Description

Technical Field

[0001] This invention belongs to the field of automotive parts manufacturing technology, specifically relating to a sealing strip forming mold and a demolding method. Background Technology

[0002] Automotive sealing strips are key components installed on car doors, windows, sunroofs, trunks, and engine compartments. They serve multiple functions, including shock absorption, waterproofing, dustproofing, sound insulation, and decoration, playing a vital role in improving driving comfort and protecting the vehicle body.

[0003] like Figure 10 , Figure 11 As shown, this sealing strip has a relatively complex structure, with an overall undulating curved shape, two large-radius corners, two undercut elongated holes in the middle of the inner surface cavity, and one undercut short hole at the end. The inner surface cavity also has numerous ribs. Existing molds struggle to form such complex sealing strips, primarily because the mold's forming components cannot be effectively combined to create the intricate inner and outer surface cavities. Furthermore, during demolding, the presence of multiple undercut structures makes conventional demolding methods prone to damage or failure to release the product smoothly. Therefore, a new mold needs to be designed to accommodate the forming of such complex sealing strips, along with corresponding demolding steps, to address the problems of insufficient forming capacity and difficult demolding in existing technologies. Summary of the Invention

[0004] The present invention aims to solve the problems in the prior art for sealing strips with complex internal and external morphology, especially those with multiple undercut structures and meandering curves, where the mold structure design is difficult, the demolding process is cumbersome, and the product is easily damaged.

[0005] This invention can be achieved through the following technical solutions: A sealing strip forming mold, comprising: A fixed base on which a first molded component and a second molded component are fixedly mounted; A middle sleeve plate is vertically and flexibly disposed above the base. A slidable third forming component is disposed on the middle sleeve plate, and a fourth forming component is fixedly disposed on the middle sleeve plate. The fifth molding component is rotatably disposed on the middle sleeve plate, and the fifth molding component can be raised and lowered with the middle sleeve plate, and the fourth molding component is located below the fifth molding component; A slider assembly includes a first slider, a second slider, and a third slider. The first slider, the second slider, and the third slider are all slidably disposed on the middle sleeve plate and can rise and fall with the middle sleeve plate. The ends of the first slider, the second slider, and the third slider are respectively configured as a first shape, a second shape, and a third shape. An upper template is vertically and vertically positioned above the slider assembly, and the upper template is provided with a feed inlet; When the mold is closed, the first molding part, the second molding part, the third molding part, the fourth molding part, the fifth molding part, the first molded part, the second molded part, and the third molded part together form a molding cavity.

[0006] Preferably, when the mold is closed, the fifth molding part, the third molding part, and the third molded part are connected end to end in sequence, the first molding part is located below the third molding part, and the second molding part is located below the third molded part; the fifth molding part, the third molding part, the third molded part, the fourth molding part, the first molding part, and the second molding part together constitute an inner molding part for molding the inner surface of the sealing strip; the first molded part and the second molded part together constitute an outer molding part for molding the outer surface of the sealing strip.

[0007] Preferably, the demolding direction of the first slider is a first direction, the demolding direction of the second slider is a second direction, the first direction and the second direction are collinear and opposite, and the demolding direction of the third slider is a third direction, which is set at an acute angle to the first direction.

[0008] Preferably, it also includes a driving component, and the first slider and the second slider are both linked to the driving component. The driving component can simultaneously drive the first slider and the second slider to move closer to each other or further away from each other.

[0009] Preferably, the middle sleeve plate is linked to the drive assembly, and the drive assembly can drive the middle sleeve plate to rise and fall.

[0010] Preferably, the drive assembly includes a hydraulic cylinder, a first drive plate, a rotating component, and a first linkage plate. The first drive plate is fixedly connected to the drive end of the hydraulic cylinder. The middle part of the rotating component is rotatably disposed on the base. One end of the rotating component is linked to the first drive plate, the first linkage plate is linked to the other end of the rotating component, and the first slider is linked to the first linkage plate.

[0011] Preferably, the drive assembly further includes a second drive plate and a second linkage plate. The second drive plate is fixedly connected to the drive end of the hydraulic cylinder, the second linkage plate is fixedly connected to the second drive plate, and the second slider is linked to the second linkage plate.

[0012] Preferably, the second drive plate is provided with a first inclined surface for driving the middle sleeve plate to rise and fall, a drive column is fixedly provided below the middle sleeve plate, and a second inclined surface is provided at the bottom end of the drive column. The first inclined surface can abut against and connect with the second inclined surface.

