Description

Technical Field

[0002] Injection molding machine, also known as injection molding machine or injection machine, is the main molding equipment for thermoplastic plastics or thermosetting plastics using plastic molding molds to make plastic products of various shapes. Injection molding is achieved through injection molding machines and molds, which are divided into vertical, horizontal, and all-electric types. When the injection molding machine is working, first add granular or powdered plastics into the barrel, and make the plastic molten by rotating the screw and heating the outer wall of the barrel, and then inject the plasticized molten plastic into the closed mold cavity, and form the required products after cooling and solidification. However, when the equipment is demolded after injection molding, the molded workpiece is prone to collision and damage, thereby reducing the quality of the molded workpiece. It is not easy to control the demolding angle of the molded workpiece during demolding, so that the workpiece needs to be manually picked up after demolding, which affects the unloading of the workpiece after molding. It is not easy to protect the injection molding position when the equipment is performing injection molding, so that the equipment has deviations during mold closing, resulting in incomplete injection molding, reducing the sealing of the equipment during mold closing, and causing the activity space to affect the adjustment of the workpiece when the equipment is separated.

It is not easy to control the demoulding angle of the molded workpiece during demoulding.

[0024] The present invention provides a multi-directional flip demoulding injection molding machine and an injection molding process, which have the following beneficial effects:

[0025] 1. The multi-directional flip demolding injection molding machine and injection molding process are provided with an upper mold base, an injection molding tube, and a connecting frame. The upper mold base is supported by the connecting frame under the drive of a lifting cylinder to ensure that the connection position between the connecting frame and the upper mold base is not easy to loosen, so that the connecting frame can protect the upper mold base and the upper mold base can move smoothly. The injection molding tube connects the upper mold base and the frame, so that the injection molding tube can be extended and retracted with the lifting and lowering of the upper mold base, thereby adjusting the length of the injection molding tube, making it difficult for the injection molding tube to leak when the molten raw material flows, thereby ensuring the sealing of the injection molding tube when the molten raw material flows. The flip component can rotate inside the frame, so that the flip component rotates the workpiece molding position to adjust the demolding direction of the molded workpiece.

[0026] 2. The multi-directional flip demoulding injection molding machine and the injection molding process support the protective shell on the frame through the bracket, so that the protective shell is kept horizontal on the bracket, avoiding the loosening of the connection position between the protective shell and the bracket to affect the fixation, thereby improving the stability of the bracket inside the frame. The transmission gear rotates under the drive of the adjustment motor, so that the transmission gear drives the transmission sleeve to rotate, which is convenient for the transmission sleeve to rotate the lower mold base through the side support frame, avoiding the deformation of the position where the protective shell is connected to the transmission sleeve and causing damage.

[0027] 3. The multi-directional flip demoulding injection molding machine and injection molding process support the lower mold base on the transmission sleeve through the side support frame, ensuring that there is no gap at the molding position when the upper mold base contacts the lower mold base, which is convenient for the lower mold base to support each other when contacting the upper mold base. The rotating shaft is driven by the rotating motor on the lower mold base to rotate, so that when the lower mold base rotates, the side support frame and the rotating shaft cooperate to reinforce it, ensuring that the lower mold base rotates to adjust the demoulding angle of the workpiece, so that the lower mold base can be demoulded at different angles.

[0028] 4. The multi-directional flip demoulding injection molding machine and injection molding process, through the pressure of the mounting plate, drives the reset push rod to move along the lower mold base to push the workpiece, so that the workpiece is easy to fall off from the inside of the lower mold base, thereby enhancing the strength of the lower mold base itself, and the position of the lap plate can limit the fixed ring, so that the lap plate and the fixed ring and the inner support block cooperate to support each other, so that the inner support block can keep horizontal under the support of the lap plate, thereby ensuring the activity space of the fixed ring and the inner support block of the lower mold base.

[0029] 5. The multi-directional flip demoulding injection molding machine and the injection molding process limit the range of workpiece receiving inside the frame by means of the assembly frame, so that the assembly frame can increase the contact area inside the frame, and facilitate the assembly frame and the frame to separate different activity spaces. The receiving seat corresponds to the lower mold seat on the telescopic rod, and the receiving seat receives the workpiece dropped from the lower mold seat, so that the receiving seat places the workpiece, ensuring that the receiving seat remains horizontal on the telescopic rod, and preventing the workpiece from falling off the receiving seat.

