Embodiment Construction

[0023] combine figure 1 and Examples illustrate the present invention in detail.

[0024] Integral hot runner without runner dead angle includes: valve needle (1), fixing screw (2), diverter plate (3), lever body (4), sliding piece (5), hydraulic cylinder (6) and hot nozzle (7 ).

[0025] The front end of the hot nozzle (7) is provided with a valve needle (1) for opening and closing the nozzle.

[0026] The lever body (4) and the diverter plate (3) are connected and fixed with fixing screws (2).

[0027] The lever body (4) and sliding piece (5) are assembled together after being connected with the vertical shaft, the horizontal shaft and the middle shaft.

[0028] The lever body (4) is the main supporting object for the action of the sliding piece (5), and one end of the lever is connected to the hydraulic cylinder (6) through screws.

[0029] One end of the lever is connected to the hydraulic cylinder (6) by screws, and the other end is fixed on the splitter plate (3). T...

Abstract

An integral hot runner without runner dead angle, including: valve needle, fixing screw, diverter plate, lever body, sliding piece, hydraulic cylinder and hot nozzle, characterized in that: the front end of the hot nozzle is provided with opening and closing When the valve needle of the nozzle is opened, the plastic enters the mold cavity through the manifold and the hot nozzle in turn; the lever body and the manifold are connected and fixed with fixing screws. After the hot runner is assembled, the manifold and the hot nozzle runner are docked in place and connected without gaps to form a whole. The hot runner can be hoisted as a whole when the mold is assembled, and there is no seepage, leakage, and decomposition of the stock during the injection molding production process. It can effectively improve the production efficiency of injection molding, improve the appearance of injection molding products, and improve the quality of plastic parts.

Description

technical field [0001] The invention relates to a hot runner device, in particular to an integral hot runner without a dead angle of the runner. Background technique [0002] The hot runner mold is a new structure that heats the runners and runners of the traditional two-plate mold or three-plate mold frequently, and does not need to take out the runners and runners during each injection molding cycle. The hot runner system generally consists of several parts such as hot nozzles, manifolds, temperature control boxes and accessories. Hot nozzles generally include two types: open hot nozzles and needle valve hot nozzles. Since the form of the hot nozzle directly determines the selection of the hot runner system and the manufacture of the mold, the hot runner system is often divided into an open hot runner system and a needle valve hot runner system. [0003] Diverter plate is used when one mold has multiple cavities or multi-point feeding, single-point feeding but the materi...
