Description

Technical Field

[0001] The present application relates to the technical field of casting molds, and in particular to a casting mold with good stability. Background Art

[0002] A casting mold is a material that is made of other easily formed materials in advance in order to obtain the structural shape of a part. The mold is then placed in a sand mold, forming a cavity with the same size as the part structure. A flowing liquid is then poured into the cavity, and after the liquid cools and solidifies, a part with the same shape and structure as the mold can be formed.

[0003] The casting mold is an important part of the casting process. For example, in the relevant technology, a Chinese patent with publication number CN209491308U proposes a brake disc casting mold, which has the advantages that when the brake disc casting is ejected after the mold is opened, the ejection force acts on the partition and the brake disc casting at the same time, and the force is evenly distributed, which is conducive to ejection and reduces the probability of product damage.

[0004] With regard to the above-mentioned related technologies, the inventors believe that the following defects exist: the design has the disadvantage of poor stability, which causes the casting mold to easily shake or shift during the casting process of the parts. The staff needs to use tools to limit and fix the casting mold, and after the parts are cast, the casting mold needs to be opened with the help of tools. This method is not only time-consuming and labor-intensive, but also increases the labor intensity of the staff. It is inconvenient to use and reduces the efficiency and effect of the casting mold. Utility Model Content

[0005] In order to solve the problem that the existing casting mold has a shortcoming of poor stability, which causes the casting mold to shake or shift easily during the casting process of parts, and the staff needs to use tools to limit and fix the casting mold, and after the casting of the parts is completed, the casting mold needs to be opened with the help of tools. The present application provides a casting mold with good stability.

[0006] The present application provides a casting mold with good stability, which adopts the following technical solution:

[0007] A casting mold with good stability comprises a casting base, a demoulding mechanism and a positioning mechanism, wherein the top of the casting base is fixedly connected to a mold body, and the top of the mold body is movably connected to a mold pressing block;

[0008] The demoulding mechanism comprises a driving box, the right side of the driving box is fixedly connected to a motor, the output shaft of the motor is fixedly connected to a movable screw, the outer side of the movable screw is threadedly connected to two movable screw blocks, the bottoms of the two movable screw blocks are fixedly connected to movable sliders, the bottoms of the two movable sliders are fixedly connected to a first hinge block, the inner sides of the two first hinge blocks are hinged with adjustment rods, the ends of the two adjustment rods away from the first hinge blocks are hinged with second hinge blocks, the outer sides of the two second hinge blocks are fixedly connected to movable hooks, the top of the mold pressing block is fixedly connected to two fixed hanging rings, and the two fixed hanging rings are movably connected to the two movable hooks respectively;

[0009] The positioning mechanism includes fixed blocks fixed on the left and right sides of the mold body, the inner sides of the two fixed blocks are fixedly connected with fixed screw blocks, the inner sides of the two fixed screw blocks are threadedly connected with threaded rods, the outer sides of the two threaded rods are fixedly connected with movable turning handles, the outer sides of the two threaded rods are fixedly connected with rolling bearings, and the outer sides of the two rolling bearings are fixedly connected with movable clamping blocks.

[0010] By adopting the above technical scheme, the mold body and the mold block can be used to cast parts. When the mold block needs to be lifted, it is only necessary to hook the two fixed hanging rings with two movable hooks, and drive the movable screw to rotate through the motor, thereby driving the two movable screw blocks, the two movable sliders and the two first hinge blocks to move away from each other, so that the two movable hooks, the two fixed hanging rings and the mold block are driven to move upward through the connection and cooperation between the two first hinge blocks, the two adjusting rods and the two adjusting rods, so as to realize the lifting of the mold block separated from the mold body.

[0011] At the same time, when the mold body and the mold block are casting the parts, the technicians only need to rotate the two movable handles to drive the two threaded rods to rotate respectively, and then drive the two rolling bearings and the two movable clamps to move relative to each other, and move the two movable clamps to the inside of the mold body to achieve the installation and positioning of the mold body and the mold block, avoiding the mold block from shifting during the casting of the inner material of the mold body, so as to ensure the processing effect of the mold block and the mold body on the parts.

[0012] Optionally, a positioning block is fixedly connected to the bottom of the mold pressing block, a positioning square groove is provided on the top of the mold body, two positioning blocks are respectively located on the inner sides of two positioning square grooves, positioning slots are provided on the inner sides of the two positioning blocks, and two movable clamps are respectively engaged with the two positioning slots.

[0013] By adopting the above technical solution, by setting two positioning blocks and two positioning square grooves, the mold block can be installed and positioned, so as to avoid the mold block from shifting during the process of sealing the mold body, and the time for the staff to align and measure the mold block and the mold body can be saved. At the same time, positioning slots are respectively opened on the inner sides of the two positioning blocks, and two movable clamps are used to ensure the stability of the installation and positioning of the mold block and the two positioning blocks and the mold body.

[0014] Optionally, the tops of the two movable clamps are fixedly connected with support slides, the inner sides of the two fixed blocks are provided with support grooves, the two support slides are respectively slidably connected to the two support grooves, and the two support slides and the two support grooves are both T-shaped.