[0030] 6. The multi-directional flip demoulding injection molding machine and the injection molding process separate the installation position of the telescopic rod on the receiving seat through the air supply tube, so that the installation position of the air supply tube can be used to position the telescopic rod, ensuring that the workpiece is not easily burned when it is taken out from the inside of the receiving seat, and a spring is provided between the buffer plate and the receiving seat, so that when the buffer plate loses pressure, the spring resets and pushes the buffer plate to rise and reset, so that the buffer of the buffer plate can protect the receiving seat and prevent the buffer plate from tilting when it is lifted and lowered on the receiving seat.

[0031] 7. The multi-directional flip demoulding injection molding machine and injection molding process are provided with two clamping plates on the docking shell to prevent the position where the clamping plates are installed on the docking shell from being hit and falling off the assembly frame. The middle fixing plate limits the screw inside the docking shell, so that the middle fixing plate can limit the rotation and reset of the screw, which is convenient for the screw to be installed vertically on the middle fixing plate, thereby ensuring the fixing effect of the middle fixing plate on the screw and avoiding the problem of slipping or tilting during the lifting and lowering of the screw.

[0032] 8. The multi-directional flip demoulding injection molding machine and the injection molding process connect the screw and the docking shell through the support block, so that the support block can reinforce different positions of the docking shell to prevent the docking shell from being deformed and causing the movement of the support block to be stuck. The purifier slides along the docking shell driven by the support block, so that the purifier purifies the air inside the docking shell and the frame, avoiding the generation of odor when the workpiece is injected into the frame, and ensuring that the purifier can fully perform purification work inside the docking shell.

[0033] 9. The multi-directional flip demoulding injection molding machine and injection molding process are installed on the frame through the ventilation shell, which is convenient for wind to circulate inside the ventilation shell, so as to filter the wind force when using the ventilation shell flow, thereby reducing the dust accumulated inside the ventilation shell. The inner support frame can support the ventilation shell, which is convenient for maintaining the activity space inside the ventilation shell, so that the installation position of the ventilation shell on the frame is not easily affected, ensuring the stability of the cold air duct when working, and allowing the wind force inside the ventilation shell to be transported to the air guide shell.

[0034] 10. The multi-directional flip demoulding injection molding machine and injection molding process guide the delivered cold air on the cold air duct through a guide frame, so that the guide frame can disperse the wind force delivered by the cold air duct, and then use the ventilation shell to protect the cold air duct. The movable plate is rotated inside the guide frame by the cold air circulation, so that the rotation of the movable plate can guide the circulation of the cold air, and the rotation of the movable plate can disturb the circulation of the cold air, thereby increasing the bearing capacity of the guide frame itself.

The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0049] Example 1, please refer to Figure 1-Figure 12 The present invention provides a technical solution: a multi-directional flip demolding injection molding machine, comprising a frame 1, a lifting cylinder 2 is fixedly connected to the top of the frame 1, and the lifting cylinder 2 extends on the frame 1 to drive the connecting frame 8 to descend, so that the connecting frame 8 descends and drives the upper mold base 7 to descend, and vice versa, the lifting cylinder 2 contracts to drive the connecting frame 8 to rise, so that the lifting cylinder 2 is extended and retracted to adjust the position of the upper mold base 7, ensuring that the upper mold base 7 is lifted and lowered in the vertical direction, thereby ensuring the accuracy of the movement of the upper mold base 7, avoiding the situation of inaccurate positioning when the lifting cylinder 2 is extended and retracted, and ensuring the sealing effect during subsequent injection molding, and also includes:

