Description

Technical Field

[0001] This utility model relates to the field of thermoforming processing technology, specifically a thermoforming mold structure. Background Technology

[0002] Thermoforming is a specialized plastic processing method that shapes thermoplastic sheets into various products. The sheet is clamped in a frame and heated to a softened state. Under external force, it is forced to conform to the mold surface to achieve a shape similar to the mold surface. After cooling and setting, it is trimmed to obtain the finished product. This process is also used in rubber processing. In recent years, thermoforming has made new advancements, such as continuous production technology from extruded sheets to thermoforming.

[0003] In existing thermoforming processes, the mold is set on the base frame (e.g.) Figure 1 As shown in the diagram, due to the large internal space of the base frame, the actual internal space is V1 + V2 (V1 is the inherent internal space of the mold, and V3 is the internal space of the mold vacuum chamber). When the equipment is evacuated, the vacuum pump needs to extract more air to achieve a better vacuum level, which increases energy consumption and requires the vacuum pump to have high power.

[0004] In view of this, there is an urgent need for a thermoforming mold structure. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model solves the problem using the following technical structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A thermoforming mold structure includes: a mold, a base plate, a support member, and a vacuum interface assembly. The mold is disposed on the base plate, and the base plate has a through hole communicating with the inner cavity of the mold. The support member is disposed at the bottom of the base plate.

[0008] The vacuum interface assembly is located at the bottom of the base plate, and the top opening of the vacuum interface assembly is adapted to the through hole.

[0009] A further feature is that,

[0010] The vacuum interface assembly is a flange joint.

[0011] The flange joint is fixed to the base plate by bolts.

[0012] The vacuum interface assembly is a galvanized pipe.

[0013] The galvanized pipe is inserted into the through hole.

[0014] The galvanized pipe is threaded onto the base plate.

[0015] Two support members are provided, and the two support members are respectively provided on both sides of the through hole.

[0016] The support is made of channel steel.

[0017] The channel steel has several mounting holes at both the top and bottom.

[0018] The base plate is an aluminum plate.

[0019] The above-described structure of this utility model can achieve the following beneficial effects:

[0020] In use, the mold is placed on the base plate, and the base plate is supported on the equipment by the support members, so that the through hole on the base plate is connected to the inner cavity of the mold. The vacuum equipment is connected to the inner cavity of the mold through the vacuum connector assembly. In use, the vacuum equipment directly evacuates the inner cavity of the mold through the vacuum interface assembly. The space required for evacuation is smaller, the evacuation efficiency is higher, and the power requirement of the vacuum equipment is lower. Attached Figure Description

[0024] 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. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0025] It should be noted that the terms "comprising" and "having" and any variations thereof in the specification, claims and accompanying drawings of this utility model are intended to cover non-exclusive inclusion. For example, a process, method, apparatus, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such processes, methods, products or devices.

[0026] The following is in conjunction with the appendix Figure 2 This application will be described in further detail.

[0027] refer to Figure 2 The thermoforming mold structure shown includes: a mold 1, a base plate 2, a support member 3, and a vacuum interface assembly 4. The mold 1 is disposed on the base plate 2, and the base plate 2 is provided with a through hole 21 that communicates with the inner cavity of the mold 1. The support member 3 is disposed at the bottom of the base plate 2.

[0028] Vacuum interface assembly 4 is located at the bottom of base plate 2, and the top opening of vacuum interface assembly 4 is adapted to through hole 21.

[0029] Based on the above structure, in use, the mold 1 is placed on the base plate 2, and the base plate 2 is supported on the equipment by the support member 3, so that the through hole 21 on the base plate 2 is connected to the inner cavity of the mold 1. The vacuum equipment is connected to the inner cavity of the mold 1 through the vacuum connector assembly 4. In use, the vacuum equipment directly evacuates the inner cavity of the mold 1 through the vacuum interface assembly 4. The space required for evacuation is smaller, the evacuation efficiency is higher, and the power requirement of the vacuum equipment is lower.

[0030] Further optimization involves the vacuum interface assembly 4 being either a flange joint or a galvanized pipe. In actual use, the configuration is adapted to the type of connector used in the vacuum equipment. If a flange joint is selected as the vacuum interface assembly 4, it is fixed to the base plate 2 with bolts. If a galvanized pipe is selected as the vacuum interface assembly 4, it is inserted into the through hole 21. The galvanized pipe can be fixed to the base plate 2 by either threaded connection or snap-fit ​​connection.

[0031] like Figure 2 As shown, at least two support members 3 are provided. The two support members 3 are respectively provided on both sides of the through hole 21 to support the base plate 2 from both sides, making the mold 1 more stable during processing. The support members 3 can be made of channel steel, and in order to facilitate connection and fixation, several mounting holes are provided on the top and bottom of the channel steel to achieve quick adjustment and fixation.

[0032] A further optimization is that, since the conventional base plate 2 is made of iron plate, which is prone to rust, the base plate 2 in this embodiment is made of aluminum plate.

[0033] In summary, during use, the mold 1 is placed on the base plate 2, and the base plate 2 is supported on the equipment by the support member 3, so that the through hole 21 on the base plate 2 is connected to the inner cavity of the mold 1. The vacuum equipment is connected to the inner cavity of the mold 1 through the vacuum connector assembly 4. During use, the vacuum equipment directly evacuates the inner cavity of the mold 1 through the vacuum interface assembly 4. The space required for evacuation is smaller, which reduces energy consumption, improves evacuation efficiency, and requires lower power from the vacuum equipment.

[0034] The above are merely preferred embodiments of this application, and the present invention is not limited to the above embodiments. It is understood that other improvements and variations that can be directly derived or conceived by those skilled in the art without departing from the spirit and concept of the present invention should be considered to be included within the protection scope of the present invention.
