[0024] The following is combined with Figures 1 to 5 This application is described in further detail.

[0025] The present application discloses a vertical locking and vertical shooting column-free injection molding machine.

[0026] Reference Figure 1-3, the vertical lock vertical shot column-free injection molding machine includes an injection molding machine body 10, a lifting injection molding module 20 and an injection mold 30; wherein the injection molding machine body 10 is provided with a workbench, the lifting injection molding module 20 is arranged on the injection molding machine body 10 and is located directly above the workbench, and the injection mold 30 includes an upper mold and a lower mold, the upper mold is fixedly arranged at the bottom of the lifting injection molding module 20, and the lower mold is fixedly arranged on the workbench of the injection molding machine body 10; during use, the upper mold and the lower mold are first driven by the lifting injection molding module 20 to close the mold, and then the lifting injection molding module 20 is used to perform an injection molding operation to form a plastic product, and then the upper mold and the lower mold are driven by the lifting injection molding module 20 to open the mold, and finally the molded plastic product is taken out from the lower mold by the staff, and this cycle is repeated, thereby completing the injection molding process for producing plastic products using a vertical injection molding machine; the above-mentioned injection molding machine body 10, the lifting injection molding module 20 and the injection mold 30 all adopt the existing technical structure and principle, which will not be repeated here.

[0027] In this embodiment, the vertical lock and vertical shot column-free injection molding machine also includes an odor removal module 40. The odor removal module 40 is located on the outer side of the lower mold, and in the process of the lifting injection molding module 20 driving the injection mold 30 to close or open the mold, the odor removal module 40 processes a large amount of pungent odor emitted from the inner cavity of the mold to avoid pollution to the factory environment and harm to the health of the workers.

[0028] Reference Figure 3-5 The deodorization mechanism specifically includes an air suction component 1, a first processing box 2, a second processing box 3, an exhaust component 4, an enhancement component 5 and a spray component 6; wherein, the air suction component 1 is fixedly arranged on one side of the injection molding machine body 10, and the air suction component 1 specifically includes an air suction chamber 11 fixedly arranged on the workbench of the injection molding machine body 10 and located on one side of the lower mold. The air suction chamber 11 is a hollow rectangular structure, and the air suction chamber 11 is provided with multiple groups of circular air suction ports 12 on the side facing the lower mold; the first processing box 2 is a hollow cylindrical structure, the first processing box 2 is fixedly arranged inside the injection molding machine body 10, the first processing box 2 is located directly below the workbench, and the first processing box 2 is connected to the output end of the air suction component 1 to realize the air transmission function ; The second processing box 3 is also a hollow cylindrical structure. The second processing box 3 is fixedly arranged inside the injection molding machine body 10. The second processing box 3 is located between the workbench and the first processing box 2, and the second processing box 3 is connected to the output end of the first processing box 2 to realize the air transmission function; the exhaust component 4 is an exhaust pump. The exhaust component 4 is fixedly arranged inside the injection molding machine body 10. The exhaust component 4 is located between the workbench and the second processing box 3. The exhaust component 4 is connected to the output end of the second processing box 3 to realize the air transmission function, and under the pumping action of the exhaust component 4, the pungent smell emitted from the inner cavity of the injection mold 30 flows through the suction component 1, the first processing box 2, and the second processing box 3 in sequence and is discharged by the exhaust component 4.

[0029] In the above, the first treatment box 2 is provided with a waste gas treatment liquid 8. The waste gas treatment liquid 8 adopts the plastic waste gas treatment liquid 8 in the prior art, which can effectively treat the irritating plastic smell in the air; the second treatment box 3 is provided with an activated carbon adsorption plate 9. The activated carbon adsorption plate 9 also adopts the filter plate structure made of activated carbon in the prior art, which can effectively treat the irritating plastic smell in the air. The pungent odor emitted from the inner cavity of the injection mold 30 flows through the suction component 1, the first treatment box 2, and the second treatment box 3 in sequence, and is discharged by the exhaust component 4. The waste gas treatment liquid 8 and the activated carbon adsorption plate 9 sequentially treat the pungent odor, thereby minimizing pollution to the factory environment and harm to the health of workers.

