[0014] Furthermore, both of the two intelligent sensing devices are intelligent inductive proximity sensors.

[0015] At least one of the above technical solutions adopted in the embodiments of the present invention can achieve the following beneficial effects:

[0016] First, when the intelligent sensor device detects that the product has not fallen, the lifting panel on the output end of the lifting hydraulic cylinder is driven to move upward, thereby driving the spraying and demoulding integrated device to move upward, and driving the demoulding rod in the spraying and demoulding integrated device to make the position higher than the blow mold. After reaching the required height, the lifting hydraulic cylinder stops running, and then the lifting seat on the output end of the side push hydraulic cylinder is driven to move toward the center of the blow mold through the operation of the side push hydraulic cylinder, and the push hydraulic cylinder is synchronously driven to drive the spraying and demoulding integrated device to move forward and backward. Movement, and finally, through the coordinated operation of the front and rear pushing devices and the side pushing device, the demoulding rod is moved to the top of the blow mold, that is, just above the center of the bottle mouth of the blow-molded product that has not fallen, and then the demoulding rod is driven downward by the operation of the lifting hydraulic cylinder, so that the demoulding rod just enters the blow-molded product from the bottle mouth of the blow-molded product, and then, the demoulding rod in the spraying and demoulding integrated device is driven to move forward by the operation of the pushing hydraulic cylinder. At this time, the completed blow-molded product is pushed out of the blow mold by the driving force and finally falls, thereby realizing the demoulding operation of the blow-molded product.

[0017] Secondly, the device is highly flexible and precise, and can adapt to blow molds of various complex shapes and structures. It can be personalized according to the specific blow mold blow mold product size, shape and spraying requirements to ensure the consistency and stability of the spraying quality. It can significantly improve production efficiency, reduce the labor intensity and errors of manual operation, and is suitable for large-scale production.

[0018] Thirdly, the device can accurately align the pattern according to the shape and pattern inside the blow mold to evenly spray the release agent. When the spray nozzle evenly sprays the release agent, it first sprays the release agent at the bottle mouth of the blow molded product. The bottle mouth is a threaded groove with a threaded state and the size is generally narrow. Therefore, the spray end of the spray nozzle needs to be adjusted. The gear in the spray adjustment device on the integrated spray and demoulding device is driven to move to a meshing state with the corresponding rack through the cooperation of the side push device, the lifting device and the front and rear push devices. In the initial state of the spray nozzle, the first spray hole position and the third spray hole position are connected to the spray auxiliary head for spraying. This state is to maximize the maximum range. For spraying, after the gear is meshed with the rack, the gear in the spraying adjustment device on the spray-demolding integrated device is driven downward by the lifting device, and the gear is meshed with the rack and rotated thirty degrees with the assistance of the gear, so that the spray nozzle is connected with the spray auxiliary head through the third spray hole to spray, that is, the spray nozzle can only spray the release agent through the third spray hole, and the third spray hole is the center position of the spray nozzle. Therefore, spraying is used for some special bottle-like surfaces, even with relatively replicated patterns such as engraved patterns, threads, and smaller locations. This not only can accurately and evenly spray the release agent, but also can reduce the waste of the release agent and avoid the release agent being sprayed to insignificant locations to cause waste of resources.

DETAILED DESCRIPTION

There are two intelligent sensing devices 12, and the two intelligent sensing devices 12 are respectively arranged on the corresponding spraying and demoulding integrated devices 6 and facing the blow mold 1.

[0040] During the process of integrated injection-blow blow molding, after the injection and blowing of the required product is completed, the device can detect whether the completed product has been successfully demolded, so as to accurately carry out the injection and blowing operation of the next product. After the product is detected to have fallen, the operation can be continued. If it is detected that the product has not fallen, the product is smoothly demolded by cooperating with the pushing device 5, the lifting device 4, the front and rear pushing device 5, the integrated spraying and demolding device 6, the angle adjustment device 7 and the spraying adjustment device 8. After the product is demolded, the demolding agent is evenly sprayed on the inside of the blow mold 1, so as to help the next product to be effectively and smoothly demolded after the operation is completed.

