Problems solved by technology

[0002] At this stage, the reflector glass used in our photothermal power generation field is about 4mm, and the glass is connected to the bracket by pasting ceramic sheets with bolts. The strength of this structure depends entirely on the quality of the glass. Therefore, the photothermal power generation mirror Some life expectancy will be affected
In addition, the reflectivity of this kind of mirror is only about 93%, which affects the efficiency of photothermal power generation

Embodiment 1

[0028] The SMC liner 6 of the present invention includes an arc-shaped upper surface plate, a peripheral edge 61 integrally molded on the back of the upper surface plate, and a plurality of criss-cross rims integrally molded in the peripheral edge. Plate-shaped reinforcing ribs 62 are integrally molded with nuts 3 at the intersections of some of the reinforcing ribs, and cylindrical reinforcing holes 63 are formed at the intersections of the rest of the reinforcing ribs.

[0029] The SMC liner of the present invention adopts the cavity structure formed by the upper surface plate and the surrounding ring, which meets the overall strength design requirements, and a plurality of criss-crossing plate-shaped reinforcing ribs are arranged inside the surrounding ring to improve The load-bearing strength of the upper surface plate is improved, and reinforcing holes or nuts are set at the intersection of the reinforcing ribs, which can effectively meet the subsequent assembly requiremen...

Embodiment 2

[0033] The molding die for preparing the SMC liner of the present invention includes an upper template 71 and a lower template 72,

[0034] The upper template includes a upper template 711 and an upper ejector plate 712 located above the upper template. The upper template is provided with a plurality of through air holes 713. The upper template is provided with a plurality of The upper blocking rod 714 used to seal the air hole, the air hole is controllably communicated with the compressed air source through the air channel 715;

[0035] The lower template includes a lower template 721 and a lower ejector plate 722 arranged below the lower template. The lower template is provided with a plurality of thimble holes, and the lower ejector plate is provided with a The ejector rod 723 corresponding to the thimble hole.

[0036] Specifically, the SMC liner is formed by a hydraulic press. The working pressure of the hydraulic press is 2000T, and the pressure is maintained for 2-4 mi...

Embodiment 3

[0041] Further, in order to prevent the SMC material in the molten state from flowing into the cavity of the nut during molding, a nut positioning cavity for accommodating the nut 3 is provided on the lower mold plate, and a nut positioning cavity for accommodating the nut 3 is provided on the upper molded bar. The corresponding pressure rod perforation of the top ring, the nut pressure pin 716 that can match through the pressure rod perforation and be pressed on the top ring is arranged on the upper thimble plate, such as the nut pressure pin 716 There are four needles. Four nut pressing pins are used to press the nut and the lower plate tightly to reduce the generation of gaps, which can effectively prevent the entry of SMC and avoid the inconvenience of subsequent installation. Of course, the nut pressing pins can also be directly arranged on the upper mold plate.

[0042] Preferably, it also includes a SMC liner board retrieving mechanism, which includes a frame and a dri...

Abstract

The invention discloses an SMC lining plate and a forming die thereof. The SMC lining plate comprises an arc-shaped upper surface plate, a peripheral ring edge integrally formed on the back portion ofthe upper surface plate in a compression molding mode and a plurality of criss-crossed plate-shaped reinforcing ribs arranged in the peripheral ring edge in an integral compression molding mode. Nutsare integrally formed at the intersections of part of the reinforcing ribs in a die casting mode, and cylindrical reinforcing holes are formed at the intersections of the other reinforcing ribs. According to the SMC lining plate disclosed in the invention, a cavity type structure composed of the upper surface plate and the peripheral ring edge is adopted, the overall strength design requirement is met, the criss-crossed plate-shaped reinforcing ribs are arranged in the peripheral ring edge, the bearing strength of the upper surface plate is improved, the reinforcing holes or nuts are arrangedat the intersections of the reinforcing ribs, the subsequent assembly requirement can be effectively met, and rapid positioning and installation are achieved.

Description

technical field [0001] The invention belongs to the technical field of production and preparation of silver mirrors, and in particular relates to an SMC liner and a molding die. Background technique [0002] At this stage, the mirror glass used in our photothermal power generation field is about 4mm, and the glass is connected to the bracket by pasting ceramic sheets with bolts. The strength of this structure depends entirely on the quality of the glass. Therefore, the photothermal power generation mirror Some life expectancy will be affected. In addition, the reflectivity of this kind of mirror is only about 93%, which affects the efficiency of photothermal power generation. [0003] The applicant proposes a technology of using SMC material hot-press forming as the reflector back plate, which is a kind of SMC composite material and glass fiber reinforced plastic. The main raw materials are composed of GF (special yarn), MD (filler) and various auxiliary agents. SMC compo...
