Description

Technical Field

[0001] The invention relates to the field of casting, and in particular to an integrated device and process for shelling and blanking water glass in investment casting. Background Art

[0002] Since water glass has good heat resistance, alkali resistance, strong adhesion, and poor water resistance, molds made of water glass are often used in the foundry industry. The molds made of water glass have fewer defects in the castings, and its poor water resistance can also be used during demolding to complete more convenient and quick demolding.

[0003] At present, the common demoulding method is to manually cool the poured mold, then remove the mold on the surface of the casting by thermal processing, and finally transfer the casting to the storage area. In this process, there is a lack of systematic work flow, resulting in the inability to achieve fast and effective coordination from fixing the mold to pouring and finally to demoulding and unloading, which affects the improvement of work efficiency. In addition, the unloading process requires manual transfer of the casting, which is time-consuming and labor-intensive. For this reason, this scheme proposes an integrated equipment and process for shelling and unloading of water glass in investment casting. Summary of the invention

[0004] The invention provides an integrated device and process for shelling and blanking water glass during investment casting, which solves the problems of low efficiency and failure of automatic blanking of water glass shelling and blanking in the prior art.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] The cooling mechanism comprises a mounting frame arranged on one side of the tray, two side plates installed on the mounting frame and a cooling pipe installed on the outer wall of one side opposite to the two side plates, and a cooling space is formed between the two side plates.

[0009] Through the above technical solution, not only can the final steps of loading, pouring, cooling and demoulding be completed in sequence conveniently and labor-savingly, but also the unloading can be carried out automatically after the demoulding is completed, thereby reducing the difficulty of production.

[0010] As a further improvement of the above scheme, the support plate is arranged along the radial direction of the placing disk, and the long sides of both sides of the support plate away from the center of the placing disk are rotatably connected to the side wall of the mounting groove, and a limiting plate for supporting the support plate is fixed on the inner wall of the mounting groove close to the center of the placing disk.

[0011] Through the above technical solution, the limiting plate is used to lift the support plate.

[0012] As a further improvement of the above solution, two clamping plates are provided on the top surface of the support plate, and the two clamping plates are movably connected to the support plate through elastic members, and the elastic members cooperate with the mounting grooves.

[0013] Through the above technical solution, the mold can be effectively prevented from moving by using a clamping plate to clamp the periphery of the mold.

[0014] As a further improvement of the above scheme, a buffer groove is provided on the top surface of the support plate, and a spring hole is provided on the side of the buffer groove close to the center of the support plate. The elastic member includes a connecting plate movably arranged in the buffer groove, a buffer column fixed on the outer wall of the side of the movable plate close to the spring hole, and an abutment plate fixed on the outer wall of the side of the movable plate away from the spring hole. One end of the buffer column extends into the spring hole and is fixed with a buffer spring, and the other end of the buffer spring is fixedly connected to the inner wall of the spring hole, one end of the abutment plate extends into the mounting groove, and the end of the abutment plate located in the mounting groove is a right-angled triangle mechanism with the inclined surface facing downward, and the abutment plate cooperates with the mounting groove.

[0015] Through the above technical solution, the clamping plates can be automatically opened outward when the support plate is lifted, and when the support plate enters the placement groove, the two clamping plates can be automatically driven to approach each other.

[0016] As a further improvement of the above scheme, a sliding groove for installing a reset member is opened on the outer periphery of the support column, and the reset member includes a sleeve rod fixed in the sliding groove along the axial direction of the support column and a reset spring movably sleeved on the outside of the sleeve rod, and the movable plate is movably sleeved on the outside of the sleeve rod, the top of the reset spring is fixedly connected to the top of the sliding groove, and the bottom of the reset spring is fixedly connected to the top surface of the movable plate.

[0019] The above technical solution ensures that the mold can pass smoothly between the two side plates.

[0020] As a further improvement of the above scheme, an air pipe connected to the cooling pipe is fixed on the top surface of the mounting frame, and the air pipe is connected to the external cold air pipe through a pipeline. The number of cooling pipes on the two side panels is at least two, and a plurality of air outlet holes are provided on the cooling pipe.

