The utility model is further described in detail below through specific implementation examples and in conjunction with the accompanying drawings.

Fig. 1 is the structure diagram of double-deck ox horn type running channel that the utility model embodiment provides；Fig. 2 is the utility model The side view for the double-deck ox horn type running channel that embodiment provides.

A kind of double-deck ox horn type running channel provided as Figure 1-Figure 2 for the utility model embodiment, including main runner 100th, cow glue powder 200 and the secondary runner 300 connected with main runner 100；Cow glue powder 200 includes the first cow glue powder 201 and second cow glue powder 202, the first cow glue powder 201 connected with main runner 100, the second cow glue powder 202 and time shunting Road 300 connects；The diameter of main runner 100 is more than the diameter of time runner 300.

A kind of double-deck ox horn type running channel that the utility model embodiment provides, including main runner 100, cow glue powder 200 The secondary runner 300 connected with main runner 100, wherein cow glue powder 200 include the first cow glue powder 201 and the second ox horn Cast gate 202, the first cow glue powder 201 are connected with main runner 100, and the second cow glue powder 202 is connected with time runner 300, main The diameter of runner 100 is more than the diameter of time runner 300, to ensure flow equilibrium during product injection moulding, and passes through First cow glue powder 201 and the second cow glue powder 202 can be with rapid processing elongate in shape class packet flexible glue products 600, and are adopting After cow glue powder 200, it is possible to reduce the quantity of hot-runner nozzle reduces the purchase cost of hot flow path, with hot-runner nozzle The reduction of quantity, cast gate quantity can also be reduced therewith, so as to reduce the waste of material, reduce production cost, but also can drop The risk deformed after when low mold is long-term, so as to reduce the exploitation of mold, use cost on the whole.

Moreover, using cow glue powder 200, it can be farther with the distance being left into the position of point, and selected into the position of point Can be more flexible, and stress drop is also relatively small.

Specifically, by using cow glue powder 200, when producing elongate in shape class packet flexible glue product 600, can set more A cow glue powder 200, and supplied, therefore can effectively reduce the number of hot-runner nozzle using single or several nozzles Amount.

Because reducing the quantity of hot-runner nozzle, in the development process of mold, development cost can be reduced；And And because of the reduction of the quantity of hot-runner nozzle, it is possible to reduce the fluting quantity of mold improves the intensity of mold, raw in long-time In production, the deformation of mold will not be caused under the action of injection pressure.

With the reduction of hot-runner nozzle quantity, the hot flow path mounting groove of mold cavity can also reduce, so as to increase template Intensity reduces template deformation risk, so as to promote product volume production qualification rate.

And the gate portions of cow glue powder 200 make standard component, and it is readily replaceable, therefore maintenance is relatively easy easily；And And in demoulding, cast gate is automatically separated with mold；Simultaneously mounting height can be adjusted using standard gate device cushion block.

Because to be produced to strip class flexible glue encapsulated products, therefore two cow glue powders are set in same section 200, the first cow glue powder 201 and the second cow glue powder 202 connect respectively with runner, the axis of the first cow glue powder 201 and Second cow glue powder 202 is separately positioned on the different opposite faces of product, and setting in this way can quickly produce product.

In the alternative of the present embodiment, the axis of the axis of the first cow glue powder 201 and the second cow glue powder 202 is located at Same plane, and the first cow glue powder 201 is identical with the direction of the second cow glue powder 202.

The axis of the axis of first cow glue powder 201 and the second cow glue powder 202 is generally aligned in the same plane, i.e., the first ox horn pours 201 and second cow glue powder 202 of mouth is located in same section, stress is avoided as topic, with strip class flexible glue encapsulated products length Difference, multigroup first cow glue powder, 201 and second cow glue powder 202 can be set, be molded while multistage is multi-faceted Work.

In the alternative of the present embodiment, 201 exit of the first cow glue powder and 202 exit of the second cow glue powder are apart 15mm-30mm.

Because the first cow glue powder 201 and the second cow glue powder 202 are simultaneously processed strip class flexible glue encapsulated products Work if the exit of both the first cow glue powder 201 and second cow glue powder 202 is far apart, can cause to be injection moulded The imbalance of Shi Liudong causes product quality relatively low, it is therefore desirable to 202 liang of the first cow glue powder 201 and the second cow glue powder The exit distance of person is defined.

Specifically, 201 exit of the first cow glue powder and 202 exit of the second cow glue powder be at a distance of 15mm-30mm, In the range of this, it is ensured that mold works normally, and ensures the quality of production product.

In the alternative of the present embodiment, secondary runner 300 includes for the first time runner 301 of injection and for receiving Collect second of runner 302 of waste material；First time runner 301 is connected with main runner 100, second of runner 302 and One time runner 301 connects；First time runner 301 and second of runner 302 coordinate T-shaped.

Wherein, secondary runner 300 includes for the first time runner 301 of injection and for collecting second of waste material point Runner 302, first time runner 301 are connected with main runner 100, and first time runner 301 is identical with second of flow diameter.

Meanwhile first time runner 301 and second of runner 302 coordinate T-shaped, can improve stress problem, make material Expect smooth flow.

In the alternative of the present embodiment, 201 port of the first cow glue powder goes out to be connected with second of runner 302.

And to ensure normal work of the melted material in the first cow glue powder 201, in the import of the first cow glue powder 201 Second of runner 302 of place's setting, production is inserted when can ensure that product is filled by second of runner 302 without defective material or cold burden In product cavity, second of runner 302 plays the role of storing waste material.

Moreover, second of runner 302 is connected with first time runner 301, the first runner is the first cow glue powder 201 Raw material is provided, second runner 302 stores waste material for the first cow glue powder 201, when ensureing the filling of the first cow glue powder 201 without Defective material or cold burden are entered in product.
