Abstract: A high-pressure composite container is provided. At least a plastic-liner is provided with a plastic shell and a metal end encapsulated by the plastic shell. The plastic-liner of the sealing structure only consists of the plastic shell and the metal end, and the sealing structure is simple. The metal end and a bottle mouth valve jointly compress a sealing ring on the bottle mouth valve, so that the sealing ring forms a stable compression amount, and finally the high-pressure gas cylinder has excellent sealing performance. In addition, the metal end and the plastic shell are well positioned both axially and circumferentially. In the case of high and low pressure and temperature alternation, the relative positions of the metal end and the plastic shell do not change, and a sealing surface of the plastic shell does not deform and dislocate.

Abstract: The hollow body molding aid includes a body, a connector, a first profiling assembly, a second profiling assembly, and a positioning mechanism. The connector is fixedly connected to the body. The first profiling assembly is fixedly disposed on one side of the body and is configured to position one half of a reinforced housing. The second profiling assembly is fixedly disposed on the other side of the body and is configured to position the other half of the reinforced housing. The positioning mechanism is disposed on the first profiling assembly and the second profiling assembly. The reinforced housing can be positioned, thus guaranteeing molding quality of the reinforced housing and blanks. In addition, the reinforced housing can be accurately positioned in a cavity of a mold through a manipulator, without the need to use a plurality of air cylinders for step-by-step driving.

Abstract: A hollow body forming mold includes left and right half molds, a bottom of the left half mold is provided with a left avoidance slot, a bottom of the right half mold is provided with a right avoidance slot, a left bottom slider is disposed in the left avoidance slot, a right bottom slider is disposed in the right avoidance slot, and the left and right bottom sliders constitute a group of sliders. The mold design resolves a difficult problem that a fabrication hole exists during forming of a hollow body with a built-in component by using an existing conventional process. The hollow body forming method has the advantages of a short forming period, the high production efficiency, good combination between a built-in component and an inner wall of an fuel tank, and the high location stability.

Abstract: A method for molding a two-piece blow molded hollow tank by using auxiliary male molds includes the following steps: 1) blanking two parisons; 2) closing mold halves of a mold and a pre-molding template; 3) pre-stretching the molten parisons by using auxiliary male molds in the pre-molding template; 4) performing internal high-pressure blow molding, and pre-molding two housing portions; 5) opening the mold, and withdrawing the pre-molding template; 6) moving in a component built-in mechanism to perform built-in component connection; 7) moving out the component built-in mechanism; 8) closing the mold for the second time and finally blow molding a hollow tank; and 9) opening the mold and taking out the product.

Abstract: A molding method of blow-molding a hollow tank body with a built-in component is provided. The method molds the hollow tank body by molding the sheet parisons in the half molds. After the moving cooperation of the half molds, an expanding mechanism of a pre-molding template device, the template half plates and the bases, the half molds are respectively leaned against the closed template half plates, and the sheet parisons are leaned against the half molds by blowing and/or sucking so as to be pre-molded. The tank body is molded after placing the component into it. A pre-molding template device is also provided. An expanding mechanism and the template half plates are mounted on the bases, and the bases are mounted on a rail bracket, the bases are driven by a power device to move on the rail bracket.
