Description

Technical Field

[0001] The utility model belongs to the technical field of casting parts, and particularly relates to a vacuum impregnation treatment device for die-castings. Background Art

[0002] In the production process of die-castings, in order to improve the performance and quality of die-castings, vacuum impregnation treatment is often required. Vacuum impregnation treatment is a technology that places die-castings in a vacuum environment and enables an impregnating agent to penetrate into the tiny pores inside the die-castings through specific process conditions. However, traditional vacuum impregnation treatment devices often have problems such as uneven distribution of the impregnating agent and poor penetration effect, resulting in the quality of die-castings being difficult to guarantee.

[0003] Specifically, traditional devices usually rely only on gravity or simple mechanical stirring to promote the uniform distribution of the impregnating agent in die-castings, but this method is often inefficient and difficult to achieve an ideal penetration effect. Especially when dealing with die-castings with complex structures, it is difficult for the impregnating agent to fully penetrate into all tiny pores, resulting in a decline in product performance.

[0004] Therefore, it is very necessary to invent a vacuum impregnation treatment device for die-castings. Summary of the Utility Model

[0005] In order to solve the above technical problems, the utility model provides a vacuum impregnation treatment device for die-castings, including an impregnation kettle. A wave-making outer shell is fixedly installed below the impregnation kettle, and a wave-making generator is installed inside the impregnation kettle and the wave-making outer shell. The output end of a driving component fixedly installed outside the wave-making outer shell penetrates into the wave-making outer shell and is fixed to the driving gear of the wave-making generator. The wave-making generator includes a transmission gear, a reciprocating gear, a reciprocating slide rod, a ring gear, a transmission sealing rod, and a wave-making head. The driving gear is respectively fixed to two mirror-symmetrically distributed transmission gears. The transmission gear and the reciprocating gear are fixedly installed on a rotating shaft seat rotatably installed inside the wave-making outer shell. The ring gear provided on the reciprocating slide rod meshes with the reciprocating gear. Two ends of the reciprocating slide rod are respectively fixedly connected to one ends of two transmission sealing rods. The other ends of the transmission sealing rods penetrate into the impregnation kettle through sliding seals and are fixed to the wave-making head inside the impregnation kettle.

[0006] Preferably, two impregnating agent nozzles and two pressure nozzles are fixedly installed on the impregnation kettle, corresponding to the impregnating agent inlet nozzle, the impregnating agent outlet nozzle, i.e., the pressure increasing port and the negative pressure port respectively.

[0007] Preferably, a kettle cover is installed on the impregnation kettle, and a wire basket placing table is fixedly installed inside. A wire basket with castings is placed on the wire basket placing table.

[0008] Preferably, two wave-making heads are symmetrically arranged in a mirror image below the wire basket storage table, and both of the two wave-making heads have symmetrical inclined surfaces.

[0009] Preferably, the ring teeth are arranged in the middle part of the reciprocating slide rod, and the two reciprocating gears alternately mesh with the ring teeth, and the ring teeth always mesh with only one of the reciprocating gears.

[0010] Preferably, the reciprocating gears are distributed on both sides of the middle of the reciprocating slide rod, and the reciprocating gears are of a gear structure with semi-circular teeth.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] The utility model improves the penetration efficiency and uniformity and optimizes the structural design, significantly improving the traditional treatment method. By introducing a wave-making generator, the wave-making heads driven by it create fluctuations in the impregnation kettle, effectively agitating the impregnating agent and accelerating its penetration into the tiny pores of the die-castings, thus greatly improving the penetration efficiency. At the same time, this fluctuation effect ensures the uniform distribution of the impregnating agent in the die-castings, significantly improving the treatment effect. In addition, the mirror-symmetric drive gears and reciprocating gear structure of the wave-making generator, in cooperation with the reciprocating slide rod and the drive sealing rod, jointly construct an efficient and stable wave generation system. The inclined surface design of the wave-making head further enhances the uniformity of the fluctuations, fully considering the structural characteristics of the die-castings, making the impregnation process more delicate and efficient.

[0020] As shown in the attached Figure 1 to the attached Figure 3 figure:

[0021] A vacuum impregnation treatment device for die-castings provided by the present utility model includes an impregnation kettle 1. A wave-making outer shell 2 is fixedly installed below the impregnation kettle 1. A wave-making generator 3 is installed in the impregnation kettle 1 and the wave-making outer shell 2. The output end of a driving component 4 fixedly installed outside the wave-making outer shell 2 penetrates into the wave-making outer shell 2 and is fixed to the driving gear 31 of the wave-making generator 3. The wave-making generator 3 includes a transmission gear 32, a reciprocating gear 33, a reciprocating slide bar 34, a ring gear 35, a transmission sealing rod 36, and a wave-making head 37. The driving gear 31 is respectively fixed to two mirror-symmetrically distributed transmission gears 32. The transmission gear 32 and the reciprocating gear 33 are fixedly installed on a rotating shaft seat rotatably installed inside the wave-making outer shell 2. The ring gear 35 provided on the reciprocating slide bar 34 meshes with the reciprocating gear 33. Both ends of the reciprocating slide bar 34 are respectively fixedly connected to one end of two transmission sealing rods 36. The other end of the transmission sealing rod 36 penetrates into the impregnation kettle 1 through a sliding seal and is fixed to the wave-making head 37 inside the impregnation kettle 1.

