Description

Technical Field

[0001] The utility model relates to the field of automobile parts manufacturing, in particular to a production device for a polyurethane buffer block. Background Art

[0002] The traditional polyurethane buffer block production equipment technology has significant efficiency and economic challenges in the manufacturing process, limiting its application potential in modern industrial production. The typical polyurethane buffer block production equipment is designed for single-station operation, and each pouring can only inject raw materials into one cavity of the mold to form a single product. Although this traditional model may be sufficient in the early production environment, its inherent limitations have become particularly obvious as market demand continues to grow and competition becomes increasingly fierce.

[0003] The main problem is the low utilization rate of equipment. Since only one product can be produced in each molding process, even if the mold design and process control are optimized, the full-load operation time of the production equipment is greatly limited, resulting in insufficient output per unit time and unable to effectively meet the needs of large-scale production. The limitation of production capacity directly affects the market competitiveness of enterprises. In today's global market environment, high efficiency and low cost are key factors for the survival and development of enterprises. The production equipment of traditional polyurethane buffer blocks has limited single-shot molding output. In order to maintain a certain production rate, it is often necessary to start and stop the equipment frequently, which consumes a lot of energy. At the same time, the preheating and cooling cycle of the mold is long, which further increases energy consumption, which does not meet the current general requirements for green production and energy conservation and emission reduction.

[0004] Therefore, seeking new polyurethane buffer block production equipment technology that can improve equipment utilization, increase production capacity, reduce energy consumption and improve market competitiveness has become a key issue that the industry needs to solve urgently.
