Abstract
The invention discloses a nozzle core of a hot nozzle. The nozzle core of the hot nozzle comprises a square conical hole which is used for being combined with a hot nozzle main body flow channel, wherein the square conical hole is positioned at the bottom of the nozzle core of the hot nozzle; and the side length of the square conical hole is more than or equal to the diameter of the hot nozzle main body flow channel. The square conical hole is combined with the hot nozzle main body flow channel, so that the size of the nozzle core of the hot nozzle is easy to control during processing, a step is not generated at the combined position, and unqualified subsequent products caused by material accumulation are avoided.
Description
Technical field
The present invention relates to injection molding technology field, relate in particular to a kind of hot mouth mouth core.
Background technology
In common hot-fluid runner mold, mouth core retainer plate is connected in hot mouth main body, and mouth core end portion exposes outside hot mouth main body, and the melt plastic cement that is positioned at runner is extruded through overheated mouth main body and hot mouth mouth core, injects mold cavity, is shaped to product.In prior art, hot mouth mouth core joins by conical bore and the hot mouth main pipeline of bottom, because the difficult processing in hole is with controlling dimension, during polishing, easily become fillet, in the joint portion with hot mouth main body, form a step, this causes in production process and can, at step place accumulation plastics, cause follow-up product bad after plastics, yellow.
Summary of the invention
The technical problem to be solved in the present invention is how to solve the conical bore of existing hot mouth mouth core owing to being difficult to controlled working size, makes the joint portion of itself and hot mouth main body form step, causes the problem of buildup.
For solving the problems of the technologies described above, the invention provides a kind of hot mouth mouth core, comprise: for the square taper hole with the combination of hot mouth main body runner, described square taper hole is positioned at the bottom of described hot mouth mouth core, and the length of side of described square taper hole is more than or equal to the diameter of hot mouth main body runner.
Preferably, its material is steel.
This hot mouth mouth core adopts square taper hole to be combined with hot mouth main body runner, and its size work in-process is more easily controlled, and junction can not produce step, has avoided making subsequent product bad because of buildup.
Accompanying drawing explanation
Fig. 1 is the structural representation of hot mouth mouth core of the present invention.
Fig. 2 is the left view of the hot mouth mouth core in Fig. 1.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples are used for illustrating the present invention, but are not used for limiting the scope of the invention.
Hot mouth mouth core as shown in Figure 1 to Figure 2, its material is steel, comprising: for the square taper hole 2 of runner 4 combinations with hot mouth main body 1, square taper hole 2 is positioned at the bottom of hot mouth mouth core 3, and the length of side of square taper hole 2 equals the diameter of hot mouth main body runner 1.
This hot mouth mouth core adopts square taper hole to be combined with hot mouth main body runner, and its size work in-process is more easily controlled, and junction can not produce step, has avoided making subsequent product bad because of buildup.
Above embodiment is only for illustrating the present invention; and be not limitation of the present invention; the those of ordinary skill in relevant technologies field; without departing from the spirit and scope of the present invention; can also make a variety of changes and modification; therefore all technical schemes that are equal to also belong to category of the present invention, and scope of patent protection of the present invention should be defined by the claims.
Claims (2)
1. a hot mouth mouth core, is characterized in that, comprising: for the square taper hole with the combination of hot mouth main body runner, described square taper hole is positioned at the bottom of described hot mouth mouth core, and the length of side of described square taper hole equals the diameter of hot mouth main body runner.
2. hot mouth mouth core as claimed in claim 1, is characterized in that, its material is steel.
