Description

Technical Field

[0001] The utility model relates to the technical field of aluminum thermoforming molds, in particular to an aluminum thermoforming 3D printing mold insert. Background Art

[0002] The aluminum thermoforming mold contains water channels, and the insert is an important part of the mold. The traditional mold manufacturing process is machining after casting. This process has many disadvantages: 1. Machining can only produce straight water channels (such as Figure 1 As shown in the figure, the heat transfer surface on the mold has various shapes, which leads to large differences in the efficiency of heat transfer from the mold to different positions of the sheet, thus affecting product quality. 2. The water channel shape has great limitations and is prone to interference, which is not only difficult to design but also difficult to process.

[0003] Therefore, based on the above problems, how to provide an aluminum hot forming 3D printing mold insert has become an important technical problem that technical personnel in this field urgently need to solve. Utility Model Content

[0004] The purpose of the utility model is to overcome the defects of the existing technology and provide an aluminum hot-forming 3D printing mold insert in which the water channel shape is designed according to the mold surface shape, the heat transfer efficiency is more balanced, the weight is light, and the material utilization rate is high.

[0008] The working surface includes a first working surface and a second working surface;

[0009] The first working surface extends upward from one side of the insert body in a stepped and continuous manner and is connected to the second working surface. In the Y-axis direction, the first working surface extends from one end of the insert body to the other end in a wavy shape.

[0010] Water pipes are arranged in the insert body at intervals along the first working surface and the second working surface, and the water pipes extend from one end of the first working surface and the second working surface to the other end;

[0011] A plurality of weight-reducing grooves extending toward the working surface are formed at the bottom of the insert body, and the inner walls of the weight-reducing grooves located at the water pipe positions have protruding first avoidance portions.

[0012] Furthermore, the central axis of the water pipe is equidistant from the first working surface or the second working surface.

[0013] Furthermore, a first mounting hole and a second mounting hole are formed at the end of the insert body;

[0014] The first mounting hole extends from one end of the insert body to the other end;

[0015] The second mounting hole is a blind hole.

[0016] Furthermore, the weight-reducing grooves of the insert body corresponding to the positions of the first mounting hole and the second mounting hole are formed with raised second avoidance portions.

[0017] Furthermore, a plurality of third mounting holes are provided at the bottom of the insert body, and the plurality of third mounting holes are unevenly distributed. A protrusion is formed on the side wall of the weight-reducing groove for providing the third mounting holes.

[0018] Furthermore, a first through hole is formed at one end of the insert body, and a second through hole is formed at the other end; one end of the water pipe is communicated with the first through hole, and the other end is communicated with the second through hole.

[0019] In the above technical solution, the utility model provides an aluminum thermoforming 3D printing mold insert, which has the following beneficial effects:

[0020] Compared with the prior art, the aluminum thermoforming 3D printing mold insert designed in this utility model has an insert body and a water channel that is arc-shaped and arranged in accordance with the working surface of the insert body. The distance between the water channel and the working surface of the mold insert remains consistent with the degree of change in position. The heat transferred to the working surface of the mold insert by the water channel is more balanced, and the product quality is more stable.

[0021] Secondly, 3D printing mold inserts will not cause interference during the water pipeline design process, saving design costs;

[0022] In addition, when the mold insert is designed to reduce weight by opening a weight-reducing groove, an avoidance portion is set in the weight-reducing groove to avoid the installation holes of the water pipes and the insert body, which increases the space utilization rate, expands the overall weight reduction range of the insert, and increases the material utilization rate and reduces the weight.