[0030] In the above, the enhancement component 5 is arranged between the suction component 1 and the lifting injection molding module 20, and increases the suction volume per unit time of the suction component 1 in the process of the lifting injection molding module 20 driving the injection mold 30 to open the mold; the enhancement component 5 specifically includes an suction piston 51 and a piston rod 52; wherein, the suction piston 51 is adapted to the suction chamber 11, the suction piston 51 is slidably arranged inside the suction chamber 11, the bottom end of the piston rod 52 is fixedly arranged on the top of the suction piston 51, the top end of the piston rod 52 is movable through the top of the suction chamber 11, and the top end of the piston rod 52 is fixedly arranged on the lifting injection molding module 20, so that the piston rod 52 is lifted and lowered with the lifting injection molding module 20 in the process of closing or opening the injection mold 30. When the injection mold 30 is opened, the piston rod 52 pulls the suction piston 51 to slide to the top position of the suction chamber 11. During this process, the effective space inside the suction chamber 11 (referring to the space connected to the suction port 12) increases, while the exhaust speed of the suction chamber 11 (depending on the exhaust volume of the exhaust component 4) remains unchanged, thereby forcing the suction volume of the suction port 12 per unit time to increase, so that more pungent odor enters the suction chamber 11 during the opening process of the injection mold 30, and is minimized from being emitted into the factory environment; when the injection mold 30 is closed, the piston rod 52 pushes the suction piston 51 to slide to the middle position of the suction chamber 11 (the height of the suction piston 51 always remains higher than the height of the suction port 12). At this time, although the effective space inside the suction chamber 11 is reduced, because the exhaust component 4 always remains in working condition, the pungent odor inside the suction chamber 11 will not be discharged again through the suction port 12, but will flow through the first processing box 2 and the second processing box 3 in sequence and then be discharged by the exhaust component 4. By increasing the air suction volume per unit time of the air suction component 1 during the process of opening the injection mold 30 , it is ensured that more pungent odors are collected by the air suction chamber 11 and transported to the next-level processing structure.

[0031] In this embodiment, a connecting pipe 13 is provided between the output end of the air intake component 1 and the input end of the first treatment box 2. The connecting pipe 13 is an L-shaped pipe structure. The top of the connecting pipe 13 is fixedly connected to the output end of the air intake component 1 (specifically, the bottom of the air intake chamber 11), and the bottom of the connecting pipe 13 is fixedly connected to the middle of the first treatment box 2. The bottom of the connecting pipe 13 is arranged tangentially to the first treatment box 2, so that the pungent odor enters the first treatment box 2 along the tangential direction, thereby forming an airflow impact on the waste gas treatment liquid 8; a vertically arranged central axis 21 is fixedly provided inside the first treatment box 2, and a stirring impeller 22 is rotatably provided on the outer periphery of the central axis 21 in a sleeve manner. An inclined dispersion net 23 is fixedly provided on the top of the stirring impeller 22, wherein the top of the central axis 21 is open, so that the stirring impeller 22 can be sleeved into the top of the central axis 21, and it is also convenient for the replacement or maintenance of the stirring impeller 22. By allowing the pungent odor to enter the first treatment box 2 in a tangential direction, an airflow impact is formed on the stirring impeller 22, so that the stirring impeller 22 drives the waste gas treatment liquid 8 to form a flow state inside the first treatment box 2. The stirring impeller 22 can stir the waste gas treatment liquid 8 to prevent the waste gas treatment liquid 8 from material precipitation and affecting the treatment efficiency of the pungent odor. The pungent odor needs to pass through the dispersion net 23 during the floating process. The dispersion net 23 disperses the bubbles of the pungent odor, thereby increasing the contact area between the pungent odor and the waste gas treatment liquid 8, thereby ensuring the treatment efficiency of the pungent odor.

