The invention discloses an automatic adjustable and detachable injection mold and relates to technical field of injection molds. The mold comprises a base, an outer shell body is fixedly connected tothe top of the base, and both sides of the bottom of the inner wall of the outer shell body are fixedly connected with support rods. A support plate is fixedly connected to the top ends of the supportrods, a lower shell body is movably connected to the top of the support plate, and an upper shell body is movably connected to the top of the lower shell body. Fixing blocks are fixedly connected toboth sides of the outer shell body, rotating rods are rotatably connected to the front surfaces of the fixing blocks, and one ends of the rotating rods penetrate through the outer shell body and extend into the outer shell body. According to the automatic adjustable and detachable injection mold and the working method thereof, simple and rapid disassembly of the injection mold can be achieved, sothat workers not only can conveniently remove objects in the injection mold, but also can conveniently clean the interior of the injection mold after the injection mold is disassembled to prevent theexcessive amount of waste inside the injection mold from affecting the normal injection molding work.

The invention discloses a rotary stripping type injection mold. The rotary stripping type injection mold comprises a base, wherein a lower mold seat is fixedly connected to the top of the base, an upper mold seat is movably connected to the top of the lower mold seat, a lower mold cavity is movably connected to an inner cavity of the lower mold seat, an upper mold cavity is formed in the bottom of the upper mold seat, a ball is in rolling connection to the inner wall of the lower mold seat, and the surface of the ball penetrates through the inner wall of the lower mold seat and extends to theinner cavity of the lower mold seat. The invention relates to the technical field of injection molds. According to the rotary stripping type injection mold, a first driving motor is started, and thelower mold cavity is driven to rotate through a first driving shaft, so that the lower mold cavity is separated from the upper mold cavity, then a top block is driven to be abutted against the surfaceof an injection molding part, the first driving motor is started at the moment, the lower mold cavity is driven to rotate through the driving shaft, and the injection molding part is fixed by the topblock at the moment, so that stripping is carried out between the lower mold cavity and the injection molding part so that the injection molding part can be quickly stripped, and the use is very convenient.

The invention relates to the field of steel molds, and in particular relates to a building steel formwork adapting to high vibration load. The building steel formwork adapting to high vibration load comprises a base, a first hinge shaft, a second hinge shaft and a third hinge shaft, wherein a turnover bracket is arranged on the left side of the top end of the base symmetrically front and back, theturnover bracket is hinged to the left end of a convex lower mold base through the first hinge shaft, an upper bracket is hinged to the right end of the convex lower mold base through the second hinge shaft, the bottom end of the upper bracket is fixedly connected with the output end of a hydraulic rod, a lower bracket is fixedly connected to a fixing end on the lower side of the hydraulic rod, arotating support is hinged to the lower bracket through the third hinge shaft, a lower sink groove is formed in the right side of the top end of the base, the bottom end of the rotating support is fixedly connected to the bottom end of the lower sink groove, a lower buffer groove is formed in the top end of the convex mold base, and four groups of first springs are symmetrically arranged at fourcorners of the bottom end of the lower buffer groove. The invention provides the building steel formwork which can adapt to high vibration load and can be rapidly cast to be formed.

The invention provides a conductive carbon / polymer based composite material comprising conductive carbon and a polymer, wherein the weight of the conductive carbon accounts for 1-45% of that of the polymer. The invention also provides a preparation method of the composite material. The preparation method comprises the following steps: (1) dispersing the conductive carbon in a solvent to obtain conductive carbon dispersion; (2) heating a solid polymer to obtain molten dispersion; (3) adding the conductive carbon dispersion into the molten dispersion, heating and stirring uniformly to remove the solvent so as to obtain a molten mixed material, wherein the weight of the conductive carbon accounts for 1-45% of that of the solid polymer, and the heating temperature is 0-10 DEG C higher than the melting temperature of the solid polymer; and (4) pouring the molten mixed material into a mold, cooling quickly for molding, and demolding to prepare the conductive carbon / polymer based composite material. By adopting the preparation method provided by the invention, the problems of the prior art are solved; and the preparation method is simple in process, relatively low in cost and suitable for industrial production.
