[0037] The present disclosure will be further described below with reference to the accompanying drawings and embodiments.

[0038] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which the present application belongs.

[0039] In recent years, with the steady improvement of the overall social level and the continuous development of scientific and technological strength, the application areas of metal products have also been greatly extended. They have been widely used in different industrial fields such as heavy industry, light industry and handicrafts. In the casting process of metal-like column products, an indispensable key link is the cooling and forming of the metal column in the middle and late stages of metal casting.

[0040] As recorded in the background technology, although the hot metal cooling rings currently used have mature technology and stable application, there is currently no effective solution to the problem of oil accumulation inside and outside the cooling rings after long-term use except for manual disassembly. Manual disassembly and cleaning is time-consuming and labor-intensive. The systematic disassembly and cleaning process of a single cooling ring requires two skilled workshop workers for 15 to 20 days, and the cleaning efficiency is not high, and efficient cleaning cannot be achieved, which brings huge manpower and financial pressure to the company for post-use maintenance. In addition, the suspension of the casting equipment during the maintenance period has also brought immeasurable economic benefits to the company.

[0041] In the production process of metal columns, using molds to constrain molding is one of the main steps, and whether the mold is clean or not is closely related to the quality of metal column molding. When the oil and water added during the casting process form oil stains that block the cooling water outlet due to incomplete cleaning, the quality of the outflowing metal column will be greatly reduced or even scrapped, consuming huge manpower and material resources. However, for the current cleaning of metal column cooling molding molds, automated cleaning has not been achieved, and manual cleaning efficiency is extremely low. It takes workers nearly a month to clean once, which greatly increases the overall output cost of the metal column. Moreover, since the molds that need to be cleaned are large in size and relatively complex in structure, incomplete cleaning often occurs, which greatly reduces the pass rate of metal columns. Therefore, there is an urgent need to improve the cleaning efficiency and casting quality of metal column cooling molding molds.

[0042] Example 1:

[0043] like Figure 1 As shown, this embodiment provides a cleaning device for a metal column cooling forming mold, comprising a cleaning box 1 and a mold placement tray 2;

[0044] A plurality of telescopic rods 11 are vertically provided at the bottom of the cleaning box 1, and a hole plug 12 is provided at one end of the telescopic rod 11 away from the bottom of the cleaning box 1; a water inlet 13 is also provided at the bottom of the cleaning box 1, and a water outlet 14 is provided on one side of the cleaning box 1;

[0045] The mold placement tray 2 includes a bottom plate 21 and a baffle 23. A fixing plate 22 parallel to the bottom plate 21 is provided on the baffle 23. The fixing plate 22 is provided with a plurality of mold placement holes 24. A water outlet interlayer is formed between the bottom plate 21 and the fixing plate 22. A water outlet long hole 25 is opened on the side of the water outlet interlayer.

[0046] The inner bottom surface of the cleaning box 1, the enclosure 23 and the fixed plate 22 constitute a cleaning space; it is understandable that the mold placement tray 2 is upside down in the cleaning box 1, and the edge of the mold placement tray 2 can be stuck on the positioning baffle 15 and the protrusion where the water inlet 13 is located to achieve the construction of the cleaning space, and the contact strength between the edge of the mold placement tray 2 and the bottom surface of the cleaning box 1 can also be achieved by placing a gravity block on the bottom plate 21 or directly weighting the bottom plate 21; it is also understandable that a rubber strip is provided at the edge of the mold placement tray 2 to achieve a sealing effect when in contact with the bottom surface of the cleaning box 1.

[0047] In this embodiment, the telescopic rod 11 can be configured as a pneumatic telescopic rod.

[0048] In this embodiment, the hole plug 12 includes a first elastic section 121 close to the telescopic rod 11 and a second elastic section 122 away from the telescopic rod 11. The hardness of the second elastic section 122 is greater than that of the first elastic section 121. It can be understood that the hole plug 12 is used to fill the opening of the metal ring for cooling hot metal. The relatively hard second elastic section 122 at the top achieves effective impact during insertion, achieving a basic sealing effect and making sufficient preparations for subsequent mold cleaning.

[0049] Specifically, the first elastic section 121 can be configured as a medium-soft silicone cylinder, and the second elastic section 122 can be configured as a hard material with a certain degree of penetration. One side of the second elastic section 122 is designed as a dome plane, and the other side is embedded with the first elastic section 121.

[0050] The telescopic rod 11 drives the hole plug 12 to move, and can switch back and forth between two working modes: filling the pores of the mold 3 and separating from the mold 3.

[0051] In this embodiment, the diameter of the second elastic section 122 is smaller than the diameter of the first elastic section 121 ; the diameter of the first elastic section 121 is larger than the inner diameter of the mold to be cleaned.

[0052] In this embodiment, a plurality of positioning baffles 15 are provided around the bottom of the cleaning box 1; a protrusion for positioning the mold placement tray 2 is also provided around the bottom of the cleaning box 1, and the water inlet 13 is provided on the protrusion; four protrusions can be provided, distributed at the four corners of the bottom of the cleaning box 1;

[0053] Specifically, the positioning baffle 15 assists in accurately positioning the mold placement tray 2 when pressing the mold placement tray 2 against the lower part of the cleaning box 1; it can be understood that the side of the enclosure 23 is in contact with the positioning baffle 15, and the multiple positioning baffles 15 distributed around the lower part of the cleaning box 1 realize the positioning of the mold placement tray 2; the protrusion also has the same function as the positioning baffle 15, and also has the function of positioning the mold placement tray 2.

