Description

Technical Field

[0001] This utility model relates to the technical field of vacuum forming of automotive interiors, and in particular to a vacuum forming mold for automotive interior processing. Background Technology

[0002] Interior color and texture design play a crucial role in the overall interior design, directly determining the final sensory effect of the entire interior. In the automotive industry, the use of thermoplastic elastomers in interior plastic components creates a warm and comfortable environment, and the texture directly influences consumers' visual judgment of a vehicle's comfort level.

[0003] A search revealed Chinese patent publication number CN221793770U, which discloses a vacuum forming mold for automotive interior parts with etched texture. The mold comprises an upper mold and a lower mold, arranged from top to bottom. An upper pressure plate is installed on the inner side of the upper mold, and a lower mold cavity is provided within the lower mold. An upper mold cavity, adapted to the lower mold cavity, is located on the inner bottom of the upper pressure plate. Several suction holes are provided on the lower mold cavity, and the bottom of each suction hole is connected to a lower air collection cavity via an air outlet pipe. The lower mold cavity is higher on both sides and lower in the middle. The bottom of the air collection cavity in the middle of the lower mold cavity is connected to the lower air inlet cavity.

[0004] Existing vacuum forming molds for automotive interior parts typically employ a single cooling method (such as natural cooling or simple water cooling), resulting in rapid mold temperature rise and frequent shutdowns for cooling, which severely impacts production efficiency.

[0005] In addition, existing demolding and material collection processes rely on complex devices such as suction cups and mechanical claws, which are costly and require strict positioning accuracy. In particular, for irregularly shaped parts, the picking position needs to be adjusted multiple times, making the operation cumbersome.

[0006] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a vacuum forming mold for automotive interior processing, making it more valuable for industrial use. Utility Model Content

[0034] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0035] The first embodiment of this utility model:

[0036] like Figure 1 An embodiment of a vacuum forming mold for automotive interior processing mainly includes a mold base 1, a pressure table 3, a pressure plate 4, and a heat exchange unit.

[0037] A mold cavity 2 for forming the workpiece is provided on the inner side of the mold base 1. The shape of the mold cavity 2 can be adapted to the requirements of the workpiece. Several adsorption holes for adsorbing the workpiece are designed in the mold cavity 2, and an air passage structure adapted to the adsorption holes is installed on the mold base 1 on the outside of the mold cavity 2 (the above is the conventional design of the adsorption structure in the mold cavity in this field, which is not shown in the figure).

[0038] A pressure plate 3 is installed on the mold base 1 on the outer side of the top of the mold cavity 2. The pressure plate 3 protrudes from the outer side of the mold base 1. The area of ​​the workpiece that does not need to be processed is placed on the pressure plate 3 and pressed by the pressure plate 4 located above the pressure plate 3.

[0039] like Figure 3 The pressure plate 4 is a hollow frame structure used to place on the pressure platform 3 and to press the outer side of the workpiece located above the pressure platform 3. Lifting plate mounting grooves 12 are designed on both the left and right sides of the bottom of the pressure plate 4 to be adapted to the lifting mechanism 10 below.

[0040] like Figure 2 A lifting cavity 9 is provided on the pressure plate 3 directly below the lifting plate mounting groove 12, and a lifting mechanism 10 is installed at the bottom of the pressure plate 3 below the lifting cavity 9.

[0041] like Figure 4The lifting mechanism 10 includes a lifting cylinder mounting bracket 14 installed at the bottom of the pressure platform 3. A lifting cylinder 15 is installed on the lifting cylinder mounting bracket 14. The piston rod at the top of the lifting cylinder 15 drives the upper lifting plate 16 to move up and down. The lifting plate 16 is connected to the lifting plate mounting groove 12 directly above, thereby driving the upper pressure plate 4 to move up and down, thereby realizing the process of pressing or releasing the pressing of the workpiece located above the pressure platform 3.

[0042] Several positioning posts 13 are installed at the bottom of the pressure plate 4, and positioning holes 11 adapted to the positioning posts 13 are opened on the pressure platform 3 directly below the positioning posts 13. Through the mutual adaptation (one-to-one correspondence) between the positioning posts 13 and the positioning holes 11, the pressure plate 4 can be well guided and positioned during its up and down movement. In addition, to avoid affecting the workpiece, the design position of the positioning posts 13 and the positioning holes 11 usually needs to avoid the workpiece. In some cases, the positioning posts 13 can also be designed as a detachable structure to facilitate the above functions.

