Description

Technical Field

[0001] This application relates to the field of automotive parts manufacturing technology, specifically to a core limiting structure for automotive parts molds. Background Technology

[0002] Molds are forming tools used in industrial production for processes such as injection molding, blow molding, extrusion, die casting, and stamping. They achieve the processing of product shape by changing the physical state of materials and are known as the "mother of industry". They are composed of precision parts and have specific cavity structures, enabling efficient mass production of high-precision and highly consistent products. A large number of molds are used in the production and processing of parts in the automotive production process.

[0003] The die core is a component of the mold and can complete the extrusion molding of the workpiece by pressing down. However, during the downward extrusion process, the die core is prone to displacement due to factors such as external vibration interference, excessive clearance between internal parts of the mold, and uneven reaction force applied by the workpiece, which may cause safety accidents or damage to the mold. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a core limiting structure for automotive component molds. This structure has the advantages of limiting the stroke of the core and reinforcing the limiting structure, thereby improving the stability of the core extrusion process, ensuring mold forming accuracy and operational safety, and solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution: a core limiting structure for an automotive component mold, comprising a lower mold and an upper mold, wherein the upper mold is located above the lower mold, the upper mold has a core inside, the bottom surface of the upper mold has six stroke limiting plates, the six stroke limiting plates are diagonally arranged on the outer surface of the core, the bottom of the upper mold has six L-shaped backrests, the stroke limiting plates are respectively located in the L-shaped grooves of the L-shaped backrests, and the outer surfaces of the stroke limiting plates are respectively in contact with the inner walls of the L-shaped grooves of the L-shaped backrests.

[0006] To improve the stability of the mold core, the above solution involves setting six stroke limiting plates at diagonal positions on the outer surface of the mold core. This limits the stroke of the mold core, preventing deviation during the lifting and lowering process and improving the stability of the mold core during extrusion. Furthermore, by setting an L-shaped backrest at the bottom of the upper mold and placing the stroke limiting plates within the L-shaped grooves of the backrest, the stroke limiting plates are reinforced, further optimizing their effect on limiting the stroke of the mold core and improving the safety of the mold operation process, thus preventing the mold from being easily damaged.

[0007] Furthermore, the bottom of the upper mold is provided with four upper support platforms, and the top of the lower mold is provided with four lower support platforms.

[0008] With the above scheme, four upper support platforms are set at the bottom of the upper mold and four lower support platforms are set at the top of the lower mold. During the mold closing process, the upper support platforms and the lower support platforms are in contact with each other, which can provide stable support for the upper and lower molds.

[0009] Furthermore, four cylinders are fixedly connected inside the upper mold, and the four cylinders are respectively located at the four corners of the upper mold. The output ends of the cylinders are all fixedly connected to the upper surface of the mold core.

[0010] The above solution involves installing cylinders at the four corners of the upper mold, with the cylinder outputs fixedly connected to the upper surface of the mold core. By having the four cylinders work together to drive the mold core downwards for extrusion molding, the mold core can be subjected to uniform force, ensuring that the mold core moves smoothly downwards and that the mold core can successfully complete the extrusion molding process.

[0011] Furthermore, two of the stroke limiting plates are located on the front of the mold core, two of the stroke limiting plates are located on the back of the mold core, one of the stroke limiting plates is located on the left side of the mold core, and one of the stroke limiting plates is located on the right side of the mold core. The stroke limiting plates are all located near the four corners of the mold core.

[0012] With the above scheme, six stroke limit plates are located on the front, back, left and right sides of the mold core, and are set near the four corners of the mold core. This layout can limit the mold core from multiple directions, restrict the displacement of the mold core in all directions during the downward movement, ensure that the mold core always moves along the predetermined trajectory, improve the stability and accuracy of the mold core movement, and thus ensure the forming quality of the workpiece.

[0013] Furthermore, the lower mold has two positioning plates on its left side and side surface. The top of the positioning plate is fixedly connected to the upper mold by bolts, and the bottom of the positioning plate is fixedly connected to the lower mold by bolts.

[0014] Through the above solution, the positioning plate can play the role of positioning and connecting the upper and lower molds, ensuring the stability of the mold closing. At the same time, the bolt connection facilitates the installation, disassembly and maintenance of the mold, improving production efficiency.

[0015] Furthermore, the travel limit plate is fixedly connected to the upper mold by bolts.

[0016] With the above solution, the travel limit plate is fixedly connected to the upper mold by bolts. This connection method is simple and reliable, which not only ensures the stability of the travel limit plate, but also facilitates the installation and disassembly of the travel limit plate. When the travel limit plate is worn or damaged, it can be easily replaced, reducing maintenance time and costs.

[0017] Furthermore, the L-shaped backrest is integrally formed with the upper mold.

[0018] Through the above solution, the L-shaped backrest and the upper mold are integrally formed. The integral forming design gives the L-shaped backrest and the upper mold better structural strength and stability, and can withstand the large force generated during the downward movement of the mold core, avoiding loosening or falling off between the L-shaped backrest and the upper mold, thereby ensuring the reliability of the mold core limiting structure.

[0019] Furthermore, the upper mold has four insertion holes inside, and the lower mold has four insertion rods fixedly connected inside. The insertion rods are slidably inserted into the upper mold through the insertion holes.

