Description

Technical Field

[0001] This application relates to the field of automotive parts mold technology, specifically to a guide pillar for automotive parts molds. Background Technology

[0002] Ball guide pillars are a key mechanical transmission component that plays an important role in mechanical equipment. They are mainly used to achieve reciprocating motion. Their unique feature is the built-in ball design, which enables them to achieve high-precision positioning and guiding functions. With significant advantages such as high precision, high rigidity, low friction, and low wear, ball guide pillars are highly favored in the industrial field, especially in molds, where they undertake precise guiding operations to ensure the stability and reliability of mold operation.

[0003] However, in some automotive component mold applications, due to the large size and heavy weight of these molds, the friction between the mold and the guide pillars increases during the mold closing process, which can easily lead to scratches and affect the service life of the mold and guide pillars. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a guide post for automotive parts molds, which has advantages such as preventing scratches on the guide post and mold, improving mold guiding accuracy and stability, and extending the service life of the mold and guide post, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution: a guide post for an automotive parts mold, comprising a lower mold and an upper mold, wherein the upper mold is located above the lower mold, four ball bearing guide posts are fixedly connected to the top of the lower mold, and four guide holes are provided at the bottom of the upper mold. A soft sleeve is fitted around the ball bearing guide post, and the inner wall of the soft sleeve contacts the balls of the ball bearing guide post. Two slits are provided at the bottom of each ball bearing guide post, and two fixing plates are provided at the bottom of each ball bearing guide post, the fixing plates being respectively inserted into the interior of the slits.

[0006] The above solution addresses the issue that scratches can easily occur between the guide pillars and the mold during the mold closing process. By installing a soft sleeve around the ball guide pillars, a buffering and isolation effect can be achieved when the mold and the ball guide pillars move relative to each other.

[0007] Furthermore, the four ball guide pillars are respectively positioned near the four corners of the lower mold, and the four guide holes are respectively positioned near the four corners of the upper mold, with the positions of the ball guide pillars and guide holes corresponding to each other.

[0008] Through the above scheme, this layout allows the upper mold to be precisely guided by the ball bearing guides at all four corners during the mold closing and opening process, ensuring the stability and accuracy of the upper mold movement, effectively avoiding problems such as mold tilting and shaking caused by uneven force, and improving the mold closing accuracy and product quality.

[0009] Furthermore, the soft sleeve is made of polytetrafluoroethylene.

[0010] Through the above solution, the soft sleeve is made of polytetrafluoroethylene (PTFE), which has an extremely low coefficient of friction and good self-lubricating properties. During the mold closing motion, the inner wall of the soft sleeve contacts the balls of the ball guide post, which can effectively reduce the friction between the ball guide post and the guide hole of the upper mold, reduce the heat and wear generated by friction, thereby avoiding the occurrence of guide post scratching, extending the service life of the ball guide post and the mold, and ensuring the motion accuracy of the mold.

[0011] Furthermore, the fixing plates are fixedly connected to the lower mold by bolts.

[0012] With the above solution, the fixing plates are fixedly connected to the lower mold by bolts. This connection method is simple, reliable, and easy to install and disassemble.

[0013] Furthermore, the cuts are symmetrically arranged based on the ball guide pillars, and the fixing plate is symmetrically arranged based on the ball guide pillars.

[0014] The above scheme, with its symmetrical design, ensures that the ball guide post is subjected to uniform force after installation, thus guaranteeing its stability and preventing tilting or shaking caused by uneven force. This improves the accuracy and stability of mold guidance and ensures the normal operation of the mold.

[0015] Furthermore, the fixing plate is made of rigid material.

[0016] With the above solution, the fixing plate is made of steel, which has high strength and hardness, and can provide reliable support and fixation for the ball guide pillars. During the long-term use of the mold, the fixing plate can withstand greater pressure and impact, ensuring that the position of the ball guide pillars remains unchanged, ensuring the accuracy and stability of mold guidance, and extending the service life of the mold.

[0017] Furthermore, the top of the lower mold is symmetrically provided with two guide platforms, and the bottom of the upper mold is symmetrically provided with two guide grooves. The guide platforms are slidably connected to the upper mold through the guide grooves.