[0041] The side push device 3, lifting device 4, front and rear push device 5, spraying and demoulding integrated device 6, angle adjustment device 7 and spraying adjustment device 8 of the device can be connected correspondingly through the intelligent system, and the operation can be performed in real time according to the background.

[0042] Preferably, the two mold opening and closing devices 2 each include a fixed seat 21, an opening and closing seat 22, an opening and closing frame 23, an opening and closing hydraulic cylinder 24 and a sliding rod 25. The fixed seat 21 is provided with a sliding groove 26. The opening and closing seat 22 is arranged on the fixed seat 21. The opening and closing frame 23 is arranged on the fixed seat 21. The opening and closing hydraulic cylinder 24 is arranged on the opening and closing seat 22 and the output end of the opening and closing hydraulic cylinder 24 passes through the opening and closing frame 23. Two sliding rods 25 are provided, and the two sliding rods 25 are symmetrically arranged at the side ends of the fixed seat 21. The blow mold 1 is sleeved on the two sliding rods 25 and is arranged for sliding fit. The output end of the opening and closing hydraulic cylinder 24 is connected to the outer side of the blow mold 1.

[0043] The injection-blowing integrated blow molding device is mainly composed of an injection system, a parison mold, a blow molding mold 1, an opening and closing mold mechanism, and a demoulding mechanism. The injection system is used to melt the plastic raw material and inject the parison. The parison mold is a key component for forming the parison. The blow molding mold 1 is a mold for blowing the parison into the shape of the final product. The opening and closing mold mechanism controls the opening and closing action of the blow molding mold 1. The demoulding mechanism is used for rapid demoulding of the product. When the required product is completed after injection and blowing, the blow molding mold 1 is driven to realize the opening movement through the synchronous operation of the two opening and closing hydraulic cylinders 24, and the finished blow molding product is demoulded. Under normal operating conditions, that is, when the demoulding agent inside the blow molding mold 1 is good, the finished blow molding product will fall directly after the blow molding mold 1 is opened. However, due to the shape of the product and the lack of demoulding agent inside the blow molding mold 1, the finished product will have a large friction and a large contact range with the blow molding mold 1. Therefore, there is a problem of not falling after the blow molding mold 1 is opened;

[0044] The common type of release agent for this device is silicone release agent, the main component of which is organic silicon compounds, such as silicone oil, silicone rubber, etc. It has excellent demolding performance and can form a very thin and uniform isolation film on the surface of the mold. The surface tension of this film is very low, making it easy for the plastic product to be separated from the mold after molding. For example, when producing high-precision medical plastic syringes, silicone release agents can effectively prevent the adhesion of plastics to the mold, ensuring the surface quality and dimensional accuracy of the product. Silicone release agents also have good thermal stability and can maintain their demolding performance at higher temperatures. Because the mold temperature may be high during the injection-blow molding process, especially during continuous production, silicone release agents can withstand certain temperature changes without failure. In the injection-blow molding production of food packaging or medical products, the safety of the release agent needs to be considered. For example, select a release agent that meets food grade or medical grade standards. There are some silicone release agents specifically used in the food and medical industries. After strict safety testing, it can be ensured that the product meets relevant hygiene standards.

[0045] During the blow molding process, after the injection and blowing of the required product is completed, the blow molding mold 1 is first driven to open through the synchronous operation of the two opening and closing hydraulic cylinders 24. When the blow molding mold 1 is opened, the corresponding intelligent sensor device on the side of the blow molding mold 1 detects whether the product has fallen. If the corresponding intelligent sensor device detects the product, it proves that the product has not fallen. Therefore, at this time, auxiliary assistance is needed to complete the demolding operation of the blow-molded product. If the corresponding intelligent sensor device does not detect the product, it proves that the product has been dropped, so that the blow molding operation of the next product can be carried out directly.

