Abstract
The invention relates to the technical field of die casting, and discloses a horizontal hopper die casting machine. The horizontal hopper die casting machine comprises a fixed die, a movable die and a pressure chamber. The fixed die and the movable die are closed and attached to form a die casting die cavity. The pressure chamber is located at one end of the movable die. The movable die is provided with a pouring gate. The two ends of the pouring gate are communicated with the pressure chamber and the die cavity respectively. The upper end of the pressure chamber is connected with a hopper. A hopper mouth is communicated with the pressure chamber. The hopper is filled with metal fusion liquid. A pressure head is arranged in the pressure chamber, and the pressure head is arranged in the pressure chamber in a sleeved manner. By means of the scheme, the hopper is arranged, and the pressure head is used for controlling falling down of the metal fusion liquid. The time for die casting of single castings becomes short, the production efficiency is improved, meanwhile, labor is omitted, and labor resources are saved.
Description
Technical field
The present invention relates to compression casting technical field.
Background technology
Die casting (English: to be diecasting) a kind of metal casting technique, be characterized in utilizing mold cavity to apply high pressure to the metal melted.Mould normally processes with the alloy that intensity is higher, a bit similar injection mo(u)lding of this process.Most of die casting foundry goods is all nonferrous, such as zinc, copper, aluminium, magnesium, lead, tin and terne metal and their alloy.According to the difference of die casting type, need to use cold-chamber die casting machine or hot chamber machine.The type that die casting machine mainly can be divided into hot chamber machine and cold-chamber die casting machine two kinds different, difference is that they can bear great strength, and typical pressure limit is between 400 to 4000 kilograms.Wherein can adopt cold chamber die casting when die casting cannot be used for the metal of hot chamber diecasting technique, comprise the kirsite that aluminium, magnesium, copper and aluminum content are higher.In such a process, need first Metal Melting to be melted in one independently crucible.Then the motlten metal of some is transferred to one not by the injection room of heating or injection nozzle.By hydraulic pressure or mechanical pressure, these metals are injected among mould.Cold-chamber die casting machine also has vertical and horizontal dividing, and vertical die-casting machine is generally small machines, and horizontal plunger die casting machine then has various model.
Because cold-chamber die casting machine needs motlten metal to shift into cold house, the maximum shortcoming of this technique is that circulation timei is very long.And main dependence is poured into a mould manually, wastes manpower and time, also has larger danger simultaneously.
Summary of the invention
The invention is intended to provide a kind of die casting short for circulation timei, the simple funnel horizontal plunger die casting machine of structure, to replace artificial cast, improve safety and the automaticity of the process of production.
Funnel horizontal plunger die casting machine in this programme, comprise cover half, dynamic model, pressure chamber, described fixed half and moving half closes the die cavity that laminating forms die casting, and pressure chamber is positioned at one end of dynamic model, and dynamic model is provided with running channel, the two ends of this running channel are connected with pressure chamber, die cavity respectively, the upper end of described pressure chamber is connected with funnel, and bell mouth is communicated with pressure chamber, is filled with point molten metal in described funnel, be provided with pressure head in pressure chamber, be placed in pressure chamber in described pressure head.
Beneficial effect: before die casting, the position of pressure head is positioned at lural rear end, Metal Melting solution in funnel is due to gravity, enter in pressure chamber by bell mouth, ram movement, extrusion metal fused solution, point molten metal enters in die cavity by running channel, and pressure head continues to promote, block bell mouth, point molten metal in funnel cannot enter pressure chamber, and pressure head continues to promote point molten metal and is full of die cavity, and curing molding under pressure, carry out press casting procedure, after die casting completes, take off dynamic model, foundry goods is taken out.Adopting the program, by arranging funnel, and being controlled the whereabouts of molten metal bath by pressure head, die casting shortened when a foundry goods time, and production efficiency improves, and eliminated artificial simultaneously, had saved labo r resources.
Further, described dynamic model outer end is fixedly connected with slide bar, and sliding bar is connected to fixing frame, and dynamic model can, in the enterprising line slip of frame, make taking-up foundry goods convenient.
Further, the outer surface of described funnel is also connected with heater, can the carrying out that the molten metal bath in funnel continues be heated.
Further, the outer surface of described funnel is provided with heat-insulation layer, to ensure the state of molten metal bath.
Further, one end of described dynamic model is connected with handle, is convenient to pull, and carries out die sinking pickup.
Accompanying drawing explanation
Fig. 1 is the structural representation of funnel horizontal plunger die casting machine embodiment of the present invention.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: pressure head 1, pressure chamber 11, running channel 12, funnel 2, bell mouth 21, heat-insulation layer 22, heater 23, cover half 3, dynamic model 4, handle 41, slide bar 42, frame 5.
Embodiment is substantially as shown in Figure 1:
Funnel horizontal plunger die casting machine in this programme, comprise cover half 3, dynamic model 4, pressure chamber 11, cover half 3 and the closed laminating of dynamic model 4 form the die cavity of die casting, pressure chamber 11 is positioned at one end of dynamic model 4, dynamic model 4 has running channel 12, and the two ends of this running channel 12 are connected with pressure chamber 11, die cavity respectively, the upper end of pressure chamber 11 is connected with funnel 2, bell mouth 21 is communicated with pressure chamber 11, is filled with point molten metal in funnel 2, and pressure chamber 11 inner sleeve has pressure head 1.
One end of pressure head 1 is connected by with hydraulic cylinder, and control the feeding of pressure head 1, the time of the amount of feeding of pressure head 1 should strictly control, and guarantees that the folding of bell mouth 21 puts in place, and ensures that point molten metal fully enters pressure chamber 11; During die casting simultaneously, ensure that pressure head 1 thoroughly closes bell mouth 21.
The outer surface of funnel 2 is symmetrically installed with two heaters 2, heater 2 adopts electrical heating, can heat the carrying out that the molten metal bath in funnel 2 continues.The outer surface of funnel 2 is bonded with heat-insulation layer 22, this heat-insulation layer 22 adopts polystyrene foam plastics or polyurethane foam plastics, and this material heat resistance is good, to ensure the state of molten metal bath.