[0018] Through the above scheme, this dual-guide structure further enhances the guiding accuracy and stability of the mold. It works in conjunction with the guiding function of the ball guide pillars and guide holes to form a more complete guiding system, which can effectively avoid problems such as mold offset and shaking during mold closing and opening, thereby improving the working efficiency of the mold and the product quality.

[0019] Furthermore, the upper surface edge of the lower mold is provided with a plurality of first support platforms, and the bottom surface of the upper mold is provided with a plurality of second support platforms corresponding to the first support platforms.

[0020] With the above solution, when the mold is closed, the first support platform and the second support platform contact each other, which can provide additional support for the mold, distribute the pressure on the mold, reduce the deformation and wear of the mold, ensure the mold closing accuracy and the dimensional accuracy of the product, and extend the service life of the mold.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] This automotive parts mold guide post, by wearing a soft sleeve on the outside of the ball guide post, can buffer and isolate the relative movement between the mold and the ball guide post. The soft sleeve, made of polytetrafluoroethylene, has an extremely low coefficient of friction and good self-lubricating properties. When the guide hole of the mold contacts and slides relative to the ball guide post, the soft sleeve first contacts the inner wall of the guide hole. Its soft and smooth surface can effectively reduce the direct friction between the two, avoiding scratching and wear of the surface material of the ball guide post or the guide hole of the mold due to high-intensity friction. At the same time, the soft sleeve can also fill the small gaps that may exist between the ball guide post and the guide hole, making the movement more stable and further reducing the additional friction and wear caused by shaking and impact, thereby avoiding the scratching phenomenon of the ball guide post and the mold. By setting slits and fixing plates, the ball guide post can be reinforced, improving the stability of the ball guide post and further improving the guiding accuracy. Attached Figure Description

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] Please see Figure 2 , Figure 3 and Figure 4 In this embodiment, an automotive parts mold guide post includes a lower mold 1 and an upper mold 2. The upper mold 2 is located above the lower mold 1. Four ball guide posts 3 are fixedly connected to the top of the lower mold 1. The bottom of the upper mold 2 is provided with four guide holes 4. A soft sleeve 5 is sleeved on the outside of the ball guide post 3. The inner wall of the soft sleeve 5 contacts the balls of the ball guide post 3. Two cuts 6 are opened at the bottom of each ball guide post 3. Two fixing plates 7 are provided at the bottom of each ball guide post 3. The fixing plates 7 are respectively inserted into the inside of the cuts 6.

[0032] Please see Figure 1 , Figure 2 and Figure 3 Four ball bearing guide pillars 3 are respectively positioned near the four corners of the lower mold 1, and four guide holes 4 are respectively positioned near the four corners of the upper mold 2. The positions of the ball bearing guide pillars 3 and the guide holes 4 correspond to each other. This layout allows the four corners of the upper mold 2 to be precisely guided by the ball bearing guide pillars 3 simultaneously during the mold closing and opening process, ensuring the stability and accuracy of the movement of the upper mold 2. It effectively avoids problems such as mold tilting and shaking caused by uneven force, and improves the mold closing accuracy and product quality.

[0033] Please see Figure 4 and Figure 5 The soft sleeve 5 is made of polytetrafluoroethylene (PTFE). PTFE has an extremely low coefficient of friction and good self-lubricating properties. During the mold closing process, the inner wall of the soft sleeve 5 contacts the balls of the ball guide post 3, effectively reducing the friction between the ball guide post 3 and the guide hole 4 of the upper mold 2. This reduces the heat and wear generated by friction, thus preventing the guide post from scratching and extending the service life of the ball guide post 3 and the mold, while also ensuring the movement accuracy of the mold.

[0034] Please see Figure 2 and Figure 4The fixing plates 7 are fixedly connected to the lower mold 1 by bolts. This connection method is simple and reliable, and is easy to install and disassemble.

[0035] Please see Figure 2 , Figure 4 and Figure 5 The cutout 6 is symmetrically arranged based on the ball guide post 3, and the fixing plate 7 is symmetrically arranged based on the ball guide post 3. The symmetrical design ensures that the ball guide post 3 is subjected to uniform force after installation, which can guarantee the stability of the ball guide post 3 and avoid tilting or shaking of the ball guide post 3 due to uneven force. This improves the accuracy and stability of mold guidance and ensures the normal operation of the mold.