[0021] Through the above technical solution, an external cold air pipe is used to transport cold air into the air pipe, and the cold air then enters the cooling pipe and is then blown out from the air outlet, thereby accelerating the cooling of the mold.

[0023] S1. Assemble the water glass mold, place it on the top surface of the support plate at the loading position, and clamp the mold between two clamping plates, and then wait for pouring;

[0024] S2, start the driving motor to drive the placement plate to rotate, and the placement plate stops for a period of time every time it rotates to a station, driving the mold to turn to the pouring position, cooling position and unloading position in turn;

[0026] S4. When the casting rotates to the unloading position, remove the mold, then start the telescopic part to extend, lift the pallet upward, and the casting on the top of the pallet falls from the pallet to complete the unloading.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1.

[0039] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0040] Embodiment 1:

[0041] Please combine Figure 1 - Figure 6 The present embodiment is an integrated device for shelling and unloading water glass in investment casting, comprising a support plate 10, a support column 1 rotatably connected to the support plate 10, and a placement tray 2 fixed on the top of the support column 1. A plurality of mounting grooves 9 are provided on the edge of the top surface of the placement tray 2. A support plate 8 is rotatably connected in the mounting groove 9. The support plate 8 is arranged along the radial direction of the placement tray 2, and the two sides of the long sides of the support plate 8 away from the center of the placement tray 2 are rotatably connected to the side wall of the mounting groove 9 by rotation. A limiting plate 17 for supporting the support plate 8 is fixed on the inner wall of the side of the mounting groove 9 close to the center of the placement tray 2. The limiting plate 17 is arranged to support one end of the support plate 8 close to the center of the placement tray 2. After the end of the placement tray 8 close to the center of the placement tray 2 is lifted upward, the material on the top surface of the support plate 8 can be poured down.

[0042] A material unloading mechanism is installed in the mounting groove 9, and a loading position, a pouring position, a cooling position and a material unloading position are arranged on the placing plate 2. A cooling mechanism is installed on the cooling position. The mold is placed on the support plate 8 at the loading position, the material is poured into the mold at the pouring position, and the mold is cooled during cooling. Finally, the shelling of the mold and the unloading of the casting are completed at the material unloading position.

[0043] The unloading mechanism includes a connecting rod 11 hinged on the bottom surface of the support plate 8 and a movable plate 14 movably mounted on the outer periphery of the support column 1 through a reset member. A connecting groove 16 is provided on the bottom surface of the mounting groove 9. The bottom of the connecting rod 11 passes through the connecting groove 16 and is hinged to one end of the movable plate 14. A telescopic member 12 located at the unloading position is installed on the top surface of the support plate 10. The telescopic member 12 cooperates with the movable plate 14. A slide groove 15 for installing a reset member is provided on the outer periphery of the support column 1. The reset member includes a sleeve rod 13 fixed in the slide groove 15 along the axial direction of the support column 1 and a sleeve 13 movably mounted on the sleeve rod. The return spring outside 13, the movable plate 14 is movably sleeved on the outside of the sleeve rod 13, the top of the return spring is fixedly connected to the top of the slide groove 15, and the bottom of the return spring is fixedly connected to the top surface of the movable plate 14. When there is no external force acting on the movable plate 14, the movable plate 14 abuts against the bottom of the slide groove 15 under the action of the return spring. At this time, the support plate 18 is in a flat state, and when the telescopic member 12 is extended, the movable plate 14 located on the unloading position will be pushed up, so that one end of the support plate 8 located on the unloading position can be lifted upward, thereby completing the unloading process.

[0044] The cooling mechanism includes a mounting frame 3 arranged on one side of the placement plate 2, two side panels 4 installed on the mounting frame 3 and a cooling pipe 5 installed on the outer wall of the side opposite to the two side panels 4. A cooling space is formed between the two side panels 4. Both side panels 4 are arc-shaped panels, and both side panels 4 are coaxially arranged with the placement plate 2. An air supply pipe 6 connected to the cooling pipe 5 is fixed on the top surface of the mounting frame 3. The air supply pipe 6 is connected to the external cold air pipe through a pipeline. The number of cooling pipes 5 on the two side panels 4 is at least two, and a plurality of air outlets are provided on the cooling pipe 5. As the placement plate 2 rotates, the cast mold will rotate into the cooling space, and the cold air transported by the external cold air pipe will be input into the cooling pipe 5 and then discharged from the air outlet, thereby cooling the mold.

