[0031] In the current oblique-mouth blow molding machine, the hole axis of the blowing hole is inclined relative to the first axis. When blowing, the airflow exerts a pushing force on the mold-moving mechanism 400. The pushing force has a component force in the direction of the first axis, which may push the mold-moving mechanism 400 to loosen along the first axis and move away from the blowing mechanism 300, affecting the blow molding quality of the product.
[0032] Reference Figures 1 to 2, is a slant-mouth blow molding machine according to an embodiment of the present invention, comprising a machine base 100, a preform loading mechanism 200, an air blowing mechanism 300, a mold shifting mechanism 400, a mold shifting driver and a locking mechanism 500. The machine base 100 is provided with an embryo loading station 110 and a blow molding station 120 arranged along the first axis direction; the embryo loading mechanism 200 is provided on the machine base 100 and is located at the embryo loading station 110; the blowing mechanism 300 is provided on the machine base 100 and is located at the blow molding station 120, and the blowing mechanism 300 is provided with a blowing hole, and the hole axis of the blowing hole is inclined relative to the first axis; the mold shifting mechanism 400 is movably provided on the machine base 100 along the first axis direction and can be switched between the embryo loading station 110 and the blow molding station 120, and the mold shifting mechanism 400 is provided with a mold mounting position; the mold shifting driver is provided on the machine base 100 and is used to drive the mold shifting mechanism 400 to move; the locking mechanism 500 is provided between the machine base 100 and the mold shifting mechanism 400, and when the mold shifting mechanism 400 is at the blow molding station 120, the locking mechanism 500 can lock or unlock the position of the mold shifting mechanism 400 relative to the machine base 100.
[0033] During production of the oblique-mouth blow molding machine, the mold moving driver moves the mold moving mechanism 400 to the embryo loading station 110, receives the embryo from the embryo loading mechanism 200, and then the mold moving driver moves the mold moving mechanism 400 to the blow molding station 120, and the locking mechanism 500 locks the position of the mold moving mechanism 400, and then the blowing mechanism 300 blows the blow mold on the mold moving mechanism 400 through the blowing hole. After the blow molding is completed, the locking mechanism 500 unlocks the position of the mold moving mechanism 400, making it convenient for the mold moving mechanism 400 to move back to the embryo loading station 110 to receive a new embryo; by adding the locking mechanism 500, the locking mechanism 500 can lock the position of the mold moving mechanism 400 when the blowing mechanism 300 blows, thereby reducing the risk of the airflow pushing the mold moving mechanism 400 to loosen along the first axis away from the blowing mechanism 300, thereby improving the blow molding quality of the product.
[0034] In an embodiment, the locking mechanism 500 includes a first locking hook 510, a second locking hook 520 and a locking hook driver 530. The first locking hook 510 is arranged on the mold shifting mechanism 400, and the second locking hook 520 is movably arranged on the machine base 100. The locking hook driver 530 is arranged on the machine base 100 and can drive the second locking hook 520 to move. When the mold shifting mechanism 400 is at the blow molding station 120, the locking hook driver 530 can drive the second locking hook 520 to move to a position connected or disconnected with the first locking hook 510. When the mold shifting mechanism 400 moves to the blow molding station 120, the locking hook driver 530 drives the second locking hook 520 to move to connect with the first locking hook 510. At this time, the machine base 100 locks and limits the position of the mold shifting mechanism 400 through the second locking hook 520 and the first locking hook 510. At this time, even if the blowing mechanism 300 blows air into the blow molding mold, the mold shifting mechanism 400 is not easy to loosen relative to the machine base 100 and move away from the blowing mechanism 300, which is conducive to the mold shifting mechanism 400 maintaining its position; when the blowing mechanism 300 completes blow molding, the locking hook driver 530 can drive the second locking hook 520 to move to disengage from the first locking hook 510, thereby allowing the mold shifting mechanism 400 to move to the embryo loading station 110.
