The utility model discloses a temperature of preheating the mould die cavity in advance can accurate control die cavity temperature.
Description
Technical field
The utility model relates to machine die forming field, is specially a kind of detection system warm in advance for mould.
Background technology
In the production process of mould product injection moulding, in order to guarantee quality and the requirement for delivery of product, original injection moulding production technique is the mould-cavity temperature by slowly improving mould in production, thus the Conditions Temperature required for reaching moulding process, but the product produced before Conditions Temperature required for reaching moulding process most of may be defective products, so not only a large amount of waste starting material, the temperature in mould inner mould chamber is also wayward simultaneously, the time of payment is also extended by this process greatly, the risk delivered goods and break may be caused, inestimable loss is brought to enterprise.
Summary of the invention
The purpose of this utility model is to overcome the defect of prior art, it provides the temperature of a kind of preheated mold die cavity in advance, can accurately control the detection system that the mould of mould-cavity temperature is warm in advance.
The utility model is achieved through the following technical solutions:
For the detection system that mould is warm in advance, it comprises pressure water source pump and mould temperature well heater, mould cavity, water inlet pipe, return water pipe; Described pressure water source pump and mould temperature well heater are connected with mould cavity by water inlet pipe; Described mould cavity is connected with pressure water source pump and mould temperature well heater by return water pipe; Described return water pipe is provided with temperature sensor; Described temperature sensor is connected with PLC programmer; Described PLC programmer is connected with injection moulding machine computer.
After adopting above structure, a kind of detection system warm in advance for mould of the present utility model, compared with prior art has the following advantages:
Before products production, by pressure water source pump and mould temperature well heater, pre-warm water is heated, pre-warm water (temperature is higher than the Conditions Temperature required for reaching moulding process) after heating is injected in die cavity by water inlet pipe, and the pre-warm water in die cavity returns to pressure water source pump and mould temperature well heater by return water pipe. Whether the pre-warm water detected in die cavity by set temperature inductor block on return water pipe and pressure sensitive device rises to the temperature value needed for producing shaped standard conditions, during Conditions Temperature required for reaching moulding process, started working by injection moulding machine launch computer injection moulding machine, during Conditions Temperature required for not reaching moulding process, then can not start injection moulding machine. Greatly shorten time production cycle by the temperature of preheated mold die cavity in advance like this, reduce because being produced the bad of product when temperature or pressure condition do not meet. Can greatly improve by the temperature reliability in monitoring die cavity at any time simultaneously.
Improve as one of the present utility model, water inlet pipe is installed filtering net prevent from entering mould cavity by the impurity in the pre-warm water in pressure water source pump and mould temperature well heater and incrustation scale, cause and drawing of mould cavity is hindered, thus affect the quality of production of product in die cavity.
Improve as one of the present utility model, setting pressure sensor on return water pipe, the change of backwater inner pipe water pressure can be detected by pressure sensitive device, the numerical value that pressure transmitter detects is reflected to PLC programmer (including display screen) and judges whether return water pipe or mould cavity the problem such as pressure instability and water line block occur by the change of pressure value.
Improving as one of the present utility model, described PLC programmer comprises PLC programmer display screen, and the data of the pressure transmitter received and temperature sensor can be shown on a display screen by PLC programmer display screen.

Wherein: 1, pressure water source pump and mould temperature well heater, 2, mould cavity, 3, water inlet pipe, 3.1, filtering net, 4, return water pipe, 5, pressure transmitter, 6, temperature sensor, 7, PLC programmer, 8, injection moulding machine computer
Embodiment:
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1 for the detection system that mould is warm in advance, it comprises, mould cavity 2, water inlet pipe 3, return water pipe 4; Described pressure water source pump and mould temperature well heater 1 are connected with mould cavity 2 by water inlet pipe 3; Described mould cavity 2 is connected with pressure water source pump and mould temperature well heater 1 by return water pipe 4; Described return water pipe is provided with temperature sensor 6; Described temperature sensor 6 is connected with PLC programmer 7; Described PLC programmer 7 is connected with injection moulding machine computer 8.
Before products production, by pressure water source pump and mould temperature well heater 1, pre-warm water is heated, pre-warm water after heating (temperature will far above the Conditions Temperature required for reaching moulding process) pushes away into the mould cavity 2 being pushed into pre-manufactured by water inlet pipe 3, allow the temperature of mould cavity 2 of pre-manufactured rise to the temperature required by processing condition and can produce startup, now by the water temperature of monitoring return water pipe 4. This water temperature described is with the water temperature equaling die cavity. Such as water inlet pipe 2 temperature is 100 DEG C, enters after mould cavity 2 exchanges and enters return water pipe 4, at this moment water temperature only 80 DEG C, these 80 DEG C of temperature also representing mould cavity 2. Its pressure and temperature is detected out by pressure transmitter 5 now in parallel in return water pipe 4 and temperature sensor 6, and it is sent in PLC programmer 7 with electrical signal, the processing condition of injection moulding to injection moulding machine computer, are carried out analysis by injection moulding machine computer and could produce startup by output switch amount signal by PLC. When mould-cavity temperature reaches processing condition institute palpus temperature, injection moulding machine computer just can start production sequence.
Water inlet pipe is installed filtering net 3.1 prevent from entering mould cavity by the impurity in the pre-warm water in pressure water source pump and mould temperature well heater and incrustation scale, cause and drawing of mould cavity is hindered, thus affect the quality of production of product in die cavity.
Setting pressure sensor on return water pipe, the change of backwater inner pipe water pressure can be detected by pressure sensitive device, the numerical value that pressure transmitter detects is reflected to PLC programmer (including display screen) and judges whether return water pipe or mould cavity the problem such as pressure instability and water line block occur by the change of pressure value.
Described PLC programmer comprises PLC programmer display screen, and the data of the pressure transmitter received and temperature sensor can be shown on a display screen by PLC programmer display screen.
Whole process does not need manpower or extra power source to get involved, it is possible to the temperature in monitoring die cavity at any time, and save energy and labour intensity are easy and simple to handle, reliability height. This mould in advance temperature detection system also reduce the bad product because producing when temperature or pressure condition do not meet greatly.
