[0035] Among them, the power source 200 is installed above the box-type mounting frame 100.

[0036] The mold clamping assembly includes a first mold clamping assembly 300, a second mold clamping assembly 400, and a third mold clamping assembly 500. The first mold clamping assembly 300 is installed at the internal central position of the box-type mounting frame 100 and is drivingly connected to the power source 200, and first templates 310 are provided on both sides of the first mold clamping assembly 300; the second mold clamping assembly 400 is installed on the left side inside the box-type mounting frame 100, and corresponding second templates 410 are also provided at the end of the second mold clamping assembly 400; similarly, the third mold clamping assembly 500 is installed on the right side inside the box-type mounting frame 100, and corresponding third templates 510 are also provided at the end of the third mold clamping assembly 500;

[0037] In another embodiment of the present utility model, as Figures 1 - 3As shown in the figure, the first mold clamping assembly 300, the second mold clamping assembly 400 and the third mold clamping assembly 500 all include a bearing seat 320, a rotating shaft 330, a rotating disk 340, a connecting push rod 350, a pushing assembly 360 and a guiding assembly 370. The bearing seat 320 is fixedly installed on the box-type mounting frame 100, and the rotating shaft 330 is rotatably installed on the bearing seat 320. In the first mold clamping assembly 300, the rotating shaft 330 is also fixedly connected to the output end of the power source 200. On one side of the rotating disk 340 away from the rotating shaft 330, there is an eccentric convex column 341. The eccentric convex column 341 is movably connected to the first end of the connecting push rod 350. The second end of the connecting push rod 350 is connected to the pushing assembly 360. The two pushing assemblies 360 are respectively connected to the corresponding first templates 310 on both sides. The bottoms of the two first templates 310 are further correspondingly connected to the guiding assembly 370. In the second mold clamping assembly 400 and the third mold clamping assembly 500, on the side of the rotating disk 340 away from the axis, there is also an eccentric convex column 341. The eccentric convex column 341 is movably connected to the first end of the connecting push rod 350. The second end of the connecting push rod 350 is connected to the pushing assembly 360. The two pushing assemblies 360 are respectively connected to the second template 410 and the third template 510 correspondingly. The bottoms of the second template 410 and the third template 510 are respectively correspondingly connected to the guiding assembly 370.

[0038] On the box-type mounting frame 100, the mold clamping assemblies are connected by a transmission device 600. The transmission device 600 includes a left transmission component 610 and a right transmission component 620. One end of the left transmission component 610 is drivingly connected to the power source 200, and the other end is drivingly connected to the second mold clamping assembly 400. One end of the right transmission component 620 is drivingly connected to the power source 200, and the other end is drivingly connected to the third mold clamping assembly 500.

[0039] In the present utility model, by providing a power source 200, the two first mold clamping assemblies 300 are drivingly connected to the output end of the power source 200. The left transmission component 610 and the right transmission component 620 are respectively drivingly connected to the output end of the power source 200. Then, the left transmission component 610 is connected to the second mold clamping mechanism 400, and the right transmission component 620 is connected to the third mold clamping mechanism 500. When the power source operates, due to the driving connection of the transmission device 600, the first mold clamping assembly 300, the second mold clamping assembly 400 and the third mold clamping assembly 500 move synchronously, so that the first template 310, the second template 410 and the third template 510 are opened or closed synchronously. The whole mechanism has a simple structure. By using one power source to control the work of four mold clamping assemblies simultaneously, it realizes energy saving, improves the utilization efficiency of the motor, reduces the production cost, and improves the production efficiency.

[0040] Further, as Figure 4As shown in the figure, the above-mentioned transmission device 600 includes two belt teeth 611, a belt 612. One belt tooth 611 of the left transmission component 610 is drivingly connected to the output end of the power source 200, and its other belt tooth 611 is connected to the rotating shaft 330 of the second mold clamping component 400; one belt tooth 611 of the right transmission component 620 is also drivingly connected to the output end of the power source 200, and its other belt tooth 611 is fixedly connected to the rotating shaft 330 of the third mold clamping component 500. When the power source operates, the left and right transmission components also operate synchronously.

[0041] Further, the power source 200 can preferably be a servo motor, or it can also be a general motor. Of course, in actual production, other power sources can also be used for driving, as long as it can meet the requirement of synchronously operating the mold clamping components. Therefore, the present invention does not limit the power source.

[0042] In another embodiment of the present invention, as Figure 3 shown, the pushing component 360 includes a plurality of transverse linkage structures 361 and longitudinal connecting rods 362. Both sides of each transverse linkage structure 361 of the first mold clamping component 300 are respectively connected to the side walls of the two first templates 310; each transverse linkage structure 361 of the second mold clamping component 400 is connected to one side of the box-type mounting frame 100, and the other end of each transverse linkage structure 361 of the second mold clamping component 400 is connected to the second template 410; each transverse linkage structure 361 of the third mold clamping component 500 is connected to the other side of the box-type mounting frame 100, and each transverse linkage structure 361 of the third mold clamping component 500 is connected to the third template 510; the longitudinal connecting rods 362 connect and drive each transverse linkage structure 361. Specifically, in this embodiment, by setting a plurality of transverse linkage structures 361, in the case of only using one power source 200, the motion is synchronously transmitted by the transmission device 600 to the connecting push rods 350 of each mold clamping component. The connecting push rods 350 then push each transverse linkage structure 361 to move, and the longitudinal connecting rods 362 drive each transverse linkage structure 361 to move synchronously, further synchronously pushing the first template 310, the second template 410, and the third template 510. Thus, a power source drives a multi-stage linkage structure, making the drive stable and maximizing the utilization of the power of the power source.

