[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figure 1-6 This utility model provides a technical solution: an injection molding structure, including an injection molding device 2 disposed on the upper end of a worktable 1 and a mold 3 disposed on the upper end of the worktable 1 and connected to the injection molding device 2, and further including:
[0026] Demolding device 4 is set on the upper end of workbench 1 and connected to mold 3, and is used to demold the formed insulation board;
[0027] Ejection device 5 is installed on demolding device 4 and is connected to mold 3, used to eject the insulation board in mold 3;
[0028] The collection box 6 is located at the lower end of the workbench 1 and below the ejector device 5, and is used to collect the insulation board.
[0029] In a specific embodiment, the injection molding device 2 includes a motor 21 fixed on the upper end of the worktable 1, a rotating shaft 22 disposed at the power output end of the motor 21, a heating box 23 disposed on the upper end of the worktable 1, a conveying pipe 231 disposed on the side of the heating box 23 away from the motor 21, a hopper 24 fixed on the upper end of the heating box 23, and an injection port 26 disposed on the side of the conveying pipe 231 away from the heating box 23 and connected to the injection port 3102. The rotating shaft 22 is fitted with a spiral blade 25 at the position inside the conveying pipe 231, and a heat preservation frame 27 is fixed on the outside of the conveying pipe 231.
[0030] It should be noted that during operation, the insulation board raw material is added into the hopper 24, and then the heating box 23 is turned on to heat the raw material. The heated raw material flows into the conveying pipe 231. The motor 21 is started, driving the rotating shaft 22 to rotate the spiral blade 25, conveying the molten raw material to the injection port 26, and then into the mold 3. After the insulation board is formed, the demolding device 4 can automatically separate the mold 3, and the ejection device 5 can quickly push the insulation board out of the mold 3 and drop it into the collection box 6 below. This process greatly reduces manual intervention, improves production efficiency, and reduces safety hazards. In addition, the ejection force of the ejection device 5 on the insulation board is evenly distributed on the insulation board, which can make the insulation board evenly distributed, reduce the damage to the insulation board during demolding, improve the production efficiency of the insulation board, and also ensure the integrity of the insulation board.
[0031] In one embodiment, the mold 3 includes a fixed mold 31 and a moving mold 32. The fixed mold 31 has a molding cavity 3101 for storing injection molding raw materials, and the side of the fixed mold 31 near the injection molding device 2 has an injection port 3102 connected to the molding cavity 3101.
[0032] With this design, the injection port 3102 is directly connected to the molding cavity 3101, which allows the injection molding material to enter the molding cavity 3101 quickly and accurately from the injection port 26, improving injection efficiency and the precision of the finished product, reducing material waste and leakage during the injection process, and ensuring the continuity and stability of the injection process.
[0033] In one embodiment, the demolding device 4 includes a fixed plate 42 fixed to the upper end of the workbench 1, a fixed frame 43 fixed to the workbench 1 for mounting the fixed mold 31, a power component 41 disposed on the fixed plate 42, and a guide rod 44 disposed on the moving mold 32. The power component 41 is connected to the moving mold 32, the moving mold 32 is sleeved on the guide rod 44, and the guide rod 44 passes through the fixed plate 42. The power component 41 includes, but is not limited to, a hydraulic cylinder, a linear guide rail, an electric push rod, and a pneumatic cylinder.
[0034] With this design, the power component 41 is connected to the moving mold 32. After the insulation board is formed, the power component 41 drives the moving mold 32 to move closer to the fixed plate 42. When the insulation board moves above the collection frame 6, the ejection device 5 is activated to eject the insulation board from the moving mold 32 and then it falls into the collection frame 6. The guide rod 44 passes through the fixed plate 42 and is fixed to the moving mold 32. This plays a guiding and positioning role. During the demolding process, the guide rod 44 can ensure that the moving mold 32 moves in the correct direction and avoids deviation or tilting, thereby ensuring the accuracy and stability of demolding. The demolding process can be completed automatically by the power component 41 without manual operation, which not only improves production efficiency but also reduces labor costs.
[0035] In one embodiment, a movable plate 46 is provided on the portion of the guide rod 44 located between the moving mold 32 and the fixed plate 42, and a control button 45 is provided on the side of the fixed plate 42 near the moving mold 32.
[0036] With this design, the movable plate 46 is fixed on the guide rod 44 and moves with the guide rod 44. When the insulation board moves to the set position, the movable plate 46 presses the control button 45, which causes the control button 45 to open the ejection device 5, which can more accurately control the demolding position of the insulation board and facilitate subsequent collection work.
[0037] In one embodiment, the ejection device 5 includes an air pump 51 disposed on the upper end of the fixed plate 42, an air distribution pipe 52 connected to the air outlet of the air pump 51, and a connecting pipe 53 disposed on the air distribution pipe 52 and connected to the moving mold 32. An air outlet 3201 is provided at the position where the moving mold 32 is connected to the air distribution pipe 52. A one-way inflation valve 3202 is provided inside the air outlet 3201. The air pump 51 is electrically connected to the control button 45 through a PLC control element.
[0038] With this design, the air pump 51 inflates the air outlet 3201 in the moving mold 32 through the air distribution pipe 52 and the connecting pipe 53, using air pressure to eject the product between the moving mold 32 and the fixed mold 31. Multiple connecting pipes 53 are evenly distributed on the moving mold 32, which ensures that the insulation board in the moving mold 32 is subjected to uniform force during demolding. The one-way inflation valve 3202 is existing technology and will not be described in detail again. The setting of the one-way inflation valve 3202 ensures that the gas can only flow in one direction, that is, only from the air pump 51 to the moving mold 32, avoiding the insulation board material from flowing into the interior of the air outlet 3201, causing blockage of the air outlet 3201, and affecting the ejection efficiency of the ejection device 5 for the insulation board. The electrical connection between the PLC control element and the control button 45 realizes the automatic control of the ejection device 5. When the moving plate 46 opens the control button 45, the PLC control element turns on the air pump 51 and then pushes out the insulation board in the moving mold 32.
[0039] In one embodiment, a cooling fan 7 is provided on the fixed frame 43 above the fixed mold 31, and a slot 101 is provided on the worktable 1 below the guide rod 44.
[0040] With this design, the cooling fan 7 can dissipate the heat generated by the fixed mold 31 and the moving mold 32 during operation in a timely manner, which can accelerate the cooling process of the insulation board, shorten the production cycle, and improve production efficiency. The empty slot 101 is set above the collection frame 6, which makes it convenient for the demolded insulation board to fall from the empty slot 101 into the interior of the collection frame 6.
