The upper end of the cross-shaped extrusion block 19 is arranged in an arc shape. As the molten liquid is continuously injected, the air in the molding cavity 16 enters to the air storage cavity 4 through a plurality of groups of air holes 26.

[0034] Embodiment 2:

[0035] On the basis of Example 1, in order to prevent the gas entering the gas storage chamber 4 from being discharged immediately after the movable template 1 is separated from the fixed template 15, the extrusion pushing mechanism includes an extrusion plate 21, which is movably connected to the movable template 1, one end of the extrusion plate 21 is fixedly connected to the T-block 22, and the other end extends into the clearance chamber 25 and contacts the cross-shaped extrusion block 19. The contact end of the extrusion plate 21 and the cross-shaped extrusion block 19, as well as the lower end of the cross-shaped extrusion block 19 are arranged in an inclined shape, and the cross-shaped extrusion block 19 is slidably connected to the clearance chamber 25. The upper end of the cross-shaped extrusion block 19 extends into the air storage chamber 4, and the upper end of the cross-shaped extrusion block 19 is arranged in an arc shape. The push plate 3 moves to drive the limit rod 8 to move synchronously. When the molten liquid fills the molding cavity 16, the push plate 3 moves to the position of the cross-shaped extrusion block 19 and extrudes it. After the cross-shaped extrusion block 19 is extruded, it drives the extrusion plate 21 to move. The movement of the extrusion plate 21 drives the T-shaped block 22 to move. The movement of the T-shaped block 22 drives the baffle 11 connected thereto to start moving. At this time, the air vent 26 is staggered from the position of the air guide hole 2.

[0036] The limiting mechanism includes a T-shaped rod 14, which is slidably connected to the connecting cavity 6, which is provided in the movable template 1, and the lower end of the T-shaped rod 14 extends into the external environment, and the upper end of the connecting cavity 6 is connected to the guide groove 5. A T-shaped clamping rod 29 is movably connected to the upper end of the T-shaped rod 14, and the upper end of the T-shaped clamping rod 29 is arranged in an arc shape, and the T-shaped clamping rod 29 is clamped in the limiting hole 24. In the process of the movable template 1 and the fixed template 15 contacting, several groups of T-shaped rods 14 will be squeezed inward by the fixed template 15, and the movement of the T-shaped rod 14 drives the T-shaped clamping rod 29 to move synchronously, and the second spring 7 is compressed at the same time. When the upper end of the T-shaped clamping rod 29 contacts the guide groove 5, at this time, as the T-shaped rod 14 continues to move, the T-shaped clamping rod 29 will move inward along the spring cavity 28, so that the first spring 27 is compressed;

[0037] The lower end of the T-shaped clamping rod 29 is slidably connected to the spring cavity 28, and the spring cavity 28 is opened in the upper end of the T-shaped rod 14. The first spring 27 is fixedly connected in the spring cavity 28, and the other end of the first spring 27 is fixedly connected to the T-shaped clamping rod 29. The second spring 7 is sleeved on the outer side of the T-shaped clamping rod 29. One end of the second spring 7 is fixedly connected to the connecting cavity 6, and the other end is fixedly connected to the T-shaped rod 14. When the injection molding is completed, the movable template 1 is away from the fixed template 15. At this time, under the elastic force of the second spring 7, the T-shaped rod 14 will move outward, and the T-shaped rod 14 will not move during the initial movement. The T-shaped clamping rod 29 is disengaged from the limiting hole 24. When the T-shaped clamping rod 29 moves to the initial position, the T-shaped clamping rod 29 is disengaged from the limiting hole 24 as the T-shaped rod 14 moves, so that the movable plate 1 is away from one end of the fixed plate 15, and the gas is discharged from the gas storage chamber 4. The movement of the T-shaped rod 14 drives the T-shaped clamping rod 29 to move synchronously. When the T-shaped rod 14 stops moving, the T-shaped clamping rod 29 is disengaged from the limiting hole 24. At this time, under the elastic force of the connecting spring 9, the push plate 3 moves quickly and pushes the gas to move.

