[0031] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the embodiments of the present application. Obviously, the described embodiments of the present application are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present application

[0032] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the following drawings are used to distinguish similar objects, and do not necessarily need to describe a specific order or sequence. It should be understood that such objects can be interchanged under appropriate circumstances so that the embodiments of the present application described here can be implemented in an order other than those illustrated or described here. In addition, the terms "including" and "having" and any variations thereof are intended to cover non - exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices

[0033] For ease of description, spatial relative terms, such as "above", "over", "on the upper surface", "upper", etc., may be used herein to describe the spatial positional relationship of one device or feature to other devices or features as shown in the figures. It should be understood that the spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is inverted, the device described as "above" or "over" other devices or structures will then be positioned "below" or "under" the other devices or structures. Thus, the exemplary term "above" can include both the orientations of "above" and "below". The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations are made for the spatial relative descriptions used herein.

[0034] Embodiment: As Figure 1-8 shown, an injection blow molding die includes an injection fixed die mechanism 100, a blow molding fixed die mechanism 200, a moving die mechanism 300, a first driving mechanism, and a second driving mechanism. The first driving mechanism can drive the moving die mechanism 300 to be respectively located at a first working position and a second working position. The second driving mechanism can drive the moving die mechanism 300 to be clamped and opened with the injection fixed die mechanism 100, or the moving die mechanism 300 to be clamped and opened with the blow molding fixed die mechanism 200. The moving die mechanism 300 has a first working position and a second working position. When the moving die mechanism 300 is in the first working position, the moving die mechanism 300 is arranged in alignment with the injection fixed die mechanism 100. When the moving die mechanism 300 is in the second working position, the moving die mechanism 300 is arranged in alignment with the blow molding fixed die mechanism 200.

[0035] When the moving die mechanism 300 runs to the first working position under the action of the first driving mechanism, the second driving mechanism can drive the moving die mechanism 300 to be clamped with the injection fixed die mechanism 100 to complete the injection process of the product embryo 328, that is, the product embryo 328 is injection-molded in the die. After injection, the second driving mechanism drives the moving die mechanism 300 to separate the product embryo 328 from the injection fixed die mechanism 100, that is, the product embryo 328 does not need to be removed from the moving die mechanism 300. The first driving mechanism drives the moving die mechanism 300 to rotate to the second working position, and the second driving mechanism drives the moving die mechanism 300 to be clamped with the blow molding fixed die mechanism 200 and complete the blow molding process of the product embryo 328 to form a finished product 329. That is, the product embryo 328 is blow-molded into the finished product 329 in the blow molding positioning mechanism 200, and the second driving mechanism (not shown in the figure) drives the moving die mechanism 300 to perform a linear motion to complete the clamping and opening actions of the die.

[0036] Optionally, the second driving mechanism can adopt common linear modules, linear cylinders, linear motors, etc. This application includes an injection molding fixed mold mechanism 100, a blow molding fixed mold mechanism 200, and a moving mold mechanism 300. The injection molding fixed mold mechanism 100 and the blow molding fixed mold mechanism 200 are arranged in parallel, and the injection molding fixed mold mechanism 100 and the blow molding fixed mold mechanism 200 are located on the same side of the moving mold mechanism 300. Among them, the finished product 329 is processed through two processes of injection molding and blow molding.

[0037] When this application is running, after injection molding is completed, the moving mold mechanism 300 drives the product mold embryo 328 to disengage from the injection molding fixed mold mechanism 100 and return to the first working position. Then, under the action of the first driving mechanism, the moving mold mechanism 300 drives the product mold embryo 328 to rotate to the second working position. Then, under the action of the second driving mechanism, the moving mold mechanism 300 drives the product mold embryo 328 to be clamped with the blow molding fixed mold mechanism 200 to complete the blow molding process to obtain the finished product 329. Therefore, during the process of transferring the product mold embryo 328 from the injection molding fixed mold mechanism 100 to the blow molding fixed mold mechanism 200 in this application, the product mold embryo 328 does not need to be disengaged from the moving mold mechanism 300, thereby ensuring the integrity of the product mold embryo 328, improving the production qualification rate of the product, simplifying the production process of the product, and improving the processing efficiency of the product.

