Abstract
The invention discloses an SMC material molding process, and relates to the technical field of plastic heat treatment. The process heats and pressurizes an SMC material by using a mold, so that the SMC material flows to fully fill in a cavity after being heated to reduce the viscosity, and products with excellent compactness are produced. The process is specifically suitable for processing large SMC products; and compared with a traditional hand pasting process, the SMC material molding process reduces the manpower, largely improves the production efficiency, largely improves the working condition, and prevents the human body harm from the glass steel material forming process.
Description
Technical field
The present invention relates to plastic hot processing technique field, specifically a kind of SMC material mould pressing process.
Background technology
At present, produce large glass product made from steel and how to paste fabrication technique by hand, when producing, typical products in mass production needs a large amount of moulds, manufacturing expense and the upkeep cost of mould are high, and take a large amount of production sites, production needs a large amount of hands to stick with paste skilled worker, production site takies larger, because of resin scent of, do not meet environmental requirement, workman's working condition is poor, and production efficiency is low, only after every product hand paste, the setting time on mould just reaches a few hours, and each mould output of a day is two to three products; Because of manual operation, became uneven is even again, and homogeneity of product is poor, and the rear surface of spraying paint easily produces bubble, has many unfavorable factors.
Summary of the invention
The deficiency that the present invention exists in order to overcome prior art, provides a kind of SMC material mould pressing process.
The present invention can be by taking following technical scheme to be achieved:
A kind of SMC material mould pressing process, its machining tool comprises forcing press and heating system, and described machining tool also comprises mould, in described mould, is provided with heating pipe line, and described mould is arranged on forcing press, and described mould pressing process is:
The packaging of a, releasing SMC material, the SMC material of clip suitable dimension, then weighs to it, and whether checking meets weight requirement;
B, unlatching heating system continue heat supply by water back to mould, and opening mold upper and lower mould is measured patrix temperature and whether met the temperature range of 155 DEG C+10 DEG C, measures counterdie temperature and whether meets the temperature range of 150 DEG C+10 DEG C;
C, clip SMC raw material are laid on counterdie;
D, startup press closes upper and lower mould are also exerted pressure, pressurize 3-10 minute;
E, unlatching upper and lower mould, the product of the thimble jack-up moulding of counterdie also maintains jack-up state;
F, taking-up product.
Optionally, described technique c also comprises: get and set the fiber of consumption or fabric and SMC material and be placed in altogether in die cavity.
Compared with prior art, the invention has the beneficial effects as follows: the product of SMC material be with mould heat, pressurizeing makes SMC material viscosity reduction, flows to make to be full of after mould and solidify, product adopts matched-mold forming dimensionally stable, product surfaces externally and internally smooth and beautiful appearance, can exempt to spray paint, physical and mechanical properties is all good, can realize production in enormous quantities, (comprising operations such as cutting out material, stone, compacting (pressure can reach 3000T more than), pressurize, jack-up, taking-up) is 8 minutes to add up the production time that certain product obtains every goods, day output can reach 170 or more than.
This technique simple to operate, do not need a large amount of professional hands to stick with paste skilled worker, remove hand from and stuck with paste the actual bodily harm of operation to skilled worker, professional and technical personnel is only by setting technological temperature, pressure, time etc., can technological parameter be carried out automatically and be controlled, realize batch production, reduced staff demand in a large number, reduced requirement to production site area, promoted production efficiency, and meet environmental requirement.

Detailed description of the invention
Below in conjunction with typical products accompanying drawing, most preferred embodiment of the present invention is described in detail.
As shown in Fig. 1 ~ 4, the machining tool of SMC material mould pressing process comprises forcing press and heating system, machining tool also comprises mould, in mould, be provided with heating pipe line, mould is arranged on forcing press, and the mold cavity surface of mould can be taked electroplating processes, the die cavity of mould is setting-in assembly, on die cavity and mould, be provided with match bindiny mechanism, can make to take to change die cavity and reach the object of producing different product under a similar design, SMC material mould pressing process is:
The packaging of a, releasing SMC material, the SMC material of clip suitable dimension, then weighs to it, and whether checking meets weight requirement.
B, unlatching heating system continue heat supply to mould, and as shown in Figure 1, opening mold patrix 1 and counterdie 2, measure patrix 1 temperature and whether meet the temperature range of 155 DEG C+10 DEG C, measures counterdie 2 temperature and whether meet the temperature range of 150 DEG C+10 DEG C.
C, the SMC material 3 of choosing is launched to cover on two preprepared bamboo poles, as shown in Figure 2, then carry bamboo pole being laid on counterdie 2 in SMC material 3 shift-in moulds by staff, the coloured glaze silk of getting setting consumption by technological requirement is layered on SMC raw material 3.
D, as shown in Figure 3, then close patrix 1 and counterdie 2 compress, and pressurize 6 minutes.
E, as shown in Figure 4, opens patrix 1 and counterdie 2, and the product 4 of the thimble 5 jack-up moulding of counterdie 2 also maintains jack-up state.
F, taking-up product 4.
Technological principle: this technology utilization the feature of duroplastic moulding materials heating and viscosity reducing, under the effect in conjunction with high pressure, make the full die cavity of mobile material automatic filling, produce the unified product of fine and close profile, have inborn advantage than manual production.
Only as described above, it is only the present invention's preferred embodiment, when not limiting with this scope of the invention process, the content of generally recording according to the claims in the present invention and description of the invention has been done simple equivalence and has been changed and modify, and is all still covered by the claims of the invention.In addition, summary part and title are only the use for auxiliary patent document search, are not used for limiting the present invention's interest field.
