Embodiment Construction

[0019] A specific embodiment of the present invention will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiment.

[0020] Please refer to Figure 2~4 , the hot runner system of the present invention includes a carrier plate 1, an upper code template 2, a support plate 3 before diversion, and a support plate 4 after diversion, and the support plate 3 before diversion is fixed on the front end of carrier plate 1 and upper code template 2, and after diversion The support plate 4 is fixed on the rear end of the carrier plate 1 and the upper code template 2, so that the carrier plate 1, the upper code template 2, the front support plate 3 and the diversion rear support plate 4 form a frame-shaped support seat.

[0021] Among them, such as figure 2 , 3 As shown, the frame-shaped support seat is provided with a diverter plate system, an ad...

Abstract

The invention discloses a hot runner system which includes a bearing board, an upper die arranging plate, a diversion front supporting board and a diversion back supporting board. A diversion board system can be adjusted through front-and-back accurate adjustment with a precision screw rod to regulate the distance between a hot nozzle of a fixed diversion board system and a hot nozzle of an adjustable diversion board system, so that the system is adaptable to products having different distances. Meanwhile, the length that a valve needle stretched out from the hot nozzle can be regulated through a position limiter, thereby enabling the system to be adaptable to products having different thickness. The hot runner system solves the defect that a hot runner system in the prior art can only produce products in single distance and single thickness. In addition, the hot runner system is strong in universality and is reduced in requirement on processing precision of the valve needles and such parts, so that the production cost is reduced.

Description

technical field [0001] The invention relates to injection molding equipment, in particular to a hot runner system. Background technique [0002] General injection molding equipment, such as: low-pressure injection molding machines, are usually equipped with a hot runner system. As a common part of the injection mold system, the hot runner system ensures that the plastic in the runner and gate remains molten by heating. [0003] Such as figure 1 As shown, the traditional hot runner system includes main structural accessories: hot nozzle (also known as hot nozzle) 101, bearing plate 102, positioning pin 103, manifold system 104, manifold support plate 105, piston 106, upper code template 107 , Cylinder head plate 108. Wherein, the cylinder block is directly processed on the upper code template 107, and the valve needle in the hot nozzle 101 is directly connected with the piston 106, and the maximum length that the valve needle stretches out is determined by the movement of ...