[0038] As Figure 1 and Figure 2 shown, the injection-blow molding die further includes a machine table 600. A fixed mold side machine table panel 610 and a moving mold side machine table panel 620 are fixedly provided on the machine table 600. The injection molding fixed mold mechanism 100 and the blow molding fixed mold mechanism 200 are fixedly installed on the fixed mold side machine table panel 610, and the moving mold mechanism 300 is fixedly installed on the moving mold side machine table panel 620. The first driving mechanism is fixedly installed on the machine table 600. The first driving mechanism is connected to the moving mold side machine table panel 620 and the first driving mechanism can drive the moving mold side machine table panel 620 to rotate so that the moving mold mechanism 300 can be switched between the first working position and the second working position.

[0039] Optionally, the first driving mechanism (not shown in the figure) is a rotary motor or a rotary cylinder. In a possible implementation, the first driving mechanism is a rotary motor, and the rotating shaft of the rotary motor is fixedly connected to the moving mold side machine table panel 620. There are two sets of moving mold mechanisms 300 symmetrically arranged along the rotating shaft on the moving mold side machine table panel 620. One set of the moving mold mechanisms 300 is located at the first working position, and the other set of the moving mold mechanisms 300 is located at the second working position. After the first driving mechanism drives the moving mold side machine table panel to rotate 180°, the positions of the two moving mold mechanisms 300 are just swapped, so as to complete the switching of the moving mold mechanism 300 between the injection molding fixed mold mechanism 100 and the blow molding fixed mold mechanism 200. In this application, two sets of moving mold mechanisms 300 are provided on the moving mold side machine table panel 620, and the two sets of moving mold mechanisms 300 simultaneously complete the injection molding process and the blow molding process respectively, improving the production efficiency of the product; the switching of the moving mold mechanism 300 between the injection molding fixed mold mechanism 100 and the blow molding fixed mold mechanism 200 is completed by rotating the moving mold side machine table panel 620 at the original position, simplifying the overall structure of the injection-blow molding die and reducing the occupied space of the die.

[0040] As Figure 1 , Figure 3 and Figure 4 shown, the moving mold mechanism 300 includes a moving mold core assembly 320. The moving mold core assembly 320 includes a first moving mold core 321 and a second moving mold core 322. The second moving mold core 322 is connected to the first cylinder 311. During blow molding, as Figure 5-8 shown, the first cylinder 311 can drive the second moving mold core 322 to operate to form a blowing port 327 between the first moving mold core 321 and the second moving mold core 322. The first moving mold core 321 and the second moving mold core 322 are used for the molding of the product blank 328. Among them, the first moving mold core 321 is sleeved on the second moving mold core 322. The first moving mold core 321 is used for the molding of the bottle mouth of the product blank 328, and the second moving mold core 322 is used for the molding of the bottle body of the product blank 328. After the moving mold mechanism 300 is separated from the injection molding fixed mold mechanism 100, the molded product blank 328 is sleeved on the first moving mold core 321 and the second moving mold core 322. As Figure 3 shown, a blowing channel 326 is provided in the moving mold mechanism 300. After the moving mold mechanism 300 is clamped with the blow molding fixed mold mechanism 200, the first cylinder 311 drives the second moving mold core 322 to move towards the blow molding fixed mold mechanism 200, so that a gap is generated between the second moving mold core 322 and the product blank 328, that is, the blowing port 327 is formed, and external gas enters the product blank 328 through the blowing channel 326 and the blowing port 327 to blow the product thin to form the finished product 329.

[0041] As Figure 3 and Figure 4As shown, the moving mold core assembly 320 further includes a first moving mold core fixing plate 323, a second moving mold core fixing plate A 324, and a second moving mold core fixing plate B 325. The first moving mold core 321 is fixedly connected to the first moving mold core fixing plate 323, and the second moving mold core 322 is fixedly connected to the second moving mold core fixing plate A 324 and the second moving mold core fixing plate B 325. The first cylinder 311 is connected to the second moving mold core fixing plate A 324.

