Description

Technical Field

[0001] The invention relates to the technical field of casting, in particular to an integrated casting device for an oil pan of an automobile engine. Background Art

[0002] Traditional automobile engine oil pan casting equipment mostly uses a fixed mold combined with high-pressure die casting or gravity casting. The process usually requires precise adjustment of multiple links such as melt injection, mold closing, cooling and unloading through a PLC digital control system. However, there are significant disadvantages: first, the PLC control system is complex in design and requires professional programming and maintenance, resulting in high initial investment and subsequent maintenance costs of the equipment; second, the unloading process usually requires manual assistance or additional mechanical operation, which is not only inefficient, but may also damage the mold or product due to improper operation; in addition, the control system is too dependent on digital modules. Once a failure occurs, the repair cycle is long and the cost is high. In contrast, this equipment innovatively uses electromagnet on-off control to replace the PLC digital system. The entire process can be completed only through the combination of simple magnetic force and mechanical structure, which greatly simplifies the control method and solves many problems in traditional technology.

The center position of the circle inside the gear ring disk 120 is rotated with a center gear 124. The center gear 124 and the gear ring disk 120 are meshed and transmitted through three planetary gears 121. The three planetary gears 121 are rotatably mounted on a planetary gear mounting disk 122. A permanent magnet ring 123 is fixedly mounted at the edge of the planetary gear mounting disk 122.Two stacked and coaxially arranged first limiting electromagnets 125 and second limiting electromagnets 126 are fixedly installed on the lower surface of the rotating seat 119, wherein the permanent magnet ring 123 is rotatably installed on the inner rings of the first limiting electromagnet 125 and the second limiting electromagnet 126, and the permanent magnet ring 123 is magnetically matched with the first limiting electromagnet 125 and the second limiting electromagnet 126, wherein the output shaft of the drive motor 128 passes through the planetary gear mounting plate 122 and is fixedly matched with the center gear 124, the planetary gear mounting plate 122 is rotationally matched with the output shaft of the drive motor 128, and the gear ring plate 120 is rotationally matched with the planetary gear mounting plate 122.

[0019] The working principle of the integrated casting equipment for the oil pan of an automobile engine disclosed in the present invention is as follows: a heating wire is embedded in the injection groove 102, the injection channel 104, the concave mold 110 and the convex mold 108 inside the formed conical rotating support body 101. When in use, the drive motor 128 and the first limiting electromagnet 125 are started (the magnetic force generated by the first limiting electromagnet 125 is greater than that of the second limiting electromagnet 126, and the installation positions of the first limiting electromagnet 125 and the second limiting electromagnet 126 can be interchanged). After the first limiting electromagnet 125 is started, a magnetic force is generated, which attracts the permanent magnet ring 123 through the magnetic force to prevent the permanent magnet ring 123 from rotating. The permanent magnet ring 123 cannot rotate, and the three planetary gears 121 on the planetary gear mounting plate 122 cannot rotate. At this time, the output of the drive motor 128 is The output shaft drives the center gear 124, and the center gear 124 drives the gear ring disk 120 to rotate through the planetary gear 121. The rotation of the gear ring disk 120 drives the forming conical rotating support body 101 to rotate. The rotation of the forming conical rotating support body 101 will drive the injection groove 102 and the injection channel 104 to rotate. At this time, the molten metal is poured into the funnel 131, and the molten metal inside the funnel 131 flows into the injection groove 102 through the injection pipe 130, and then flows into the injection channel 104. At this time, the molten metal will rotate with the forming conical rotating support body 101, and the rotating molten metal will be subjected to centrifugal force. At this time, the molten metal will flow to the gap between the concave mold 110 and the convex mold 108 under the action of centrifugal force until the gap is filled. During this filling process, the air will be discharged through the exhaust hole 109 on the top. When the formed conical rotating support body 101 rotates, it will also drive the L-shaped bracket 134 and the wing-shaped counterweight block 133 to rotate. Therefore, when starting the first limiting electromagnet 125, it is necessary to make the top fitting electromagnet 129 in a power-off state (that is, the top fitting electromagnet 129 and the second limiting electromagnet 126 are powered on and off synchronously). Then, the rotation of the wing-shaped counterweight block 133 will drive the L-shaped bracket 134 to swing on the L-shaped bracket rotating seat 103 under the centrifugal force, thereby pulling the elastic pull strip 132 to deform. The outward swing of the L-shaped bracket 134 will press down the push rod 118, and the push rod 118 will press the male mold 108 on the female mold 110, so that the two are sealed. The wing-shaped counterweight 133 will also be subjected to downward pressure during the rotation process (the curvature of the upper surface of the wing-shaped counterweight 133 is smaller than the curvature of the lower surface). The relative movement between the wing-shaped counterweight 133 and the air will cause the pressure on the upper surface of the wing-shaped counterweight 133 to be greater than the pressure on the lower surface. At this time, it will be subjected to downward pressure, thereby squeezing the male mold 108.

