Description

Technical Field

[0001] The present application relates to the field of casting technology, and in particular to a casting mold slider demoulding mechanism. Background Art

[0002] A mold is a tool used to make shaped objects. During the casting process, a demolding mechanism is usually required to smoothly remove the cast mold, thereby facilitating subsequent processing of the mold.

[0003] Some existing casting and demolding mechanisms are mainly composed of a die, a punch, a core shooter and an ejector. When in use, the die and the punch are first closed to form a cavity in the shape of a mold. Then, the core shooter injects a molten liquid casting material into the cavity. After a period of time, the material cools into a solid and forms a mold. Then, the die and the punch are opened, and the die drives the formed mold to flip half a circle so that the bottom surface of the die faces upward. Finally, the ejector arranged on the bottom surface of the die is extended to contact and push the mold so that the mold is separated from the die. Through the above actions, the casting and demolding operations of the mold are realized.

[0004] However, in the above process, since the ejector is arranged at the bottom surface of the die, in order to ensure the molding quality of the mold, the ejector needs to form a sealed sliding connection with the die. During long-term use, the ejector is prone to sealing failure, resulting in part of the casting material entering the gap between the ejector and the die, ultimately affecting the molding quality of the mold and the normal operation of the ejection mechanism. Summary of the invention

[0005] The present application proposes a casting mold slider demoulding mechanism, which has the advantage of preventing the demoulding mechanism from being affected by the casting material, and is used to solve the problem that the casting material affects the mold molding quality and the normal operation of the demoulding mechanism.

[0006] To achieve the above-mentioned purpose, the present application adopts the following technical scheme: a casting mold slider demoulding mechanism, comprising: a top plate, a bottom plate is arranged below the top plate, vertical plates are fixed on both sides of the position between the top plate and the bottom plate, a male mold is arranged below the top plate and between the vertical plates on both sides, a female mold is arranged below the male mold, when the male mold and the female mold are closed, a cavity is formed between the male mold and the female mold for molding the mold, a flip mechanism is arranged inside the vertical plate, the flip mechanism is connected to the female mold, and is used to drive the female mold to rotate half a circle and reset; A No. 2 telescopic rod is fixedly installed at the center position of the upper side of the bottom plate, a slider body is arranged between the No. 2 telescopic rod and the concave mold, the output rod end of the No. 2 telescopic rod is fixedly connected to the center position of the bottom surface of the slider body, a moving mechanism is arranged inside the slider body, and pressure plates are arranged around the slider body, and the moving mechanism is connected to the pressure plate to drive the pressure plate to contact and support the inner wall of the mold.

[0007] Furthermore, a telescopic rod No. 1 is fixedly installed on both sides of the top plate, and the output rod end of the telescopic rod No. 1 is fixedly connected to the upper side surface of the punch. A core shooting tube is fixedly installed on the upper side surface of the punch and between the telescopic rods No. 1 on both sides, and the lower side opening of the core shooting tube is opened on the lower side surface of the punch.

[0008] Furthermore, the flipping mechanism includes a rotating shaft and a motor. The side of the die facing the corresponding vertical plate is fixedly installed with a rotating shaft, the inside of one side vertical plate is fixedly installed with a motor, the other end of the rotating shaft away from the motor is rotatably connected with the corresponding vertical plate, and the other end of the rotating shaft close to the motor is fixedly connected with the output end of the motor.

[0009] Furthermore, the moving mechanism includes an installation cavity, an air pump, a sliding cavity, a No. 1 through hole, a slide plate and a connecting plate. An installation cavity is opened at the center position inside the slider body, an air pump is fixedly installed in the installation cavity, the air pump connects the installation cavity with the external environment, sliding cavities are opened inside the slider body and around the installation cavity, a No. 1 through hole is opened inside the slider body and between the sliding cavity and the installation cavity, a slide plate is sealed and movably installed in the sliding cavity, a connecting plate is fixedly installed on the side of the slide plate facing the corresponding pressure plate, the other side of the connecting plate extends out of the slider body and is fixedly connected to the corresponding pressure plate, and the connecting plate is slidably connected to the slider body.

[0010] Furthermore, a contact piece is fixedly mounted on the side of the pressure plate facing away from the slider body, and the contact piece is made of rubber material.

