in the figure: 1. the device comprises a bottom plate, 2, a support, 3, an arc-shaped die, 4, a bearing seat, 5, a rotating shaft, 6, a connecting rod, 7, a fixing rod, 8, a steel wire, 9, a gear, 10, a telescopic mechanism, 11, a connecting shaft, 12, a rack, 13, a door-shaped frame, 14 and a guide pipe.
Detailed Description
The utility model is further described below with reference to specific embodiments, as shown in fig. 1: a mold for glass fiber reinforced plastic production comprises a horizontally arranged bottom plate 1, wherein a support 2 is arranged on the bottom plate 1, an arc mold 3 with an opening at the upper end and an axis extending along the front and back direction is arranged on the support 2, bearing seats 4 are respectively arranged on the bottom plate 1 on the front side and the back side of the arc mold 3, a rotating shaft 5 coaxial with the arc mold 3 is rotatably arranged in each bearing seat 4, a connecting rod 6 is arranged at one end, close to the arc mold 3, of each rotating shaft 5, a fixing rod 7 is detachably arranged between the two connecting rods 6, quick-connection flanges are arranged at two ends of each fixing rod 7, a steel wire 8 is arranged between the outer ends of the two connecting rods 6, a steel wire 8 tensioner is arranged between each steel wire 8 and each connecting rod 6, and the steel wire 8 tensioner is not repeated for the prior art; the steel wire 8 tensioner is beneficial to tensioning the steel wire 8;
a gear 9 is coaxially arranged on the outer side of one of the rotating shafts 5, a telescopic mechanism 10 is vertically arranged on the bottom plate 1, a connecting shaft 11 is coaxially arranged at the upper end of the telescopic mechanism 10, a rack 12 meshed with the gear 9 is vertically arranged at the upper end of the connecting shaft 11, the gear 9 and the rack 12 are herringbone teeth, meshing of the herringbone teeth is more stable, the telescopic mechanism 10 comprises a hydraulic telescopic rod, and the hydraulic telescopic rod is the prior art and is not described again; a door-shaped frame 13 is arranged on the outer side of the telescopic mechanism 10, a guide pipe 14 sleeved on the connecting shaft 11 is arranged on the door-shaped frame 13, the limit of meshing between the gear 9 and the rack 12 is realized through the cooperation of the guide pipe 14 and the connecting shaft 11, and a linear sliding bearing is arranged between the guide pipe 14 and the connecting shaft 11, so that the guide pipe 14 and the connecting shaft 11 can slide more smoothly; the vibration exciter is arranged on the outer side surface of the arc-shaped die 3, the vibration exciter is not repeated in the prior art, and the vibration exciter generates vibration, so that the adhesion between the glass fiber reinforced plastic finished product and the arc-shaped die 3 is loosened, and the demolding is easier;
thereby telescopic machanism 10 control rack 12 slides from top to bottom and has realized the rotation of gear 9, and the rotation of gear 9 realizes the synchronous rotation of two connecting rods 6, and steel wire 8 cuts into between arc mould 3 and the glass steel finished product, separates glass steel finished product and arc mould 3.
The specific working process is as follows: the operating personnel lays resin and glass fiber cloth according to established procedure inside arc mould 3 and waits for after the glass steel finished product is dry, start the vibration exciter, the vibration exciter produces the vibration, it is not hard up to make the bonding production between glass steel finished product and the arc mould 3, it is easier to make the drawing of patterns, thereby telescopic machanism 10 control rack 12 slides from top to bottom has realized the rotation of gear 9, the synchronous rotation of two connecting rods 6 is realized in the rotation of gear 9, steel wire 8 cuts into between arc mould 3 and the glass steel finished product, separate glass steel finished product and arc mould 3, the drawing of patterns is easier quick.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, many modifications and substitutions can be made without departing from the technical principle of the present invention, and these modifications and substitutions should also be regarded as the protection scope of the present invention.
