Description

Technical Field

[0001] This utility model belongs to the field of mold technology, and in particular relates to a delayed sliding structure for a mold. Background Technology

[0002] With the rise of Industry 4.0, mold design and manufacturing are developing towards greater precision and intelligence. In this context, the design of sliding structures has become particularly important, as it directly affects mold lifespan, product quality, and production efficiency. Traditional sliding structure design often focuses on achieving basic functions, but when faced with the molding of complex parts, especially those with special geometric features and high precision requirements, the limitations of traditional design become apparent.

[0003] In mold design, ensuring precise alignment between the rear mold slide and the front mold during mold closing is a challenge when they have a contact point (i.e., a mating area). In traditional designs, the rear mold slide may prematurely contact the contact point of the front mold during mold closing, leading to unnecessary inserting forces and damage to the front mold core. This risk is further increased when the contact boss does not allow for drafting or has an extremely small draft angle (less than 0.05mm). Furthermore, if the contact area is small and the boss is high, this contact is more likely to damage the mold, affecting production stability and product quality. Therefore, achieving precise control of the slide and delayed mold closing while ensuring mold strength has become a pressing issue. Thus, we propose a delayed slide structure for molds. Utility Model Content

[0004] To address the problems existing in the prior art, the purpose of this utility model is to provide a delayed sliding structure for a mold. By designing a straight surface on the shovel base, when the mold opens, the straight surface on the shovel base abuts against the straight surface on the sliding block. When the mold closes, when the guide surface of the shovel base and the sliding block seat comes into contact, the sliding block will return to its position. At this time, the sliding block insert only has one upward movement, achieving a break-through without insertion breakage, protecting the small break-through surface from being easily burned, and enhancing production stability.

[0005] This utility model is implemented as follows: a delayed sliding structure for a mold includes a mold, with two sets of guide structures provided between the front and rear templates of the mold. Each guide structure includes a shovel base, with an inclined guide post slidably connected inside the shovel base. A first wear-resistant plate is connected to the right side of the inclined guide post. A sliding seat is engaged at the lower part of the shovel base. A spring hole is provided on the right side of the sliding seat, and a spring is provided inside the spring hole. A sliding insert is connected to the sliding seat, and a break-resistant protrusion is provided on the upper right side of the sliding insert.

[0006] Optionally, the left and right sides of the front template are provided with mounting grooves for accommodating the guide structure, and limit bolts are installed inside the mounting grooves.

[0007] Optionally, the lower part of the shovel base is connected to the travel seat by a first bolt, and the travel seat has a first through hole for the travel seat to pass through.

[0008] Optionally, the upper part of the front template is provided with a slot for accommodating the inclined guide post, and the upper part of the slot is provided with a second wear-resistant plate.

[0009] Optionally, the second wear-resistant plate has a second through hole for the inclined guide post to pass through, and the second wear-resistant plate is connected to the front template.

[0010] Optionally, the guide structure is provided with limiting plates on the left and right sides, and the limiting plates are connected to the rear template.

[0011] Optionally, the lower right side of the first wear-resistant plate is provided with an inclined edge, and the height L of the inclined edge is set to 2-5mm.

[0012] Optionally, the upper left side of the first wear-resistant plate is provided with a locking part, and the upper right side of the shovel base is provided with a locking groove.

[0013] Optionally, it also includes a front mold, which is connected to the break-off boss via a connecting block.

[0014] Optionally, the inclination angle A of the inclined guide post is less than the inclination angle B of the shovel base, and the inclination angle A of the inclined guide post is set to 5-28 degrees.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. By setting two sets of guiding structures, including a shovel base, inclined guide pillars, and a first wear-resistant plate, and integrating a spring inside the slide seat, the delayed movement of the slide insert is achieved. This design ensures that the slide insert can move in a preset sequence and time during mold opening and closing, avoiding the instantaneous impact between the slide insert and the break-off boss during mold closing, thereby reducing mold wear and potential damage risks. Ultimately, it improves the service life of the mold and the stability of the production process.

[0017] 2. By creating mounting slots on both sides of the front mold plate and using limiting bolts to fix the guide structure, the stable installation and precise positioning of the guide structure are ensured. This design enhances the reliability of the guide structure and the rigidity of the entire mold structure, preventing the guide structure from shifting or being damaged during high-pressure injection molding, thereby improving the production accuracy of the mold and the consistency of product quality.

