Technical Field

[0001] This utility model relates to the field of mold making technology, specifically a height-adjustable modular aluminum alloy mold frame. Background Technology

[0002] The positioning and guiding of molds (injection molding, die casting, stamping) usually require the use of aluminum alloy mold frames. The aluminum alloy mold frame usually has a fixed base and a slide above the fixed base. The fixed mold and the moving mold are installed on opposite sides of the fixed base and the slide, respectively. The aluminum alloy mold frame is equipped with guide columns to guide the slide up and down. Under the guidance of the guide columns, the moving mold can slide stably and can also accurately close with the fixed mold.

[0003] Currently, there are many types of molds, and their thicknesses vary. For molds with the same shape but different thicknesses, it is usually necessary to make aluminum alloy mold frames of different specifications (different heights). This increases the difficulty and cost of production. Therefore, there is an urgent need in the market for a modular aluminum alloy mold frame that can be adjusted in height to accommodate different thicknesses.

[0004] Therefore, this utility model provides a height-adjustable modular aluminum alloy mold frame. Utility Model Content

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Please see Figures 1 to 4 This utility model provides a technical solution: a height-adjustable modular aluminum alloy mold frame, including a base 1, with a connecting hole through which the upper end face of the base 1 can be opened, and the fixed mold can be fixed above the base 1 through the connecting hole and bolts.

[0025] A guide frame 2 is provided above the base 1. A moving mold connecting plate 8 is slidably connected inside the guide frame 2. The guide frame 2 guides the sliding of the moving mold connecting plate 8 and ensures that the moving mold connecting plate 8 moves stably up and down. Mounting holes can also be opened through the surface of the moving mold connecting plate 8. The moving mold is fixedly installed below the moving mold connecting plate 8 by bolts and mounting holes.

[0026] The guide frame 2 includes a top plate 21 and four guide pillars 22 located at the bottom of the top plate 21. The guide pillars 22 are cylindrical structures. The upper end of the base 1 is fixedly connected with limiting guide pillars 3 that correspond one-to-one with the four guide pillars 22. It also includes a pad 4 located between the guide pillars 22 and the limiting guide pillars 3. The pad 4 is inserted into the guide pillars 22 and the limiting guide pillars 3. The opposite ends of the guide pillars 22 and the limiting guide pillars 3 are inserted into each other. Thus, the height of the entire guide frame 2 can be adjusted by adding or removing the pad 4, thereby making it suitable for positioning and guiding molds of two different thicknesses.

[0027] Specifically, the top of the limiting guide post 3 is fixedly connected to the connector 6, and the bottom of the guide post 22 is provided with a plug groove 7 that matches the connector 6. One side of the pad 4 is fixedly connected to the connector 6 and the other side is provided with a plug groove 7. Multiple pads 4 can be connected in a first-to-first plug-in manner. This arrangement allows the number of pads 4 to be stacked as needed, thereby increasing the range of height adjustment of this aluminum alloy mold frame and making it suitable for molds of various thicknesses.

[0028] Furthermore, after the limiting guide post 3 and the guide post 22 are inserted, they are coaxial and have the same outer diameter. After the limiting guide post 3 is connected to the guide post 22 through the pad 4, all three are coaxial and have the same outer diameter. During manufacturing, the maximum outer diameter of the plug 6 is smaller than the outer diameter of the limiting guide post 3. The plug 6, the pad 4, and the limiting guide post 3 are all coaxial. The plug groove 7 is coaxial with the pad 4 and the guide post 22. This arrangement allows the limiting guide post 3, the guide post 22, and the pad 4 to be combined into a complete and smooth optical axis structure, thereby improving the strength of the combined optical axis support.

[0029] In this embodiment, the top of the limiting guide post 3 is fixedly connected to the connector 6, the bottom of the guide post 22 is provided with a plug groove 7 that is compatible with the connector 6, and one side of the pad 4 is fixedly connected to the connector 6 and the other side is provided with a plug groove 7.

[0030] In this embodiment, the connector 6 is a truncated cone structure with the small end facing outward. The truncated cone utilizes the guiding effect of the outer cone surface to greatly reduce the difficulty of connecting the connector 6 and the insertion slot 7. This design makes it easier to connect adjacent pads 4, and the fit is tighter and more reliable after connection.

[0031] In this embodiment, the moving mold connecting plate 8 is a rectangular plate structure with guide sleeves 81 that are fixedly installed on its surface near the four corners. The guide sleeves 81 are fitted on the adjacent guide posts 22, and the moving mold connecting plate 8 can move smoothly up and down along the guide posts 22 through the guide sleeves 81.

[0032] In this embodiment, a lifting drive rod 5 is provided between the base 1 and the top plate 21. The function of the lifting drive rod 5 is to control the lifting and lowering of the entire guide frame 2 relative to the base 1, thereby facilitating the addition or removal of the pad platform 4.

[0033] Specifically, the lifting drive rod 5 includes a transmission screw 51 and a screw sleeve 52. There are two transmission screws 51, located on both sides of the guide frame 2. The bottom of the transmission screw 51 is rotatably connected to the base 1. Specifically, a positioning sleeve 11 is fixedly connected to the plate surface of the base 1 and sleeved outside the transmission screw 51. The positioning sleeve 11 is rotatably connected to the transmission screw 51. The lower end face of the top plate 21 is fixedly connected to the screw sleeve 52, which is screwed into the transmission screw 51. When the two transmission screws 51 on both sides of the guide frame 2 rotate simultaneously, they can drive the entire guide frame 2 to rise and fall through the top plate 21.

[0034] Furthermore, a screw handle 511 is fixedly connected to the bottom of the transmission screw 51. The screw handle 511 is a handheld component for controlling the rotation of the transmission screw 51.

[0035] Working principle: Before use, install a control cylinder or control oil cylinder on the top plate 21, and then fix the output end of the control cylinder or control oil cylinder to the back of the moving mold connecting plate 8, thereby realizing the control function of the moving mold connecting plate 8 moving up and down relative to the guide frame 2. When installing the mold, when the mold to be installed is large, hold the handle 511 and simultaneously control the two transmission screws 51 to rotate, the top plate 21 moves up, the guide post 22 and the limiting guide post 3 separate, and then, according to the height requirement, stack one or two pads 4 between the guide post 22 and the limiting guide post 3 through the cooperation of the plug joint 6 and the plug groove 7, and then control the transmission screw 51 to rotate in the opposite direction. At this time, the plug joint 6 at the bottom of the guide post 22 is inserted into the plug groove 7 on the pad 4 below, and then tighten the transmission screw 51 to ensure that there are no gaps between the guide post 22, the limiting guide post 3 and the pad 4. At this time, the entire guide frame 2 is in an elevated state, suitable for the current mold.

[0036] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