[0015] By adopting the above technical solution, the left and right movement of the movable clamp is supported by a rolling bearing. In this way, the left and right movement of the movable clamp is not smooth and is prone to rotation during the movement. Therefore, by setting two supporting sliders and two supporting grooves, the two movable clamps can be supported and the stability of the left and right movement of the movable clamp can be ensured.

[0016] Optionally, a support bearing is fixedly connected to the outer side of the movable screw rod, and the support bearing is fixedly connected to the drive box. The left end of the movable screw rod passes through the drive box, the movable screw block and the support bearing in sequence and extends to the inner side of the support bearing.

[0017] By adopting the above technical scheme, the movable screw is not stable when it is supported only by the motor during rotation. Because by setting a support bearing, the movable screw can be supported and the motor can be cooperated to make the movable screw rotate stably. The support bearing is composed of four parts: an inner ring, an outer ring, a circular moving body and a partition frame. The function of the inner ring is to cooperate with the movable screw and rotate with the movable screw, and the function of the outer ring is to cooperate with the drive box to play a supporting role.

[0018] Optionally, a telescopic rod is fixedly connected to the bottom of the drive box, and the telescopic rod is fixedly connected to the mold block. The telescopic rod consists of an inner rod and an outer rod, and the inner rod is a solid rod and the outer rod is a hollow rod. The first hinge block is movably connected to the adjusting rod through a movable pin, and the second hinge block is movably connected to the adjusting rod through a connecting pin.

[0019] By adopting the above technical solution, the upward movement of the mold pressing block is supported only by the two first hinge blocks, the two adjusting rods and the two second hinge blocks, which is prone to left and right shaking and deviation, making the up and down movement of the mold pressing block unstable. Therefore, by setting a telescopic rod, the mold pressing block can be limited, so that the two first hinge blocks, the two adjusting rods and the two second hinge blocks can drive the mold pressing block to move up and down in a balanced manner.

[0020] Optionally, a fixed long hole is provided at the bottom of the drive box, and the number of the fixed long holes is two, the two movable sliding blocks are respectively slidably connected to the two fixed long holes, and the inner sides of the two movable screw blocks are provided with threaded holes that are compatible with the outer threads of the movable screw rods, and the inner threads of the two threaded holes are in opposite directions.

[0021] By adopting the above technical solution, in the process where the movable screw drives the two movable screw blocks to move left and right, a limiting mechanism must be set to prevent the movable screw from driving the two movable screw blocks to rotate and move left and right. Therefore, by setting two movable sliding blocks and two fixed long holes, the two movable screw blocks can be limited, so that the two movable screw blocks can move left and right in a balanced manner. Threaded holes with opposite thread directions are set on the inner sides of the two movable screw blocks to prevent the two movable screw blocks from moving left or right at the same time, so that the two movable screw blocks can move relative to and away from each other.

[0022] Optionally, a fixed column is fixedly connected to the top of the casting base, a fixed top plate is fixedly connected to the top of the fixed column, a bottom of the fixed top plate is fixedly connected to the drive box, and the number of the fixed columns is four.

[0023] By adopting the above technical solution, the mold body can be supported by the casting base, and the support effect of the fixed top plate can be guaranteed by setting four fixing columns, so that the fixed top plate can support and fix the drive box above the mold block.

[0024] Optionally, the inner sides of the two fixing screw blocks are respectively provided with spiral holes adapted to the outer threads of the two threaded rods, and the end of the threaded rod away from the movable handle sequentially penetrates the fixing block, the fixing screw block and the rolling bearing and extends to the inner side of the rolling bearing.

[0025] By adopting the above technical solution, the rolling bearing can be set to limit the circular rotation of the movable clamp block, thereby preventing the movable clamp block from rotating and moving left and right during the rotation of the threaded rod. At the same time, the rolling bearing can ensure the stability of the rotation of the threaded rod, and the fixed screw block and the threaded rod can be hidden and stored through the fixed block.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. Hook the two fixed hanging rings respectively through the two movable hooks, and then the motor can drive the movable screw to rotate clockwise, thereby driving the two movable screw blocks, the two movable sliders and the two first hinge blocks to move in opposite directions. Because the first hinge block is movably connected to the adjusting rod through the movable pin, and the second hinge block is movably connected to the adjusting rod through the connecting pin, the two movable hooks, the two fixed hanging rings and the mold pressing block can be balancedly driven to move upward through the connection and cooperation between the two first hinge blocks, the two adjusting rods and the two adjusting rods, so that the mold pressing block is separated from the mold body, so that the cast material inside the mold body can be removed. The material is taken out, and at the same time, through the above principle, the motor drives the movable screw to rotate counterclockwise, which can drive the two movable screw blocks, the two movable sliders and the two first hinge blocks to move relatively, and through the connection and cooperation between the two first hinge blocks, the two adjusting rods and the two adjusting rods, the two movable hooks, the two fixed hanging rings and the mold pressing block can be driven downward in a balanced manner, so that the mold pressing block can be fitted with the mold body, so that the material inside the mold body can be cast, thereby achieving the purpose of good stability of the casting mold. After the casting of the parts is completed, there is no need to use tools to open the casting mold, which saves time and effort.

