The invention relates to a method for detecting an optical photograph of a large mold casting blank. The method is characterized in that a lug boss and a peripheral unfinished surface formed by a workpiece are subjected to bulge application; all processing molding surfaces are subjected to data acquisition; a system is established for acquired 3D points, and is compared with the prior theory three-dimensional design data; finally, a digital control processing alignment standard report is released. Under a report chart environment, each direction required in digital control processing is standardized, generally, display of the standard is required to be determined by trial cutting on a machine tool, and theoretical coordinate values, offset directions and dimensions of the coordinates are displayed to be used for digital control processing alignment and standard determination. The method accurately determines the digital control processing standard, reduces load of the machine tool and time for aligning the center by digital control equipment, and accelerates cycle of cast output. A digital control programming staff can reasonably program a digital control processing program through allowance deviation data, thereby improving effective operation time of the digital control machine tool, reducing consumption of cost, improving working efficiency of digital control processing while ensuring the quality of digital control processing, and accelerating the output cycle of cast blank.

The invention discloses a composite heat retainer and a preparation method. The composite heat retainer comprises a silicon carbide-based composite ceramic base body and phase-change materials. The silicon carbide-based composite ceramic base body is in a regular geometrical shape and provided with holes. The phase-change materials are charged in parts of the holes. The two ends of each hole filled with the phase-change materials are subjected to hot melting sealing through sealing bodies. The holes which are not filled with the phase-change materials are heat conducting holes which are of communication structures. The preparation method comprises the steps of silicon carbide-based composite ceramic base body preparing, sealing body preparing, phase-change material charging and the like. The composite heat retainer can enable the quantity of the phase-change materials contained by the silicon carbide-based composite ceramic base body to be easy to control; and in the heat storage process, sensible heat storage of the silicon carbide-based composite ceramic base body and latent heat storage of the phase-change materials are organically combined, so that the purposes of improving the heat storage efficiency and optimizing the heat storage process are achieved. The preparation method is capable of simplifying the manufacturing process, reducing the manufacturing cost and accelerating the manufacturing period.

The invention provides a method for manufacturing a serialized sofa, comprising the following steps of: a, establishing a standard part library, wherein the standard parts library comprises part identification numbers and first corresponding relations between the part identification numbers and sofa types, wherein the part identification numbers are used for indicating standardized parts; b, determining a sofa type to be manufactured; c, determining the part identification number according to the sofa type and the first corresponding relation; and d, assembling the standardized parts indicated by the part identification numbers into a sofa. In the invention, parts in reserve can be directly looked up from a standardized part database through establishing the standardized part database after the sofa is designed, and thereby the making period of the sofa from design to a finished product is shortened; meanwhile, because the standardized parts are adopted, the part inventory can be reduced and the cost is further reduced.

The invention discloses a zinc alloy die-casting die ejection mechanism. The zinc alloy die-casting die ejection mechanism comprises a fixed die plate, a moving die plate, a moving die safety bar, a push plate push block, a guide block, a limiting pin and a plug pin, wherein a fixed core is installed on the fixed die plate, a moving core is installed on the moving die plate, a push plate guide post is fixedly installed on the moving die safety bar, a first push plate, a first ejector plate, a second push plate, and a second ejector plate are sequentially arranged on the push plate guide post, the first push plate penetrates through the push plate guide post, the first ejector plate is fixed on the first push plate, the second ejector plate is fixed on the second push plate, and the first push plate, the first ejector plate, the second push plate and the second ejector plate can slide up and down along the push plate guide post. By means of the zinc alloy die-casting die ejection mechanism, the phenomena that the clasp force is large, products are failed to be taken out of the die, die-casting is poor, and spray does not reach the designed position in the product die-casting process, and ejector rods and inserts are broken and pulled crack in the production process are effectively improved.

The invention relates to the technical field of heat accumulators, in particular to a novel efficient composite heat accumulator and a preparation method thereof. The novel efficient composite heat accumulator comprises a silicon carbide multiphase ceramic matrix, holes are formed in the silicon carbide multiphase ceramic matrix, part of the holes are filled with phase change materials, the two ends of the holes filled with the phase change materials are sealed through hole packaging pieces in a hot melting mode, and the phase change materials are filled with the phase change materials. And the holes which are not filled with the phase change material form heat conduction holes which penetrate through the silicon carbide-based multiphase ceramic matrix structure. According to the novel efficient composite heat accumulator, sensible heat accumulation of the silicon carbide composite ceramic matrix and latent heat accumulation of the phase-change material are organically combined, the purposes of improving the heat accumulation efficiency and optimizing the heat accumulation process are achieved, and compared with an existing sodium chloride silicon carbide heat accumulator, on one hand, the filling amount of the phase-change material can be increased; on the other hand, the manufacturing process can be simplified, the manufacturing cost can be reduced, and the manufacturing period can be shortened.

The invention provides a hub color over-coating method which comprises the steps that (S1) a shaping face of a hub is sprayed and coated with a first color paint; (s2) the shaping face is sprayed andcoated with a second color paint which covers the first color paint; (s3) baking treatment is carried out; and (s4) the shaping face comprises a removal area, the second color paint on the removal area is removed, and the first color paint is exposed. The solution has the beneficial effects that development of a spraying protection tool is omitted; cost is saved; a manufacture cycle is increased;a border line at a border of two colors is distinct; the method is particularly applicable to color over-coating processing of a special car type which has a plane capable of finish turning; and the solution not only can realize color over-coating of an edge plane of the hub, but can also realize color over-coating of a spoke. The invention also provides a manufacture method for the hub.
