Description
Technical field
The utility model relates to pin shell injection mold field, in particular to a kind of no mouth of a river pin molds.
Background technique
Pin shell as shown in Figure 1, existing most of pin shell injection molds use the small click-through glue in the thin mouth of a river of cold runner,
The mouth of a river is long, and waste of material is more.Or more existing factory uses needle valve type hot runner into glue, the heat distribution of hot nozzle is not easy to control, and heat
Nozzle head space is small, and the head that heating wire can not reach hot mouth causes the head Re Zui to be easy cold glue, so that the blocking of the head Re Zui is residual
Glue misfires glue, and product is easy jaundice and not can effectively solve, and can not normally produce.
Utility model content
The purpose of the utility model is to provide one kind can guarantee that hot nozzle runner internal temperature is consistent, solves the head Re Zui cold glue
The pin shell glue injection mold of problem.
To achieve the goals above, the utility model provides the following technical solutions:
A kind of no mouth of a river pin molds, including upper die and lower die, the upper mold include the panel set gradually from top to bottom,
Hot runner manifold and cope plate are provided with positioning ring on the panel, flow distribution plate, the flow distribution plate are provided in the hot runner manifold
It is inside provided with runner, the bottom of the flow distribution plate is provided with hot nozzle main body, and the upper end of the hot nozzle main body is connected with runner
It connects, upper cores is provided in the cope plate, the lower end of the hot nozzle main body is protruded into upper cores, is also set in the hot nozzle main body
It is equipped with beryllium copper core, heating wire is additionally provided between the beryllium copper core and hot nozzle main body, the lower die includes successively setting from top to bottom
Push plate, lower template, supporting plate, thimble panel, Ejector Retainer Plate and the bottom plate set are provided with lower mode in the lower template.
Further, the top of the flow distribution plate is mounted in hot runner manifold by heat-insulated meson.
The utility model has the following beneficial effects:
The utility model is provided with the better beryllium copper core of heating conduction, and beryllium copper core penetration heat nozzle master in hot nozzle main body
Body increases the heat-conducting area of beryllium copper nozzle core, and beryllium copper core is enable to be warming up to set temperature in a short time, and beryllium copper core is whole nozzle
Core guarantees that beryllium copper core bulk temperature is consistent, solves the problems, such as that the head Re Zui is easy cold glue.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model pin shell；
Fig. 2 is the structural schematic diagram of the utility model；
Fig. 3 is the structural schematic diagram of the hot nozzle main body of the utility model.
Specific embodiment
The utility model is further described below in conjunction with attached drawing:
It is as shown in Figures 2 to 3, a kind of no mouth of a river pin molds, including upper die and lower die, the upper mold include on to
Under the panel 11, hot runner manifold 12 and the cope plate 13 that set gradually, be provided with positioning ring 14, the hot flow path on the panel 11
It is provided with flow distribution plate 15 in plate 12, runner 18 is provided in the flow distribution plate 15, the bottom of the flow distribution plate 15 is provided with heat
The upper end of nozzle main body 16, the hot nozzle main body 16 is connected with runner 18, and upper cores 17, institute are provided in the cope plate 13
The lower end for stating hot nozzle main body 16 is protruded into upper cores 17, and beryllium copper core 19, the beryllium copper core are additionally provided in the hot nozzle main body 16
Heating wire 112 is additionally provided between 19 and hot nozzle main body 16, the lower die includes the push plate 21 set gradually from top to bottom, lower die
Plate 22, supporting plate 23, thimble panel 24, Ejector Retainer Plate 25 and bottom plate 26 are provided with lower mode 27 in the lower template 22.
Further, the top of the flow distribution plate 15 is mounted in hot runner manifold 12 by heat-insulated meson 111.
The utility model is provided with the better beryllium copper core of heating conduction, and beryllium copper core penetration heat nozzle master in hot nozzle main body
Body increases the heat-conducting area of beryllium copper nozzle core, and beryllium copper core is enable to be warming up to set temperature in a short time, and beryllium copper core is whole nozzle
Core guarantees that beryllium copper core bulk temperature is consistent, solves the problems, such as that the head Re Zui is easy cold glue.
The above is not limit the technical scope of the present invention, all according to the utility model technical spirit
To any modification, equivalent variations and modification made by above embodiment, the model of the technical solution of the utility model is still fallen within
In enclosing.