[0032] A low-resistance component 7 is provided between the bottom of the stirring impeller 22 and the bottom of the first processing box 2 to reduce the rotational resistance of the stirring impeller 22; the low-resistance component 7 specifically includes multiple groups of fixed magnets 71 and multiple groups of movable magnets 72; wherein, the number of blades of the stirring impeller 22, the number of movable magnets 72, and the number of fixed magnets 71 are all provided in four groups, the four groups of movable magnets 72 are evenly fixedly provided at the bottom of the stirring impeller 22, and the four groups of fixed magnets 71 are evenly fixedly provided at the bottom of the first processing box 2, the four groups of fixed magnets 71 correspond one to one to the four groups of movable magnets 72 and are arranged to repel each other, so that the bottom of the stirring impeller 22 and the bottom of the first processing box 2 are kept spaced apart. By utilizing the repulsive relationship between the fixed magnet 71 and the movable magnet 72, a suspended design is formed between the stirring impeller 22 and the bottom of the first treatment box 2, thereby reducing the friction resistance between the two, which is beneficial to the rotation of the stirring impeller 22; in addition, during the rotation of the stirring impeller 22, the positional relationship between the fixed magnet 71 and the movable magnet 72 is continuously switched between mutual staggering and mutual overlap, so that the repulsive force between the fixed magnet 71 and the movable magnet 72 is continuously changed, so that the stirring impeller 22 and the dispersion net 23 can swing back and forth in the vertical direction, which is beneficial to the dispersion net 23 to disperse the bubbles of pungent odor, and is also beneficial to causing turbulence in the water flow of the waste gas treatment liquid 8 to prevent material precipitation in the waste gas treatment liquid 8 as much as possible.

[0033] In the above description, the spray assembly 6 is arranged between the first treatment box 2 and the lifting injection molding module 20, and the waste gas treatment liquid 8 is extracted to form a spraying state during the process of the lifting injection molding module 20 driving the injection mold 30 to close or open the mold. The spray assembly 6 specifically includes a water pumping box 61, a transfer box 62, a spray pipe 63, a transmission shaft 64, a water pumping piston 65, a transmission gear 66, a transmission rack 67, a compression piston 68 and a compression spring 69; wherein the water pumping box 61 is a hollow rectangular structure, the water pumping box 61 is fixedly arranged on the top of the first treatment box 2, the transfer box 62 is also a hollow rectangular structure, the transfer box 62 is fixedly arranged at the bottom of the water pumping box 61, and the bottom of the transfer box 62 is provided with a rotary water joint 6 in the prior art. 31, the spray pipe 63 is rotatably arranged at the bottom of the transfer box 62 through the rotating water joint 631, so that the spray pipe 63 can be rotated by force; the transmission shaft 64 is arranged horizontally, and the transmission shaft 64 is rotatably arranged in the water pumping box 61 through a preset sealed bearing, and the two ends of the transmission shaft 64 extend outward and rotate in sequence to pass through the first treatment box 2 and the connecting pipe 13, the water pumping piston 65 is threadedly connected to the transmission shaft 64, and the water pumping piston 65 is adapted to the water pumping box 61, so that the water pumping piston 65 is slidably arranged in the water pumping box Inside the box 61, the pumping box 61 is divided into two groups of pumping chambers 611; wherein, the bottom of the two groups of pumping chambers 611 and the bottom of the transfer box 62, and the top of the two groups of pumping chambers 611 and the bottom of the first treatment box 2 are connected with water flow pipes 612, and the middle position of the four groups of water flow pipes 612 are connected with a one-way valve 613 in the prior art. By setting the flow direction of the one-way valve 613, the waste gas treatment liquid 8 can only flow along the pumping box 61, the transfer box 62, the spray pipe in sequence. 63 direction of flow; the transmission gear 66 is located inside the connecting pipe 13 and is fixedly mounted on the transmission shaft 64. The top of the transmission rack 67 is fixedly mounted on the bottom of the suction piston 51. The bottom end of the transmission rack 67 extends into the inside of the connecting pipe 13 and is meshed with the transmission gear 66. The compression piston 68 is slidably mounted in the middle of the transfer box 62. The bottom end of the compression spring 69 is fixedly mounted on the top of the compression piston 68, and the top end of the compression spring 69 is fixedly mounted on the top of the transfer box 62. In addition, the transmission rack 67 is relatively long, and a limit slider can be provided to make the vertical movement of the transmission rack 67 more stable.