The lower ends of the several component cavities 16 are connected with the injection cavity 17. The injection cavity 17 is opened in the fixed template 15. The lower end of the fixed template 15 is fixedly connected with an injection connecting pipe 18. The upper end of the injection connecting pipe 18 is connected to the injection cavity 17. The molten liquid can be introduced into the injection connecting pipe 18 through the injection connecting pipe 18, and the molten liquid enters the molding cavity 16 through the injection cavity 17.

[0039] In addition, in order to achieve the above-mentioned purpose, the present invention also provides a cooling treatment equipment, which is used for the above-mentioned improved culture dish mold with increased air permeability, including a cooling device 30, and the output end of the cooling device 30 is fixedly connected to a cooling pipe 31, and the cooling pipe 31 extends into the fixed mold plate 15 away from the end of the cooling device 30, and is connected to the cooling cavity 12, and the cooling cavity 12 is opened in the fixed mold plate 15. After the injection molding is completed, the cooling device 30 is opened to transport the coolant to the cooling pipe 31, and the coolant enters the cooling cavity 12 through the cooling pipe 31 to cool the molten liquid in the molding cavity 16.

[0040] In addition, in order to achieve the above object, the present invention also provides a cooling treatment method, which is used for the above cooling treatment equipment, comprising:

[0041] S1 drives the movable mold plate 1 to contact the fixed mold plate 15 through the injection molding equipment, and several groups of T-shaped rods 14 are squeezed inward by the fixed mold plate 15, so that the upper end of the T-shaped clamping rod 29 contacts the guide groove 5, and the molten liquid is introduced into the molding cavity 16 through the injection molding connecting pipe 18. With the injection of the molten liquid, the air in the molding cavity 16 enters the air guide hole 2 through several groups of air holes 26, and then enters the air storage cavity 4. The air pushes the push plate 3 to move. When the molten liquid fills the molding cavity 16, the push plate 3 moves to the position of the cross-shaped extrusion block 19 and squeezes it. After the cross-shaped extrusion block 19 is squeezed, it drives the extrusion plate 21 to move, so that the baffle 11 staggers the position of the air hole 26 and the air guide hole 2;

[0042] S2 After the push plate 3 contacts the cross-shaped extrusion block 19, the T-shaped extrusion rod 29 just moves to the position of the limiting hole 24, and is clamped into the limiting hole 24 under the elastic force of the second spring 7, so that the push plate 3 cannot move further. After the injection molding is completed, the cooling device 30 is turned on to transport the coolant to the cooling pipe 31, and the coolant enters the cooling chamber 12 through the cooling pipe 31 to cool the molten liquid in the molding chamber 16;

[0043] S3 After the injection molding is completed, the movable template 1 moves away from the fixed template 15. Under the elastic force of the second spring 7, the T-bar 14 moves to drive the T-bar 29 to move, so that the T-bar 29 is disengaged from the limiting hole 24. Under the elastic force of the connecting spring 9, the push plate 3 pushes the gas to move, and the baffle 11 returns to its original position so that the air hole 26 is aligned with the air guide hole 2 again. Under the push of the push plate 3, the gas is discharged into the external environment through the air guide hole 2, and the culture dish after injection molding can be taken out.

[0044] Working principle: when in use, the movable template 1 and the fixed template 15 are respectively installed together with the injection molding equipment, and the movable template 1 is driven by the injection molding equipment to move and contact with the fixed template 15. At this time, the molding block 13 enters the molding cavity 16. At the same time, in the process of the movable template 1 and the fixed template 15 contacting, several groups of T-shaped rods 14 are squeezed inward by the fixed template 15, and the movement of the T-shaped rod 14 drives the T-shaped clamping rod 29 to move synchronously, and at the same time, the second spring 7 is compressed. When the upper end of the T-shaped clamping rod 29 contacts the guide groove 5, at this time, as the T-shaped rod 14 continues to move, the T-shaped clamping rod 29 will move inward along the spring cavity 28, so that the first spring 27 is compressed;