[0036] Please see Figure 2 and Figure 4 The fixing plate 7 is made of steel. Steel has high strength and hardness, which can provide reliable support and fixation for the ball guide post 3. During the long-term use of the mold, the fixing plate 7 can withstand greater pressure and impact, ensuring that the position of the ball guide post 3 remains unchanged, ensuring the accuracy and stability of mold guidance, and extending the service life of the mold.

[0037] Please see Figure 1 , Figure 2 and Figure 3 The lower mold 1 has two guide platforms 8 symmetrically arranged at its top, and the upper mold 2 has two guide grooves 9 symmetrically arranged at its bottom. The guide platforms 8 are slidably connected to the upper mold 2 through the guide grooves 9. This double guide structure further enhances the guiding accuracy and stability of the mold. Together with the guiding action of the ball guide post 3 and the guide hole 4, it forms a more complete guiding system, which can effectively avoid problems such as offset and shaking of the mold during mold closing and opening, and improve the working efficiency of the mold and the product quality.

[0038] Please see Figure 2 and Figure 3 The upper surface edge of the lower mold 1 is provided with multiple first support platforms 10, and the bottom surface of the upper mold 2 is provided with multiple second support platforms 11 corresponding to the first support platforms 10. When the mold is closed, the first support platforms 10 and the second support platforms 11 contact each other, which can provide additional support for the mold, distribute the pressure on the mold, reduce the deformation and wear of the mold, ensure the mold closing accuracy and the dimensional accuracy of the product, and extend the service life of the mold.

[0039] In this embodiment, an automotive parts mold guide post is provided. By sleeved with a soft sleeve 5 on the outside of the ball guide post 3, it can buffer and isolate the relative movement between the mold and the ball guide post 3. The soft sleeve 5, made of polytetrafluoroethylene, has an extremely low coefficient of friction and good self-lubricating properties. When the guide hole 4 of the mold contacts and slides relative to the ball guide post 3, the soft sleeve 5 first contacts the inner wall of the guide hole 4. Its soft and smooth surface can effectively reduce the direct friction between the two, avoiding scratching and wear of the surface material of the ball guide post 3 or the guide hole 4 of the mold due to high-intensity friction. At the same time, the soft sleeve 5 can also fill the possible small gaps between the ball guide post 3 and the guide hole 4, making the movement more stable and further reducing the additional friction and wear caused by shaking and impact, thereby avoiding the scratching phenomenon of the ball guide post 3 and the mold. By setting the notch 6 and the fixing plate 7, the ball guide post 3 can be reinforced, improving the stability of the ball guide post 3 and further improving the guiding accuracy.

[0040] The working principle of the above embodiments is as follows:

[0041] The soft sleeve 5, which is made of polytetrafluoroethylene (PTFE), is fitted around the ball guide post 3. It has an extremely low coefficient of friction and excellent self-lubricating properties. When the mold and the ball guide post 3 move relative to each other, the soft sleeve 5 first contacts the inner wall of the guide hole 4. Its soft and smooth surface effectively reduces the direct friction between them, preventing scratches and wear on the surface material of the ball guide post 3 or the guide hole 4 due to high-intensity friction. Simultaneously, the soft sleeve 5 fills any small gaps that may exist between the ball guide post 3 and the guide hole 4, making the movement smoother and further reducing additional friction and wear caused by shaking and impact. This prevents scratching of the ball guide post 3 and the mold, extending their service life and ensuring the movement accuracy of the mold. Each ball guide post 3 has two notches 6 at its bottom, and two fixing plates 7 are correspondingly provided. The fixing plates 7 are respectively inserted into the inside of the notches 6 and are fixedly connected to the lower mold 1 by bolts. The notches 6 and fixing plates 7 are symmetrically arranged based on the ball guide post 3. This design ensures that the ball guide post 3 is subjected to uniform force after installation, which can ensure the stability of the ball guide post 3, thereby improving the accuracy and stability of mold guidance and ensuring the normal operation of the mold. The fixing plates 7 are made of rigid material with high strength and hardness, which can provide reliable support and fixation for the ball guide post 3. During the long-term use of the mold, they can withstand greater pressure and impact, ensuring that the position of the ball guide post 3 remains unchanged, and further extending the service life of the mold.