[0046] Preferably, the two side thrust devices 3 each include a side thrust frame 31 and a side thrust hydraulic cylinder 32, the side thrust frame 31 is arranged on one side of the fixed seat 21, the side thrust hydraulic cylinder 32 is arranged on the side thrust frame 31, the two lifting devices 4 each include a lifting seat 41, a lifting hydraulic cylinder 42, a lifting frame 43 and a lifting panel 44, the lifting seat 41 is arranged in the corresponding sliding groove 26 and is arranged for sliding cooperation, the lifting hydraulic cylinder 42 is arranged inside the lifting seat 41, the lifting frame 43 is arranged on the lifting seat 41, and the lifting hydraulic cylinder 4 The output end of the lifting panel 2 passes through the lifting frame 43, the lifting panel 44 is arranged on the output end of the lifting hydraulic cylinder 42, the two front and rear pushing devices 5 each include a pushing seat 51, a pushing hydraulic cylinder 52 and a pushing frame 53, the lifting panel 44 is provided with a slide groove 45, the pushing seat 51 is arranged on the side end of the lifting panel 44, the pushing frame 53 is arranged on the lifting panel 44, the pushing hydraulic cylinder 52 is arranged on the pushing seat 51, and the output end of the pushing hydraulic cylinder 52 passes through the pushing frame 53 and is connected to the corresponding spraying and demoulding integrated device 6;

[0047] When the intelligent sensor device detects that the product has not fallen, the lifting panel 44 on the output end of the lifting hydraulic cylinder 42 is driven to move upward, thereby driving the spraying and demoulding integrated device 6 to move upward, and driving the demoulding rod 66 in the spraying and demoulding integrated device 6 to make the position higher than the blow mold 1. After reaching the required height, the lifting hydraulic cylinder 42 stops running, and then the lifting seat 41 on the output end of the side push hydraulic cylinder 32 is driven to move toward the center of the blow mold 1 through the operation of the side push hydraulic cylinder 32, and the pushing hydraulic cylinder 52 is synchronously operated to drive the spraying and demoulding integrated device 6 to move forward and backward. Finally, through the coordinated operation of the front and rear pushing devices 5 and the side push device 3, the demoulding rod 66 is moved to the top of the blow mold 1, that is, the top of the center of the bottle mouth of the blow molded product that has not fallen. Then, the demoulding rod 66 is driven to move downward through the operation of the lifting hydraulic cylinder 42, so that the demoulding rod 66 just enters the blow molded product from the bottle mouth of the blow molded product. Figure 7 and Fig.15 In the state shown, the demoulding rod 66 in the spraying and demoulding integrated device 6 is driven to move forward by pushing the hydraulic cylinder 52, and at this time, the completed blow-molded product is pushed out from the inside of the blow-molding mold 1 by the driving force and finally falls, thereby realizing the demoulding operation of the blow-molded product;

[0048] At present, the blow molding mold 1 of the injection-blowing integrated type cannot fall after the operation is completed. The reasons may be as follows: first, when the weight of the product blown inside the blow molding mold 1 is large and the center of gravity is unevenly distributed, it may cause a large friction or stagnation force between the blow molding mold 1 and the blow molding product after the operation is completed, so that it cannot fall smoothly; second, the mold release agent inside the blow molding mold 1 is insufficient and uneven, so that there is a large friction or stagnation force between the blow molding product and the blow molding mold 1. The blow molding mold 1 of the device is divided into two halves. Therefore, there is no problem that the blow molding product inside the blow molding mold 1 When the product itself is heavy and the center of gravity is unevenly distributed, it may not be able to fall. That is to say, there is a large friction between the blow mold 1 and the blow molded product, which is a major problem that the blow molded product cannot fall after the blow mold 1 is opened. In order to solve the friction between the blow mold 1 and the blow molded product, it is necessary to evenly spray the shape of the blow molded product inside the blow mold 1 with a release agent, and after the blow molded product is completed, reduce the contact surface between the blow molded product and the blow mold 1 to reduce friction, achieve normal falling of the blow molded product, and thus speed up the processing efficiency of the blow molded product.

