Description

Technical Field

[0001] This utility model relates to the field of blow molding machine technology, specifically a blow molding die for blow molding machines. Background Technology

[0002] A blow molding machine is an automated device that heats and softens plastic raw materials and then blows them into specific shapes using air pressure or mechanical force. It is widely used in the production of plastic containers in industries such as food and beverage, daily chemicals, and pharmaceuticals. Its core principle is to utilize the thermoplasticity of plastics to achieve mass production of containers through a process of "heating-shaping-cooling".

[0003] The blow molding die of a blow molding machine is the core component of the blow molding process. Its function is to define the final shape of the plastic bottle by defining the shape of the cavity, which directly affects the dimensional accuracy, appearance quality and structural strength of the bottle. The core part of the die has an inner wall shape that is completely consistent with the outer surface of the finished plastic bottle, and it needs to be precisely machined according to the product design.

[0004] The prior art patent document CN210257225U discloses a blow molding die for a blow molding machine. When blowing a bottle, the preform is placed in the preform placement opening on the moving template. The mold opening and closing mechanism drives the moving template to move closer to the fixed template to close the mold. After the mold closes, the position of the moving template is locked by the moving template locking mechanism. Then, the blow molding machine blows air into the preform. The moving template locking mechanism and the mold opening and closing mechanism share the pressure, which reduces the wear of the mold opening and closing mechanism and extends its service life.

[0005] Although the existing technology described above utilizes the moving template locking mechanism and the mold opening and closing mechanism to share the pressure, reducing the wear of the mold opening and closing mechanism and extending its service life, the mold in this patented technology is not easy to replace. Nowadays, enterprises need to produce bottles of different sizes, which requires different molds. If the mold cannot be easily replaced, it will affect the production efficiency and reduce the practicality of the blow molding mold. Therefore, we need a blow molding mold for blow molding machines.

[0018] First, this utility model is equipped with an installation groove, an installation block, a fixing groove, a fixing rod, a knob, a lead screw, and a connecting plate. By turning the knob by hand, the lead screw can be rotated, which in turn causes the two connecting plates to move relative to each other. One side of the connecting plate is fixed to the fixing rod, which allows control over the movement of the two fixing rods. When the two fixing rods move inward at the same time, the installation block can be fixed, allowing the template to be installed.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 A blow molding die for a blow molding machine includes a base 1, a support column 2 fixedly connected to the top of the base 1, a hydraulic cylinder 3 installed on one side of the support column 2, a movable plate 4 fixedly connected to one end of the hydraulic cylinder 3, an mounting plate 5 provided on one side of the movable plate 4, an mounting assembly 6 installed inside the mounting plate 5, and a cooling assembly 8 provided on the top of the base 1.

[0027] Mounting component 6 includes mounting groove 601, mounting block 602 is engaged with the inner wall of mounting groove 601, fixing groove 603 is provided on one side of mounting block 602, fixing rod 604 is engaged with the inner wall of fixing groove 603, knob 605 is provided on the top of mounting plate 5, and lead screw 606 is installed on one side of knob 605, connecting plate 607 is threaded to the outer surface of lead screw 606;

[0028] The cooling assembly 8 includes a first motor 801, the output end of which is detachably connected to a screw 802 via a coupling, and a lifting block 803 is threadedly connected to the outer surface of the screw 802. A water tank 804 is fixedly connected to the top of the base 1, and a second motor 805 is installed at the bottom of the base 1. A connecting rod 806 is detachably connected to the output end of the second motor 805 via a coupling, and a blade 807 is fixedly connected to one end of the connecting rod 806.

[0029] Through the above technical solution, by manually turning the knob 605, the lead screw 606 can be rotated, which in turn causes the two connecting plates 607 to move relative to each other. One side of the connecting plate 607 is fixed to the fixing rod 604, which allows control over the movement of the two fixing rods 604. When the two fixing rods 604 move inward at the same time, the mounting block 602 can be fixed, allowing the template 7 to be installed. When the fixing rods 604 move outward, the fixing of the mounting block 602 can be released, making the template 7 easy to disassemble. This achieves the effect of convenient and quick replacement of the template 7, improving the practicality of the mold.

[0030] Specifically, a template 7 is installed on one side of the mounting plate 5.

[0031] Through the above technical solution, two templates 7 are brought close together to form a mold, and the inner cavities of the templates 7 are merged to form a bottle shape.

[0032] Specifically, the mounting plate 5 forms a locking structure with the mounting block 602 through the mounting groove 601, and the shape and size of the mounting groove 601 match the shape and size of the mounting block 602. One side of the mounting block 602 is connected to one side of the template 7.

