Embodiment Construction

[0027] According to the claims of the present invention and the content disclosed in the summary of the invention, the technical solution of the present invention is specifically as follows:

[0028] In the prior art, the processing size of the single-point needle valve has been fixed and fixed, and it cannot be adjusted, which is prone to error problems. The previous single-point needle valve had to undergo mold repair or modify the valve needle before completing the operation, and it required multiple data changes to complete the operation. Meet reasonable requirements.

[0029] The utility model discloses a single-point needle valve to solve the above problems.

[0030] figure 1 It is a schematic diagram of the structure of the single-point needle valve of the present invention, please refer to figure 1 , a single-point needle valve, including:

[0031] figure 2 It is a structural schematic diagram of the cylinder body of the single-point needle valve of the present in...

Abstract

The invention discloses a single-point needle valve. The single-point needle valve solves the problem that based on the prior art, a single-point needle valve processing size has already been determined and positioned and cannot be adjusted so that errors are produced easily and before operation is finished, the existing single-point needle valve is subjected to multiple mold modification or valve needle modification processes until the existing single-point needle valve data satisfies reasonable requirements. The single-point needle valve avoids multiple modification processes through utilization of a limit screw, realizes one-step adjustment of the cooperation of a valve needle and a mold to the optimal state, reduces mold and hot runner system modification time and optimizes product appearance quality.

Description

technical field [0001] The invention relates to a needle valve, in particular to a single-point needle valve. Background technique [0002] The needle valve is a sealing valve, which is used to close the continuous flow of plastic in the molten state. Once the product is filled, the needle valve needle will be closed according to the signal source of the injection molding machine, so as to achieve the function of valve closure. [0003] The traditional single-point needle valve hot runner system is processed according to the original design drawings, and the processed dimensions have been fixed and positioned. If there is a dimensional error in the hot runner system or the mold hole processing, it must not be achieved. The original design requirements and the required sealing effect will affect the product quality appearance and quality requirements. Contents of the invention [0004] The invention discloses a single-point needle valve, which is used to solve the problems...
