Exchange O... K. The practical effects of this invention are outstanding, and it is an excellent invention that can definitely improve productivity regardless of the type of molding company. The basic structure of a stack mold for a general-purpose injection mold (horizontal type) is, first, a pair of cavity plates with parting on both sides, and a cavity in the center that allows injection of molten resin into the cavities on both sides. However, as a constraint on this basic structure, when moving to the mold opening process after the injection process, molten resin may leak or leak onto both cavity parting lines. In addition, the occurrence of nasal dripping, stringiness, etc. is not acceptable in the slightest. This is because the occurrence of such an event means that the resin that caused the product or molten resin leakage, dripping, etc., gets caught on the parting line during mold clamping in the next process. This is because there is a risk of serious accidents involving the molded product or the mold itself. This further
Today, in the molding industry, we are in an era where unmanned operations are common day and night in order to improve productivity, and a high degree of rationalization of productivity is required. It is also said that it is almost impossible to dare to adopt it. The present invention was developed in view of these points, and focuses on the point where the extension nozzle and the central injection block, which have been connected until now, are separated when the mold of a double-sided injection block is opened. Considering that it is natural for the molten resin to leak from the part of the lid, the present invention is designed to make the extension nozzle itself expandable and retractable by having a double pipe structure and slidingly fitting the extension nozzle itself. That's enough points. The following description will be made based on the embodiments shown in the drawings. Symmetry axis Y- of double-sided injection molding machine SMA
On the Y, manifolds M and H occupying an appropriate capacity [width b x height h x thickness t] are respectively attached to a pair of movable side M.
The molten resin M from the injection cylinder of the molding machine (not shown) is placed in the center C-C of one side of the double-sided injection molding device SMA , which is made up of CP and fixed side FCP cavity plates arranged and sandwiched. In order to inject and fill the cavity plate, the tubular core I can be slid freely inside the outer cylinder P, in which the cylindrical heater H is fitted in the outer layer. Exercise possible]
The extension nozzle N is inserted through the extension nozzle N, and S and S in the figure are spacers, and L is a spacer.
-l, l-l are parting lines, G, G,...
denotes the product, R, R, ... denotes the liner, D, D, drive pin, F the mounting plate, and JP the ejector plate. Since the present invention is constructed as described in detail, during the mold opening process after the injection process, for example, the tubular core I of the extension nozzle N is attached to the movable cavity plate.
It slid together with the MCP and the mounting plate F, and there was no phenomenon of molten resin leaking during the mold opening process. The contribution it has made to the molding industry is immeasurable.