[0049] Preferably, the two integrated spraying and demoulding devices 6 each include a spray box 61, a spray pipeline 62, a connecting pipe 63, a spray nozzle 64, a connecting block 65 and a demoulding rod 66, the spray box 61 is slidably arranged in the corresponding slide groove 45, a pump for spraying the demoulding agent in the spray box 61 is arranged inside the spray box 61, the head end of the spray pipeline 62 is connected to the spray box 61, the connecting pipe 63 is connected to the end of the spray pipeline 62 and is rotatably connected to the end of the spray pipeline 62, the spray nozzle 64 is connected and arranged on the connecting pipe 63, the spray nozzle 64 is provided with a spray hole 67, the connecting block 65 is arranged on the spray pipeline 62, and the demoulding rod 66 is arranged on the connecting block 65;

[0050] When the intelligent sensor device detects that the product has not fallen, it means that there is a large friction between the blow mold 1 and the blow molded product. After the blow molded product is placed and pushed to fall, the shape space inside the blow mold 1 is evenly sprayed with a release agent to reduce the friction between the blow mold 1 and the blow molded product, so that the blow molded product can fall normally. After the blow molded product is pushed and demolded by the auxiliary, data programming can be performed according to the shape inside the blow mold 1, so that the side push device 3, the lifting device 4, the front and rear push device 5, the spraying and demolding integrated device 6, the angle adjustment The device 7 and the spray adjustment device 8 move relative to each other through data programming to achieve uniform release agent spraying operation. The uniform release agent spraying step is firstly to drive the spray demolding integrated device 6 to move left and right and front and back through the cooperation of the side push device 3, the lifting device 4 and the front and back pushing device 5, so that the spray nozzle 64 in the spray demolding integrated device 6 is located on the inner side above the blow mold 1 where the release agent needs to be sprayed and the spray nozzle 64 faces the inside of the blow mold 1, and then the side push device 3, the lifting device 4 and the front and back pushing device 5 move according to the programmed data through the space of the internal shape of the blow mold 1, and the programmed data is consistent with the data programmed by the traditional CNC lathe, according to the blow mold The shape of the inside of the blow mold 1 moves from top to bottom and from left to right, thereby driving the spray nozzle 64 to move according to the shape of the inside of the blow mold 1. During the movement of the spray nozzle 64, the pump inside the spray box 61 is operated to allow the release agent inside the spray box 61 to pass through the spray pipeline 62 and the connecting pipe 63, and finally be sprayed out through the spray nozzle 64, so that it is just sprayed into the inside of the blow mold 1, achieving the effect of uniform spraying of the release agent. During the spraying of the release agent by the spray nozzle 64, the angle can be adjusted a little according to the shape of the inside of the blow mold, so that the spraying effect of the spray nozzle 64 is better.

[0053] Inductive proximity sensors mainly use the principle of electromagnetic induction. When a plastic product approaches the induction coil of the sensor, the inductance of the coil will change. For non-magnetic materials such as most plastic products, it works by detecting the change in inductance of the induction coil under the influence of the plastic product. When the plastic product enters the induction magnetic field area, the distribution of the magnetic field changes, which causes the inductance to change, triggering the sensor to output a signal. Application scenarios and advantages: In injection molding or blow molding production equipment, it is used to detect whether the plastic product is successfully demolded from the mold and enters the conveying system. For example, in the production process of plastic toys, the inductive proximity sensor can be installed near the mold outlet. When the toy product is demolded and approaches, the sensor detects the change in inductance, sends a signal, and starts the conveying device to transport the toy away. Its advantages are high precision and strong anti-interference ability, especially for environments with certain metal impurities or electromagnetic interference, it can work relatively stably;

