Description

Technical Field

[0001] This utility model relates to the field of demolding technology for injection mold products, specifically a conversion mechanism for a large downslope slider. Background Technology

[0002] With social development and continuous improvement in mold technology, reducing raw material consumption and increasing mold automation are the development directions of injection mold technology, while ensuring product quality. Due to the structural requirements of the product, when the undercut angle exceeds 45°, conventional slider structures cannot achieve this angle of undercut. For example... Figure 1 The product shown exhibits the aforementioned problems during injection molding of this shape. See also... Figure 2 and Figure 3 ,in Figure 3 The area A shown in the image is an inverted downhill slope with an angle of 47°.

[0003] The main reasons for the aforementioned problems are as follows:

[0004] 1. Because the downward slope angle is too large, the slider cannot be locked properly. During the injection molding process, the slider will be pushed back by the injection pressure, causing flash on the product and failing to meet the product requirements.

[0005] 2. Because the downslope angle is too large, the thickness of the template will be increased accordingly, resulting in a great waste of materials.

[0006] Therefore, a conversion mechanism for a large downhill slider needs to be designed. Utility Model Content

[0007] To address one of the shortcomings of existing technologies, this utility model provides a conversion mechanism for a slider on a steep downhill slope, solving the problem of slider setting for steep downhill angles.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a conversion mechanism for a large downhill slider, comprising a moving template and a fixed template, wherein a slider mechanism is provided between the moving template and the fixed template, the moving template being able to move toward or away from the fixed template, the slider mechanism comprising:

[0009] The slider is positioned on one side corresponding to the product's undercut position.

[0010] A slider seat, linked to the slider, is slidable on the fixed template.

[0011] The linkage component is connected to the moving template and is linked to the slider seat; when the moving template moves away from the fixed template, the linkage component can drive the slider away from the undercut position of the product through the slider seat.

[0012] Preferably, the slider seat has a groove corresponding to the slider, and the slider is slidably connected to the slider seat through the groove; when the moving template moves away from the fixed template, the slider moves along the groove on the slider seat in a direction away from the product's undercut position.

[0016] The first pressure block is an inclined block. The first pressure block is fixedly connected to the fixed template and slidably connected to the slider. The upper end of the first pressure block faces the product and the lower end faces the slider seat.

[0017] The upper end of the slider corresponds to the product setting, the lower end of the slider extends to the outer side of the lower end of the first pressure block, and the lower end of the slider is slidably connected to the slider seat.

[0018] Preferably, the groove on the slider seat is a "T" shaped groove, and the slider is provided with a "T" shaped part corresponding to the groove.

[0019] Preferably, it also includes:

[0020] The second guide assembly is disposed between the slider seat and the fixed template, and the slider seat and the second guide assembly are slidably connected.

[0021] Preferably, the second guide component includes:

[0026] The shovel base is fixedly connected to the moving template, and the guide rod is fixedly installed on the shovel base.

[0027] Preferably, it also includes:

[0028] A limiting component is provided to limit the movement of the slider seat. The limiting component includes:

[0029] The first limiting member is fixedly connected to the fixed template, and the first limiting member is disposed on the slider seat in the direction of the horizontal outer side of the fixed template;

[0030] The second limiting member is located on the side of the slider seat away from the first limiting member, and the second limiting member is a horizontally positioned spring.

[0041] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0042] Please see Figures 4-7 This application provides the following technical solutions:

[0043] A conversion mechanism for a large downhill slider includes a moving template and a fixed template. A slider mechanism is provided between the moving and fixed templates. The moving template can move toward or away from the fixed template. The relevant structures of the moving and fixed templates can adopt existing technologies, which are not the technical focus of this solution but belong to the application environment of this solution and will not be elaborated here. The main modification of this solution is in the slider mechanism. For ease of description, the opening and closing directions of the moving and fixed templates will be taken as the vertical direction, and the corresponding lateral direction of the moving and fixed templates will be taken as the horizontal direction. The direction of the fixed template toward the product is considered internal, and vice versa.

[0044] The slider mechanism of this solution includes a slider 1 and a sliding seat 2, with one side of the slider 1 positioned corresponding to the undercut position of product 100. Both slider 1 and slider seat 2 can be slidably connected to the fixed template, but their sliding directions are different: slider seat 2 slides horizontally, while slider 1 slides vertically at an angle, and slider seat 2 and slider 1 are linked. The moving template is connected to a linkage component 5, which drives slider seat 2 to slide horizontally. Sliding seat 2 has a groove corresponding to slider 1, and slider 1 is slidably connected to slider seat 2 through the groove. When the moving template moves away from the fixed template, slider 1 moves along the groove on slider seat 2 in a direction away from the undercut position of product 100. The groove on slider seat 2 only needs to allow slider 1 and slider seat 2 to slide relative to each other without separating; for example, a dovetail groove, wedge groove, T-groove, etc., are all acceptable. This solution uses a T-groove structure for slider seat 2, and slider 1 has a T-shaped part corresponding to the T-groove for sliding connection.

