The hot-forming system of processing of a kind of thin-film material
Technical field
The utility model belongs to heat pressing forming machines technical field, is specifically related to the hot-forming system of processing of a kind of thin-film material.
Background technology
Known, the thin-film material that manufacturing has shape and Asperity model is generally formed with plastic mould injection moulding, but during injection moulding, the water inlet of plastic mould often has burr, and burr removing is wasting manpower and material resources not only, and very large to the quality influence of thin-film material.
Along with the fast development of industrial technology, in thin-film material production, process, heat pressing forming machines plays irreplaceable effect.Hot-formingly become a kind of simple, general method in film processed material, raw material are put in mould, then apply pressure with shaping after mainly utilizing heating processing mold by it.According to the raw-material difference selected, forming temperature and pressure all have certain scope, restriction, and compared with other processing method, hot-forming have the advantages such as mould is cheap, finished product thickness is even.
But, mold preheating temperature and the temperature retention time of existing heat pressing forming machines still mainly adopt manual type, namely preheating time and the temperature retention time of mould is adjusted by range estimation, this mode directly cause product percent of pass and production efficiency low, because product quality did not affect in conjunction with the temperature required many factors such as to carry out of preheating by variation of ambient temperature, heating plate heat radiation power unstable, the artificial adjustment preheating time of staying, affect forming quality of products; In addition, in the bed die group that heat pressing forming machines uses, lower bolster and die shoe are one, thin-film material is adding man-hour, and what thin-film material is positioned over bed die group gets stuck in groove, because thin-film material material is frivolous, air-flow can be produced downwards when mold group is exerted pressure, then thin-film material can be made in the phenomenon occurring in groove rocking that gets stuck, cause shaping after product size bad, thus cause whole work efficiency and product quality low.Therefore, we are in the urgent need to the hot-forming system of processing of a kind of new thin-film material with accurate control temperature, and uniform stressed, realizes the high-quality thin-film material of processing.
Summary of the invention
The purpose of this utility model is for above-mentioned Problems existing and deficiency, the utility model proposes a kind of simple to operate, dismantle easy, reduce costs with accurate control temperature and uniform stressed, improve the hot-forming system of processing of thin-film material of film product quality.
For achieving the above object, the utility model have employed following technical scheme:
The hot-forming system of processing of a kind of thin-film material, wherein: include even material pressing device and device for monitoring temperature, even material pressing device comprises mold group and bed die group; Described mold group comprises cope match-plate pattern, upper bolster and upper bolster backing plate, and is fixedly mounted on heat pressing forming machines upper part of the frame from top to bottom; Described bed die group comprises slip drift, lower bolster, die shoe, spring and die shoe backing plate, and be fixedly mounted on heat pressing forming machines support bottom from top to bottom, described slip drift is located in lower bolster, and described spring is located between die shoe backing plate and slip drift; Described device for monitoring temperature comprises the infrared sensor being located at guide pillar, the heating plate be located on described cope match-plate pattern, lower bolster and slip drift, establishes heating tube on hot plate; Described die shoe backing plate is provided with pressure inductor; Described infrared sensor is connected with PLC with pressure inductor, and described PLC is connected with power supply, display screen and heating tube respectively.
Further, power switch is provided with between described PLC and power supply.
Further, described slip drift is positioned over the draw-in groove place offered in described lower bolster, makes it be stabilized on lower bolster by the effect of support spring power.
Further, the corresponding lower bolster in position of described infrared sensor is arranged, position when the corresponding cope match-plate pattern in position of infrared sensor does not work.
Further, the upper end of described lower bolster offers the groove that gets stuck.
The beneficial effects of the utility model:
1. after thin-film material steadily being pushed down by the power effect of counterdie support spring and the effect of cope match-plate pattern pressure in hot-forming process, carry out hot-forming processing, effective guarantee product uniform force when shaping, product bending size is good, reduce the appearance of defective products, thus promote the quality of hot-forming rear product.
2. pass through the temperature conditions of infrared sensor Real-time Collection mould and sheet material, and this temperature conditions is passed to PLC in real time show, PLC is according to the temperature information received, and control the break-make of power switch, realize temperature Real-Time Monitoring and the control of mould, thus promote the quality of hot-forming rear product.