[0050] The connecting frame 8 is fixedly connected to the bottom end of the lifting cylinder 2. The upper mold base 7 is supported by the connecting frame 8 under the drive of the lifting cylinder 2, so that the connecting frame 8 fixes the upper mold base 7, ensuring that the connection position between the connecting frame 8 and the upper mold base 7 is not easy to loosen, so that the connecting frame 8 can protect the upper mold base 7, so that the upper mold base 7 can move smoothly, and the activity space between the connecting frame 8 and the upper mold base 7 can be used for injection molding of the molten material, so as to avoid the change of the activity space between the connecting frame 8 and the upper mold base 7 and cause the injection tube 3 to be damaged. The top of the connecting frame 8 is fixedly connected with a limiting ring 9, and the limiting ring 9 contacts the lifting cylinder 2 on the connecting frame 8, so that the limiting ring 9 and the connecting frame 8 cooperate to reinforce the lifting cylinder 2 to prevent the connection position between the lifting cylinder 2 and the connecting frame 8 from being loose, so that the limiting ring 9 and the connecting frame 8 cooperate to increase the contact area, so that the limiting ring 9 and the connecting frame 8 support each other, and the contact position between the limiting ring 9 and the lifting cylinder 2 can limit the contraction distance of the lifting cylinder 2, so that the lifting cylinder 2 can be extended and retracted on the frame 1. It is not easy to get stuck, which improves the convenience of the lifting cylinder 2 to perform telescopic movement. The bottom of the connecting frame 8 is fixedly connected to the upper mold base 7. The bottom of the upper mold base 7 has a protrusion, so that the upper mold base 7 is inserted into the inside of the flip component 4 when it drops to contact the flip component 4, so that the upper mold base 7 is sealed when connected to the flip component 4, so that the upper mold base 7 is not easy to tilt when performing lifting movement, ensuring the sealing of the contact position between the upper mold base 7 and the flip component 4, so that the upper mold base 7 and the flip component 4 form a molding cavity to mold the workpiece, and the upper mold base 7 The top of the frame 1 is fixedly connected with an injection molding tube 3, and the upper mold base 7 and the frame 1 are connected through the injection molding tube 3, so that the injection molding tube 3 can be extended and retracted with the lifting and lowering of the upper mold base 7, thereby adjusting the length of the injection molding tube 3, so that the injection molding tube 3 is not easy to leak when the molten raw material flows, thereby ensuring the sealing of the injection molding tube 3 when the molten raw material flows, and the installation position of the injection molding tube 3 on the frame 1 cooperates with the lifting cylinder 2 to limit the lifting position of the upper mold base 7, thereby avoiding the upper mold base 7 from deflecting when it descends to contact the flip assembly 4;

[0051] The flip assembly 4 is fixedly connected to the inner surface of the frame 1. The flip assembly 4 is used to flip the workpiece after injection molding and take out the workpiece after mold closing. The flip assembly 4 can be rotated inside the frame 1, so that the flip assembly 4 rotates the workpiece molding position to adjust the demoulding direction of the molded workpiece, so that the flip assembly 4 can adjust different angles for demoulding according to needs, so that the workpiece can be collected after falling from the flip assembly 4 to prevent damage to the workpiece during demoulding. The flip assembly 4 can play a supporting role when connected to the frame 1, so that the flip assembly 4 is used to reinforce the frame 1, avoiding the problem of the flip assembly 4 falling off or tilting on the frame 1;

[0052] The blowing assembly 6 is fixedly connected to the position of the frame 1 away from the flip assembly 4. The blowing assembly 6 is used to deliver cold air to the position of the formed workpiece. The blowing assembly 6 can blow cold air to the position where the workpiece appears in the flip assembly 4 on the frame 1, so that the formed workpiece is cooled when the cold air contacts the workpiece, which is convenient for the subsequent workpiece to be taken out from the flip assembly 4, thereby ensuring the integrity of the workpiece when the flip assembly 4 takes out the workpiece. The blowing assembly 6 blows the cold air from obliquely above, so that the ventilation inside the frame 1 can be accelerated when the cold air circulates, thereby preventing the flip assembly 4 from maintaining a high temperature for a long time and affecting the forming of the workpiece;

[0053] The receiving assembly 5 is fixedly connected to the bottom of the inner cavity of the frame 1. The receiving assembly 5 is used to receive the workpiece dropped by the flip assembly 4. The receiving assembly 5 is located below the flip assembly 4, so that the receiving assembly 5 can receive the workpiece dropped by the flip assembly 4, so that the receiving assembly 5 can cool down the workpiece again when receiving the workpiece, thereby ensuring that the workpiece is cooled thoroughly and preventing the workpiece from being damaged when receiving the workpiece. When the wind blown by the receiving assembly 5 flows to the position where the workpiece drops from the flip assembly 4, the flip assembly 4 can be cleaned, thereby reducing the debris remaining inside the flip assembly 4;

