Description

Technical Field

[0001] This utility model relates to the field of blow molding equipment technology, and specifically to a blow-molded part structure. Background Technology

[0002] Currently, plastic products with cavities, such as plastic buckets, are often manufactured using blow molding. CN221678018U discloses an automated production and processing equipment for blow-molded products. This equipment uses a finished product output component to automatically remove the finished product from the blow-molded side panels. After the blow-molded side panels have finished producing the product, they move to the sides and open. As the side panels move and approach the ejector plate, the supporting outer plate and ejector plate move, and the ejector plate automatically removes the finished product from the blow-molded side panels. However, in actual use, after the ejector plate ejects the product, manual handling is still required to retrieve and place it for the next production process, resulting in slow product output and impacting production efficiency. Therefore, it is necessary to invent a blow-molded part ejection structure to solve these problems. Utility Model Content

[0003] The purpose of this invention is to provide a blow molding part structure to solve the problem that the part ejection process is cumbersome and affects production efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a blow-molded part structure, including an extrusion module, blow molding modules on both the left and right sides of the extrusion module, linear guide rails on the lower sides of the extrusion module and the blow molding module, two sets of blow molding dies slidably connected to the surface of the linear guide rails, and two sets of clamping assemblies fixedly connected to the opposite sides of the two sets of blow molding dies, the clamping assemblies including a support rod, a limiting sleeve, a limiting rod, a clamping plate, a limiting spring and a locking sleeve, and conveyor belts on both the left and right sides of the linear guide rails.

[0005] By adopting the above technical solution, the extrusion module is used to extrude a semi-molten plastic tube, the blow molding module is used to blow air onto the plastic tube, the blow molding die is used to clamp and fix the plastic tube, and move the plastic tube to the lower side of the blow molding module for blow molding and shaping, and the clamping assembly is used to clamp and fix the product.

[0006] Optionally, a first connecting plate is fixedly connected to the side of the blow molding die, and two sets of upper and lower fixing screws are fixedly connected to the surface of the first connecting plate, with locking nuts threaded onto the surface of the fixing screws.

[0007] By adopting the above technical solution, the first connecting plate is welded and fixed to the blow molding mold.

[0008] Optionally, a second connecting plate is fixedly connected to the end of the support rod. The surface of the second connecting plate has two sets of connecting holes, and the fixing screw is inserted into the connecting holes.

[0009] By adopting the above technical solution, the second connecting plate is placed against the side of the first connecting plate, and the fixing screw is passed through the connecting hole. Then, the locking nut is fixed to the fixing screw, thereby fixing the first connecting plate and the support rod to the side of the blow molding mold.

[0010] Optionally, the end of the support rod away from the second connecting plate is fixedly connected to two sets of limiting sleeves, and the inside of each of the two sets of limiting sleeves is slidably connected to a limiting rod, and the clamping plate is fixedly connected to the end of the limiting rod.

[0011] By adopting the above technical solution, the limiting rod slides inside the limiting sleeve, thereby driving the clamping plate to slide back and forth. Optionally, the limiting spring is sleeved on the surface of the limiting rod, and the two ends of the limiting spring abut against the clamping plate and the limiting sleeve, respectively.

[0012] By adopting the above technical solution, the limiting spring is used to support the clamping plate.

[0013] Optionally, the locking sleeve is fitted onto the end of the limiting rod surface away from the clamping plate.

[0014] By adopting the above technical solution, the locking sleeve is used to limit the position of the limiting rod.

[0015] Optionally, a connecting block is fixedly connected to the surface of the locking sleeve, and a locking screw is threadedly connected to the inside of the connecting block. One end of the locking screw abuts against the surface of the limiting rod.

[0016] By adopting the above technical solution, one end of the locking screw is pressed tightly against the surface of the limiting rod to lock and fix the locking sleeve and the limiting rod.

[0017] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0018] This invention utilizes the process of blow molding mold closing to move the side clamping plates inward, thereby clamping and fixing the product. When the blow molding mold slides to the side, the clamping plates move the product to the side as well. During the next mold opening process, the clamping plates release the product, which is then automatically placed on the surface of the conveyor belt and automatically transported to the next process, improving the convenience and efficiency of material discharge, and thus increasing product production efficiency.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model provides, for example Figures 1 to 4 The blow molding structure shown includes an extrusion module 1, with blow molding modules 11 on both the left and right sides of the extrusion module 1. A linear guide rail 2 is provided on the lower side of the extrusion module 1 and the blow molding module 11. Two sets of blow molding dies 21 are slidably connected to the surface of the linear guide rail 2. Two sets of clamping assemblies 4 are fixedly connected to the opposite sides of the two sets of blow molding dies 21. The clamping assembly 4 includes a support rod 41, a limiting sleeve 44, a limiting rod 45, a clamping plate 46, a limiting spring 47, and a locking sleeve 48. Material conveyor belts 3 are provided on both the left and right sides of the linear guide rail 2.

