Embodiment Construction
[0021] Hereinafter, preferred embodiments of the present invention are given in conjunction with the drawings to illustrate the technical solutions of the present invention in detail.
[0022] figure 1 It is a schematic diagram of the overall structure of the present invention. figure 1 The molds required for foam processing and molding include upper mold 1 and lower mold 4. In the figure, mark 2 is the cut rough embryo of the foam size, and mark 3 is the finished product of foam molding.
[0023] Such as figure 1 Shown: The foam molding process provided by the present invention includes the following steps:
[0024] Step 1: Design of the forming mold: According to the different design of the final product structure, the sandwich foam shape that needs to be filled is designed, and then the corresponding foam forming mold is designed according to the foam shape. Finally, the foam molding mold is processed according to the mold design drawing;
[0025] Step 2: Selection of foam mater...

The invention relates to a foam mould-pressing forming technology. The foam mould-pressing forming technology comprises the following steps that 1, a foam material is selected; 2, the foam material iscut into the corresponding foam size according to the need; 3, the corresponding baking temperature is selected according to the foam of different materials; 4, the foam is baked, specifically, the foam with the cut size is put into a baking oven, and high-temperature baking is conducted according to baking parameters of the step 3, so that the essence of the foam reaches a creep state; and 5, the foam is subjected to mould-pressing for forming, specifically, the foam in the step 4 is put into a forming mould, then the mould is put on a hot press table, and the temperature and pressure parameters are set according to the standard of the foam mould-pressing forming technology for hot forming of the foam. Compared with a traditional finished foam product machined by a CNC milling machine, afinished foam product machined through the foam mould-pressing forming technology meets the requirement for the machining size precision as well, and the foam mould-pressing forming technology has the characteristics that the operation technology is simple, safety is good, size stability is high, the machining cost is low, the machining efficiency is high, and the surface appearance has no pollution such as burrs and chippings.
Description
Technical field [0001] The invention relates to a compression molding process, in particular to a foam compression molding process with good safety, high dimensional stability, low processing cost, and faster processing and molding efficiency. Background technique [0002] The traditional foam processing technology-CNC numerical control milling machine processing, the safety is not good, the dimensional stability is not high, the processing cost is high, the processing efficiency is not high, the surface appearance has burrs, chipping, and pollution, and the processing technology is not relatively uniform. Therefore, its scope of application is limited. Summary of the invention [0003] In view of the above problems, the main purpose of the present invention is to provide a foam compression molding process with good safety, high dimensional stability, low processing cost, and faster processing and molding efficiency. [0004] The present invention solves the above technical problem...
