Abstract
The invention provides a manufacturing method of an acoustic mold, which comprises the following steps: providing a die cavity of the acoustic mold and liquid epoxy resin; filling the epoxy resin into the die cavity; and cooling. The manufacturing method of the acoustic mold provided by the invention has the advantages of low cost and high molding speed.
Description
[technical field]
The present invention relates to the Resins, epoxy Application Areas, relate in particular to a kind of method of making acoustic mold of Resins, epoxy.
[background technology]
Epoxy resin embedding adhesive is that epoxy curing agent mixes the composition epoxy resin that obtains with Resins, epoxy and additive.At present, Chang Yong amine epoxy resin solidifying agent has fatty amine and the solidifying agent of modification and the aromatic amine solidifying agent of hot setting of intermediate temperature setting.
The fatty amine of intermediate temperature setting and the solidifying agent of modification thereof, normal temperature for liquid, easily mixes with Resins, epoxy down, and processing performance is good.
The aromatic amine solidifying agent is because of all containing the phenyl ring of Heat stability is good, so its thermotolerance, chemical proofing, electromechanical properties that solidifies the gained composition epoxy resin is better than using the intermediate temperature setting agent in its molecular structure.But, being generally solid under the aromatic amine normal temperature of this class, fusing point is higher, is that 91-93 ℃, diaminodiphenylsulfone(DDS) fusing point are 178-179 ℃ as the diaminodiphenylmethane fusing point.As the necessary first heat fused of solidifying agent, could mix with Resins, epoxy down at 90 ℃ then, obtain the joint sealant that can be used for pouring into a mould.
In the correlation technique, the method for making acoustic mold mainly comprises: the die cavity that removes to pour into acoustic mold with the plastic pellet under the molten state.In this method, the cooling time of plastics is longer, in case and acoustic mold need to revise, the change repeatedly of mold needs higher cost and speed obviously to slow down.
[summary of the invention]
The technical problem that the present invention need solve provides a kind of method of making acoustic mold fast of Resins, epoxy.
For solving the problems of the technologies described above, the invention provides a kind of method of making acoustic mold, this method may further comprise the steps:
Provide the die cavity of described acoustic mold, the Resins, epoxy of liquid state;
Pour into described die cavity with described Resins, epoxy;
Cooling.
Beneficial effect of the present invention is: be liquid before Resins, epoxy is uncured, have suitable intensity and hardness after the curing; Liquid Resins, epoxy is similar with the plastic pellet under the molten state, state after the curing is similar with the characteristic of cooling back plastics, utilize this characteristic, use the rapid shaping of Resins, epoxy to make the injection moulding frock of the alternative short run of acoustic mold and the early development that is applied to product, advantages such as it is low to have cost, and speed is fast.
[description of drawings]
Fig. 1 is one embodiment of the invention acoustic mold die cavity synoptic diagram.
[embodiment]
The invention will be further described below in conjunction with drawings and embodiments.
The invention provides a kind of method of making acoustic mold, this method may further comprise the steps:
Provide the die cavity 1 of described acoustic mold, the Resins, epoxy of liquid state;
Pour into described die cavity with described Resins, epoxy;
Cooling.
Be illustrated in figure 1 as one embodiment of the invention acoustic mold die cavity synoptic diagram, practical Resins, epoxy injects die cavity 1, and is promptly plastic after the curing.
For the research and development of new product, the Resins, epoxy acoustic mold of practical this method rapid shaping product need not die sinking, just can finish the affirmation of product at client performance, rapidly and efficiently, more can effectively avoid the change repeatedly of mold simultaneously.
Above-described only is embodiments of the present invention, should be pointed out that for the person of ordinary skill of the art at this, under the prerequisite that does not break away from the invention design, can also make improvement, but these all belongs to protection scope of the present invention.
Claims (1)
1. the making method of an acoustic mold, it is characterized in that: this method may further comprise the steps:
Provide the die cavity of described acoustic mold, the Resins, epoxy of liquid state;
Pour into described die cavity with described Resins, epoxy;
Cooling.
