Description

Technical Field

[0001] The utility model relates to the technical field of mold cleaning equipment, in particular to a cleaning device for injection molds. Background Art

[0002] In today's manufacturing industry, injection molding technology is widely used in the production of various products due to its high efficiency, cost-effectiveness and ability to process complex product shapes. From daily necessities to high-end industrial parts, injection molding technology plays a key role. However, in the injection molding production process, the cleaning of surface residues after mold opening has always been a troublesome problem. These residues must be cleaned before the next injection molding.

[0003] Deficiencies of existing technology:

[0004] At present, the traditional methods of cleaning residues in injection molds mainly include chemical treatment with cleaning liquid and physical scraping. Chemical treatment with cleaning liquid is to spray specific chemical solvents directly onto the surface of the mold to dissolve or soften the residual plastic, and then remove the residue by physical wiping. The physical scraping method is to use tools to directly scrape or wipe the residues on the surface of the mold. Although these traditional methods can solve the problem of cleaning residues to a certain extent, they still have certain defects. Since chemical cleaning liquids may corrode the mold material during use, thereby shortening the service life of the mold, there is also a potential risk to the health of the operator. The physical scraping method may cause scratches or other physical damage to the mold surface during the cleaning process, thereby affecting the precision of the mold and the quality of the product. Therefore, traditional cleaning methods can no longer meet the actual cleaning needs of current injection molds. Utility Model Content

In the description of the present utility model, the meaning of "several" is two or more, unless otherwise clearly and specifically defined. Example

[0036] See also Figure 1-4As shown, the utility model provides a technical solution of a cleaning device for injection molds: a cleaning device for injection molds, comprising a mounting shell 1, a cleaning component 2 is mounted on one side of the mounting shell 1, a collecting component 3 is mounted on the other side of the mounting shell 1, and an air pipe 4 is installed through the shell of the mounting shell 1; the cleaning component 2 includes a gas tank 201, a sliding plate 202, a guide tube 204 and a heating part 206, the gas tank 201 is fixed to the inner wall of one side of the mounting shell 1 through a mounting frame, and the gas tank 201 is fixed to the inner wall of one side of the mounting shell 1 through a mounting frame, and the gas tank 201 is fixed to the inner wall of the mounting shell 1 through a mounting frame. The lower end of 01 is connected to the air outlet of the air pipe 4, the sliding plate 202 is slidably connected to the inside of the gas tank 201, and a plurality of sliding sealing rings are sleeved on the outer wall of the sliding plate 202. A booster spring 203 is connected between the sliding plate 202 and the upper top surface of the gas tank 201, and the guide tube 204 is fixedly installed at the air outlet at the lower end of the gas tank 201. The upper end of the guide tube 204 is installed with a release assembly 205. The heating part 206 is installed at the lower end of the mounting shell 1 through a bracket and is located between the guide tube 204 and the collecting assembly 3. When there is plastic residue on the surface of the injection mold after the mold is opened and needs to be cleaned, the staff will carry the device and place it on the part to be cleaned on the mold surface, and the residue is located below the heating part 206. Then the heating part 206 is energized to liquefy the plastic residue below. Then the external air pump inputs gas to the lower end of the gas tank 201 through the air pipe 4. As the air pressure increases, the sliding plate 202 overcomes the elastic force of the booster spring 203 and moves upward until the sliding plate 202 moves to the upper end of the gas tank 201 to completely compress the booster spring 203. The pressure value in the gas tank 201 is observed until the preset air pressure is reached and the external air pump is turned off. Then the mounting shell 1 is pressed downward and the release component 205 is started. Under the action of the release component 205, the high-pressure gas in the gas tank 201 is ejected outward through the guide pipe 204. During the high-pressure gas ejection process, the booster spring 203 also plays a further boosting role, so that the liquefied plastic residue on the mold surface is blown away and collected by the collecting component 3. The cleaning component 2 can be used to non-destructively blow away the plastic residues on the mold surface using pressurized gas. Compared with the traditional method of wiping with cleaning liquid or physically scraping, it will not cause corrosion or scratches on the surface of the injection mold, effectively improving the service life of the injection mold and the product quality. The plastic residues are heated before blowing away to soften or even liquefy the residues, further reducing the difficulty of cleaning and improving the cleaning efficiency.

[0037] The collecting assembly 3 includes a deflector 301 and a filter plate 302. The deflector 301 is fixedly mounted on the side of the mounting shell 1 away from the gas cylinder 201. The lower end of the deflector 301 is connected to one side of the heating part 206. The filter plate 302 is slidably connected to the deflector 301 and the slide groove on the mounting shell 1. The filter plate 302 has two layers, which can improve the efficiency of capturing the residue. After the plastic residue is blown away, it first moves forward along the gap between the mold surface and the heating part 206 under the action of high-speed airflow, and is finally intercepted by the filter plate 302. After the cleaning operation is completed, the filter plate 302 can be pulled out upward along the slide groove on the deflector 301 and the mounting shell 1 to clean the filter plate 302. Through the collecting assembly 3, the blown plastic residue is collected, which protects the working environment, and the movable filter plate 302 is easy to be pulled out and cleaned later, and can be recycled, which reduces the cleaning cost and improves the convenience of use.

