Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of vacuum injection, specifically to a resin transfer molding vacuum injection equipment with accurate positioning. BACKGROUND

[0002] In the resin transfer molding (RTM) process, vacuum injection technology is widely used because it can effectively remove air and volatile substances from the mold, improving resin impregnation efficiency and product quality. However, the existing vacuum injection equipment still has deficiencies in accurate positioning, ease of operation, and production efficiency.

[0003] For example, a paper pulp molding injection molding mechanism (patent publication number CN218779248U) is proposed in Chinese patent. This device combines a vacuum pump and an injection device to achieve vacuum injection molding of resin materials. During use, the device can better control the injection pressure and speed of the resin, as well as the vacuum degree inside the mold, thereby improving the quality and consistency of the product to some extent. However, the above-mentioned patent only solves the basic control problem during resin injection and does not fully optimize the accurate positioning of the injection head, the quick opening and closing of the mold, and the overall automation level of the equipment.

[0004] The injection head in this patent lacks precise trajectory control during movement, which may result in uneven distribution of resin in the mold, affecting product performance. Additionally, the opening and closing operations of the mold are cumbersome and require manual intervention, reducing production efficiency. Therefore, we propose a resin transfer molding vacuum injection equipment with accurate positioning. UTILITY MODEL CONTENT
