Description

Technical Field

[0001] This application relates to the technical field of molds, and in particular to a positioning device for molds. 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 objects by changing the physical state of the material being molded, and are often referred to as the "mother of industry".

[0003] Most existing mold positioning devices are cumbersome and difficult to use, and are prone to misalignment or positioning deviation during use, making it difficult for injection molds to be properly aligned.

[0004] Therefore, in order to solve the above problems, this application provides a positioning device for molds. Utility Model Content

[0005] To address the problem of misalignment or offset being easily detected during mold positioning, this application provides a positioning device for molds.

[0006] This application provides a positioning device for a mold, including a support frame, a positioning platform fixedly installed on the top of the support frame, an air suction groove extending through the center of the inner cavity of the positioning platform, multiple through holes extending through the top of the positioning platform near the air suction groove, a fixing plate provided in the middle of the support frame, an air pump provided on the top of the fixing plate, air suction pipes connected to all four sides of the air pump, and air outlet pipes connected to all four sides of the bottom of the air suction groove, the multiple air suction pipes and air suction pipes are connected to each other by pipe joints, and L-shaped plates are provided on both sides of the top of the positioning platform, with the two L-shaped plates being diagonally distributed.

[0007] Preferably, two support plates are fixedly installed on the top of the positioning platform, and electric push rods are fixedly installed on the side of the two support plates away from the positioning platform. The output ends of the two electric push rods pass through the support plates and are fixedly connected to the L-shaped plate.

[0008] Preferably, anti-slip pads are fixedly installed on the side of both L-shaped plates near the positioning platform.

[0009] Preferably, the support frame has limit grooves on both sides of the middle section, and the fixing plate has limit blocks fixedly installed on both sides. The limit blocks slide with the limit grooves, and a handle is fixedly installed on one side of the fixing plate.

[0010] Preferably, each of the two limiting blocks has an elastic locking block fixedly installed on the side near the support frame, and each of the two limiting grooves has a through groove on the side near the elastic locking block, wherein the elastic locking block is adapted to the groove.

[0011] In summary, this application includes the following beneficial technical effects: by setting two diagonally distributed L-shaped plates, the two diagonals of the mold can be accurately fixed and positioned, which can effectively avoid the mold's offset and misalignment on the positioning table, making the mold positioning more stable, while reducing the movement and deformation of the mold during processing, thereby improving processing accuracy. By setting through holes and an air pump, the suction force generated by the air pump allows the mold to be stably adsorbed on the positioning table, making it less likely to move or fall off.

[0017] The following is in conjunction with the appendix Figure 1 - Figure 4 This application will be described in further detail.

[0018] Example:

[0019] A positioning device for a mold, as shown in the reference. Figure 1 - Figure 4The system includes a support frame 1, a positioning platform 2 fixedly mounted on the top of the support frame 1, an air intake groove through the center of the inner cavity of the positioning platform 2, and multiple through holes 7 through the top of the positioning platform 2 near the air intake groove. A fixing plate 10 is provided in the middle of the support frame 1, and an air pump 12 is provided on the top of the fixing plate 10. Air intake pipes 13 are connected to all four sides of the air pump 12, and air outlet pipes 2 are connected to all four sides of the bottom of the air intake groove. Multiple air intake pipes 13 and air outlet pipes 2 14 are connected to each other by pipe connectors 15. The top of the positioning platform 2 has two... Each part is equipped with an L-shaped plate 5, with the two L-shaped plates 5 arranged diagonally. By setting two diagonally distributed L-shaped plates 5, the two opposite corners of the mold can be accurately fixed and positioned, which can effectively prevent the mold from shifting or misaligning on the positioning table 2, making the positioning of the mold more stable. At the same time, it reduces the movement and deformation of the mold during processing, thereby improving the processing accuracy. By setting through holes 7 and air pump 12, the suction force generated by air pump 12 can make the mold stably adsorbed on the positioning table 2, making it less likely to move or fall off.

[0020] Reference Figure 1 - Figure 3 Two support plates 3 are fixedly installed on the top of the positioning platform 2. Electric push rods 4 are fixedly installed on the side of the two support plates 3 away from the positioning platform 2. The output ends of the two electric push rods 4 pass through the support plates 3 and are fixedly connected to the L-shaped plate 5. The two electric push rods 4 are electrically connected to an external power supply through an external controller. The electric push rods 4 are mainly composed of the following structural parts: motor, reducer, screw, push rod, and housing: to protect the internal components and prevent external environmental influence. When in use, the motor receives a control signal and starts to rotate. The rotation of the motor is converted into a lower speed rotational motion through the reducer. The rotational motion of the reducer is transmitted to the screw. The rotation of the screw drives the push rod. The rotation of the screw pushes the push rod to move along the axial direction to achieve linear motion. This allows the two electric push rods 4 to simultaneously push the L-shaped plate 5 closer to the mold for further positioning and alignment.

[0021] Reference Figure 1 and Figure 3 Two L-shaped plates 5 are fixedly installed with anti-slip pads 6 on the side near the positioning table 2. Both anti-slip pads 6 are made of rubber, which can prevent the L-shaped plates 5 from scratching the mold surface and increase friction, making the L-shaped plates 5 more stable.

[0022] Reference Figure 2 - Figure 4 Limiting grooves 8 are provided on both sides of the middle part of the support frame 1, and limiting blocks 9 are fixedly installed on both sides of the fixing plate 10. The limiting blocks 9 slide with the limiting grooves 8. A handle 11 is fixedly installed on one side of the fixing plate 10, which can pull out the fixing plate 10 and the air pump 12, so as to maintain or replace the air pump 12.

[0023] Reference Figure 4 Two limit blocks 9 are fixedly installed with elastic blocks 16 on the side near the support frame 1. Two limit grooves 8 are provided with slots 17 on the side near the elastic blocks 16. The elastic blocks 16 and slots 17 are adapted to fix the fixing plate 10.

[0024] Working Principle: In use, the cleaned mold is placed on top of the positioning platform 2. Then, the controller synchronously activates two electric push rods 4, which push two L-shaped plates 5 to move closer to the two opposite corners of the mold, aligning the mold on the positioning platform 2. Next, the air pump 12 is activated. The air pump 12 draws air through suction pipe 13 and suction pipe 14, causing the mold to adhere to the surface of the positioning platform 2 without displacement. Positioning is very simple. When the air pump 12 needs replacement or maintenance, it can be easily replaced through the pipes. Connector 15 disconnects the connection between suction tube 13 and suction tube 2 14. Then, pull handle 11. Handle 11 moves the fixing plate 10. The movement of the fixing plate 10 causes the elastic locking block 16 to be pulled out from the slot 17. Then, the limiting block 9 moves in the limiting groove 8, thereby pulling out the air pump 12 on the fixing plate 10. After replacement or maintenance, handle 11 can be used to push the fixing plate 10 and the limiting plate into the limiting groove 8 until they are pushed to the top. The elastic locking block 16 is locked into the slot 17 to fix the fixing plate 10. At the same time, the replacement or maintenance of the air pump 12 is completed.
