Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically a mold-driven integrated device for epoxy resin synthesis and casting. Background Technology

[0002] Epoxy resin, as a high-performance thermosetting polymer, is widely used in aerospace, automotive manufacturing, electronics, and building materials industries due to its excellent adhesion, corrosion resistance, mechanical strength, and electrical insulation properties. However, with the increasing demands for performance in epoxy resin products across various industries, more stringent challenges are being placed on the efficiency, stability, and precision of epoxy resin synthesis and casting processes.

[0003] In traditional epoxy resin production, the synthesis and casting stages are usually independent. Synthesis equipment mostly uses a sequential feeding and stirring method to mix raw materials, which suffers from poor mixing efficiency, leading to uneven mixing and affecting the quality and efficiency of epoxy resin synthesis. Furthermore, during the heating reaction, water vapor evaporation can easily entrain raw materials, resulting in waste, increased production costs, and potential environmental impacts. In the casting stage, traditional equipment often cannot efficiently integrate with the synthesis stage, leading to material losses during transfer, unstable temperature control, and difficulty in ensuring the flowability and curing properties of the epoxy resin during casting, easily resulting in defects such as bubbles, cracks, and uneven performance in the finished product. Moreover, the traditional separate operation of synthesis and casting requires large equipment footprints, has complex operating procedures, and low automation, making it difficult to meet the needs of modern large-scale industrial production. Therefore, developing a mold-driven integrated epoxy resin synthesis and casting device is of significant practical importance. This device integrates synthesis and casting functions, optimizes the stirring method to improve the mixing effect of raw materials, improves the heating and condensation recovery system to reduce raw material loss, and achieves seamless connection between the synthesis and casting processes. It also precisely controls process parameters such as temperature and pressure, improves production efficiency and product quality, reduces production costs and environmental burden, and promotes the development of epoxy resin production technology towards high efficiency, intelligence and greenness.

[0004] Chinese patent discloses a high-efficiency synthesis device for waterborne epoxy resin (authorization announcement number: CN201920856431.6). This device mainly includes a pretreatment unit body, a first valve, a servo motor, and a fixing assembly. The servo motor is connected to the motor output shaft via a limiting post, and its speed can be controlled according to the viscosity of the waterborne epoxy resin to adapt to different viscosity requirements. The inclusion of a pneumatic cylinder and a condenser pipe reduces losses during the raw material synthesis process. The raw materials are then mixed.

[0005] The process of obtaining waterborne epoxy resin after the reaction involves high temperatures, and the evaporation of water vapor during the feeding process can carry away raw materials, leading to waste in the synthesis of waterborne epoxy resin. However, this device still has certain limitations: it only optimizes the synthesis process and does not integrate the casting function. Although its structure optimizes the feeding process, the integrated hot pressing process of synthesis and casting still requires re-injection heating after discharging. In the future, combining it with a multi-functional mold with a heating module would make it more intelligent and practical.

[0006] Therefore, those skilled in the art have provided a mold-driven epoxy resin synthesis and casting integrated device to solve the problems mentioned in the background art. Utility Model Content

The device is compact, modular, and caters to both laboratory research and scale-up needs. It is applicable to multiple cutting-edge fields such as composite materials, functional coatings, and magnetically controlled smart materials, and has broad application value.