[0020] With the above solution, the cooperation between the insert rod and the insert hole can play a guiding role during the mold closing process, guiding the upper mold to move smoothly downward and ensuring accurate mold closing between the upper and lower molds. At the same time, this structure can also limit the relative movement of the upper and lower molds in the horizontal direction, further improving the mold closing accuracy and ensuring the forming quality of the workpiece.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects: The mold core limiting structure of this automotive part mold, by setting six stroke limiting plates at diagonal positions on the outer surface of the mold core, can limit the stroke of the mold core, prevent deviation during the lifting and lowering process of the mold core, and improve the stability of the mold core during the extrusion process. By setting an L-shaped backrest at the bottom of the upper mold and placing the stroke limiting plates in the L-shaped grooves of the L-shaped backrest, the stroke limiting plates can be reinforced, further optimizing the stroke limiting effect of the stroke limiting plates on the mold core, improving the safety of the mold operation process, and preventing the mold from being easily damaged.

The six stroke limiting plates 4 are diagonally arranged on the outer surface of the mold core 3. The bottom of the upper mold 2 is provided with six L-shaped backrests 5. The stroke limiting plates 4 are respectively located in the L-shaped grooves of the L-shaped backrests 5. The outer surface of the stroke limiting plates 4 is in contact with the inner wall of the L-shaped groove of the L-shaped backrests 5.

[0027] Please see Figure 2 , Figure 3 and Figure 5 The upper mold 2 has four upper support platforms 6 at its bottom and four lower support platforms 9 at its top. During the mold closing process, the upper support platforms 6 and the lower support platforms 9 are in contact with each other, which can provide stable support for the upper and lower molds.

[0028] Please see Figure 1 , Figure 5 and Figure 6 Four cylinders 7 are fixedly connected inside the upper mold 2. The four cylinders 7 are respectively set at the four corners of the upper mold 2. The output end of each cylinder 7 is fixedly connected to the upper surface of the mold core 3. By setting cylinders 7 at the four corners inside the upper mold 2 and fixing the output end of each cylinder 7 to the upper surface of the mold core 3, the mold core 3 is driven to move downward through the four cylinders 7 to perform extrusion molding. This can make the mold core 3 be subjected to uniform force, ensure that the mold core 3 moves downward smoothly, and ensure that the mold core 3 can successfully complete the extrusion molding action.

[0029] Please see Figure 4 , Figure 5 and Figure 6 Two stroke limit plates 4 are located on the front of the mold core 3, two stroke limit plates 4 are located on the back of the mold core 3, one stroke limit plate 4 is located on the left side of the mold core 3, and one stroke limit plate 4 is located on the right side of the mold core 3. The stroke limit plates 4 are all set near the four corners of the mold core 3. The six stroke limit plates 4 are located on the front, back, left and right sides of the mold core 3, and are set near the four corners of the mold core 3.

The top of the positioning plate 8 is fixedly connected to the upper mold 2 by bolts, and the bottom of the positioning plate 8 is fixedly connected to the lower mold 1 by bolts. The positioning plate 8 can position and connect the upper and lower molds to ensure the stability of the mold closing.

When the travel limit plate 4 is worn or damaged, it can be easily replaced, reducing maintenance time and costs.

[0032] Please see Figure 5 and Figure 7 The L-shaped backrest 5 and the upper mold 2 are integrally formed. The integral forming design gives the L-shaped backrest 5 and the upper mold 2 better structural strength and stability, and can withstand the large force generated during the downward movement of the mold core 3, avoiding loosening or falling off between the L-shaped backrest 5 and the upper mold 2, thereby ensuring the reliability of the mold core 3 limiting structure.

[0033] Please see Figure 2 , Figure 3 and Figure 5The upper mold 2 has four insertion holes 10 inside, and the lower mold 1 has four insertion rods 11 fixedly connected inside. The insertion rods 11 are slidably inserted into the upper mold 2 through the insertion holes 10. During the mold closing process, the cooperation between the insertion rods 11 and the insertion holes 10 can play a guiding role, guiding the upper mold 2 to move down smoothly, ensuring that the upper and lower molds close accurately. At the same time, this structure can also limit the relative movement of the upper and lower molds in the horizontal direction, further improving the mold closing accuracy and ensuring the forming quality of the workpiece.

[0034] In this embodiment, a core limiting structure for an automotive component mold is provided. By setting six stroke limiting plates 4 at diagonal positions on the outer surface of the core 3, the stroke of the core 3 can be limited, preventing deviation during the lifting and lowering process of the core 3 and improving the stability of the core 3 during the extrusion process. By setting an L-shaped backrest 5 at the bottom of the upper mold 2 and placing the stroke limiting plates 4 in the L-shaped grooves of the backrest 5, the stroke limiting plates 4 can be reinforced, further optimizing the stroke limiting effect of the stroke limiting plates 4 on the core 3, improving the safety of the mold operation process, and preventing the mold from being easily damaged.

[0035] It should be noted that the upper mold 2 has an internal slot to accommodate the mold core 3.

[0036] The working principle of the above embodiments is as follows: Six stroke limiting plates 4 are diagonally arranged on the outer surface of the mold core 3, and are located near the four corners of the front, back, left and right sides of the mold core 3. This all-round layout can limit the mold core 3 from multiple directions, effectively restricting the deviation of the mold core 3 during the downward movement, ensuring that the mold core 3 always moves along the predetermined trajectory, improving the stability and accuracy of the movement of the mold core 3, and thus ensuring the forming quality of the workpiece. The L-shaped backrest 5 is integrally formed with the upper mold 2, which has better structural strength and stability.
