Embodiment Construction
[0025] Such as figure 1 , figure 2 , image 3 and Figure 4 As shown, the two-piece parison molding combination device of the present invention includes a die of the parison and a parison cutting device, the die includes a core 1, a tapered sleeve 2 and an outer cover 3, and the top of the core 1 is located in the tapered sleeve 2, The jacket 3 is located on the outer periphery of the mold core 1 and the taper sleeve 2, and the gap between the jacket 3, the mold core 1 and the taper sleeve 2 forms a parison runner 4, and the end of the parison runner 4 is a parison outlet 4a. Two groups of parison cutting modules are symmetrically arranged in the parison runner 4 with the axis of the mold core 1 as the center, and each group of parison cutting modules includes an upper separating block and a lower separating block, and the lower separating block is located directly below the upper separating block and There is a certain distance from the upper separation block, and the kni...

The invention relates to a two-piece parison forming method and a forming combined device thereof. The two-piece parison forming combined device consists of a die and a parison cutting device, wherein a pairson runner is formed by clearances among an outer cover of the die, a die core and a taper sleeve and is internally provided with two parison cutting modulessymmetrically, each parison cuttingmodule consists of an upper part separation block and a lower part separation block, the lower part separation block is positioned right under the upper part separation block, cuts of the upper part separation block and the lower part separation block both face upwards and are positioned in the same longitudinal cutting surface, the parts under the cuts of the upper part separation block and the lower part separation block are gradually widened. The parison cutting device consists of a base, a connecting seat and cutters, wherein the connecting seat is fixedly connected in the middle of the base, the upper end surface of the connecting seat is fixedly connected with the lower port of the die core, the cutters are symmetrically arranged at two sides of the upper part of the base and are respectively positioned right under the parison cutting modules, and the blades of the cutters upwards push against the die core and the outer cover, are both positioned on the longitudinal cutting surface and can smoothly cut a parison into two pieces.
Description
technical field [0001] The invention relates to a two-piece parison forming assembly device for an automobile fuel tank, and also relates to a two-piece parison forming method, which belongs to the technical field of parison forming equipment and processes for an automobile fuel tank. Background technique [0002] Automobile plastic fuel tank blow molding has been widely recognized by customers for its light weight, good safety performance, corrosion resistance, impact resistance, long service life and large design freedom. Due to increasingly stringent evaporative emission requirements, higher requirements are placed on fuel tank materials and structures. With the increasing awareness of environmental protection, relevant policies and regulations have put forward strict requirements for automobile OEMs. For example, California, the United States has issued PZEV (quasi-zero emission) regulations, which are for plastic fuel tanks produced by mainstream technologies. It is sa...