[0045] The implementation principle of this embodiment is as follows: the support column 1 rotates intermittently under the drive of the driving motor. At the loading position, the mold is placed on the support plate 8. Then, under the rotation of the placement plate 2, the mold will rotate to the pouring position. At this time, the raw material is poured into the mold. After the pouring is completed, the placement plate 2 rotates again, so that the mold after pouring is rotated to the cooling position. The cold air discharged from the cooling pipe 5 can accelerate the cooling of the mold. Then, during the rotation of the placement plate 2 again, the cooled mold rotates to the unloading position. After the placement plate 2 stops again, the mold is first removed from the outside of the casting, and then the telescopic member 12 is started to extend. After the telescopic member 12 is extended, it abuts against a moving plate 14 in a unloading mechanism directly above it, and the moving plate 14 will be lifted upward. After the moving plate 14 rises, it will drive one end of the support plate 8 located on the unloading position to lift upward, so that the casting on the support plate 8 falls from the support plate 8, thereby completing the unloading.

[0046] During the rising process of the movable plate 14, the return spring is also compressed. When the telescopic member 12 contracts, the return spring gradually recovers its deformation, thereby driving the movable plate 14 to move downward, and then the support plate 8 can be gradually rotated downward until it is flat again. The bottom surface of the flattened support plate 8 falls on the limit plate 17, so that it can be supported by the limit plate 17.

[0047] Embodiment 2:

[0048] Combination Figure 1 - Figure 6 On the basis of embodiment 1, the present embodiment is further improved in that: two clamping plates 7 are provided on the top surface of the support plate 8, the clamping plates 7 are arc-shaped plates, the two clamping plates 7 are movably connected to the support plate 8 through elastic members, a placement space is formed between the two clamping plates 7, the elastic member cooperates with the mounting groove 9, a buffer groove 18 is provided on the top surface of the support plate 8, a spring hole 20 is provided on the side of the buffer groove 18 close to the center of the support plate 8, the elastic member includes a connecting plate 22 movably arranged in the buffer groove 18, a buffer column 21 fixed on the outer wall of the side of the moving plate 12 close to the spring hole 20, and an abutment plate 19 fixed on the outer wall of the side of the moving plate 12 away from the spring hole 20, one end of the buffer column 21 extends to the spring hole A buffer spring is fixed in 20, and the other end of the buffer spring is fixedly connected to the inner wall of the spring hole 20. One end of the abutment plate 19 extends into the mounting groove 9, and the end of the abutment plate 19 located in the mounting groove 9 is a right-angled triangle mechanism with the inclined surface facing downward. The abutment plate 19 cooperates with the mounting groove 9, and the mold is placed in the placement space. The two clamps 7 are clamped on the outer periphery of the mold to prevent the mold from sliding on the pallet. After the abutment plate 19 loses the extrusion of the side wall of the mounting groove 9, the buffer spring will pop the buffer column 21 outward, thereby driving the connecting plate 22 and the clamp 7 to move to the side away from the center of the pallet 8, thereby increasing the placement space and making it easier for the casting to fall from the pallet.

[0049] The implementation principle of this embodiment is as follows: the support plate 8 will be placed flat in the mounting groove 9 under the action of the return spring. At this time, the two abutment plates will also be squeezed by the inner walls on both sides of the mounting groove 9. At this time, when the mold is placed in the placement space, the outer periphery of the mold will be engaged in the placement space, thereby preventing the mold from moving during the rotation of the placement plate 2. After the support plate 8 is lifted upward, after the abutment plate 19 moves to the outside of the mounting groove 9, the abutment plate 19 will lose the restriction of the mounting groove 9, so that the connecting plate 22 and the clamping plate 7 move to the side away from the center of the support plate 8 under the action of the buffer spring, and the placement space will increase accordingly. The casting on the support plate 8 will also be easier to fall off the support plate 8 due to the inclination of the support plate 8, thereby completing the unloading.

[0050] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
