Abstract
Description
Technical Field
[0001] This application relates to the field of molding dies, and in particular to a chain guide plate molding die. Background Technology
[0002] In engine timing systems, the fixed guide plate serves to support and guide the timing chain's trajectory, requiring sufficient strength, low friction, good wear resistance, and self-lubrication. To meet overall engine design requirements, the fixed guide plate typically needs a dipstick hole (e.g., a path with a cross-sectional dimension of approximately 5mm × 5mm) through which the dipstick passes. Traditional dipstick hole forming methods mainly have the following problems: Hollow overall design: If the dipstick hole is designed as a hollow structure, although a continuous path can be formed, it will lead to insufficient local strength of the guide plate, making it difficult to meet the installation boundary and stress requirements, and affecting the service life and reliability of the product.
[0003] Integral core pulling molding: The core pulling method is used to form the full-length path of the dipstick hole in the mold. Since the dipstick hole is relatively long (about 300mm), the core pulling structure is complex and the mold size is large. Larger tonnage injection molding equipment is required, which not only increases the mold manufacturing cost, but also leads to a high production abnormality rate and low equipment utilization. Furthermore, problems such as jamming and core breakage are prone to occur during the core pulling process, affecting production stability and efficiency.
[0004] Therefore, existing technologies lack a molding solution that can guarantee both the forming accuracy of the dipstick hole and the strength of the guide plate structure, while also simplifying the mold structure and reducing production costs. Especially when it is necessary to balance the accuracy of the dipstick insertion path, the reinforcement requirements of the mounting hole, and the compactness and reliability of the mold, existing mold structures often cannot simultaneously meet these requirements. Summary of the Invention
[0005] To address the aforementioned issues, this application provides a chain guide plate forming mold that simplifies the mold structure, reduces manufacturing and production costs, and improves production stability and efficiency while ensuring product functionality and structural strength.
[0006] This application provides a chain guide plate forming mold with the following technical solution: A chain guide plate forming mold includes an upper mold base and a lower mold base. The lower mold base has a left mold base and a right mold base. The right mold base includes a right fixed module and a right movable mold that can slide relative to the left mold base. The upper mold base, lower mold base, left mold base, right movable mold, and right fixed module form a guide plate cavity. The side of the right movable mold facing the left mold base has a right mold insert. The right mold insert is used to insert into the guide plate cavity to form the front section of the dipstick hole. The lower mold base has a bottom protrusion. The bottom protrusion is located between the right fixed module and the left mold base. The bottom protrusion is located in the guide plate cavity to form the rear section of the dipstick hole. The front section and the rear section of the dipstick hole are connected to form a dipstick hole for the dipstick to pass through.
[0007] By adopting the above technical solution, the through-hole oil dipstick, which requires a complex long core-pulling structure for one-time molding in the existing technology, is decomposed into two sections: the front section of the oil dipstick is formed by insertion from the side of the right mold insert block, and the rear section is formed by opening from the front of the bottom protrusion. This design fundamentally avoids the use of an ultra-long core-pulling structure, greatly simplifying the mold structure and reducing the overall size. This allows for production on conventional injection molding machines, reducing equipment requirements and manufacturing costs. Simultaneously, the side insertion of the front section provides initial guidance for the oil dipstick, while the front opening of the rear section ensures the final formation of the path, together fulfilling the functional requirements of the oil dipstick hole.
[0008] Optionally, the lower mold base is provided with a cylinder one, and the upper mold base is provided with a cylinder two that is aligned with the cylinder one. The cylinder one and the cylinder two are respectively inserted into the guide plate cavity and respectively perpendicularly abut against the right mold insert block for forming the mounting hole one. The mounting hole one is used to install the guide plate.
[0009] By adopting the above technical solution, the protruding cylindrical structure on the mold naturally increases the material thickness at the forming hole (i.e., thickening), significantly enhancing the local structural strength and load-bearing capacity of the guide plate in the critical area where the dipstick hole and the mounting hole intersect. Since the cylinder abuts perpendicularly to the right mold insert, the relative positional relationship between the mounting hole and the front section of the dipstick hole is guaranteed by the mold structure itself, ensuring high precision and uniform wall thickness of the formed mounting hole, which helps guarantee the local strength of the guide plate at this joint.
[0010] Optionally, the right mold insert block corresponding to the cylindrical part is divided into insert block part one, insert block part two, and insert block part three. A gap is provided between insert block part one and insert block part two, and a gap is provided between insert block part two and insert block part three. The gap is used to form the support rib for supporting mounting hole one. The support ribs at the two locations are located on both sides of mounting hole one. A vertical rod is provided in the gap. The vertical rod is used to form a connecting hole so that the dipstick holes on both sides of the gap are connected. The vertical rod is fixed on the upper mold base or the lower mold base.