[0054] The flip assembly 4 includes a bracket 41, which is fixedly connected to the inner surface of the frame 1. The protective shell 42 is supported on the frame 1 by the bracket 41, so that the protective shell 42 remains horizontal on the bracket 41, which is convenient for the bracket 41 to reinforce the protective shell 42, thereby avoiding the loosening of the connection position between the protective shell 42 and the bracket 41 and affecting the fixation. The bracket 41 and the protective shell 42 cooperate to separate the frame 1, so that the installation position of the docking assembly 5 is protected, thereby avoiding the installation position of the docking assembly 5 being affected, thereby improving the stability of the bracket 41 inside the frame 1. The top of the bracket 41 is fixedly connected with the protective shell 42, and the protective shell 4 2 is rotatably connected with a transmission gear 43 at the bottom of the inner cavity. The transmission gear 43 is driven by the adjusting motor to rotate, so that the transmission gear 43 drives the transmission sleeve 46 to rotate, so that the transmission sleeve 46 rotates to rotate the lower die seat 45 through the side support frame 44, so that the transmission sleeve 46 rotates to adjust the angle of the lower die seat 45, thereby adjusting the contact area between the upper die seat 7 and the lower die seat 45. The position where the transmission gear 43 and the transmission sleeve 46 contact the protective shell 42 can increase the bearing force of the protective shell 42, avoiding the deformation of the position where the protective shell 42 is connected to the transmission sleeve 46 and causing damage. The outer surface of the transmission gear 43 is meshedly connected with the transmission sleeve 46;

[0055] The side support frame 44 is fixedly connected to the inner surface of the transmission sleeve 46, and the lower die seat 45 is supported on the transmission sleeve 46 by the side support frame 44, so that the lower die seat 45 corresponds to the upper die seat 7 inside the transmission sleeve 46, ensuring that when the upper die seat 7 and the lower die seat 45 are in contact, it is not easy to have a gap at the molding position, which is convenient for the lower die seat 45 to support each other when contacting the upper die seat 7. The support of the lower die seat 45 by the side support frame 44 can maintain the activity space inside the transmission sleeve 46 for the rotation of the lower die seat 45, so that the lower die seat 45 is not easy to collide with the transmission sleeve 46 when rotating, ensuring the convenience of the lower die seat 45 rotating inside the transmission sleeve 46, and the side support frame 44 is far A lower die base 45 is fixedly connected to one side away from the transmission sleeve 46, and a rotating shaft 47 is fixedly connected to one side of the lower die base 45 away from the side support frame 44. The rotating shaft 47 is driven by a rotating motor to rotate on the lower die base 45, so that when the lower die base 45 rotates, the side support frame 44 cooperates with the rotating shaft 47 to reinforce it, ensuring that the lower die base 45 rotates to adjust the demoulding angle of the workpiece, so that the lower die base 45 can be demoulded at different angles. The rotating shaft 47 cooperates with the side support frame 44 to support the lower die base 45 from different positions, thereby increasing the bearing capacity of the lower die base 45 and ensuring that the lower die base 45 remains level inside the transmission sleeve 46.

[0056] The bottom of the transmission sleeve 46 is rotatably connected to the protective shell 42 , and the top of the transmission sleeve 46 extends to the outside of the protective shell 42 .

[0057] The inner surface of the limiting ring 9 is fixedly connected to the lifting cylinder 2 , and the outer surface of the injection tube 3 is fixedly connected to the frame 1 .

[0058] Among them, a reset push rod 49 is slidably connected to the inner surface of the lower die seat 45, and a mounting plate 410 is fixedly connected to the bottom end of the reset push rod 49. The mounting plate 410 is pressed to drive the reset push rod 49 to move along the lower die seat 45 to push the workpiece, so that multiple reset push rods 49 squeeze the workpiece from different positions, which is convenient for the workpiece to fall off from the lower die seat 45. When the spring on the reset push rod 49 loses pressure, the reset push rod 49 pushes the mounting plate 410 to reset, so that a movable space is generated between the lower die seat 45 and the mounting plate 410, ensuring that the reset push rod 49 can slide conveniently inside the lower die seat 45, and preventing the reset push rod 49 from getting stuck when moving on the lower die seat 45.

