Description

Technical Field

[0001] The utility model relates to the technical field of die casting moulds, in particular to a steel ball die casting mould. Background Art

[0002] The steel ball die casting mold is a special tool used to make steel balls. During the die casting process, molten metal is injected into the mold cavity at high pressure and forms the desired steel ball shape after cooling.

[0003] Existing steel ball die-casting molds usually use a push rod to eject the steel ball for unloading. However, this method may cause damage to the steel ball surface. During the ejection process, the push rod is in direct contact with the steel ball. If the push rod is improperly designed or operated inaccurately, it is easy to leave scratches or indentations on the steel ball surface, affecting the appearance quality of the product. At the same time, the push rod unloading method may also cause increased mold wear. Frequent ejection actions cause the contact surface between the push rod and the mold to constantly rub, which aggravates the wear of the mold and shortens the service life of the mold. Therefore, we propose a steel ball die-casting mold. Utility Model Content

[0004] The purpose of the utility model is to provide a steel ball die-casting mold to solve the problem that the existing steel ball die-casting mold proposed in the above background technology usually adopts a push rod to eject the steel ball for unloading. However, this method may cause damage to the surface of the steel ball. During the ejection process, the push rod is in direct contact with the steel ball. If the push rod is improperly designed or operated inaccurately, it is easy to leave scratches or indentations on the surface of the steel ball, affecting the appearance quality of the product. At the same time, the push rod unloading method may also cause increased wear of the mold. Frequent ejection actions cause continuous friction between the contact surface between the push rod and the mold, which aggravates the wear of the mold and shortens the service life of the mold.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a steel ball die-casting mold, comprising a mounting frame, a shell is arranged at the center of the mounting frame, a bottom plate is fixedly installed at the bottom of the mounting frame, a spring is fixedly installed at the top of the shell, the front end and the rear end of the top on both sides of the shell are fixedly connected with guide blocks, guide rods are fixedly installed at the four corners of the top of the mounting frame, a first motor is fixedly installed at the bottom of one side of the mounting frame, a long rod is arranged at the bottom position of the mounting frame, cams are fixedly installed at the two side positions of the surface of the long rod, the upper ends of the two cams are in contact with the bottom of the shell, a second motor is fixedly installed at the center position of one side of the shell, a lower mold is arranged at the center position of the shell, the centers of both sides of the lower mold are fixedly connected with shaft rods, electric push rods are fixedly installed at the two side positions of the top of the shell, an upper mold is fixedly installed at the lower ends of the two electric push rods, and a material receiving box is fixedly installed at the inner bottom of the shell.

[0006] Compared with the prior art, the beneficial effects of the utility model are:

[0007] The steel ball die-casting mold is designed with a spring, a guide block, a guide rod, a first motor, a long rod, a cam, a second motor, a material receiving box and a buffer pad. The lower mold can be flipped by the drive of the second motor. This design effectively changes the traditional unloading method and avoids the surface damage problem caused by the steel ball being directly ejected by the ejector rod. At the same time, after starting the first motor, the cam rotates accordingly, and the elasticity of the spring is used to make the shell body shake up and down under the action of the cam. This shaking can further promote the shaking of the lower mold, so that the steel ball can fall off the mold smoothly, realizing an efficient and safe unloading process. In addition, the unloading method of the mold design not only improves production efficiency, but also significantly reduces operation difficulty and labor costs. Since no manual intervention is required during the unloading process, the risk of safety accidents caused by operational errors is greatly reduced. At the same time, the setting of the material receiving box enables the unloaded steel balls to be collected in a centralized manner, which is convenient for subsequent sorting and processing, further improving the overall production efficiency.

[0015] There are four springs 3 , and the upper ends of the four springs 3 are fixedly connected to the inner top of the mounting frame 1 . Under the action of the springs 3 , the bottom of the housing 2 can always be in contact with the outer edge of the cam 9 .

[0016] The lower ends of the four guide rods 5 respectively penetrate the outside of the four guide blocks 4, and the lower ends of the guide rods 5 are fixedly connected to the limit blocks 6. The bottoms of the guide blocks 4 are in contact with the tops of the limit blocks 6, which play a guiding and limiting role on the shell 2.