[0013] Secondly, a demolding method is also provided, which is applied to the above-mentioned sealing strip forming mold, including the following steps: S1: After the molding cavity has cooled down, control the upper template to rise; S2: Control the drive component to move, which simultaneously drives the first slider and the second slider to move away from each other in the first direction and the second direction, respectively; S3: The drive component continues to move, thereby driving the middle sleeve plate to rise; S4: Manually drive the third slider to move away from the molding cavity; S5: First, manually fold the sealing strip after it has been formed at the third forming part, and then manually drive the third forming part to move away from the forming cavity; S6: Manually drive the fifth molding component to rotate, and the fifth molding component drives the formed sealing strip to rotate; S7: Manually separate the sealing strip from the fifth molded part.

[0014] Preferably, in step S3, the lifting of the middle sleeve plate can simultaneously lift the third forming part, the fourth forming part, the fifth forming part, the first slider, the second slider, and the third slider.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. By setting multiple molding parts and sliders that can move independently or in conjunction, complex molding cavities can be formed. In particular, it can accurately mold the inner and outer surfaces of sealing strips with meandering curves, large arc corners, and multiple undercut holes and ribs, solving the problem that existing molds are difficult to mold such complex structures.

[0016] 2. The mold structure is ingeniously designed. The drive components enable synchronous driving of the first and second sliders and sequential driving of the centering plate, resulting in a high degree of automation, which helps improve the efficiency of mold closing and initial demolding stages.

[0017] 3. Different demolding methods were designed for different undercut structures: For long undercut holes formed by the third slider, direct sliding demolding was used; for long undercut holes formed by the third molding part, the product was folded over first, followed by forced demolding; for short undercut holes formed by the fifth molding part, a final rotation demolding method was used. This step-by-step, differentiated demolding method can systematically release the constraints of each undercut structure on the product, effectively avoiding damage to the complex sealing strip during the demolding process.

[0018] 4. The third and fifth molding parts are used to mold two large-radius corners respectively. Their sliding and rotating design allows them to detach smoothly from the corners of the product, ensuring the integrity of the molding quality of the corners. Attached Figure Description

Detailed Implementation

[0032] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings to further illustrate the technical solutions of the present invention. However, the present invention is not limited to these embodiments. Example 1

[0033] like Figures 1-11 As shown, this embodiment provides a molding die for forming a sealing strip 700, which is used to form an automotive sealing strip 700 with a complex internal and external morphology. The die includes a base 100, a middle sleeve plate 200, an upper template 400, multiple forming parts, and a slider assembly.

[0034] The base 100 is fixedly installed as the supporting foundation for the entire mold. The first molding part 110 and the second molding part 120 are fixedly installed on the base 100. The first molding part 110 and the second molding part 120 are mainly used to form multiple ribs 730 in the inner surface cavity of the sealing strip 700. Their shapes match the ribs 730, which helps to improve the structural strength and functionality of the sealing strip 700.

[0035] like Figures 2-5 As shown, the middle sleeve plate 200 is positioned above the base 100 and can move up and down relative to the base 100. A third molding component 210 is slidably mounted on the upper surface of the middle sleeve plate 200 via a guide rail or similar structure, allowing the third molding component 210 to slide horizontally along a specific direction on the middle sleeve plate 200. Simultaneously, a fourth molding component 220 is fixedly mounted on the middle sleeve plate 200. The fourth molding component 220 and the third molding component 210 together form part of the inner surface cavity of the sealing strip 700. A fifth molding component 230 is rotatably mounted on the middle sleeve plate 200 via a pivot. The fifth molding component 230 can rotate around its pivot and, because it is mounted on the middle sleeve plate 200, it can move up and down with the middle sleeve plate 200. The fourth molding component 220 is positioned below the fifth molding component 230, and the two fit tightly together during mold closing.

[0036] like Figures 2-6 As shown, the slider assembly is mounted on the middle sleeve plate 200 and includes a first slider 310, a second slider 320, and a third slider 330. These three sliders are slidably mounted on the middle sleeve plate 200 via structures such as grooves or guide rails, and because they are mounted on the middle sleeve plate 200, they can rise and fall together with the middle sleeve plate 200. The ends of the first slider 310, the second slider 320, and the third slider 330 facing the mold cavity are precision machined to form a first molded portion 311, a second molded portion 321, and a third molded portion 331, respectively. The third molded portion 331 is used to form an undercut elongated hole 710 in the inner surface cavity of the sealing strip 700.

