Background
In a hot runner system, temperature detection of a splitter plate is an important link, and thus strict requirements are imposed on the quality and fixation of a temperature sensing line. The structure and the fixing mode of various plate-type temperature sensing lines in the current market are different, so that the distribution of the heating pipes of the splitter plate and the design of the shape of the splitter plate have to be changed in consideration of the defects of the structure and the fixing mode of a hot runner system in use; and the temperature sensing line is easy to loosen, temperature deviation is easy to cause, and hidden danger is increased for forming.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a hot runner temperature sensing line fixing device.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a hot runner temperature sensing line fixing device, it includes the flow distribution plate, fixed collet chuck and tight screw, it has temperature sensing line hole and tight screw hole to open on the flow distribution plate, fixed collet chuck is opened along the central axis has the first hole that supplies the temperature sensing line to pass, fixed collet chuck is along vertically evenly opening flutedly, form collapsible structure between the adjacent recess, the material of fixed collet chuck is the spring steel, tight screw is opened along the central axis has the second hole that closely cooperates with the appearance of fixed collet chuck, the screw thread section of tight screw and the tight screw hole cooperation of flow distribution plate.
Furthermore, both ends of the first inner hole of the fixed collet adopt fillet transition.
Furthermore, the shape of the fixed collet chuck consists of a cylinder shape and a horn shape, and good positioning and matching effects are achieved.
Has the advantages that:
1. the utility model discloses effectively changed the fixed mode of temperature sensing line, the heating tube of being convenient for arrange and the design of flow distribution plate appearance, can effectively avoid the defect of arranging position and flow distribution plate design of heating tube.
2. The utility model discloses a fixed collet chuck and holding screw have effectively ensured that the temperature sensing line is not hard up, stabilize the temperature sensing line on the flow distribution plate, make it temperature sensing respond well to effectual accurate measurement accuracy of having guaranteed.
3. The utility model has the advantages of simple structure, simple to operate guarantees not to cause product defect because of the temperature sensing line of flow distribution plate loses the temperature.
