Description

Technical Field

[0001] The invention relates to the technical field of embryo removal by injection molding machine, in particular to an embryo removal mechanism of an overturned double-end mold core type injection molding machine and a use method thereof. Background Art

[0002] The double-end core injection molding machine is different from the traditional injection molding machine. It is equipped with two cores, located at both ends of the mold. This design allows two plastic parts to be molded at the same time during the injection molding process, greatly improving production efficiency. The matching flip mechanism can flip the mold 180 degrees, so that the two ends of the core can be alternately injected and demolded. Compared with the traditional single-core injection molding machine, it can produce more plastic parts in the same time.

[0003] In the existing embryo removal process of the injection molding machine, for some injection molded products with complex shapes and thin walls, if the temperature is still high after demolding, they are prone to deformation during the subsequent embryo removal and transfer process due to factors such as thin walls and internal stress. However, the current blowing equipment is basically separated from the embryo removal equipment, and the blowing equipment is controlled to open by a control valve, which requires the use of multiple driving devices.

[0010] Preferably, a plurality of support rods are fixedly connected to the bottom of the mounting plate, a reinforcing plate is fixedly connected between one ends of the plurality of support rods, and the reinforcing plate is mounted on the front surface of the transverse linear rail.

[0011] Preferably, an air pump is arranged on the top of the base, the output end of the air pump is fixedly connected to an air supply pipe, one end of the air supply pipe is fixedly connected to a connecting pipe, both ends of the connecting pipe are fixedly connected to two guide pipes, and one end of each guide pipe is fixedly connected to the other end of each air nozzle.

[0012] Preferably, the embryo retrieval assembly includes a fixed round seat, which is fixedly installed on the inner wall of the mounting hole, and a plurality of movable rods are slidably embedded inside the fixed round seat, and a series hole is opened on the outer surface of each movable rod near one end, and a connecting ring is movably connected between the inner walls of the plurality of series holes, and a plurality of reinforcement rods are fixedly connected to the outer surface of the connecting ring, and a push-pull rod is fixedly connected between one ends of the plurality of reinforcement rods, and the push-pull rod is fixedly installed on the outer surface of the connecting plate, and limiting rings are fixedly connected to both ends of each of the series holes, and the limiting rings are used to limit the connecting rings.

