Description

Technical Field

[0001] The present invention relates to the technical field of blow molding equipment, and in particular to intelligent blow molding equipment and a method with a flipping mechanism. Background Art

[0002] Blow molding equipment is a kind of mechanical equipment widely used in the plastic products processing industry. It is mainly used to produce plastic hollow containers of various shapes, such as bottles, cans, barrels, etc. Its basic working principle is to put plastic particles or granular raw materials into the hopper of the equipment, and then melt them through stirring and heating system. Then, the melted plastic is injected into the mold, and the plastic is expanded inside the mold and fits the mold wall through air pressure. Finally, it is cooled, solidified and demolded to obtain the finished product.

[0003] In combination with the above content, it should be explained that during the use of the blow molds inside the traditional blow molding equipment, due to the complexity of the design styles of some products, there are more vulnerable parts and areas where scraps are easily retained in the local blow mold cavities, which makes the more complex plate edge molds very prone to abnormalities, resulting in quality control problems such as abnormalities and defects in the blow molded products; traditional blow molding equipment lacks data detection of blow molded parts and blow molds, resulting in the subsequent discovery of product abnormalities, when a large number of blow molded parts with quality control problems have already been produced, resulting in material waste and affecting the normal blow molding production efficiency.

[0004] In view of the above technical defects, a solution is now proposed. Summary of the invention

[0005] The object of the present invention is to provide an intelligent blow molding equipment with a flipping mechanism. By collecting data on the blow molding processing process of the intelligent blow molding equipment, the material loss ratio and the part surface defect value are obtained, and the blow molded parts and blow molds are comprehensively supervised and analyzed during and after blow molding, that is, the collected data is compared and analyzed with the preset stored data, and relevant rating signals are obtained, and relevant components are controlled to perform compensatory operations accordingly. Therefore, it is possible to timely detect the abnormal molding of blow molded parts and the abnormal use of blow molds, prevent the continuous production of blow molded parts with abnormal molding, control the production control of blow molded parts, and flip the active main mold with abnormal use to mirror-swap, and perform linkage and quick cleaning and impurity removal, and use the active sub-mold to temporarily replace the blow mold to reduce the waste of downtime caused by the inspection and cleaning of the blow mold after the abnormality, so as to solve the problems raised.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] An intelligent blow molding device and method with a flipping mechanism, including a metal base. On the top of one side of the metal base, there is a blow molding box body. On the top of one end of the blow molding box body, there is a feeding pipe fitting. On the end face of the other end of the blow molding box body, there is a discharge port.

Inside the box body of the blow molding box body, there is a limiting mold. On the outer wall of one side of the limiting mold, there is a driving slider. On the other side of the limiting mold, there is an active main mold arranged side by side. At the bottom of the active main mold, there is a driving slide plate. On the top of the other side of the metal base, there is a cleaning box body;

[0008] On the inner wall of one end of the cleaning box body, there is a traction main frame. On the end face of the traction main frame, there is a magnetic attraction frame magnetically connected to the active main mold. On the outer wall of the other end of the cleaning box body, there is a control panel. At the bottom of the cleaning box body, there is a slag collection tank. And on the top of one end of the slag collection tank, there is an exhaust fan. Inside the slag collection tank, there is a cleaning mechanism. The cleaning mechanism includes a rotating disc and a driving air cylinder column.

[0009] Further, on the inner wall of one side of the blow molding box body, there is a recessed limiting groove. On the top of the blow molding box body, there is an air injection pipe fitting arranged side by side with the feeding pipe fitting. Below the discharge port, there is a thin rod horizontally spanning the inner walls at both ends of the blow molding box body.

[0010] Further, on the side of the driving slider, there is a telescopic air cylinder connected to the limiting mold. In the middle of the telescopic air cylinder, there is a linkage frame sleeved. On the top and bottom of the linkage frame, there is a guiding rod one.

[0011] Further, on the side of the active main mold away from the limiting mold, there is an active sub - mold. On the top and bottom of the active main mold, there are multiple groups of polygonal locking holes. On the outer wall of one end of the active main mold, there is a magnetic locking groove. At the bottom of the driving slide plate, there are multiple groups of guiding rods two. Above the driving slide plate, there is a support plate. At the bottom of the support plate, there is a lifting air cylinder connected to the driving slide plate. And on the top of the support plate, there are multiple groups of polygonal locking blocks one.