[0011] By adopting the above technical solution, the right mold insert is split and a gap is set, and support ribs are naturally formed on both sides of the mounting hole, which significantly enhances the structural strength and deformation resistance around the mounting hole; by setting a vertical rod in the gap to form a connecting hole, the problem of the front section of the dipstick hole being blocked due to the setting of support ribs is solved, ensuring the continuity of the dipstick hole path.
[0012] Optionally, the guide plate cavity is provided with a cylinder three, which is used to form the mounting hole two, which is used to install the guide plate. The cylinder three is close to the right fixed module and is fixed on the upper mold base or the lower mold base.
[0013] By adopting the above technical solution, since the mounting hole and the rear section of the dipstick hole are spatially separated and do not interfere with each other, a simple fixed cylinder can be directly formed without the need for a complex split and connecting structure like the mounting hole. This simplifies the mold design in this area and reduces the processing difficulty.
[0014] Optionally, the right moving mold is provided with a guide inclined hole, and the upper mold base is provided with a guide inclined post. The guide inclined post and the guide inclined hole are inserted and matched to drive the right mold insert block to be inserted into or pulled out of the guide plate cavity.
[0015] By adopting the above technical solution, the guide inclined column of the upper mold base is connected to the guide inclined hole on the right moving mold, which realizes the automatic insertion and extraction of the right mold insert during the mold closing / opening process. This mechanical wedge drive method replaces the cylinder or gear rack mechanism commonly used in traditional complex sliders, making the mold action more reliable, the structure simpler, and the failure rate lower.
[0016] Optionally, two guide plate cavities are provided, and a material overflow channel is provided between the two guide plate cavities.
[0017] By adopting the above technical solutions, the number of products produced in a single injection molding process is increased, production efficiency is doubled, and the overflow channel can accommodate overflow, which helps to ensure full cavity filling and stable product molding quality, thus improving production efficiency and product consistency.
[0018] Optionally, the left mold base is slidably mounted on the lower mold base, the left mold base is provided with a second guide inclined hole, and the upper mold base is provided with a second guide inclined post. The second guide inclined post and the second guide inclined hole are inserted and cooperated to drive the left mold base to move closer to or away from the right mold base.
[0019] By adopting the above technical solution, the left mold base can be moved away from the product during demolding, providing more operating space for removing the molded guide plate, reducing the difficulty of removing the part, avoiding the risk of product damage due to large clamping force, and further improving the smoothness of demolding and production stability.
[0020] Optionally, the side of the right mold insert near the right fixed module is configured as a demolding slope, and the side of the bottom protrusion near the end of the right mold insert is configured as a connecting slope that can fit with the demolding slope.
[0021] By adopting the above technical solution, when the right mold insert is inserted into place, the demolding slope and the connecting slope can fit tightly together, ensuring that the front section and the rear section of the dipstick hole, which are formed by two independent modules respectively, transition smoothly and connect seamlessly at the joint, thereby ensuring the path accuracy and surface quality of the final formed overall dipstick hole.
[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. This application completely eliminates the complex long core-pulling structure required by traditional long dipstick holes through the original "segmented open" dipstick hole molding solution. This greatly simplifies the overall structure of the mold and significantly reduces its size, so that it can be directly produced on a conventional tonnage injection molding machine. This fundamentally solves the industry problem of requiring special large equipment, high manufacturing costs, and high production abnormality rate due to excessively large molds.
[0023] 2. This application addresses the complex area where the dipstick hole path intersects with the mounting hole and reinforcing ribs. Through the ingenious design of the insert block separation, gap setting, and upright combination, the mold simultaneously achieves continuous penetration of the dipstick hole, precise forming and thickening of the mounting hole wall, and reinforcement of the supporting rib structure in one injection molding. This ensures that while the product meets the core function of smooth dipstick passage, the mechanical strength of the key mounting parts is reliably guaranteed, solving the defect of insufficient strength in simple hollow design.
[0024] 3. The molds in this application widely adopt mechanical wedge drives to replace expensive hydraulic cylinders or gear racks, making the slider (right moving mold, left mold base) more reliable and with a low failure rate; the one-mold-two-cavity design directly improves production efficiency; and the design of sliding left mold base and inclined surface fit optimizes the demolding space and cavity connection accuracy, thereby ensuring the stability, efficiency and convenience of the production process while realizing new product functions.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0040] This application discloses a chain guide plate forming mold.