[0035] In this embodiment, the hook actuator 530 is provided with a telescopic portion, and the second hook 520 is connected to the telescopic portion and moves synchronously with the telescopic portion. The telescopic direction of the second hook 520 is parallel to the axis of the blowhole. Specifically, the hook actuator 530 is a hydraulic cylinder, and the telescopic portion is a cylinder rod. The second hook 520 is mounted on the cylinder rod. The hydraulic cylinder drives the second hook 520 to connect and disconnect with the first hook 510. When the first hook 510 and the second hook 520 are connected, they have good stability and can apply a large force to the mold shifting mechanism 400 to maintain the position of the mold shifting mechanism 400. It is conceivable that in other embodiments, the hook actuator 530 can also be other types of hydraulic cylinders, or use a pneumatic cylinder, an electric cylinder, etc., and those skilled in the art can configure it according to actual needs.
[0036] In an embodiment, the locking hook driver 530 includes a hydraulic cylinder, a liquid inlet valve, and a liquid outlet valve. The hydraulic cylinder has a liquid inlet and a liquid outlet. The valve cavity of the liquid inlet valve is connected to the liquid inlet, and the valve cavity of the liquid outlet valve is connected to the liquid outlet. In this embodiment, the locking hook driver 530 is an oil cylinder. The liquid inlet valve is provided at the liquid inlet of the oil cylinder, and the liquid outlet valve is provided at the liquid outlet of the oil cylinder. When the oil cylinder drives the second locking hook 520 to hook with the first locking hook 510, the liquid inlet valve and the liquid outlet valve can be closed, so that the second locking hook 520 is bidirectionally positioned. The liquid inlet valve and the liquid outlet valve can further prevent oil leakage from the oil cylinder. At this time, the first locking hook 510 can be restricted by the second locking hook 520 to move away from the blowing mechanism 300, and the second locking hook 520 will not excessively pull the mold shifting mechanism 400 close to the blowing mechanism 300, so that the position of the mold shifting mechanism 400 remains appropriate.
[0037] Specifically, the second locking hook 520 is extended and retracted by a hydraulic cylinder to achieve linear movement relative to the base 100. It is understandable that the second locking hook 520 can also be slidably connected to the base 100 through a slide rail and slider structure, and driven by a hydraulic cylinder to slide linearly.
[0038] In the embodiment, the first locking hook 510 includes a first arm 511 and a first hook rod 512, wherein the first arm 511 is perpendicular to the first hook rod 512 and the first hook rod 512 is inclined relative to the first axis. The second locking hook 520 includes a second arm 521 and a second hook rod 522, wherein the second arm 521 is perpendicular to the second hook rod 522 and the first hook rod 512 and the second hook rod 522 are parallel to each other. The first hook rod 512 and the second hook rod 522 are parallel to each other and both are inclined relative to the first axis. When the first hook rod 512 and the second hook rod 522 are connected, the second locking hook 520 can provide a component of force along the first axis to the first locking hook 510 to restrict the movement of the mold shifting mechanism 400. The connection between the first locking hook 510 and the second locking hook 520 is not easy to loosen. In addition, the structures of the first locking hook 510 and the second locking hook 520 are relatively simple and easy to manufacture. It is conceivable that in other embodiments, the first locking hook 510 and the second locking hook 520 may also have other shapes, such as an arc shape.
[0039] In the embodiment, the first hook rod 512 is provided with a protrusion 513, and the second hook rod 522 has a groove 523. The protrusion 513 is adapted to the groove 523, so that the first locking hook 510 and the second locking hook 520 are not prone to relative looseness when hooked, and the use effect is better.
[0040] It is conceivable that in other embodiments, the second lock hook 520 may also be pivotally connected to the base 100, and connected to or separated from the first lock hook 510 by rotation. In this case, the lock hook driver 530 may be a reduction motor or a rotary cylinder.
[0041] It is conceivable that in other embodiments, the locking mechanism 500 can also be other structures. For example, the locking mechanism 500 includes a cylinder and a pin installed on the machine base 100, and a pin hole is set in the mold shifting mechanism 400. The pin hole is perpendicular to the first axis direction, and the cylinder drives the pin to be inserted into or pulled out of the pin hole to lock or unlock the mold shifting mechanism 400.
