Abstract
The utility model discloses a kind of hot runner hot mouth with glue sealing structure, offer the mouth body of passage in comprising and be installed in the hot mouth of mouth body one end, described hot mouth center is provided with the needle be connected with mouth body internal channel, it is characterized in that: also comprise heat conduction shuttle and heat insulation cap, described heat conduction shuttle is placed on outside needle, described heat insulation cap is placed on outside heat conduction shuttle, and heat conduction shuttle head and heat insulation cap head adopt side seal plastic structure.The hot runner hot mouth with glue sealing structure described in the utility model, can prevent heat insulation cap pressure from collapsing, and effectively solves the product colour mixture problem that heat insulation cap pressure is collapsed produced.
Description
Technical field
The utility model relates to hot runner mould technical field, particularly relates to a kind of hot runner hot mouth with glue sealing structure.
Background technology
Along with the development of injection molding technology, Hot runner Technology applies in injection mold more widely.Hot mouth is the vitals in TOP-TIP.In prior art, hot runner hot mouth as shown in Figure 1, offer the mouth body 10 of passage in hot mouth 1 comprises and be installed in the hot mouth 11 of mouth body one end, hot mouth 11 center is provided with the needle 110 be connected with mouth body 10 internal channel, outside needle 110, cover has heat conduction shuttle 111, and outside heat conduction shuttle 111, cover has heat insulation cap 112.In prior art, heat conduction shuttle 111 complete closure is lived by heat insulation cap 112, due to hot mouth in use, temperature is high, and thermal expansion phenomenon can occur for hot mouth, heat conduction shuttle, and when hot flow path is stopped using, hot mouth can be lowered the temperature again contraction; In the process of frequent rising-heat contracting-cold, heat insulation cap will be caused to be collapsed by pressure and produce gap (as shown in Figure 2 and Figure 3, wherein pressure collapses position as shown in 2 in Fig. 3, the gap of collapsing easily is pressed) after producing thermal expansion, in production, the plastic cement of melting just clamp-ons gap, the plastic cement entering gap is caused plastic cement to degrade, burn jaundice because being detained by heating for a long time, enters product colour mixture.
Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide one can prevent heat insulation cap pressure from collapsing, and effectively solves the hot runner hot mouth with glue sealing structure of the product colour mixture problem that heat insulation cap pressure is collapsed produced.
For achieving the above object, the technical scheme that the utility model proposes is: a kind of hot runner hot mouth with glue sealing structure, offer the mouth body of passage in comprising and be installed in the hot mouth of mouth body one end, described hot mouth center is provided with the needle be connected with mouth body internal channel, it is characterized in that: also comprise heat conduction shuttle and heat insulation cap, described heat conduction shuttle is placed on outside needle, and described heat insulation cap is placed on outside heat conduction shuttle, and heat conduction shuttle head and heat insulation cap head adopt side seal plastic structure.
Adopt technique scheme, the hot runner hot mouth with glue sealing structure described in the utility model, can prevent heat insulation cap pressure from collapsing, and effectively solves the product colour mixture problem that heat insulation cap pressure is collapsed produced.

Fig. 2 is that the hot runner hot mouth of prior art caves in schematic diagram;
Fig. 3 is the A portion enlarged diagram of Fig. 2;
Fig. 4 is structure of hot sprue of hot runner schematic diagram described in the utility model;
Fig. 5 is the B portion enlarged diagram of Fig. 4.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As illustrated in figures 4-5, the hot runner hot mouth with glue sealing structure described in the utility model, wherein hot mouth 1 is offered the mouth body 10 of passage and is installed in the hot mouth 11 of mouth body one end in comprising, hot mouth 11 center is provided with the needle 110 be connected with mouth body 10 internal channel, outside needle 110, cover has heat conduction shuttle 111, and heat insulation cap 112 is placed on heat conduction shuttle 111 side; And heat conduction shuttle head and heat insulation cap head adopt side seal plastic structure, heat conduction shuttle 111 head outer diameter engages sealing glue position 1110 with heat insulation cap 112 head endoporus and fits tightly; During concrete use, hot mouth 11 entirety is located in mould 3.
In this way, in use, the sealing of heat conduction shuttle head and heat insulation cap head is fit sealing in side to hot mouth, and the thermal expansion direction that hot mouth produces be axis, therefore the phenomenon that heat insulation cap pressure collapses by heat conduction shuttle can not be produced, thus effectively solve the product colour mixture problem that heat insulation cap pressure collapses produced.
Although specifically show in conjunction with preferred embodiment and describe the utility model; but those skilled in the art should be understood that; not departing from the spirit and scope of the present utility model that appended claims limits; in the form and details the utility model is made a variety of changes, be protection domain of the present utility model.
