Description

Technical Field

[0001] The utility model relates to the technical field of reset mechanisms, and particularly relates to a two-way automatic reset ejection mechanism for a casting mold. Background Technique

[0002] The ejection mechanism of a casting mold is a device used for ejecting a casting mold. The ejection mechanism of the mold is an important part of the mold structure, which is used to eject the molded plastic part or casting from the mold cavity to facilitate smooth demolding. Its working principle is that after the mold is opened, through the action of the ejection mechanism, the plastic part or casting is pushed out from the core or cavity of the mold. Common ejection methods include mechanical ejection, hydraulic ejection, and pneumatic ejection, etc. Mechanical ejection is the most widely used method, which directly acts on the plastic part or casting through mechanical components such as ejector rods and ejector pipes to achieve ejection. Hydraulic ejection and pneumatic ejection respectively use the hydraulic system and the pneumatic system to provide power to complete the ejection action.

[0003] Currently, during the casting production process, the ejection mechanism of the mold is a key component to ensure the smooth demolding of the casting. The traditional ejection mechanism is that the knockout rod of the casting machine descends to eject the top plate, and after the part is taken out, the upper and lower mold reset rods collide during mold closing to push the top plate back to its original position. In gravity casting where a sand core needs to be placed, the mold must be closed for the first time to completely reset the ejector rod and then opened before the sand core can be placed in the cavity. Moreover, it is easy to cause the mold temperature to decrease due to the long standby time, increasing the probability of product defects and thus reducing the working efficiency of mold casting.

[0004] Therefore, we propose a two-way automatic reset ejection mechanism for a casting mold to solve the problems mentioned above. Content of the Utility Model

[0032] In this embodiment, during the casting production process, when it is necessary to take out the casting from the mold, the first cylinder 308 is started to extend, driving the first pressing plate 309 to move upward, and then moving into the interior of the first card slot 310. Among them, the first card slot 310 plays a role in limiting the first pressing plate 309, making it more stable during the up and down movement. The first pressing plate 309 continues to move upward under the drive of the first cylinder 308, thereby driving the first sliding plate 304 to move upward. Among them, multiple first limiting rods 303 play a role in limiting the first sliding plate 304. The movement of the first sliding plate 304 causes the four first springs 312 to be compressed. The upward movement of the first sliding plate 304 drives multiple lower ejector rods 305 to move upward, thereby jacking up the casting located in the lower mold cavity 307, and then separating the casting from the lower mold cavity 307, making the casting connected to the inner wall of the upper mold cavity 411. At the same time, the electric push rod 402 is started to shorten, driving the moving mold body 410 to move upward, thereby driving multiple upper mold cavities 411 to move upward. When the upper mold cavity 411 moves upward a certain distance, an external collection device is moved to the bottom of the upper mold cavity 411, and the second cylinder 407 is started to extend, driving the second pressing plate 408 to move downward and embed into the interior of the second card slot 409. Among them, the second card slot 409 also plays a role in limiting the second pressing plate 408. Through the pressing of the second pressing plate 408, the second sliding plate 405 moves downward along multiple second limiting rods 404, and at the same time, the four second springs 413 are compressed. The movement of the second sliding plate 405 drives multiple upper ejector rods 406 to move downward, thereby ejecting the casting located in the upper mold cavity 411, making it fall into the external collection device. Then, the controller 6 is used to start the first cylinder 308 and the second cylinder 407 to shorten them respectively, driving the first pressing plate 309 and the second pressing plate 408 to reset respectively, so that the first sliding plate 304 and the second sliding plate 405 are respectively reset under the elastic force of the four first springs 312 and the four second springs 413, and then driving multiple upper ejector rods 406 and lower ejector rods 305 to reset respectively, that is, the two-way automatic ejection and reset of the casting mold are completed. Through the action of the first ejection assembly 3 and the second ejection assembly 4, the automation efficiency of the casting production line is improved, and the standby time of the mold is short, so that the temperature of the mold will not change significantly, solving the problem of long standby time and low working efficiency in the prior art when traditional molds take out products., Embodiment 2

