Description

Technical Field

[0001] This invention relates to the field of mold auxiliary technology, specifically to an auxiliary device for casting automotive parts. Background Technology

[0002] In the casting process of automotive parts, wood core making technology is a commonly used process. By using wood to make a mold of a specific shape and filling it with sand core material, the required cavity can be formed. This method has advantages such as high flexibility, low cost and easy processing. As a key component in the casting process, the sand core is placed inside the sand mold and is mainly used to form the cavity or channel inside the part. It can ensure the accuracy and consistency of the internal dimensions and shape of the cast part, thereby improving the quality and performance of the casting.

[0003] In practice, to ensure the quality and performance of castings, a dust blowing operation is usually required after the sand core is made. This step aims to remove impurities that may exist on the surface and inside of the sand core, such as sand particles, fibers, and wood chips. If these impurities are not removed, they will form bubbles during the casting process, affecting the quality of the castings.

[0004] Before die casting, a cooling release agent is usually added to the surface of the sand core to facilitate demolding. The cooling release agent can reduce the adhesion between the sand core and the mold, allowing the casting to be easily removed from the mold and improving production efficiency.

[0005] However, the existing dust blowing and adding cooling release agent operations are usually done manually by workers, which increases the complexity and time cost of the operation. At the same time, due to the operation intervals, dust or dirt will accumulate on the surface of the casting again, affecting the quality and smoothness of the casting surface. In addition, due to the complexity of the sand core structure, some hard-to-reach areas cannot be thoroughly cleaned or coated, resulting in incomplete cleaning effect.

[0006] In addition, the molten metal releases a lot of heat when it is injected into the mold. This heat is conducted into the mold and keeps it at a high temperature. This not only puts a heat load on the mold itself, but also causes harmful substances inside the mold to volatilize and accumulate. These volatile organic compounds can have a negative impact on the surrounding environment and the health of workers in a high-temperature environment. In addition, a high-temperature environment can also have an adverse effect on the surrounding equipment and machinery, such as overheating of electronic equipment, mechanical failure or damage.

[0012] Preferably, the locking assembly further includes a locking slide rod, which is symmetrically slidably connected to the bottom of the locking support plate. A locking spring is fixedly connected to the end of the locking slide rod away from the center of the locking support plate, and a limit block is fixedly connected to the end of the locking slide rod near the center of the locking support plate.

[0013] Preferably, the air control tooth meshes with the double toothed plate, the reciprocating tooth meshes with the double toothed plate, and the top end of the telescopic sleeve is inclined toward the center of the supporting base.

[0014] Preferably, the liquid control groove meshes with the rotating gear, the reversing bevel gear meshes with the functional bevel gear, the liquid control ratchet is slidably connected to the inner sidewall of the double groove plate, and the carrier plate is in contact with the top surface of the functional bevel gear.

[0018] Compared with the prior art, the beneficial effects of the present invention are: 1. By using the air outlet and suction of the telescopic sleeves on the opposite side to work together, the dust and impurities on the complex shape of the bottom mold are effectively removed, ensuring the effectiveness of the dust cleaning work of the bottom mold. At the same time, by automatically cleaning the dust and impurities of the bottom mold during the displacement of the bearing platform, the impurities or dust inside the sand core of the bottom mold are avoided, which may cause air bubbles in the casting. 2. Through the reciprocating motion of the telescopic sleeve, the atomized cooling release agent is sprayed more widely on the bottom mold, realizing the simultaneous cleaning of dust and spraying of cooling release agent. This avoids the situation where dust or dirt accumulates again on the surface of the bottom mold due to the interval between cleaning and spraying. At the same time, the airflow system and the complex shape of the bottom mold are combined to ensure that the cooling release agent can be completely coated on the bottom mold. 3. The vertical direction of the umbrella-shaped locking rod is limited by the limiting block, which in turn limits the vertical direction of the bearing top platform and the bearing bottom platform. This prevents the thermal expansion of the sand mold inside the top mold and bottom mold from causing the top mold and bottom mold to separate. This avoids the situation where the molten metal seeps into the separation gap of the sand mold due to the separation of the top mold and bottom mold, resulting in uneven metal flow. This ensures that the dimensions of the casting meet the design requirements and improves the production quality of the casting. 4. Hot air is discharged to the outside through the air intake pipe, and at the same time, the spraying component sprays cooling release agent towards the support base. The atomization effect cools the hot air, ensuring that all air discharged to the outside through the air intake pipe is cooled, thus ensuring the safe use of surrounding equipment. At the same time, by absorbing hot air, the production safety of surrounding workers is guaranteed, which has a positive effect on sand casting. Attached Figure Description

[0025] The support base 2 is equipped with a spraying component for spraying cooling release agent; The spraying assembly includes a speed-increasing liquid control block 713, which is fixedly connected to the top of the telescopic sleeve 61. The speed-increasing liquid control block 713 is internally connected to the liquid pipe 714.