[0017] The first motor 7 is fixedly connected to the first main shaft through the output end on one side thereof, one end of the first main shaft passes through the mounting frame 1 and is fixedly connected to one end of the long rod 8, and the other end of the long rod 8 is movably connected to a bearing fixedly installed at the bottom position on one side of the mounting frame 1. By controlling the first motor 7, the long rod 8 can drive the cam 9 to rotate.

[0018] The second motor 10 is fixedly connected to the second main shaft through the output end on one side thereof, one side of the second main shaft passes through the shell 2 and is fixedly connected to one end of the right shaft rod 12, one end of the left shaft rod 12 is movably connected to a bearing fixedly installed at a center position on one side of the inner wall of the shell 2, and starting the second motor 10 can drive the lower mold 11 to flip.

[0019] Sliding grooves 16 are provided at the top positions on both sides of the shell 2, and sliding plates 15 are fixedly connected to the tops of both sides of the upper mold 14. The opposite sides of the two sliding plates 15 extend to the inside of the two sliding grooves 16 respectively and are slidably connected to the inner walls of the sliding grooves 16, which has a stabilizing effect on the upper mold 14 when it moves up and down.

[0020] The inner wall of the receiving box 17 is bonded with a buffer pad 18 by an adhesive to provide buffer protection for the steel balls that fall into it.

[0021] Working principle: First, by controlling the extension and retraction of the electric push rod 13, the upper mold 14 moves downward and cooperates closely with the lower mold 11 to inject the molten metal into the mold cavity to complete the die-casting process. After the die-casting process is completed, the second motor 10 is started. The second motor 10 drives the second spindle to rotate through its output end, thereby driving the shaft 12 on both sides of the lower mold 11 to rotate, so as to realize the flipping of the lower mold 11, and then prepare for the next round of unloading. The first motor 7 is started, and the first motor 7 drives the first spindle to rotate, thereby driving the long rod 8 to rotate, and the cam 9 on the surface of the long rod 8 rotates accordingly. Since the upper end of the cam 9 contacts the bottom of the shell 2, the rotation of the cam 9 will push the shell 2 to shake up and down. During the shaking process, due to the presence of the spring 3, the shell 2 can maintain close contact with the cam 9 and effectively absorb the impact to ensure the stability and continuity of the shaking. Under the shaking action of the shell 2, the lower mold 11 also shakes, further promoting the falling of the steel balls. The fallen steel balls fall into the receiving box 17 under the action of gravity. The buffer pad 18 on the inner wall of the receiving box 17 plays a buffering and protective role to prevent the steel balls from being damaged by impact when falling. The entire unloading process does not require manual intervention, realizes automated operation, and improves production efficiency. At the same time, through the cooperation of the guide rod 5 and the guide block 4, the shaking of the shell 2 is guided and limited, ensuring the accuracy and stability of unloading.

[0022] In summary: the steel ball die-casting mold, through the design of the spring 3, guide block 4, guide rod 5, first motor 7, long rod 8, cam 9, second motor 10, material receiving box 17 and buffer pad 18, the lower mold 11 can be turned over by the drive of the second motor 10. This design effectively changes the traditional unloading method and avoids the surface damage problem caused by the steel ball being directly ejected by the ejector rod. At the same time, after starting the first motor 7, the cam 9 rotates accordingly. The elasticity of the spring 3 is used to make the shell 2 shake up and down under the action of the cam 9. This shaking can further promote the shaking of the lower mold 11, so that the steel ball can fall off the mold smoothly, realizing an efficient and safe unloading process. In addition, the unloading method of the mold design not only improves the production efficiency, but also significantly reduces the operation difficulty and labor cost. Since no manual intervention is required during the unloading process, the risk of safety accidents caused by operational errors is greatly reduced. At the same time, the setting of the material receiving box 17 enables the unloaded steel balls to be collected in a centralized manner, which is convenient for subsequent sorting and processing, further improving the overall production efficiency.