[0041] like Figures 1 to 4 As shown, the chain guide plate forming mold of this embodiment includes an upper mold base 1 and a lower mold base 2. The lower mold base 2 is provided with a left mold base 3 and a right mold base 4. The right mold base 4 includes a right fixed module 42 and a right movable mold 41 that can slide relative to the left mold base 3. The right fixed module 42 and the right movable mold 41 are arranged side by side and close to each other. The upper mold base 1, lower mold base 2, left mold base 3, right movable mold 41 and right fixed module 42 form a guide plate cavity 5, which is used to form the guide plate 7. The right moving mold 41 has a right mold insert 43 on its side facing the left mold base 3. The right mold insert 43 is used to insert into the guide plate cavity 5 to form the front section 61 of the dipstick hole. The lower mold base 2 has a bottom protrusion 21. The bottom protrusion 21 is located between the right fixed module 42 and the left mold base 3. The bottom protrusion 21 is located in the guide plate cavity 5 to form the rear section 62 of the dipstick hole. The front section 61 and the rear section 62 of the dipstick hole are connected to form the dipstick hole 6 for the dipstick to pass through.
[0042] In use, the upper mold base 1 and the lower mold base 2 are closed, and at the same time, the right moving mold 41 moves towards the left mold base 3. At this point, the upper mold base 1, the lower mold base 2, the right moving mold 41, the right fixed module 42, and the left mold base 3 form a guide plate cavity 5. At this time, the right mold insert 43 is inserted into the guide plate cavity 5, and then material is poured into the guide plate cavity 5. After the material is formed, the upper mold base 1 and the lower mold base 2 are opened. After that, the right moving mold 41 moves away from the left mold base 3 and the right mold insert 43 is pulled out. Finally, the formed guide plate 7 is taken out. Due to the filling of the right mold insert 43 during pouring, a cavity is formed here after forming, which is the front section 61 of the dipstick hole. The filling of the bottom protrusion 21 on the bottom surface of the guide plate cavity 5 also forms a cavity here after forming, which is the rear section 62 of the dipstick hole. The two are connected to each other and together form the dipstick hole 6. Figures 9 to 11 As shown in the diagram, in this embodiment, the dipstick hole 6 on the guide plate 7 is segmented and designed as an open structure. The front section 61 of the dipstick hole is side-open, combined with the inlet guide, to ensure that the dipstick is inserted along the preset track. At this point, the dipstick path is basically fixed. The rear section 62 of the dipstick hole adopts a front-opening method, so that the overall path meets the design requirements. That is, there is no need to use a core-pulling method to design a hollow pipe. Because the total length of the core-pulling size is about 300mm, the mold structure is complex, the size is too large, it requires a larger injection molding equipment for production, and the defect rate is high, resulting in a waste of equipment capacity. Also, there is no need to use a front-opening method for the entire path, which would prevent the front end of the dipstick from being effectively guided during insertion.
[0043] In this embodiment, multiple holes need to be provided on the end face of the guide plate 7 for installation and fixation of the guide plate 7. The holes need to be reinforced according to the position of the dipstick hole 6. When the hole is in front of the dipstick hole 6, the following design is adopted: the lower mold base 2 is provided with a cylinder 22, and the upper mold base 1 is provided with a cylinder 12 aligned with the position of the cylinder 22. The cylinder 22 and the cylinder 12 are respectively inserted into the guide plate cavity 5 and respectively abut against the right mold insert 43 to form the mounting hole 71. The mounting hole 71 is the aforementioned hole position, which is used to install the guide plate 7. Correspondingly, the right mold insert 43, corresponding to the portion of cylinder 22, is divided into insert segment 1 431, insert segment 2 432, and insert segment 3 433. A gap is provided between insert segment 1 431 and insert segment 2 432, and a gap is provided between insert segment 2 432 and insert segment 3 433. These gaps are used to form the support ribs 73. The support ribs 73 are located on both sides of the mounting hole 71, supporting the mounting hole 71 and reinforcing its strength. Due to the existence of these gaps, after each insert segment is inserted, there is a gap in the path of the front section 61 of the dipstick hole. This gap will be filled by the poured material, which will cause the path of the front section 61 of the dipstick hole to be cut off. Therefore, if... Figure 5As shown, a support rod 11 is provided within the aforementioned gap. The support rod 11 can be fixed to the upper mold base 1 or the lower mold base 2. In this embodiment, it is preferably fixed to the upper mold base 1. The support rod 11 is used to fill the aforementioned gap so that a connecting hole 74 is formed there. The connecting hole 74 is used to connect the front sections 61 of the dipstick holes on both sides of the aforementioned gap. Two mounting holes 71 are provided, spaced apart in the area where the front section of the dipstick hole 6 is located. The two are formed and reinforced in the same way.
[0044] When the hole is located at the rear section of the dipstick hole 6, it is not related to the rear section 62 of the dipstick hole, and the two are separated. Therefore, the following design is adopted: a cylindrical three 23 is provided in the guide plate cavity 5. The cylindrical three 23 is used to form the mounting hole two 72. The mounting hole two 72 is used to install the guide plate 7. The cylindrical three 23 is close to the right fixing module 42, and the cylindrical three 23 can be fixed on the upper mold base 1 or the lower mold base 2. In this embodiment, it is preferred to be fixed on the lower mold base 2. The forming of the mounting hole two 72 only requires one cylinder. Since it is not in the groove of the rear section 62 of the dipstick hole, the outer periphery of the mounting hole two 72 is solid, so there is no need to set a reinforcing rib.
