Description

Technical Field

[0001] This utility model relates to an injection molding machine for building block toys, and more particularly to an injection molding machine for building block toys, belonging to the field of injection molding machine technology. Background Technology

[0002] Injection molding machines, also known as injection molding machines or injection machines, are the main molding equipment for making various shapes of plastic products from thermoplastic or thermosetting plastics using plastic molds. They are divided into vertical, horizontal, and all-electric types. Injection molding machines can heat plastics and apply high pressure to molten plastics, causing them to be injected and fill the mold cavity.

[0003] Currently, the mold plates of injection molding machines for building block toys on the market are mainly connected to the load-bearing plate by bolts. This makes it easy to replace the mold plates. However, if the workers remove the bolts to replace the upper mold plate, the mold plate may fall quickly due to its own weight when the bolts separate from the mold plate, which may cause injury to unprepared workers.

[0004] Therefore, there is an urgent need to improve a building block toy molding injection machine to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a building block toy molding injection machine. When the operator rotates the limiting plate to make the through groove and the limiting rod slide together, the mold plate will separate from the load-bearing plate, thus preventing the mold plate from falling quickly and causing injury to unprepared operators.

[0006] To achieve the above objectives, the main technical solution adopted by this utility model includes: a building block toy molding injection molding machine, comprising two load-bearing plates, a mold plate provided on one side of each of the two load-bearing plates, a mold groove provided on one side of each mold plate, and at least two connecting structures provided between each mold plate and the two load-bearing plates;

[0007] The connection structure includes: a connecting column fixedly disposed on the two load-bearing plates, a connecting rod slidably disposed inside the connecting column, and a limiting plate located below the connecting column. The connecting column extends to the outside of the mold plate, and a connecting rod is threadedly connected to the upper end of the connecting rod. A throttle handle is fixedly installed on the upper end of one of the connecting rods.

[0008] Preferably, a limiting rod is fixedly installed at the end of the connecting rod away from the throttle, and the limiting plate is provided with a through groove and a limiting groove to allow the limiting rod to slide.

[0009] Preferably, the bottom surface of the connecting column is provided with a placement groove, and a crossbar is fixedly installed on the connecting rod. The crossbar is located above the limiting rod, and the crossbar is slidably connected to the placement groove.

[0010] The distance between the limiting rod and the crossbar allows the limiting plate to slide.

[0011] Preferably, a first turntable and a second turntable are fixedly installed on each pair of connecting rods, and the first turntable is connected to the second turntable by a belt drive.

[0012] Preferably, one of the load-bearing plates is fixedly connected to a top plate via a bracket, and an electric push rod is fixedly installed on the lower surface of the top plate;

[0013] The end of the electric push rod away from the top plate is fixedly connected to the upper surface of another load-bearing plate.

[0014] Preferably, a feed tank is fixedly installed on the upper surface of the top plate, and a high-temperature pipe is fixedly installed on the lower surface of the feed tank, with the high-temperature pipe communicating with the feed tank.

[0015] Preferably, one of the load-bearing plates and the mold plate are provided with holes for the high-temperature tube to slide through, the high-temperature tube passes through one of the load-bearing plates and communicates with one of the mold grooves.

[0016] This utility model has at least the following beneficial effects:

[0017] 1. When it is necessary to replace the mold plate, the operator turns the handle, causing the connecting rod and the connecting rod that is threadedly connected to it to slide vertically within the connecting column. This causes the limiting rod to slide out of the limiting groove. At this time, the operator turns the limiting plate so that the through groove is located at the limiting rod, thereby separating the limiting plate from the mold plate. This allows the mold plate to slide apart from the connecting column, enabling the operator to replace the mold plate. The mold plate will not fall when the operator does not turn the limiting plate. Only when the operator turns the limiting plate to make the through groove slide with the limiting rod will the mold plate separate from the load-bearing plate, preventing the mold plate from falling directly and causing injury to the operator.

