Abstract

The invention discloses a bulk molding compound (BMC) material forming die which comprises a fixed die and a movable die. Cooling inserts (15) are arranged around pouring sleeves (4) on the movable die. The invention further discloses a forming process of the forming die. By the adoption of the technical scheme, structural modification is conducted on a pouring system, a temperature control system, a forming system and an exhausting system, the forming temperature of the BMC material is effectively controlled, and injection molding of the BMC material is achieved; the forming production efficiency is improved; the product dimension is stable, the rejection rate is decreased, and the product quality is improved.

Description

technical field [0001] The invention belongs to the technical field of material forming and processing, and relates to a material forming mold structure. More specifically, the present invention relates to a BMC material molding die. In addition, the present invention also relates to the molding process of the molding die. Background technique [0002] BMC material is a kind of thermosetting material, which is mixed with various inert filler materials, multi-fiber reinforcement materials, catalysts, stabilizers and pigments to form a composite material for compression molding. The glass fiber of this material accounts for 10-30 %, the fiber length is generally 6-12mm; in special cases, in order to meet the mechanical properties, the fiber length should be 25mm. [0003] At present, more than 90% of the molding process of BMC materials adopts extrusion molding. The molding process of the prior art is time-consuming, laborious, low in production efficiency, high in scrap rat...