[0018] 3. The shovel base is connected to the sliding seat by the first bolt, and the sliding seat has a pre-drilled through hole to ensure flexible movement and accurate positioning. This design allows the sliding seat to make precise delayed movements under the action of the inclined guide column, while maintaining the compactness of the structure and the overall coordination, reducing the failure rate caused by misalignment or jamming of the sliding seat in production.

[0032] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0033] like Figures 1 to 11 As shown in the figure, this utility model provides a delayed sliding structure for a mold.

[0034] In some embodiments, the delayed sliding structure includes a mold 1, and two sets of guide structures 5 are provided between the front template 2 and the rear template 3 of the mold 1. The guide structure 5 includes a shovel base 51, and an inclined guide post 54 is slidably connected inside the shovel base 51. A first wear-resistant plate 57 is bolted to the right side of the inclined guide post 54. A sliding seat 52 is snapped into the lower part of the shovel base 51. A spring hole 55 is opened on the right side of the sliding seat 52. A spring 56 is provided inside the spring hole 55. A sliding insert 53 is bolted to the sliding seat 52. A break-resistant boss 50 is provided on the upper right side of the sliding insert 53.

[0035] In some embodiments, the front template 2 has mounting grooves 4 on both the left and right sides for accommodating the guide structure 5, and the mounting grooves 4 are fitted with limit bolts 7.

[0036] The design of the mounting slot 4 not only provides a precise installation position for the guide structure 5, but also ensures the stability and reliability of the guide structure 5 during mold operation through the fixing of the limiting bolt 7. The presence of the limiting bolt 7 not only restricts the displacement of the guide structure 5, but also provides additional support when the mold closes, preventing misalignment caused by external forces, thereby ensuring the precise positioning of the slide insert 53 when the mold closes. This design reduces the risk of mold damage caused by slide instability, improving production efficiency and product quality.

[0037] In some embodiments, the lower part of the shovel base 51 is connected to the row seat 52 by a first bolt 58, and the row seat 52 is provided with a first through hole for the row seat 52 to pass through.

[0038] This connection method not only facilitates assembly and disassembly, but also ensures a firm connection between the shovel base 51 and the slide seat 52 through the tightening of the first bolt 58. The design of the first through hole allows the slide seat 52 to move smoothly along the set path, reducing shaking and deviation during movement, thereby ensuring the accurate alignment of the slide insert 53 when the mold is closed, and enhancing the overall stability and service life of the mold.

[0039] In some embodiments, the upper part of the front template 2 is provided with a slot 8 for accommodating the inclined guide post 54, and the upper part of the slot 8 is provided with a second wear-resistant plate 9.

[0040] The design of the slot 8 provides a precise guide track for the inclined guide post 54, ensuring its smooth sliding during mold opening and closing. The second wear-resistant plate 9 further reduces the coefficient of friction between the inclined guide post 54 and the front platen 2, extending the service life of the inclined guide post 54. This design not only improves the durability of the mold but also reduces maintenance costs, ensuring the high efficiency and reliability of the mold during long-term operation.

[0041] In some embodiments, the second wear-resistant plate 9 has a second through hole for the inclined guide post 54 to pass through, and the second wear-resistant plate 9 is connected to the front template 2 by bolts.

[0042] The second through hole on the second wear-resistant plate 9 not only provides a stable guiding channel for the inclined guide post 54, but also facilitates the replacement and maintenance of the second wear-resistant plate 9 through bolt connection. The use of the wear-resistant plate reduces the wear between the inclined guide post 54 and the front template 2, maintaining the good working condition of the inclined guide post 54, thereby ensuring the smooth operation of the slide seat 52 during the mold opening and closing process, and improving the overall stability and production efficiency of the mold.

[0043] In some embodiments, the guide structure 5 is provided with limiting plates 10 on the left and right sides respectively, and the limiting plates 10 are connected to the rear template 3 by bolts.

[0044] The limiting plate 10 restricts the excessive displacement of the guide structure 5 when the mold is closed, ensuring that the slide seat 52 stops in the correct position. This design avoids the slide seat 52 from shifting during movement, ensures accurate docking of the slide insert 53 with the front mold 6, reduces mold damage caused by slide misalignment, and improves the service life of the mold and the continuity of production.

[0045] In some embodiments, the lower right side of the first wear-resistant plate 57 is provided with an inclined edge 572, and the height L of the inclined edge 572 is set to 2-5mm.

[0046] The design of the inclined edge 572 allows the slide seat 52 to delay its movement during the initial opening and closing of the mold. The slide seat 52 only begins to retract when the mold opening distance H2 exceeds the height L of the inclined edge 572. This design ensures that the slide insert 53 can reach its position before the front mold 6 when the mold closes, avoiding the insertion and breakage phenomenon between the slide insert 53 and the front mold 6. This protects the small-area holes in the mold from damage and improves the stability and service life of the mold.