[0027] Among them, the extrusion module 1 is used to extrude a semi-molten plastic tube, and the blow molding module 11 is used to blow air onto the plastic tube (both the extrusion module 1 and the blow molding module 11 are existing technologies and will not be described in detail here). At the same time, after the blow molding is completed, the product will still stick to the surface of the air blowing tube.

[0028] During the blow molding process, the blow molding die 21 slides to the lower side of the extrusion module 1 in an open state. The extrusion module 1 extrudes the plastic tube into the inner side of the blow molding die 21. Then, the blow molding die 21 closes to clamp and fix the plastic tube. Next, the blow molding die 21 slides to the lower side of the blow molding module 11, and the air blowing tube in the blow molding module 11 is inserted into the inside of the plastic tube for blow molding.

[0029] After the product is blow-molded, the blow molding die 21 opens directly. At this time, the product will adhere to the outside of the air blowing tube in the blow molding module 11. After the blow molding die 21 opens, it moves to the right to the lower side of the extrusion module 1 and closes the die to clamp and fix the newly extruded plastic tube. During the die closing process, the side clamping plate 46 will move inward to clamp and fix the product. At this time, the air blowing tube in the blow molding module 11 is pulled upward. Then, when the blow molding die 21 slides back to the lower side of the blow molding module 11, the clamping plate 46 will drive the product to the upper side of the side conveyor belt 3. During the next die opening process, the clamping plate 46 will release the product and automatically place the product on the surface of the conveyor belt 3, automatically conveying the product to the next process, improving the convenience and efficiency of material discharge, and thus improving the product production efficiency.

[0030] See Figure 2 and Figure 3 The blow molding mold 21 is fixedly connected to a first connecting plate 22. The surface of the first connecting plate 22 is fixedly connected to two sets of upper and lower fixing screws 23. The surface of the fixing screws 23 is threaded with locking nuts 24. The end of the support rod 41 is fixedly connected to a second connecting plate 42. The surface of the second connecting plate 42 is provided with two sets of upper and lower connecting holes 43. The fixing screws 23 are inserted into the connecting holes 43.

[0031] During the installation of the clamping assembly 4, the second connecting plate 42 is attached to the side of the first connecting plate 22. At this time, multiple sets of fixing screws 23 are passed through the connecting holes 43, and the ends of the fixing screws 23 are locked using the locking nut 24, thereby locking and fixing the first connecting plate 22 and the second connecting plate 42, and thus fixing the clamping assembly 4 to the side of the blow molding mold 21.

[0032] See Figure 3 and Figure 4 Two sets of limiting sleeves 44 are fixedly connected to the end of the support rod 41 away from the second connecting plate 42. Limiting rods 45 are slidably connected inside the two sets of limiting sleeves 44. The clamping plate 46 is fixedly connected to the end of the limiting rod 45. The limiting spring 47 is sleeved on the surface of the limiting rod 45. The two ends of the limiting spring 47 abut against the clamping plate 46 and the limiting sleeve 44 respectively. The locking sleeve 48 is sleeved on the end of the surface of the limiting rod 45 away from the clamping plate 46. A connecting block 49 is fixedly connected to the surface of the locking sleeve 48. A locking screw 410 is threaded inside the connecting block 49. One end of the inner side of the locking screw 410 abuts against the surface of the limiting rod 45.

[0033] Specifically, during the mold closing process of the blow molding mold 21, the front and rear half molds drive the side support rods 41 to move inward. The support rods 41, in conjunction with the limiting rods 45 and the limiting springs 47, drive the clamping plates 46 on both sides to slide inward. When the blow molding mold 21 is half closed, the clamping plates 46 will contact the product surface. As the mold continues to close, the clamping plates 46 on the front and rear sides will compress the limiting springs 47 on the same side, thereby pressing the product. At this time, the air blowing pipe in the blow molding module 11 can be pulled upward. When the blow molding mold 21 is fully closed, the side clamping plates 46 will completely clamp the product. As the blow molding mold 21 slides to one side, it drives the product to slide to one side.

[0034] During the opening process of the blow molding mold 21, the side support rod 41 is driven to gradually slide outward. At this time, the clamping plate 46 will gradually relax on the product. When the mold is half open, the product will slide off the two sets of clamping plate 46 supports and land stably on the surface of the conveyor belt 3.

[0035] The working principle of this utility model is as follows: During the mold closing process of the blow molding mold 21, the side clamping plate 46 is driven to move inward, and the product is clamped and fixed by the clamping plate 46. When the blow molding mold 21 slides to the side, the product is driven to slide to the side by the clamping plate 46. During the next mold opening process, the clamping plate 46 will release the product, and then automatically place the product on the surface of the conveyor belt 3, and automatically transport the product to the next process, improving the convenience and efficiency of material discharge, thereby improving the production efficiency of the product.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
