Description

Technical Field

[0001] This utility model relates to the field of blow molding technology, specifically to a mold for a stretchable sauce bottle. Background Technology

[0002] Blow molding, also known as hollow blow molding, is a rapidly developing plastic processing method. During World War II, blow molding was first used to produce low-density polyethylene bottles. Suitable plastics for blow molding include polyethylene, polyvinyl chloride, polypropylene, and polyester. The resulting hollow containers are widely used as industrial packaging containers. Based on the preform manufacturing method, blow molding can be divided into extrusion blow molding and injection blow molding. Newer methods include multilayer blow molding and stretch blow molding. Currently, plastic products with cavities, such as plastic buckets, are often manufactured using blow molding. In the blow molding process, the raw material is first pretreated and then fed into a pressure tube for melting. The molten material is then extruded into a plastic tube and fixed inside the mold. The tube is then blow-molded using a blow molding module, and finally, the cooled and shaped product is trimmed.

[0003] Most existing blow molding molds consist of two halves, which enclose the plastic tube inside for blow molding. Since some waste is generated during the blow molding process, the blow molding mold needs to be opened to remove the product for repair. The repair process is quite cumbersome and affects the production efficiency.

[0004] Therefore, it is necessary to invent a mold for a stretchable sauce bottle to solve the above problems. Utility Model Content

To achieve the above objective, this utility model provides the following technical solution: a mold for a stretchable sauce bottle, including a first guide rail, a first support plate that can slide left and right on the upper side of the first guide rail, an mounting plate fixedly connected to the right end of the first guide rail, a first hydraulic cylinder fixedly mounted on the side of the mounting plate, the left end of the piston rod of the first hydraulic cylinder being fixedly connected to the right end of the first support plate, and a blow molding assembly provided on the upper side of the first support plate, the blow molding assembly including a second hydraulic cylinder, a bottom mold, a first cylinder, a second support plate, a top mold, a second cylinder, a fixing frame, a side mold, and a third cylinder.

[0006] By adopting the above technical solution, the upper side of the first guide rail is provided with an extrusion module, a blow molding module and a cutting module from right to left. The mold is divided into a bottom mold, two sets of side molds and two sets of top molds. The five half molds are closed to clamp and fix the plastic tube extruded by the extrusion module, and then moved to the lower side of the blow molding module for blow molding. After blow molding is completed, the two sets of top molds open to both sides to expose the waste material on the outside. At this time, the fixing frame and the two sets of side molds are moved to the lower side of the cutting module, and the product waste is directly cut by the cutting module, which effectively improves the product production efficiency.

[0010] Optionally, the second hydraulic cylinder is fixedly installed at the right end of the first support plate, and the left end of the piston rod in the second hydraulic cylinder is fixedly connected to the right end of the fixed frame.

[0011] By adopting the above technical solution, the second hydraulic cylinder is used to push the fixed frame to slide left and right, thereby adjusting the position of the side mold.

[0012] Optionally, the bottom mold is located at the middle position on the upper side of the first support plate, and two sets of first positioning rods are fixedly connected to the lower surface of the bottom mold. Two sets of first positioning sleeves are fixedly connected to the lower surface of the first support plate. The first positioning rods are slidably connected to the first positioning sleeves. The first cylinder is fixedly installed at the middle position on the lower surface of the first support plate, and the piston rod in the first cylinder is fixedly connected to the lower surface of the bottom mold.

The five half molds clamp and fix the plastic tube extruded by the extrusion module, and move it to the lower side of the blow molding module for blow molding. After blow molding is completed, the two sets of top molds open to the sides and the bottom mold opens downwards to expose the waste material to the outside. At this time, the fixing frame and the two sets of side molds are moved to the lower side of the cutting module, and the product waste is directly cut by the cutting module, which effectively improves the product production efficiency.

[0022] 2. This utility model fixes the bottle body by opening the top and bottom molds and relying only on two sets of side molds. After cutting, the fixing frame and side molds are moved to the right, and the two sets of side molds are opened to both sides. At this time, the two sets of side molds only need to open a small distance to both sides, and the bottle body will slide between the two sets of side molds. This realizes material feeding during the side mold reset process, thereby saving material feeding time and further improving the production efficiency of the product. Attached Figure Description

Detailed Implementation

[0033] 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.

[0034] This utility model provides, for example Figures 1 to 8The mold for a stretchable sauce bottle shown includes a first guide rail 1. A first support plate 2 that can slide left and right is provided on the upper side of the first guide rail 1. A first slider 22 is fixedly connected to the lower surface of the first support plate 2. The first slider 22 is slidably connected to the first guide rail 1. A mounting plate 11 is fixedly connected to the right end of the first guide rail 1. A first hydraulic cylinder 12 is fixedly mounted on the side of the mounting plate 11. The left end of the piston rod in the first hydraulic cylinder 12 is fixedly connected to the right end of the first support plate 2. A blow molding assembly is provided on the upper side of the first support plate 2. The blow molding assembly includes a second hydraulic cylinder 24, a bottom mold 25, a first cylinder 26, a second support plate 3, a top mold 31, a second cylinder 32, a fixing frame 4, a side mold 42, and a third cylinder 43. The first slider 22 slides left and right on the surface of the first guide rail 1 to limit the position of the first support plate 2. Simultaneously, it works with the first hydraulic cylinder 12 to adjust the left and right position of the first support plate 2. During the feeding process, the first hydraulic cylinder 12 moves the blow molding assembly to the lower side of the right extrusion module. At this time, the bottom mold 25, top mold 31, and side mold 42 cooperate to clamp and fix the plastic tube. Then, the first hydraulic cylinder 12 moves the blow molding assembly to the lower side of the blow molding module for blow molding. After blow molding is completed, the first cylinder 26 and the second cylinder 32 cooperate to respectively move the bottom mold 25... When the top mold 31 is opened, the bottle body 5 is fixed only by the two sets of side molds 42. Then, the second hydraulic cylinder 24 pushes the fixing frame 4, the side molds 42 and the bottle body 5 to the left, moving them to the lower side of the cutting module. The cutting module is used to cut the waste block 51 at the upper end of the bottle body 5. After the cutting is completed, the second hydraulic cylinder 24 directly moves the fixing frame 4 and the side molds 42 to the right, and at the same time opens the third cylinder 43. Since the bottle body 5 is only held by the side molds 42, the bottle body 5 can fall when the side molds 42 are opened a small distance, improving product production efficiency.

