METHOD FOR FORMING TWO-PIECE BLOWED HOLLOW BOX BODY WITH AUXILIARY MALE DIE
The present invention relates to a method for forming a two-piece blowed hollow box body with an auxiliary male die, comprising the following steps: 1) cropping a two-piece parison; 2) closing a half mould of a die and a preforming template; 3) an auxiliary male die on the preforming template prestretching a fusing parison; 4) performing internal high-pressure blowing, and preforming a two-piece shell; opening the die so that the preforming template exits; 6) moving in an assembly building-in mechanism to connect the built-in assemblies; 7) moving out the assembly building-in mechanism; 8) closing the die for the second time and finally forming the hollow box body by blowing; and 9) opening the die to take out the product. In the present invention, during preforming by closing a half mould of a die and a preforming template, by using an auxiliary male die, the parison is stretched to a large range in an auxiliary manner; therefore, a plastic fuel tank with a high extension ratio and uniform wall thickness is formed and manufactured, so that the shape of the fuel tank can be highly freely designed, thereby ensuring better product forming quality.
A two-sheet parison extrusion planar opening mold device includes a core rod (1), a mold core (6), a mold sleeve (3), shearing devices (4), a flow divider (5), and a connecting device (2). A first-stage parison passageway (7) is formed between the outer side of the connecting device (2) and the inner side of the mold sleeve (3). The shearing devices are arranged at the upper portion of the branching device symmetrically. The bottom of the flow divider is configured as a hollow cavity structure. The core rod drives the vertical movement within the cavity of the mold core, the gap between the mold core and the mold sleeve being adjusted by means of this movement. The overall structure of the device is simple and the existing axial wall thickness control system can continue to be used without reconfiguration of equipment. A molding method using the planar mold device is disclosed.
Disclosed are an automobile urea tank and a forming method thereof. The forming method comprises the following steps: firstly, producing an upper half casing and a lower half casing (2, 1) by means of injection moulding; assembling built-in components of the upper and lower half casings (2, 1) after the upper and lower half casings (2, 1) are formed; integrally welding the assembled upper and lower half casings (2, 1); and assembling components and parts on the surfaces of the upper and lower half casings (2, 1). The method improves the degree of freedom in the design of the built-in assemblies of a tank body, saves raw materials, has a simple structure and good firmness, improves production efficiency, and shortens the production period.
