The die cavity for matching, it is semicircular cavity A that then the two ends Milling Process in die cavity goes out cross section, finally in the bottom of die cavity
Two variable cross-section strip grooves are processed, so as to produce mold；
S3, lower mould is made, first take a pressing mold B, then gone out and leaf spring following table facial contour in the upper surface Milling Process of pressing mold B
The boss for matching, then the two ends Milling Process cross section of boss be semicircular cavity B, so as to produce lower mould；
Material is loaded in S4, mold and lower mould and core is installed, filled up by resin, profound into the top of boss and cavity B
The mixing material of military rock fiber and fiber cloth composition；Fill up by resin, the Black Warrior into die cavity, cavity A and variable cross-section strip groove
The mixing material of rock fiber and fiber cloth composition；Mold is fastened on into lower die top, it is ensured that cavity A is matched with cavity B
Form one and complete open circles, core is inserted in open circles, realize and load material and installation in mold and lower mould
Core；
The compression molding of S5, basalt fibre flat spring, applies basipetal pressure to mold, material is mutually extruded,
After a period of time is processed, you can compression molding goes out basalt fibre flat spring, forms plate wherein between die cavity and boss
Spring, forms grasswort between cavity A, core, cavity B, at variable cross-section strip groove forms basalt fibre muscle.
The present invention has advantages below：Manufacturing process of the present invention is simple, reduce production cost, rigidity and intensity are high, prolong
Long leaf spring service life.

Specific embodiment
The present invention will be further described below in conjunction with the accompanying drawings, and protection scope of the present invention is not limited to described below：
As shown in Fig. 1 ~ 5, a kind of preparation method of basalt fibre flat spring, it comprises the following steps：
S1, the threedimensional model for setting up leaf spring according to the requirement of required leaf spring；
S2, mold is made, first take a pressing mold A, then gone out and 1 upper surface of leaf spring wheel in the lower surface Milling Process of pressing mold A
The die cavity 2 that exterior feature matches, it is semicircular cavity A3 that then the two ends Milling Process in die cavity 2 goes out cross section, finally in die cavity 2
Bottom process two variable cross-section strip grooves 6, so as to produce mold；
S3, lower mould is made, first take a pressing mold B, then gone out and 1 lower surface wheel of leaf spring in the upper surface Milling Process of pressing mold B
The boss 4 that exterior feature matches, then the two ends Milling Process cross section of boss 4 be semicircular cavity B5, so as to produce down
Mould；
Load material in S4, mold and lower mould and core be installed, fill up into the top of boss 4 and cavity B5 by resin,
The mixing material of basalt fibre and fiber cloth composition；Fill up into die cavity 2, cavity A3 and variable cross-section strip groove 6 by resin,
The mixing material of basalt fibre and fiber cloth composition；Mold is fastened on into lower die top, it is ensured that cavity A3 and cavity B5
Match and to form one and complete open circles, core 7 is inserted in open circles, realize and load material in mold and lower mould
With installation core；
The compression molding of S5, basalt fibre flat spring, applies basipetal pressure to mold, material is mutually extruded,
After a period of time is processed, you can compression molding goes out basalt fibre flat spring, formed wherein between die cavity 2 and boss 4
Leaf spring 1, forms grasswort 8 between cavity A3, core 7, cavity B5, at variable cross-section strip groove 6 forms basalt fibre muscle
9；As shown in Figure 4 and Figure 5, basalt fibre muscle 9 is arranged along the length direction of leaf spring 1, and as basalt fibre muscle 9 has pole