[0022] Furthermore, two groups of pipe orifices are fixedly installed on the impregnation kettle 1: one group is the impregnating agent pipe orifice 5, including an impregnating agent inlet pipe orifice and an impregnating agent outlet pipe orifice, which are respectively used for injecting and discharging the impregnating agent into the kettle; the other group is the pressure pipe orifice 6, that is, a pressurizing port and a negative pressure port, which are used to adjust the pressure environment in the kettle. Such a design makes the impregnation process more flexible and controllable, and can adjust the concentration of the impregnating agent and the pressure in the kettle according to actual needs to achieve the best impregnation effect.

[0023] Furthermore, in order to improve the convenience and efficiency of the impregnation treatment, a kettle cover 8 is installed on the impregnation kettle 1 to facilitate the opening and closing of the kettle body. At the same time, a wire basket placement table 7 is fixedly installed in the kettle, and the wire basket placement table 7 is specifically used for placing the wire basket containing the casting. This not only facilitates the placement and removal of the casting, but also ensures the stability and safety of the casting during the impregnation process.

[0024] Furthermore, in the design of the wave generator, a mirror-symmetrical layout is adopted, that is, two wave heads 37 are arranged in a mirror-symmetrical manner below the wire basket placement table 7. These two wave heads 37 are not only symmetrically positioned, but also each has a symmetrically designed inclined surface. Such a design enables the wave heads 37 to form a more uniform and stable wave field when generating fluctuations, thereby further improving the penetration effect and uniformity of the impregnating agent.

[0025] Furthermore, in order to achieve the efficient and stable operation of the wave generator, the transmission and meshing mechanism is precisely designed. Specifically, a ring gear 35 is provided in the middle part of the reciprocating slide rod 34, and the ring gear 35 meshes with two reciprocating gears 33 alternately. It should be noted that the ring gear 35 always meshes with only one reciprocating gear 33 at any moment, and this design ensures the stability and reliability of the transmission. At the same time, the reciprocating gears 33 are cleverly distributed on both sides of the middle of the reciprocating slide rod 34, and a gear structure with semi-circular teeth is adopted, and this design enables the gears to mesh with the ring gear 35 more effectively during rotation and transmit power.

[0026] Furthermore, in order to ensure the stable sliding of the reciprocating slide rod 34 and the transmission sealing rod 36 in the wave generating housing 2, a sliding seat (not shown in the figure) or other advanced sliding components are used for installation. These sliding components not only have good wear resistance and corrosion resistance, but also can ensure the stability and accuracy of the reciprocating slide rod 34 and the transmission sealing rod 36 during high-speed movement, thereby ensuring the overall performance and reliability of the wave generator 3.

[0027] The working principle is as follows:

[0028] First, place the wire basket containing the casting on the wire basket placement table 7 inside the impregnation kettle 1, and then close the kettle lid 8 to ensure the sealing of the impregnation kettle 1. Connect the impregnating agent inlet pipe of the impregnating agent nozzle 5 to an external impregnating agent supply system, and at the same time connect the pressurizing port and the negative pressure port of the pressure nozzle 6 to a pressure control system to prepare for adjusting the pressure inside the kettle.

[0029] Then, start the external impregnating agent supply system and inject an appropriate amount of impregnating agent into the impregnation kettle 1 through the impregnating agent inlet pipe until the preset liquid level is reached. According to the process requirements, adjust the pressurizing port and the negative pressure port of the pressure nozzle 6 through the pressure control system to bring the impregnation kettle 1 to the required vacuum or pressurized state to promote better penetration of the impregnating agent into the micro-pores of the casting.

[0030] Next, start the driving component 4 outside the wave-making housing 2, and its output end drives the driving gear 31 of the wave-making generator 3 to rotate. When the driving gear 31 rotates, it drives two mirror-symmetrically distributed transmission gears 32 to rotate synchronously in opposite directions. The transmission gears 32 further drive the reciprocating gear 33 to rotate on the rotating shaft seat inside the wave-making housing 2. The teeth of the two reciprocating gears 33 alternately engage with the ring teeth 35 on the reciprocating slide rod 34, pushing the reciprocating slide rod 34 to perform a reciprocating linear motion inside the wave-making housing 2. Since the ring teeth 35 are always engaged with only one reciprocating gear 33, the stability and reliability of the transmission are ensured. The two ends of the reciprocating slide rod 34 are respectively fixedly connected to two transmission sealing rods 36, and the transmission sealing rods 36 pass through the impregnation kettle 1 through sliding seals and are fixedly connected to the wave-making head 37. Therefore, when the reciprocating slide rod 34 performs a reciprocating motion, it will drive the wave-making head 37 to generate fluctuations inside the impregnation kettle 1, forming a wave field. Since the wave-making heads 37 are arranged in a mirror-symmetric layout and have a symmetric inclined surface design, the fluctuations generated by them can be superimposed on each other to form a more uniform and stable wave field. This wave field effectively agitates the impregnating agent, enabling it to penetrate more quickly into the micro-pores of the casting, improving the impregnation efficiency and uniformity.

[0031] When the preset impregnation time is reached or it is observed that the casting has achieved the expected impregnation effect, stop the operation of the driving component 4 to end the wave-making process. Adjust the negative pressure port of the pressure nozzle 6 through the pressure control system to restore the pressure inside the impregnation kettle 1 to atmospheric pressure. Then open the impregnating agent discharge nozzle to discharge the remaining impregnating agent from the impregnation kettle 1. Open the kettle lid and remove the casting: After confirming that the pressure inside the impregnation kettle 1 has been completely released and the impregnating agent has been discharged, open the kettle lid 8 and remove the casting that has completed the impregnation process from the wire basket placement table 7 for subsequent processing or testing.

[0032] Using the technical solution described in the present utility model, or a person skilled in the art designing a similar technical solution inspired by the technical solution of the present utility model and achieving the above technical effects shall fall within the protection scope of the present utility model.