[0012] Further, in the middle of the traction main frame, there is an inner slider slidingly arranged. On the side wall of the inner slider, there is a pushing air cylinder facing the active main mold. On the side wall of the pushing air cylinder, there is a rotary air cylinder connected to the magnetic attraction frame. Above the traction main frame, there is a traction sub - frame located above the other side of the active main mold. At the bottom of the traction sub - frame, there is a traction air cylinder arm. At the bottom of the traction air cylinder arm, there are polygonal locking blocks two.

[0013] Further, on the top of one side of the cleaning box body, there is a partition wall near the active main mold. And on the plate body of the partition wall, there is an expansion air bag. At the bottom of one end of the cleaning box body, there is a slag discharge port connecting to the slag collection tank.

[0014] Furthermore, the rotating disk is sleeved on the surface of the driving cylinder column, a cleaning brush is arranged on the outer periphery of the rotating disk, convex rings are symmetrically arranged on the bottom and top of the rotating disk, side nozzles facing the movable main mold are arranged on the outer periphery of the convex ring, and an inclined nozzle facing the cleaning brush is arranged on the top of the side nozzle.

[0015] Furthermore, the control panel is internally provided with a processor, a data acquisition module, a self-checking analysis module and a signal execution module;

[0016] The data acquisition module is used to collect the material loss percentage value LSz located on the impurity remover mounting frame and the component surface defect value JMz located on the discharge port of the intelligent blow molding equipment during operation, and send the material loss percentage value LSz and the component surface defect value JMz to the self-checking analysis module through the processor;

[0017] After receiving the material loss ratio value LSz and the component surface defect value JMz, the self-checking analysis module immediately analyzes the damaged parts efficiency of the intelligent blow molding equipment. The specific analysis process is as follows: the material loss ratio value LSz and the component surface defect value JMz within the time threshold are obtained, and the damaged parts efficiency coefficient SJx is obtained through the formula, and the preset damaged parts efficiency coefficient YJx stored and entered is retrieved from the processor for comparison and analysis with the damaged parts efficiency coefficient CJx; if the damaged parts efficiency coefficient SJx ≥ the preset damaged parts efficiency YJx, it is determined that there is an abnormality in the operation of the intelligent blow molding equipment within the time threshold, and a control signal is generated, and the generated signal is sent to the signal execution module through the processor. After receiving the control signal, the signal execution module immediately controls the driving slider to work; if the damaged parts efficiency coefficient SJx < the preset damaged parts efficiency YJx, no signal is generated.

[0018] A working method of an intelligent blow molding device with a flipping mechanism, the specific steps are as follows;

[0019] Step 1: The molten raw material liquid is injected into the mold cavity of the blow molding mold along the injection pipe through the external feeding device, and the injection pipe guides the raw material liquid to form a columnar rough product in the mold cavity, and the blow molding mold is pulled to move under the gas injection pipe, and the gas injection pipe injects gas into the rough product in the mold cavity;

[0020] Step 2: further drive the blow mold to separate from the gas injection pipe and move to the area of the impurity remover mounting frame, and the impurity remover installed on the impurity remover mounting frame cuts off the top and bottom scraps of the expansion part, and a semi-finished product is obtained after completion;

[0021] Step 3: When it is detected that the blow molded part is abnormal or there is residue in the active main mold, the inner slide moves along the X-axis along the middle of the traction main frame to approach the active main mold, the push cylinder drives the magnetic suction frame to engage with the magnetic lock groove, the rotary cylinder drives the magnetic suction frame to rotate 180° along the Y-axis, and the inner slide drives the adsorbed active main mold to move along the traction main frame and embed into the partition wall;

[0022] Step 4: The exhaust fan injects air into the expansion airbag to wrap around the outer periphery of the embedded movable main mold. The driving air cylinder column drives the rotating disk to move up and down along the Z-axis to the half mold cavity area of the movable main mold. First, part of the cleaning agent is guided into the side nozzle and the inclined nozzle. The side nozzle sprays the cleaning agent on the half mold cavity, and the inclined nozzle sprays the cleaning agent on the cleaning brush. When the cleaning is about to be completed, the air flow of the exhaust fan is guided into the side nozzle and the inclined nozzle to perform pneumatic impurity removal on the half mold cavity and the cleaning brush respectively;

[0023] Step 5: After waiting for the cleaning to be completed, the inner slider drives the movable main mold to disengage from the partition wall, and keeps the movable main module facing the partition wall, so that the movable sub-mold and the limit mold are temporarily butted and closed for use.

