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 discloses a rotary mold release injection mold, comprising a base, the top of the base is fixedly connected with a lower mold base, the top of the lower mold base is movably connected with an upper mold base, and the inner cavity of the lower mold base is movable The lower mold cavity is connected, and the upper mold cavity is opened at the bottom of the upper mold base, and the inner wall of the lower mold base is rollingly connected with balls, and the surface of the ball penetrates the inner wall of the lower mold base and extends to the inner cavity of the lower mold base , The invention relates to the technical field of injection molds. The rotation of the mold release injection mold starts the first drive motor, and the lower mold cavity is driven to rotate through the first drive shaft, so that it is separated from the upper mold cavity, and then the top block is driven to collide with the surface of the injection molded part. At this time, the first drive is started. The drive motor drives the lower mold cavity to rotate through the drive shaft. At this time, the injection molded part is fixed by the top block, so that the lower mold cavity and the injection molded part can be demoulded, and the injection molded part can be demoulded quickly, which is very convenient to use.
