Description
Technical field
The invention belongs to accessory die casting equipment field, more particularly to a kind of household electrical appliances accessory casting device.
Background technology
The assembling of refrigerator needs more accessory, and accessory includes refrigerator shell, hinge, fin, mounting bracket, piston, turned
Axle evaporator shell etc., and the making of these accessories can be completed using a kind of horizontal plunger die casting machine, due to horizontal plunger die casting machine one
As using hydraulic jack as actuating unit, when in use, the die sinking of horizontal plunger die casting machine and matched moulds can produce certain vibration, such as
Vibration can not be preferably eliminated, the die casting precision and service efficiency of die casting machine can be influenceed, it is unqualified in turn result in product quality.
In order to solve problem above, Chinese Patent Application No. is 201620659172.2 utility model patent, is disclosed
A kind of horizontal plunger die casting machine, including die casting machine body, clamping and control panel, die casting machine body are provided with die casting groove, close
Mold mechanism is in die casting groove, and control panel is located at the front end of die casting machine body, and it also includes support column, base and damping machine
Structure, support column are located at the lower end of die casting machine body, and base is provided with mounting groove, and damping is located at the lower end of support column and installation
Between groove.Above when in use, die casting is carried out by the clamping of horizontal plunger die casting machine, and can be produced in press casting procedure certain
Vibration, because the design of damping can be to vibrating into row buffering and elimination, and then improve die casting precision.
Above scheme solves deficiency of the prior art by the setting of damping, but above scheme also exist with
Lower shortcoming：During die casting, in order that the die-casting material obtained in the die cavity of mould is enough, die-casting material is often set to be overflowed at sprue gate,
But after the accessory cooling of die casting, the die-casting material overflowed at sprue gate can also be molded into the unnecessary part of accessory, it is necessary to operate
Personnel cut to accessory, add operator's step, reduce the producing efficiency of accessory.
The content of the invention
The invention is intended to the household electrical appliances accessory casting for providing a kind of cut-off die-casting material, reducing operating procedure and improving producing efficiency
Make device.
Household electrical appliances accessory casting device in this programme, including frame, are provided with die casting cylinder and mould in frame, on die casting cylinder
Discharge nozzle is communicated with, the outlet of discharge nozzle leaves cutting towards the import of mould between the outlet of discharge nozzle and the import of mould
Mouthful, die casting block is slidably connected in die casting cylinder, push rod is fixedly connected with die casting block, piston cylinder, pusher slide are provided with frame
It is dynamic to be connected in piston cylinder, be connected with the first spring between push rod and piston cylinder, side of the piston cylinder away from push rod be communicated with into
Tracheae, be fixed with air pump in frame, valve be provided with air inlet pipe, be additionally provided with frame opened for valve opening delay it is big
Time-delay mechanism, the cutter for cutting the die-casting material in cutting mouth are slidably connected in frame, are connected between cutter and frame
Second spring is connected to, the push rod for promoting cutter is fixed with push rod.
The technical principle of this programme is：When initial, valve has certain aperture, and booster air pump, air pump is into air inlet pipe
Ventilation, gas are ventilated by air inlet pipe into piston cylinder, and gas push push rod moves into die casting cylinder, and push rod will promote die casting block
Die-casting material is promoted to be moved into discharge nozzle, in the die cavity that die-casting material will enter mould from discharge nozzle；While booster air pump,
Start-up study mechanism, slowly pressed after die-casting material moves a period of time into die cavity after die casting block, time-delay mechanism is by valve
Aperture is opened greatly, and the aperture of valve is opened greatly, the gas flow moment increase in air inlet pipe, the gas being flowed into from air inlet pipe in piston cylinder
Body flow moment increases, the air pressure moment increase in piston cylinder, and presses push rod and slided with quickly speed into die casting cylinder, presses
Ingot bar will press die-casting material with bigger pressure and quickly be injected into the die cavity of mould, the increase of pressure so that the mould of mould
Intracavitary is full of enough die-casting materials；While push rod promotes die casting block, push rod drives push rod to go to slide together, and push rod will hit
Cutter, cutter are moved to close to the direction of die casting cylinder, and cutter will be cut to the die-casting material in cutting mouth, and will be gone out
Die-casting material is cut off in expects pipe, also causes the die-casting material between die casting mouth and discharge nozzle outlet to cut, and after accessory shaping, is poured
Unnecessary part will not be produced at geat, the step of decreasing cutting, improves producing efficiency.
Compared with prior art, this programme has the beneficial effect that：This programme passes through die casting block, time-delay mechanism and cutter etc.
Setting, while die casting, the die-casting material in the die-casting material and mould in die casting cylinder can be cut off, and mould can be avoided
Sprue gate produce unnecessary die-casting material, after accessory shaping, unnecessary part will not be produced at sprue gate, reduces operation
The step of personnel cut to redundance, so as to improve producing efficiency.
Further, time-delay mechanism includes branch pipe of the connection in air inlet pipe, and branch pipe is between piston cylinder and valve, branch pipe
Air bag is communicated with, side of the air bag away from branch pipe is communicated with communicating pipe, and sequencing valve is provided with communicating pipe, drive is provided with frame
Dynamic cylinder, is communicated with driving cylinder communicating pipe, drives in cylinder and slidably connects rack, gear, tooth are fixedly connected with the valve rod of valve
Bar is engaged with gear, and the 3rd spring is connected between rack and frame, is provided with the frame of air bag side big program control for opening
The button of valve opening, air bag are used to offset with button.While air pump is opened, to being ventilated in branch pipe, gas leads to air pump
Crossing branch pipe will be flowed into air bag, and the volume of air bag will increase, and when air bag volume, which increases to, to be offseted with button, sequencing valve will
Opened, the gas in air bag will be entered in driving tube by communicating pipe, and the air pressure increase of driving tube, gas will promote tooth
Bar moves, and rack will drive pinion rotation, and gear rotates the valve rod with movable valve, and the aperture of valve will increase, so as to real
The function that big valve opening is opened in delay is showed.
Further, valve is gate valve.Facilitate the control to valve opening.
Further, air bleeding valve is communicated with air bag.After the completion of die casting, air bleeding valve is opened, the gas in air bag will discharge,
His gas in piston cylinder and driving cylinder, which will arrive, to be flowed into air bag, and is discharged from air bleeding valve, completes the reset of whole device, right
The operation of next die casting is prepared.
Further, air pump is air blower.The setting of air blower, facilitates and piston cylinder and air bag is inflated.
Further, it is communicated with feed pipe on die casting cylinder.Die casting cylinder is fed by feed pipe.