[0042] In this embodiment, the blowing mechanism 300 includes a blow needle 310, which is arranged at an angle relative to the first axis and has a blow hole. By providing the blow hole with the blow needle 310, the blow needle 310 can be inserted into the preform of the blow mold to blow air, achieving a better blowing effect. It is conceivable that in other embodiments, the blow hole can be provided by a blow block, and blowing can be performed when the surface of the blow block directly and sealingly abuts the air inlet of the blow mold.
[0043] Furthermore, the force component along the first axis in the past caused the mold moving mechanism 400 to loosen and move away from the blowing mechanism 300, which also affected the sprue cutting. Therefore, in the embodiment, the blowing needle 310 is movably arranged on the machine base 100 along its length direction, and the blowing mechanism 300 also includes a blowing needle driver 320, which is connected to the blowing needle 310 and is used to drive the blowing needle 310 to move. Specifically, the blowing needle driver 320 can be an oil cylinder, an electric cylinder or an air cylinder, etc. The blowing needle 310 is driven by the blowing needle driver 320 to be inserted into the material blank of the blow mold for blowing. After the blowing is completed, the blowing needle 310 is driven by the blowing needle driver 320 to pull out of the blow mold, which is beneficial to the blow molding of the hollow plastic product by the material blank. In addition, during the expansion and contraction of the blowing needle 310, the shear ring can be driven to cut off the sprue waste.
[0044] Specifically, the axis of the blow hole and the first axis are located in the same vertical plane, the blow molding machine has a compact structure and a good use effect. It is understandable that the axis of the blow hole can be located in other vertical planes.
[0045] In an embodiment, the mold shifting mechanism 400 includes a mold shifting frame 410 and a mold opening and closing assembly 420. The mold shifting frame 410 is slidably connected to the base 100 along a first axis. A mold shifting driver is used to drive the mold shifting frame 410 to slide. The mold opening and closing assembly 420 is disposed on the mold shifting frame 410, and the mold opening and closing assembly 420 has a mold mounting position. Specifically, the mold shifting frame 410 can slide relative to the base 100 via a slide rail and slider structure or a guide column and guide sleeve structure. The corresponding mold shifting driver is also a hydraulic cylinder, and the liquid inlet and outlet valves are connected to the liquid inlet and outlet. When the mold shifting frame 410 needs to be fixed in the blow molding station 120, the liquid inlet and outlet valves are closed. Even if the mold shifting frame 410 is subjected to thrust along the first axis, the hydraulic cylinder can maintain its fixed position. When the mold shifting frame 410 needs to be moved, the liquid inlet and outlet valves are opened, and the hydraulic cylinder can then drive the mold shifting frame 410 to slide. It is conceivable that in other embodiments, the mold moving driver may also be a structure such as an electric cylinder or a linear motor to drive the mold moving frame 410 to move linearly.
[0046] Specifically, the mold opening and closing assembly 420 can be two carriers, which are driven by a cylinder or the like to move closer to or away from each other to achieve the opening and closing of the blow mold.
[0047] It is conceivable that the mold shifting mechanism 400 may also be a trolley structure, which moves between the embryo loading station 110 and the blow molding station 120 by means of rollers.
[0048] Specifically, the preform mechanism 200 is an existing preform extrusion mechanism that heats plastic and extrude it to form a preform for blow molding. It is understood that in other embodiments, the preform structure can also be a robot that places the preform into the blow mold.
[0049] Specifically, the machine base 100 is provided with a blow needle rack, and the blow needle 310 , the blow needle driver 320 , the second locking hook 520 and the locking hook driver 530 are all arranged on the blow needle rack.
[0050] Specifically, the blowing mechanism 300 supplies air through an air pump or an air tank.
[0051] Specifically, the oblique-mouth blow molding machine of the present invention can be used to make plastic bottles. It is understandable that the oblique-mouth blow molding machine of the present invention can also be used to blow mold and make other types of products.
