Detailed Description

In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. It will be apparent, however, to one skilled in the art, that the present invention may be practiced without one or more of these specific details. In other instances, well-known features have not been described in order to avoid obscuring the utility model.

In the traditional injection mold, the problem of exhaust is of great importance in the injection molding process, and the exhaust method of the injection mold adopts the mode that the exhaust groove is formed at the plastic flowing tail end of the mold at present, so that the quality problems of finished product surface conveying, bubbles and the like are caused if gas in an injection mold cavity cannot be smoothly exhausted. The pressure of the injection mold directly influences the plasticizing process of the material and the quality of the injection-molded part. The traditional die is used for detecting by arranging the pressure sensor, the high-temperature environment cannot be resisted, so that the device is damaged, and the surface quality of a finished product is defective due to the fact that the pressure sensor is only arranged and the temperature change cannot be detected at the same time, and meanwhile, the complexity of the whole structure is increased.

In order to solve the problems in the prior art, the utility model provides a pressure detectable floor drain mold, which has the following specific scheme:

as shown in fig. 1 to 2, a pressure detectable floor drain mold comprises a fixed mold 1 and a movable mold 3 to form a compression cavity, wherein the fixed mold 1 moves up and down along a telescopic cylinder 2 and is movably connected with a lower mold 5; the telescopic cylinder 2 drives the fixed die 1 to move up and down to realize compression molding, and the movable die 3 moves to take out a finished product.

One end of the detection device 4 is fixedly connected with the lower die 5, the other end of the detection device is movably connected with the movable die 3, and the middle part of the detection device 4 is connected with the exhaust hole 6. Because the moving mold 3 needs to be moved when the finished product is taken out, in order to prevent the detection device 4 from limiting the mold to work, the detection device 4 is fixed with the mold through the fastener 402, and one end of the fastener 402 is provided with a slide block which is in sliding connection with the moving mold 3, so that the moving mold 3 can be conveniently moved and the subsequent detection device 4 can be conveniently detached. All movements of moulding plastics in-process all can produce pressure, and the required pressure of control can produce the reasonable finished product of quality, and the pressure and the temperature variation condition can not observed simultaneously through pressure sensor to the tradition detects pressure to increase whole mould structure, occupy space. The detection device 4 is used for detecting the internal pressure of the mold cavity, can directly observe the internal temperature condition of the mold cavity, and effectively controls the actual pressure which can be borne by a molded part and effectively improves the quality of the molded part by increasing the temperature condition on the basis of pressure detection. The specific device structure scheme is as follows:

the detection device 4 comprises a capillary 406 fixedly connected with the exhaust hole 6, an indicator 404 fixedly connected with the tail end of the capillary 406, and an insulating member 405 fixedly arranged at a preset distance from the indicator 404. The capillary tube 406 is communicated with the exhaust hole 6, and the sealing ring 401 is arranged on the outer side of the capillary tube 406, so that the gas leakage is prevented from influencing the accuracy of the measured data. The manometer flows in along capillary 406 by gaseous follow, thereby promote the manometer in the manometer pointer and rotate, the gas flow in-process, partly easy low temperature liquefaction forms steam, influence screen definition on the manometer, insulating part 405 is the fixed setting in capillary 406 of breathing paper, when the hydrone is through breathing the micropore on the paper, its molecule constantly condenses and forms the drop of water and fix the one side at breathing paper, and under the effect of drop of water surface tension, effective separation hydrone infiltration gets into instruction table 404, and the gaseous opposite side that has owing to breathing paper can pass breathing paper without steam in instruction table 404, carry out data recovery, thereby effectively avoid influencing data reading, improve the accuracy of data.

Because the temperature determines the liquefaction degree of the gas, the water column is formed by liquefaction and condensation, the temperature condition can be intuitively sensed by the height of the water column, and the capillary 406 is fixedly connected with the indicator 404 capable of displaying the pressure value by adopting a glass material, so that the internal pressure can be accurately observed, the water vapor accumulation can be improved, and the temperature change can be observed. When the water column reaches a preset value, the device can be subjected to leakage flow, pressure relief and leakage flow protection, in order to prevent the situation that the device cannot be subjected to pressure relief and leakage flow due to the limitation of the appearance of the die, a first corner is downwards arranged along the horizontal extension of the capillary tube 406 by a preset distance, a second corner is formed by the vertical extension of the first corner by a preset distance, and the isolation piece 405 is horizontally and fixedly arranged at the second corner and is closely matched with the capillary tube 406. The air pressure flows along with the capillary tube 406, the cold glass is condensed and then condensed above the isolating piece 405 under the influence of gravity, the corner arrangement effectively ensures that the cold glass is condensed and then falls under the influence of gravity, the condensation force of water drops is improved to form a water column, so that the temperature condition can be judged according to the height of condensed liquid, and the accuracy of temperature detection is effectively improved. The water column itself tends to damage the insulator 405 in the capillary 406 by gravity and block another portion of the gas from entering the indicator 404, which affects the accuracy of the data. A valve 403 is vertically disposed above the isolation member 405 at a predetermined distance, and the valve 403 is fixedly disposed outside the capillary tube 406 to form a drainage area. When the water column reaches the predetermined value, the valve 403 is automatically opened, so that the internal temperature and pressure are effectively controlled, the effects of pressure relief and leakage and protection of the whole device are achieved, and meanwhile, the insulating piece 405 is prevented from being blocked by condensed water to influence the pressure measurement accuracy.
