Background

At present, the process of the expandable polystyrene foam plastic molding by mould pressing and foaming can be divided into two steps: filling a die cavity with cured pre-expanded polystyrene particles; in the second step, the particles are softened, the foaming agent in the foam holes is evaporated into gas, and the particles are further expanded due to the penetration of the heating medium, and the expanded particles fill all the cavity spaces and are fused into a whole due to the limitation of the volume of the cavity of the mold. After cooling and shaping, opening the mould and taking out the mould, thus obtaining the expandable polystyrene foam mould pressing foaming molding product.

However, when the particle material is fed and filled, the corner is often not filled completely, and a void is left, which is especially obvious when the corner or the mold with more details is formed. Although the subsequent foaming and expanding process can fill the hollow bubbles for forming, the density of the hollow bubbles is obviously lower than that of the filled part, so that the strength and the density of different parts of the finished foam part are not uniform, and the service performance of the finished product is influenced.

Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

As shown in fig. 1 to 6, an EPS foam molding mould, includes frame 1 and mould assembly, mould assembly includes mould 2 and lower mould 3, it connects to go up mould 2 and the sealed interlock of

lower mould

3, 3 both ends of lower mould all are equipped with

pivot

4, and 3 bottom surfaces of lower mould are equipped with vibrating

motor

8, 4 outer ends of pivot are rotated with frame 1 and are connected, frame 1 one side is equipped with rotating assembly, rotating assembly carries out axial rotation through pivot 4 control lower mould 3. High temperature resistant vibrating motor can be selected for use to vibrating motor 8, prevents to heat the inflation forming in-process and damages vibrating motor.