[0054] The core part of the blow molding mold 1 directly determines the external shape of the product. The shape of the cavity is completely consistent with the appearance of the final blow-molded product, and its dimensional accuracy is very high. For example, when producing plastic bottles, the contour of the cavity determines the shape of the bottle, including the curvature of the bottle body, the shape and height of the bottleneck, etc. When designing and manufacturing the cavity, it is necessary to consider the product's use function, appearance requirements and the characteristics of the blow molding process. Since the injection-blow integrated blow molding products are generally bottle-shaped plastic products, and the bottle-shaped surfaces have patterns, threads and sliding grooves, etc., some special bottle-shaped surfaces even have more complex patterns such as engraved lines. , and these blow-molded products undoubtedly have a wider contact area with the blow-molding mold 1, so the friction between the blow-molded products and the blow-molding mold 1 will be greater, and after the blow-molding product is blown, after the blow-molding mold 1 is opened, the blow-molding mold 1 will not fall off. At this time, the device can accurately align the pattern according to the shape and pattern inside the blow-molding mold 1 to evenly spray the release agent. In the process of evenly spraying the release agent, the spray nozzle 64 first sprays the release agent at the bottle mouth of the blow-molded product. The bottle mouth position is a threaded groove in a threaded state and the size is generally narrow, so the spray nozzle needs to be The spraying end of the head 64 is adjusted, and the gear 82 in the spraying adjustment device 8 on the spray-stripping integrated device 6 is driven to move to a meshing state with the corresponding rack 83 through the cooperation of the side push device 3, the lifting device 4 and the front and rear pushing device 5. In the initial state of the spray nozzle 64, the first spray hole position 681 and the third spray hole position 683 are connected with the spray auxiliary head 81 to spray. This state is used for spraying in the maximum range. After the gear 82 is engaged with the rack 83, the gear 82 in the spraying adjustment device 8 on the spray-stripping integrated device 6 is driven by the lifting device 4 to move downward, and the gear 82 is connected to the spray auxiliary head 81 through the lifting device 4. The spray nozzle 64 is meshed with the rack 83 and rotated 30 degrees with the assistance of the cooperation, so that the spray nozzle 64 is connected with the spray auxiliary head 81 through the third spray hole 683 to spray, that is, the spray nozzle 64 can only spray the release agent through the third spray hole 683, and the third spray hole 683 is the center position of the spray nozzle 64, so that it can be used for spraying on some special bottle-like surfaces or even with more complex patterns such as carved patterns, threads and smaller sizes. In this way, the release agent can be sprayed accurately and evenly, and the waste of the release agent can be reduced, and the waste of resources caused by the release agent being sprayed to insignificant positions can be avoided. When the spray nozzle 64 is readjusted, the gear 82 in the spray adjustment device 8 on the spray demoulding integrated device 6 can be driven to move to a meshing state with the corresponding rack 83 through the cooperation of the side push device 3, the lifting device 4 and the front and rear pushing device 5. The rack 83 is driven by the lifting device 4 to move upward or downward to adjust the spray nozzle 64 to the required state to match the shape of the blow molded product. According to the fineness and width changes of the pattern or thread on the product,The use of a center hole nozzle is an effective strategy for rapid demolding of an integrated injection-blow molding device. For example, when the product has fine threads, the nozzle is adjusted to a central independent state so that the mold release agent is sprayed accurately into the thread groove in the form of a fine mist, thereby avoiding waste and accumulation of mold release agent caused by excessive spraying, and ensuring that both raised and recessed areas of the pattern are sprayed evenly. The spray nozzle 64 of this device is adjusted to automatic control, and is programmed to connect to the automatic spraying system according to the product shape, and the program is adjusted according to the product parameter instructions. For products with complex patterns and threads, a multi-nozzle combination module is designed, and each small nozzle has independent opening and closing and angle adjustment functions. For example, when spraying plastic products with spiral patterns, the spray nozzle 64 is tilted at an angle to the side wall of the thread, which can also The spray nozzle 64 can be used to focus on the flat part of the pattern and spray vertically. According to the demoulding requirements of different parts of the product, the corresponding spray nozzle 64 can be accurately activated through the control system to achieve segmented and multi-layered precise spraying, so that the demoulding agent can be evenly attached to the surface of complex patterns. The layered spraying process is formulated according to the product pattern and thread depth. For deeper threads, the first layer of primer is first applied with a low-flow, high-atomization demoulding agent to allow the demoulding agent to fully infiltrate the bottom of the thread, and then the flow rate is increased layer by layer, and the angle of the spray nozzle 64 is adjusted to cover the upper part of the thread and the surrounding patterns. The interval time of each layer of spraying is precisely controlled to facilitate the uniform penetration and adhesion of the demoulding agent, and avoid the flow and accumulation of the demoulding agent due to a thick coating, which affects the product precision and subsequent molding quality.
