Described mould when the cloth material is carried out pressurized, heated, about 200 ℃ of needed heating-up temperature, and about 10 seconds of pressurized, heated time each time; In other words, it was 10 seconds that each group mould rests on the minimum time of carrying out moulding on the cloth material, then one minute can only six parts of moulding, each hour can only moulding 360, if the needed time when adding meter cloth material and being transferred, then fertile number of spare parts definitely is less than 360 each hour; Again, if when the temperature of aforementioned heating is lower, in order to obtain identical molding effect, just then upper and lower mould needed to prolong to time of cloth material pressurization, production efficiency thus just can descend.In order not destroy the character of cloth material, common aforesaid heating-up temperature should not be too high, also because so, the manufacture method that is exclusively used in loudspeaker cloth-made part traditionally can't promote production efficiency for a long time.
As shown in Figure 3, because traditional mould must be at the inner heater C (for example electric heater) that installs of the B of patrix A and counterdie, to such an extent as to desire is not easy when heater is maintained; For example, during desire maintenance heater, mould just needs to shut down simultaneously can't operation, so just can influence the carrying out of entire job.
Summary of the invention
Main purpose of the present invention is to solve the shortcoming on traditionally the manufacture method that is exclusively used in loudspeaker cloth-made part, i.e. needed overlong time of cloth workpieces of its moulding is to such an extent as to can't promote production efficiency.
A further object of the present invention is the other shortcoming of the manufacture method that is exclusively used in loudspeaker cloth-made part that solves traditionally, be that it utilizes mould to the pressurized, heated moulding simultaneously of cloth material, because its heater is mounted in the mould, is not easy to such an extent as to desire is maintained heater.
Major technique feature of the present invention, be to contain the cloth material that is soaked with resin to carry out earlier carrying out moulding again after the preheating, simultaneously preheating and operations for forming are arranged in same production line in regular turn, use making that adding hot work does not influence the carrying out of operations for forming and promoted production efficiency.
Another technical characterictic of the present invention, be that heater and mould branch are arranged, therefore, when needs are maintained heater, as long as the heater that will maintain is pulled down, the heater that another group has been finished maintenance is installed on original production line and just can continues to produce again, and comparing with traditional manufacture method has excellent progressive.
A technical characterictic more of the present invention, be that last processing procedure at mould is provided with apparatus for leveling, allow the cloth material by behind the heater, earlier by apparatus for leveling with the arrangement of cloth material smooth after, give moulding by described mould again, so that the surface of finished product is more attractive in appearance.
Based on this, method of moulding provided by the present invention, be will be in advance through containing resin pickup and the cloth material crossed of dried with intermittence move mode in regular turn by a heater and a molding tool, and apparatus for leveling such as rolling rumble can be according to need be set between heater and mould, by this heater to the preheating of cloth material, and utilize apparatus for leveling with cloth material arrangement smooth after, under room temperature environment, the cloth material forming of preheating is gone out part shape by this mould again, at last the part after the moulding is cut to obtain finished product, promoted production efficiency by this flow process of working continuously.