[0024] The beneficial effects of the present invention are as follows:

[0025] 1. The present invention collects data on the processing process of blow molded parts of an intelligent blow molding device, obtains the material loss ratio and the part surface defect value, comprehensively monitors and analyzes the blow molded parts and the blow molding mold during and after blow molding, that is, compares and analyzes the collected data with the preset stored data to obtain relevant rating signals, and controls relevant components to perform compensatory operations accordingly. Therefore, it can not only detect the abnormal molding of blow molded parts and the abnormal use of the blow molding mold in time, prevent the continuous production of abnormally molded blow molded parts, control the production quality control of blow molded parts, but also perform a flip-type mirror inversion on the abnormally used movable main mold, and perform linkage and quick cleaning and impurity removal, and use the movable sub-mold to temporarily replace and piece together to form a blow molding mold, reducing the waste of downtime caused by the overhaul and cleaning after the abnormal use of the blow molding mold;

[0026] 2. The present invention uses the traction main frame to assist the cooperation of the movable main mold and the movable sub-mold to form a flip-type mirror inversion, which is convenient for quickly cleaning and statically placing the abnormally used movable main mold horizontally, and can also use the movable sub-mold and the limit mold to piece together to form a substitute blow molding mold, ensuring the overall production efficiency and effectively avoiding the high-intensity operation of the complex and vulnerable movable main mold;

[0027] 3. The present invention uses the cleaning mechanism to assist the traction main frame to cooperate, performs a soft wrapping type clamping on the outer periphery of the abnormally used movable main mold, and performs a rotating gas-liquid mixing type cleaning and repair on the inside of the half mold cavity, reducing the damage of complex and vulnerable parts in the half mold cavity of the movable main mold.

Detailed implementation manners

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0039] Embodiment 1: This embodiment is used to solve the problem that traditional blow molding equipment lacks data detection of blow molded products and blow molding molds. As a result, when abnormalities are found in the subsequent products, a large number of blow molded products with quality control problems have already been produced, causing material waste and affecting the normal blow molding production efficiency.

[0040] Please refer to Figure 1 - Figure 8 As shown in the figure, this embodiment is an intelligent blow molding equipment with a flipping mechanism, including a metal base 1. At the top of one side of the metal base 1, there is a blow molding box body 2. At the top of one end of the blow molding box body 2, there is a feeding pipe fitting 205. At the other end face of the blow molding box body 2, there is a discharge port 201. And on the inner wall of the top of the blow molding box body 2, there is an impurity removal device mounting bracket 203 close to the discharge port 201. Inside the box body of the blow molding box body 2, there is a limiting mold 4. On the outer wall of one side of the limiting mold 4, there is a driving slider 401. On the other side of the limiting mold 4, there is an active main mold 6 arranged side by side. At the bottom of the active main mold 6, there is a driving slide plate 605. On the top of the other side of the metal base 1, there is a cleaning box body 3;

[0041] On the inner wall of one end of the cleaning box body 3, there is a traction main frame 7. On the end face of the traction main frame 7, there is a magnetic attraction frame 704 magnetically connected to the active main mold 6. On the outer wall of the other end of the cleaning box body 3, there is a control panel 5. At the bottom of the cleaning box body 3, there is a slag collection tank 303. And at the top of one end of the slag collection tank 303, there is an exhaust fan 304. Inside the slag collection tank 303, there is a cleaning mechanism 8. The cleaning mechanism 8 includes a rotating disk 801 and a driving cylinder column 806;

[0042] Inside the control panel 5, there are a processor, a data acquisition module, a self-check analysis module, and a signal execution module; The data acquisition module is used to collect the material loss ratio LSz located on the impurity removal device mounting bracket 203 and the surface defect value JMz located on the discharge port 201 during the operation of the intelligent blow molding equipment, and send the material loss ratio LSz and the surface defect value JMz to the self-check analysis module through the processor; Set 10 minutes during the use of the intelligent blow molding equipment as the time threshold;

[0043] It should be noted that the material loss ratio LSz is expressed as the average value of the maximum and minimum values of the difference between the total material amount of the rough parts after blow molding and impurity removal and the injection material amount within the time threshold. The magnitude of the value of the material loss ratio LSz reflects whether there are abnormalities in the blow-molded parts and whether there is residual scrap inside the movable main mold 6. Moreover, the larger the value of the material loss ratio LSz, the more it indicates that there are abnormalities in the blow-molded parts within the time threshold and there is residual scrap inside the movable main mold 6. The surface defect value JMz of the part is expressed as whether there are defect abnormalities on the surface of the blow-molded part within the time threshold. In addition, the material loss ratio LSz is obtained from the comprehensive data acquisition of the flow sensor installed in the injection pipe fitting 205, the weighing sensor on the impurity removal device mounting rack 203, and the infrared scanning sensor on the inner wall of the blow molding box 2. The surface defect value JMz of the part is obtained from the industrial camera installed on the inner wall of the discharge port 201;

