Description
Technical field
The invention belongs to accessory die casting equipment field, in particular to a kind of household electrical appliances accessory casting device.
Background technique
The assembling of refrigerator needs more accessory, and accessory includes refrigerator shell, hinge, cooling fin, mounting rack, piston, turns
Axis evaporator shell etc., and a kind of horizontal plunger die casting machine can be used to complete, due to horizontal plunger die casting machine one in the production of these accessories
As using hydraulic cylinder as power mechanism, when in use, the die sinking and molding of horizontal plunger die casting machine can generate certain vibration, such as
Vibration cannot be preferably eliminated, the die casting precision and service efficiency of die casting machine is will affect, it is unqualified in turn result in product quality.
In order to solve problem above, the utility model patent that Chinese Patent Application No. is 201620659172.2, discloses
A kind of horizontal plunger die casting machine, including die casting machine ontology, clamping and control panel, die casting machine ontology are equipped with die casting groove, close
Mold mechanism is set in die casting groove, and it further includes support column, pedestal and damping machine that control panel, which is set to the front end of die casting machine ontology,
Structure, support column are set to the lower end of die casting machine ontology, and pedestal is equipped with mounting groove, and damping is set to lower end and the installation of support column
Between slot.Above when in use, die casting is carried out by the clamping of horizontal plunger die casting machine, and can be generated in press casting procedure certain
Vibration, since the design of damping can be buffered and be eliminated to vibration, so improve die casting precision.
Above scheme solves deficiency in the prior art by the setting of damping, but above scheme there is also with
Lower disadvantage: when die casting, in order to enable the die-casting material in the die cavity of mold is enough, overflowing die-casting material from sprue gate,
But after the accessory of die casting is cooling, the die-casting material overflowed at sprue gate can also be molded into the extra part of accessory, it is necessary to operate
Personnel cut accessory, increase operator's step, reduce the producing efficiency of accessory.
Summary of the invention
The invention is intended to provide the household electrical appliances accessory casting of a kind of cut-off die-casting material, reduction operating procedure and raising producing efficiency
Make device.
Household electrical appliances accessory casting device in this programme, including rack, are provided with die casting cylinder and mold in rack, on die casting cylinder
It is communicated with discharge nozzle, the outlet of discharge nozzle is towards the import of mold, and there are cuttings between the outlet of discharge nozzle and the import of mold
Mouthful, die casting block is slidably connected in die casting cylinder, push rod is fixedly connected on die casting block, piston cylinder, pusher slide are provided in rack
It is dynamic to be connected in piston cylinder, be connected with the first spring between push rod and piston cylinder, piston cylinder far from the side of push rod be communicated with into
Tracheae is fixed with air pump in rack, valve is provided in air inlet pipe, be additionally provided in rack opened for valve opening delay it is big
Time-delay mechanism slidably connects the cutter for cutting the die-casting material in cutting mouth in rack, connects between cutter and rack
It is connected to second spring, the mandril for pushing cutter is fixed on push rod.
The technical principle of this programme are as follows: 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 is moved into die casting cylinder, and push rod will push die casting block
Die-casting material is pushed to move into discharge nozzle, die-casting material will be out of, discharge nozzle enters mold die cavity；While booster air pump,
Start-up study mechanism slowly presses after die-casting material moves a period of time into die cavity after die casting block, and time-delay mechanism will be valve
Aperture is opened greatly, and the aperture of valve is opened greatly, and the gas flow moment in air inlet pipe increases, the gas being flowed into piston cylinder from air inlet pipe
Body flow moment increases, and the air pressure moment in piston cylinder increases, 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 mold, the increase of pressure, so that the mould of mold
It is intracavitary to be full of enough die-casting materials；While push rod pushes die casting block, push rod drives mandril to go to slide together, and mandril will be hit
Cutter, cutter are moved to the direction close to die casting cylinder, and cutter will cut the die-casting material in cutting mouth, and will be gone out
Die-casting material is cut off in expects pipe, but also the die-casting material between die casting mouth and discharge nozzle outlet is cut, after accessory molding, is poured
The step of extra part will not be generated at geat, decrease cutting, improve producing efficiency.
Compared with prior art, this programme has the beneficial effect that this programme by die casting block, time-delay mechanism and cutter etc.
Setting the die-casting material in the die-casting material and mold in die casting cylinder can be cut off while die casting, and can avoid mold
Sprue gate generate extra die-casting material, after accessory molding after, extra part will not be generated at sprue gate, reduces operation
The step of personnel cut redundance, to improve producing efficiency.
Further, time-delay mechanism includes the branch pipe being connected in air inlet pipe, and branch pipe is between piston cylinder and valve, branch pipe
It is communicated with air bag, air bag is communicated with communicating pipe far from the side of branch pipe, and sequencing valve is provided on communicating pipe, drive is provided in rack
Dynamic cylinder, is communicated with driving cylinder communicating pipe, drives in cylinder and slidably connects rack gear, gear, tooth are fixedly connected on the valve rod of valve
Item is engaged with gear, and third spring is connected between rack gear and rack, is provided in the rack of air bag side big program-controlled for opening
The button of valve opening, air bag with button for offseting.While opening air pump, for air pump to ventilating in branch pipe, gas is logical
Crossing branch pipe will be flowed into air bag, and the volume of air bag will will increase, and when air bag volume, which is increased to, to offset with button, sequencing valve will
It is turned on, the gas in air bag will be entered in driving tube by communicating pipe, and the air pressure of driving tube increases, and gas will push tooth
Item movement, rack gear will be rotated with moving gear, and gear rotates the valve rod with movable valve, and the aperture of valve will will increase, thus 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, exhaust valve is communicated on air bag.After the completion of die casting, exhaust valve is opened, the gas in air bag will be discharged,
His gas in piston cylinder and driving cylinder, which will arrive, to be flowed into air bag, and is discharged from exhaust valve, and the reset of whole device is completed, right
The operation of next die casting is prepared.
Further, air pump is air blower.The setting of air blower, facilitates and is inflated to piston cylinder and air bag.
Further, feed pipe is communicated on die casting cylinder.It is fed by feed pipe to die casting cylinder.
