Description

Technical Field

[0001] The utility model relates to the field of material pressing equipment, in particular to a material pressing die. Background Art

[0002] In existing material processing lines, profiling often involves integrating multiple process steps. As the core component of the profiling process, the mold's structural design directly impacts production efficiency and cost control. Existing profiling mold systems typically utilize a split-body architecture, where the material is positioned from a front conveyor line via a transfer mechanism to the mold cavity for profiling. After profiling, the formed product must be transferred again via the transfer mechanism to a rear conveyor line. The separation of the mold and material carrier necessitates complex transfer mechanisms, increasing equipment investment and maintenance costs. The multiple transfer operations also extend production cycle times, hindering the efficiency of automated production lines. Furthermore, some designs have attempted to utilize the material tray directly as the lower mold component. While this reduces the number of transfer steps, these trays, which must withstand the profiling pressure, are often made of metal. However, metal trays are heavy, making transport and handling more difficult. Furthermore, their high processing costs and limited flexibility make them difficult to adapt to the rapid turnover requirements of efficient automated production lines. Therefore, how to simplify the material flow path and reduce the weight of the carrier while ensuring profiling accuracy in mold design remains a pressing technical challenge. Utility Model Content

[0003] In view of the above problems existing in the prior art, the utility model provides a lightweight, low-cost and easy-to-use material pressing die.

[0004] The technical solution adopted by the utility model is as follows: a material pressing mold, including an upper mold, a lower mold, and a material carrier, wherein the material carrier includes a bottom plate, a pressure plate and a plurality of independent material supporting units; the material supporting unit has a sunken concave cavity, and a material is placed in the concave cavity of each material supporting unit, and a flange is provided on the upper part of the material supporting unit, and the bottom plate and the pressure plate are respectively provided with through grooves whose number is the same as the number of material supporting units, and the concave cavities of the material supporting units are correspondingly provided with the through grooves, and the bottom plate and the pressure plate are fastened to clamp the flanges of the material supporting units therebetween to fix the material supporting units; the lower mold includes a lower template and a plurality of lower modules fixed on the lower template corresponding to the material supporting units, and the bottom shape of the material supporting unit is matched with the upper surface of the lower module; the upper mold includes an upper template and a plurality of upper modules fixed on the upper template corresponding to the material supporting units, and the upper module matches the concave cavity of the material supporting unit, and the material supporting unit is made of lightweight material.

[0005] Furthermore, the bottom plate and the pressing plate are both strip-shaped plates, and the multiple through slots on the bottom plate and the pressing plate are evenly spaced and arranged in a row along the length direction.

[0006] Furthermore, the material carrier is composed of multiple groups of independent bottom plate-pressing plate combination units spliced ​​in parallel, and each row of material supporting units is arranged in a two-dimensional array as a whole after splicing.

[0007] Furthermore, the bottom of the concave cavity of the material supporting unit, the top working surface of the lower module, and the bottom pressing surface of the upper module are all S-shaped profiles with matching shapes.

[0008] Furthermore, the top working surface of the lower module and the bottom pressing surface of the upper module are provided with concave and convex patterns.

[0009] Furthermore, the bottom of the material supporting unit has a through hole that is smaller than the outer dimensions of the supported material.

[0010] Furthermore, the material supporting unit is integrally formed from thermoplastic plastic by a vacuum forming process, and the wall thickness of the material supporting unit is 0.3 to 1 mm.

[0011] The beneficial effects of the present invention are:

[0012] (1) The utility model directly embeds a lightweight material carrier into the mold system. The material always stays in the carrier during the entire process from front conveying, pressing processing to rear conveying. The material does not need to be transferred throughout the process. When the mold is closed, the carrier synchronously serves as the positioning carrier of the upper and lower molds, eliminating the frequent transfer operations in traditional processes, making the flow of materials between pressing and the previous and next processes smoother, simplifying the assembly line structure, shortening the production cycle, and being particularly suitable for high-cycle automated production lines;

[0013] (2) The material support unit is made of lightweight materials (such as thermoplastics), which greatly reduces the overall weight, reduces transportation energy consumption and equipment wear, and reduces processing and maintenance costs. Compared with traditional metal trays, its lightweight characteristics also improve the flow efficiency of the carrier in the assembly line;

[0014] (3) The material carrier, upper mold and lower mold all adopt a modular structure, which can quickly adjust the layout according to different material specifications, enhancing the versatility and flexibility of the mold, while simplifying the installation and maintenance process and further reducing the cost of use.