[0028] Wherein: the locking spring 84 is sleeved on the surface of the locking slide bar 83, and the bottom surface of the limiting block 85 is set as an inclined surface.

[0029] The working principle of the present invention, based on the above embodiments, is explained as follows: The initialization steps are as follows: Workers inject cooling release agent into the liquid tank 719, install the bottom mold to be sand-cast on the top of the support base 2, and install the top mold to be sand-cast inside the support top platform 5.

[0030] The physical principles involved are: Bernoulli's Law: Based on the continuity equation and the principle of energy conservation, Bernoulli's Law applies to incompressible, low-viscosity, and steady-state flows. According to Bernoulli's Law, for an ideal fluid along a streamline, as its velocity increases, the pressure decreases, while the height remains constant. The specific statement is as follows; Fluid velocity: When fluid flows through a pipe or flow device, if the cross-sectional area narrows, for example, the pipe contracts, the mass flow rate remains constant according to the continuity equation. Since the mass flow rate is proportional to the velocity, the fluid velocity will also increase when the velocity increases through the narrow section. Pressure changes: According to the principle of conservation of energy, as velocity increases, the kinetic energy of a fluid also increases. According to Bernoulli's principle, when velocity increases, the kinetic energy of the fluid increases, therefore the pressure decreases. In other words, the increase in the kinetic energy of a fluid is achieved by reducing its static pressure.

[0031] The operation steps are as follows: During the movement of the supporting base platform 2, the cleaning component disturbs the airflow to clean dust and impurities on the bottom mold. In practical applications, sand cores are typically placed in the mold cavity before the mold is closed and molten metal is injected. However, after placing the sand core, a dust-blowing operation is usually required. This is because during the sand core manufacturing process, some impurities, such as sand particles, fibers, and wood chips, may mix into the sand core material. Furthermore, the binder in the sand core decomposes and releases gases at high temperatures. If there are a large number of impurities or dust inside the sand core, these gases cannot escape smoothly, thus forming bubbles in the casting.