[0054] In this embodiment, a rubber strip is provided at one end of the enclosure 23 away from the bottom plate 31 .

[0055] In this embodiment, in the cleaning space, each hole plug is coaxially arranged with its corresponding mold placement hole.

[0056] In this embodiment, the long water outlet hole 25 is provided on one end of the enclosure 23 close to the bottom plate 21 .

[0057] The working principle of this embodiment is as follows: when the cleaning liquid / clean water enters the device from the water inlet 13, the liquid fills the cleaning space. When the liquid fills the cleaning space, the water pump fills the water and pressurizes it. The first elastic section on the telescopic rod 11 is clamped with the mold hole. At this time, the mold 3 and the plug 12 are plugged and pressed to form a sealed state: the first step: soaking. At this time, the liquid infiltrates the mold 3, and a sufficient chemical reaction occurs between the cleaning liquid and the oil to achieve a preliminary cleaning effect. After soaking for the set time, the second step: high-pressure flushing is performed. At this time, the pressurized cleaning liquid / clean water enters from the water inlet 13 at high pressure: ensure that the water inlet 13 and the mold The placement tray 2 is matched and combined to ensure that water flows smoothly into the cleaning / rinsing process and ensures that the individual casting mold and the hole plug 12 controlled by the telescopic rod 11 are accurately positioned; each mold is sequentially cleaned / rinsed for 5-10 seconds. After the cleaning is completed, the water pump releases the pressure, and the hole plug 12 is also separated from the individual casting mold. The overflowed mixture / clean water circulates through the water outlet 14 to ensure the flushing efficiency. The above operation is then repeated until the last mold is cleaned. At this time, the cleaning process of the entire set of metal column cooling forming molds is completed. It can be understood that all actions can be implemented by a controller, which can be configured as a PLC.

[0058] It can be understood that when flushing a single plug hole, after the plug 12 leaves the mold 3, the cleaning liquid or clean water gushing out of the mold 3 will first reach the water outlet interlayer, and then instantly gush out to the water outlet interlayer through the long water outlet hole, and will also quickly flush the outer edge of the mold 3, and then return to the base along the inner cavity and flow out through the water outlet 14.

[0059] Example 2:

[0060] like Figure 5 As described, this embodiment provides a cleaning system for a metal column cooling forming mold, including a first liquid supply system, a second liquid supply system and a cleaning device for a metal column cooling forming mold as described in Example 1; the water supply ends of the first liquid supply system and the second liquid supply system are both connected to the water inlet 13, and the water inlet ends of the first liquid supply system and the second liquid supply system are both connected to the water outlet 14.

[0061] In this embodiment, the first liquid supply system includes a first pump 4, a first storage tank 5, and a second pump 6 connected in sequence;

[0062] The first pump 4 is connected to the water outlet 14 , and the second pump is connected to the water inlet 13 .

[0063] In this embodiment, the second liquid supply system includes a third pump 7, an oil-water separator 8, a second storage tank 9 and a fourth pump 10 connected in sequence; the oil-water separator 8 can be implemented using existing technology;

[0064] The third pump 7 is connected to the water outlet 13 , and the fourth pump 10 is connected to the water inlet 13 .

[0065] Example 3:

[0066] This embodiment provides a method for cleaning a metal column cooling forming mold, which uses the cleaning system for the metal column cooling forming mold described in Example 2; the method comprises:

[0067] During the soaking stage, the telescopic rod 11 pushes the hole plug 12 into the end of the mold to be cleaned close to the cleaning space; the cleaning liquid fills the cleaning space, and the cleaning liquid reacts chemically with the oil stains;

[0068] During the cleaning phase, the telescopic rod 11 brings the hole plug 12 out of the mold to be cleaned, and the cleaning liquid in the cleaning space flows through the mold in sequence to the water outlet interlayer, the water outlet long hole 25, the cleaning box 1, the gap between the mold placement plate 2 and the water outlet, and the mold is cleaned during the flow of the cleaning liquid.

[0069] In this embodiment, the cleaning stage includes a cleaning liquid cleaning stage and a clean water cleaning stage.

[0070] In this embodiment, during the cleaning liquid cleaning stage, the second liquid supply system works and the oil-water separation device 8 performs oil-water separation; the oil-water separation device 8 adopts one of the existing equipments that can realize the oil-water function; after the second liquid supply system stops working, the first liquid supply system works and enters the clean water cleaning stage.

[0071] In the present disclosure, through the coordinated operation of multiple electrically controlled pneumatic rods, rapid cleaning of a single site in about 5 seconds is achieved, and dozens or hundreds of metal rings can be effectively cleaned in a relatively short period of time. The cleaned water can be recycled, further reducing the waste of water resources. The present disclosure effectively solves the post-use maintenance problem that has plagued metal casting companies for many years, greatly reduces the resource consumption of manpower and corporate equipment post-use maintenance, increases the possibility of water resources being reused, further optimizes the allocation and use of natural resources, and makes certain contributions to ecological environmental protection and industry technological development.

[0072] The above description is merely a preferred embodiment of this embodiment and is not intended to limit this embodiment. Those skilled in the art will readily appreciate that this embodiment may be modified and varied in various ways. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this embodiment shall be within the scope of protection of this embodiment.
