Description

Technical Field

[0001] This utility model belongs to the field of riser separation technology for casting components, specifically a separation device for top-pouring risers of casting components. Background Technology

[0002] As is well known, the initial method of separating the riser from the casting was to use a sledgehammer to break the riser. This method, which began in casting, is still in use today. However, this method has the following drawbacks: it is labor-intensive, easily damages the casting, and generates secondary dust and noise from hammering the riser, resulting in significant environmental pollution. Most importantly, it is inefficient, severely restricting the improvement of production capacity. In existing separators, the casting and the separator are not supported during use, and when operated by one person, the separator and the casting are prone to shifting and becoming uncontrollable. This can cause the separator to damage the main body of the casting, and it is also impossible to effectively remove the riser from the casting. Therefore, there is an urgent need to design a separation device for the riser of the casting to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide a separation device for the top injection riser of a casting, which solves the problems mentioned above, such as the many defects in hammering the riser and the lack of support force in existing separators, which makes it impossible to effectively remove the casting due to lack of support.

[0004] To solve the above-mentioned technical problems, this utility model provides a separation device for the top injection riser of a casting. The separation device includes a separator and a first tooling or a second tooling that cooperates with the separator. The casting is placed inside the first tooling and pressed down by the first tooling, or the casting is placed in the second tooling and fixed by fasteners.

[0005] The separator includes a tilting arm, an auxiliary support frame, a hydraulic cylinder, and clamps. The tilting arm is mounted on one side of the clamps via a connecting frame. The auxiliary support frame is rotatably connected to the fixed end of the hydraulic cylinder via a rotating shaft. The clamps are a pair. The hydraulic cylinder controls the pair of clamps to open or close via a hydraulic system to clamp the gating riser of the casting component. The tilting arm is tilted to pry the casting riser of the casting component away.

[0006] Furthermore, the first tooling includes a limiting block, an auxiliary frame, and a blocking block. The auxiliary frame is U-shaped, and there are two limiting blocks, which are respectively disposed at the bottom of the open end of the auxiliary frame. The blocking block is disposed at the top of the closed end of the auxiliary frame. The pouring riser of the casting component passes through the auxiliary frame, and one side of the first main body below the pouring riser of the casting component abuts against the two limiting blocks. The bottom of the auxiliary frame presses against the top of the first main body.

[0007] Furthermore, the limiting block, auxiliary frame, and blocking block are integrally formed structures.

[0008] Furthermore, the second tooling includes a base plate and a first stop and a second stop disposed on both sides of the base plate. The height of the first stop is lower than the height of the second stop. The casting component is disposed on the base plate and located between the first stop and the second stop. The height of the casting riser of the casting component at the junction with the first body is flush with the height of the first stop.

[0009] Furthermore, the base plate, the first stop, and the second stop are integrally formed.

[0010] Furthermore, if the weight of the casting part is ≥5Kg, the first tooling is selected; if the weight of the casting part is ≤5Kg, the second tooling is selected.

[0011] Furthermore, a tilting drag frame is provided on the outside of the hydraulic cylinder, and a first handle is fixedly installed on the tilting drag frame.

[0012] Furthermore, the tilting arm is provided with a second handle.

[0013] Furthermore, a pin is provided through the side wall of the auxiliary support frame, and the lower part of the pin can extend out or retract into the bottom of the auxiliary support frame.

[0014] The beneficial effects of this utility model are as follows: The separation device of this utility model uses a separator in conjunction with the first tooling or the second tooling to separate the pouring riser of the casting, which effectively solves the defects of high labor intensity, easy damage to castings, secondary dust, noise, environmental pollution, low efficiency and serious restriction on production capacity caused by hammering the riser.

[0015] The separator is designed with auxiliary support to stabilize the hydraulic cylinder and the clamp connected to the hydraulic cylinder when adjusting the hydraulic cylinder. This is to avoid the problem that the separator may tilt as a whole and damage the casting parts when the hydraulic cylinder and clamp on the tilting frame are rotated by pulling the first handle without support.

[0016] After the support force of the auxiliary support frame is unlocked, the entire separator can be vertically flipped by the flipping arm to remove the pouring riser of the casting part, thereby increasing the removal rate of the pouring riser.

[0017] The first tooling is set up by using a U-shaped auxiliary frame to surround the pouring riser of the casting part, and the bottom of the auxiliary frame presses down on the first main body below the pouring riser, so as to effectively fix the casting part and improve the stability and efficiency of the casting part being pulled away from the pouring riser.

[0018] The second tooling is designed to intercept the casting component on the base plate using the first and second stops, and to fit the casting component against the first stop. It is then fixed with fasteners. The height of the connection between the casting riser and the first body is flush with the height of the first stop, which effectively facilitates the removal of the casting riser and avoids the risk of it being unable to be removed due to the obstruction of the first stop.