[0032] like Figures 1 to 9 As shown, at this time, the operator electrically controls the support platform 2 to be energized via an external control panel. The energized support platform 2 slides from the top of the working platform 1 towards the equipment door 3. Simultaneously with the displacement of the support platform 2, the air control gear 67 moves synchronously on the surface of the double toothed plate 65, causing the air control gear 67 to drive the shafted fan 66 fixedly connected to it to rotate. The shafted fan 66 located near the liquid control tooth groove 71 rotates upwards, disturbing the air, while the shafted fan 66 located away from the liquid control tooth groove 71 rotates at the bottom of the housing, disturbing the air. While the axial fan 66 on one side disturbs the air, the disturbed air enters the interior of the telescopic sleeve 61 through the intake duct 62. Because the cross-sectional shape of the intake duct 62 is wider at the bottom and narrower at the top, according to Bernoulli's law mentioned above, when fluid passes through a pipe or flow device, if the cross-sectional area narrows (e.g., the pipe contracts), the mass flow rate remains constant according to the continuity equation. Since the mass flow rate is proportional to the velocity, when the velocity increases, the fluid velocity through the narrow section also increases. Furthermore, according to the principle of energy conservation, the kinetic energy of the fluid also increases with increasing velocity. According to Bernoulli's law, when the velocity increases, the kinetic energy of the fluid increases, thus the airflow is accelerated inside the intake duct 62 and moves towards the telescopic sleeve 61. The high-speed airflow is then released to the outside from the top outlet of the telescopic sleeve 61. While the telescopic sleeve 61 on the side close to the liquid control groove 71 releases high-speed airflow to the outside, the telescopic sleeve 61 on the side away from the liquid control groove 71 draws air from the outside through its top air outlet and moves into the telescopic sleeve 61. While the base platform 2 is displaced, the reciprocating gear 64 simultaneously moves on the surface of the double-tooth plate 65, causing the double-groove spiral rod 63, which is fixedly connected to the reciprocating gear 64, to rotate. Simultaneously, the double-groove spiral rod 63 rotates on its own axis, causing the sliding block 68 sliding on its surface to tend to rotate as well. Since the double-groove spiral rod 63 is rotatably connected to the telescopic sleeve 61 via the sliding block 68, and the sliding block 68 is slidably connected to the limiting guide rod 610 via the telescopic sleeve 61 and the single carrier plate 69, the sliding... The rotation tendency of block 68 is limited by the limiting guide rod 610. As the double groove helical rod 63 rotates, it drives the sliding block 68 to move. During the sliding process of the sliding block 68 on the surface of the double groove helical rod 63, the sliding block 68 tends to rotate accordingly following the change of the surface texture of the double groove helical rod 63. Because the telescopic sleeve 61 is rotatably connected to the sliding block 68, the sliding block 68 cannot rotate under the restriction of the telescopic sleeve 61. As a result, the sliding block 68 drives the top of the telescopic sleeve 61 to move up and down reciprocally. At the same time, because the double threads on the surface of the double groove spiral rod 63 are set with opposite textures and internally connected, the displacement of the telescopic sleeve 61 is a reciprocating motion with the rotation of the double groove spiral rod 63. Therefore, the top of the symmetrically arranged telescopic sleeve 61 disturbs the air flow to the outside. Thus, the telescopic sleeve 61 is in reciprocating motion and disturbs the air flow on the bottom mold surface facing the air outlet of the telescopic sleeve 61. When air outlet and air intake occur simultaneously, a high-pressure area is generated at the air outlet, while a low-pressure area is formed at the air intake. According to the principle of airflow, the high-pressure airflow will naturally flow to the low-pressure area, thus forming an airflow circulation. Due to the complex shape of the bottom mold, the dust and impurities on its surface are usually scattered and not easily removed by airflow in one direction. However, by setting air outlet and air intake on opposite sides, a relatively powerful airflow system can be formed. When the air outlet generates high-pressure airflow, it will push the surrounding air and form an airflow environment. This airflow environment will stir up the dust and impurities on the plane and suspend them in the air. At the same time, the low-pressure area formed by the air intake will attract the surrounding air and the suspended dust and impurities. Due to the airflow, the dust and impurities will be quickly drawn into the air intake and enter the interior of the telescopic sleeve 61 on the side away from the liquid control groove 71, and then discharged to the outside through the telescopic sleeve 61 and the air intake pipe 62. During this process, due to the reciprocating motion of the telescopic sleeve 61, the distance between the air outlet and the suction applied to the bottom mold surface changes, which allows the airflow to better cover the surface of the complex plane. The appropriate position and angle can ensure that the contact area between the airflow and the surface is maximized, making it easier for dust and impurities to be sucked away. By using the air outlet and air intake of the telescopic sleeve 61 set on the opposite side to effectively remove dust and impurities on the complex shape of the bottom mold, the dust cleaning work of the bottom mold is ensured. At the same time, by automatically cleaning the dust and impurities of the bottom mold during the displacement of the bearing base 2, the impurities or dust inside the sand core of the bottom mold that may cause air bubbles in the casting are avoided. The cleaning and spraying components operate in tandem: The existing dust removal and mold release machine operation is usually carried out manually by workers holding air guns and spray guns in multiple steps, separating dust removal and spraying cooling mold release agent into two independent steps. This means that there is a time interval between the operations. This discontinuity will increase the complexity of the operation and may prolong the entire operation time. Furthermore, if the cooling mold release agent is not sprayed immediately after dust removal, dust or dirt will accumulate again on the surface of the casting, which will lead to a decrease in cleaning effect and affect the quality and smoothness of the casting surface. like Figures 1 to 14 As shown, while the telescopic sleeve 61 reciprocates on the surface of the limiting guide rod 610, the limiting guide rod 610 causes the rotating gear 72 to rotate through the liquid control groove 71. At the same time as the rotating gear 72 rotates, it drives the functional bevel gear 75 to rotate synchronously through the reversing bevel gear 73. Because the telescopic sleeve 61 reciprocates up and down on the limiting guide rod 610, the rotation of the functional bevel gear 75 is a periodic bidirectional rotation. At the same time as the functional bevel gear 75 rotates, when the inclined surface of the teeth of the ratchet inner groove 712 abuts against the liquid control ratchet 711, the liquid control ratchet 711 moves towards the ratchet spring 710. When the straight surface of the ratchet inner groove 712 abuts against the liquid control ratchet 711, the liquid control ratchet 711 and the teeth of the ratchet inner groove 712 mesh with each other. When the inner groove 712 of the ratchet directly contacts the liquid control ratchet 711, the rotation of the functional bevel gear 75 drives the carrier plate 78 to rotate synchronously through the double groove plate 79. At the same time as the carrier plate 78 rotates, it drives the starter electric contact rod 77 fixedly connected to it to rotate synchronously. At the same time as the starter electric contact rod 77 rotates, the liquid control rotary block 715 rotates synchronously through the starter belt 721. At the same time as the liquid control rotary block 715 rotates, the liquid control rotary block 715 applies centrifugal force to the two starter liquid control blocks 718 inside it. Centrifugal force is an inertial force that appears in the rotating reference frame. It always points to the outside of the rotation axis and makes the object appear to be moving away from the rotation center. As a result, the two starter liquid control blocks 718 can move away from the center of the liquid control rotary block 715 and slide and compress the corresponding liquid control spring 717 inside the inner tank 716. Through the separation of the starter liquid control blocks 718, the cooling release agent loaded inside the liquid tank 719 can be connected with the speed-increasing liquid control block 713. Because the telescopic sleeve 61 reciprocates on the surface of the limiting guide rod 610, the reciprocating motion of the telescopic sleeve 61 causes the rotating gear 72 to also reciprocate on the surface of the liquid control groove 71. This makes the rotation of the starting electric contact rod 77 periodic and intermittent, and the flow of the cooling release agent also periodic and intermittent. This saves the amount of cooling release agent used and also prevents excessive cooling release agent from being sprayed inside the bottom mold.

