The utility model provides a warm running way injection molding device for thermosetting plastics. Low temperature is kept in the running gate of a flow channel region.The plastic which is in plastic melting state is not solidified and thus can be injected continuously. A mold cavity is in high temperature state, causing the plastic to be solidified. The flow collecting cavity of the injection mold of the utility model comprises a main running gate, a main flow channel, a separated running gate and a separated flow channel through a heated board, an upper mold board, an upper flow channel board, a lower flow channel board, a positioning board, a heat insulating supporting board and a heat insulating positioning board, which sends the melting plastic into the mold cavity part composed of an upper mold cavity board and a lower mold cavity board. The main gate, the main flow channel, the separated running gate and the separated flow channel respectively heat and control the temperature of the melting plastic in the mold of each position of the flow collecting cavity and the mold cavity as needed. The utility model can achieve the purposes of saving energy, greatly saving materials and power, and reducing environmental pollution. The warm running way injection molding device for thermosetting plastics is very suitable for mass production of injection products such as phenol formaldehyde, melamine, melamine, epoxy, etc.
Description
Technical field
The utility model relates to the thermoset plastic forming technology, specifically is a kind of thermosetting plastics temperature running channel injection molding apparatus.
Background technology
The moulding of thermosetting plastics goods, with compression moulding and injection mo(u)lding, technology is to adopt injection mo(u)lding preferably.Relative compression moulding technology, injection mo(u)lding have the plastic dimensionally stable, the correction workload is little, are convenient to realize automated production, are applicable to production in enormous quantities, the production efficiency height; And can replace the heavy manual manual labor of moulding shaping process, reduce in the forming process solvent flashing to the infringement of human body.But each moulded parts of injection mo(u)lding, its useless waste material handle will account for 15%～25% of a mould, accounts for 60% sometimes, and this is very big waste.And thermosetting plastics waste material handle is insoluble not molten solidfied material, can not use repeatedly, generally buries processing, can produce new environmental pollution again.On thermoset articles is produced, must solve and boost productivity and product quality; Must solve the raw-material waste material handle problem of waste.Its inexorable law is the thermosetting plastics compression moulding thermosetting plastics injection mo(u)lding up till now by the past, and develops to the injection mo(u)lding of thermosetting plastic warm running channel again.
Summary of the invention
The purpose of this utility model provides in a kind of maintenance cast gate runner zone temperature makes thermosetting plastics be in that low temperature is moulded molten state so that the continuous injection molding thermosetting plastics temperature running channel injection molding apparatus of thermosetting plastics.
The utility model is taked following technical scheme: device comprises manifold and die cavity, and wherein the control of the temperature of manifold is in low temperature (80 ℃～120 ℃), and the thermosetting plastics of the manifold of flowing through is the molten state of moulding, and plastics do not solidify and can inject continuously; And die cavity is in electrical heating high temperature (180 ℃～200 ℃) so that plastic products solidify under this high temperature.Specifically be that wherein manifold is in this device cope match-plate pattern central authorities main cast gate to be set, following water flowing flat to sprue, sprue is divided into some runners again, and leads to separately branch cast gate by each runner, again by dividing a cast gate low-temperature spray nozzle to annotate to required die cavity.The position is provided with cope match-plate pattern on this shaped device, is covered with warming plate on the cope match-plate pattern surface, has the cave, chamber in cope match-plate pattern inside for mounting strap idol heater.Be equipped with the upper runner plate under the cope match-plate pattern, divide at the upper reaches guidance tape and deposit runner plate; On dirty guidance tape, have level to the sprue groove, and have some flow distribution plate chambeies that become vertical direction with sprue in sprue groove proper site.The equipped back of upper reaches guidance tape and dirty guidance tape location forms sprue.The utility model order from top to bottom supplies to settle main cast gate in warming plate, cope match-plate pattern, upper reaches guidance tape perforate.Have the cave, chamber at upper reaches guidance tape and lower flow channel intralamellar part and be with even low-temperature heater for settling.Below dirty guidance tape, location-plate is installed, and by location-plate each minute the gate orifice acupuncture point put the equipped cast gate low-temperature spray nozzle that divides.Divide the cast gate low-temperature spray nozzle also to be equipped with thermometric even summation band idol heating muff.Install cavity plate and lower impressions plate at location-plate in proper order below by heat insulation gripper shoe and heat insulation reference column.Aim at branch cast gate low-temperature spray nozzle position at lower impressions plate upper surface and have the die cavity groove.Form the die cavity that supplies injection heat solidity plastic products by upper impression plate and the equipped back of lower impressions plate.Have the hole for mounting strap idol high temperature heater (HTH) at the lower impressions intralamellar part.Be provided with the heat insulation supporting seat of this device in lower impressions plate bottom.
Compare with former thermosetting injection mo(u)lding, the utlity model has following beneficial effect:
1, keeps being in low temperature in the cast gate runner zone and mould molten state, inject the purpose of no waste material handle continuously to reach thermosetting plastics.Can reduce 80～90% of material that former waste material handle wasted.
2, using this quick-setting thermosetting running channel injection moulding warm in nature can produce continuously, and productivity ratio can improve 30%.
3, warm running channel injection moulding is saved electric 30-50% than former technology injection moulding.
4,, thereby make ILS because (about the 80 ℃) work at low temperatures of mould manifold is little to thermosetting plastics machine and hydraulic system heat conduction influence again in the mould inside heating.
5, reduce because of handling the environmental pollution that the waste material handle causes, reduce labour intensity, increase handling safety.
6, thermosetting running channel injection mo(u)lding warm in nature adapts to the moulding that has a large capacity and a wide range, as auto manufacturing, electric appliance and electronic industry, building industry, instrument industry, household electrical appliance, the moulding that extinguisher and national defense industry etc. are produced in enormous quantities.
7, the mould structure that has fast quick-detach waste material handle.When stopping class or disorderly closedown must dismantle in the manifold unique waste material handle the time, needn't from lathe, disassemble unitary mould, only need mobile upper impression plate, and it can be hung on the injection machine slide bar, the unique waste material handle in the promptly detachable mould.
