The specific embodiment
Below with reference to accompanying drawing, a kind of cold runner die for the moulding of thermosetting engineering material of the present utility model is elaborated.
Referring to Fig. 2, in the present embodiment, a kind of cold runner die for the moulding of thermosetting engineering material, comprising: mold 1; Runner 2, is extended downwards by the upper surface of described mold 1, and the initiating terminal of described runner 2 forms injection port; Die cavity 3, is formed in described mold 1, and it is used to form the profile of product; Runner 4, for being communicated with described runner 2 and die cavity 3 described in each, imports respectively each die cavity 3 by the fluid in described runner 2; Heating component 5, contiguous described die cavity 3, for making the temperature of described die cavity 3 be kept above the solidification temperature of thermosets; Also comprise and suppress described heater block 5 to runner 2 and the heat conducting insulating assembly 6 of runner 4.
The heat effect that is arranged so that 5 pairs of die cavitys of heating component of insulating assembly 6 is not easy to described runner 2 and the interior transmission of runner 4, thereby make runner 2 and the temperature in runner 4 can remain on thermosets solidification temperature following (40 ℃～90 ℃), thereby it is interior curing that fluid is difficult at runner 4 and runner 2, therefore reduced wastage of material; And because fluid is difficult for solidifying in runner 2 and runner 4, thus make flow resistance little, be not easy to stop up, so fluid easily enters die cavity 3, can improve the yields of product.
In the present embodiment, described insulating assembly 6 arranges between the connection position 7 of described runner 2 and runner 4 and described die cavity 3.The runner 2 of die cavity 3 one side positions and the fluid of runner 4 are difficult for being subject to heat cure to be dorsad positioned at insulating assembly 6, and be arranged in insulating assembly 6, towards the fluid of the runner 4 of die cavity 3 one side positions, through the preheating of heating component 5, enter die cavity 3 and easily reach fast solidification temperature, therefore, be provided with like this and help enhance productivity.
It should be noted that, the concrete structure of described insulating assembly 6 is diversified, as long as can guarantee that being difficult for carrying out heat between runner 2 and runner 4 and die cavity 3 conducts, in the present embodiment, for the ease of installing, described insulating assembly 6 is thermal insulation board, and the mode that described thermal insulation board is interlayer is arranged in described mold 1, on it, corresponding runner 4 offers through hole, so that the fluid in runner passes through.
In the present embodiment, described runner 2 and described runner 4 be positioned at described insulating assembly 6 dorsad the part of die cavity 3 one sides be cold runner, described cold runner is for keeping below the fluid temperature (F.T.) that is positioned at cold runner the solidification temperature (40 ℃～90 ℃) of described thermosets.Keep cold runner inner fluid temperature a lot of lower than the means of thermosets temperature, for example, by above-mentioned thermal insulation board is set, suppress the heat of heating component 5 and transmit.
In the present embodiment, in order further to improve the stability of temperature in cold runner, also comprise cooling assembly 8, the contiguous described cold runner setting of this cooling assembly 8, for the fluid in described cold runner is lowered the temperature, cooling assembly 8, due to contiguous cold runner setting, therefore easily and between cold runner carries out heat exchange, makes temperature in described cold runner remain on the solidification temperature following (40 ℃～90 ℃) of thermosets.Cooling assembly 8 the further control with runner 4 interior temperature to runner 2 that guaranteed is set, the temperature that staff can regulate in runner 2 and runner 4 by cooling assembly 8, so that in the temperature range of fluid wherein in good fluidity, contribute to fluid to enter smoothly die cavity 3, enhance productivity and yields.
It will be appreciated that, insulating assembly 6 mode that the part of die cavity 3 one sides is set to cold runner is dorsad not limited only to above-mentioned contiguous cold runner position cooling assembly 8 these a kind of modes is set, for example, can also be by the louvre that easily makes heat shed being set near the cold runner of die cavity 3 one sides dorsad; Or the mode extend the heat conduction pin outside mold is set near cold runner, aforesaid way all can so that insulating assembly 6 dorsad the part of die cavity 3 one sides become cold runner.
Further, described cooling assembly 8 is for being arranged on the cold water pipes in described mold 1.
Below in conjunction with Fig. 2, describe the set-up mode of runner 2 and runner 4 in detail, in the present embodiment, described runner 4 comprise be arranged on described insulating assembly 6 dorsad die cavity 3 one sides and extend to die cavity 3 described in each directly over the horizontal component 9 of position, and be communicated with described horizontal component 9 extend to downward vertically the vertical component 10 in described die cavity 3.Because runner 4 comprises horizontal component 9 and vertical component 10, horizontal component 9 is arranged on insulating assembly 6 die cavity 3 one sides dorsad, so temperature is therebetween lower, and fluid is interior difficult the solidifying of described horizontal component 9, thereby it is smooth and easy that fluid is flowed; Because vertical component 10 is through described insulating assembly 6, under the effect of gravity, the comparatively smoothness that flows of vertical component 10 inner fluids, is not easy to stop up betwixt and has effectively avoided fluid blockage and wastage of material.
Further, described insulating assembly 6 also comprises the insulation for described heating component 5 and described vertical component 10 are isolated that is positioned at described vertical component 10 outsides, the insulation of vertical component 10 arranged outside can effectively suppress heat to the interior conduction of described vertical component 10, therefore further make fluid temperature (F.T.) therebetween remain on below the solidification temperature of thermosets, thereby make fluid be not easy to solidify, further avoided fluid blockage and wastage of material.
It will be appreciated that, suppress heating component 5 to the heat conducting mode of described vertical component 10, be not limited only in a kind of mode of vertical component 10 arranged outside insulation, and the set-up mode of described insulation is also diversified, such as surrounding in a tubular form described vertical component 10, arranges or be tabular, at vertical component 10 both sides lattice gears, set-up mode is set etc.; Simultaneously insulation can be one-body molded with insulating assembly 6 can be also to arrange respectively; Although do not go out in the accompanying drawings, those skilled in the art can understand by following description, and particularly, insulation is arranged on around vertical component 10, for suppressing heating component 5 to vertical component 10 heat conduction.
In the present embodiment, described heating component 5 is for being arranged on the electrothermal heating tube in described mold 1.It is fast that electrothermal heating tube has firing rate, the advantage that temperature is controlled.
In the present embodiment, described heating component 5 is located at described insulating assembly 6 towards a side of described die cavity 3, sets to be like this in, insulating assembly 6 better to suppress heating component 5 heat conduction with runner 4 to runner 2.
Obviously, above-described embodiment is only for example is clearly described, not the restriction to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without also giving all embodiments.And among the protection domain that the apparent variation of being extended out thus or change are still created in the utility model.