[0047] In some embodiments, the upper left side of the first wear-resistant plate 57 is provided with a locking part 571, and the upper right side of the shovel base 51 is provided with a locking groove.

[0048] The fitting design of the locking part 571 and the locking groove ensures a stable connection between the first wear-resistant plate 57 and the shovel base 51. This design not only simplifies the assembly process but also ensures a tight fit between the two, reducing wear and damage caused by loosening during mold operation and improving the reliability and durability of the mold.

[0049] In some embodiments, a front mold 6 is also included, which is connected to the anti-break boss 50 via a connecting block 11.

[0050] The design of the break-through boss 50 allows the sliding insert 53 to form a small-area contact with the front mold 6 when the mold is closed, achieving break-through without penetration. The connection method via the connecting block 11 ensures a reliable connection between the break-through boss 50 and the front mold 6, while also facilitating adjustment and maintenance. This design effectively protects the small-area break-through hole of the mold, reduces damage to the mold caused by penetration during production, and improves the stability and service life of the mold.

[0051] In some embodiments, the tilt angle A of the inclined guide post 54 is less than the tilt angle B of the shovel base 51, and the tilt angle A of the inclined guide post 54 is set to 5-28 degrees.

[0052] The difference between the tilt angle A of the inclined guide post 54 and the tilt angle B of the shovel base 51 allows the slide seat 52 to move smoothly along a predetermined trajectory during mold opening and closing. This angle design ensures delayed contact between the slide insert 53 and the front mold 6, avoiding direct impact of the slide insert 53 on the front mold 6 when the mold closes, thereby protecting the small area of ​​the mold from damage and improving the stability and service life of the mold.

[0053] In the prior art, the slide insert 53, which does not have a delay, will not be in place first during the mold closing process, resulting in a break at the joint with the front mold 6, which in turn makes the joint of the front mold core prone to burn-out and breakage during production.

[0054] To solve the above-mentioned technical problems, this technical solution changes the mold closing sequence of the slide insert 53 and the front mold 6 by designing a slide delay mechanism. In the event of a small surface breakage between the slide insert 53 and the front mold 6, the slide delay structure ensures that the slide arrives in position before the front mold 6 during mold closing, avoiding breakage at the moment of closing. This protects the small breakage hole from damage and improves the stability and service life of the mold 1.

[0055] The sliding delay structure is achieved by adding a first wear-resistant plate 57 to the right side of the shovel base 51. The first wear-resistant plate 57 has an inclined edge 572 with a height of L. When the mold opens, the inclined edge 572 abuts against the straight surface on the sliding block. As long as the opening distance between the front and rear molds H2 ≤ the delay height L, the sliding block 52 will not move. When the opening distance between the front and rear molds H2 > L, the sliding block 52 retracts under the action of the inclined guide post 54.

[0056] When the mold is closed, when the guide surfaces of the shovel base 51 and the slide seat 52 are in contact and the mold closing distance H2 = L, the slide seat 52 will return to its position. At this time, the slide insert 53 will only have one upward movement, which realizes that the small support surface is not easily burned and the production stability is enhanced.

[0057] The combination of the shovel base 51 and the inclined guide post 54 is key to achieving delayed sliding. The shovel base 51, as part of the guide structure 5, is internally slidably connected to the inclined guide post 54, ensuring smooth movement of the slide seat 52 along a predetermined trajectory. The inclination angle of the inclined guide post 54 matches the guide surface of the shovel base 51, ensuring the delayed effect of the slide seat 52 during mold closing and opening, and preventing improper contact between the slide insert 53 and the breakout boss 50.

[0058] The addition of the first wear-resistant plate 57 improves the durability of the structure. The inclined guide post 54 is connected to the first wear-resistant plate 57 by bolts. The material selection and design of the wear-resistant plate ensure that the friction between the inclined guide post 54 and the shovel base 51 is minimized under long-term use, reducing wear and enhancing the stability of the structure.

[0059] The spring 56 inside the spring hole 55 is a key component for achieving delayed sliding. The elastic potential energy of the spring 56 is stored during the mold opening process and released during the mold closing process, pushing the sliding seat 52 back to its original position in advance. This ensures that the sliding insert 53 only breaks by contact and does not break by insertion, reducing wear on the mold 1 components and improving production stability.

[0060] 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.