[0033] Simultaneously with the rotation of the start-up contact rod 77, a signal is transmitted to the control panel, causing the control panel to energize the electric booster 720. The energized electric booster 720 applies pressure to the cooling release agent inside the liquid tank 719. Since liquids are incompressible, this force is transmitted to every part of the cooling release agent, generating an equivalent pressure throughout the entire cooling release agent. This pressurizes the cooling release agent, creating a pressure zone. At this point, the cooling release agent inside the liquid tank 719 can enter the liquid pipe 714 through the inner cavity of the speed-increasing control block 713. Because the inner cavity of the speed-increasing control block 713 is designed as a gradually narrowing funnel shape, and because the liquid tank 719... The internal cooling release agent is pressurized, and according to the continuity equation, the mass flow rate remains constant. The mass flow rate refers to the amount of liquid mass passing through the cross-section of the pipe per unit time. In a closed pipe system, the mass flow rate remains constant. When the cooling release agent passes through the wider area of ​​the inner cavity of the speed-increasing liquid control block 713, the cross-sectional area of ​​this area is larger, and the speed of the cooling release agent is slower. However, as the pipe gradually narrows, the cooling release agent needs to pass through a smaller cross-sectional area. In order to maintain a constant mass flow rate, the cooling release agent must pass through the narrower area of ​​the inner cavity of the speed-increasing liquid control block 713 at a higher speed, thereby accelerating the flow of the cooling release agent from the top to the bottom of the inner cavity of the speed-increasing liquid control block 713. The cooling release agent, carrying a certain initial velocity, is then released to the outside through the atomization hole at the bottom of the liquid pipe 714. Simultaneously, the telescopic sleeve 61 blows and draws air into the bottom mold, and the liquid pipe 714 is located in the air outlet of the telescopic sleeve 61. The atomized cooling release agent is then drawn by the airflow system created by the airflow from the telescopic sleeve 61. Because the length of the liquid pipe 714 is shorter than the length of the telescopic sleeve 61 at the slanted air outlet, the movement of the atomized cooling release agent is enveloped by the airflow. The airflow on the air outlet side... The atomized cooling release agent will first come into contact with the bottom mold to clean its surface. Then, the atomized cooling release agent will come into contact with the bottom mold, and with the up-and-down reciprocating movement of the telescopic sleeve 61, the atomized cooling release agent will be sprayed more widely on the bottom mold. This achieves simultaneous cleaning of dust and spraying of cooling release agent, avoiding the situation where dust or dirt accumulates again on the bottom mold surface due to the interval between cleaning and spraying. At the same time, the airflow system and the complex shape of the bottom mold are coordinated to ensure that the cooling release agent can be completely coated on the bottom mold. When the liquid control swivel block 715 stops rotating, it no longer applies centrifugal force to the liquid control block 718. Then, under the elastic extension of the liquid control spring 717, the two liquid control blocks 718 come into contact with each other, and the connection channel between the liquid tank 719 and the speed-up liquid control block 713 is cut off.

[0034] The locking assembly locks the top support platform 5 and the bottom support platform 2. In the sand casting process, when high-temperature molten metal is poured into the sand mold, uneven thermal expansion and contraction of the sand mold can occur, leading to the separation of the top mold and the bottom mold.

