Description

A kind of molding aid system of injecting molding die

Technical field

This utility model relates to one can automatically carry out temperature controlled molding aid system to injecting molding die.

Background technology

In the modern life, plastic cement product is various the articles for daily use and the requisite parts of electronic equipment, along with the day by day exquisite of Product Process and the raising of consumers' aesthetic eye, requirement to plastic cement product used is more and more higher, it is embodied in the requirement that the aspects such as the outward appearance to goods, dimensional accuracy, degree of deformation are high, and in injection molding technique, mold temperature factor is the most crucial on the control of these indexs and the impact of production efficiency；When mold temperature is higher, beneficially plastic cement melt flows filling, after product surface is effective, but the highest mould temperature can cause the product demoulding, deformation is big, needs overcome longer cool time, thus reduces production efficiency；If mold temperature is on the low side, it is unfavorable for plastic cement melt flows filling, causes goods starved or surface weld mark obvious；Furthermore, the height change of mould temperature easily causes the concordance of goods and is deteriorated, and the dimensional accuracy of goods is difficult to ensure that.

At present, mould conventional mode that controls of its temperature when molding has following three kinds:

Mode one: hot alternating temperature high-light no-trace injection molding manner.It is to utilize high-temperature hot steam, High Temperature High Pressure hot water, mould local that the methods such as high-efficiency electric heating device are installed, make that some local location of mould is instantaneous reaches at a relatively high temperature, Fast Filling die cavity in the case of guarantee moulding material is the least with the mould of plastics temperature difference, and while moulding material cools down the heating agent such as steam, superheated water is transformed to cold water thus quickly reduces mold temperature, parts are made to freeze off, in order to eject.The method can obtain the manufactured goods that local location surface quality effect is the highest, belong to a kind of senior assistant formation technique, but it needs, and expensive special equipment, its technology of die manufacturing are complicated, cost is high, and it needs being used alternatingly of vapours and cold water, offer heating agent repeatedly and coolant are provided, its energy consumption is very big, is typically limited to high-end applications, it is impossible to universal.

Mode two: oil temperature machine, cooling-water machine assistant formation mode.Oil temperature machine, arranges heated oil in its mould, provides deep fat heating mould by oil temperature machine.Its temperature be applicable to injection moulding process is unable to reach the mould of suitable requirement, heats mould by oil temperature, makes mould maintain preference temperature.In injection moulding process, mold temperature can be higher than time temperature required for it, it is difficult to taking away heat, being unsuitable for mould actual temperature in injection moulding process can be higher than temperature required situation.Cooling-water machine, arranges cooling water pipe in its mould, carries Cooling Water by cooling-water machine and takes away heat, lowers the temperature to mould.It should be molded self heat be applicable to injection moulding process and cause the too high mould of mould temperature, by cooling water temperature, makes mould maintain preference temperature.It is unsuitable for being molded the heat self produced in injection moulding process and is unable to maintain that the situation of reasonable mould temperature.

Mode three: normal-temperature water circulating cooling assistant formation mode, the mould of our this kind of mode is called normal-temperature water circulating cooling assistant formation mould, such as Fig. 1.This mould structure tradition the most, with conventional, has universality routinely, energy saving economy, accounts for injection industry more than 90%.It utilizes pond water storage, through water pump force (forcing) pump to each mould oral siphon, collects return pipe, then in top, pond evaporative cooling tower lowered temperature reclamation to pond, recycle after each cooling duct.In production, mould nature intensification principle is: high temperature plastic rubber shaping material periodicities injects die cavity, through heat transfer, mold temperature constantly rises, tend towards stability during with mould conduct radiation heat radiation to balance, heating rate and the upper limit are relevant with device context and temperature environment, and general temperature can produce required mould temperature beyond normal, so that reduce mold temperature with cooling water.By the flow of Artificial Control cooling water, maintain mould to be in the operating temperature of relative constancy, thus realize the control to injection mold temperature, it is ensured that injection quality.

In above-mentioned three kinds of modes, first kind of way belongs to temperature swing type die temperance control, and i.e. in a molding cycle, temperature converts between the most high and extremely low；Second, third kind of mode is constant temperature pattern temperature control, and i.e. in each molding cycle, mold temperature remains relatively unchanged over.

Normal-temperature water circulating cooling assistant formation mode has the advantage that low cost, application are easy, is the mode generally used of injection industry, but its problem that there are two aspects: not easy-regulating and cannot heating mould.Its regulation to cooling water, usually Artificial Control is higher to the skill requirement of operator, need the operation skilled worker with rich experiences, the water yield can be adjusted faster, and constantly the dynamic of fine setting reply mould temperature changes, maintain the mould suitable temperature needed for normal production.For the person of lacking experience, the situation that mold temperature is higher or on the low side easily occurs, increase the percent defective of goods further.In addition, for just installing the mould of machine, its temperature is same as room temperature, and mold temperature is necessarily unsatisfactory for normal production requirement, generally way is through multiple injection, injecting die cavity with high temperature plastic rubber shaping material periodicities, make mold temperature edge up through heat transfer, its temperature rise needs a process, the goods percent defective that early stage produces is high, the most also can cause the embedding mould of glue part because filling compactness deficiency, and need form removal to carry out the situation keeped in repair, cause producing delay and the waste of raw material, man-hour and the energy.If the phase is with oil temperature machine preheated mold before the injection, also mould intensification problem can be solved, but mould once exceedes required temperature in subsequent production, change as can be cumbersome during water cooling mode, and its pipe interface of the equipment of two kinds of modes may not be compatible, even if identical laborious for also taking a lot of work, and in pipeline, water body also can be polluted by the fluid of residual, and feasibility is the highest.