[0042] The moving mold mechanism 300 further includes a retaining ring fixing plate 330. The retaining ring fixing plate 330 is fixedly connected to a retaining ring 331 and a second cylinder. The second cylinder can drive the retaining ring 331 to operate to demold the finished product 329. As Figure 4 shown, the moving mold mechanism 300 further includes a moving mold base plate 310. The moving mold core assembly 320 includes a first moving mold core 321, a second moving mold core 322, a first moving mold core fixing plate 323, a second moving mold core fixing plate A 324, and a second moving mold core fixing plate B 325. The moving mold base plate 310 is fixedly installed on the moving mold side machine table panel 620. The first moving mold core fixing plate 323 is located between the moving mold base plate 310 and the retaining ring fixing plate 330. The second moving mold core fixing plate A 324 and the second moving mold core fixing plate B 325 are movably installed on the moving mold base plate 310, and the first cylinder 311 is installed on the moving mold base plate 310.

[0043] As Figure 1-4 and Figure 8 shown, the injection blow molding mold further includes a movable plate 400 and an associated mechanism 500. The first side of the movable plate 400 is movably connected to the moving mold mechanism 300 through the associated mechanism 500, and the second side of the movable plate 400 is movably connected to the injection fixed mold mechanism 100 or the blow molding fixed mold mechanism 200 through the associated mechanism 500. When the mold is opened, the moving mold mechanism 300 drives the movable plate 400 to move together in a direction away from the injection fixed mold mechanism 100 or the blow molding fixed mold mechanism 200. After running a certain distance, the movable plate 400 disengages from the moving mold mechanism 300, the movable plate 400 stops running, and the moving mold mechanism 300 continues to run to the demolding position. In this application, the movable plate 400 is used to complete the segmented demolding of the finished product.

[0044] As Figure 8As shown, the linkage mechanism 500 includes a first connecting rod 510, a second connecting rod 520, and a limiting member 530. A first stop portion 511 is provided at the first end of the first connecting rod 510. The second end of the first connecting rod 510 is fixedly installed on the injection molding fixed mold mechanism 100 or the blow molding fixed mold mechanism 200. The first end of the second connecting rod 520 is fixedly installed on the moving mold mechanism 300. A second stop portion 521 is provided at the second end of the second connecting rod 520. The limiting member 530 is fixedly installed on the movable plate 400. The first connecting rod 510 passes through the limiting member 530 and the limiting member 530 can block the first stop portion 511. The second stop portion 521 interferes with the limiting member 530. An installation groove is provided on the limiting member 530. The first connecting rod 510 passes through the installation groove of the limiting member 530. The width of the first stop portion 511 is greater than the width of the installation groove. The second stop portion 421 interferes with the side wall of the limiting member 530. As Figure 8 shown, during demolding, when the moving mold mechanism 300 moves away from the blow molding fixed mold mechanism 200, due to the interference between the second connecting rod 520 and the limiting member 530, the moving mold mechanism 300 drives the movable plate 400 to move synchronously until the limiting member 530 moves to the position of the first stop portion 511. The limiting member 530 prevents the movable plate 400 from further moving. The movable plate 400 is separated from the moving mold mechanism 300. After the moving mold mechanism 300 continues to move to a preset position, the retaining ring 331 moves forward under the drive of the retaining ring fixing plate 330 to demold the finished product 329.

[0045] As Figure 1 and Figure 4 shown, a reverse beam block 410 is fixedly connected to the movable plate 400. A movable slider 420 is provided on the movable plate 400. The slider 420 can move towards the direction close to the moving mold core assembly 320 or move away from the moving mold core assembly 320.

