Abstract
The invention belongs to the technical field of mold processing, and in particular relates to a mold constant-temperature cooling system. The mold constant-temperature cooling system comprises a liquid storage tank which is used for storing water or other heat conducting liquids, wherein a liquid outlet of the liquid storage tank is connected with a liquid inlet of a mold cooling system; a liquid inlet of the liquid storage tank is connected with a liquid outlet of a cooling device through a pipeline; a liquid inlet of the cooling device is connected with a liquid outlet of a circulating pump through a pipeline; a liquid inlet of the circulating pump is connected with a liquid outlet of the mold cooling system through a pipeline; a temperature sensor is arranged in the liquid storage tank; the temperature sensor and the cooling device are electrically connected with a programmable logic controller (PLC); the PLC controls the starting and stopping of the cooling device according to a signal of the temperature sensor; and heat-preserving layers wrap the outer surfaces of the pipelines. The mold constant-temperature cooling system is applicable to the field of various types of casting processing, effectively improves the quality of a cooled plastic piece, and saves the water.
Description
Technical field
The invention belongs to the mold machining technology field, especially a kind of mould constant temperature cooling system.
Background technology
Also be provided with cooling water channel in the existing mould, cooling water channel generally is connected with running water pipe.After plastic injection moulding in the mould is finished, by being located at the quick cooling and shaping of cooling water channel in the mould.But because changes of seasons, variation of temperature, the water temperature in the running water pipe also has certain temperature difference, like this, can cause certain difference for the time of the plastic cooling and shaping in the mould.And mould is installed on the forcing press, and the stroke of forcing press generally is definite value, and regulating and changing all needs to increase cost.And in cooling procedure, the difference of chilling temperature also can cause the difference of plastic part quality.In addition, flow out the cooling water of mould generally all directly discharged to sewer, waste very much the water source.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of mould constant temperature cooling system, can improve the quality of plastic, and can using water wisely.
In order to solve the problems of the technologies described above, the present invention includes for the fluid reservoir that stores water or other heat-conducting liquids, the liquid outlet of described fluid reservoir is connected with the inlet of mold cooling system by pipeline, the inlet of described fluid reservoir is connected with the liquid outlet of cooling device by pipeline, the inlet of described cooling device is connected with the liquid outlet of circulating pump by pipeline, the inlet of described circulating pump is connected with the liquid outlet of mold cooling system by pipeline, also be provided with temperature sensor in the described fluid reservoir, described temperature sensor and cooling device also are electrically connected with the PLC controller, and described PLC controller is according to the start and stop of the signal controlling cooling device of temperature sensor.
Further, described pipeline appearance is enclosed with heat-insulation layer.
The present invention can make the current constant temperature in the cooling water channel in the mould, can immobilize the cool time of plastic like this, and the cooled surface flatness of plastic etc. are all guaranteed.Also using water wisely of the circulatory system simultaneously.
Description of drawings
Accompanying drawing 1 is structural representation of the present invention.
The specific embodiment
The embodiment that the present invention is cited; just be used for helping to understand the present invention; should not be construed as the restriction to protection domain of the present invention; for those skilled in the art; under the prerequisite that does not break away from inventive concept; can also improve and modify the present invention, these improvement and modification also fall in the scope of claim protection of the present invention.
As shown in Figure 1, the present invention includes for the fluid reservoir 1 that stores water or other heat-conducting liquids, the liquid outlet of described fluid reservoir 1 is connected with the inlet of mold cooling system by pipeline, the inlet of described fluid reservoir 1 is connected by the liquid outlet of pipeline with cooling device 2, the inlet of described cooling device 2 is connected by the liquid outlet of pipeline with circulating pump 3, the inlet of described circulating pump 3 is connected with the liquid outlet of mold cooling system by pipeline, also be provided with temperature sensor 11 in the described fluid reservoir 1, described temperature sensor 11 and cooling device 2 also are electrically connected with PLC controller 4, and described PLC controller 4 is according to the start and stop of the signal controlling cooling device 2 of temperature sensor 11.
Further, described pipeline appearance is enclosed with heat-insulation layer.
This circulatory system can be dismantled, and is applicable to multiple kinds of molds.In the time of mold exchange more, as long as water inlet and the delivery port of constant temperature cooling system of the present invention from the cooling water channel of mould disassembled, be connected with new mould and get final product.
The course of work is: current pressurization through circulating pump in circulation provides power, enter cooling device, current are after apparatus for supercooling, enter fluid reservoir, water temperature in the temperature inductor induction fluid reservoir in the fluid reservoir, signal is passed to the PLC controller, PLC controller analytic signal, control refrigerating plant startup and stop.Current flow to cooling water channel from fluid reservoir, absorb heat in cooling water channel, and the plastic in the mould is cooled off, and flow out from delivery port afterwards, enter circulating pump by water-supply-pipe.Circulation successively.
Using method is mould to be installed in forcing press, perhaps above the injection machine.After debugging is finished, the connection of transfusion room and connecting pipe, circulating pump, cooling device is installed.After the installation, circulating pump, refrigerating plant can be connected power supply.The water route begins circulation.The signal that is obtained from temperature sensor by the PLC controller is controlled refrigerating plant and is freezed.