[0045] The molten liquid can be introduced into the injection molding connecting tube 18 through the injection molding connecting tube 18, and the molten liquid enters into the molding cavity 16 through the injection molding cavity 17. At this time, as the molten liquid is continuously injected, the air in the molding cavity 16 enters into the air guide hole 2 through a plurality of groups of air vents 26, and the air entering into the air guide hole 2 enters into the air storage cavity 4. At this time, the air will push the push plate 3 to move, and the movement of the push plate 3 drives the limit rod 8 to move synchronously. When the molten liquid fills the molding cavity 16, the push plate 3 moves to the position of the cross-shaped extrusion block 19 and extrude it. After the cross-shaped extrusion block 19 is extruded, it drives the extrusion plate 21 to move, and the movement of the extrusion plate 21 drives the T-block 22 to move, and the movement of the T-block 22 drives the baffle 11 connected thereto to start moving. At this time, the air vent 26 is staggered from the position of the air guide hole 2 to prevent the molten liquid from entering the air guide hole 2;

[0046] In the process of the push plate 3 driving the limit rod 8 to move, since the limit rod 8 is arranged in an inclined shape at one end away from the push plate 3, after the limit rod 8 contacts with the T-shaped clamping rod 29, the T-shaped clamping rod 29 will be squeezed to move into the connecting cavity 6, and after the push plate 3 contacts with the cross-shaped extrusion block 19, the T-shaped extrusion rod 29 just moves to the position of the limit hole 24, and is clamped into the limit hole 24 under the elastic force of the second spring 7, so that the push plate 3 cannot move further;

[0047] When the injection molding is completed, the movable template 1 moves away from the fixed template 15. At this time, under the elastic force of the second spring 7, the T-bar 14 will move outward, and the movement of the T-bar 14 will drive the T-clamping rod 29 to move synchronously. When the T-bar 14 stops moving, the T-clamping rod 29 will be disengaged from the limiting hole 24. At this time, under the elastic force of the connecting spring 9, the push plate 3 moves quickly and pushes the gas to move. After the lower end of the push plate 3 is separated from the cross-shaped extrusion block 19, under the elastic force of the reset spring 23, the baffle 11 returns to its original position so that the air vent 26 is aligned with the air guide hole 2 again. At this time, under the push of the push plate 3, the gas is discharged into the external environment through the air guide hole 2, and the impurities that may exist in the air vent 26 and the air guide hole 2 are cleaned and blown away, and the culture dish after injection molding can be taken out.

[0048] The above embodiments are only used to help understand the method and core idea of ​​the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made to the present invention without departing from the principles of the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.

4. A cooling treatment method, used for the cooling treatment equipment according to claim 3, characterized in that: include: S1 drives the movable platen to contact the fixed platen through the injection molding equipment, and several groups of T-shaped rods are squeezed inward by the fixed platen, so that the upper end of the T-shaped clamping rod contacts the guide groove, and the molten liquid is introduced into the molding cavity through the injection molding connecting pipe. With the injection of the molten liquid, the air in the molding cavity enters the air guide hole through several groups of air holes, and then enters the air storage cavity. The air pushes the push plate to move. When the molten liquid fills the molding cavity, the push plate moves to the position of the cross-shaped extrusion block and squeezes it. After the cross-shaped extrusion block is squeezed, it drives the extrusion plate to move, so that the baffle plate staggers the position of the air vent and the air guide hole; S2 After the push plate contacts the cross-shaped extrusion block, the T-shaped extrusion rod moves to the position of the limit hole and is clamped into the limit hole under the elastic force of the second spring, so that the push plate cannot move further. After the injection molding is completed, the cooling device is turned on to transport the coolant to the cooling pipe. The coolant enters the cooling cavity through the cooling pipe to cool the molten liquid in the molding cavity. S3 When the injection molding is completed, the movable template moves away from the fixed template. Under the elastic force of the second spring, the T-bar moves and drives the T-bar to move, so that the T-bar disengages from the limiting hole. Under the elastic force of the connecting spring, the push plate pushes the gas to move, and the baffle returns to its original position so that the air vent is aligned with the air guide hole again. Under the push of the push plate, the gas is discharged into the external environment through the air guide hole, and the culture dish after injection molding can be taken out.
