Background technique

The construction of ships or vehicles and other means of transport often requires the first to make a one-to-one physical model. That is, the standard sample, or "main model", is used to re-form the mold of the sheet metal part. The progress and accuracy of a product development depends on the processing of standard entities and master models. Because of the standard entity, the main model reflects the total assembly relationship of the cover and the components one by one. It is the basis for manufacturing and reworking various molds and assembly fixtures, as well as the manufacture and coordination of sheet metal parts. People are interested in the research of standard entities and master models. In the standard entity, the existing processing technology of the main model, with epoxy resin as the binder, most of the processes are complicated, difficult to process, high in cost and long in production cycle. In particular, plastic processing using epoxy resin as a binder, due to the large proportion of minerals used as fillers, which causes the processing of plastic molds to have high strength, low toughness, high brittleness, and poor machining performance.

Step 2, the plastic sheet is covered with at least two layers of plastic film, and then at least two layers of kapok, shredded paper and flexible chain broken material are laid on the plastic film to form a mixed layer, and the mixed material is mixed. The top of the layer is covered with a plastic film;

Step 3: Put the bottom mold of the mold to be molded, adjust the height of the hydraulic device on the bracket of the mold boat according to the shape of the bottom of the bottom mold, and at the same time, cooperate with the steering limit device to establish a prototype of the bottom shape of the bottom of the ship, and the mold carrier bracket After adjusting the bottom contour and line of the bottom of the ship, take out the bottom mold of the mold to be molded; then, after applying the release agent to the insert and preheating, install the insert to the corresponding position of the mold ship bracket where the reserved hole needs to be set;

Step 4: Prepare epoxy resin compound:

First, the epoxy resin is placed in a batching tank for heating and melting, and when the epoxy resin reaches a predetermined temperature, the filler and the molten epoxy resin are uniformly stirred until a large amount of foam is generated, and then sent to the degassing tank. Degassing, then pouring into a vacuum vessel and thoroughly mixing, and adding an antifoaming agent to perform defoaming treatment; secondly, heating and melting the curing agent, and then thoroughly mixing the curing agent and the mixed epoxy resin to obtain The epoxy resin is mixed, and finally the deodorant is added to the epoxy resin mixture to prepare for the pouring work; the mass percentage of each component of the deodorant is: 16% to 33% of the extract of the leaves, and 6% of the turpentine. 9%/diatomaceous earth 8% to 17%, grapefruit peel extract 3% to 10%, propylene glycol 4% to 13%, inorganic salt 4% to 9%, sodium hyaluronate 3% to 7%, and the rest are water ;
