Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of quick sample part manufacturing, especially to an adsorption box sample part structure. BACKGROUND

[0002] Compared with the traditional mold manufacturing and production mode, the plastic quick sample part can be completed in a short time. This is very critical for the development and verification of new products, which can help enterprises quickly convert design concepts into physical objects and speed up the product development process to seize market opportunities.

[0003] Traditional plastic product production requires the production of molds, and the design, manufacturing and debugging of molds are costly, especially for complex-shaped products, the mold cost may account for a large proportion of the total cost. The quick sample part does not need to open an expensive mold in the small batch production or sample part stage, which greatly reduces the cost. In the early stage of product design, the design scheme may need to be continuously modified and improved. The plastic quick sample part can be easily modified, whether it is shape, size or structure, it can be quickly adjusted and re-produced, without the need for traditional mold production, once the mold is manufactured, modification becomes very difficult and expensive. With the help of advanced rapid prototyping technology, plastic sample parts with complex shapes and internal structures can be manufactured, which is very beneficial for some special product design, which can help designers better verify the feasibility and functionality of the design.

[0004] Although the size accuracy of the quick sample part is continuously improving, there is still a certain gap compared with traditional mold manufacturing. Especially for some products with very high size accuracy requirements, the quick sample part may not meet the requirements. There are differences in mechanical properties between the quick sample part and the mass-produced plastic product, which may affect the simulation and verification of the actual performance of the sample part on the product. In some products with high mechanical performance requirements, the test results of the quick sample part may not accurately reflect the actual performance of the product. The surface quality of the quick sample part is not as smooth and flat as the product produced by traditional mold production. In the rapid prototyping process, surface defects such as layer lines, bubbles and flaws may occur, which need to be treated and polished subsequently, increasing the production process and cost.

[0005] The existing adsorption box rapid sample is usually simple and fast in processing of non-woven fabric in the adsorption box during manufacturing, and only basic cutting and splicing operations are usually performed, and lacks fine and perfect processing as in actual mass production. For example, in the process of closely attaching the non-woven fabric to the main structure of the adsorption box or other components, the existing rapid sample may have the problems of poor close attachment and poor sealing, which will indirectly affect the actual air permeability and resistance of the non-woven fabric. Due to the above-mentioned process simplification, the performance of the non-woven fabric cannot be effectively improved and optimized, thereby causing a gap between the actual mass production product.

[0006] Therefore, there is an urgent need for an adsorption box sample structure which can accurately reflect the actual performance of the actual mass production product. Content of the utility model
