Description

Technical Field

[0001] This utility model relates to the field of mold cleaning technology, specifically to a mold cleaning device. Background Technology

[0002] Casting is a common metal processing technology that involves heating and melting metal raw materials, pouring them into a mold of a specific shape, and then allowing them to cool and solidify to form the corresponding workpiece. Casting technology is widely used in actual industrial production. For example, in the automobile manufacturing industry, parts such as engine cylinder heads and gearbox housings are made by casting.

[0003] Before using a casting mold, the dust inside its cavity needs to be cleaned to ensure processing quality. In the existing technology, if the cavity of the mold is relatively open and the opening is wide, the dust inside can be sucked out by vacuuming. If the cavity is relatively small and closed, and has holes, the air blowing method is used. First, high-pressure airflow is blown into the hole, and then the airflow carries the dust out of the hole.

[0004] However, while this method removes dust from the holes, it also causes the blown-out dust to fly everywhere. The scattered dust not only permeates the workshop air, but long-term exposure can also lead to occupational health risks such as pneumoconiosis for operators. Furthermore, the dust can easily fall onto the surface of adjacent mold cavities to be cleaned, causing secondary pollution and affecting the cleaning effect. Utility Model Content

[0005] The purpose of this invention is to provide a mold cleaning device. By setting up an air blowing component, the airflow carrying dust out comes into contact with the adhesive layer blocking the opening of the cavity. The dust then adheres to the adhesive layer, thereby preventing the dust from being blown out and scattered again, improving the cleaning effect, and also preventing dust from being generated.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mold cleaning device, including a collection box, the top of which is provided with two hollow air guide rods, and the front ends of the two hollow air guide rods are respectively provided with an air blowing component and an air suction component; The air blowing assembly includes a nozzle, and a detachable baffle is fitted on the outer end of the nozzle. Airflow is ejected from the bottom end of the nozzle. Multiple support rods are fixedly provided on the bottom end of the baffle. The support rods are distributed on the outside of the nozzle. The bottom end of the nozzle is lower than the bottom end of the support rods. An adhesive layer with an adhesive properties is provided on the bottom end of the baffle. The hollow air guide rod is fixedly provided with a bent tube at its front end. One end of the bent tube is fitted with an adjusting tube through a sealed bearing. The top of the nozzle is connected to the outer end of one of the adjusting tubes through a flange.

[0007] Furthermore, the air intake assembly includes a connecting pipe, the top end of which is connected to the outer flange of another adjusting pipe, and an air intake hood is fixedly provided at the bottom end of the connecting pipe, with multiple bristles at the bottom end of the air intake hood.

[0008] Furthermore, the hollow air guide rod is fitted with a spring and a sliding sleeve at its outer end. Both ends of the spring are fixed with annular protrusions. The annular protrusion at the front end is fixed at the rear end of the sleeve, and the annular protrusion at the rear end is fixed at the outer end of the sleeve.

[0009] Furthermore, a drive rod is hinged to the top of the sleeve, the front end of the drive rod is hinged to the outer end of the adjusting tube, and a rubber sleeve for easy gripping is fitted on the outer end of the hollow air guide rod, the rubber sleeve being located behind the spring.

[0010] Furthermore, the bottom of the collection box is equipped with multiple casters, and a partition is fixedly installed on the inner wall of the collection box. The partition divides the inside of the collection box into two non-communicating compartments, which are a high-pressure chamber and a negative-pressure chamber, respectively.

[0011] Furthermore, the front of the collection box is provided with two detachable sealing plates. Removing the two sealing plates allows for the cleaning of the interior of the two compartments. The rear of the collection box is fixedly provided with two air pumps, which are connected to the two compartments respectively.

[0012] Furthermore, each of the two compartments is equipped with a removable filter screen at its top. The top of the collection box is fixedly equipped with two hoses with valves. The top ends of the two hoses are detachably connected to the rear ends of the two hollow air guide rods, and the bottom ends of the two hoses are connected to the two compartments respectively. The bottom ends of the two hoses are located inside the two filter screens respectively.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows: 1. By setting up an air blowing component, the nozzle is inserted into the orifice-shaped cavity to blow in a high-speed airflow. The airflow carries the dust out and comes into contact with the adhesive layer blocking the cavity opening. The dust then adheres to the adhesive layer, thus preventing the dust from being blown out and scattered again. This not only prevents the dust from floating in the environment and affecting the health of the operators, but also prevents the dust from falling on the surface of the adjacent mold cavity to be cleaned and causing secondary pollution, effectively improving the cleaning effect. 2. By sliding the sleeve back and forth, the drive rod is driven, which in turn drives the adjusting tube to rotate, thereby changing the orientation of the blowing and suction components. This allows the direction of airflow and suction to be controlled according to the shape of the mold cavity, making the cleaning work more flexible. Attached Figure Description

[0016] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0017] This utility model provides, for example Figures 1-7 The mold cleaning device shown includes a collection box 3, the top of which is provided with two hollow air guide rods 1, and the front ends of the two hollow air guide rods 1 are respectively provided with an air blowing component 5 and an air suction component 6. The bottom of the collection box 3 is equipped with multiple casters, which allows the cleaning device to move around. A partition 304 is fixedly installed on the inner wall of the collection box 3, which divides the inside of the collection box 3 into two non-communicating compartments 302, namely a high-pressure chamber and a negative-pressure chamber.

[0018] The collection box 3 is provided with two detachable sealing plates 2 on the front side. The two sealing plates 2 can be removed to clean the inside of the two compartments 302 respectively. The collection box 3 is fixedly provided with two air pumps 301 at the rear end, and the two air pumps 301 are respectively connected to the two compartments 302.