[0011] Furthermore, the contact piece is a suction cup structure.

[0012] Furthermore, an airbag is provided in the cavity of the sliding cavity and at a position where the sliding plate is back to the corresponding pressure plate, one side of the airbag is fixedly connected to the sliding plate, and the other side of the airbag is fixedly connected to the inner wall of the sliding cavity, and a No. 2 through hole is commonly provided inside the sliding plate, inside the connecting plate and inside the pressure plate, one side of the No. 2 through hole is connected to the inner cavity of the airbag, and the other side opening of the No. 2 through hole is provided on the side of the pressure plate back to the sliding block body, and the other side opening of the No. 2 through hole is within the area surrounded by the contact piece.

[0013] Furthermore, a pressure sensor is fixedly installed at the center position of the upper side surface of the slider body, and the pressure sensor forms a remote control connection with the second telescopic rod.

[0014] This application has the following beneficial effects: The present application provides a casting mold slider demolding mechanism, which is provided with a No. 2 telescopic rod, a slider body and a pressure plate. When the female mold drives the formed mold to flip half a circle, the No. 2 telescopic rod drives the slider body and the pressure plate to extend into the inner cavity of the mold. After that, the pressure plate moves and applies an external support force to the inner wall of the mold. Then, the No. 2 telescopic rod drives the slider body and the pressure plate to move downward and reset. Through the above-mentioned external support force, the mold is driven by the pressure plate to move downward synchronously. Since the pressure plate and the female mold in the device are separately arranged, the casting material will not affect the pressure plate during the casting process, thereby ensuring that the molding quality of the mold and the normal operation of the demolding mechanism are not affected.

[0015] Through the setting of the pressure plate and the contact piece, when the pressure plate applies external support force to the inner wall of the mold, the contact piece will be located between the two. Since the contact piece is made of rubber material, the contact force between the pressure plate and the inner wall of the mold is increased, making it easier for the pressure plate to drive the mold out of the die. At the same time, the squeezed contact piece will apply suction to the inner wall of the mold, so that the contact force between the pressure plate and the inner wall of the mold is further increased, thereby further promoting the smooth demolding of the mold.

[0016] Through the arrangement of the pressing plate, the contact piece and the airbag, when the pressing plate applies an external supporting force to the inner wall of the mold, the airbag will be stretched, allowing the airbag to further take in air. Afterwards, when the pressing plate is reset, the gas in the airbag will be guided into the area surrounded by the contact piece, prompting the contact piece to quickly detach from the inner wall of the mold. Through the above action, when the pressing plate is reset, the suction force between the contact piece and the inner wall of the mold is not easy to cause deformation of the mold wall.

[0017] Through the arrangement of the slider body and the pressure sensor, in the process that the No. 2 telescopic rod drives the slider body to extend into the mold cavity, the pressure sensor arranged on the upper side of the slider body synchronously enters the mold cavity. Afterwards, when the pressure sensor contacts the mold and rotates to the upper bottom surface, the pressure sensor outputs a signal to the No. 2 telescopic rod, causing the No. 2 telescopic rod to stop running. Through the above action, the pressure plate and the contact piece can extend into the uppermost side of the mold cavity, so that the external support force applied by the pressure plate can be better applied to the mold, thereby further promoting the smooth demolding of the mold. At the same time, when the pressure plate is reset, the suction between the contact piece and the inner wall of the mold is less likely to cause deformation of the mold wall.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0022] Embodiment 1 See also Figure 1 and Figure 2A casting mold slider demoulding mechanism comprises a top plate 1, a bottom plate 2 is arranged below the top plate 1, vertical plates 3 are arranged on both sides of the position between the top plate 1 and the bottom plate 2, the upper side of the vertical plate 3 is welded and fixed to the lower side of the top plate 1, and the lower side of the vertical plate 3 is welded and fixed to the upper side of the bottom plate 2, a punch 4 is arranged below the top plate 1 and between the vertical plates 3 on both sides, a No. 1 telescopic rod 5 (such as the electric control telescopic rod in the prior art) is fixedly installed on both sides of the inside of the top plate 1, the output rod end of the No. 1 telescopic rod 5 is fixedly connected to the upper side of the punch 4, a core shooting tube 6 is fixedly installed on the upper side of the punch 4 and between the No. 1 telescopic rods 5 on both sides, the lower side opening of the core shooting tube 6 is opened on the lower side of the punch 4, and a die 7 is arranged below the punch 4. When the punch 4 and the die 7 are closed, a cavity is surrounded by the punch 4 and the die 7 for forming a mold 8.