[0035] When the supporting platform 2 moves from the top of the working platform 1 to the bottom of the equipment door 3, the operator de-energizes the supporting platform 2 via the external control panel. The supporting platform 2 stops moving at the top of the working platform 1, and the internal components of the cleaning and sandblasting components cease operation. At this time, the operator electrically controls the electric telescopic rod 4 via the external control panel. The energized electric telescopic rod 4 drives the supporting top platform 5 and the top mold inside the supporting top platform 5 to move downwards, causing the top mold and bottom mold to overlap. During the overlap of the top and bottom molds, the two limiting blocks 85 abut against the top of the umbrella-shaped locking rod 81. Under the action of the shapes of the limiting blocks 85 and the umbrella-shaped locking rod 81, the two limiting blocks 85 move towards the two sides. The locking spring 84 on the corresponding side is separated and elastically compressed. When the limiting block 85 abuts against the bottom body of the umbrella-shaped locking rod 81, the two limiting blocks 85 are displaced towards the center of the umbrella-shaped locking rod 81 under the elastic extension of the locking spring 84. At this time, the limiting block 85 limits the vertical direction of the umbrella-shaped locking rod 81, thereby limiting the vertical direction of the bearing top platform 5 and the bearing bottom platform 2. This prevents the thermal expansion of the sand mold inside the top and bottom molds from causing the top and bottom molds to separate. This avoids the situation where the molten metal seeps into the separation gap of the sand mold due to the separation of the top and bottom molds, resulting in uneven metal flow. This ensures that the dimensions of the casting meet the design requirements and improves the production quality of the casting.

[0036] Among them, the heat absorption effect of the cleaning component when the supporting base 2 moves away from the equipment door 3: When demolding is required, the high temperature inside the mold conducts heat to the outside, causing the surrounding air to heat up rapidly and rise. Harmful substances in the hot air are released into the surrounding environment, causing air pollution. These pollutants negatively impact air quality, causing respiratory problems, eye irritation, and other health issues. Furthermore, the rapid rise in ambient air temperature can adversely affect nearby equipment and machinery. The high temperature environment can cause electronic devices to overheat, leading to malfunctions or damage. At the same time, the high temperature will evaporate the lubricant in the surrounding machinery. In a high-temperature environment, the liquid components in the lubricant become more active when heated, making it easier for the volatile components in the lubricant to change from a liquid to a gaseous state and then evaporate. When the lubricant evaporates, the temperature inside the machinery will rise, exceeding the tolerance range of the mechanical parts, leading to mechanical failure or damage. In addition, after the lubricant evaporates, the deposits will remain on the surface of the mechanical parts. These deposits will accumulate on the friction surfaces, forming hard particles or gel-like substances, increasing friction and wear between parts, leading to mechanical failure.

[0037] like Figures 1 to 16 As shown, after sand casting is completed, the operator electrically controls the reverse displacement of the bearing base 2 via an external control panel. During this process, since the locking assembly only controls the vertical limit of the bearing base 2 and the bearing top platform 5, the two limit blocks 85 separate when the bearing base 2 moves in the reverse direction, causing the bearing base 2 to drive the bottom mold to move in the reverse direction. At the same time, due to the presence of the casting between the top mold and the bottom mold, the top mold and the bottom mold can move synchronously in the horizontal direction. Since the direction in which the top mold is installed on the bearing top platform 5 is towards the side of the working base 1 away from the equipment door 3, the bearing base 2 synchronously drives the top mold and the bottom mold to move towards the side of the working base 1 away from the equipment door 3. Then, the operator uses the external control panel to retract the electric telescopic rod 4 to lift the bearing top platform 5. While the support platform 2 is displaced in the opposite direction, the cleaning component on the side near the liquid control groove 71 uses a shaft fan 66 to draw air towards the center of the support platform 2, and the cleaning component on the side away from the liquid control groove 71 uses a shaft fan 66 to push air flow towards the center of the support platform 2, thus forming an air circulation system in the opposite direction. The hot air caused by the heat emitted by the top mold and bottom mold on the support platform 2 is disturbed by the airflow and enters the telescopic sleeve 61 on the side near the liquid control groove 71, and is discharged to the outside through the air intake pipe 62. At the same time, the spraying component sprays cooling release agent towards the bottom mold. The atomization effect cools the hot air, and all the air discharged to the outside through the air intake pipe 62 is cooled, ensuring the safety of the surrounding equipment. At the same time, by absorbing the hot air, the production safety of the surrounding personnel is ensured, which has a positive effect on the sand casting work.

[0038] At this point, the staff used the external control panel to de-energize the support platform 2 and remove the casting from the bottom mold, thus completing the entire process.