[0028] 2. When it is necessary to cast the material inside the mold body, firstly, according to the above principle, fit the mold block and the mold body together, insert the two positioning blocks into the inner sides of the two positioning square grooves respectively, and then rotate the two movable handles clockwise to drive the two threaded rods to rotate clockwise respectively, thereby driving the two rolling bearings and the two movable clamps to move relative to each other, and the two movable clamps can be moved to the inner sides of the two positioning slots inside the two positioning blocks respectively, so that the two positioning blocks and the mold block can be installed and positioned. At the same time, when it is necessary to remove the cast material inside the mold body, When ejecting, the two threaded rods can be driven to rotate counterclockwise by rotating the two movable handles counterclockwise, and the two rolling bearings and the two movable clamping blocks can be driven to move opposite to each other, so that the two movable clamping blocks are separated from the two positioning blocks respectively, and the two positioning blocks and the mold pressing block lose their limits, so that the mold pressing block can be lifted away from the top of the mold body, ensuring the discharge of the material inside the mold body, achieving the purpose of good stability of the casting mold, avoiding the casting mold from shaking or deflecting during the casting process of the parts, and no staff needs to use tools to limit and fix the casting mold.

[0046] The implementation principle of a casting mold with good stability in the embodiment of the present application is:

[0047] When it is necessary to take out the cast material inside the mold body 13, first hook the two fixed hanging rings 15 respectively through the two movable hooks 12, and then the movable screw 6 can be driven to rotate clockwise by the motor 5. Because the two movable screw blocks 7 are threadedly connected to the movable screw 6, the two movable screw blocks 7, the two movable sliding blocks 8 and the two first hinge blocks 9 will be driven to move away from each other during the clockwise rotation of the movable screw 6. Because the first hinge block 9 is movably connected to the adjusting rod 10 through a movable pin, and the second hinge block 11 is movably connected to the adjusting rod 10 through a connecting pin, the two first hinge blocks 9 will be driven to move away from each other during the process of moving the two first hinge blocks 9, through the connection and cooperation between the two first hinge blocks 9, the two adjusting rods 10 and the two adjusting rods 10, the two movable hooks 12, the two fixed hanging rings 15 and the mold pressing block 14 will be driven to move upward in a balanced manner, so that the mold pressing block 14 is separated from the mold body 13, so that the cast material inside the mold body 13 can be taken out.

[0048] According to the above principle, when it is necessary to use the mold body 13 to die-cast the material inside the mold block 14, the movable screw 6 is driven by the motor 5 to rotate counterclockwise, which can drive the two movable screw blocks 7, the two movable sliders 8 and the two first hinge blocks 9 to move relative to each other. Through the connection and cooperation between the two first hinge blocks 9, the two adjusting rods 10 and the two adjusting rods 10, the two movable hooks 12, the two fixed hanging rings 15 and the mold block 14 can be driven to move downward in a balanced manner, so that the mold block 14 can be fitted with the mold body 13, so that the material inside the mold body 13 can be cast.

[0049] When it is necessary to cast the material on the inner side of the mold body 13, the mold pressing block 14 is first fitted together with the mold body 13 according to the above principle, and the two positioning blocks 22 are respectively inserted into the inner sides of the two positioning square grooves, and then the two movable handles 19 are rotated clockwise to drive the two threaded rods 18 to rotate clockwise respectively. Because the two fixed screw blocks 17 are respectively threadedly connected to the two threaded rods 18, the two threaded rods 18 will respectively drive the two rolling bearings 20 and the two movable clamping blocks 21 to move relative to each other during the rotation. During the relative movement of the two movable clamping blocks 21, they will respectively move to the inner sides of the two positioning grooves on the inner sides of the two positioning blocks 22, so that the two positioning blocks 22 and the mold pressing block 14 can be installed and positioned, so as to avoid the mold pressing block 14 from being offset during the casting of the material on the inner side of the mold body 13, and ensure the casting effect of the mold pressing block 14 on the material on the inner side of the mold body 13.

[0050] At the same time, when it is necessary to take out the cast material inside the mold body 13, the two threaded rods 18 can be driven to rotate counterclockwise by rotating the two movable handles 19 counterclockwise, and the two rolling bearings 20 and the two movable clamping blocks 21 can be driven to move away from each other, so that the two movable clamping blocks 21 are separated from the two positioning blocks 22 respectively, so that the two positioning blocks 22 and the mold pressing block 14 lose their limit, so that the mold pressing block 14 can be lifted away from the top of the mold body 13, ensuring the effect of discharging the material inside the mold body 13.

[0051] Compared with the prior art, the overall structure is simple and easy to use, and the purpose of good stability of the casting mold is achieved, and the casting mold is prevented from shaking or shifting during the casting process of parts. The staff does not need to use tools to limit and fix the casting mold. After the parts are cast, there is no need to use tools to open the casting mold, which saves time and effort, reduces the labor intensity of the staff, and improves the use efficiency and effect of the casting mold.

[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