[0033] The above technical solution facilitates the insertion of the mounting block 602 into the mounting groove 601 to connect with the mounting plate 5, so that the mounting block 602 is fixed in the mounting groove 601 and the mounting plate 5. Because the mounting block 602 is fixed with the template 7, the template 7 can be initially installed by the mounting block 602 and the mounting plate 5.

[0034] Specifically, the mounting block 602 forms a locking structure with the fixing rod 604 through the fixing groove 603, and one end of the fixing rod 604 extends into the inner wall of the fixing groove 603 for connection.

[0035] The above technical solution facilitates the installation of the fixing rod 604 into the fixing groove 603 and the mounting block 602, and the fixing rod 604 can also be disengaged from the fixing groove 603 to release the limiting fixation of the mounting block 602, thus facilitating the fixing and unfixing of the mold.

[0036] Specifically, the knob 605 forms a lifting structure with the lead screw 606 and the connecting plate 607, and the external thread of the lead screw 606 matches the internal thread of the connecting plate 607. There are two connecting plates 607.

[0037] Through the above technical solution, it is convenient to manually turn the knob 605 to drive the lead screw 606 to rotate and simultaneously drive the connecting plate 607 to rise and fall. Because the threads on both sides of the lead screw 606 turn in opposite directions, and the two connecting plates 607 are symmetrically arranged at both ends of the lead screw 606, the rotation of the lead screw 606 will drive the two connecting plates 607 to move relative to each other. The shape of the connecting plate 607 matches the shape of the groove opened on the inner wall of the mounting plate 5. Since the connecting plate 607 is fixed to the fixing rod 604, the connecting plate 607 can control the movement of the fixing rod 604, thereby achieving the effect of facilitating the assembly and disassembly of the template 7.

[0038] Specifically, the first motor 801 forms a lifting structure with the lifting block 803 via the screw 802, and one side of the lifting block 803 is connected to one side of the mounting plate 5.

[0039] The above technical solution facilitates the starting of the first motor 801, which drives the screw 802 to rotate and simultaneously drives the lifting block 803 to rise and fall. The shape of the lifting block 803 matches the shape of the groove opened on the inner wall of the moving plate 4. Since one side of the lifting block 803 is connected to the mounting plate 5, the template 7 installed on one side of the mounting plate 5 is raised and lowered. The two first motors 801 are controlled in parallel, so that the two screws 802 drive the two lifting blocks 803 to rise and fall at the same time, so that the mold can rise and fall stably. The mold can be partially inserted into the water tank 804 and cooled by the water in the water tank 804, which improves the speed of bottle molding.

[0040] Specifically, the second motor 805 forms a rotating structure with the blade 807 via the connecting rod 806, and the blade 807 is installed inside the water tank 804 to rotate.

[0041] The above technical solution facilitates the starting of the second motor 805, which can drive the connecting rod 806 to rotate while simultaneously driving the blade 807 to rotate. The blade 807 can agitate the water in the water tank 804, thereby improving the cooling effect on the mold.

[0042] Working Principle: When using the blow molding die of this blow molding machine, the device is equipped with an external power supply to power the necessary equipment. When changing the die, first manually turn knob 605. Knob 605 drives screw 606 to rotate, which in turn moves two connecting plates 607 outward. Connecting plates 607 then move fixing rod 604 outward, disengaging it from the fixing groove 603 and releasing mounting block 602. Then, the mounting block 602 on one side of template 7 is pulled out of the mounting groove 601. The same operation is performed on both templates 7. Next, the mounting block 602 on the side of the template 7 to be used is inserted into the mounting groove 601 and connected to the mounting plate 5. Turn knob 605 over, which, through screw 606, moves connecting plate 607 inward, allowing fixing rod 604 to move outward. 4. Insert the platen into the fixing groove 603 to fix the mounting block 602, completing the mold replacement. Then, when cooling the mold, simply start the two first motors 801 in parallel. The first motors 801 drive the screw 802 to rotate, the screw 802 drives the lifting block 803 to move downward, and the lifting block 803 drives the mold on the mounting plate 5 to move downward, so that the mold extends into the water tank 804 and is cooled by the water in the water tank 804. At the same time, start the second motor 805, the second motor 805 drives the connecting rod 806 to rotate, the connecting rod 806 drives the blade 807 to rotate, and the blade 807 stirs the water in the water tank 804, thereby improving the cooling effect. This completes all the work. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit defined by the appended claims and their equivalents.
