Problems solved by technology
In the past, the development and design of auto parts usually used long-life metal molds, but not only the cost was high, but also the appearance and models of the current cars were updated rapidly, and the design and development of models were accompanied by the design and development of various structural and functional parts samples , and the development of each sample requires multiple adjustments to the mold, which not only leads to high development costs, but also greatly prolongs the development cycle
For this reason, also try to utilize resin mould, wooden mould, etc. in the prior art, but because existing wooden moulds adopt traditional runner heating system, not only manufacturing process is complicated, and control operation is complicated, and energy consumption is big, and wooden mold It is not heat-resistant, it adopts pipeline heating and cooling system, it is easy to cause mold deformation during work, the service life is very short, and the energy consumption is high

Embodiment 1
[0029] Such as figure 1 As shown, this embodiment provides a rapid prototyping system for auto parts samples, which mainly includes an injection module 10 , a molding module 20 and a control module 50 . The molding module 20 includes an injection molding machine and a wooden mold 30 provided in the injection molding machine. The wooden mold 30 includes an upper mold 31 and a lower mold 32, and when the upper mold 31 and the lower mold 32 are closed, a cavity 33 for injection molding can be formed. During injection molding, a reinforcing core material may be pre-set in the cavity 33 so as to form a sandwich reinforcing structure by injecting thermosetting resin. The injection molding machine is provided with a control mechanism for controlling the opening or locking of the wooden mold 30. For example, a control mechanism can be set under the lower mold 32 to control the closing (locking) or separation (opening) of the lower mold 32 and the upper mold 31. mold).

Abstract
The invention relates to a rapid prototyping process of auto parts samples, which belongs to the technical field of auto parts development. The rapid prototyping process of auto parts samples of the present invention adopts a wooden mold, and is provided with a heating mechanism of a heating cavity formed by an electric heating unit, the electric heating unit is composed of an electric heating rod filled in a heating groove on the upper mold, and There is no heating pipe in the mold. The temperature rise during the molding process is mainly concentrated in the cavity, which is conducive to improving product quality, and realizes the rapid development and verification of model part samples at low cost. Compared with the existing heating and cooling methods, it can save energy by about 80%.
Description
technical field [0001] The invention relates to the technical field of auto parts development, more specifically, the invention relates to a rapid prototyping process of auto parts samples. Background technique [0002] Energy saving and emission reduction is one of the main goals of the development of automobile technology. At present, new energy vehicles are the main technology development direction to achieve the goal of energy saving and emission reduction, and they are also the focus of governments. The popularization and application of energy vehicles is relatively slow. In this realistic situation, automobile lightweight is the most realistic choice for energy saving and emission reduction. Automobile lightweight is to reduce the quality of the automobile body as much as possible on the premise of ensuring the strength and safety performance of the automobile body, and at the same time to ensure the manufacturing of the automobile body. The cost is within reason. Ex...