[0018] 2. When the electric push rod drives one of the load-bearing plates to move downwards, the high-temperature tube passes through the holes in the load-bearing plate and the mold plate, so that the outlet of the high-temperature tube is located at the upper end of the mold groove. When the two mold plates come into contact and fit together, the operator opens the feeding switch, so that the material in the feeding tank enters the mold groove through the high-temperature tube, so that the material fills the mold groove and forms a complete building block toy.

[0025] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0026] Examples, such as Figures 1-4 As shown, a building block toy molding injection molding machine includes two load-bearing plates 1. A mold plate 7 is provided on one side of each load-bearing plate 1. A mold groove 8 is opened on one side of the mold plate 7. At least two connecting structures are provided between the mold plate 7 and the two load-bearing plates 1. By setting the mold plate 7 and opening the mold groove 8 on the mold plate 7, and the mold groove 8 having the same shape as the building block toy, when the two mold plates 7 come into contact, the two mold grooves 8 form a complete building block toy shape. By providing connecting structures between the mold plate 7 and the load-bearing plates 1, and the two connecting structures being located on both sides of the two mold plates 7 respectively, the contact of the two mold grooves 8 is not affected.

[0027] The connecting structure includes: a connecting column 12 fixedly mounted on two load-bearing plates 1, a connecting rod 14 slidably mounted inside the connecting column 12, and a limiting plate 9 located below the connecting column 12. The connecting column 12 extends to the outside of the mold plate 7. A connecting rod 15 is threadedly connected to the upper end of the connecting rod 14. A handle 151 is fixedly mounted on the upper end of one of the connecting rods 15. The connecting rod 14 extends to the outside of the limiting plate 9. The limiting plate 9 has a through groove 11 and a limiting groove 10. A limiting rod 16 is fixedly mounted on the end of the connecting rod 14 away from the handle 151. The limiting rod 16 is slidably connected to the limiting groove 10. By setting the connecting column 12 and slidably connecting the mold plate 7 to the connecting column 12, when the mold plate 7 needs to be replaced, the operator can easily... Rotating the handle 151 causes the connecting rod 15 and the connecting rod 14 threadedly connected to it to slide vertically within the connecting column 12, thereby causing the limiting rod 16 to slide out of the limiting groove 10. At this time, the operator rotates the limiting plate 9 so that the through groove 11 is located at the limiting rod 16, thereby disengaging the limiting plate 9 from the mold plate 7, and allowing the mold plate 7 to slide away from the connecting column 12. Then, the operator can replace the mold plate 7. When the operator does not rotate the limiting plate 9, the mold plate 7 will not fall. Only when the operator rotates the limiting plate 9 so that the through groove 11 slides with the limiting rod 16 will the mold plate 7 separate from the load-bearing plate 1, preventing the mold plate 7 from falling directly and causing injury to the operator.

[0028] When the mold plate 7 needs to be installed, the worker slides the through groove 11 on the limiting plate 9 and the limiting rod 16, then rotates the limiting plate 9 so that the limiting groove 10 and the limiting rod 16 are in the same direction, rotates the handle 151 so that the connecting rod 14 moves vertically in the direction of the handle 151, thereby making the limiting rod 16 slide and connect with the limiting groove 10. Then the limiting rod 16 is located in the limiting groove 10, so that the position of the limiting plate 9 is limited, thereby fixing the mold plate 7, wherein the mold plate 7 is placed between the limiting plate 9 and the load-bearing plate 1.

[0029] like Figures 1-4As shown, the bottom surface of the connecting column 12 is provided with a placement groove 13, and a crossbar 17 is fixedly installed on the connecting rod 14. The crossbar 17 is located above the limiting rod 16 and is slidably connected to the placement groove 13. A first turntable 18 and a second turntable 20 are fixedly installed on the two connecting rods 15 respectively. The first turntable 18 is connected to the second turntable 20 by a belt drive via a belt 19. By setting the crossbar 17 to be slidably connected to the placement groove 13, when the connecting rod 14 slides, the crossbar 17 slides into the placement groove 13. When the limit rod 16 is located in the limit groove 10, the first turntable 18 and the second turntable 20 are fixed on the two handles 151 respectively. The first turntable 18 is connected to the second turntable 20 by belt drive through the belt 19. When the operator turns the handle 151, the first turntable 18 is driven to rotate, which in turn drives the second turntable 20 to rotate through the belt 19. This allows the two connecting rods 14 to move vertically at the same time, which makes it convenient for the operator to operate the two limit plates 9 at the same time and saves working time.

