Abstract
Description
Technical Field
[0001] This utility model relates to the field of injection mold technology, specifically to a slanted slider structure in a slider. Background Technology
[0002] The mounting position of the automotive headlight trim panel involves movement in two directions within the slider structure area. Due to the close proximity (14.7mm), the undercut directions differ, with an undercut length of 509mm. This product is a two-color product, requiring two molding processes; demolding cannot be achieved through two independent structures.
[0003] In modern manufacturing, especially in the automotive, electronics, medical, and home appliance sectors, plastic products are rapidly developing towards more complex structures, integrated functions, and high-precision standardization. Many products, in order to achieve specific functions (such as snaps, interfaces, and reinforcing ribs), often feature complex geometric features on their surface or interior, such as undercuts, lateral grooves, and threaded holes.
[0004] In injection molding, products with "undercut" features cannot be demolded directly through the conventional mold opening direction. To solve this problem, the mold industry commonly uses side parting and core-pulling mechanisms, the most crucial component of which is the slider.
[0005] However, when faced with increasingly complex and demanding application scenarios, traditional slider structures have gradually revealed the following technical bottlenecks and defects: 1. Difficulty in precision control and poor consistency: Traditional slider locking methods are usually simple, often using one or a few screws for direct fixation. During long-term, high-pressure injection molding production, due to thermal expansion and contraction, mechanical wear, and the impact of injection pressure, the slider (especially the angled slider forming the undercut) is prone to slight displacement. This displacement directly leads to dimensional errors, burrs, or clip failure, severely impacting product yield. Moreover, once wear occurs, traditional structures often struggle to provide precise fine-tuning compensation, requiring complete replacement, which is costly.
[0006] 2. Insufficient structural rigidity and short service life: Complex lateral core-pulling actions place high demands on the guidance and support of the slider mechanism. Some simple structures lack effective guidance and wear-resistant design, causing the slider to easily wobble or vibrate during movement. This not only aggravates the wear of mold parts and shortens the overall service life of the mold, but may also leave defects such as scratches and abrasions on the product surface.
[0007] 3. Poor motion smoothness, prone to malfunction: Improperly designed slider drive and reset processes can easily generate impacts. For example, hard collisions at the mold opening end or mold closing start can cause premature fatigue damage to mold parts. Simultaneously, an unreliable reset mechanism may result in the slider failing to fully reset, causing serious safety accidents such as mold collisions during mold closing.
[0008] 4. Inconvenient maintenance and adjustment, and long downtime: When the mold wears out or requires precision adjustment, traditional slider structures often require disassembling the entire module or large components, which is complex and time-consuming. This not only increases maintenance costs but also severely impacts production efficiency due to prolonged downtime.
[0009] Existing slider structures generally suffer from poor precision and stability, weak structural rigidity, unstable movement, and difficulties in maintenance and adjustment. These problems make it difficult to meet the stringent requirements of modern high-end precision injection molded parts for high reliability, high precision, and long service life. Summary of the Invention
[0010] This invention addresses the shortcomings of existing technologies by providing a slanted slider structure, characterized by its compact structure, good operational stability, and high efficiency.

Detailed Implementation
[0032] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.
[0033] Example: Figure 1-6 As shown, a slanted slider structure in a slider includes a mold base 10, a slider 4 at the upper end of the mold base 10, a cylinder seat 14 at the rear end of the mold base 10, a cylinder 8 on the cylinder seat 14, and a push rod 7 between the cylinder 8 and the slider 4. Front stops 12, which are fixed to the mold base 10 with countersunk bolts, are provided on both sides of the front end of the slider 4. Pressure strips 11, which are fixed to the mold base 10 with bolts, are provided at both ends of the slider 4. An injection molded part 1 is provided at the front end of the slider 4, and a slanted slider 2 is provided between the injection molded part 1 and the slider 4. A pair of symmetrically distributed locking blocks 13 are provided between the slanted slider 2 and the slider 4. Pressure blocks 9 are provided between the locking blocks 13 and the slider 4 at both ends, and between the slanted slider 2 and the slider 4 at both ends. A pair of symmetrically distributed adjusting plates 5, which are fixed to the locking blocks 13 with countersunk bolts, are provided between the rear end of the locking blocks 13 and the slider 4. A T-shaped block 3 is provided between the front end of the locking block 13 and the inclined slider 2. An elastic reset member 6, which moves correspondingly to the T-shaped block 3, is provided between the adjusting plate 5 and the pressure block 9. The elastic reset member 6 includes a spring II 20. A spring guide rod 21, which is sleeved through the spring II 20, is provided on the slider 4. A spring cover plate 19 with an "L" shape structure is provided at the upper end of the spring II 20 and is fixed to the locking block 13 with a countersunk bolt. A limiting block 15 extending to the space between the adjusting plate 5 and the slider 4 is provided at the lower end of the mold base 10. A spring I 16 is provided at the lower end of the limiting block 15. A slider seat 18 is provided between the front end of the limiting block 15 and the lower end of the limiting block 15. A slider insert 17 is provided between the front end of the slider seat 18 and the lower end of the inclined slider 2. Guide blocks 22 are provided between the slider insert 17 and the inclined slider 2, and between the slider 4 and the slider seat 18.
[0034] Mold Closing Injection: Cylinder 8 pushes slider 4 forward via push rod 7. Slider 4 moves along with its components, including inclined slider 2 and locking block 13. When the front end of slider 4 contacts front stop 12, it reaches the mold closing endpoint. At this point, inclined slider 2 and the rest of the mold together form a closed cavity, ready for injection. Locking block 13, precisely adjusted by adjusting plate 5, firmly locks inclined slider 2 to resist injection pressure.
[0035] Mold Opening and Demolding: After injection molding, cylinder 8 pulls push rod 7, causing slider 4 to move backward. Slider 4 retracts, causing inclined slider 2 to be pulled out from the undercut or side recess structure of injection molded part 1, achieving lateral demolding. During this process, elastic reset component 6 may assist in the reset of inclined slider 2 or maintain its posture. When slider 4 retracts to a certain position, it will contact limit block 15. Spring I 16 under limit block 15 acts as a buffer to prevent hard impact.
[0036] In summary, the inclined slider structure in this slider features a compact design, good operational stability, and high efficiency. It enables precise molding and stable demolding of complex injection molded parts (such as those with undercuts, lateral concave-convex structures, etc.). It integrates locking, adjustment, reset, guiding, and driving functions, thereby ensuring high-quality and high-efficiency production of complex injection molded parts.
