Description

Technical Field

[0001] This utility model relates to the field of mold release agent spraying technology, specifically to a high-efficiency mold release agent spraying device. Background Technology

[0002] Mold release agent is an interface coating applied to the surfaces of two objects that are prone to adhesion. It is typically used between a mold and a mold part to form an inert coating, allowing the mold part to be easily removed from the mold. Mold release agent is applied to the mold using a spraying device.

[0003] Utility model patent CN202021161060.9 discloses a spraying device for a pipe mold release agent. This device includes a support base, a spraying box fixedly connected to the top of the support base, a working frame fixedly connected to the top of the spraying box, a first motor fixedly connected to the inner wall of the working frame, a worm gear fixedly connected to the output end of the first motor, a drive wheel meshing with the outer side of the worm gear, a first stirring rod fixedly connected to the inner ring of the drive wheel, the bottom of the first stirring rod penetrating the spraying box and extending into the inner cavity of the spraying box, a driven wheel meshing with the outer side of the drive wheel, and the inner ring of the driven wheel... A second stirring rod is fixedly connected to the ring. The bottom of the second stirring rod penetrates through the spray box and extends into the inner cavity of the spray box. A water pump is connected to one side of the spray box. A guide pipe is connected to the top of the water pump. A support column is fixedly connected to the top of the support base and to one side of the water pump. A frame is fixedly connected to the top of the support column. A second motor is fixedly connected to the bottom of the inner cavity of the frame. A threaded rod is fixedly connected to the output end of the second motor. A threaded sleeve is threadedly connected to the outer side of the threaded rod. An atomizing tube is fixedly connected to the bottom of the threaded sleeve. The end of the guide pipe away from the water pump is connected to the side of the atomizing tube. A mold body is fixedly connected to the top of the working frame. By using the drive wheel and driven wheel in combination, the user turns on the first motor and the second motor via a switch. The first motor drives the drive wheel and the driven wheel to rotate via a worm gear. The drive wheel and the driven wheel drive the first stirring rod and the second stirring rod to rotate. The water pump delivers the release agent into the atomizing tube through the guide pipe. The second motor drives the threaded sleeve and the atomizing tube to move left and right via a threaded rod, resulting in more uniform spraying. This solves the problem that in existing spraying equipment, the release agent tends to clump and solidify during use, resulting in poor spraying effect and the release agent not being able to adhere evenly to the pipe mold.

[0004] Although the mold release agent spraying equipment for pipe molds achieves uniform spraying, the device still has the following problems in actual use: When spraying the release agent, the device directly sprays it onto the mold through multiple nozzles. However, during this process, a certain spatial distance is maintained between the nozzles and the mold. While this design ensures uniformity and flexibility of spraying, some release agent splashes due to the dynamic force of the spraying process, falling onto the ground or workbench around the mold. This phenomenon not only causes environmental pollution but may also adversely affect the overall cleanliness of the production site and subsequent work processes. Therefore, we propose a high-efficiency mold release agent spraying device. Utility Model Content

Thanks to the housing, the release agent does not spread to the outside. This design facilitates uniform and comprehensive application of the release agent to the mold while preventing the release agent from spreading and contaminating the external working environment.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This embodiment provides a technical solution:

[0028] Please see Figures 1-4 As shown, the high-efficiency mold release agent spraying device includes a hollow housing 1 for storing the release agent. A liquid pump 10 is installed below the front end of the housing 1, with its inlet connected to the housing 1 and a drain hose 11 installed at its outlet. A lifting part 2 is provided on the top of the housing 1, including a bracket 20. A lead screw 21 is rotatably installed inside the opening of the bracket 20, and a movable seat 24 is threadedly connected to the lead screw 21. A device for driving the lead screw 21 is installed on the top of the bracket 20. A rotating motor 23; two crossbars 25 are fixed to the front end of the movable seat 24; a spraying part 3 is provided between the front ends of the two crossbars 25. The spraying part 3 includes a cover 30 with an open bottom. A horizontal pipe 31 is fixed to the top of the inner wall of the cover 30. Multiple branch pipes 32 are fixed to the outer wall of the horizontal pipe 31 on both the front and rear sides. Multiple nozzles 33 are fixed to the bottom of the branch pipes 32. A bent pipe 34 is installed at the top of the outer wall of the horizontal pipe 31. The end of the bent pipe 34 passes through the cover 30 and is connected to the drain hose 11.

[0029] In this embodiment, the bracket 20 has a U-shaped cross-section and is fixedly connected to the top of the housing 1 by bolts. The U-shaped bracket 20 has better structural strength and support performance, while the bolt fixing method further ensures the installation stability and reliability of the bracket 20.

[0030] In this embodiment, guide rods 22 are fixed on both sides of the opening of the bracket 20. The guide rods 22 pass through the movable seat 24 and are slidably connected to the movable seat 24. The guide rods 22 guide the lifting and lowering movement of the movable seat 24, ensuring the stability and smoothness of the lifting and lowering of the movable seat 24.

[0031] In this embodiment, a liquid inlet 12 is installed at the top rear end of the housing 1, and a plug is threaded onto the liquid inlet 12. The liquid inlet 12 facilitates the replenishment of release agent into the housing 1, while the plug facilitates the sealing of the liquid inlet 12.

[0032] In this embodiment, a tie rod 26 is provided between the two crossbars 25, and the combined shape of the crossbars 25 and the tie rod 26 is H-shaped. The tie rod 26 increases the stability and reliability of the connection between the two crossbars 25, ensuring the support effect on the cover 30.

[0033] In this embodiment, the cover 30 is fixedly connected to the crossbar 25 by bolts, and the cover 30 is made of aluminum alloy. The bolt fixing method ensures the reliability and stability of the connection between the cover 30 and the crossbar 25, while the aluminum alloy material has the advantages of corrosion resistance and light weight, ensuring the service life of the cover 30.

[0034] In this embodiment, the branch pipes 32 are linearly and equally spaced in the horizontal direction, and the branch pipes 32 are fused and fixed to the horizontal pipes 31. The arrangement of multiple branch pipes 32 facilitates the installation of multiple nozzles 33, thereby improving the uniformity of the release agent spraying.

[0035] It should be added that the drain hose 11 in this embodiment is flexible. This design is beneficial for both the delivery of the release agent by the drain hose 11 and the stretching of the drain hose 11, thereby meeting the height adjustment requirements of the cover 30.

[0036] It is worth noting that the motor 23 and the liquid pump 10 involved in this embodiment are existing conventional technologies, and will not be described in detail here.

[0037] In actual use, the user first turns on the power to the motor 23, and the motor 23 starts to work. The output shaft of the motor 23 rotates, which drives the lead screw 21 to rotate. As the lead screw 21 rotates, the movable seat 24 drives the crossbar 25 and the cover 30 to move downward. When the cover 30 covers the outside of the mold, the user turns off the power to the motor 23. Then the user turns on the power to the liquid pump 10, and the liquid pump 10 starts to work. The release agent in the box 1 enters the drain hose 11, and enters the horizontal pipe 31 and multiple branch pipes 32 through the bend pipe 34. At this time, the release agent is sprayed onto the mold through multiple nozzles 33.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