[0046] As Figure 3 and Figure 4 shown, the injection molding fixed mold mechanism 100 includes an injection molding fixed template 140. A first dial block 141 and a first beam block 142 are fixedly provided on the injection molding fixed template 140. The first dial block 141 can be inclined to insert into the slider 420 to drive the slider 420 to slide. The reverse beam block 410 and the first beam block 142 are in inclined surface cooperation. The first beam block 142 and the slider 420 are in inclined surface cooperation. A hot runner insert 143 is provided in the injection molding fixed template 140. As Figure 1As shown, the injection molding fixed mold machine 100 further includes an injection molding fixed mold base plate 110, injection molding fixed mold feet 120, and an injection molding carrier plate 130. The two sides of the injection molding fixed mold feet 120 are respectively fixedly connected to the injection molding fixed mold base plate 110 and the injection molding carrier plate 130. When the mold is closed, the first slider 141 drives the slider 420 to move towards the inside of the mold to form the cavity of the product. When the mold is opened, the first slider 141 drives the slider 420 to move towards the outside of the mold to separate the slider from the product mold embryo 328.

[0047] As Figure 5-7 shown, the blow molding fixed mold mechanism 200 includes a blow molding fixed mold plate 240. A second slider 241 and a second beam block 242 are fixedly arranged on the blow molding fixed mold plate 240. The second slider 241 can be inserted into the slider 420 obliquely to drive the slider 420 to slide. The anti-beam block 410 and the second beam block 242 are in inclined surface fit, and the second beam block 242 and the slider 420 are in inclined surface fit. A blow molding fixed mold core 243 and a blow film fixed mold cavity 244 are arranged in the blow molding fixed mold plate 240. As Figure 1 shown, the blow molding fixed mold machine 200 further includes a blow molding fixed mold base plate 210, blow molding fixed mold feet 220, and a blow molding carrier plate 230. The two sides of the blow molding fixed mold feet 220 are respectively fixedly connected to the blow molding fixed mold base plate 210 and the blow molding carrier plate 230. When the mold is closed, the second slider 241 drives the slider 420 to move towards the inside of the mold to form the cavity of the product. When the mold is opened, the second slider 241 drives the slider 420 to move towards the outside of the mold to separate the slider from the finished product 329.

[0048] The operation process of this application includes the following steps:

[0049] Step 1: The moving mold mechanism 300 is in the first working position. The moving mold mechanism 300 moves towards the injection molding fixed mold mechanism 100 driven by the second driving mechanism, and drives the movable plate 400 to complete the mold closing action together;

[0050] Step 2: The molten material flows into the cavity of the product in the mold through the hot runner on the hot runner insert 143, and forms the product mold embryo 328 after cooling;

[0051] Step 3: The second driving mechanism drives the moving mold mechanism 300 to separate from the injection molding fixed mold mechanism 100 and complete the mold opening action. The product mold embryo 328 separates from the injection molding fixed mold mechanism 100 together with the moving mold mechanism 300, and the product mold embryo 328 is sleeved on the first moving mold core 321 and the second moving mold core 322;

[0052] Step 4: Under the action of the first driving mechanism, the moving mold mechanism 300 drives the product mold embryo 328 to rotate 180° and then runs to the second working position;

[0053] Step 5: The moving die mechanism 300 runs towards the blow molding fixed die mechanism 200 driven by the second driving mechanism, and drives the movable plate 400 to complete the mold closing action together;

[0054] Step 6: The first cylinder 311 drives the second moving die core 322 to run towards the blow molding fixed die mechanism 200, so that a gap is generated between the second moving die core 322 and the first moving die core 321, namely, a blowing port 327 is formed. External gas enters the product mold embryo 328 through the blowing channel 326 and the blowing port 327 to blow the product mold embryo 328 thin to form a finished product 329;

[0055] Step 7: The second driving mechanism drives the moving die mechanism 300 to disengage from the blow molding fixed die mechanism 200 and complete the mold opening action. The finished product 329 disengages from the injection molding fixed die mechanism 100 together with the moving die mechanism 300, and the finished product 329 is sleeved on the first moving die core 321 and the second moving die core 322;

[0056] Step 8: The second cylinder drives the retaining ring fixing plate 330 and the retaining ring 331 to run, and pushes the finished product 329, so that the finished product 329 disengages from the first moving die core 321 and the second moving die core 322, thereby obtaining the finished product 329.

[0057] It should be noted that for those of ordinary skill in the art, without departing from the concept of this application, several deformations and improvements can still be made, and these all belong to the protection scope of this application. Therefore, the protection scope of this patent application shall be subject to the appended claims.
