Description

Technical Field

[0001] This utility model belongs to the field of automotive injection molds, specifically relating to a combined sliding block and angled ejector injection structure. Background Technology

[0002] For plastic molds, conventional tunnel gate types include slider core-pulling structures and angled ejector core-pulling structures (such as...). Figure 1 As shown in the image, this structure, whether using a slider or a slanted ejector for core pulling, can only move in one direction. When the product is injected from the outer hot nozzle into the product, two directions of core pulling movement are required to ensure smooth demolding. Conventional single slanted ejector or slider core pulling cannot meet the movement requirements, resulting in movement interference. In this case, product modification is necessary, but the product may not be optimized. Alternatively, using conventional single slider or slanted ejector core pulling only requires changing the injection position, which fails to meet the gate location defined by the mold flow. Furthermore, subsequent gate trimming is costly and results in a low yield rate. This is a technical challenge of conventional tunnel core pulling gates on some products. Utility Model Content

[0003] To address the aforementioned problems in the existing technology, this utility model provides a combined sliding block and inclined ejector glue injection structure. By combining the outer sliding block and the inner inclined ejector in a tunnel-like core-pulling form, the requirement for the outer hot nozzle to inject glue into the product is met.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a combined slider and angled ejector injection structure, including a slider assembly, an angled ejector assembly, a gate, and a hot nozzle injection position. The slider assembly is located on the outside of the product, and the angled ejector assembly is located on the inside of the product. The slider assembly includes a slider, and the angled ejector assembly includes an angled ejector. The slider and the angled ejector are adapted to and in contact with each other. An L-shaped gate is provided on the same side of the slider and the angled ejector. A portion of the gate on the slider is horizontal, and another portion of the gate on the angled ejector is corner-shaped. A hot nozzle injection position is provided on the outer side of one end of the gate on the slider.

[0005] Furthermore, the slider assembly also includes pressure strips, inclined guide posts, and limiting blocks. There are two pressure strips, which are in contact with the two sides of the slider respectively. The slider slides between the two pressure strips. The inclined guide posts are obliquely arranged in the slider. The limiting blocks are located behind the slider. The lower end of the inclined guide posts is inclined towards the limiting blocks.

[0006] Furthermore, the inclined ejector assembly also includes an inclined ejector slide, an inclined ejector rod, and a sliding block. The inclined ejector rod is inclined and one end is connected to the inclined ejector, while the other end is fixed to the sliding block. The sliding block is slidably disposed in the inclined ejector slide and moves within a limited distance on the inclined ejector slide. The moving direction of the sliding block is perpendicular to the plane where the gate is located.

[0007] Compared with existing technologies, the advantages of this invention are as follows: This invention features an ingenious structure, combining an outer slider and an inner inclined ejector in a tunnel-like core-pulling configuration to meet the requirement of external hot nozzles feeding material into the product. The outer slider moves in the direction of the pressure bar, while the inner inclined ejector moves in the direction of the inclined ejector slide. This combination of the outer slider and the inner inclined ejector achieves two different core-pulling directions, effectively solving the problem of interference in a single core-pulling direction. This invention eliminates the need for product modifications while also meeting the gate location design requirements of the mold flow definition. It also reduces the need for subsequent worker trimming and results in a high product yield. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 2-5This utility model provides the following technical solution: a combined sliding block and inclined top injection structure, including a sliding block assembly, an inclined top assembly, a gate 5, and a hot nozzle injection position 7. This utility model injects glue into the product 6 from the outer hot nozzle. The sliding block assembly is located on the outer side of the product 6, and the inclined top assembly is located on the inner side of the product 6. The sliding block assembly includes a sliding block 1, and the inclined top assembly includes an inclined top 2. The sliding block 1 and the inclined top 2 are adapted to each other, and one side of the sliding block 1 and the inclined top 2 are in contact. An L-shaped gate 5 is provided on the same side of the sliding block 1 and the other side of the gate 5 is on the side of the inclined top 2. Part of the gate 5 on the sliding block 1 is horizontal, and the other part of the gate 5 on the inclined top 2 is corner-shaped. A hot nozzle injection position 7 is provided on the outer side of one end of the gate 5 on the sliding block 1. The material flow enters from the outer hot nozzle injection position 7 and enters the product 6 through the outer sliding block 1 and the inner inclined top 2. This utility model can meet the requirements of product 6, and will not cause product scrapping due to gate 5 trimming. There is no need to worry about gate 5 residue in the later stage, such as the instability of manual trimming, interference with the assembly of hand parts, and no need to change the shape of product 6 defined by the customer.

[0015] When the mold is opened and ejected, the outer slider 1 moves backward and then moves out along the horizontal direction of the gate 5 on the slider 1. Then the inner inclined ejector 2 moves out in a direction perpendicular to the plane where the gate 5 is located and away from the gate 5. After ejection, the outer slider 1 and the inner inclined ejector 2 disengage from the undercut of the gate 5 respectively, and the product 6 is successfully removed.

[0016] Specifically, the slider assembly also includes pressure strips 3, inclined guide pillars 8, and limiting blocks 9. Two pressure strips 3 are provided, each contacting one of the two sides of the slider 1. The slider 1 slides between the two pressure strips 3. The inclined guide pillars 8 are obliquely positioned within the slider 1. The limiting blocks 9 are located behind the slider 1, with the lower end of the inclined guide pillars 8 inclined towards the limiting blocks 9. During mold opening and ejection, the inclined guide pillars 8 move upwards, and then the slider 1 moves in direction A between the two pressure strips 3 under the action of the inclined guide pillars 8. After moving a certain distance, the slider 1 is limited by the limiting blocks 9, and the slider 1 stops moving.

[0017] Specifically, the inclined ejector assembly also includes an inclined ejector slide 4, an inclined ejector rod 10, and a sliding block 11. The inclined ejector rod 10 is inclined and one end is connected to the inclined ejector 2, while the other end is fixed to the sliding block 11. The sliding block 11 is slidably disposed within the inclined ejector slide 4 and moves within a limited distance on the inclined ejector slide 4. The direction of movement of the sliding block 11 is perpendicular to the plane where the gate 5 is located. During mold opening and ejection, after the slider 1 stops moving, the inclined ejector 2 follows the sliding block 11 on the inclined ejector slide 4 via the inclined ejector rod 10. Both the inclined ejector 2 and the sliding block 11 move in the direction of B. After the inclined ejector 2 and the sliding block 11 have moved a certain distance, the entire mold ejection is completed, and the inclined ejector 2 and the sliding block 11 stop moving.

[0018] In this invention, the slider 1 and the inclined top 2 are combined to form a gating structure. The gate 5 can be designed in a non-appearance position of the product 6 to prevent leakage from the gate 5. This invention can also be used to avoid situations where there are feature holes in the product 6, preventing the melt line of the feature holes from hitting the appearance surface of the product 6.

[0019] This invention effectively solves the problem of motion interference in the core-pulling direction, which is a common issue with conventional single-slider 1 or inclined top 2 tunnel core-pulling methods. This structure has been applied multiple times in actual production with significant results. The gate 5 of this invention is easy for workers to trim, has low residue requirements, and the product 6 does not interfere with or leak from other parts, effectively avoiding product scrap, reducing labor costs and trimming requirements, and improving product qualification rate.

[0020] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
