It can effectively reduce batch batch batch.The cost of a single transfer during production.

The invention discloses a manufacturing method for improving an integral golf club head, which includes the following steps: (1) precasting an internal sleeve, the outer contour of which is the same with the shape of an inner cavity of the golf club head, and at least one opening is arranged in the internal sleeve; (2) preparing granular filling materials for the internal sleeve and placing the filling materials into the inner cavity of the internal sleeve through the opening; (3) precasting a die-casting die of the club head; (4) fixing the entity of the internal sleeve in the die-casting die; (5) casting metal liquid, the casting melting point of which is not higher than the melting point of the metal material of the internal sleeve, into the die, and the die is cast and formed; (6) preparing a club head embryo which consists of a shell layer, an internal sleeve layer and filling materials after die de-molding; (7) drilling a bore hole which permeates the shell layer and the internal sleeve layer on the embryo club head; and (8) manufacturing the golf club head by arranging the opening of the bore hole downward to cause the filling materials to flow out automatically from the bore hole. The method also discloses a product made by adopting the method.

The invention discloses a repulsive clamping static contact structure of low-voltage circuit breaker. The two ends of a locating shaft are fixed on a support, the middle of the locating shaft penetrates a static contact and pressure springs which are respectively arranged at the two sides of the static contact, the pressure spring is enveloped in the support and causes a connector row to compact the static contact, the free end of the static contact is arranged in a through slot on the bottom wall of the support, a tension spring is arranged in a first through slot of the support and corner approach thereof is fixed on a first boss in the first through slot, and the other corner approach of the tension spring penetrates the other through slot on the bottom wall of the support and is fixedly connected with the free end of the static contact. The static contact structure of the invention is modularized, clamping structure is adopted to realize electrical connection between static contact and inlet wire row, contact resistance is less, service life of static contact of circuit breaker can be prolonged, assembly is simple, and production cost is low.

The invention relates to a split type small-sized manned lunar surface lander sealed cabin. The split type small-sized manned lunar surface lander sealed cabin comprises a docking mechanism, a passage, a main cabin body and a side scuttle, wherein the docking mechanism, the passage and the main cabin body are connected with each other in sequence; the side scuttle is supported on the main cabin body; the side scuttle comprises a first side scuttle part and a second side scuttle part; the first side scuttle part can be opened in a direction far away from the second side scuttle part; and the second side scuttle part can be opened in a direction far away from the first side scuttle part. According to the split type small-sized manned lunar surface lander sealed cabin, as the side scuttle comprises the first side scuttle part and the second side scuttle part which can oppositely opened, the side scuttle can also be used as a sealed cabin door; and therefore, the floor space of the sealedcabin door in the prior art is saved, the structure of the sealed cabin is made more compact and the light of the sealed cabin is made much lighter.
