Description

Injection molding machine cooling system

Technical field

The utility model relates to the technical field of injection molding machine, especially a kind of injection molding machine cooling system.

Background technique

Injection molding machine also known as injection (mo(u)lding) machine or injector.It is that thermoplastic or thermosetting plastics are utilized plastic shaping The main molding equipment of plastic products of various shapes is made in mold.Mold temperature can rise with it in the injection molding machine course of work, It usually needs to cool down to mold by recirculated water.For the temperature requirement of mold recirculated water at 15-25 DEG C, temperature is lower, injection molding Machine production capacity is bigger.Cool down currently, commonly using an open circulating cooling system to injection molding machine.

But this mode has the following deficiencies: causes circulating effect with the time due to long-time using a circulatory system Passage, cause cooling effect to be deteriorated, and need to jack up replacement water, and due at this time without cold during replacing cooling water But, therefore the work that has to be molded stops operation, and finally reduces working efficiency.

Utility model content

A kind of raising cooling effect is provided purpose of the utility model is to solve above-mentioned the deficiencies in the prior art, is begun Guarantee cooling effect, a kind of final injection molding machine cooling system for improving working efficiency eventually.

To achieve the goals above, a kind of injection molding machine cooling system designed by the utility model, including can be with injection molding The upper die mechanism of the lower die cooperation of machine, is equipped with environment temperature sensor on upper die mechanism, further includes that two internal band temperature pass The cooling water tank of sensor and a refrigeration machine that water can be freezed, the upper die mechanism include upper cavity and with injection molding Lifting cylinder on machine is with the locating rod merged for pushing upper die mechanism mobile toward lower die structure, in the internal up and down of upper cavity Be equipped with wavy cooling tube, and the cooling tube on upper cavity top and the cooling tube of upper cavity lower part are mutually communicated, it is described on The cooling tube of die cavity lower part connects input terminal, and the cooling tube on the upper cavity top connects output end, and the input terminal is by dividing Orchestration is connect with the upper end of two cooling water tanks, and the output end connects the bottom of two cooling water tanks by connecting tube, and every The position that one cooling water tank bottom is connect with connecting tube be equipped with the first check valve, the distributor also pass through second one-way valve with The input of refrigeration machine connects, and the output of refrigeration machine is connect by third check valve with input terminal, is additionally provided on upper die mechanism cold But fan is equipped with the storage wind cabin for being placed in upper cavity side in the front end of cooling fan, is placed in being vertically connected with for wind cabin of storage The discharge pipe of die cavity top and the bottom is equipped with ice bag in storage wind cabin, and the environment temperature sensor, temperature sensor, first are unidirectionally Valve, second one-way valve, third check valve and distributor are electrically connected on the controller of upper die mechanism.The wherein control Device is the temperature for obtaining two water tanks in real time by the temperature sensor being set in two cooling water tanks, then controls distributor only Only realize a water tank job, the spare control process of another water tank.

When work, work first with any one cooling water tank, if the cooling water tank first with left side carries out Work, that of the cooling water tank connection in controller control distributor and left side at this time are connected all the way, and the water of cooling water tank, which flows into, to be divided Then orchestration flows into input terminal from distributor, then carry out cooling treatment to upper cavity by the path of cooling tube, then by defeated Outlet flows into the bottom of the cooling water tank in left side, and the first check valve of the bottom of the cooling water tank in the left side of controller control at this time is beaten It opens, so that the water of heat flows into the cooling water tank in left side, circulation so in cycles is realized the cooling to upper cavity, utilized simultaneously Cooling fan absorbs cold wind, is sent into storage wind cabin and is sent out by discharge pipe, realizes the air-cooled operation to upper cavity, finally realize water Cold and air-cooled synchronization job improves cooling effect, in addition once the temperature in the cooling water tank in left side is higher than preset value, closes immediately The channel in left and right left side is closed, opens the cooling water tank on right side at this time, water conservancy controls the cooling water of distributor and right side with controller That of case connection is connected all the way, and the water of cooling water tank flows into distributor, then flows into input terminal from distributor, then passes through cooling The path of pipe carries out cooling treatment, then the bottom of the cooling water tank by output end inflow right side to upper cavity, at this time controller The first check valve for controlling the bottom of the cooling water tank on right side is opened, so that the water of heat flows into the cooling water tank on right side, it is all in this way And the circulation renewed realizes the cooling to upper cavity, while obtaining environment temperature in real time using environment temperature sensor, works as room temperature When greater than preset value, second one-way valve is opened immediately, and then the cooling water that conveying comes is first flowed into refrigeration machine cooling by distributor Afterwards, it is then conveyed to cooling tube again, cooling effect, therefore the final summer realized due to environment in sweltering heat is carried out to upper die mechanism It when, the problem of causing the water self-temperature in cooling water tank excessively high, and lead to poor refrigerating efficiency, therefore set by above structure Meter can be realized and is used alternatingly using dual circuit and air-cooled synchronous working realizes raising refrigeration effect, while using real-time Environment temperature is obtained, when environment temperature is excessively high, cooling processing is carried out to cooling water in advance and is solved with this due to environment temperature And the problem of influencing refrigeration effect.

Further, it replaces for convenience, the storage wind cabin is equipped with opening, is hinged with cover board in opening.

Further, in order to improve heat dissipation effect, thermal insulation layer is equipped on the inside of storage wind cabin.

A kind of injection molding machine cooling system that the utility model obtains can be realized and is used alternatingly using dual circuit and air-cooled Synchronous working obtains environment temperature using real-time to realize raising refrigeration effect, when environment temperature is excessively high, in advance to cold But water carries out cooling processing and solves the problems, such as to influence refrigeration effect due to environment temperature with this.
