Description

Technical Field

[0001] The utility model mainly relates to the technical field of injection molds, in particular to a multi-hole rotary injection mold for an injection molding machine. Background Art

[0002] The multi-hole rotary injection mold for injection molding machines is a special mold design. The mold usually consists of a fixed mold and a movable mold. The fixed mold is provided with an injection port, while the movable mold includes a movable mold base and a rotatable turntable. The turntable is provided with multiple mounting slots, in which the movable mold is installed. Each mold has a cavity for forming a specific product. During the injection molding process, plastic material is injected into the mold cavity through the injection port to form the desired product. At the same time, the turntable can rotate so that different hole positions can be continuously injected, thereby improving production efficiency. In order to increase production efficiency, the current rotary injection mold adopts a more complex internal structure, including multiple mounting slots and multiple molds. In addition, many intermeshing gears are added for synchronization of rotation. At the same time, complex internal injection channels are designed for smooth injection. This will result in a high manufacturing cost, which will obviously place a greater burden on the cost of use of some manufacturers. Therefore, a new type of multi-hole rotary injection mold for injection molding machines is designed. Its purpose is to achieve function through a simple structure, thereby reducing the cost of manufacturers. Utility Model Content

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] Compared with the multi-hole rotary injection mold with more parts, mounting slots and gears, this invention performs injection molding through the injection port in the fixed mold structure, performs shaping through the docking between the outlet port in the interface and the mold base, and demoulding by driving the mold base to rotate by a motor, thereby significantly reducing the manufacturing cost of the mold.

[0021] See also Figure 1A multi-hole rotary injection mold for an injection molding machine includes a fixed mold structure 1, which includes a fixed mold top plate 11. The user needs to first install the fixed mold top plate 11 on the outer wall of the shell 21. The top of the outer wall of the fixed mold top plate 11 is installed with an injection port 12. The user then performs injection molding through the injection port 12. A card block 13 is installed at the bottom of the outer wall of the fixed mold top plate 11. During installation, the card block 13 will be inserted into the inner wall of the card slot 22. One end of the injection port 12 is connected to a docking port 14. Plastic will enter the docking port 14 through the injection port 12. The inner wall of the docking port 14 is provided with a plastic outlet 15, which is in communication with the injection port 12, and the plastic is discharged through the plastic outlet 15. The inner wall of the shell 21 is provided with a card slot 22, and the bottom of the shell 21 is provided with a bottom plate 23. The movable mold mechanism 3 includes a mold base 31, and the plastic will be molded through the gap between the docking port 14 and the mold base 31. When the molded plastic needs to be taken out, the user only needs to take out the fixed mold top plate 11. After the fixed mold top plate 11 is taken out, the mold base 31 will be exposed. At this time, the mold base 31 is in a solidified state. The motor 39 is started, and a rotating rod 32 is installed at the bottom of the mold base 31 through a coupling. A driven wheel 33 is installed at one end of the rotating rod 32 through a coupling. A driving wheel 34 is installed on one side of the driven wheel 33. A linkage rod 35 is installed on the inner wall of the driving wheel 34 through a coupling. A pulley 36 is installed at one end of the linkage rod 35 through a coupling. A belt 37 is installed on the outer wall of the pulley 36. A power wheel 38 is installed at one end of the belt 37. The inner wall of the power wheel 38 is connected to the output end of the motor 39 through a coupling. After the motor 39 is started, The power wheel 38 is driven to rotate, and the power wheel 38 drives the pulley 36 to rotate through the belt 37. When the pulley 36 rotates, it drives the linkage rod 35 to rotate. At this time, after the linkage rod 35 rotates, it drives the driving wheel 34 to rotate. When the driving wheel 34 rotates, it rotates through the driven wheel 33. The driven wheel 33 then drives the mold base 31 to rotate through the rotating rod 32. When the mold base 31 rotates, the solidified plastic on the mold base 31 will be slightly separated from the mold base 31, and then the user can take the plastic out of the mold base 31.

[0022] See also Figure 1-Figure 3The three-dimensional view of the card block 13 is rectangular, and the diameter of the card block 13 is adapted to the diameter of the card slot 22. During installation, the card block 13 needs to be aligned with the card slot 22 and inserted. The three-dimensional view of the mold base 31 is cylindrical, and the diameter of the mold base 31 is adapted to the diameter of the docking port 14. After the mold base 31 is inserted into the inner wall of the docking port 14, an injection molding space will be formed, so that the plastic is molded in the space between the docking port 14 and the mold base 31. When the mold base 31 is inserted into the docking port 14, a space is formed between the mold base 31 and the port 14, and the outlet 15 and the injection port 12 are interconnected. At this time, the plastic is discharged into the space between the mold base 31 and the port 14 through the outlet 15 for shaping. After the plastic solidifies, the plastic and the mold base 31 are temporarily loosened by rotating the mold base 31. At this time, the user can remove the plastic on the mold base 31 and demold it. The cavity formed by the mutual cooperation between the mold base 31 and the port 14 becomes a complete mold, and the utility model is easy to install. It is only necessary to remove the top plate 11 and start the motor 39 to complete the demolding. The installation only requires covering the top plate 11 on the outer wall of the shell 21.

[0023] The above description of the present invention is illustrative in combination with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