[0023] When in use, the No. 1 telescopic rod 5 drives the punch 4 to move downward until the punch 4 and the die 7 are closed. Then, the core shooting machine injects the molten liquid casting material into the core shooting tube 6 so that the casting material fills the cavity. After a period of time, the casting material in the cavity cools to form a mold 8.

[0024] See also Figure 1 and Figure 2 A rotating shaft 9 is provided on the side of the die 7 facing the corresponding vertical plate 3, a motor 10 is fixedly installed inside the vertical plate 3 on one side, one end of the rotating shaft 9 on one side is fixedly connected to the die 7, the other end of the rotating shaft 9 on one side is rotationally connected to the corresponding vertical plate 3, one end of the rotating shaft 9 on the other side is fixedly connected to the die 7, and the other end of the rotating shaft 9 on the other side is fixedly connected to the output end of the motor 10.

[0025] After the mold 8 is cooled and formed, the No. 1 telescopic rod 5 drives the punch 4 to move upward, and then the motor 10 drives the rotating shaft 9 to rotate, so that the die 7 drives the mold 8 to rotate half a circle, thereby facilitating the subsequent demoulding mechanism to drive the mold 8 out of the die 7.

[0026] See also Figure 1-Figure 5A second telescopic rod 11 (such as an electric telescopic rod in the prior art) is fixedly installed at the center position of the upper side of the bottom plate 2, a slider body 12 is arranged between the second telescopic rod 11 and the concave mold 7, the output rod end of the second telescopic rod 11 is fixedly connected to the center position of the bottom surface of the slider body 12, a mounting cavity 13 is opened at the center position inside the slider body 12, an air pump 14 is fixedly installed in the mounting cavity 13, the air pump 14 connects the mounting cavity 13 with the external environment, and sliding cavities 15 are opened inside the slider body 12 and around the mounting cavity 13. A through hole No. 1 is provided inside the body 12 and between the sliding cavity 15 and the installation cavity 13. The through hole No. 1 connects the corresponding sliding cavity 15 and the installation cavity 13. A slide plate 17 is sealed and slidably installed in the cavity of the sliding cavity 15. Pressure plates 18 are provided around the slider body 12 and at positions corresponding to the slide plates 17. A connecting plate 19 is fixedly installed on the side of the slide plate 17 facing the corresponding pressure plate 18. The other side of the connecting plate 19 extends out of the slider body 12 and is fixedly connected to the corresponding pressure plate 18. The connecting plate 19 is slidably connected to the slider body 12.

[0027] After the die 7 drives the mold 8 to flip half a circle, the second telescopic rod 11 drives the slider body 12 and the pressure plate 18 to extend into the inner cavity of the mold 8 (the extension amount of the second telescopic rod 11 can be set as required), and then the air pump 14 is activated to draw outside air into the installation cavity 13 (the air delivery and exhaust volume of the air pump 14 can be controlled by controlling the running time of the air pump 14), and enter the sliding cavity 15 through the first through hole 16, so that the corresponding slide plate 17 pushes the pressure plate 18 to move through the connecting plate 19, and finally makes the pressure plate 18 contact the mold 8 and exert an external support force on the inner wall of the mold 8 (because the wall of the mold 8 fits the inner wall of the die 7, the above-mentioned external support force will not drive the mold 8 to deform in shape), and then the second telescopic rod 11 drives the slider body 12 and the pressure plate 1 8 moves down and resets, and the mold 8 is driven by the pressure plate 18 to move downward synchronously through the above-mentioned external support force. Since the pressure plate 18 and the concave mold 7 in the present device are separately arranged, the casting material will not affect the pressure plate 18 during the casting process, thereby ensuring that the molding quality of the mold 8 and the normal operation of the demoulding mechanism are not affected. Afterwards, when the No. 2 telescopic rod 11 is reset, the air pump 14 is allowed to discharge the above-mentioned drawn gas into the external environment, so that the above-mentioned structure is reset, and the bottom surface of the mold 8 (the horizontal surface of the mold 8) contacts the upper side surface of the slider body 12. In this process, since the distance between the slider body 12 and the bottom surface of the mold 8 is relatively close, the impact force of the mold 8 when it falls is relatively weak. Through the above-mentioned action, it is avoided that the mold 8 falls a long distance, which may cause damage to the mold 8.