[0030] The first turntable 18 is fixedly installed on the connecting rod 15, which is fixedly connected to the throttle handle 151.

[0031] like Figure 1 As shown, further, one of the load-bearing plates 1 is fixedly connected to the top plate 3 by a bracket. An electric push rod 4 is fixedly installed on the lower surface of the top plate 3. The end of the electric push rod 4 away from the top plate 3 is fixedly connected to the upper surface of one of the load-bearing plates 1. By fixing the electric push rod 4 between one of the load-bearing plates 1 and the top plate 3, when the worker turns on the electric push rod 4 to extend it, it drives the load-bearing plate 1 connected to it to move downward, thereby causing the two mold plates 7 to come into contact and fit together, so that the two mold slots 8 can form a complete building block toy shape.

[0032] like Figure 1 as well as Figure 2 As shown, further, a feeding tank 5 is fixedly installed on the upper surface of the top plate 3, and a high-temperature pipe 6 is fixedly installed on the lower surface of the feeding tank 5. The high-temperature pipe 6 is connected to the feeding tank 5. A hole 601 for the high-temperature pipe 6 to slide is opened on one of the load-bearing plates 1 and the mold plate 7. The high-temperature pipe 6 passes through one of the load-bearing plates 1 and is connected to one of the mold grooves 8. When the electric push rod 4 drives one of the load-bearing plates 1 to move downward, the high-temperature pipe 6 passes through the hole 601 on the load-bearing plate 1 and the mold plate 7, so that the outlet of the high-temperature pipe 6 is located at the upper end of the mold groove 8. Thus, when the two mold plates 7 come into contact and fit together, the operator opens the feeding switch, so that the material in the feeding tank 5 enters the mold groove 8 through the high-temperature pipe 6, so that the material fills the mold groove 8 to form a complete building block toy. The control of the material in the feeding tank 5 flowing into the high-temperature pipe 6 is existing technology and will not be described in detail here.

[0033] In this embodiment, as Figures 1-4 As shown in this embodiment, the principle of a building block toy molding injection molding machine is as follows:

[0034] When mold plate 7 needs to be replaced, the operator rotates handle 151, causing connecting rod 15 and its threadedly connected connecting rod 14 to slide vertically within connecting post 12. This allows limiting rod 16 to slide out of limiting groove 10. At this point, the operator rotates limiting plate 9, causing through groove 11 to be positioned at limiting rod 16, thus detaching limiting plate 9 from mold plate 7. This allows mold plate 7 to slide away from connecting post 12, enabling the operator to replace mold plate 7 to meet the needs of making different building block toys. When mold plate 7 needs to be installed, the operator slides through groove 11 on limiting plate 9 against limiting rod 16, then rotates limiting plate 9 so that limiting groove 10 and limiting rod 16 are in the same direction. The operator then rotates handle 151 to... The connecting rod 14 moves vertically in the direction of the throttle 151, thereby causing the limiting rod 16 to slide and connect with the limiting groove 10. Then, the limiting rod 16 is located in the limiting groove 10, which limits the position of the limiting plate 9 and fixes the mold plate 7. The mold plate 7 is located between the limiting plate 9 and the load-bearing plate 1. When the electric push rod 4 drives one of the load-bearing plates 1 to move downward, the high-temperature pipe 6 passes through the hole 601 on the load-bearing plate 1 and the mold plate 7, so that the outlet of the high-temperature pipe 6 is located at the upper end of the mold groove 8. When the two mold plates 7 come into contact and fit together, the operator opens the feeding switch, so that the material in the feeding tank 5 enters the mold groove 8 through the high-temperature pipe 6, so that the material fills the mold groove 8 to form a complete building block toy.