[0015] A method for using a embryo removal mechanism of a flip double-end mold core type injection molding machine comprises the following steps: S1. The hydraulic rod performs telescopic movement according to the command of the external control system. When the hydraulic rod is extended, it pushes the connecting plate to move away from the mounting plate, and at the same time drives the clamping claws in the embryo removal assembly to contract. When the hydraulic rod contracts, it pulls the connecting plate to move toward the mounting plate, and at the same time drives the clamping claws in the embryo removal assembly to expand. The air pump is started, and the compressed air is delivered to the air pipe through the output end. The air pipe transmits the gas to the connecting pipe, and the connecting pipe then diverts the gas to each guide pipe. The multiple guide pipes deliver the gas to each air nozzle respectively. When the gas enters the air nozzle, it will be ejected from the multiple air outlets at one end of the air nozzle; S2. When the connecting plate is away from the mounting plate, the blank is clamped by the blank removal assembly. At the same time, the air blocking block is supported by the fixing rod and the reinforcing block and keeps a certain distance from the air outlet, so that the gas can be ejected smoothly from the air outlet. When the blank removal assembly is unfolded, since the connecting hole on the connecting plate is connected to the air jet assembly, when the connecting plate moves, the air jet nozzle and the air blocking block will be driven to move together. When the air blocking block moves to the position corresponding to the air outlet, since the outer diameter of the air blocking block matches the inner diameter of the air outlet, the air blocking block will be inserted into the air outlet to prevent the gas from being ejected from the air outlet. S3. When the embryo removal operation is required, the connecting plate starts to move, driving the push-pull rod to move. The movement of the push-pull rod will directly drive the connecting ring to move in the serial holes of the multiple movable rods. The movement of the connecting ring will push the movable rod to slide in the fixed round seat. The sliding of the movable rod will drive the movable block to move through the connecting rod. The movable block is rotatably connected to one end of the positioning frame, and the corner of the movable block is rotatably connected to the other end of the movable rod through the connecting rod. When the movable rod moves, the movable block will rotate through the connecting rod. A clamping claw is installed inside the movable block through bolts. The rotation of the movable block will drive the clamping claw to perform corresponding actions. The clamping claw gradually changes from an open state to a closed state, thereby clamping the embryo; S4. The components cooperating with the vertical linear rail are moved to drive the horizontal linear rail connected thereto and the embryo-taking mechanism installed on the horizontal linear rail to adjust their positions in the vertical direction. The components cooperating with the horizontal linear rail are moved left and right on the horizontal linear rail to achieve the horizontal position adjustment of the embryo-taking mechanism.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. When in use, the hydraulic rod is the key part of the linkage assembly. The hydraulic rod can perform telescopic movements according to the instructions of the external control system, and at the same time drive the clamping claws in the embryo removal assembly to perform a grabbing operation. At this time, the air pump is started. When the connecting plate is away from the mounting plate, the embryo removal assembly clamps the embryo. At the same time, the air blocking block is supported by the fixed rod and the reinforcing block and keeps a certain distance from the air outlet. The gas can be ejected smoothly from the air outlet. Therefore, when the hydraulic rod is started, the grabbing of the embryo and the blowing of the embryo can be controlled at the same time. When the embryo removal assembly is unfolded, since the connecting hole on the connecting plate is connected to the jet assembly, when the connecting plate moves, it will drive the jet nozzle and the air blocking block to move together. The air blocking block will be inserted into the air outlet to prevent the gas from being ejected from the air outlet, thereby realizing the control of the jet. 2. When in use, when the height of the embryo taking mechanism needs to be adjusted, the components cooperating with the vertical linear rail are moved up and down along the vertical linear rail, thereby driving the horizontal linear rail connected thereto and the embryo taking mechanism installed on the horizontal linear rail to adjust their positions in the vertical direction. When the horizontal position of the embryo taking mechanism needs to be adjusted, the horizontal linear rail installed on the vertical linear rail plays a role, and the embryo taking mechanism moves left and right on the horizontal linear rail through the components cooperating with the horizontal linear rail, thereby realizing the horizontal position adjustment of the embryo taking mechanism; 3. During use, when the hydraulic rod drives the connecting plate to start moving and drives the push-pull rod to move, the movement of the push-pull rod will directly drive the connecting ring to move in the serial holes of multiple movable rods. The movement of the connecting ring will exert force on the movable rod, thereby pushing the movable rod to slide in the fixed round seat. The sliding of the movable rod will drive the movable block to move through the connecting rod. The movable block is equipped with clamping claws by bolts. The rotation of the movable block will drive the clamping claws to perform corresponding actions. The clamping claws gradually change from an open state to a closed state to achieve clamping of the blank. At this time, the rubber tooth plate can increase the friction between the clamping claws and the blank, ensuring that the blank will not slip easily during the clamping process, thereby improving the stability and reliability of the clamping. During the clamping process, the limiting roller can limit the position of the blank to prevent the blank from shifting during the clamping process, and also help reduce damage to the surface of the blank during the clamping process.

Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Example 1: Reference Figure 1 - Fig.13 As shown, the present invention provides a technical solution: a flip double-end core injection molding machine embryo removal mechanism, including a support component 1 and a linkage component 3, the linkage component 3 includes a mounting plate 301, the outer surface of the mounting plate 301 is provided with a plurality of mounting holes 304, the inner wall of each mounting hole 304 is fixedly connected with an embryo removal component 4, one side of each embryo removal component 4 is fixedly connected to one side of a connecting plate 303, a hydraulic rod 302 is arranged in the middle of the outer surface of the mounting plate 301, one end of the hydraulic rod 302 is fixedly connected with a connecting plate 303, the outer surface of the connecting plate 303 is provided with a plurality of connecting holes 306, the inner wall of each connecting hole 306 is fixedly connected with an injection component 2, each injection component 2 includes an air nozzle 205 and a reinforcement block 209, the outer surface of each air nozzle 205 is provided with a plurality of air outlets 206 near one end, the outer surface of each reinforcement block 209 is fixedly connected with a plurality of fixing rods 208, each fixed One end of the rod 208 is fixedly connected to an air blocking block 207, and the outer diameter of each air blocking block 207 matches the inner diameter of the air outlet 206 at the corresponding position. Two limit frames 305 are fixedly connected to the outer surface of the mounting plate 301, and the two limit frames 305 slide through the connecting plate 303 to the outside respectively, and the limit frames 305 are used to maintain the balance between the connecting plate 303 and the mounting plate 301. A plurality of support rods 307 are fixedly connected to the bottom of the mounting plate 301, and a reinforcing plate 308 is fixedly connected between one ends of the plurality of support rods 307, and the reinforcing plate 308 is installed on the front surface of the horizontal linear rail 103. An air pump 201 is arranged on the top of the base 5, and an output end of the air pump 201 is fixedly connected to an air supply pipe 202, and one end of the air supply pipe 202 is fixedly connected to a connecting pipe 203, and both ends of the connecting pipe 203 are fixedly connected to two guide pipes 204, and one end of each guide pipe 204 is fixedly connected to the other end of each air nozzle 205.

[0021] In this embodiment, when in use, the embryo taking mechanism of the entire injection molding machine is mainly composed of a support component 1, an injection component 2, a linkage component 3 and an embryo taking component 4. The embryo taking mechanism starts to work after the injection molding machine completes the injection molding process. The hydraulic rod 302 is a key part of the linkage component 3. The hydraulic rod 302 can perform telescopic movements according to the instructions of the external control system. When the hydraulic rod 302 is extended, the connecting plate 303 is pushed to move away from the mounting plate 301, and at the same time, the clamping claw 411 in the embryo taking component 4 is driven to contract. When the hydraulic rod 302 contracts, the connecting plate 303 is pulled close to the mounting plate 301. The connecting plate 303 is moved in the same direction as the mounting plate 301, and the clamping claws 411 in the embryo taking component 4 are expanded. At this time, the limiting frame 305 plays a role of limiting the position, so that the connecting plate 303 and the mounting plate 301 can maintain balance. During the movement of the connecting plate 303, the limiting frame 305 limits the moving direction of the connecting plate 303, so that the connecting plate 303 can only move in a direction parallel to the mounting plate 301, and prevents the connecting plate 303 from tilting or deflecting during the movement, thereby ensuring the working stability of the jet assembly 2 and the embryo taking component 4. By starting the air pump 201 on the top of the base 5, the compressed external air The gas is transmitted to the connecting pipe 203 through the gas transmission pipe 202. The connecting pipe 203 can divert the gas to each guide pipe 204 and each corresponding air nozzle 205, and then the gas is ejected from multiple air outlets 206 at one end of the air nozzle 205. When the connecting plate 303 is driven away from the mounting plate 301 by the hydraulic rod 302, the embryo removal component 4 will clamp the embryo. At the same time, the air blocking block 207 is supported by the fixing rod 208 and the reinforcing block 209 and is separated from the inner wall of the air outlet 206. The gas can be ejected from the air outlet 206. The air outlet 206 is set to be inclined, so the blown air flow is also It is diagonally downward, so when the hydraulic rod 302 is started, the grabbing of the billet and the blowing of the billet can be controlled at the same time. When the billet assembly 4 is unfolded, since the connecting hole 306 on the connecting plate 303 is connected to the jet assembly 2, when the connecting plate 303 moves, it will drive the jet nozzle 205 and the air blocking block 207 to move together. When the air blocking block 207 moves to the position corresponding to the air outlet 206, since the outer diameter of the air blocking block 207 matches the inner diameter of the air outlet 206, the air blocking block 207 will be inserted into the air outlet 206 to prevent the gas from being ejected from the air outlet 206, thereby realizing the control of the jet.

