However, some workpieces have complex structures and have small-sized protrusions on the surfaces, cavities corresponding to the protrusions of the workpieces exist in the cavities of the die, the cavities are small in size, when raw materials are injected, the raw materials are difficult to flow to corners of the cavities, and finally produced workpieces have defects to form defective products. The residual gas in the concave cavity is easy to form bubbles on the surface of the workpiece, so that the strength of the workpiece is reduced while the appearance of the workpiece is influenced, and the service life is shortened. Secondly, the injection mold is generally provided with a gas outlet, when raw materials are injected, gas in the cavity is discharged from the gas outlet, but the amount of the raw materials entering the cavity is difficult to control, and if the amount of the raw materials entering the cavity is too small, a complete workpiece cannot be formed; if the raw materials that get into in the die cavity are too much, the raw materials flows out the die cavity from the gas outlet easily, also scalds the workman easily when causing the raw materials extravagant, causes the incident.
Disclosure of Invention
The invention aims to provide an injection mold for exhausting gas in a cavity so as to produce a high-strength part.
In order to achieve the purpose, the technical scheme of the invention is as follows: an injection mold for producing high-strength accessories comprises a rack, a lower mold, an upper mold, a closing mechanism and a water inlet mechanism, wherein the lower mold is fixed on the rack, a feed inlet is formed in the lower mold, a hydraulic cylinder is fixed on the rack and positioned above the lower mold, the upper mold is fixed on a piston rod of the hydraulic cylinder, and an air outlet is formed in the upper mold; the sealing mechanism comprises a sealing piston, a spring, a water inlet pipe, a water outlet pipe, a pressure valve and a water inlet one-way valve, the sealing piston penetrates through the side wall of the lower die and can slide along the side wall of the cavity, a cavity is arranged in the sealing piston, the water inlet one-way valve and the pressure valve are both fixed on the side wall of the cavity, and the water outlet end of the water inlet one-way valve and the water inlet end of the pressure valve are both communicated with the cavity; the water inlet mechanism comprises a water inlet cylinder, a water inlet piston, a hot water pipe, a cold water pipe and a drain pipe which are all communicated with the water inlet cylinder, the water inlet cylinder is fixed on the rack along the horizontal direction, a horizontal groove is arranged on the side wall of the water inlet cylinder along the horizontal direction, and the water inlet piston can slide along the inner wall of the water inlet cylinder and can seal the hot water pipe and the cold water pipe; one end of the water inlet pipe is communicated with the water inlet one-way valve, one end of the water outlet pipe is communicated with the cavity, the other ends of the water inlet pipe and the water outlet pipe penetrate through the water inlet piston and can be simultaneously and respectively communicated with the hot water pipe and the water outlet pipe, and the water outlet pipe can also be communicated with the cold water pipe; a cooling cavity is arranged at the periphery of the air outlet and is communicated with the liquid outlet end of the pressure valve, and a liquid discharge pipe with one end communicated with the cooling cavity is fixed on the upper die.
Before injection molding, the heat conduction oil storage device is communicated with the hot water pipe, the cold conduction oil storage device is communicated with the cold water pipe, and the water inlet piston seals the hot water pipe and the cold water pipe; the closing piston closes the cavity under the action of the spring. When the injection molding machine is used for injection molding, the hydraulic cylinder is opened firstly, the hydraulic cylinder is controlled to enable the upper die to move downwards to be abutted against the lower die, then the hydraulic cylinder is closed, raw materials are slowly injected into the cavity from the feeding hole, and gas in the cavity is discharged from the gas outlet. When the raw materials submerge the closed piston gradually, the closed piston slides towards the outside of the cavity under the pressure action of the raw materials, the spring is compressed at the moment, and the water inlet piston slides along the water inlet cylinder because the water inlet piston is fixed with the closed piston, and finally the water inlet pipe is communicated with the hot water pipe, and the water outlet pipe is communicated with the water outlet pipe. The heat conductive oil enters the cavity from the hot water pipe, then enters the drain pipe from the water outlet pipe, and is discharged from the drain pipe. The thermal conductivity oil raises the temperature of the closed piston, prevents the raw material in contact with the closed piston from being solidified and then being incapable of flowing, and further prevents the concave cavity from being full of the raw material. The sealing piston continues to slide, the hot water pipe is disconnected with the water inlet pipe, the drain pipe is disconnected with the water outlet pipe, and at the moment, the water inlet piston seals the hot water pipe and the drain pipe.
The sealing piston continues to slide to drive the water inlet piston to continue to slide, the cold water pipe is communicated with the water outlet pipe, cold heat conduction oil enters the cavity, the water inlet one-way valve is sealed at the moment, the pressure in the cavity is increased, and when the pressure in the cavity is greater than the preset value of the pressure valve, the cold heat conduction oil enters the cooling cavity from the water outlet end of the pressure valve, so that the temperature of the die around the cooling cavity is reduced. The die cavity is filled with the raw materials, when getting into the gas outlet, because the mould temperature around the cooling chamber is lower, and the aquatic in the cooling chamber is transmitted gradually to the heat in the raw materials, and the raw materials temperature that gets into the gas outlet reduces, and the raw materials solidifies gradually, and the raw materials can't continue to flow this moment, and the raw materials can not follow the discharge gate and flow, can avoid the raw materials to flow the die cavity and scald the workman.
And after the temperature of the die is reduced, opening the hydraulic cylinder, controlling the hydraulic cylinder to enable the upper die to move upwards, taking the workpiece out of the die cavity, resetting the sealing piston under the action of the spring, and enabling the water inlet piston to move along with the sealing piston to close the hot water pipe and the cold water pipe again.

And (III) finally, cold water enters the cavity, so that the temperature of the closed piston is reduced, heat in the raw material is gradually transferred to the cold water in the cavity, the raw material is made to be cooled, the raw material is prevented from leaking out of the die between the closed piston and the lower die, the raw material waste is avoided, and meanwhile, the high-temperature raw material is prevented from scalding workers to cause safety accidents.
And (IV) when the pressure in the cavity is increased, the cold heat-conducting oil in the cavity enters the cooling cavity through the pressure valve, so that the temperature of the die around the air outlet is reduced, when the material flows to the air outlet, the heat in the raw material is transferred to the heat-conducting oil in the cooling cavity, the raw material is solidified and cannot flow continuously, and the raw material cannot flow out of the discharge hole, so that the waste of the raw material and the scald of workers by the raw material are further avoided.
Preferably scheme one, as the further improvement to basic scheme, the section of thick bamboo inner wall that intakes is fixed with two stoppers, and the stopper is located into water piston both sides respectively. The stopper can avoid the piston slip volume of intaking too big, because the piston of intaking is fixed with the closed piston, so can also restrict the position of closed piston simultaneously, avoids the closed piston to deviate from the lower mould or fall into the die cavity completely.
In a second preferred embodiment, as a further improvement to the first preferred embodiment, a support plate is fixed to the frame, and the sealing piston is slidable along the support plate. The backup pad plays the supporting role to sealed piston, when sealed piston from the cavity roll-off gradually, can avoid sealed piston to take place the slope under self action of gravity, makes the pressure between sealed piston and each lateral wall of cavity the same, avoids sealed piston to take place to warp.
