the mold, replace the main nozzle in the hot runner 1 with the cleaning connector 21 in the cleaning device 2; connect the oxalic acid pipe to the oxalic acid inlet 213 on the cleaning connector 21 by plugging the nozzle interface, and plug the drain outlet 223; at this time, open the oxalic acid solution supply switch to allow the oxalic acid in the oxalic acid pipe to enter the hot runner 1. The oxalic acid solution flows from the main channel 111, through multiple secondary channels 112, and finally into the corresponding pouring channel 122. After a period of soaking and softening, open the drain outlet 223 on the plug interface. After each secondary channel 112 is cleaned, the next one is opened, and the cleaning of each secondary channel 112 and pouring channel 122 is completed in sequence.

[0038] The above embodiments are merely illustrative of the principles and effects of this invention and are not intended to limit it. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed herein should still be covered by the claims of this invention.