[0022] Embodiment 2: Figure 1 - Fig.13As shown, the support assembly 1 includes a support plate 101, the outer surface of the support plate 101 is fixedly connected with a vertical linear rail 102, and the vertical linear rail 102 is used to adjust the height of the embryo retrieval mechanism, the outer surface of the vertical linear rail 102 is fixedly connected with a transverse linear rail 103, and the transverse linear rail 103 is used to adjust the transverse position of the embryo retrieval mechanism, the bottom of the support plate 101 is fixedly connected with a base 5, the vertical linear rail 102 is fixedly connected to the top of the base 5, and the base 5 is used to maintain stability during the embryo retrieval process.

[0023] In this embodiment, when it is necessary to adjust the height of the embryo taking mechanism during use, the components cooperating with the vertical linear rail 102 are operated, and these components move up and down along the vertical linear rail 102, thereby driving the horizontal linear rail 103 connected thereto and the embryo taking mechanism installed on the horizontal linear rail 103 to adjust their positions in the vertical direction. When it is necessary to adjust the horizontal position of the embryo taking mechanism, the horizontal linear rail 103 installed on the vertical linear rail 102 plays a role, and the embryo taking mechanism moves left and right on the horizontal linear rail 103 through the components cooperating with the horizontal linear rail 103, so as to realize the horizontal position adjustment of the embryo taking mechanism. During the entire adjustment process, the base 5 fixedly connected to the bottom of the support plate 101 plays a role in maintaining the stability of the embryo retrieval process. The base 5 relies on its own weight and structural stability to ensure that when the embryo retrieval mechanism adjusts its height and lateral position, the entire cross slide system will not shake or become unstable, thereby ensuring the accuracy and reliability of the embryo retrieval operation. The vertical linear rail 102 and the horizontal linear rail 103 have similar operating principles. Both are driven by a motor to rotate the lead screw. Under the limit of the limit long rods on both sides of the lead screw, the movable plate can achieve reciprocating motion on the lead screw, and both motors run forward and reverse.

[0024] Embodiment three: Figure 1 - Fig.13As shown, the embryo removal component 4 includes a fixed round seat 401, which is fixedly installed on the inner wall of the installation hole 304, and a plurality of movable rods 402 are slidably embedded in the fixed round seat 401. A series hole 403 is opened on the outer surface of each movable rod 402 near one end, and a connecting ring 404 is movably connected between the inner walls of the plurality of series holes 403. A plurality of reinforcement rods 405 are fixedly connected to the outer surface of the connecting ring 404, and a push-pull rod 406 is fixedly connected between one ends of the plurality of reinforcement rods 405. The push-pull rod 406 is fixedly installed on the outer surface of the connecting plate 303, and a limiting ring 415 is fixedly connected to both ends of each series hole 403, and the limiting ring 415 is used to limit the connecting ring 404. A plurality of positioning blocks 407 are fixedly connected to one side near the outer edge, a positioning frame 408 is installed on the outer surface of each positioning block 407, a movable block 409 is rotatably connected to one end of each positioning frame 408, a connecting rod 410 is rotatably connected between the corner of each movable block 409 and the other end of each movable rod 402, a clamping claw 411 is installed inside each movable block 409 by bolts, a rubber tooth plate 412 is fixedly connected to the outer surface of each clamping claw 411, and the rubber tooth plate 412 is used to increase the friction between the clamping claw 411 and the blank, one end of each clamping claw 411 is fixedly connected to a fixing frame 413, and a limiting roller 414 is rotatably sleeved on the middle of the outer surface of each fixing frame 413.