[0035] See Figures 2 to 4 The bottom mold 25 is located at the middle of the upper side of the first support plate 2. The lower surface of the bottom mold 25 is fixedly connected with two sets of first positioning rods 28 on the left and right. The lower surface of the first support plate 2 is fixedly connected with two sets of first positioning sleeves 27. The first positioning rods 28 and the first positioning sleeves 27 are slidably connected. The first cylinder 26 is fixedly installed at the middle of the lower surface of the first support plate 2. The piston rod in the first cylinder 26 is fixedly connected to the lower surface of the bottom mold 25. The front and rear sides of the first support plate 2 are fixedly connected with second support plates 3 in the shape of "7". The top mold 31 is provided with two sets. The opposite sides of the two sets of top molds 31 are fixedly connected with two sets of second positioning rods 34. The inner surfaces of the two sets of second support plates 3 are fixedly connected with two sets of second positioning sleeves 33. The second positioning rods 34 and the second positioning sleeves 33 are slidably connected. The opposite sides of the two sets of second support plates 3 are fixedly installed with second cylinders 32. The piston rod in the second cylinder 32 is fixedly connected to the top mold 31 on the same side.

[0036] Specifically, during the mold opening process, the piston rod in the first cylinder 26 retracts inward, causing the second bottom mold 25 to move downward, and the piston rod in the second cylinder 32 retracts inward, driving the top mold 31 to move to the side. Conversely, during the mold closing process, the piston rod in the first cylinder 26 pushes outward, lifting the bottom mold 25 upward, and the piston rod in the second cylinder 32 pushes outward, pushing the two sets of top molds 31 inward. At the same time, during the sliding process of the bottom mold 25, the first positioning rod 28 slides inside the first positioning sleeve 27, improving the stability of the bottom mold 25 during movement. During the sliding process of the top mold 31, the second positioning rod 34 slides inside the second positioning sleeve 33, improving the stability of the top mold 31 during sliding.

[0037] See Figure 2 , Figure 5 and Figure 6 A support rod 21 is fixedly connected to the left end of the first support plate 2. A second guide rail 23 is fixedly connected to both the support rod 21 and the surface of the first support plate 2. A second slider 41 is fixedly connected to the lower side of the fixed frame 4. A second hydraulic cylinder 24 is fixedly installed at the right end of the first support plate 2. The left end of the piston rod in the second hydraulic cylinder 24 is fixedly connected to the right end of the fixed frame 4. Two sets of side molds 42 are provided on the inner side of the fixed frame 4. Two sets of limiting grooves 45 are opened at the lower end of the two sets of side molds 42. Two sets of third positioning rods 44 are fixedly connected between the inner walls of the front and rear sides of the fixed frame 4. The third positioning rods 44 are inserted into the inside of the limiting grooves 45. A third cylinder 43 is fixedly installed on both the front and rear sides of the fixed frame 4. The piston rod in the third cylinder 43 is fixedly connected to the side mold 42 on the same side.

[0038] In addition, during the process of the second hydraulic cylinder 24 pushing the side mold 42 to the left, the second slider 41 is driven to slide inside the second guide rail 23, which improves the stability of the side mold 42 during the movement. During the opening and closing process, the side mold 42 is driven to slide by the third cylinder 43, which opens and closes the side mold 42. During the sliding process, the side mold 42 slides on the surface of the third positioning rod 44 through the limiting groove 45, which improves the stability of the side mold 42 during the movement.

[0039] The working principle of this utility model is as follows: By disassembling the mold into a bottom mold 25, two sets of side molds 42, and two sets of top molds 31, after blow molding is completed, the two sets of top molds 31 open to both sides, and the bottom mold 25 opens downwards, exposing the waste material to the outside. At this time, the fixing frame 4 and the two sets of side molds 42 are moved to the lower side of the cutting module, and the cutting module directly cuts the product waste block 51, effectively improving the production efficiency of the bottle body 5. At the same time, after the top molds 31 and the bottom mold 25 are opened, the bottle body 5 is fixed only by the two sets of side molds 42. After the cutting is completed, the fixing frame 4 and the side molds 42 are moved to the right, and the two sets of side molds 42 open to both sides. At this time, the two sets of side molds 42 only need to open a small distance to both sides, and the bottle body 5 will slide between the two sets of side molds 42. This achieves material unloading while resetting the side molds 42, thereby saving material unloading time and further improving the production efficiency of the product. The above shows and describes the basic principle, 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 of this utility model and are not intended to limit this utility model. Various changes and modifications can be made to this utility model without departing from the spirit and scope of this utility model, and all such changes and modifications fall within the scope of this utility model as claimed.
