Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy profile mold technology, specifically to an aluminum alloy profile mold that can improve molding quality. Background Technology

[0002] Molds are various molds and tools used in industrial production to obtain desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, and stamping. In short, molds are tools used to make shaped objects. These tools are composed of various parts, and different molds are composed of different parts. They mainly achieve the processing of the shape of the object by changing the physical state of the material being molded. They are widely used in blanking, die forging, cold heading, extrusion, powder metallurgy pressing, pressure casting, and compression molding or injection molding of engineering plastics, rubber, ceramics, and other products. Aluminum alloy profile molds are generally made by mold stamping.

[0003] In response, Chinese utility model patent CN217798322U discloses an aluminum alloy profile mold that can improve forming quality, relating to the field of aluminum alloy profile mold technology. The mold includes a mounting base, a lower mold mounted on the upper surface of the mounting base, a forming cavity inside the lower mold, four symmetrically arranged positioning holes on the upper surface of the lower mold, four symmetrically fixed brackets at the upper end of the mounting base, mounting plates fixed on the upper surfaces of the four brackets, a hydraulic cylinder mounted on the upper surface of the mounting plate, a connecting plate connected to the output end of the hydraulic cylinder, an upper mold mounted on the lower surface of the connecting plate, and four symmetrically arranged positioning rods at the lower end of the connecting plate. This aluminum alloy profile mold, which improves forming quality, uses the positioning holes on the lower mold. When the connecting plate moves vertically, the positioning rods can move and insert into the positioning holes, thus achieving a positioning function and effectively reducing the possibility of the upper mold shifting during workpiece stamping.

[0004] This aluminum alloy profile mold, which can improve forming quality, can play a positioning role when the connecting plate moves vertically during use, as the positioning rod and positioning hole cooperate to connect.

The movable block 13 is embedded with a threaded sleeve 131. There are four threaded sleeves 131. Two of the threaded sleeves 131 are respectively engaged with the forward lead screw 11, and the other two threaded sleeves 131 are respectively engaged with the reverse lead screw 12. Positioning rods 14 are fixedly connected to both ends of one side of the movable block 13. Mounting plates 15 are fixedly installed on both ends of one side of the upper mold 17 and the lower mold 18. Mounting plates 15 are engaged with mounting grooves 21. Positioning slots 151 are opened on both ends of one side of the mounting plates 15. Positioning rods 14 are slidably connected to positioning slots 151. When installing the upper mold 17 or the lower mold 18, the mounting plate 15 on the upper mold 17 or the lower mold 18 is inserted into the mounting groove 21 on the connecting plate 5 or the base 1. The starting motor 6 drives the connecting rod 61 and the driving bevel gear 7 to rotate, which in turn drives the driven bevel gear 8, the crossbar 9, the forward lead screw 11, and the reverse lead screw 12 to rotate. This causes the moving blocks 13 at both ends to move towards each other, so that the positioning rod 14 on one side of the moving block 13 slides into the positioning groove hole 151 on the mounting plate 15 and is simultaneously inserted into the positioning groove 23. This limits and fixes the mounting plate 15, thereby fixing and installing the upper mold 17 or the lower mold 18.

The guide holes 24 are slidably connected to the fixing rod 2, which can further guide and limit the movement of the connecting plate 5 when it moves vertically, and can further effectively reduce the possibility of the upper mold 17 shifting during movement.

[0030] Example 3:

[0031] Please see Figure 1 -4 is the third embodiment of this utility model. This embodiment is based on the above two embodiments. In actual use, the device is placed in a suitable position. The workpiece to be processed is placed on the upper surface of the lower mold 18 through the forming cavity provided on the lower mold 18. The cylinder 4 is connected to an external power source. By starting the cylinder 4, the connecting plate 5, the upper mold 17, etc., are driven to move vertically, thereby driving the upper mold 17 to move downwards towards the workpiece. At the same time, the positioning rod 16 provided on the connecting plate 5 can be inserted into the positioning hole 19, thereby playing a positioning role. This can effectively reduce the displacement of the upper mold 17 when stamping the workpiece, and can effectively improve the forming quality. By continuously driving the upper mold 17 to move, With the cooperation of the forming cavity, the upper mold 17 can stamp and form the workpiece, thereby completing the processing of the workpiece. When it is necessary to disassemble the upper mold 17 or the lower mold 18, the motor 6 is connected to an external power source. By starting the motor 6, the connecting rod 61 and the driving bevel gear 7 are rotated, which in turn drives the driven bevel gear 8, the crossbar 9, the forward lead screw 11, and the reverse lead screw 12 to rotate. This can drive the moving blocks 13 at both ends to move closer to each other, so that the positioning latch 14 moves and disengages from the positioning latch 23 and the positioning slot 151, thereby releasing the limit on the mounting plate 15. The upper mold 17 or the lower mold 18 can then be disassembled, making it convenient to disassemble and replace the upper mold 17 and the lower mold 18, which is convenient for processing different types of workpieces.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