[0043] In addition, a structure that can be connected to the workpiece is installed at the bottom of the pressure plate 4, such as an adhesive structure or a snap-fit ​​structure, so that the pressure plate 4 can lift the workpiece together during the lifting process.

[0044] like Figure 1 The heat exchange unit mainly includes a bottom heat exchange structure and a side heat exchange structure:

[0045] The bottom heat exchange structure mainly includes a heat exchange tube cavity 5 and heat exchange tubes 6 installed inside the heat exchange tube cavity 5.

[0046] Specifically, a heat exchange tube cavity 5 is provided on the mold base 1 at the bottom of the mold cavity 2, distributed along a serpentine structure, and a heat exchange tube 6 is installed inside the heat exchange tube cavity 5. In some cases, in order to avoid interference between the heat exchange tube cavity 5 and the mold cavity 2, the heat exchange tube cavity 5 is located below the mold cavity 2, and is designed to be close to but not in contact with it.

[0047] In addition, the heat exchange tube 6 has a flat tubular structure and fits tightly with the upper mold cavity 2, increasing the contact area and improving the heat transfer efficiency.

[0048] The inlet and outlet of the heat exchange tube 6 extend from both sides of the mold base 1, so that the heat exchange liquid medium flows in a serpentine direction and carries away the heat of the mold body evenly.

[0049] The side heat exchange structure mainly includes an exhaust fan assembly 7 and a heat exchange assembly 8.

[0050] Specifically, an exhaust assembly 7 connected to the mold cavity 2 is installed on the rear side of the mold base 1, and a heat exchange assembly 8 connected to the mold cavity 2 and adapted to the exhaust assembly 7 is installed on the front side of the mold base 1. The exhaust assembly 7 is used to extract the air from the mold cavity 2, and then the heat exchange assembly 8 is used to exchange heat with the external air before it enters the mold cavity 2.

[0051] like Figure 5 The ventilation assembly 7 includes a ventilation box 17 installed on the mold base 1, a fan 18 installed inside the ventilation box 17, an exhaust port 19 opened on the rear side of the ventilation box 17, and an air outlet 20 connected to the mold cavity 2 opened on the front side of the ventilation box 17.

[0052] During operation, the exhaust assembly 7 uses a fan 18 (which may be a centrifugal fan, etc.) to draw out the air in the mold cavity 2 through the air outlet 20 and the exhaust port 19 and discharge it to the outside.

[0053] To prevent dust from entering the mold cavity 2, dustproof nets 21 are installed at both the exhaust port 19 and the outlet 20.

[0054] like Figure 6 The heat exchange assembly 8 includes a heat exchange box 22 mounted on the mold base 1, a heat exchanger 23 installed inside the heat exchange box 22, an air outlet 24 connected to the mold cavity 2 on the rear side of the heat exchange box 22, and an air inlet 25 on the front side of the heat exchange box 22.

[0055] During operation, the air in the mold cavity 2 is drawn away by the exhaust assembly 7, which reduces the air pressure in the mold cavity 2. This forces outside air to enter from the air inlet 25 of the heat exchange box 22 on the other side, and after heat exchange by the heat exchanger 23, it enters the mold cavity 2 through the air outlet 24.

[0056] To prevent dust from entering the mold cavity 2, dustproof nets 21 are installed at both the air inlet 24 and the air outlet 25.

[0057] In addition, heat exchange is generally not required during the adsorption process of the workpiece. At this time, the connection between the exhaust box 17 and the heat exchange box 22 and the outside world is sealed by a sealing cover.

[0058] The second embodiment of this utility model:

[0059] Based on the first embodiment described above, the installation position of the exhaust component 7 remains unchanged, and heat exchange components 8 can be installed on both the left and right sides of the mold base 1 to further improve the heat exchange efficiency.

[0060] Alternatively, exhaust assembly 7 and heat exchange assembly 8 can be installed on the left and right sides of mold base 1 respectively.

[0061] The third embodiment of this utility model:

[0062] An air blowing hole can also be installed at the bottom of the mold cavity 2, and an air passage structure adapted to the air blowing hole can be installed on the mold base 1 outside the mold cavity 2. The air blowing hole can help realize the demolding process of the workpiece on the mold cavity 2.

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0064] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0065] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