[0044] After receiving the material loss ratio LSz and the surface defect value JMz of the part, the self-check analysis module immediately analyzes the part loss efficiency of the intelligent blow molding equipment. The specific analysis process is as follows:

[0045] Obtain the material loss ratio LSz and the surface defect value JMz of the part within the time threshold. Through the formula Obtain the part loss efficiency coefficient SJx. Among them, a and b are the proportionality coefficients of the internal material loss ratio LSz and the surface defect value JMz of the part respectively, a > b > 0. SJx represents the part loss efficiency coefficient, and retrieve the preset part loss efficiency coefficient YJx stored and entered from the processor for comparison and analysis with the part loss efficiency coefficient CJx;

[0046] If the part loss efficiency coefficient SJx ≥ the preset part loss efficiency YJx, it is determined that there is an abnormality in the operation of the intelligent blow molding equipment within the time threshold, a regulation signal is generated, and the generated signal is sent to the signal execution module through the processor. After receiving the regulation signal, the signal execution module immediately controls the driving slider 401 to work;

[0047] S1: A micro-motor one and a wheel set one are arranged inside the driving slider 401. The micro-motor one drives the wheel set one to contact the inner wall of the limiting groove 202, so that the driving slider 401 moves horizontally along the X-axis inside the limiting block. A plurality of telescopic cylinders 402 slide along the surface of the guide rod one 404 through the linkage frame 403. Both ends of the guide rod one 404 are connected to the inner walls of both ends of the blow molding box 2, constituting the balance treatment during the movement of the limiting mold 4. When the limiting mold 4 needs to move away from the movable main mold 6, the telescopic cylinder 402 contracts, pulling the limiting mold 4 to move horizontally away from the movable main mold 6;

[0048] S2: A traveling cylinder connected to the inner slider 701 is provided in the traction main frame 7. The inner slider 701 is driven by the traveling cylinder to translate along the X-axis along the middle of the traction main frame 7 and approach the active main mold 6. The push cylinder 702 drives the magnetic suction frame 704 to engage with the magnetic locking groove 602, and the magnetic suction frame 704 is energized to magnetically absorb the magnetic locking groove 602. The rotary cylinder 703 drives the magnetic suction frame 704 to rotate 180° along the Y-axis, so that the positions of the active main module and the active auxiliary mold 601 are mirror-imaged. The inner slider 701 drives the absorbed active main mold 6 to move along the traction main frame 7 and embed into the partition board wall 301.

[0049] S3: The expansion airbag 302 is connected to the exhaust fan 304 through a pipe fitting. The exhaust fan 304 injects air into the expansion airbag 302 to expand the bag surface and then wrap the outer periphery of the embedded active main mold 6. The cylinder column 806 drives the rotating disk 801 to rise and fall along the Z axis to the half-side mold cavity area of the active main mold 6. A micro motor 3 connected to the cleaning brush 802 is arranged inside the rotating disk 801. The micro motor 3 drives the cleaning brush 802 to rotate. The cleaning brush 802 rotates to contact the half-side mold cavity of the active main mold 6, The half-side mold cavity is brushed, and a pipe connecting the exhaust fan 304 and the external cleaning agent container is arranged inside the convex ring 803. First, part of the cleaning agent is guided to be injected into the side nozzle 804 and the bevel nozzle 805. The side nozzle 804 sprays the cleaning agent to the half-side mold cavity, and the bevel nozzle 805 sprays the cleaning agent to the cleaning brush 802. When the cleaning is about to be completed, the airflow of the exhaust fan 304 is guided to be injected into the side nozzle 804 and the bevel nozzle 805, and the half-side mold cavity and the cleaning brush 802 are pneumatically cleaned;

[0050] S4: After waiting for the cleaning to be completed, the inner slider 701 drives the movable main mold 6 to separate from the partition wall 301, and keeps the movable main mold toward the partition wall 301, so that the movable auxiliary mold 601 and the limiting mold 4 are temporarily docked and closed for use;

[0051] If the loss component efficiency coefficient SJx is less than the preset loss component efficiency YJx, no signal is generated.