[0025] In this embodiment, when in use, when the hydraulic rod 302 drives the push-pull rod 406 to move, it can drive the clamping claw 411 to grab the blank. The specific implementation method is: in the initial state, the connecting plate 303 is in a specific position, and the push-pull rod 406 is also in a fixed position accordingly. At this time, the connecting ring 404 is connected to the push-pull rod 406 through a plurality of reinforcement rods 405. The connecting ring 404 is located in the series holes 403 of the plurality of movable rods 402. The movable rods 402 are basically in a stationary state in the fixed round seat 401. The positioning frame 408, movable block 409, connecting rod 410 and clamping claw 411 on the positioning block 407 are also in a relatively stable state. The clamping claw 411 is in an open state, ready for embryo retrieval operation. When embryo retrieval operation is required, the connecting plate 303 starts to move, driving the push-pull rod 406 to move. The movement of the push-pull rod 406 drives the connecting ring 404 to move in the serial holes 403 of the multiple movable rods 402. Therefore, the movement of the connecting ring 404 pushes the movable rod 402 to slide in the fixed round seat 401. The limiting ring 415 can prevent the connecting ring 404 from slipping off the movable rod 402 to ensure the stability of the connection. The movable rod 402 will drive the movable block 409 to move through the connecting rod 410. The movable block 409 is rotatably connected to one end of the positioning frame 408. Since the corner of the movable block 409 is rotatably connected to the other end of the movable rod 402 through the connecting rod 410, when the movable rod 402 moves, the movable block 409 will rotate through the connecting rod 410, so that the clamping claw 411 performs a corresponding action. It gradually changes from an open state to a closed state to achieve clamping of the blank. At this time, the rubber tooth plate 412 on the outer surface of the clamping claw 411 can increase the friction between the clamping claw 411 and the blank, ensuring that the blank will not easily slip off during the clamping process. A limiting roller 414 made of hard rubber is rotatably sleeved on the middle of the outer surface of the fixed frame 413 at one end of the clamping claw 411. During the clamping process, the limiting roller 414 can prevent the blank from shifting during the clamping process and help reduce damage to the surface of the blank during the clamping process.

