By through-hole；The ejector sleeve include from water gap plate to the sequentially connected fixed part in template direction and receiving portion, and have and institute
State the matched ejector sleeve inner cavity of hot mouth substructure；The ejector sleeve is fixed on by fixed part on water gap plate, and in the ejector sleeve
Chamber and through-hole docking；The first container, cold runner and the injection die cavities being sequentially communicated are equipped in the template；The template
After being molded with the water gap plate, the container accommodates the receiving portion of the ejector sleeve, the hot mouth lower part sequentially pass through through-hole and
It is connected to the cold runner behind ejector sleeve inner cavity, and former by the injection molding of cold runner to the injection molding intracavitary administration molten condition
Material.
Further, the hot mouth lower part tool is the pyramidal structure of reduced diameter.
Further, the water gap plate further includes the second container for accommodating the ejector sleeve fixed part, when installation, institute
Ejector sleeve fixed part is stated to accommodate and be fixed in second container.
Further, the template includes preceding mould and rear mold, and injection die cavities are formed after the preceding mould and rear mold molding, described
First container and cold runner are located on the preceding mould.
Further, the preceding mould includes front template and front cavity, after the preceding mould and rear mold mold, front cavity and rear mold
Between form injection die cavities, first container is located on the front template, and the cold runner is located in the front cavity.
The injection mold of the utility model extends the length of hot mouth, shortens the length of cold runner, so as to save
Injection raw material；By in injection mold be arranged can the ejector sleeve of partial receipt in a template, to hot mouth play positioning and protection make
With avoiding hot mouth and deformed because long；In addition, when being molded to water gap plate and template, ejector sleeve can be towards die sinking direction
Hot mouth is ejected from template.

Fig. 2 is the elevational cross-sectional view of dispensing mould in the middle part of the utility model first embodiment.
Fig. 3 is the structural schematic diagram of mould before part in the utility model second embodiment.
Specific implementation mode
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Mode, the present invention will be further described in detail.
It should be noted that in this specification, the direction for defining hot mouth injection injection raw material is to inject from top to bottom.
With reference to figure 1, Fig. 2, the utility model first embodiment provides a kind of injection mold for saving water material, including from upper
Hot mouth 1, water gap plate 2, ejector sleeve 3 and the template 4 set gradually under；The hot mouth is for melting and injecting injection raw material；It is described
Water gap plate be equipped with allow the hot mouth lower part by through-hole 21；The ejector sleeve 3 includes sequentially connected fixation from top to bottom
Portion 31 and receiving portion 32, and with the matched ejector sleeve inner cavity of 1 substructure of the hot mouth 33；The ejector sleeve 3 passes through fixation
Portion 31 is fixed on the water gap plate 2, and the ejector sleeve inner cavity 33 is docked with the through-hole 21；It is equipped with successively in the template 4
The first container 41, cold runner 42 and the injection die cavities 43 of connection；After the template 4 is molded with the water gap plate 1, container 41
Receiving portion 32 for accommodating the ejector sleeve 3,1 lower part of the hot mouth sequentially pass through behind through-hole 21 and ejector sleeve inner cavity 33 with it is described cold
Runner 42 is connected to, and injects the injection raw material of molten condition into the injection die cavities 43 by cold runner 42.
In the present embodiment, is formed after the injection raw material cooling and solidifying in injection die cavities 43 and wait for injecting products 5, in cold runner 42
Injection raw material cooling and solidifying after formed regrinding-material 6.This implementation extends the length of hot mouth compared with conventional techniques, will
Hot mouth, which is inserted into, can effectively shorten the length of cold runner in template, so as to save injection raw material；By in injection mold
Middle setting can the ejector sleeve of partial receipt in a template, positioning and protective effect are played to hot mouth, hot mouth is avoided and becomes because long
