Abstract
The utility model relates to the field of moulds, in particular to a mould feeding device for injection moulded shoes, which comprises an injection hole, a flow channel, a sprue and a cold slug well, wherein the diameter of the sprue is more than that of a nozzle hole of an injection molding machine by 0.5mm-1mm, and if not, a dead angle can be formed during injection moulding, material can be accumulated, and injection pressure is lost; the flow channel is arranged in a bottom die; the sprue is communicated with the flow channel and a die cavity; the inclination of the connecting part between the sprue and the flow channel is 30-60 degrees; the sprue is a taper hole, so that cold charge in the flow channel can be conveniently broken at the connecting part when being demoulded; and the cold slug well is arranged at the tail end of the flow channel. Due to the structure, the mould feeding device avoids the quality problem of cold shut or cold slug of the injection moulded shoes, residual molten plastic is less, the cold charge is conveniently demoulded, and the mould feeding device can be used for containing the cold charge generated when injection is started and removing cold air.
Description
Technical field
The utility model relates to mould applications, is specifically related to a kind of injection moulded shoes die feeding device.
Background technology
Injection moulded shoes is in China's shoe industry, and output or kind all account for larger proportion, changes for the continual renovation that adapts to the injection moulded shoes kind, and product quality improves constantly, and therefore requires the quality kind of injection moulded shoes mould also corresponding development must be arranged.The correctness of the feed system Design and Machining of injection moulded shoes mould directly influences the quality of injection moulded shoes, and the effect of injection moulded shoes die feeding system is the molten plastic that makes from the injector barrel; Stable and flow into smoothly and be full of whole footwear model cavities; Each position of simultaneously, in being full of the process of mould, injection pressure being transmitted die cavity is to guarantee the complete moulding of sole, the feed system of injection moulded shoes mould; Usually form by geat, runner, cast gate; But be prone to quality problems such as cold shut or cold spot when runner is long, residual molten plastic is many, cold burden demoulding inconvenience.
Summary of the invention
The purpose of the utility model provides a kind of injection moulded shoes die feeding device, and this device can be avoided the appearance of cold shut or cold spot quality problems.
A kind of injection moulded shoes die feeding device comprises geat, runner, cast gate, and slag well, and the diameter of said geat is than the big 0.5～lmm of injection machine nozzle bore diameter, otherwise can cause the dead angle during injection moulding, and accumulates material, the loss injection pressure; Said runner is located in the bed die, and said cast gate is communicated with runner and die cavity, and the gradient of said cast gate and runner connecting portion is 30～60 degree, and said slag well is located at flow field end.
Said cast gate is a tapered hole, when being convenient to the cold burden demoulding in the runner, breaks off from the junction; Said cross section of fluid channel is has circle or semicircle.
Owing to be provided with said structure, this device can make injection moulded shoes avoid the appearance of cold shut or cold spot quality problems, and residual molten plastic is few, and cold burden is convenient in demoulding, and can hold the cold burden that produces when injection begins and get rid of cold air.
Description of drawings
Fig. 1 is the structural representation of a kind of injection moulded shoes die feeding device of the utility model.
The specific embodiment
As shown in Figure 1, a kind of injection moulded shoes die feeding device comprises geat 1, runner 2, cast gate 3 and slag well 4; The diameter of said geat 1 is than the big 0.5～lmm of injection machine nozzle bore diameter; Otherwise can cause the dead angle during injection moulding, and accumulate material, the loss injection pressure; Said runner 2 is located in the bed die 11, and said cast gate 3 is communicated with runner 2 and die cavity 12, and the gradient of said cast gate 3 and runner 2 connecting portions is 30～60 degree, and said slag well 4 is located at runner 2 ends.Said cast gate 1 is a tapered hole, breaks off from the junction when being convenient to the cold burden demoulding in the runner 2; Said runner 2 cross sections are has circle or semicircle.
