Abstract
The utility model discloses a runner structure for a kirsite pressure casing mould, which comprises a fixed template and a movable template. A nozzle and a cup slipcover are arranged in the fixed template. The outside of the nozzle is connected with a thermal fuse. A horizontal conical channel is arranged in the cup slipcover. A flow guiding block is arranged in the fixed template. The end face formed by attaching the fixed mould and the movable mould is correspondingly provided with two semi-circular channels vertically arranged. The semi-circular shaped channels are connected with the conical channel through an arc channel. The fixed template has no need for a spreader. The nozzle can be heated to above 400 DEG C by the thermal fuse so that zinc liquid can not solidify in the cup slipcover. The zinc liquid enters a circular channel formed by attaching the two templates and are popped out after being cooled. The cross section of the runner is a circle. Because the area is smaller, heat loss and surface resistance are reduced to the lowest level. Compared with the existing general trapezoid design, the cylinder shape is superior. The runner structure for the kirsite pressure casing mould has no solidified direct runner, thereby greatly reducing the weight of the runner.
Description
Technical field
The utility model relates to the improvement of the hot runner structure of die casting in the zinc alloy diecasting technical field.
Background technology
Running channel (mouth of a river) especially sprue (ice cream tube) is the part of foundry goods, though there is not profit to be worth, is unavoidable in process of production.With 160 tons of hot chamber machines is example, and each production produces 150 gram running channels (not comprising overflow well) at least, supposes that factory produces with class Three, and the production cycle is 20 seconds, and the machine utilization rate is 80%, and the generation of then annual cast gate running channel reaches 190 tons; With one 80 tons die casting machines is example, and then each production will produce 100 gram running channels, and the production cycle, then the down annual running channel that produces of equal conditions was more above 210 tons if change 12 seconds into.This shows that the running channel design has become the key factor that influences production cost.
Have the trapezium structure that mostly is of running channel now, little greatly the time when flow profile changes, exist the dead angle to be easy to generate cold shut, be unfavorable for the foundry goods that surface requirements is higher, the rapid bending of cross gate and sprue can cause eddy current and bias current as shown in Figure 1, fill up above-mentioned curve, just need to use bigger pressure, can cause overlap so again to offset the high pressure loss, reduce casting dimension accuracy, shorten die life, eddy current volume conductance causes and occurs pore in the foundry goods in addition, can bubble when plating or baking vanish.
The utility model content
The purpose of this utility model provides a kind of simple in structure, main shaft cooling body that cooling effectiveness is high.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of running channel structure of zinc alloy diecasting mould, comprise solid plate and moving platen, be provided with nozzle and glass holder in the solid plate, nozzle is externally connected with heating wire, be provided with in the glass holder level to tapered channel, be provided with baffle in the moving platen, correspondence is provided with vertical two semi-circular channel on the end face that solid plate and moving platen fit, and two semi-circular channel are connected with tapered channel by curved channel.
The beneficial effects of the utility model are: no longer need the branch flow cone on the moving platen, nozzle can be heated to more than 400 ℃ by heating wire, makes zinc liquid can not solidify in glass holder, and zinc liquid enters the circular channel that two templates are fitted and formed, cooling back die sinking ejects, running channel of the present utility model cross section is circular, because area is less, makes heat loss, skin resistance minimize, the trapezoidal design general with respect to now, cylindrical more apparent superior, there is not the sprue of fixed line, greatly reduce running channel weight.
Description of drawings
Fig. 1 is the schematic diagram of existing flow passage structure;
Fig. 2 is the schematic diagram of the utility model flow passage structure.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
With reference to shown in Figure 2, the utility model discloses a kind of running channel structure of zinc alloy diecasting mould, comprise solid plate 1 and moving platen 2, be provided with nozzle 7 and glass holder 3 in the solid plate 1, nozzle 7 is externally connected with heating wire, be provided with in the glass holder 3 level to tapered channel 5, be provided with baffle 4 in the moving platen 2, correspondence is provided with vertical two semi-circular channel 6 on the end face that solid plate 1 and moving platen 2 fit, two semi-circular channel 6 are connected with tapered channel 5 by curved channel, owing to no longer need the branch flow cone on the moving platen 2, nozzle 7 can be heated to more than 400 ℃ by heating wire, make zinc liquid can in glass holder 3, not solidify, zinc liquid enters the circular channel that two templates are fitted and formed, cooling back die sinking ejects, running channel of the present utility model cross section is circular, because area is less, make heat loss, skin resistance minimizes, the trapezoidal design general with respect to now, cylindrical more apparent superior, there is not the sprue of fixed line, greatly reduce running channel weight, flow passage structure has shortened the cold flow journey greatly, avoids producing cold line, helps producing the foundry goods of being had relatively high expectations in the surface.
Flow passage structure of the present utility model has following advantage:
1, shortened the production cycle: the running channel of hot flow path is little than traditional design, and does not have sprue to need cooling, can shorten the die sinking time, also makes product stripping more smooth and easy simultaneously, has improved the speed of producing, and especially the effect with thin-wall part is more obvious.
2, reduce material slag and material damage.
3, need not often to change the machine nozzle:, avoided because of changing a large amount of generation times that thermal work parts is wasted because the sprue that hot flow path does not solidify uses bigger nozzle diameter can cover different mould cast requirements.
4, save the energy, reduce material cost, can avoid stacking a large amount of cast gates simultaneously, make the workshop cleaner and tidier.
5, reduced toxic emission, it is particularly important that factory is satisfied the environmental regulation that tightens up day by day.
6, reduced eddy current volume gas, reduced the pore of product, husky hole and the needs of slime flux well.
7, the cold flow journey of hot flow path significantly shortens, and the pressure consume minimizes.
8, reduce defectives such as product cold shut, water wave, improved the quality of product.
9, by thermocouple control hot-fluid glass holder and baffle temperature, be more conducive to technology controlling and process and steady production efficient.
The foregoing description is illustrative principle of the present utility model and effect thereof only; and the embodiment of part utilization; for the person of ordinary skill of the art; under the prerequisite that does not break away from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