[0037] like Figure 1 As shown, the upper mold plate 400 is positioned above all the slider assemblies and can be raised and lowered by the power mechanism of the injection molding machine. A feed port 410 is provided at the center or a suitable location of the upper mold plate 400 for injecting molten plastic material.

[0038] When the mold closes, all molded parts and shapes work together. Specifically, the fifth molded part 230, the slidable third molded part 210, and the third shape 331 of the third slider 330 are connected end to end to form the inner surface cavity of a winding, large-arc corner section of the sealing strip 700. The first molded part 110 is located directly below the third molded part 210, and the second molded part 120 is located below the third shape 331. Together with the fourth molded part 220, the fifth molded part 230, the third molded part 210, and the third shape 331, they form the inner molding part for molding the complex inner surface of the entire sealing strip 700. This inner molding part can accurately replicate all the details of the inner surface of the sealing strip 700, including the ribs 730 and the two undercut elongated holes 710 and one undercut short hole 720. At the same time, the first shape 311 of the first slider 310 and the second shape 321 of the second slider 320 interlock to form the outer molding part for molding the outer surface of the sealing strip 700. Finally, the inner and outer molding parts come together to form a closed molding cavity that perfectly matches the shape of the target sealing strip 700. The third molding part 210 is used to mold another undercut elongated hole 710 and another large-radius corner on the inner surface of the sealing strip 700, while the fifth molding part 230 is used to mold an undercut short hole 720 and a corresponding large-radius corner on the inner surface of the sealing strip 700.

[0039] To efficiently drive the sliders, the mold also includes a drive assembly. Both the first slider 310 and the second slider 320 are linked to this drive assembly. The drive assembly can simultaneously drive the first slider 310 and the second slider 320 to move closer together (during mold closing) or further apart (during demolding) along a straight line. The demolding direction of the first slider 310 is defined as a first direction, and the demolding direction of the second slider 320 is defined as a second direction. The first and second directions are collinear and opposite in direction. The demolding direction of the third slider 330 is defined as a third direction, which forms an acute angle with the first direction. This angle setting adapts to the orientation of the local structure of the sealing strip 700, facilitating the smooth sliding of the third part 331 out of the formed undercut elongated hole 710.

[0040] Furthermore, the middle sleeve plate 200 is also linked to the drive assembly. The working process of the drive assembly is sequential: it first drives the first slider 310 and the second slider 320 to move away from each other, completing the mold opening of the outer forming part; then it continues to move, thereby driving the middle sleeve plate 200 to rise as a whole. The rising of the middle sleeve plate 200 will drive all the components installed on it, including the third forming part 210, the fourth forming part 220, the fifth forming part 230, the first slider 310, the second slider 320 and the third slider 330, to rise together, realizing the initial mold opening.

[0041] like Figure 7As shown, in a specific driving scheme, the driving assembly includes a hydraulic cylinder 510, a first driving plate 520, a rotating component 530, and a first linkage plate 540. The driving end of the hydraulic cylinder 510 is fixedly connected to the first driving plate 520. The middle part of the rotating component 530 is rotatably mounted on the base 100 via a rotating shaft. One end of the rotating component 530 is linked to the first driving plate 520 via an inclined plane, roller, or connecting rod, and the other end is linked to the first linkage plate 540, which in turn is linked to the first slider 310. When the hydraulic cylinder 510 drives the first driving plate 520 to move linearly, it drives the rotating component 530 to rotate, thereby converting the rotational motion into the linear motion of the first slider 310 through the first linkage plate 540.

[0042] like Figure 8 As shown, the drive assembly may further include a second drive plate 550 and a second linkage plate 560. The second drive plate 550 is also fixedly connected to the drive end of the hydraulic cylinder 510, and the second linkage plate 560 is fixedly connected to the second drive plate 550. The second slider 320 is linkedly connected to the second linkage plate 560. In this way, a linear output from the hydraulic cylinder 510 can simultaneously and synchronously drive the first drive plate 520 and the second drive plate 550, thereby causing the first slider 310 and the second slider 320 to move synchronously in opposite directions. The structure is compact and the drive is reliable.