[0028] See also Figure 1-Figure 5 A contact piece 20 is fixedly mounted on the side of the pressure plate 18 facing away from the slider body 12 , and the contact piece 20 is made of rubber material.

[0029] When the pressure plate 18 applies external support force to the inner wall of the mold 8, the contact piece 20 will be located between the two. Since the contact piece 20 is made of rubber material, the contact force between the pressure plate 18 and the inner wall of the mold 8 is increased, making it easier for the pressure plate 18 to drive the mold 8 out of the die 7.

[0030] The contact member 20 is a suction cup structure.

[0031] The squeezed contact member 20 exerts suction force on the inner wall of the mold 8, so that during the subsequent downward movement of the pressing plate 18, the contact force between the pressing plate 18 and the inner wall of the mold 8 is further increased, thereby further promoting smooth demolding of the mold 8.

[0032] Embodiment 2 See also Figure 1-Figure 7 This embodiment is a further improvement of the first embodiment, and the improvement lies in that an airbag 21 is arranged in the cavity of the sliding cavity 15 and at a position where the sliding plate 17 faces away from the corresponding pressure plate 18. One side of the airbag 21 is fixedly connected to the sliding plate 17, and the other side of the airbag 21 is fixedly connected to the inner wall of the sliding cavity 15. A second through hole 22 is commonly provided inside the sliding plate 17, inside the connecting plate 19 and inside the pressure plate 18. One side of the second through hole 22 is connected to the inner cavity of the airbag 21, and the other side of the opening of the second through hole 22 is provided on the side of the pressure plate 18 facing away from the slider body 12, and the other side of the opening of the second through hole 22 is within the area surrounded by the contact member 20.

[0033] In the process of the above-mentioned pressing plate 18 applying external supporting force to the inner wall of the mold 8, the slide plate 17 will stretch the airbag 21, so that the airbag 21 sucks the outside air through the No. 2 through hole 22. Afterwards, when the pressing plate 18 is reset, the corresponding slide plate 17 will squeeze the airbag 21, so that the air in the airbag 21 enters the area surrounded by the contact piece 20 through the No. 2 through hole 22, thereby prompting the contact piece 20 that adsorbs the inner wall of the mold 8 to quickly detach from the inner wall of the mold 8. Through the above-mentioned action, when the pressing plate 18 is reset, the suction force between the contact piece 20 and the inner wall of the mold 8 is not easy to cause deformation of the wall of the mold 8.

[0034] See also Figure 1-Figure 7 A pressure sensor 23 is fixedly installed at the center position of the upper side of the slider body 12, and the pressure sensor 23 forms a remote control connection with the second telescopic rod 11 (when the pressure sensor 23 senses pressure, the pressure sensor 23 outputs a signal to the second telescopic rod 11, causing the second telescopic rod 11 to stop running).

[0035] When the second telescopic rod 11 drives the slider body 12 to extend into the inner cavity of the mold 8, the pressure sensor 23 simultaneously enters the inner cavity of the mold 8. Afterwards, when the pressure sensor 23 contacts the mold 8 and rotates to the upper bottom surface, the pressure sensor 23 outputs a signal to the second telescopic rod 11, causing the second telescopic rod 11 to stop running. Through the above action, the pressure plate 18 and the contact member 20 can extend into the uppermost side of the inner cavity of the mold 8, so that the external support force applied by the pressure plate 18 can be better applied to the mold 8 (the contact position between the above pressure plate 18 and the mold 8 is closer to the connection between the side wall and the bottom wall of the mold 8, so that the external support force applied by the pressure plate 18 to the side wall of the mold 8 is not easy to deform the side wall of the mold 8), thereby further promoting the smooth demolding of the mold 8. At the same time, when the pressure plate 18 is reset, the suction between the contact member 20 and the inner wall of the mold 8 is less likely to cause deformation of the wall of the mold 8.