[0052] Embodiment 2: This embodiment is used to solve the problem that during use, the blow molding molds inside traditional blow molding equipment are affected by the complexity of some product design styles, resulting in more vulnerable parts and areas where scraps are easily retained in the local blow molding mold cavity, which makes the more complex plate edge molds very prone to anomalies, resulting in quality control problems such as anomalies and defects in the finished blow molding products.

[0053] See also Figure 1 - Figure 7As shown in the figure, this embodiment is an intelligent blow molding device with a flipping mechanism. A limiting groove 202 is recessed on the inner wall of one side of the blow molding box body 2. An air injection pipe fitting 204 parallel to the feeding pipe fitting 205 is arranged on the top of the blow molding box body 2. A thin rod 206 spanning across the inner walls at both ends of the blow molding box body 2 is arranged below the discharge port 201. The limiting die 4 and the movable main die 6 are temporarily closed to form a blow molding die. The molten raw material liquid is guided along the feeding pipe fitting 205 by an external feeding device, and the feeding pipe fitting 205 guides the raw material liquid into the cavity of the blow molding die, forming a columnar rough product in the cavity. The feeding pipe fitting 205 pauses feeding.

[0054] Please refer to Figure 2 - Figure 4 As shown in the figure, the driving slider 401 and the driving slide plate 605 are started synchronously, and the blow molding die is towed to move below the air injection pipe fitting 204. The air injection pipe fitting 204 injects air into the rough product in the cavity to blow mold it, prompting the rough product to expand under the increasing air pressure and adhere to the inner wall of the cavity, forming an expanded part. The blow molding die is further driven to move away from the air injection pipe fitting 204 and move to the area of the impurity removal device mounting frame 203. The impurity removal device mounted on the impurity removal device mounting frame 203 cuts off the top and bottom corner materials of the expanded part. After completion, a semi-finished product is obtained. The driving slider 401 drives the limiting die 4 to separate from the movable main die 6, and the semi-finished product is taken out from the movable main die 6 by the picking robotic arm outside the discharge port 201.

[0055] A telescopic cylinder 402 connected to the limiting die 4 is arranged on the side of the driving slider 401. A micro motor two and a wheel set two in transmission connection with the guide rod two 604 are arranged at the bottom of the driving slide plate 605. The micro motor two and the wheel set two contact the guide rod two 604 and tow the driving slide plate 605 to move horizontally along the X axis. The bottom of one side of the driving slide plate 605 is slidably sleeved on the thin rod 206. Both ends of the thin rod 206 are connected to the inner walls at both ends of the blow molding box body 2. Both ends of the guide rod two 604 are connected to the inner walls at both ends of the cleaning box body 3. A linkage frame 403 is sleeved in the middle of the telescopic cylinder 402. Guide rods one 404 are arranged at the top and bottom of the linkage frame 403.

[0056] Please refer to Figure 4 - Figure 5 As shown in the figure, the top of the driving slide plate 605 pushes the support plate 607 to lift and lower along the Z axis through the lifting cylinder 606, prompting the multi-sided lock block one 608 to be clamped and limited with the multi-sided lock holes 603 at the bottom of the movable main die 6 and the movable sub-die 601. When the magnetic attraction frame 704 is connected to the magnetic lock groove 602, the lifting cylinder 606 drives the support plate 607 to slide down, and the multi-sided lock block one 608 disengages from the multi-sided lock hole 603 at the bottom of the movable main die 6, waiting for the magnetic attraction frame 704 to flip the movable main die 6 and then slide up again to lift and support the movable main die 6. When the multi-sided lock block two 707 is connected to the multi-sided lock hole 603 at the top of the movable main die 6, the multi-sided lock block one 608 disengages from the multi-sided lock hole 603 at the bottom of the movable main die 6 again.

[0057] On one side of the movable main mold 6 away from the limit mold 4, there is a movable sub-mold 601. On the top and bottom of the movable main mold 6, there are multiple groups of polygonal lock holes 603. On the outer wall of one end of the movable main mold 6, there is a magnetic lock groove 602. At the bottom of the driving slide plate 605, there are multiple groups of guide rods two 604. Above the driving slide plate 605, there is a support plate 607. At the bottom of the support plate 607, there is a lifting cylinder 606 connected to the driving slide plate 605, and on the top of the support plate 607, there are multiple groups of polygonal lock blocks one 608;