[0019] The pins on the side wall of the auxiliary support frame allow for the fixing and separation of the auxiliary support frame from the fixed object by inserting and removing the pins. After fixing the auxiliary support frame, the hydraulic cylinder can be pulled up and down to adjust the tilt angle of the clamp, so that the clamp is positioned at the junction of the casting riser and the first main body, facilitating the removal of the casting riser and providing good support for the separator. The separator can be adjusted to the required position simply by pulling the first handle, effectively reducing the labor intensity of manual labor and preventing the separator from being too heavy for one person to handle and injuring the first main body. After adjusting the position, the pins can be pulled out to release the auxiliary support frame, and the casting riser of the casting machine can be removed by flipping the tilting arm.

Detailed Implementation

[0028] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] The following will describe a specific embodiment of this utility model and its appendix. Figure 1-6 To explain in detail, a separation device for a top-fill riser of a casting is disclosed. The separation device 1 includes a separator 11 and a first tooling 12 or a second tooling 13 that cooperates with the separator 11. The casting 2 is placed inside the first tooling 12 and pressed down by the first tooling 12, or the casting 2 is placed in the second tooling 13 and fixed by fasteners.

[0030] The separator 11 includes a tilting arm 111, an auxiliary support frame 112, a hydraulic cylinder 113, and clamps 114. The tilting arm 111 is equipped with a second handle 1111. The tilting arm 111 is mounted on one side of the clamps 114 via a connecting frame 118. The auxiliary support frame 112 is rotatably connected to the fixed end of the hydraulic cylinder 113 via a rotating shaft 119. A tilting drag frame 115 is located outside the hydraulic cylinder 113, and a first handle 116 is fixedly mounted on the tilting drag frame 115. The clamps 114 are a pair, and the pair of clamps 114 are connected by a steering mechanism. Connected to the output end of the hydraulic cylinder 113, the steering mechanism includes a second rotating shaft, which is located at the intersection of a pair of clamps 114. The ends of the pair of clamps 114 are connected to the piston rod of the hydraulic cylinder 113 via a steering connecting frame. The steering connecting frame is used to convert the lateral hydraulic pressure of the piston rod into a force that causes the pair of clamps 114 to open or close. The hydraulic cylinder 113 controls the pair of clamps 114 to open or close via a hydraulic system to clamp the gating riser 21 of the casting part 2. The flipping arm 111 is then flipped to disengage the gating riser 21 of the casting part 2.

[0031] In this embodiment, the cross-sectional area of ​​the auxiliary support frame 112 and the hydraulic cylinder 113 in cooperation is larger than the cross-sectional area of ​​the neck of the pouring riser 21, so as to avoid the auxiliary support frame 112 from breaking.

[0032] The separation device 1 of this utility model uses the separation device 11 in conjunction with the first tooling 12 or the second tooling 13 to separate the pouring riser 21 of the casting part 2, so as to effectively solve the defects of high labor intensity, easy damage to castings, secondary dust, noise, environmental pollution, low efficiency and serious restriction on production capacity caused by hammering the riser.

[0033] The separator 11 is set up with auxiliary support to stabilize the support force when adjusting the hydraulic cylinder 113 and the clamp 114 connected to the hydraulic cylinder 113, so as to avoid the problem that the separator 11 is easy to tilt as a whole and damage the casting part 2 when the hydraulic cylinder 113 and clamp 114 on the flipping drag frame 115 are rotated by pulling the first handle 116.

[0034] After the support force of the auxiliary support frame 112 is unlocked, the entire separator 11 can be vertically flipped by the flipping arm 111 to remove the pouring riser 21 of the casting part 2, thereby increasing the removal rate of the pouring riser 21.

[0035] The first tooling 12 includes a limiting block 121, an auxiliary frame 122, and a blocking block 123. The limiting block 121, the auxiliary frame 122, and the blocking block 123 are integrally formed. The auxiliary frame 122 is U-shaped. There are two limiting blocks 121, which are respectively set at the bottom of the open end of the auxiliary frame 122. The blocking block 123 is set at the top of the closed end of the auxiliary frame 122. The pouring riser 21 of the casting part 2 passes through the auxiliary frame 122, and one side of the first main body 22 below the pouring riser 21 of the casting part 2 abuts against the two limiting blocks 121. The bottom of the auxiliary frame 122 is pressed against the top of the first main body 22.

[0036] The first tooling 12 is set up so that the pouring riser 21 of the casting part 2 is surrounded by the U-shaped auxiliary frame 122, and the bottom of the auxiliary frame 122 presses down on the first main body 22 below the pouring riser 21, so as to effectively fix the casting part 2 and improve the stability and efficiency of the casting part 2 being pulled away from the pouring riser 21.

[0037] The second tooling 13 includes a base plate 131 and a first stop 132 and a second stop 133 disposed on both sides of the base plate 131. The height of the first stop 132 is lower than the height of the second stop 133. The casting part 2 is disposed on the base plate 131 and is located between the first stop 132 and the second stop 133. The height of the casting riser 21 of the casting part 2 at the junction with the first body 22 is flush with the height of the first stop 132.

