Abstract
The utility model relates to the technical field of hot runner dies, in particular to a high-temperature hot sprue for a hot runner, which comprises a hot sprue body, wherein a sprue body part of the hot sprue body is sleeved with a sprue body sleeve; the sprue body sleeve is equipped with a heating device; a sprue bush is arranged at the bottom of the hot sprue body; a melted plastic runner is formed inside the hot sprue body; a sprue element is arranged at the bottom of the melted plastic runner; a spiral baffle is arranged on the sprue element; the outer side of the sprue element is sleeved with a sprue element sleeve; a spiral channel is formed in the sprue element sleeve by the sprue element; the spiral channel is communicated with the melted plastic runner. According to utility model, the structure of the sprue element is improved, so that dead angle effect is not generated when the melted plastic passes through the sprue bit, and the melted plastic can fully flow into the die cavity, and the product problem caused by the blockage of the sprue bit is avoided.
Description
Technical field
The utility model relates to the hot runner mould technical field, relates in particular to the high warm mouth of a kind of hot flow path.
Background technology
Hot runner hot mouth body is the hot mouth body of the present plastic material injection mo(u)lding of commonly using, hot mouth body with respect to cold runner structure, have economizing in raw materials, shorten the product molding cycle, reduce waste product, improve the quality of products, eliminate subsequent handling, help the advantage such as automated production.But, there is certain deficiency in design in its nozzle arrangements at present, following shortcoming is arranged: 1. melt plastic cement easily is stranded in sharp-tongued place, dead angle, each in moulding, the melt plastic cement at place, dead angle can not flow in die cavity, the melt plastic cement that rests on for a long time the place, dead angle can be decomposed or variable color, the Forming Quality of the next product of impact; 2. when the moulding high-temperature engineering plastics, the mouth section of meeting lip-syncing core produces wearing and tearing.
Summary of the invention
The purpose of this utility model is to provide a kind of hot flow path high warm mouth for the deficiencies in the prior art, the utility model is improved by the structure of lip-syncing core, do not produce dead angle effect while making the melt plastic cement process sharp-tongued, can flow into fully in die cavity, avoid occurring producing product quality problem because of sharp-tongued obstruction.
For achieving the above object, the high warm mouth of a kind of hot flow path of the present utility model, comprise hot mouth body, the mouth body of described hot mouth body is socketed with mouth body cover, described mouth body cover is provided with electro-heat equipment, the bottom of described hot mouth body is provided with sprue bush, the inside of described hot mouth body offers melt adhesive runner, the bottom of described melt adhesive runner is provided with the mouth core, described mouth core is provided with the spirality demarcation strip, the outer cover of described mouth core is connected to the mouth core retainer plate, and described mouth core forms a spirality channel in the inside of mouth core retainer plate, and described spirality channel is communicated with melt adhesive runner.
As preferably, the outer cover of described mouth core retainer plate is connected to heat conducting sleeve.
As preferably, described sprue bush and hot mouth body interference fit.
As preferably, described electro-heat equipment is copper sheathing formula heating circle.
As preferably, the top of described hot mouth body is provided with sealing ring.
The beneficial effects of the utility model: the mouth core is provided with the spirality demarcation strip, after the mouth core retainer plate enters in the mouth core retainer plate, the spirality demarcation strip is with the spatial separation spirality melt adhesive runner in the mouth core retainer plate, melt plastic cement enters die cavity along the spirality melt adhesive runner, avoided melt plastic cement to produce the dead angle phenomenon at the sharp-tongued place of mouth core, the utility model is improved by the structure of lip-syncing core, do not produce dead angle effect while making the melt plastic cement process sharp-tongued, can flow into fully in die cavity, avoid occurring producing product quality problem because of sharp-tongued obstruction.
