Description

Technical Field

[0001] This utility model relates to the field of mold base technology, and in particular to a lightweight automotive injection mold base. Background Technology

[0002] The mold frame is the core basic component in mold manufacturing, also known as the mold holder or mold core base. It is a metal structural frame used to install, fix and support the mold forming parts. The mold frame is a reusable structural unit composed of multiple standardized templates and guide components. In the current automotive parts manufacturing, injection molds are used to produce injection molded parts to reduce the weight of the car body.

[0003] The existing announcement number CN205767042U, entitled "A Plastic Mold Frame," includes a base plate and a panel. The four corner edges of the upper surface of the panel have cup-head screw slots. The lower end of the panel is connected to an upper core material. The upper core material is installed on the edge of the lower surface of the panel through cup-head screws inserted into the cup-head screw slots. The four corner edges of the upper core material are fixedly connected to upper support feet through angled-hole cup-head screws. The support feet have cavities for connecting guide pillars. Square iron blocks are connected to the upper end of the base plate, and these blocks are located on both sides of the base plate. This plastic mold frame allows for multiple core and cavity processing, assembly, sprue sleeve fitting, and ejector pin fitting by changing the return pin, lower core material, and upper core material. It avoids the disadvantages of slow processing time, numerous complex processes, and difficulty in guaranteeing precision in conventional plastic mold machining processes, greatly improving product quality and production efficiency.

[0004] However, the guide rods of existing mold frames are usually connected to the lower mold frame. Although this design can simplify the installation process, it makes it inconvenient to disassemble and repair the guide mechanism separately when replacing or maintaining it, due to the tight connection between the guide mechanism and the lower mold frame. This, in turn, affects the efficiency of disassembly and maintenance of the entire mold frame. Utility Model Content

In this lightweight automotive injection mold frame, the mold frame body 1 achieves efficient installation and disassembly through the design of its internal guides 11, slide plates 12, guide rods 13 and inserts 14, thereby improving the overall durability and flexibility of the mold. Specifically, the mold base body 1, as the basic frame of the entire mold base, provides stable support for the fixed mold base plate 2 and the moving mold base plate 3; the connecting frame 111 and sliding frame 115 in the guide component 11 ensure the precise sliding of the slide plate 12, improving the accuracy of the mold; the slide plate 12, through the cooperation of the insert 121 and the insert block 14, achieves precise positioning and stable connection between the slide plate 12 and the mold base body 1; the guide rods 13, through the interlocking of the slots 131 and the inserts 132 between multiple guide rods 13, not only enhance the guiding function of the slide plate 12, but also adapt to the needs of different mold sizes. The overall working principle is: through the mutual cooperation of the slide plate 12, the guide component 11 and the guide rods 13, the mold can maintain a precise relative position and movement trajectory during use, ensuring the high precision and consistency of the injection molded products. At the same time, the design of the insert block 14 and the slot 131 also facilitates the quick assembly and disassembly of the mold, improving production efficiency.

[0023] like Figure 4As shown, a rotating base 112 is vertically fixed to the top surface of the connecting frame 111, and a rotating column 113 is horizontally rotatably connected to the rotating base 112. Both ends of the rotating column 113 are horizontally fixed with screws 114. A screw seat 125 is vertically fixed to the top surface of the slide plate 12, and the screw seat 125 is threaded through the screws 114. The connecting frame 111 provides a stable mounting base, with the rotating base 112 vertically fixed and supported on its top surface. The design of the rotating base 112 allows the rotating column 113 to rotate horizontally, increasing the system's flexibility and range of applications. The rotating column 113's stability is ensured by the screws 114 fixed at both ends, and adjustment and connection functions are provided. The screw seat 125 is vertically fixed to the top surface of the slide plate 12, and the screw seat 125 is threaded through the screws 114, allowing the slide plate 12 to move and be positioned relative to the connecting frame 111 in a specified direction. In summary, the working principle of this device is as follows: the connecting frame 111 serves as the basic support, the rotating base 112 allows the rotating column 113 to rotate flexibly to adapt to different needs, and the threaded connection between the screw 114 and the screw hole seat 125 enables the precise adjustment and positioning of the slide plate 12, thereby realizing the flexible adjustment and fixing functions of the equipment.

The slot 131 can be fixedly connected to the end of the guide rod 13, while the post 132 can be inserted into the end of another guide rod 13, achieving a fixed insertion. In this way, the end blocks 14 ensure a tight fit between the guide member 11 and the guide rods 13, thus providing stable support and guidance. When multiple guide rods 13 are installed on the guide member 11, the cooperation of the slots 131 and posts 132 allows the guide rods 13 to be firmly fixed on the guide member 11, forming a stable guiding system.

[0027] The working principle of this embodiment, First, based on the actual thickness requirements and mold opening distance of the injection mold, the rotating column 113 is rotated and its stability is ensured by screws 114 fixed at both ends. A screw hole seat 125 is vertically fixed on the top surface of the slide plate 12. The screw hole seat 125 and the screw 114 are assembled by threaded connection, allowing the slide plate 12 to move and be positioned relative to the connecting frame 111 in a specified direction, adapting to the actual thickness requirements and mold opening distance of the injection mold. Then, insert block 14 is inserted into insert cylinder 121. Guide rod 13, through the interlocking of slot 131 and insert post 132 between multiple guide rods 13, not only enhances the guiding function of slide plate 12, but also adapts to the needs of different mold sizes. Then, the ends of the assembled multiple guide rods 13 are used to fix the fixed mold and moving mold in the injection mold onto fixed mold base plate 2 and moving mold base plate 3 respectively.