[0043] In another embodiment of the present invention, as Figure 5As shown in the figure, the horizontal linkage structure 361 includes a linkage shaft 3611, a first pivot block 3612, and a second pivot block 3613. The linkage shaft 3611 is movably connected to the second end of the connecting push rod 350. One end of the first pivot block 3612 and the second pivot block 3613 of the first mold clamping assembly 300 are both pivotally connected to the linkage shaft 3611, and the other ends of the two pivot blocks are respectively pivotally connected to the side walls of the two first templates 310; one end of the first pivot block 3612 and the second pivot block 3613 of the second mold clamping assembly 400 are both pivotally connected to the linkage shaft 3611, and the other end of the first pivot block 3612 is pivotally connected to one side of the box-type mounting frame 100, and the second pivot block 3613 is pivotally connected to the side wall of the second template 410; one end of the first pivot block 3612 and the second pivot block 3613 of the third mold clamping assembly 500 are both pivotally connected to the linkage shaft 3611, and the other end of the first pivot block 3612 is pivotally connected to one side of the box-type mounting frame 100, and the second pivot block 3613 is pivotally connected to the side wall of the third template 510. The linkage shaft 3611 drives the first template 310, the second template 410, and the third template 510 to open and close synchronously along the guiding assembly 370 through the first pivot block 3612 and the second pivot block 3613.

[0044] In another embodiment of the present utility model, as Figure 3 shown, each guiding assembly 370 includes a guiding slide rail and a guiding slider. The guiding slide rails are all installed at the bottom of the box-type mounting frame 100, and the guiding sliders are slidably installed on the guiding slide rails. Each guiding slider of the first mold clamping assembly 300 is connected to the two first templates 310, each guiding slider of the second mold clamping assembly 400 is connected to the second template 410, and each guiding slider of the third mold clamping assembly 500 is connected to the third template 510. Specifically, the guiding assembly 370 cooperates with the mechanical hinge, so as to ensure that the first mold clamping assembly 300, the second mold clamping assembly 400, and the third mold clamping assembly 500 can move in a straight-line and balanced manner along the guiding slide rails of the guiding assembly 370, ensuring the stability of the overall movement of the mold clamping mechanism, and further improving the stability of the overall structural movement of the mold clamping mechanism of the blow molding machine.

[0045] The number of the guiding components 370 is at least set to 4. In this embodiment, it is set to 8, and is further divided into a first guiding component 370a and a second guiding component 370b. The first guiding component 370a includes a first guiding slide rail 371 and a first guiding slider 372, and the second guiding component 370b includes a second guiding slide rail 373 and a second guiding slider 374. Specifically, by setting the guiding components 370 to eight, the first mold clamping component 300 is connected to four first guiding components 370a, the second mold clamping structure 400 is connected to two second guiding components 370b, and the third mold clamping structure is also connected to two second guiding components 370b, so that the guiding force received by the mold clamping mechanism is balanced, thus ensuring the smooth movement of each mold clamping mechanism, and realizing mold clamping accordingly.

[0046] Furthermore, in this embodiment, the box-type mounting frame 100 is designed in a box shape. The power source 200 is installed on the box-type mounting frame 100. The first mold clamping component 300 is arranged in the middle side inside the box-type mounting frame 100. The second mold clamping component 400 and the third mold clamping component 500 are respectively installed on both sides of the box-type mounting frame 100 and are respectively connected to the side walls of the box-type mounting frame 100. Then, they are respectively connected to the corresponding guiding components 370 through the mold clamping components and mechanical hinges, so that the mold clamping components can move smoothly for opening and closing. It should be noted that support columns 110 are respectively arranged on the front and rear sides of the central position of the first mold clamping component 300. The support columns 110 are fixedly installed inside the box-type mounting frame 100, and the first mold clamping component 300 is also fixedly connected to the support columns 110, strengthening the stability of the overall structure. Moreover, the first mold clamping component 300, the second mold clamping component 400 and the third mold clamping component 500 are installed on one device and are driven by one power source, realizing the combination of one device and two working stations, which not only simplifies the device structure, reduces the production cost, but also improves the production efficiency.

[0047] Its working principle: As Figure 6 shown, the power source 200 drives the rotation of its output shaft and transmits the power to the left transmission component 610 and the right transmission component 620. The left transmission component 610 and the right transmission component 620 drive the corresponding rotating disks 340 to rotate. The rotating disks 340 drive the connecting push rods 350 to perform eccentric motions through the eccentric convex columns 341. The connecting push rods 350 drive the linkage shafts 3611 of the respective mold clamping components to move. The respective linkage shafts 3611 drive the corresponding pushing components 360 to operate. Then, the respective pushing components 360 drive the respective templates to move smoothly through the respective guiding sliders on the guiding slide rails, realizing the synchronous opening and closing of the first template 310 and the second template 410, and the first template 310 and the third template 510, and further realizing the mold clamping work, so as to achieve simultaneous operation of two working stations.

[0048] It should be noted that cavity half-molds (not shown in the figures) and core half-molds (not shown in the figures) of the mold are correspondingly installed on the opposite faces of the first template 310 and the second template 410, and the first template 310 and the third template 510. For example, when the first template 310 and the second template 410 are combined, the cavity half-mold and the core half-mold form a mold cavity, and the mold cavity is used to form a product. It should be noted that the cavity half-mold and the core half-mold are prior arts, so the specific shapes of the cavity half-mold and the core half-mold are not specifically shown in this application. In addition, how to form a product in the mold cavity should be well-known and mastered by those of ordinary skill in the art, and it is not the focus protected by this application, so this application does not specifically elaborate on this.

[0049] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
