Description
Technical field
The utility model belongs to aerogel heat-proof cover, is specifically related to the heat shield that a kind of security is high.
Background technology
Injection machine utilizes mould for plastics to make the main former of the plastic products of various shape thermoplastic or thermosetting material.Injection machine is made up of injecting systems, Clamping System, Hydraulic Power Transmission System, electric control system, lubricating system, heating and cooling system, safety monitoring system etc. usually.Heating collar is parts important in heating system, and heating collar heats barrel and die head, and injection molding, stretching again after plastic raw materials melting is plastified, extrusion molding is product.The process that current existing heating collar is running has following defect:
1, heat loss is large: current existing heating collar major part, for being exposed in air, making the heat major part outside heating collar be lost in air, causes the waste of electric energy;
2, workshop condition temperature rises: because heat scatters and disappears in a large number, ambient temperature raises, especially summer is very large on production environment impact, the temperature of heating collar outer surface can reach about 200 DEG C, work on the spot temperature has even exceeded 45 DEG C, some enterprise has to adopt air-conditioning to reduce temperature, and this causes again the secondary of the energy to waste;
3, service life is short: due to scattering and disappearing of heat, heating collar needs constantly to heat operation, and the frequency of utilization of heating collar is large, causes heating collar short for service life;
4, because temperature in workshop is high, lubricant temperature rise, greatly shortens oil sealing, oil pump service life, occurs leakage of oil and pressure transient phenomenon.
5, there is potential safety hazard: because the temperature of heating collar outer surface can reach about 200 DEG C, operating personnel are very easy to burn and scald etc., there is very large potential safety hazard, bring on health uncomfortable to operator, bring loss economically to enterprise.
In order to solve the above problems, those skilled in the art is provided with heat shield in the outside of barrel heating collar, if but heat shield in the case of damages, if operating personnel can not identify in time, except increasing except power consumption, also easier operating personnel to be damaged.
Injection machine is in heating process in addition, can produce a large amount of carbon dioxide, contaminated environment.
Screw rod is the vitals of injection machine.Screw rod is located in barrel, carries, compacting, fusing, stir and exert pressure the material in barrel.All these has been come by the rotation of screw rod in barrel.The heating collar that the fusing of material is provided with by injection machine connects realization, and the course of work of heating collar is when screw rod rotates, and plastics are for machine tube inner wall, screw channel bottom surface, spiral shell rib pressure surface and all can produce friction and mutually move between plastics and plastics.
