Background technology
Molding cycle when the plastic mould work of injection molding generally comprises molding, injection, pressurize, cooling, die sinking, system
Product take out etc. the stages, mold is heated after molding, mold is made to be rapidly heated, injection, packing stage also will be to mold
It is kept the temperature, to increase the mobility of melten gel, so that melten gel is filled each corner of mold cavity, it is ensured that product quality may be used also
Shorten molding cycle, improves productivity；After the completion of packing stage, needs to be quickly cooled down to shorten molding cycle, improve production
Rate may also suppress product defects, reduce the generation of defective products, improve the exterior quality of product.Plastic mould commonly do by heating
Method is that electrical bar is arranged in mold, so that electrical bar is generated heat electrical bar energization, the heat of electrical bar is made to be conducted to plastic mould；
Common cooling method is that cooling water channel is opened up in mold, and the heat of mold is taken away using the cooling water circulated.Due to
After cooling stage, remaining cooling water is not discharged in cooling water channel, is carried out to plastic mould in next molding cycle
When heating, not only mold body is heated, also remaining cooling water in cooling water channel is heated, due to cooling
Coolant-temperature gage is relatively low, in addition the specific heat capacity of water is very big（For 4200J/ (kg DEG C)）, mold materials are generally steel, and specific heat capacity is smaller（For
460J/(kg℃)）, remaining cooling water can not only absorb a large amount of heat in cooling water channel, influence plastic mould and be rapidly heated,
The vapor that high temperature and pressure can also be become after cooling water is heated destroys cooling water channel, cooling water inlet and outlet pipes and is arranged in cooling
Valve in water inlet and outlet pipes, shortens the working life.
Invention content
The present invention overcomes the deficiencies in the prior art, provide a kind of plastic mould nonstorage calorifier, can be to plastic mold
Tool is quickly heated, and remaining cooling water in plastic mould cooling water channel can also be discharged, avoid because remaining in cooling water channel
Cooling water destroys cooling water channel, cooling water inlet and outlet pipes and valve in the heated vapor for becoming high temperature and pressure of next molding cycle
Door, prolongs the service life.
The present invention is achieved by the following technical solutions：
A kind of plastic mould nonstorage calorifier, including cooling water inlet pipe, cooling water outlet pipe, plastic mould, mold water inlet pipe and
Mold outlet pipe；The external cooling water generating device in one end of the cooling water inlet pipe and cooling water outlet pipe；In the plastic mould
Equipped with cooling water channel and electric heater unit；One end of the water inlet connecting mold water inlet pipe of the cooling water channel, water outlet connection
One end of mold outlet pipe；Further include compressed air hose, inlet triplet for water solenoid valve, outlet three way solenoid valve, drainpipe and control
Device；One end external compressed air generating means of the compressed air hose, the other end connect inlet triplet for water solenoid valve first into
Mouthful；The other end of the cooling water inlet pipe of the second import connection of the inlet triplet for water solenoid valve, exports the another of connecting mold water inlet pipe
One end；The other end of the import connecting mold outlet pipe of the outlet three way solenoid valve, first outlet connect cooling water outlet pipe
The other end, second outlet connect one end of drainpipe；The external cistern of the other end of the drainpipe；The electric heater unit is
PTC electric-heating belts；The inlet triplet for water solenoid valve, outlet three way solenoid valve and PTC electric-heating belts are electrically connected with the controller simultaneously
It is controlled by it；The controller external power supply.
Further, it is equipped with insulating layer outside the cooling water inlet pipe.It can reduce and carry out heat exchange with external environment, keep low
Temperature state.
Further, the PTC electric-heating belts are annularly arranged in plastic mould.Heating effect can be strengthened.
The beneficial effects of the invention are as follows：Plastic mould is heated using PTC electric-heating belts, quick heating, it can also be automatic
Control temperature；Using inlet triplet for water solenoid valve, outlet three way solenoid valve, high-pressure air tube and drainpipe, cooled down in plastic mould
After stage, the cooling water remained in cooling water channel is blown away rapidly using compressed air, plastic mould can not only be carried out
Quickly heating also can avoid because the heated vapor for becoming high temperature and pressure of remaining cooling water destroys cooling water in cooling water channel
Road, cooling water inlet and outlet pipes and valve, prolong the service life.
Description of the drawings
Fig. 1 is the structural diagram of the present invention.
Specific implementation mode
As shown in Figure 1, the embodiment of the present invention, a kind of plastic mould nonstorage calorifier, including it is cooling water inlet pipe 1, cold
But outlet pipe 2, plastic mould 3, mold water inlet pipe 4 and mold outlet pipe 5；The one of the cooling water inlet pipe 1 and cooling water outlet pipe 2
Hold external cooling water generating device；Cooling water channel 6 and electric heater unit 7 are equipped in the plastic mould 3；The cooling water channel 6
8 connecting mold water inlet pipe 4 of water inlet one end, one end of 9 connecting mold outlet pipe 5 of water outlet；It further include compressed air hose
10, inlet triplet for water solenoid valve 11, outlet three way solenoid valve 12, drainpipe 13 and controller 14；The one of the compressed air hose 10
External compressed air generating means, the other end is held to connect the first import 15 of inlet triplet for water solenoid valve 11；The inlet triplet for water electricity
The other end of the second import 16 connection cooling water inlet pipe 1 of magnet valve 11, exports the other end of 17 connecting mold water inlet pipes 4；It is described
The other end of the 18 connecting mold outlet pipe 5 of import of outlet three way solenoid valve 12, first outlet 19 connect the another of cooling water outlet pipe 2
One end, second outlet 20 connect one end of drainpipe 13；The external cistern of the other end of the drainpipe 13；The electrical heating dress
It is PTC electric-heating belts to set 7；The inlet triplet for water solenoid valve 11, outlet three way solenoid valve 12 and PTC electric-heating belts 7 with control