[0015] Through the above-mentioned mold design innovation, the utility model simplifies the process flow and reduces production costs, while providing an efficient and flexible pressing solution for high-beat automated production lines. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] like Figure 1 As shown, a material pressing mold of this embodiment includes an upper mold 1, a material carrier 2, and a lower mold 3. The material carrier 2 is loaded with material 4 via a loading system and then proceeds along the assembly line through the pre-processing section before entering the pressing station. The upper mold 1 and lower mold 3 close together to press the material 4 on the material carrier 2. After pressing, the material does not need to be transferred; the material carrier 2 directly carries the molded product to the subsequent process.

[0024] like Figure 1 、 Figure 2 、 Figure 5 As shown, the material carrier 2 of this embodiment includes a base plate 203, a pressure plate 201, and multiple independent material support units 202. The material support units 202 have recessed cavities, each of which houses a corresponding piece of material 4. The base plate 203 and the pressure plate 201 serve as the foundation of the material carrier 2. Each base plate 203 and the pressure plate 201 are provided with through slots, the same number as the number of material support units 202. The concave cavities of the material support units 202 correspond to the through slots. The upper portions of the material support units 202 have flanges. The base plate 203 and the pressure plate 201 are fastened together, clamping the flanges of the material support units 202 between them to secure the material support units 202. The material support units 202 are made of lightweight materials.

[0025] like Figure 3-Figure 5As shown, the lower mold 3 of this embodiment includes a lower mold plate 301 and a plurality of lower modules 302 fixed on the lower mold plate 301 corresponding to the material supporting units 202. The lower mold 3 serves as a supporting base, and the bottom shape of the material supporting unit 202 fits the upper surface of the lower module 302. The upper mold 1 includes an upper mold plate 101 and a plurality of upper modules 102 fixed on the upper mold plate 101 corresponding to the material supporting units 202. The upper modules 102 match the concave cavities of the material supporting units 202. During pressing, the material supporting unit 202 carries the material 4 and is placed on the lower module 302, supported by the lower mold 3, and then the upper mold 1 presses down to complete the pressing process of the material 4.

[0026] In this embodiment, the bottom of the concave cavity of the material support unit 202, the top working surface of the lower module 302, and the bottom pressing surface of the upper module 102 all have matching S-shaped profiles, resulting in a uniform appearance of the material after profiling. Furthermore, the top working surface of the lower module 302 and the bottom pressing surface of the upper module 102 can be provided with concave and convex patterns to create a specific texture on the material's profiling surface.

[0027] As a preferred embodiment of this embodiment, both the base plate 203 and the pressure plate 201 are strip-shaped plates, with multiple through-slots arranged in a row evenly spaced along their length. The material carrier 2 is constructed from multiple independent base plate 203-pressure plate 201 combination units, spliced ​​side by side. The rows of material support units 202 are arranged in a two-dimensional array.

[0028] In this embodiment, the material support unit 202 is a thin, one-piece thermoplastic formed using a vacuum forming process. Its wall thickness ranges from 0.3 to 1 mm, ensuring excellent processing and physical properties while significantly reducing the overall weight of the material carrier. Suitable thermoplastics include readily available materials such as polypropylene (PP), crystallized polyester (CPET), polyphenylene sulfide (PPS), and food-grade high-density polyethylene (HDPE). In this embodiment, the bottom of the material support unit 202 has a through-hole smaller than the outer dimensions of the supported material.