[0033] As Figure 1 and Figures 7-8 shown, four limiting components 5 are arranged between the outer surfaces of the static mold body 306 and the moving mold body 410. The four limiting components 5 each include a lower reset rod 501. The bottoms of the four lower reset rods 501 are fixedly connected to the top of the static mold body 306. Taper blocks 502 are arranged on the inner bottom surfaces of the four lower reset rods 501. Connecting grooves 503 are formed near the bottoms of the outer surfaces of the four lower reset rods 501. Mounting holes 504 are formed near the bottoms of the inner walls of the four lower reset rods 501. Third dampers 505 are arranged on the inner walls of the four mounting holes 504. Third springs 506 are arranged on the outer surfaces of the four third dampers 505. One ends of the four third dampers 505 are fixedly connected to the outer surfaces of the four taper blocks 502 respectively. One ends of the four third springs 506 are fixedly connected to the inner walls of the four mounting holes 504 respectively. The other ends of the four third springs 506 are fixedly connected to the outer surfaces of the four taper blocks 502 respectively. The outer surfaces of the four taper blocks 502 are slidably connected to the interiors of the four connecting grooves 503 respectively. Four upper reset rods 507 are fixed to the bottom of the moving mold body 410. The outer surfaces of the four upper reset rods 507 are slidably connected to the interiors of the four lower reset rods 501 respectively. Touch plates 508 are fixedly installed on the outer surfaces of the four lower reset rods 501 respectively.

[0034] In this embodiment, after the product in the casting mold is removed from its interior, the electric push rod 402 is started again to make it extend, driving the mounting bracket 403 to move downward, thereby driving the moving mold body 410 to move downward, and further enabling the four upper reset rods 507 to be inserted into the interiors of the four lower reset rods 501 respectively. Among them, as Figure 7 shown, the cross-section of the taper block 502 is composed of an inclined surface and a horizontal surface. When the four upper reset rods 507 move downward, they drive the four taper blocks 502 to move outward along the directions of the four connecting grooves 503 respectively, so that the four third springs 506 are stretched. As Figure 8 shown, when the flat part of the taper block 502 is in full contact with the bottom of the upper reset rod 507, the outer surface of the taper block 502 is exactly in full contact with the inner wall of the touch plate 508, that is, the moving mold body 410 completely coincides with the static mold body 306, which is convenient for the staff to observe. Through the action of the limiting component 5, the moving mold and the static mold of the casting mold are reset more accurately, further improving the precision of the casting of the casting mold.

[0035] Usage method and working principle of this device: During the casting production process, when it is necessary to remove the casting from the mold, start the first cylinder 308 to make it extend, drive the first pressing plate 309 to move upward, and then move it into the first clamping groove 310. The first pressing plate 309 continues to move upward driven by the first cylinder 308, thereby driving the first sliding plate 304 to move upward, and further causing the four first springs 312 to be compressed. The upward movement of the first sliding plate 304 drives multiple lower ejector rods 305 to move upward, thereby jacking up the casting located in the lower mold cavity 307, and further separating the casting from the lower mold cavity 307, making the casting connected to the inner wall of the upper mold cavity 411. At the same time, start the electric push rod 402 to make it shorten, drive the moving mold body 410 to move upward, and then drive multiple upper mold cavities 411 to move upward. After the upper mold cavity 411 moves upward a certain distance, move the external collection device to the bottom of the upper mold cavity 411, start the second cylinder 407 to make it extend, drive the second pressing plate 408 to move downward and insert it into the second clamping groove 409. Through the pressing of the second pressing plate 408, the second sliding plate 405 moves downward along multiple second limiting rods 404, and at the same time, the four second springs 413 are compressed. The movement of the second sliding plate 405 drives multiple upper ejector rods 406 to move downward, thereby ejecting the casting located in the upper mold cavity 411, making it fall into the external collection device. Then, start the first cylinder 308 and the second cylinder 407 through the controller 6 to make them shorten respectively, drive the first pressing plate 309 and the second pressing plate 408 to reset respectively, so that the first sliding plate 304 and the second sliding plate 405 are reset under the elastic force of the four first springs 312 and the four second springs 413 respectively, and further drive multiple upper ejector rods 406 and lower ejector rods 305 to reset respectively, that is, the two-way automatic ejection and reset of the casting mold are completed. When the product in the casting mold is removed from its interior, start the electric push rod 402 again to make it extend, drive the mounting bracket 403 to move downward, and then drive the moving mold body 410 to move downward, so that the four upper reset rods 507 are respectively inserted into the four lower reset rods 501. When the four upper reset rods 507 move downward, drive the four inclined blocks 502 to move outward along the directions of the four connecting grooves 503 respectively, so that the four third springs 506 are stretched. As Figure 8 shown, when the flat part of the inclined block 502 is in full contact with the bottom of the upper reset rod 507, the outer surface of the inclined block 502 is exactly in full contact with the inner wall of the touch plate 508, that is, the moving mold body 410 completely coincides with the static mold body 306.