[0058] Please refer to Figure 4 As shown in the figure, an inner slider 701 is slidably arranged in the middle of the traction main frame 7. On the side wall of the inner slider 701, there is a pushing cylinder 702 facing the movable main mold 6. On the side wall of the pushing cylinder 702, there is a rotary cylinder 703 connected to the magnetic attraction frame 704. Above the traction main frame 7, there is a traction sub-frame 705 located above the other side of the movable main mold 6. At the bottom of the traction sub-frame 705, there is a traction cylinder arm 706. At the bottom of the traction cylinder arm 706, there are polygonal lock blocks two 707;

[0059] On one side at the top of the cleaning box body 3, there is a partition wall 301 close to the movable main mold 6, and on the plate body of the partition wall 301, there is an expansion airbag 302. At one end at the bottom of the cleaning box body 3, there is a slag discharge port 305 connected to the slag collection tank 303. The cleaned fallen residues and cleaning agents are collected in the slag collection tank 303, waiting to open the slag discharge port 305 regularly to recycle the collected residues and cleaning agents. The cleaned movable main mold 6 is statically waiting, and the movable sub-mold 601 is used to replace the operation;

[0060] The rotating disk 801 is sleeved on the surface of the driving cylinder column 806. On the outer periphery of the rotating disk 801, there is a cleaning brush 802. At the bottom and top of the rotating disk 801, there are convex rings 803 symmetrically arranged. On the outer periphery of the convex rings 803, there are side nozzles 804 facing the movable main mold 6, and on the top of the side nozzles 804, there are inclined nozzles 805 facing the cleaning brush 802.

[0061] Combining Embodiment 1 and Embodiment 2, it is thus possible to promptly detect abnormal plastic part molding and abnormal use of the blow molding mold, prevent the continuous production of blow molded parts with molding abnormalities, control the quality control of blow molded parts production, and at the same time, perform a flip-type mirror swapping on the movable main mold 6 with abnormal use, as well as carry out a quick and linked cleaning and impurity removal, use the movable sub-mold 601 to temporarily replace and piece together to form a blow molding mold, reducing the waste of downtime caused by the repair and cleaning after the blow molding mold is abnormal.

4. A working method of an intelligent blow molding device with a flipping mechanism, which is used for the intelligent blow molding device with a flipping mechanism according to any one of claims 1-3, characterized in that, The specific steps are as follows; Step 1: The molten raw material liquid is guided along the injection pipe fitting (205) through an external feeding device. The injection pipe fitting (205) guides the raw material liquid into the mold cavity of the blow molding mold, forming a columnar rough product in the mold cavity. The blow molding mold is pulled to move below the air injection pipe fitting (204), and the air injection pipe fitting (204) injects air into the rough product in the mold cavity for blow molding. Step 2: Further drive the blow molding mold to move away from the air injection pipe fitting (204) and move to the area of the impurity removal device mounting frame (203). The impurity removal device installed on the impurity removal device mounting frame (203) cuts off the top and bottom corner materials of the expanded part, and a semi-finished product is obtained after completion. Step 3: When an abnormality is detected in the blow-molded part or there is a residue in the movable main mold (6), the inner slider (701) translates along the X-axis near the movable main mold (6) in the middle of the traction main frame (7), the pushing cylinder (702) drives the magnetic adsorption frame (704) to be clamped with the magnetic locking groove (602), and the rotary cylinder (703) drives the magnetic adsorption frame (704) to rotate 180° along the Y-axis. The inner slider (701) drives the adsorbed movable main mold (6) to move along the traction main frame (7) and embed into the partition wall (301); Step 4: The exhaust fan (304) injects air into the inside of the expansion airbag (302) to attach and wrap the outer periphery of the embedded movable main mold (6). The driving cylinder column (806) drives the rotary disk (801) to lift and lower along the Z-axis to the half mold cavity area of the movable main mold (6). First, part of the cleaning agent is guided into the side nozzle (804) and the inclined surface nozzle (805). The side nozzle (804) sprays the cleaning agent on the half mold cavity, and the inclined surface nozzle (805) sprays the cleaning agent on the cleaning brush (802). When the cleaning is about to be completed, the air flow of the exhaust fan (304) is guided into the side nozzle (804) and the inclined surface nozzle (805) to perform pneumatic impurity removal on the half mold cavity and the cleaning brush (802) respectively; Step 5: After waiting for the cleaning to be completed, the inner slider (701) drives the movable main mold (6) to disengage from the partition wall (301), and keeps the movable main module facing the partition wall (301) so that the movable sub-mold (601) is temporarily butted and closed with the limit mold (4) for use.