[0034] When the injection mold 30 is closed or opened, the piston rod 52 drives the suction piston 51 and the transmission rack 67 to rise or fall, thereby driving the transmission shaft 64 to rotate through the meshing of the gear rack, and then driving the water pumping piston 65 to move, so that the volume of the two sets of water pumping chambers 611 increases or decreases; when the volume of the water pumping chamber 611 increases, the waste gas treatment liquid 8 flows unidirectionally from the first treatment box 2 to the water pumping tank 61, and when the volume of the water pumping chamber 611 decreases, the waste gas treatment liquid 8 flows unidirectionally from the water pumping tank 61 to the transfer box 62, and the waste gas treatment liquid 8 compresses the compression spring 69 through the compression piston 68, so that the water pressure of the waste gas treatment liquid 8 inside the transfer box 62 increases, and finally is sprayed out through the spray pipe 63, forming a spray state inside the first treatment box 2, further increasing the contact area between the pungent odor and the waste gas treatment liquid 8, and ensuring the treatment efficiency of the pungent odor.

One side of the four groups of spray pipes 63 is provided with spray holes 632 arranged tilted downward. In the process of the waste gas treatment liquid 8 being sprayed out from the spray holes 632, a reaction force will be generated on the spray pipes 63, thereby pushing the spray pipes 63 to rotate, so that the waste gas treatment liquid 8 is sprayed more evenly inside the first treatment box 2, further increasing the contact area between the pungent odor and the waste gas treatment liquid 8, and ensuring the treatment efficiency of the pungent odor.

[0037] In this embodiment, two groups of air suction components 1 are configured, and the two groups of air suction components 1 are respectively located on the two sides of the lower mold; accordingly, the reinforcement component 5, the connecting pipe 13, the transmission gear 66, the transmission rack 67 and other structures are also configured in two groups, so that the structure of the odor removal module 40 is more stable.

[0038] Implementation principle:

[0039] When the injection mold 30 is closed or opened, the piston rod 52 drives the suction piston 51 and the transmission rack 67 to rise or fall, thereby driving the transmission shaft 64 to rotate through the meshing of the gear rack, and then driving the water pumping piston 65 to move, so that the volume of the two sets of water pumping chambers 611 increases or decreases; when the volume of the water pumping chamber 611 increases, the waste gas treatment liquid 8 flows unidirectionally from the first treatment box 2 to the water pumping tank 61, and when the volume of the water pumping chamber 611 decreases, the waste gas treatment liquid 8 flows unidirectionally from the water pumping tank 61 to the transfer box 62, and the waste gas treatment liquid 8 compresses the compression spring 69 through the compression piston 68, so that the water pressure of the waste gas treatment liquid 8 inside the transfer box 62 increases, and finally is sprayed out through the spray pipe 63, forming a spray state inside the first treatment box 2, further increasing the contact area between the pungent odor and the waste gas treatment liquid 8, and ensuring the treatment efficiency of the pungent odor.

[0040] When the injection mold 30 is opened, the piston rod 52 pulls the suction piston 51 to slide to the top position of the suction chamber 11. During this process, the effective space inside the suction chamber 11 (referring to the space connected to the suction port 12) increases, while the exhaust speed of the suction chamber 11 (depending on the exhaust volume of the exhaust component 4) remains unchanged, thereby forcing the suction volume of the suction port 12 per unit time to increase, so that more pungent odor enters the suction chamber 11 during the opening process of the injection mold 30, and is minimized from being emitted into the factory environment; when the injection mold 30 is closed, the piston rod 52 pushes the suction piston 51 to slide to the middle position of the suction chamber 11 (the height of the suction piston 51 always remains higher than the height of the suction port 12). At this time, although the effective space inside the suction chamber 11 is reduced, because the exhaust component 4 always remains in working condition, the pungent odor inside the suction chamber 11 will not be discharged again through the suction port 12, but will flow through the first processing box 2 and the second processing box 3 in sequence and then be discharged by the exhaust component 4. By increasing the air suction volume per unit time of the air suction component 1 during the process of opening the injection mold 30 , it is ensured that more pungent odors are collected by the air suction chamber 11 and transported to the next-level processing structure.

[0041] The embodiments of this specific implementation method are all preferred embodiments of the present application and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be covered within the scope of protection of the present application.