[0019] The top of each of the two compartments 302 is equipped with a detachable filter screen 303. The top of the collection box 3 is fixedly equipped with two hoses 4 with valves. The tops of the two hoses 4 are detachably connected to the rear ends of the two hollow air guide rods 1 respectively. The bottom ends of the two hoses 4 are connected to the two compartments 302 respectively, and the bottom ends of the two hoses 4 are located inside the two filter screens 303 respectively.

[0020] During cleaning, one of the compartments 302 needs to be opened. The compartment 302 corresponding to the high-pressure chamber allows outside air to be introduced into the high-pressure chamber, increasing the air pressure. After opening the valve of the corresponding hose 4, the high-pressure air will be introduced into the corresponding hollow air guide rod 1 along the hose 4, thereby generating a high-speed airflow to blow away dust. The compartment 302 corresponding to the negative pressure chamber extracts air from the negative pressure chamber, creating suction due to the negative pressure inside. Opening the valve on the hose 4 of the negative pressure chamber allows the suction to be transmitted to the corresponding hollow air guide rod 1. The filter screen 303 in the high-pressure chamber filters the outside air before blowing it out, ensuring that the blown airflow is pure. The filter screen 303 in the negative pressure chamber filters the outside air, allowing the dust sucked into the mold to be collected in the filter screen 303.

[0021] To clean the narrow, perforated mold cavity, such as Figure 6 As shown, the air blowing assembly 5 includes a nozzle 501, and a detachable baffle 502 is fitted on the outer end of the nozzle 501. Airflow is ejected from the bottom end of the nozzle 501. A plurality of support rods 504 are fixedly provided at the bottom end of the baffle 502. The support rods 504 are distributed on the outside of the nozzle 501. The bottom end of the nozzle 501 is lower than the bottom end of the support rods 504. The bottom end of the baffle 502 is provided with an adhesive layer 503. The main component of the adhesive layer 503 is an acrylic pressure-sensitive adhesive, which is consistent with the adhesive composition on transparent tape in the prior art, and will not be described in detail here. The hollow air guide rod 1 is fixedly provided with a bend 101 at its front end. One end of the bend 101 is fitted with an adjusting tube 102 through a sealed bearing. The top end of the nozzle 501 is connected to the outer end of one of the adjusting tubes 102 through a flange.

[0022] Air from the high-pressure chamber is blown into the corresponding hollow air guide rod 1, and then along the hollow air guide rod 1, the bend 101, and the regulating pipe 102 into the nozzle 501. Finally, it is ejected outward through the bottom end of the nozzle 501. The nozzle 501 is suitable for cleaning narrow, perforated mold cavities. During cleaning, the bottom end of the nozzle 501 slightly protrudes into the cavity, while the bottom end of the support rod 504 supports the outside of the cavity opening. The airflow blown out by the nozzle 501 enters the cavity and then carries dust outward. However, the opening of the cavity is blocked by dust. The baffle 502 blocks the airflow, and after the airflow carries the dust out, it first comes into contact with the adhesive layer 503 at the bottom of the baffle 502, and then spreads outwards. The dust in the airflow will adhere to the adhesive layer 503 after contact with it. This not only prevents the dust from floating in the environment and affecting the health of the operators, but also prevents the dust from falling on the surface of the adjacent mold cavity to be cleaned and causing secondary pollution, effectively improving the cleaning effect and avoiding dust generation. The adhesive layer 503 will lose its stickiness after long-term use and can be replaced.

[0023] To clean the open mold cavity, such as Figure 7 As shown, the air intake assembly 6 includes a connecting pipe 601. The top end of the connecting pipe 601 is connected to the outer flange of another adjusting pipe 102. An air intake hood 602 is fixedly provided at the bottom end of the connecting pipe 601. Multiple bristles 603 are provided at the bottom end of the air intake hood 602.

[0024] The suction generated in the negative pressure chamber can be transmitted to the suction hood 602 along the hollow air guide rod 1, the bend 101, the regulating pipe 102, and the connecting pipe 601. Therefore, during cleaning, the suction hood 602 can be inserted into the relatively open mold cavity. Under the action of suction, the dust in the cavity will be sucked into the suction component 6 along with the air and eventually enter the collection box 3. The bristles 603 can rub the inner wall of the cavity during the cleaning process to clean the dust with strong adhesion.

[0025] During the mold cleaning process, it is necessary to control the direction of airflow, such as... Figures 4-7 As shown, the hollow air guide rod 1 is fitted with a spring 701 and a sliding sleeve 7 at its outer end. Both ends of the spring 701 are fixed with annular protrusions 702. The annular protrusion 702 at the front end is fixed at the rear end of the sleeve 7, and the annular protrusion 702 at the rear end is fixed at the outer end of the sleeve 7.

[0026] The top end of the sleeve 7 is hinged to a drive rod 703, the front end of the drive rod 703 is hinged to the outer end of the adjusting tube 102, and the outer end of the hollow air guide rod 1 is fitted with a rubber sleeve 103 for easy gripping, which is located behind the spring 701.

[0027] During the use of this cleaning device, the operator holds the rubber sleeve 103 and the sleeve 7 with both hands respectively. By driving the sleeve 7 to slide back and forth on the outer end of the hollow air guide rod 1, the spring 701 can be stretched or contracted. During the back and forth movement of the sleeve 7, the driving rod 703 will drive the adjusting tube 102, causing the adjusting tube 102 to rotate relative to the curved tube 101, thereby driving the blowing assembly 5 and the suction assembly 6 to rotate as a whole. This adjusts the orientation of the blowing assembly 5 and the suction assembly 6, controlling the direction of airflow and suction, making the cleaning work more flexible. The elasticity of the spring 701 can keep the sleeve 7 stable when there is no force.
