Definitions
- the present invention relates to a mold device for double-sided injection molding, that is, a mold device for stack molding, in which a center portion of each of a movable side and a fixed side of one side of the mold apparatus is arranged.
- a call that allows the extension nozzle for filling the molten resin to be fitted through and penetrates, and forms a fixed volume at the appropriate position of the runner gate part formed inside the manifold located at the center The present invention relates to a fixed-side partition resin leakage prevention mechanism in which a gate portion is formed and formed.
- a cylinder head In order to avoid stack molding of the general-purpose injection (model type), which is currently most frequently used in the molding industry, with the original model, gold is an absolute condition.
- a cylinder head In the center of the mold, a cylinder head is provided by an extension nozzle that passes through the center of the mold, including a part on one side of the injection cylinder, equipped with a face-to-face injection process. It must also communicate with the injection block. ”Thus, the molten resin is guided to the central injection block and injected into the cavity plates on both sides, but after cooling and hardening.
- the present invention relates to a double-sided injection molding mold apparatus having a space portion that can be previously expected on both sides of the axis of symmetry (the dimensions are the position of the product engraving part, the separation between the parts, the quantity, the resin material used, and the molding conditions). [Dimensions determined by factors such as temperature, pressing force, timing, alone:)...] are maintained and opposed to each other.
- the extension nozzle for supplying the molten resin from the injection cylinder for injection is penetrated and fitted, and the manifold is clamped in the above-mentioned listening interval, and the manifold is inserted.
- FIG. 1 is a cross-sectional front view of the preferred double-sided injection molding apparatus in which a part of the preferred double-sided injection molding apparatus is omitted, and FIGS. 2 to 4 show the preferred double-sided injection molding apparatus.
- Fig. 2 shows the mold in the closed state
- Fig. 3 shows the partially opened state
- Fig. 4 shows the product and runner falling in the fully opened state. is there.
- FIG. 1 is a cross-sectional front view in which a part of a preferred double-sided injection molding die apparatus (• M ⁇ A) according to the present invention is omitted, and both sides of the symmetry ⁇ (Y ⁇ ) are previously formed.
- the cold gate part is also formed according to the configuration, and during the double-sided injection molding work, the mold equipment for double-sided injection molding (S ⁇ M ⁇ A) Prevents the molten resin from becoming shallower than the fixed-side parting (P),...
- the structure is such that -m is the parting line of both cavity plates, (G) is the product, (R) is the runner, (D) indicates a drive pin, and (J * P) indicates an ejector plate.
- the mold apparatus according to the present invention has an excellent practical effect capable of solving the difficult conditions of the two major conflicts that the molding industry can currently attain: It promises an immeasurable contribution to improving the productivity of the molding industry.