[0020] The next step is to stop all the heating wires from working, and then continue to maintain the speed of the formed conical rotating support 101, wait for the metal liquid to cool, and then cut off the power to the first limiting electromagnet 125. At this time, the first limiting electromagnet 125 no longer magnetically attracts the permanent magnet ring 123, which will cause the planetary gear mounting plate 122 and the permanent magnet ring 123 to rotate, so the power on the drive motor 128 will be released to the planetary gear mounting plate 122 (because the rotation of the formed conical rotating support 101 is a load, relative to the rotation of the planetary gear mounting plate 122 In general, the resistance at the planetary gear mounting plate 122 is much smaller than the resistance of the formed conical rotating support body 101), so at this time the formed conical rotating support body 101 will not be driven by the output shaft of the driving motor 128 (it will hardly be driven because of the friction), but will slowly decelerate and rotate under its own inertia. When the centrifugal force and the upper and lower pressure difference exerted on the wing-shaped counterweight block 133 cannot make the L-shaped bracket 134 overcome the elastic force of the elastic pull bar 132, it will swing toward the top fitting electromagnet 129 under the pull of the elastic pull bar 132, and then the wing-shaped counterweight block 13 3 is fitted with the top fitting electromagnet 129, and the top fitting electromagnet 129 and the second limiting electromagnet 126 are started at this time. Since the magnetic force of the second limiting electromagnet 126 is smaller than that of the first limiting electromagnet 125, the permanent magnet ring 123 cannot be completely attracted by the magnetic force, resulting in the permanent magnet ring 123 being only hindered by the magnetic force of the second limiting electromagnet 126. Therefore, the rotation of the permanent magnet ring 123 is hindered, the planetary gear mounting plate 122 is also hindered, and the revolution of the planetary gear 121 is hindered. At this time, the output shaft of the driving motor 128 is driven to the formed conical rotating support body 1 01 will reduce the transmission efficiency, because part of the power is used to drive the planetary gear mounting plate 122 to rotate, resulting in a decrease in the rotation speed of the formed conical rotating support 101 (relative to when the first limiting electromagnet 125 is activated). At this time, the centrifugal force that drives the male mold 108 to rotate when the formed conical rotating support 101 rotates will compress the male mold reset spring 116, and at the same time, the male mold support slide bar 115 and the support arm 117 slide relative to each other, and the male mold 108 will be pulled out of the female mold 110, and then the formed oil pan will remain in the female mold 110. At this time, the unloading electromagnet 111 needs to be powered off (first start the second limiting electromagnet 126 and then disconnect the unloading electromagnet 111, with an interval of 2-3 seconds in between). When the unloading electromagnet 111 is powered off, it will lose its magnetic force, thereby losing its suction to the bottom contact plate 114. The top contact plate 113, the unloading push plate 112, and the bottom contact plate 114 will slide outward under the action of centrifugal force. At the same time, when the male mold supporting slide bar 115 contacts the top contact plate 113, it will also be subjected to the centrifugal force from the rotation of the male mold 108.At this time, the bottom contact plate 114 will squeeze the discharge ejector pin 105, and the discharge ejector pin 105 will squeeze the discharge return spring 106, so that the discharge return spring 106 is compressed, and the discharge ejector pin 105 is pushed into the female mold 110, and the oil pan that has been cooled and formed in the female mold 110 is ejected, so that the outer surface of the oil pan is separated from the inner wall of the female mold 110. At this time, it is still in a rotating state, so the formed oil pan will be separated from the female mold 110 and the male mold 108 by the centrifugal force. Finally, the drive motor 128 and the second limiting electromagnet 126 are stopped, and the discharge electromagnet 111 is started again, so that all movable parts are reset, and then the next oil pan is formed.