[0059] The fixing ring 411 is fixedly connected to the bottom of the inner cavity of the lower die base 45. The fixing ring 411 cooperates with the inner support block 48 inside the lower die base 45 to reinforce different positions inside the lower die base 45, thereby enhancing the strength of the lower die base 45 itself. The inner support blocks 48 are evenly distributed on the fixing ring 411, so that the position where the inner support block 48 connects to the lower die base 45 limits the installation position of the fixing ring 411, avoiding the displacement of the fixing ring 411 inside the lower die base 45, so that the inner support block 48 protects the installation position of the fixing ring 411. The top of the fixing ring 411 is fixedly connected with the inner support block 48, and the bottom of the inner support block 48 is fixedly connected to the inner support block 48. A lap plate 412 is fixedly connected, and two lap plates 412 are arranged on the inner support block 48, so that the lap plate 412 supports the inner support block 48 when it is connected to the lower mold base 45, thereby increasing the firmness of the position of the inner support block 48 connected to the lower mold base 45, and the position of the lap plate 412 can limit the fixed ring 411, so that the lap plate 412, the fixed ring 411 and the inner support block 48 cooperate to support each other, so that the inner support block 48 remains horizontal under the support of the lap plate 412, thereby ensuring the movable space between the fixing ring 411 and the inner support block 48 of the lower mold base 45, and the side of the inner support block 48 away from the fixing ring 411 is fixedly connected to the lower mold base 45.

[0060] The bottom of the lap plate 412 is fixedly connected to the lower die base 45 , and both ends of the reset push rod 49 pass through the lower die base 45 .

[0061] The receiving assembly 5 includes an assembly frame 51, which is fixedly connected to the bottom of the inner cavity of the frame 1. The range of receiving the workpiece is limited inside the frame 1 by the assembly frame 51, so that the falling position of the workpiece is protected by the assembly frame 51, so that the assembly frame 51 can increase the contact area inside the frame 1, which is convenient for the assembly frame 51 and the frame 1 to separate different activity spaces. The installation position of the assembly frame 51 corresponds to the bracket 41, so that the docking shell 55 installed on the assembly frame 51 cooperates with each other, and the docking shell 55 is used to reinforce the assembly frame 51 while limiting the activity space inside the assembly frame 51. The receiving seat 52 corresponds to the lower mold seat 45 on the telescopic rod 54. The inner surface of the assembly frame 51 is fixedly connected with the docking shell 55, and the bottom of the inner cavity of the assembly frame 51 is fixedly connected with the telescopic rod 54.

[0062] The receiving seat 52 is fixedly connected to the top of the telescopic rod 54. The receiving seat 52 is used to receive the formed workpiece. The workpiece dropped from the lower die seat 45 is received by the receiving seat 52, so that the receiving seat 52 places the workpiece, and the receiving seat 52 is pressed down by the pressure of the lower die seat 45, so that the receiving seat 52 is pressed down to squeeze the telescopic rod 54, so that the telescopic rod 54 can be extended to support the receiving seat 52, ensuring that the receiving seat 52 remains horizontal on the telescopic rod 54. When the receiving seat 52 loses pressure, the telescopic rod 54 is lifted. 54 extends and pushes the receiving seat 52 upward, so that the receiving seat 52 cooperates with the lower die seat 45 to limit the receiving of the workpiece, thereby preventing the workpiece from falling off the receiving seat 52. The inner surface of the receiving seat 52 is slidably connected with a buffer plate 53, and the buffer plate 53 is pressed down by the lower die seat 45 on the receiving seat 52, so that the buffer plate 53 moves toward the inside of the receiving seat 52 to buffer the pressure on the lower die seat 45, thereby preventing the lower die seat 45 from contacting the receiving seat 52 and colliding to cause damage, and the buffer plate 53 and the receiving seat 52 are connected. A spring is provided between the two sides, so that the buffer plate 53 is lowered to squeeze the spring, so that when the buffer plate 53 loses pressure, the spring resets and pushes the buffer plate 53 to rise and reset, so that the buffer of the buffer plate 53 can protect the docking seat 52 and prevent the buffer plate 53 from tilting when it is lifted and lowered on the docking seat 52. A shunt pipe rack 56 is fixedly connected to the bottom of the inner cavity of the docking seat 52, and the bottom of the shunt pipe rack 56 is connected to an air supply tube 57, and the installation position of the telescopic rod 54 on the docking seat 52 is controlled by the air supply tube 57. The separation makes it convenient to position the telescopic rod 54 at the installation position of the air supply tube 57, so that the wind generated by the air supply tube 57 can be transmitted to the inside of the shunt pipe rack 56, so that the shunt pipe rack 56 can discharge wind from different positions of the receiving seat 52 to cool the workpiece, ensuring that the workpiece is not easily burned when it is taken out from the inside of the receiving seat 52.