[0038] The second tooling 13 is set up so that the casting part 2 is intercepted on the base plate 131 by the first stop 132 and the second stop 133, and the casting part 2 is attached to the first stop 132 and then fixed by fasteners. The height of the connection between the casting riser 21 and the first body 22 is flush with the height of the first stop 132, so that the casting riser 21 can be effectively removed without the risk of being unable to be removed due to the obstruction of the first stop 132.

[0039] The base plate 131, the first stop 132, and the second stop 133 are integrally formed.

[0040] If the weight of casting part 2 is ≥5Kg, the first tooling 12 shall be selected; if the weight of casting part 2 is ≤5Kg, the second tooling 13 shall be selected.

[0041] A pin 117 is provided through the side wall of the auxiliary support frame 112. The lower part of the pin 117 can extend or retract to the bottom of the auxiliary support frame 112. The pin 117 on the side wall of the auxiliary support frame 112 can be used to fix and separate the auxiliary support frame 112 from the fixed object by inserting and removing the pin 117. After the auxiliary support frame 112 is fixed, the tilt angle of the clamp 114 can be adjusted by pulling the hydraulic cylinder 113 to rotate up and down, so that the clamp 114 can be positioned between the casting riser 21 and the first... The connection point of the main body 22 is designed to facilitate the removal of the pouring riser 21, providing good support for the separator 11. The separator 11 can be adjusted to the required position simply by pulling the first handle 116, effectively reducing the labor intensity of manual labor. At the same time, it can also effectively avoid the risk of the separator 11 being too heavy for one person to handle and injuring the first main body 22. After the position is adjusted, the auxiliary support frame 112 can be fixed by pulling out the pin 117, and the pouring riser 21 of the pouring part 2 can be removed by flipping the flipping arm 111.

[0042] The working process of this utility model is as follows:

[0043] The choice between using the first tooling 12 or the second tooling 13 depends on the weight of the casting 2.

[0044] If the first tooling 12 is selected, first determine the support position of the auxiliary support frame 112 of the separator 11. Place the first tooling 12 on one side of the support position. Then, pass the inner cavity of the U-shaped auxiliary frame 122 of the first tooling 12 through the casting riser 21 of the casting part 2 with a weight ≥5Kg, and press the bottom of the auxiliary frame 122 onto the first body 22 of the casting part 2. Move the first tooling 12 so that the inner sides of its two limiting blocks 121 are flush with the side wall of the first body 22 of the casting part 2. Insert the pin 117 of the auxiliary support frame 112 of the separator 11 into the fixed seat of the support position, and pull the separator 11. The first handle 116 pulls the hydraulic cylinder 113 and clamp 114 on the tilting drag frame 115 to rotate with the rotating shaft 119 to adjust the height of the end of the clamp 114. At the same time, the hydraulic system is activated to control the pair of clamps 114 to open so that the jaws of the clamps 114 are located on both sides of the casting riser 21. The hydraulic system is controlled to clamp the casting riser 21. After clamping the casting riser 21, the first handle 116 is released, the pin 117 of the auxiliary support frame 112 of the separator 11 is pulled away from the fixed seat, the second handle 1111 is grasped, and the tilting arm 111 is driven to tilt to pull the casting riser 21 away from the first body 22.

[0045] If the second tooling 13 is selected, first determine the support position of the auxiliary support frame 112 of the separator 11. Place the second tooling 13 on one side of the support position. Place the casting part 2 with a weight ≤5Kg on the base plate 131, between the first stop frame 132 and the second stop frame 133. Press the side wall of the first main body 22 of the casting part 2 against the first stop frame 132. Use fasteners, namely long screws and pressure plates. Screw the long screws onto the base plate and press the pressure plate onto the first main body 22. Lock it with a lock nut. Insert the pin 117 of the auxiliary support frame 112 of the separator 11 into the fixed seat at the support position and pull the separator. The first handle 116 on the separator 11 pulls the hydraulic cylinder 113 and clamp 114 on the tilting frame 115 to rotate with the shaft 119 to adjust the height of the end of the clamp 114. At the same time, the hydraulic system is activated to control the pair of clamps 114 to open so that the jaws of the clamps 114 are located on both sides of the casting riser 21. The hydraulic system is controlled to clamp the casting riser 21. After clamping the casting riser 21, the first handle 116 is released, the pin 117 of the auxiliary support frame 112 of the separator 11 is pulled away from the fixed seat, the second handle 1111 is grasped, and the tilting arm 111 is driven to tilt, so as to pull the casting riser 21 away from the first body 22.

[0046] The separator 11 of this application stabilizes the casting part 2 by cooperating with the first tooling 12 or the second tooling 13, so that the separator 11 can separate the casting risers 21 of casting parts 2 of different weights.

[0047] The above-disclosed embodiment is merely a preferred embodiment of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
