Description

Technical Field

[0001] The present invention relates to the technical field of mold processing, and particularly to a deburring device for a pump body after demolding. Background Art

[0002] The injection molding of a pump body is a manufacturing process in which molten plastic is injected into a precision mold cavity and a complex-structured component is formed after cooling and solidification. In this process, first, a suitable engineering plastic (such as reinforced nylon, PPS, or PPO) needs to be selected according to the performance requirements of the pump body. The granular raw material is dried to remove moisture and then put into the hopper of the injection molding machine. Under the action of screw heating and shearing, it is plasticized into a uniform melt. The temperature control usually maintains in the range of 240 - 320°C to avoid material degradation. The melt is filled into the cavity under high pressure (80 - 150 MPa) through the mold gating system. The mold temperature controller precisely regulates the mold temperature at 60 - 120°C to balance the molding efficiency and dimensional stability. The holding pressure stage continuously compensates for shrinkage to prevent sink marks. The cooling time is calculated according to the wall thickness based on the empirical value of 1.5 - 3 mm / s. After demolding, the pump body needs to be immediately annealed to eliminate internal stress, and a shrinkage allowance of 0.2% - 0.5% needs to be reserved on the key mating surfaces.

[0003] If the burrs on the outer surface of the pump body are not thoroughly removed after demolding, it will directly affect the functionality and safety of the product, and even cause a chain of quality problems. The remaining burrs will damage the assembly accuracy. Especially at the sealing surface or the threaded connection, the burrs may cause scratches on the sealing ring or the flange surface not to fit tightly, resulting in medium leakage. In the light case, it reduces the working efficiency of the pump body, and in the heavy case, it may cause abnormal system pressure or fluid pollution. The burrs will also accelerate the wear of moving parts. For example, at the bearing mating surface or the shaft hole position, the sharp protrusions may flake off during operation and mix into the lubrication system, causing oil circuit blockage or part damage, and shortening the service life of the equipment.

By providing the first spring 52, elastic potential energy can be generated, so that the sliding plate 51 is always subjected to a squeezing force away from the connecting cylinder 415. By providing the limit rod 54, it can be adapted to the groove on the inner wall of the limit box 43, thereby preventing the sliding plate 51 from rotating when moving. One end of the moving rod 53 away from the sliding plate 51 is fixedly connected with a fixing strip 55. One side of the fixing strip 55 away from the moving rod 53 is fixedly connected with a scraper 56. The number of scrapers 56 is several, and several scrapers 56 are evenly distributed.

By setting the track tube 597, the sliding column 598 can be limited, so that the sliding column 598 can move vertically up and down in its inner cavity. By setting the second spring 599, the sliding column 598 can be extruded. By setting the roller 5911 and the polishing ring 5912, when contacting the outer surface of the pump body, it is subjected to an extrusion force, so that the moving rod 53 and the sliding plate 51 move in the inner cavity of the limiting box 43, thereby adjusting the distance between the scraper 56 and the outer surface of the pump body, preventing damage to the pump body due to too close a distance. By setting the clamping block 5913 and the clamping frame 594, when the lifting mechanism 4 drives the deburring mechanism 5 to move vertically up and down, the clamping block 5913 can be clamped into the inner cavity of the clamping frame 594, so that the polishing ring 5912 can contact the outer surface of the pump body, achieving the effect of polishing the residual burrs on the outer surface of the pump body.

[0037] Working principle: When in use, the operator places the pump body that needs to be polished and have burrs removed in the inner cavity of the placement box 34, and makes the soft pad 35 tightly contact the outer surface of the pump body. Then, the stepping motor 32 is connected to the power supply and the switch is turned on, and the rotating rod 33 is controlled to rotate forward. When the rotating rod 33 rotates, it will drive the placement box 34 and the pump body on the upper surface to rotate. During the rotation of the pump body, the roller 5911 and the polishing ring 5912 will contact the outer surface of the pump body. During the contact process, the moving rod 53 and the sliding plate 51 move in the inner cavity of the limit box 43, thereby adjusting the distance between the scraper 56 and the outer surface of the pump body to prevent damage to the pump body due to too close a distance. At the same time, the scraper 56 contacts the burrs on the outer surface of the pump body, thereby removing the burrs. Then, the polishing column 58 contacts the outer surface of the pump body with burrs removed to complete the polishing effect of the burrs. When it is necessary to adjust the height of the scraper 56 and the polishing column 58 in the vertical direction of contact with the pump body, the stepping motor 32 is controlled to rotate in reverse, so that the belt 411 drives the one-way bearing 48 and the reciprocating lead screw 46 to rotate, so that the threaded ring 413 moves vertically up and down on its outer surface, and then the forward rotation of the rotating rod 33 is resumed. When it is necessary to fully polish the remaining burrs on the outer surface of the pump body, the operator makes the stepping motor 32 rotate in reverse, so that the threaded ring 413 continuously moves vertically up and down back and forth on the outer surface of the reciprocating lead screw 46, so that the polishing ring 5912 polishes the outer surface of the pump body.