The snap-on plates 511 can also increase the bearing capacity of the docking shell 55 itself, thereby ensuring the activity space inside the docking shell 55, facilitating the air circulation of the docking shell 55, and thus improving the firmness of the installation position of the docking shell 55, ensuring the integrity of the docking shell 55 and the snap-on plates 511. The bottom of the inner cavity of the docking shell 55 is fixedly connected with The middle fixing plate 510 limits the screw 59 inside the docking shell 55 through the middle fixing plate 510, so that the middle fixing plate 510 can limit the rotation and reset of the screw 59, so that the screw 59 can be installed vertically on the middle fixing plate 510. The screw 59 is driven by the lifting motor to rotate clockwise, so that the screw 59 rotates clockwise and rises on the middle fixing plate 510, and vice versa, the screw 59 rotates counterclockwise and descends on the middle fixing plate 510, so that the screw 59 moves to adjust the position of the support block 58, thereby ensuring the fixing effect of the middle fixing plate 510 on the screw 59, and avoiding the problem of slipping or tilting of the screw 59 during the lifting process;

[0065] The screw 59 is rotatably connected to the inner surface of the middle fixing plate 510. The top of the screw 59 is rotatably connected to the support block 58.

[0066] The two ends of the screw rod 59 extend to the outside of the middle fixing plate 510 , and the outer surface of the support block 58 is slidably connected to the docking shell 55 .

[0067] Wherein, the blowing assembly 6 includes a ventilation shell 61, which is fixedly connected to the inner surface of the frame 1. The ventilation shell 61 is used to circulate air. The ventilation shell 61 is installed on the frame 1, so that the cold air tube 64 inside the ventilation shell 61 works to guide the outside air into the ventilation shell 61, so that the wind can circulate inside the ventilation shell 61, so that the ventilation shell 61 is used to filter the wind when the wind is flowing, thereby reducing the dust accumulated inside the ventilation shell 61, and the air guide shell 66 on the ventilation shell 61 can limit the blowing of the wind, so that the air guide shell 66 can transport the wind to the position of the lower mold base 45 to cool the workpiece, thereby accelerating the cooling speed of the workpiece. The outer surface of the ventilation shell 61 passes through the frame 1, and the side of the ventilation shell 61 close to the connecting frame 8 is connected to the air guide shell 66;

[0068] The inner support frame 62 is fixedly connected to the top of the inner cavity of the ventilation shell 61. The ventilation shell 61 can be supported by the inner support frame 62, which is convenient for maintaining the movable space inside the ventilation shell 61, so that the installation position of the ventilation shell 61 on the frame 1 is not easily affected, and the inner support frame 62 can fix the cold air tube 64, so that the cold air tube 64 is not easy to loosen on the inner support frame 62, ensuring the stability of the cold air tube 64 when working, so that the inner support frame 62 fixes the cold air tube 64 to correspond to the air guide shell 66, so that the wind force inside the ventilation shell 61 is transported to the air guide shell 66, the inner surface of the inner support frame 62 is fixedly connected with the cold air tube 64, and one end of the cold air tube 64 close to the air guide shell 66 is connected to the guide frame 63, and the cold air transported is guided on the cold air tube 64 by the guide frame 63, so that the cold air is transported to the air guide shell 66 in the guide frame 63, The installation position of the guide frame 63 is restricted by the cold air duct 64, ensuring that the guide frame 63 is suspended, so that the guide frame 63 can disperse the wind force delivered by the cold air duct 64, ensuring that the wind force delivered by the guide frame 63 can cool down the inside of the ventilation shell 61 together, and then use the ventilation shell 61 to protect the cold air duct 64. The inner surface of the guide frame 63 is rotatably connected with a movable plate 65, and the movable plate 65 is rotated by the cold air flow inside the guide frame 63, so that the rotation of the movable plate 65 can guide the circulation of the cold air, and the rotation of the movable plate 65 can disturb the circulation of the cold air. The guide frame 63 is reinforced by two movable plates 65, thereby increasing the bearing capacity of the guide frame 63 itself, making it difficult for the movable plate 65 to fall when rotating inside the guide frame 63, ensuring that the rotation of the movable plate 65 promotes the circulation of cold air.

