Description

Technical Field

[0001] This utility model relates to the field of casting demolding technology, and in particular to a rapid casting demolding mechanism. Background Technology

[0002] In modern industrial production, casting, as an important metal forming process, is widely used in many fields such as automobile manufacturing, aerospace, and machinery equipment. With the rapid development of the manufacturing industry, increasingly higher requirements are being placed on the production efficiency, precision, and quality of castings. The demolding process, as a crucial step in the casting process, directly affects the overall production progress and product quality in terms of its efficiency and reliability.

[0003] Currently, some casting molds rely primarily on mechanical ejection devices or manual operation during the demolding process. For some molds with complex structures or large castings, the ejection process may result in significant friction between the workpiece and the mold cavity wall, leading to insufficient demolding smoothness. This increases the likelihood of mold cavity wear and affects production efficiency. Therefore, improving demolding smoothness and reducing friction and wear during the demolding process remains a technical challenge that needs improvement. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a fast casting demolding mechanism, which effectively solves the deficiencies of the prior art.

[0005] To achieve the above objectives, one embodiment of this utility model provides a rapid casting demolding mechanism, including a support base. A mold body is fixedly connected to the top of the support base. A mold cavity is formed at the center of the top surface of the mold body. A push plate receiving groove is formed at the center of the bottom surface of the mold cavity. A through hole is formed at the center of the bottom surface of the push plate receiving groove, communicating with the interior of the support base. A demolding push plate is movably connected inside the push plate receiving groove. The top surface of the demolding push plate is flush with the bottom surface of the mold cavity. Several through holes extending from the outer wall to the push plate are formed at positions corresponding to the center of the push plate receiving groove on the side of the mold body. The mold body has several air vents inside the plate receiving groove. Each of the air vents is fixedly connected to a connecting nozzle at one end of the outer wall of the mold body. A ring-shaped connecting pipe is fixedly connected to the outer side of the connecting nozzles. A high-pressure air pump is fixedly connected to the middle of one side of the outer wall of the mold body. The output end of the high-pressure air pump is fixedly connected to and communicates with the inside of the ring-shaped connecting pipe. Several heat dissipation flat holes are opened on the edge of the top surface of the mold body. The heat dissipation flat holes are respectively connected to the inside of the air vents. A demolding hydraulic rod is provided in the middle of the inner wall of the support base. The telescopic end of the demolding hydraulic rod is fixedly connected to the center of the bottom surface of the demolding push plate.

[0006] Airflow is delivered to the annular connecting pipe and air guide holes at the bottom of the mold cavity by a high-pressure air pump. The heat dissipation area is expanded through heat dissipation flat holes, allowing the workpiece inside the mold cavity to dissipate heat quickly and contract slightly. This creates a gap between the workpiece and the inner wall of the cavity, reducing friction and improving demolding smoothness. The demolding hydraulic lever pushes the demolding ejector plate, causing airflow to flow upwards through the gap between the workpiece and the inner wall of the mold cavity, providing auxiliary lubrication for the workpiece and further improving ejection stability for rapid demolding.

[0007] Preferably, in any of the above solutions, the side of the mold body corresponding to the plurality of air guide holes is a groove structure, the groove structure surrounds the mold body, the plurality of air guide holes are all located inside the groove, and the annular connecting pipe is located inside the groove.

[0008] The technical effect achieved by adopting the above solution is that the groove structure can partially surround the annular connecting pipe, which can play a protective role for the annular connecting pipe.

[0009] Preferably, in any of the above embodiments, guide posts are fixedly connected to the four corners of the bottom surface of the demolding push plate, and the four guide posts penetrate through the bottom surface of the mold body and are slidably connected to the mold body. The length of the four guide posts is greater than the depth of the inner wall of the mold cavity.

[0010] The technical effect achieved by adopting the above solution is that the stability of the demolding ejector plate being pushed upward can be improved by the guidance of the four guide pillars.