[0043] like Figure 9 As shown, to achieve automatic lifting and lowering of the middle sleeve plate 200 after driving the slider, an inclined first slope 551 is provided on the second drive plate 550. A drive column 600 is fixedly installed below the middle sleeve plate 200, and a second slope 610 matching the first slope 551 is machined at the bottom end of the drive column 600. When the hydraulic cylinder 510 drives the second drive plate 550 to a certain position, causing the slider to complete the mold opening action, the first slope 551 begins to contact the second slope 610 at the bottom end of the drive column 600 and relative sliding occurs. Utilizing the effect of the slope, the continued horizontal movement of the second drive plate 550 can be converted into an upward thrust on the drive column 600, thereby driving the middle sleeve plate 200 to rise smoothly, realizing the sequential automation of the demolding action. Example 2

[0044] This embodiment provides a demolding method for the sealing strip 700 forming mold described in Embodiment 1.

[0045] The method includes the following steps: S1: After the molten material in the molding cavity has cooled and solidified sufficiently, control the injection molding machine to lift the upper mold plate 400 upwards, so that the feed port 410 is separated from the molded product.

[0046] S2: Activate the drive assembly, such as the hydraulic cylinder 510. The drive assembly simultaneously drives the first slider 310 and the second slider 320 to move in the first direction and the second direction respectively, causing them to move away from each other. This step opens the outer forming portion formed by the first part 311 and the second part 321, exposing the outer surface of the sealing strip 700.

[0047] S3: The drive assembly continues to move in the original direction. Since the drive assembly and the middle sleeve plate 200 are linked through the inclined plane mechanism, the continued movement of the drive assembly will drive the middle sleeve plate 200 to rise. The lifting of the middle sleeve plate 200 will cause all components mounted on it to rise simultaneously, including the third molding part 210, the fourth molding part 220, the fifth molding part 230, the first slider 310, the second slider 320, and the third slider 330, thereby separating the entire inner molding part from the first molding part 110 and the second molding part 120 fixed on the base 100, completing the main mold opening action of the mold.

[0048] S4: The operator manually drives the third slider 330 to slide along a predetermined third direction (at an acute angle to the first direction) and move it away from the molding cavity. This action causes the third part 331 of the third slider 330 to be pulled out from the undercut elongated hole 710 it has formed.

[0049] S5: Due to structural limitations, special handling is required for the other undercut elongated hole 710 and the large-radius corner formed by the third molding part 210. The operator first manually and gently folds the portion of the sealing strip 700 already formed at the third molding part 210 to induce a certain degree of elastic deformation, thereby creating a demolding space between the undercut portion and the third molding part 210. Then, the operator manually drives the third molding part 210, causing it to slide along the guide rail on the middle sleeve plate 200 in a direction away from the molding cavity, achieving forced demolding.

[0050] S6: The operator manually drives the fifth molded part 230 to rotate around its axis. The rotation of the fifth molded part 230 will cause the sealing strip 700 part formed on it (especially the undercut short hole 720 and the large arc corner part) to move together, thereby turning the part out of the mold.

[0051] S7: Finally, the operator manually removes the sealing strip 700 product, which has been completely detached from all mold components, from the fifth molding part 230, completing the entire demolding process.

[0052] Working principle: The core of this demolding method lies in its step-by-step demolding strategy, which combines automated drive with manual operation and adheres to a strict sequence, targeting the undercut structures at different positions and depths on the sealing strip 700. First, automated actions open the outer mold and lift the inner mold body, resolving demolding of most structures. Then, for the three different undercut structures, differentiated manual operations are employed in order of increasing demolding resistance: direct sliding, forced demolding after folding, and rotational demolding. This sequence ensures that no additional pulling force is applied to subsequent undercut parts before the constraint of the previous undercut is released. The differentiated operation methods adapt to the geometric characteristics of different undercut structures, maximizing the use of material elasticity. While ensuring successful demolding, it effectively avoids product tearing, deformation, or even breakage caused by forced demolding. This method is particularly suitable for demolding the automotive sealing strip 700 after molding, which has complex structures and high precision requirements.

[0053] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0054] Furthermore, in this invention, descriptions involving terms such as "first," "second," and "a" are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0055] In this invention, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0056] Furthermore, the technical solutions of the various embodiments of the present invention can be combined with each other, but only if they are feasible for those skilled in the art. If the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.
