The mold cooling system capable of controlling the temperature difference of the mold temperature is characterized in that a gap (201) is arranged on the fixing section, inside the mold core (1), of the insert (2), a sealing ring (3) is installed at the contacting position of the insert (2) and the mold core (1), a heating pipe (4) is installed inside the insert (2), a cooling water way (5) is arranged on the mold core (1), the gap (201) on the fixing section is communicated with a helium box (7) in the outer world through a helium pipeline (6) on the mold core (1), and a heat insulation board (8) is installed on the bottom of the insert (2). According to the mold cooling system capable of controlling the temperature difference of the mold temperature, steel materials with low heat conductivity coefficient is chosen, controlling of high and low temperature in a cavity of a mold can be achieved by adopting ceramic heat insulation coating and filled nitrogen heat insulation technology, and accordingly when a plastic mold is formed, different mold temperature can be kept at different areas of the mold according to forming needs, and heating exchanging cannot occur.
Description
Technical field
The utility model belongs to the injection molding technology field, specifically just relate to a kind of can be according to the mold cooling system that is injection molded into the sexual needs control mould temperature temperature difference.
Background technology
Injection molded is a kind of important means of product shaping, injection molded is to utilize the plastic material principle that shape changes under HTHP, use plastic mould various plastic materials to be made into the process of the needed product of people, in general, plastic mould is the built-up plastics mould for compression moulding, extrusion molding, injection, blowing and low foaming, it mainly comprises dynamic model, cover half and core rod, is equipped with die cavity on dynamic model and the cover half, and core rod is housed in the die cavity.Existing common plastic mould all is to form after injecting plastic mould by injection machine after the melting of plastic cement raw material.
The existing injection mold that is shaped some precision engineering structural member need to have in different zones different mould temperature sometimes, in order to adjust molding technique parameter, reaches the purpose of making high-quality plastic cement products.Particularly for many material (plastic cement+plastic cement, plastic cement+silica gel etc.) product shaping mould, difference because of raw-material substance characteristics itself, cause the temperature difference of the zones of different in mould inner mould chamber can be very large, simultaneously, for guaranteeing the quality of product, the zone that these mould temperature are different needs again each self-constant temperature and heat exchange does not occur as far as possible.And the traditional moulds cooling system, because the thermal conductivity factor of die steel is high, the shape matching of plastic parts is complicated, at different mold inserts, realizes in the zones of different that the temperature control of height mould does not occur that the heat conduction is difficult to realize.
The utility model content
Need to guarantee the defective of the heat insulation and constant temperature of each mould warm area in the time of can't being applicable to many materials product shaping for the cooling system of above-mentioned existing plastic mould, the utility model provides a kind of mold cooling system of controlling the mould temperature temperature difference, adopt the special dies cooling system structure, when plastic mould is shaped, the mould zones of different keeps not isotype temperature according to the shaping needs, and heat exchange does not occur.
Technical scheme
In order to solve above-mentioned technical barrier, a kind of mold cooling system of controlling the mould temperature temperature difference of the utility model design, it comprises die, the shaping mold insert is contained in the die, it is characterized in that: the canned paragraph of described mold insert in die is gapped, and mold insert and die contact position are equipped with sealing ring, heating tube is housed in the mold insert, have cooling water channel on the die, the canned paragraph gap communicates by the helium tank of the helium pipeline on the die with the external world, and thermal insulation board is equipped with in the mold insert bottom.
Further, the gap of described mold insert canned paragraph in die is at 0.5～3mm.
Further, described cooling water channel is symmetrically distributed in the mold insert both sides.
Further, described die adopts the low thermal conductivity steel to make, and mold insert scribbles ceramic heat insulating coating outward.
Beneficial effect
The utility model is selected the steel of low thermal conductivity, adopt ceramic heat insulating coating and filling nitrogen-gas heat-insulating technique to realize the control of high and low temperature in the mold cavity, when plastic mould was shaped, the mould zones of different kept not isotype temperature according to the shaping needs, and heat exchange does not occur.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described further.
As shown in Figure 1, a kind of mold cooling system of controlling the mould temperature temperature difference, it comprises die 1, and shaping mold insert 2 is contained in the die 1, and wherein, the canned paragraph of described mold insert 2 in die 1 has the gap 201 of 0.5～3mm.Mold insert 2 and die 1 contact position are equipped with sealing ring 3, and heating tube 4 is housed in the mold insert 2, have cooling water channel 5 on the die 1, and canned paragraph gap 201 communicates by the helium tank 7 of the helium pipeline 6 on the die 1 with the external world, and thermal insulation board 8 is equipped with in mold insert 2 bottoms.
Described cooling water channel 5 is symmetrically distributed in mold insert 2 both sides.
Described die 1 adopts the low thermal conductivity steel to make, the mold insert 2 outer ceramic heat insulating coatings that scribble.
Die 1 is low-temperature space, reach needed mold temperature by traditional cooling water channel 5, mold insert 2 is high-temperature regions, reach required mold temperature by heating rod 4, for making these two each self-constant temperature of district and avoiding as far as possible heat exchange, at first mold insert 2 is selected the steel of the thermal conductivity factor of passing at the low, and carries out ceramic heat insulating coating on the mold insert surface that contacts with low-temperature space and process.For preventing that better heat from exchanging, the contact-making surface of high low-temperature space mold insert is the least possible, and noncontact face is designed to the sealing area of empty avoiding, utilizes filling nitrogen to realize that gas is heat insulation, and the heat conduction is reduced to minimum.For the injection pressure that can bear mold insert 2 bottom surfaces with avoid heat to be delivered to following template.Adopt special thermal insulation board 8 to make cover plate.
The utility model is selected the steel of low thermal conductivity, adopt ceramic heat insulating coating and filling nitrogen-gas heat-insulating technique to realize the control of high and low temperature in the mold cavity, when plastic mould was shaped, the mould zones of different kept not isotype temperature according to the shaping needs, and heat exchange does not occur.