[0011] Preferably, in any of the above solutions, the dimensions of the demolding push plate are adapted to the dimensions inside the push plate receiving groove, the extension stroke of the extension end of the demolding hydraulic rod is greater than the depth of the inner wall of the mold cavity, and the top surface dimension of the demolding push plate is smaller than the bottom surface dimension of the mold cavity.

[0012] The technical effect achieved by the above solution is that after the demolding ejector plate lifts the workpiece, a gap is left between the side of the demolding ejector plate and the side of the inner wall of the mold cavity, so that airflow can enter the gap between the edge input workpiece and the inner wall of the mold cavity.

[0013] Preferably, in any of the above embodiments, a plurality of heat dissipation flat holes are arranged around the mold cavity, and the depth of the plurality of heat dissipation flat holes is greater than the depth of the inner wall of the mold cavity.

[0014] The technical effect achieved by adopting the above solution is that the heat dissipation flat hole inner wall surface can uniformly release the heat from the inner wall of the mold cavity, thereby improving the uniformity of heat dissipation and cooling.

[0015] This utility model has the following advantages:

[0016] 1. This rapid casting demolding mechanism first inputs high-pressure airflow into the annular connecting pipe through a high-pressure air pump during demolding. The airflow is then distributed through the annular connecting pipe and output through several air guide holes and several heat dissipation flat holes. These flat holes expand the heat dissipation area and shorten the heat conduction distance with the mold cavity, allowing for rapid heat dissipation of the workpiece inside the mold cavity. This causes the workpiece to shrink to a certain size, leaving a certain gap between it and the inner wall of the mold cavity. This reduces contact friction and wear on the edges of the workpiece during demolding.

[0017] 2. This rapid casting demolding mechanism pushes the demolding push plate upwards via a demolding hydraulic lever, causing the demolding push plate to disengage from the push plate receiving groove. This removes obstruction from the output ends of several air guide holes, allowing airflow to exit from the push plate receiving groove. The airflow then flows upwards through the gap between the workpiece and the inner wall of the mold cavity, thereby improving lubrication and smoothing the ejection process for faster demolding.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0023] like Figures 1 to 3As shown, a rapid casting demolding mechanism includes a support base 1, a mold body 2 fixedly connected to the top of the support base 1, a mold cavity 3 formed at the center of the top surface of the mold body 2, a push plate receiving groove 4 formed at the center of the bottom surface of the mold cavity 3, a through hole formed at the center of the bottom surface of the push plate receiving groove 4 communicating with the interior of the support base 1, a demolding push plate 5 movably connected inside the push plate receiving groove 4, the top surface of the demolding push plate 5 being flush with the bottom surface of the mold cavity 3, and several air guide holes 9 forming from the outer wall to the interior of the push plate receiving groove 4 at positions corresponding to the center of the push plate receiving groove 4 on the side of the mold body 2. A number of air guide holes 9 are fixedly connected to a connecting nozzle 8 at one end of the outer wall of the mold body 2. A ring-shaped connecting pipe 7 is fixedly connected to the outer side of the connecting nozzles 8. A high-pressure air pump 10 is fixedly connected to the middle of one side of the outer wall of the mold body 2. The output end of the high-pressure air pump 10 is fixedly connected to and communicates with the inside of the ring-shaped connecting pipe 7. A number of heat dissipation flat holes 6 are opened on the top edge of the mold body 2. The heat dissipation flat holes 6 are respectively connected to the inside of the air guide holes 9. A demolding hydraulic rod 11 is provided in the middle of the inner wall of the support base 1. The telescopic end of the demolding hydraulic rod 11 is fixedly connected to the center of the bottom surface of the demolding push plate 5.

[0024] As an optional technical solution of this utility model, the side of the mold body 2 and the position corresponding to the several air guide holes 9 are groove structures. The groove structure surrounds the mold body 2, and the several air guide holes 9 are all inside the groove. The annular connecting pipe 7 is inside the groove. The groove structure can partially surround the annular connecting pipe 7, which can play a protective role for the annular connecting pipe 7.

