Embodiment Construction

[0012] The technical scheme of the present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

[0013] Such as figure 1 As shown, the needle-valve hot runner 3 is placed on the base with the hot-fluid plate 1 on top and the hot nozzle 5 facing down. 2. The hot runner 3 and the hot nozzle 5, wherein the heater 4 is arranged on the hot runner 3. figure 1 The bottom of the needle valve hot runner 3 is the base, including a bottom plate 6 with a certain thickness, because there may be multiple hot runners 3 and hot nozzles 5 on one hot runner plate 1, so there are corresponding numbers of nozzles on the bottom plate 6 The groove 7, for the case of multiple grooves 7, the position of the groove 7 and the position of the hot nozzle 5 need to be i...

Abstract

The invention discloses a base of a needle valve type hot runner. The base is characterized by comprising a bottom plate with certain thickness, wherein a plurality of grooves are formed in the bottom plate; at least two guide columns are arranged at the periphery of the bottom plate; an uncovered collecting barrel is arranged in each groove; a heater is arranged on the side wall of each collecting barrel; a circular top tray is arranged on the top of each guide column; the length of each guide column is greater than the distance between a hot nozzle and a hot runner plate by over 20mm. The needle valve type hot runner can be conveniently placed in a mode that the hot runner plate is upward and the hot nozzle is downward, molten plastic remained in the hot runner can conveniently flow out of equipment, the hot nozzle can be quickly dried, and the molten plastic can be conveniently removed.

Description

technical field [0001] The invention relates to a base of a needle valve type hot runner. Background technique [0002] A hot runner is a collection of heating components used in injection molds to inject molten plastic into the cavity of the mold. Among them, the needle valve hot runner saves material, the surface of the plastic part is beautiful, and the internal quality is tight and the strength is high. [0003] The existing design of the needle valve hot runner is inverted after use, that is, the hot nozzle is placed upwards and the heat flow plate is placed below. This will cause the melted plastic remaining in the hot runner to flow into the heat flow plate and cannot be discharged, which is inconvenient Cleaning also affects the service life of the equipment. Contents of the invention [0004] In view of the above problems, the present invention provides a needle valve hot runner base, which is convenient for placing the needle valve hot runner with the hot flow ...