[0045] When the moving mold plate moves away from the fixed mold plate, the linkage component 5 can drive the slider 1 away from the undercut position of the product 100 via the slider seat 2. Through this structure, the slider seat 2 serves as the support for the slider 1 and provides a sliding path, allowing the slider 1 to meet the injection molding support requirements of the undercut position with a large downward slope. After injection molding is completed, the linkage component 5 drives the slider seat 2 to move the slider 1 away from the product 100, achieving product demolding.

[0046] Based on the above implementation scheme, this mechanism also includes a first guide assembly 3, which is disposed between the slider 1 and the fixed template, and the slider 1 and the first guide assembly 3 are slidably connected. The function of the first guide assembly 3 is to limit the movement of the slider 1, ensuring that it can move along the limiting path of the two guide structures, the slider seat 2 and the first guide assembly 3. The first guide assembly 3 can take various forms, and its guiding direction only needs to be vertical overall, but the upper end is inclined towards the product 100 and the lower end is inclined towards the slider seat 2. The first guide assembly 3 used in this scheme includes two first pressure blocks, which are inclined blocks and are fixedly connected to the fixed template. The first pressure blocks are slidably connected to the slider 1; the upper end of the first pressure block is set towards the product 100 and the lower end is set towards the slider seat 2. There is a gap between the first pressure block and the fixed template, and the slider 1 has flanges on both sides corresponding to the two first sliders. The flanges are engaged between the first pressure blocks and the fixed template to achieve a slidable connection. The upper end of slider 1 is set to correspond to product 100, the lower end of slider 1 extends to the outer side of the lower end of the first pressure block, and the lower end of slider 1 is slidably connected to slider seat 2. The lower end of slider 1 is the aforementioned "T" shaped part.

[0047] Based on the above implementation scheme, a second guide component 4 is provided corresponding to the slider seat 2. The second guide component 4 is disposed between the slider seat 2 and the fixed template, and the slider seat 2 and the second guide component 4 are slidably connected.

[0048] The second guide component 4 only needs to satisfy the requirement that the limiting slider seat 2 slides horizontally without detaching from the fixed template. This solution provides one implementation of the second guide component 4. The second guide component 4 includes two second pressure blocks, which are fixedly connected to the fixed template and slidably connected to the slider seat 2.

[0049] Two second pressure blocks have horizontal grooves on one side facing the slider seat 2. The slider seat 2 is slidably connected to the second pressure blocks through these grooves, and a lower wear-resistant plate is provided at the bottom of the two second pressure blocks. The bottom surface of the slider seat 2 is in contact with the lower wear-resistant plate. The wear-resistant plate is located at the end of the horizontally outer side of the moving path of the slider seat 2 towards the fixed template.

[0050] Based on the above implementation scheme, the linkage component 5 includes a shovel base 51 and a guide rod 52. The shovel base 51 is fixedly connected to the moving template, and the guide rod 52 is fixedly mounted on the shovel base 51. The shovel base 51 includes a mounting platform with a notch at the bottom to accommodate the slider seat 2. A mounting hole is provided on the mounting platform, and the guide rod 52 is inserted into the mounting hole. It is fixedly connected to the shovel base 51 through the mounting hole. A guide hole is provided on the slider seat 2 corresponding to the guide rod 52, and the guide rod 52 is slidably connected to the slider seat 2 through the guide hole.

[0051] The guide rod 52 is also an inclined rod, with its upper end inclined towards the inside of the moving template and its lower end inclined towards the outside of the moving template. The inclined direction of the guide rod 52 and the first guide assembly 3 are the same, but the inclination angles are different. The guide hole on the slider seat 2 is a corresponding inclined hole.

[0052] When the moving mold plate opens vertically upwards, the slider 2 slides along the second guide component 4 towards the outer side of the fixed mold plate under the coordinated action of the guide rod 52 and the slider seat 2. During the sliding process of the slider seat 2, due to the guiding effect of the first guide component 3 of the slider seat 2, the slider 1 moves away from the undercut position of the product 100 in an inclined downward direction, which will not affect other structures of the product 100 and will not affect the demolding of the product 100.

[0053] Based on the above implementation plan, see Figure 7 To ensure the controllability of the sliding block 2's movement, this mechanism also includes a limiting component to limit the sliding block 2. The limiting component includes a first limiting member 6 and a second limiting member 7. The first limiting member 6 is fixedly connected to the fixed template and is positioned on the horizontally outer side of the sliding block 2 facing the fixed template. The first limiting member 6 is a limiting post, which blocks the movement of the sliding block 2. The second limiting member 7 is positioned on the side of the sliding block 2 away from the first limiting member 6, that is, on the inner side of the sliding block 2. The second limiting member 7 is a horizontally positioned spring. One end of the second limiting member 7 is connected to the side facing the sliding block 2, and the other end can be connected to the fixed template or the first pressure block. Through the second limiting member 7, regardless of whether the sliding block 2 slides outwards or inwards, the second limiting member 7 can provide a certain limiting effect, especially when the sliding block 2 moves inwards, the limiting effect of the second limiting member 7 is stronger.