[0045] In this embodiment, as Figure 2 and Figure 6 As shown, the right moving mold 41 is provided with a guide inclined hole 401, and the upper mold base 1 is provided with a guide inclined post 13. When the upper mold base 1 and the lower mold base 2 are closed, when the guide inclined post 13 is inserted into the guide inclined hole 401, the guide inclined hole 401 moves towards the left mold base 3 under the drive of the guide inclined post 13, thereby driving the right moving mold 41 to move, so that the right mold insert 43 is inserted into the guide plate cavity 5. When demolding, the upper mold base 1 leaves the lower mold base 2, and the guide inclined post 13 gradually leaves the guide inclined hole 401, driving the guide inclined hole 401 to move away from the left mold base 3, thereby driving the right moving mold 41 to move, so that the right mold insert 43 is pulled out of the guide plate cavity 5. The lower mold base 2 is provided with a guide channel 24, and the right moving mold 41 is fixed with a guide rod 402. The guide rod 402 passes through the guide channel 24. The movement of the right moving mold 41 is guided by the guide rod 402 and the guide channel 24, thereby improving the stability and accuracy of the movement.
[0046] In this embodiment, as Figure 7 As shown, to ensure smooth connection between the front section 61 and the rear section 62 of the dipstick hole, the side of the right mold insert 43 near the right fixed module 42 is configured as a demolding slope 434, and the side of the bottom protrusion 21 near one end of the right mold insert 43 is configured as a connecting slope 201 that can fit with the demolding slope 434. When the right moving mold 41 drives the right mold insert 43 to insert into the guide plate cavity 5, it comes into contact with the connecting slope 201 of the bottom protrusion 21, thus ensuring that there is no gap at the connection between the two, so that the front and rear sections of the dipstick hole 6 formed subsequently are connected.
[0047] In this embodiment, to facilitate demolding, the left mold base 3 is designed to be slidable, moving closer to or further away from the right mold base 4. For example... Figure 2 and Figure 6 As shown, specifically, the left mold base 3 slides on the lower mold base 2. The left mold base 3 is provided with a guide inclined hole 301, and the upper mold base 1 is provided with a guide inclined post 14. The guide inclined post 14 and the guide inclined hole 301 are inserted and matched to drive the left mold base 3 to move closer to or away from the right mold base 4. Its principle is the same as that of the right moving mold 41. The lower mold base 2 is provided with a guide channel 25 to guide the left mold base 3. A guide rod 302 is fixed on the left mold base 3. The guide rod 302 passes through the guide channel 25. The movement of the left mold base 3 is guided by the guide rod 302 and the guide channel 25, which improves the stability and accuracy of the movement.
[0048] In this embodiment, as Figure 8 As shown, in order to improve efficiency, two guide plate cavities 5 are provided, and two sets of left mold base 3 and right mold base 4 are provided respectively. An excess material channel 51 is provided between the two guide plate cavities 5 to accommodate the excess material after the guide plate cavity 5 is filled.
[0049] In this embodiment, to improve the mold closing accuracy of the upper mold base 1 and the lower mold base 2, a guide post 81 and a guide hole 82 are provided between them. In this embodiment, the guide post 81 is provided on the lower mold base 2, and the guide hole 82 is provided on the upper mold base 1. The positions of the two can also be interchanged.
[0050] The implementation principle of the chain guide plate forming mold in this embodiment is as follows: The upper mold base 1 and the lower mold base 2 are closed. When the upper mold base 1 approaches the lower mold base 2, the guide inclined column 13 is inserted into the guide inclined hole 401. Driven by the guide inclined column 13, it moves towards the left mold base 3. The right moving mold 41 moves towards the left mold base 3, thereby driving the right moving mold 41 to move. At the same time, the guide inclined column 2 14 is inserted into the guide inclined hole 2 301 to drive the left mold base 3 to approach the right mold base 4. Thus, the upper mold base 1, the lower mold base 2, the right moving mold 41, the right fixed module 42, and the left mold base 3 form a guide plate cavity 5. When the right moving mold 41 moves, the right mold insert 43 is simultaneously inserted into the guide plate cavity 5. Next, material is poured into the guide plate cavity 5. After the material is formed, the upper mold base 1 and the lower mold base 2 are opened. Then, the right moving mold 41 moves away from the left mold base 3 and the right mold insert 43 is pulled out. At the same time, the left mold base 3 moves away from the right moving mold 41. Finally, the formed guide plate 7 is taken out.
[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