[0038] The release assembly 205 includes a mounting sleeve 2051, a sealing slider 2052 and a control plate 2054. The mounting sleeve 2051 is fixedly mounted on the outer wall of the upper end of the guide tube 204. One end of the sealing slider 2052 is slidably connected to the slide groove at the upper end of the guide tube 204. The other end of the sealing slider 2052 is slidably connected to the mounting sleeve 2051. One end of the sealing slider 2052 is located inside the mounting sleeve 2051 and is provided with a return spring 2053. The control plate 2054 is rotatably connected to the handle at the upper end of the mounting shell 1. The lower end of the control plate 2054 is connected to a pull rope 2055. The lower end of the pull rope 2055 is rotatably connected to one end of the sealing slider 2052 located outside the mounting sleeve 2051. When it is necessary to open the guide tube 204 to release the high-pressure gas, the staff pulls the control plate 2054 upwards. The control plate 2054 overcomes the pulling force of the return spring 2053 by pulling the pull rope 2055 upwards, and pulls the sealing slider 2052 out of the slide groove on the guide tube 204. At this time, the guide tube 204 is unobstructed, and the gas in the gas tank 201 is discharged downward through the guide tube 204.

[0039] The lower end surface of the heating portion 206 is higher than the air outlet of the guide tube 204. Such a height setting can prevent the heating portion 206 from blocking the air outlet of the guide tube 204 and forming turbulence during exhaust.

[0040] A pressure gauge 5 is installed on one side of the mounting shell 1 above the air pipe 4. The lower end of the pressure gauge 5 passes through the mounting shell 1 and is connected to the gas tank 201. The pressure gauge 5 allows the user to monitor the pressure in the gas tank 201 in real time.

[0041] A limit ring 6 is installed at the lower end of the inner wall of the gas tank 201, and the limit ring 6 can limit the sliding plate 202 to avoid excessive displacement and damage to the pressure gauge 5 or the air pipe 4 when releasing the gas.

[0042] A sealing strip 7 is provided at the lower end of the mounting shell 1. In actual use, the sealing strip 7 can increase the sealing between the mounting shell 1 and the mold surface, ensure the moving direction of the residue when it is blown away by the high-pressure gas, and also prevent the mounting shell 1 from scratching the mold surface.

[0043] Exhaust holes are provided on the mounting shell 1 and the upper end of the gas tank 201 .

[0044] The working principle of the utility model is as follows:

[0045] When using the cleaning device for injection molds of this embodiment, the staff carries the device and places it on the part to be cleaned on the mold surface, and the residue is located below the heating part 206. Then the heating part 206 is powered on to liquefy the plastic residue below. Then the external air pump inputs gas to the lower end of the gas tank 201 through the air pipe 4. As the air pressure increases, the sliding plate 202 overcomes the elastic force of the booster spring 203 and moves upward until the sliding plate 202 moves to the upper end of the gas tank 201 to completely compress the booster spring 203. The pressure gauge 5 is observed to determine the pressure value in the gas tank 201 until the preset air pressure is reached and the external air pump is turned off. Then the mounting shell 1 is pressed downward to make the sealing strip 7 fit tightly with the mold surface, and the control plate 2054 is pulled upward at the same time. The control plate 2054 overcomes the tension of the return spring 2053 by pulling the pull rope 2055 upward, and the sealing slider 2052 is pulled out of the slide groove on the guide tube 204. At this time, the guide tube 204 is unobstructed. The high-pressure gas in the gas tank 201 is ejected outward through the guide tube 204. During the high-pressure gas ejection process, the pressure-boosting spring 203 further increases the pressure. After the plastic residue is blown away, it first moves forward along the gap between the mold surface and the heating part 206 under the action of the high-speed airflow, and is finally intercepted by the filter plate 302. After the cleaning operation is completed, the filter plate 302 can be pulled out upward along the guide cover 301 and the slide groove on the mounting shell 1 to clean the filter plate 302. The utility model has a simple structure and a reasonable design. Through the cleaning component 2, the plastic residue on the mold surface can be blown away without damage by pressurized gas. Compared with the traditional effect of wiping with cleaning liquid or physical scraping, it will not cause corrosion or scratches to the surface of the injection mold, effectively improving the service life of the injection mold and the product quality. The plastic residue is heated before blowing away, so that the residue is softened or even liquefied, further reducing the cleaning difficulty and improving the cleaning efficiency. At the same time, the blown plastic residue is collected through the collecting component 3 to protect the working environment. The movable filter plate 302 is easy to pull out and clean later and can be recycled, reducing the cleaning cost and improving the convenience of use.

[0046] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
