Embodiment Construction

[0026] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments, but the scope of implementation of the present invention is not limited thereto.

[0027] like Figure 1 to Figure 4 As shown, a double self-locking stroke continuously adjustable high-precision micro-spacing foaming mold described in this embodiment includes a bottom plate 1, two spacers 2 arranged side by side on the bottom plate 1, and an opener with self-locking function. Distance from drive mechanism 3, lower die base 4, sliding plate 5, lower die core 6, upper die base 7 and upper die core 8;

[0028] The distance drive mechanism 3 is arranged on the bottom plate 1 and is located between the two cushion blocks 2, and the output end of the distance drive mechanism 3 is connected with a lifting plate 9;

[0029] The lower die base 4 is fixed on the two spacers 2 and is located above the lifting plate 9, and the lower die base 4 is pr...

Abstract

The invention discloses a double-self-locking stroke continuously adjustable type high-precision micro-opening-distance foaming mold which comprises a bottom plate, a cushion block, an opening distance drive mechanism with a self-locking function, a lower mold base, a slide plate, a lower mold core, an upper mold base and an upper mold core, wherein the opening distance drive mechanism is arrangedon the bottom plate, and the output end of the opening distance drive mechanism is connected to a lifting plate; the lower mold base is arranged on the cushion block and provided with a mold guide column; the slide plate is correspondingly matched with a slide rod through a slide guide sleeve to be sleeved with the lower mold base in a sliding mode, one end of the slide rod is fixed to the slideplate, and the other end of the slide rod penetrates through the lower mold base and then is fixedly connected to a lifting plate; the lower mold core is fixed on the slide plate; the upper mold baseis correspondingly connected to the mold guide columns in a sliding and sleeved mode through the mold guide sleeve; the upper mold core is arranged in the upper mold base; and the lower mold base, thelower mold core, the upper mold base and the upper mold core are assembled to form a mold cavity; According to the invention, the lower mold core is ensured not to shift under injection molding pressure, and the defects of a low or overlarge foaming rate and out-of-tolerance product thickness are avoided.

Description

technical field [0001] The invention relates to the technical field of mold injection molding, in particular to a double self-locking stroke continuously adjustable high-precision micro-spacing foaming mold. Background technique [0002] Injection molding is a plastic molding method in which molten plastic is injected into the cavity of a molding mold for cooling and molding. [0003] In the existing injection molding process, the volume of the mold cavity is fixed, and the products obtained by injection molding are high-density plastics. In order to reduce the density of the injection molded products and achieve the purpose of saving materials, a micro-spacing foam injection molding process has been developed. In the process of injection molding, the plastic particles are mixed with the foaming agent particles and then injected into the mold cavity by the injection molding machine. During the high temperature melting process of the plastic, the foaming agent particles decom...
