Be incorporated to description and form a part for description drawings describe aspects more of the present invention, and it is together with the description for explaining principle of the present invention, in the accompanying drawings:
Fig. 1 is the cross section of the simplification of hot reservoir portion, and it describes the formation of film on bank wall of hot melt material;
Fig. 2 is the perspective view of an embodiment of hot bank;
Fig. 3 is the cross section diagram of the hot bank of Fig. 2; And
Fig. 4 is the perspective view of the second embodiment of hot bank.
Detailed description of the invention
Although the present invention will be described in conjunction with some preferred embodiment, be not intended to be limited to these embodiments.On the contrary, it is intended to cover all alternative schemes in the spirit and scope of the present invention that are covered by and are defined by the following claims, amendment and equivalent.
Fig. 2 and 3 describes for device for producing molds and particularly uses hot melt material to carry out the hot bank 100 of the improvement of the device for producing molds of molding.Such device for producing molds also can be described as hot melt material processor.Hot bank 100 comprises upper curtate 102 (also referred to as extension of section 102) and lower heated zones 104 (also referred to as there being finless parts 104).
Treat that the hot melt material of molding will enter hot bank 100 by upper curtate 102.Upper curtate 102 defines internal reservoir chamber 105 (not having this label in accompanying drawing), for storing the hot melt material of powder/particle form to be melted in a large number.
The hot melt material of powder/particle form by have in finless parts 104 by be adjacent to finless parts 104 or the heater 106 be integrated in wherein heat and melt.Describe the heater 106 being attached to finless parts 104 in figs 2 and 3 in simplified schematic form.In some embodiments, heater 106 can be tubulose, and around there being a part for finless parts 104.Have finless parts 104 can comprise multiple fin or runner, these fins or runner form web material to increase the surface area being exposed to hot melt material, thus improve melting efficiency and the uniformity of hot bank 100.
As a rule, for holding the volume of hot melt material and having the structure of finless parts 104 and heater 106 to be configured to, make the material of the amount of expectation that finless parts 104 will accommodate in finless parts 104.The have size of finless parts 104 and configuration like this make heater 106 provide the heat of correct amount to there being finless parts 104, thus melt a certain amount of hot melt material at time per unit.
The hot melt material of fusing will spray from shower nozzle 108.
The problem found in prior art, that is, avoid producing the film of material and material film that particularly superheated is such, and upper curtate 102 adopts the not sticky material of insulation to make.Lot of materials is added into hot bank 100 by this permission, and eliminates the vertical wall 112 of material along upper curtate 102 before being with finless parts 104 and melt.
The temperature that the insulation provided will prevent wall 112 to be heated to melt the hot melt material be stored in upper curtate 102.By preventing material from melting, when material is flowed to had finless parts 104 by upper curtate 102, the inner surface not along wall 112 is formed film.The inner surface preventing material at wall 112 is also piled up by not sticky feature.
In described embodiment, upper curtate 102 is attached to and the keyset 114 having finless parts 104 to be connected.Keyset 114 has the lower flange portion 116 be configured to there being the upper end of finless parts 104 to match, and is configured to the upper flange portion 118 of matching with the lower end of upper curtate 102.
In some embodiments, can by keyset 114 with have finless parts 104 to merge to be formed as single.
In one embodiment, upper curtate 102 is formed by polytetrafluoroethylene (PTFE) (PTFE) or analog material, the high density polyethylene (HDPE) (HDPEHD6909, or through engineering approaches PolyNLT, through engineering approaches UHMW) of such as polyether-ether-ketone (PEEK) or through engineering approaches (Engineered).Preferably, the material of upper curtate has the thermal conductivity being less than 5W/m-K.In addition, the material of upper curtate should have the coefficient of friction of 0.03 to 0.5.
The upper end of hot bank 100 and particularly upper curtate 102 can be configured to receive lid or be connected to larger volume for supplying the supply system not melting powder/particle hot melt material.
Fig. 4 describes an alternative of hot bank 200.This hot bank is similar to hot bank 100 before, and difference is, it is configured to accept nitrogen feeding to reduce the oxidation of intrasystem hot melt material.
Upper curtate 202 comprises the mouth 203 being operationally coupled to nitrogen feed system 205.Nitrogen is fed in upper curtate 202, is in the top of any material stored in hot bank 200.From to there is air different, there is nitrogen in upper curtate 202 and suppression is oxidized.
In these two kinds of systems, system can utilize or not utilize pressure to carry out aid in material and be fed to such as pump or plunger from hot bank.
It should be noted that the not sticky material that upper curtate 102,202 need not be entirely formed as insulation.On the contrary, upper curtate 102,202 can be formed by multiple assembly, is formed by the not sticky material insulated to make the inner sleeve of contact powder/granule hot melt material.