[0025] As an optional technical solution of this utility model, guide posts 12 are fixedly connected to the four corners of the bottom surface of the demolding push plate 5. The four guide posts 12 penetrate through the bottom surface of the mold body 2 and are slidably connected to the mold body 2. The length of the four guide posts 12 is greater than the depth of the inner wall of the mold cavity 3. The stability of the demolding push plate 5 being pushed upward can be improved by the guidance of the four guide posts 12.

[0026] As an optional technical solution of this utility model, the size of the demolding push plate 5 is adapted to the internal size of the push plate receiving groove 4, the extension stroke of the extension end of the demolding hydraulic rod 11 is greater than the depth of the inner wall of the mold cavity 3, and the top surface size of the demolding push plate 5 is smaller than the bottom surface size of the mold cavity 3, so that after the demolding push plate 5 lifts the workpiece, there is a gap between the side of the demolding push plate 5 and the side of the inner wall of the mold cavity 3, so that the airflow can enter the gap between the edge input workpiece and the inner wall of the mold cavity 3.

[0027] As an optional technical solution of this utility model, a plurality of heat dissipation flat holes 6 are arranged around the mold cavity 3, and the depth of the plurality of heat dissipation flat holes 6 is greater than the depth of the inner wall of the mold cavity 3, so that the inner wall surface of the heat dissipation flat holes 6 can uniformly release the heat of the inner wall of the mold cavity 3, thereby improving the uniformity of heat dissipation and cooling.

[0028] The following steps are required when using this rapid casting demolding mechanism:

[0029] 1) First, high-pressure airflow is input into the annular connecting pipe 7 through the high-pressure air pump 10. The airflow is distributed through the annular connecting pipe 7 and output through several air guide holes 9. The airflow is expanded through several heat dissipation flat holes 6 and the heat dissipation area is expanded through several heat dissipation flat holes 6, and the heat conduction distance with the mold cavity 3 is shortened. This can quickly dissipate heat from the workpiece inside the mold cavity 3, causing it to shrink to a certain size and leaving a certain gap with the inner wall of the mold cavity 3.

[0030] 2) The demolding push plate 5 is pushed upward by the demolding hydraulic rod 11, so that the demolding push plate 5 is dislodged from the push plate receiving groove 4, thereby removing the obstruction of the output ends of several air guide holes 9, allowing the airflow to be output from the push plate receiving groove 4, thereby allowing the airflow to be output upward, and allowing the airflow to be output upward through the gap between the workpiece and the inner wall of the mold cavity 3, thereby improving the lubrication effect and improving the smoothness of ejection.

[0031] 3) Then, by continuing to push through the demolding hydraulic lever 11, the workpiece can be pushed out of the mold cavity 3 by the demolding push plate 5, thus completing the demolding.

[0032] In summary, during demolding, high-pressure airflow is first input into the annular connecting pipe 7 via the high-pressure air pump 10. The airflow is distributed through the annular connecting pipe 7 and then output through several air guide holes 9 and several heat dissipation flat holes 6. The heat dissipation flat holes 6 expand the heat dissipation area and shorten the heat conduction distance with the mold cavity 3, which can quickly dissipate heat from the workpiece inside the mold cavity 3, causing it to shrink to a certain size and leaving a certain gap with the inner wall of the mold cavity 3. This reduces contact friction and wear at the edges of the workpiece during demolding. The demolding hydraulic rod 11 pushes the demolding push plate 5 upward, causing it to disengage from the push plate receiving groove 4. This removes the obstruction from the output ends of the several air guide holes 9, allowing the airflow to be output from the push plate receiving groove 4. The airflow is then output upward through the gap between the workpiece and the inner wall of the mold cavity 3, thereby improving the lubrication effect, enhancing the smoothness of ejection, and facilitating rapid demolding.