[0026] The use method and working principle of this device: The working process of the flip double-end core injection molding machine is different from that of the traditional injection molding machine. During injection molding, first, the plastic particles are added to the hopper of the injection molding machine to melt into a liquid state. Then, the liquid plastic is injected into the core at one end of the mold through the injection system of the injection molding machine to form the shape of the plastic part. At the same time, the core at the other end of the mold can be cooled and solidified to prepare for the next injection molding. When the plastic part in the core at one end is cooled and solidified, the flip mechanism is started to horizontally swap the cores at both ends of the mold. At this time, the core originally used for injection molding and the core originally used for cooling are exchanged. After that, the blank is taken out of the core and a new injection molding cycle is started at the same time. The working principle of taking the blank is: when in use, the entire injection molding The embryo taking mechanism of the machine is mainly composed of a support component 1, an injection component 2, a linkage component 3 and an embryo taking component 4. The embryo taking mechanism starts to work after the injection molding machine completes the injection molding process. The hydraulic rod 302 is a key part of the linkage component 3. The hydraulic rod 302 can be extended and retracted according to the command of the external control system. When the hydraulic rod 302 is extended, the connecting plate 303 is pushed to move away from the mounting plate 301, and the clamping claw 411 in the embryo taking component 4 is driven to contract. When the hydraulic rod 302 contracts, the connecting plate 303 is pulled to move toward the mounting plate 301, and the clamping claw 411 in the embryo taking component 4 is driven to expand. At this time, the limit frame 305 plays a role of position limitation, which can keep the connecting plate 303 and the mounting plate 301 flat. During the movement of the connecting plate 303, the limiting frame 305 limits the moving direction of the connecting plate 303, so that the connecting plate 303 can only move in a direction parallel to the mounting plate 301, preventing the connecting plate 303 from tilting or deflecting during the movement, thereby ensuring the working stability of the jet assembly 2 and the embryo removal assembly 4. By starting the air pump 201 on the top of the base 5, the compressed external air is transmitted to the connecting pipe 203 through the air pipe 202. The connecting pipe 203 can divert the gas to each guide pipe 204 and each corresponding air nozzle 205, and then spray it out from the multiple air outlets 206 at one end of the air nozzle 205. When the connecting plate 303 is driven away from the mounting plate 301 by the hydraulic rod 302, the embryo removal assembly 4 will clamp the blank. At the same time, the air blocking block 207 is separated from the inner wall of the air outlet 206 under the support of the fixing rod 208 and the reinforcing block 209, and the gas can be ejected from the air outlet 206. The air outlet 206 is arranged to be inclined, so the air flow blown out is also directed obliquely downward. Therefore, when the hydraulic rod 302 is started, the grabbing of the blank and the blowing of the blank can be controlled at the same time. When the blank assembly 4 is unfolded, since the connecting hole 306 on the connecting plate 303 is connected to the air injection assembly 2, when the connecting plate 303 moves, it will drive the air nozzle 205 and the air blocking block 207 to move together. When the air blocking block 207 moves to the position corresponding to the air outlet 206, since the outer diameter of the air blocking block 207 matches the inner diameter of the air outlet 206,The air blocking block 207 will be inserted into the air outlet 206 to prevent the gas from being ejected from the air outlet 206. When in use, when it is necessary to adjust the height of the embryo taking mechanism, the components cooperating with the vertical linear rail 102 are actuated, and these components move up and down along the vertical linear rail 102, thereby driving the horizontal linear rail 103 connected thereto and the embryo taking mechanism installed on the horizontal linear rail 103 to adjust their positions in the vertical direction. When it is necessary to adjust the horizontal position of the embryo taking mechanism, the horizontal linear rail 103 installed on the vertical linear rail 102 plays a role, and the embryo taking mechanism moves left and right on the horizontal linear rail 103 through the components cooperating with the horizontal linear rail 103, so as to realize the horizontal position adjustment of the embryo taking mechanism. During the whole adjustment process, the bottom of the support plate 101 The fixedly connected base 5 plays a role in maintaining the stability of the embryo retrieval process, and the operating principles of the vertical linear rail 102 and the horizontal linear rail 103 are similar. The motor drives the screw rod to rotate. Under the limit of the limit long rods on both sides of the screw rod, the movable plate can realize reciprocating motion on the screw rod. The two motors are both running forward and reverse. In the initial state, the connecting plate 303 is in a specific position, and the push-pull rod 406 is also in a fixed position accordingly. At this time, the connecting ring 404 is connected to the push-pull rod 406 through a plurality of reinforcement rods 405. The connecting ring 404 is located in the serial holes 403 of the plurality of movable rods 402. The movable rods 402 are basically in a stationary state in the fixed round seat 401. The positioning frames 408 and movable blocks 407 on each positioning block 407 are 9. The connecting rod 410 and the clamping claw 411 and other components are also in a relatively stable state. The clamping claw 411 is in an open state, ready for embryo retrieval. When the embryo retrieval operation is required, the connecting plate 303 starts to move, driving the push-pull rod 406 to move. The movement of the push-pull rod 406 will drive the connecting ring 404 to move in the serial holes 403 of the multiple movable rods 402. Therefore, the movement of the connecting ring 404 will push the movable rod 402 to slide in the fixed round seat 401. The limiting ring 415 can prevent the connecting ring 404 from slipping off the movable rod 402 to ensure the stability of the connection. The movable rod 402 will drive the movable block 409 to move through the connecting rod 410. The movable block 409 is rotatably connected to one end of the positioning frame 408. The corner of the movable block 409 is rotatably connected to the other end of the movable rod 402 through the connecting rod 410. When the movable rod 402 moves, the movable block 409 will rotate through the connecting rod 410, so that the clamping claw 411 will perform corresponding actions, and the clamping claw 411 will gradually change from an open state to a closed state to achieve the clamping of the blank. At this time, the rubber tooth plate 412 on the outer surface of the clamping claw 411 can increase the friction between the clamping claw 411 and the blank, ensuring that the blank will not slip easily during the clamping process, and a limiting roller 414 made of hard rubber is rotatably sleeved in the middle of the outer surface of the fixed frame 413 at one end of the clamping claw 411. During the clamping process, the limiting roller 414 can prevent the blank from deflecting during the clamping process.

