Embodiment 1

[0024] A single-point needle valve hot runner system. The single-point needle valve hot runner system includes a cylinder block 3, a piston 4, a lower body 5, an upper body 2, a lower cylinder head 6, an upper cylinder head 1, and a nozzle body 7. Among them, by increasing the gap between the lower body 5 and the accommodating cavity; increasing the gap between the upper body 2 and the accommodating cavity, the upper body heater 2.5 is provided through the upper body 2, so that the upper body heater 2.5 can be opposed to the upper body 2 and The lower body 5 is heated.

[0025] The cylinder block 3, as a casing, plays a role of protecting and connecting the air source; the cylinder block 3 includes: an upper air inlet 3.3, a lower air inlet 3.4, a first guide belt 3.1 and a first sealing ring 3.2.

[0026] The upper air inlet 3.3 passes through the cylinder block 3, and a joint 3.5 is arranged outside the upper air inlet 3.3.

[0027] The lower air intake hole 3.4 penetrates the cyl...

Abstract

The embodiment of the invention provides a single-point needle valve hot runner system, and belongs to the technical field of hot runners. The single-point needle valve hot runner system comprises a cylinder, a piston arranged in the cylinder body, a lower body and an upper body, wherein a containing cavity is formed in the piston; the lower body is arranged in the containing cavity, and a first gap is reserved between the lower body and the inner wall of the containing cavity; the upper body is located above the lower body, the upper body is located in the containing cavity, and a second gapis reserved between the upper body and the inner wall of the containing cavity; an upper body heater is arranged on the outer side of the upper body, and the second gap communicates with the first gap; and the upper body heater sleeves the lower body through the second gap and the first gap. The technical effect that a single valve is smooth when injecting high-crystallization plastic or plastic with a relatively narrow forming temperature window is achieved.

Description

Technical field [0001] The invention relates to the technical field of hot runners, in particular to a single-point needle valve hot runner system. Background technique [0002] The single-point needle valve hot runner system (hereinafter referred to as "single valve") currently used in the industry is prone to blockage of the runner holes when injecting highly crystalline plastics or plastics with a narrow molding temperature window, and the injection molding cannot be completed. Resulting in increased after-sales maintenance, increased costs, and poor customer impressions. [0003] The current conventional treatment method is to appropriately increase the local or overall temperature of the nozzle to improve the plastic blockage. However, if the overall temperature of the nozzle is increased, when the temperature exceeds the normal molding temperature of the plastic, the characteristics of the plastic will change, which will cause other problems, and the side effects cannot be r...