[0069] Example 2, please refer to Figure 1-Figure 12On the basis of Example 1, the present invention provides a technical solution: an injection molding process of a multi-directional flip demolding injection molding machine, step 1: the lifting cylinder 2 is extended on the frame 1 to push the connecting frame 8 down, so that the connecting frame 8 drives the upper mold base 7 to descend and stops when it contacts the lower mold base 45, and the injection tube 3 is extended on the frame 1 when the connecting frame 8 descends, and the molten raw material is transported to the upper mold base 7 and the lower mold base 45 through the injection tube 3 to generate an injection cavity for injection molding of the workpiece, and after the casting is completed, the lifting cylinder 2 is contracted to drive the connecting frame 8 to rise, so that the connecting frame 8 drives the upper mold base 7 to separate from the lower mold base 45, and the injection tube 3 is contracted as the connecting frame 8 rises;

[0070] Step 2: The cold air cylinder 64 inside the ventilation shell 61 generates wind force, so that the outside air enters the ventilation shell 61. The ventilation shell 61 can filter the air when circulating the air, and the inner support frame 62 fixes the installation position of the cold air cylinder 64. As the cold air generated by the cold air cylinder 64 is transported to the inside of the guide frame 63, the movable plate 65 is driven by the cold air to rotate and guide the cold air into the air guide shell 66, so that the cold air discharged from the air guide shell 66 is blown to the position of the lower mold base 45, so that the cold air cools the workpiece inside the lower mold base 45;

[0071] Step 3: When the lower die base 45 is blown by cold wind and separated from the upper die base 7, the transmission gear 43 rotates under the drive of the adjustment motor, so that the transmission gear 43 drives the transmission sleeve 46 to rotate on the protective shell 42, and the transmission sleeve 46 rotates to drive the lower die base 45 to rotate through the side support frame 44, so that the lower die base 45 rotates to adjust the formed workpiece, and the bracket 41 supports the protective shell 42 on the frame 1, and as the rotating motor rotates on the transmission sleeve 46, it drives the rotating shaft 47 to rotate, so that the rotating shaft 47 drives the lower die base 45 to rotate on the side support frame 44 to flip the lower die base 45, so that the rotation of the rotating shaft 47 and the transmission sleeve 46 cooperates with each other to achieve the purpose of multi-directional flipping of the lower die base 45, and the lower die base 45 rotates until the workpiece faces the receiving seat 52 and stops;

[0072] Step 4: Using the pressure of the mounting plate 410 to drive the reset push rod 49 to apply a thrust to the workpiece, so that the workpiece falls from the inside of the lower die seat 45 to the receiving seat 52, the inner support block 48 supports the lower die seat 45 on the fixing ring 411, and two lap plates 412 are set on the inner support block 48, so that the lap plates 412 contact the lower die seat 45 to fix the inner support block 48, after the workpiece falls, the rotating motor drives the rotating shaft 47 to continue rotating, so that the rotating shaft 47 drives the lower die seat 45 to rotate and reset and then stop, at this time, the lower die seat 45 corresponds to the upper die seat 7;

[0073] Step 5: When the lower die base 45 rotates, it contacts the buffer plate 53, so that the buffer plate 53 is pressed by the lower die base 45 and slides toward the inside of the receiving seat 52. When the lower die base 45 contacts the receiving seat 52, it pushes the receiving seat 52 downward, so that the receiving seat 52 drives the telescopic rod 54 to contract, so that the receiving seat 52 and the lower die base 45 correspond to each other to receive the workpiece. After the lower die base 45 is reset, the buffer plate 53 loses pressure and resets, and the telescopic rod 54 extends to push the receiving seat 52 back to the initial position. The air supply tube 57 delivers wind to the inside of the shunt pipe rack 56 on the receiving seat 52, so that the shunt pipe rack 56 blows the workpiece received by the receiving seat 52 to reduce the temperature of the workpiece.

[0074] Step 6: Use the clamping plate 511 to protect the docking shell 55, and the screw 59 is driven by the lifting motor to rotate clockwise, so that the screw 59 rotates clockwise to drive the support block 58 to rise along the docking shell 55, so that the support block 58 pushes the purifier 512 to move. Conversely, the screw 59 rotates counterclockwise to drive the support block 58 to descend, so that the lifting of the support block 58 adjusts the position of the purifier 512 inside the docking shell 55. When the purifier 512 starts, the air inside the docking shell 55 and the frame 1 is purified.