A method for using a embryo removal mechanism of a flip double-end mold core type injection molding machine, characterized in that: The embryo removal mechanism of the flip double-end mold core type injection molding machine according to claim 9 is used, comprising the following steps: S1, the hydraulic rod (302) performs a telescopic action according to the command of the external control system. When the hydraulic rod (302) is extended, it pushes the connecting plate (303) to move in a direction away from the mounting plate (301), and at the same time drives the clamping claw (411) in the embryo removal component (4) to contract. When the hydraulic rod (302) contracts, it pulls the connecting plate (303) to move in a direction close to the mounting plate (301), and at the same time drives the clamping claw (411) in the embryo removal component (4) to expand. The air pump (201) is started, and the compressed air is transported to the air supply pipe (202) through the output end. The air supply pipe (202) transmits the gas to the connecting pipe (203). The connecting pipe (203) then diverts the gas to each guide pipe (204). The multiple guide pipes (204) respectively transport the gas to each air nozzle (205). When the gas enters the air nozzle (205), it is ejected from the multiple air outlets (206) at one end of the air nozzle (205); S2, when the connecting plate (303) is away from the mounting plate (301), the embryo removal assembly (4) clamps the embryo material, and at the same time, the air blocking block (207) is supported by the fixing rod (208) and the reinforcing block (209) and maintains a certain distance from the gas outlet (206), so that the gas can be smoothly ejected from the gas outlet (206). When the embryo removal assembly (4) is unfolded, since the connecting hole (306) on the connecting plate (303) is connected to the air injection assembly (2), when the connecting plate (303) moves, it will drive the air injection nozzle (205) and the air blocking block (207) to move together. When the air blocking block (207) moves to a position corresponding to the gas outlet (206), since the outer diameter of the air blocking block (207) matches the inner diameter of the gas outlet (206), the air blocking block (207) will be inserted into the gas outlet (206) to prevent the gas from being ejected from the gas outlet (206); S3. When embryo retrieval is required, the connecting plate (303) starts to move, driving the push-pull rod (406) to move. The movement of the push-pull rod (406) directly drives the connecting ring (404) to move in the serial holes (403) of the plurality of movable rods (402). The movement of the connecting ring (404) drives the movable rod (402) to slide in the fixed round seat (401). The sliding of the movable rod (402) drives the movable block (409) to move through the connecting rod (410). The movable block (409) and the positioning frame (401) are connected. 8) One end is rotatably connected, and the corner of the movable block (409) is rotatably connected to the other end of the movable rod (402) through a connecting rod (410). When the movable rod (402) moves, the movable block (409) is rotated through the connecting rod (410). A clamping claw (411) is installed inside the movable block (409) through bolts. The rotation of the movable block (409) drives the clamping claw (411) to perform corresponding actions, and the clamping claw (411) gradually changes from an open state to a closed state, thereby clamping the blank; S4. The components cooperating with the vertical linear rail (102) are moved, thereby driving the horizontal linear rail (103) connected thereto and the embryo taking mechanism installed on the horizontal linear rail (103) to adjust their positions in the vertical direction. The components cooperating with the horizontal linear rail (103) are moved left and right on the horizontal linear rail (103), thereby achieving the horizontal position adjustment of the embryo taking mechanism.
