Description
Technical Field
The utility model relates to a needle valve formula hot runner system technical field, concretely relates to needle valve formula hot runner is location structure for hot mouth.
Background
The hot runner is an advanced technology of a mature pouring runner system of the plastic injection mold, and is a hotspot direction of the development of a plastic injection molding process. Compared with the common runner mold, the hot runner mold has the advantages of high injection molding efficiency, good product quality, raw material saving and the like; the needle valve type hot runner is used as a more precise runner structure, so that the sprue mark of a product is more attractive, and the needle valve type hot runner is widely applied to various plastic products.
(see fig. 1 to 2) the conventional needle valve type hot nozzle includes a nozzle body 1, a valve needle 2, and a nozzle tip 3, but since the concentricity of the valve needle 2 is low during operation, the appearance of a customer product is reduced, and the wear of the valve needle 2 and the nozzle tip 3 is increased, resulting in a reduction in the service life of the valve needle 3.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a needle valve formula hot runner is location structure for hot mouth to the aforesaid of prior art not enough and defect to solve above-mentioned problem.
The utility model provides a technical problem can adopt following technical scheme to realize:
a positioning structure for a needle valve type hot runner hot nozzle comprises a nozzle body, a valve needle arranged in the center of the inside of the nozzle body and a nozzle head arranged at the bottom of the nozzle body and contacted with the valve needle, and is characterized in that a positioning part matched with the valve needle is arranged in the nozzle body.
In a preferred embodiment of the present invention, the positioning member is provided with a through hole adapted to the valve needle, and a plurality of waist-shaped holes are formed around the through hole.
In a preferred embodiment of the present invention, the diameter of the through hole is 5.05 mm, and the diameter of the valve needle is 5 mm.
In a preferred embodiment of the invention, the nozzle head is arranged in a conical or olive-shaped configuration.
In a preferred embodiment of the present invention, the positioning component is a valve needle positioning guide block.
Due to the adoption of the technical scheme, the beneficial effects of the utility model reside in that: the utility model discloses increase the locating part, the cooperation through locating part and needle can make the concentricity of needle during operation higher, improves the outward appearance of customer's product to can reduce the wearing and tearing of needle and nozzle head, through life.

Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further explained below.
Referring to fig. 3 to 5, the positioning structure for a needle valve type hot runner hot nozzle includes a nozzle body 10, a valve needle 20, and a nozzle head 30. The valve needle 20 is disposed at the inner center of the nozzle body 10, and the bottom of the nozzle body 10 is provided with a nozzle head 30 contacting the valve needle 10, the nozzle head 30 in this embodiment being disposed in a conical or olive-shaped structure.
The nozzle body 10 is provided inside with a positioning component 40 matched with the valve needle, the positioning component 40 is provided with a through hole 41 matched with the valve needle 20, the periphery of the through hole 41 is provided with a plurality of kidney-shaped holes 42, and each kidney-shaped hole 42 is connected with the through hole 41. The positioning member 40 in this embodiment is preferably a needle positioning guide block.
The diameter of the through hole 41 in this embodiment is 5.05 mm, and the diameter of the valve needle 20 is 5 mm, so that the concentricity of the valve needle 20 is improved when the valve needle 20 is operated by being engaged with the through hole 41 different by 0.05 mm when the valve needle 20 is inserted into the nozzle body 10.
The beneficial effects of the utility model reside in that: the utility model discloses increase the locating part, the cooperation through locating part and needle can make the concentricity of needle during operation higher, improves the outward appearance of customer's product to can reduce the wearing and tearing of needle and nozzle head, through life.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
