Description

Technical Field

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

[0002] Pipe piles are manufactured by adding a steel reinforcement cage and concrete material into a pipe pile mold, followed by centrifugation and curing processes. Like other concrete component molds, pipe pile molds also require a release agent to be applied to their inner walls.

[0003] Pipe pile molds are typically divided into two parts, each sprayed with a release agent separately. Existing spraying methods involve placing the pipe pile mold stationary with its inner wall facing down, and then spraying the mold from bottom to top through a spray pipe. The spray pipe is usually fixed to the bottom of the mold. However, this method often results in uneven spraying of the release agent on the inner wall of the mold, leaving some dead corners and leading to poor release performance. Therefore, this invention provides a release agent spraying device. Utility Model Content

Detailed Implementation

[0025] Example

[0026] Please see Figures 1-4 This utility model provides a technical solution: a mold release agent spraying device, including at least one base 2, multiple placement racks 3, sliding components 4, spraying components 5 and driving structure 6.

[0027] Along the length of the base 2, a spraying area is formed by a downward indentation from the upper center. Multiple placement racks 3 are fixedly connected to the upper side of the base 2 and are perpendicular to it. The upper side of the placement racks 3 is used to place the pipe pile mold. A sliding assembly 4 is located in the middle of the placement area of ​​the base 2, with both ends fixed to the inner sidewalls of the ends of the base 2 in the width direction. A spraying assembly 5 passes through the middle of the sliding assembly 4. A drive structure 6 is fixedly connected to the lower side of the spraying assembly 5. The drive structure 6 drives the spraying assembly 5 to slide within the sliding assembly 4 along the length of the base 2. As the spraying assembly 5 slides, a release agent is sprayed onto the pipe pile mold placed on the upper side.

[0028] The drive structure 6 includes a drive assembly 61, a chain 62, and a driven assembly 63. The two ends of the chain 62 are hinged to the drive assembly 61 and the driven assembly 63, respectively. The drive assembly 61 drives the chain 62 to rotate, and the driven assembly 63 rotates accordingly. The drive assembly 61 can be a motor and is located outside the base 2. The driven assembly 63 is located inside the base 2. A pair of clamping plates 11 are fixedly connected to the chain 62 near the spray assembly 5, clamping the chain 62 in the middle so that the clamping plates 11 move with the chain 62. The chain 62 is preferably a wide chain to ensure a firm and stable connection between the clamping plates 11 and the chain 62. The upper clamping plate 11 is fixedly connected to the spray assembly 5 to drive the spray assembly 5 to move.

[0029] The spray assembly 5 includes an infusion pipe 51, multiple spray pipes 52, and multiple nozzles 53. Multiple spray pipes 52 are fixedly connected to the upper side of the infusion pipe 51, and the nozzles 53 are fixedly connected to the upper ends of the spray pipes 52. A clamping plate 11 is fixedly connected to the lower side of the infusion pipe 51. A delivery hose 54 is also fixedly connected to the infusion pipe 51 near the drive assembly 61 for delivering release agent to the infusion pipe 51. The length of the delivery hose 54 is greater than the travel distance of the infusion pipe 51.

[0030] The sliding assembly 4 includes a pair of limiting rods 41, multiple sliding rods 42, and multiple pulleys 43. The pair of limiting rods 41 pass through multiple placement frames 3, with both ends fixedly connected to the side walls of the base 2. A sliding groove is formed in the middle of the pair of limiting rods 41 to match the nozzle 52, allowing the nozzle 52 to slide within the sliding groove. Multiple sliding rods 42 are fixedly connected to the side of any limiting rod 41 or the lower side of the placement frame 3, and the lower end of each sliding rod 42 is rotatably connected to a pulley 43. The pulley 43 is located directly below the pair of limiting rods 41, and a rotating groove is formed in the middle of the pulley 43 for matching the upper side of the infusion tube 51.

[0031] A support rod 21 is fixedly connected to the bottom of the base 2. A rotating wheel is rotatably connected to the upper end of the support rod 21. The rotating wheel is used to match the lower side of the infusion tube 51. The support rod 21 is located between adjacent nozzles 52.

[0032] Working principle: After the operator places the pipe pile mold on the placement frame 3 using a crane, the position is adjusted to be above the nozzle 53. The hose 54 begins to deliver the release agent into the infusion tube 51. The release agent is then sprayed upwards from the nozzle 53 through multiple spray pipes 52, thus spraying it onto the lower side of the pipe pile mold. At the same time, the drive assembly 61 is activated, which drives the chain 62 to rotate. The chain 62 drives the driven assembly 63 to rotate. After the drive assembly 61 drives the chain 62 to rotate a certain distance, it then drives the chain 62 to rotate in the opposite direction, so that the clamping plate 11 on the chain 62 is always in a horizontal back-and-forth movement. The clamping plate 11 drives the infusion tube 51 to move back and forth, thereby driving the spray pipes 52 and the nozzle 52 to move back and forth, thus spraying the pipe pile mold back and forth, improving the demolding effect.

[0033] The nozzle 52 moves back and forth within a sliding groove between a pair of limiting rods 41, which keep the nozzle 52 in a vertical position. Simultaneously, the upper side of the infusion tube 51 moves back and forth on the pulley 43, and the lower side moves back and forth on the rotating wheel on the support rod 21, reducing friction between the nozzle 52 and the infusion tube 51 during movement. The rotating wheel and support rod 21 also ensure smoother movement of the infusion tube 51.
