Abstract
The invention relates to a casting mold knockout head with spinning type ejector cores. The casting mold knockout head comprises a fixing base. A lifting air cylinder is arranged on the upper surface of the fixing base. The multiple ejector cores are arranged on the lower surface of the fixing base and correspond to sand shooting holes in position. The fixing base is of a hollow structure with an inner cavity, and an air inlet pipe communicated with the inner cavity of the fixing base is arranged on the upper surface of the fixing base. The upper ends of the ejector cores are rotationally connected with installing heads through bearings, and the installing heads and the fixing base are fixedly connected. Each ejector core is of a hollow pipe structure with an air conducting channel, and a plurality of vertically-arranged jet flow holes communicated with the air conducting channel of each ejector core are formed in the side wall of each ejector core. The jet flow holes are obliquely arranged downwards relative to the center axes of the ejector cores. The lower ends of the ejector cores are closed from the ends, and spiral blades are arranged on the inner walls of the ends. The installing heads are provided with air ventilation cavities communicated with the inner cavity and the air conducting channels, and the inner diameter of the air ventilation cavities is larger than the inner diameter of the air conducting channels.
Description
Technical field
The present invention relates to casting technology field, particularly the Removal Technology of casting mould.
Background technology
At present, a lot of foundry goods all adopts Iron Mould Coated Sand, precoated sand generally adopts phenolic resins, at high operating temperatures will be defeated and dispersed, and the deadweight by sand comes off automatically from mould, but for the sand in the sand-spraying hole of swage mould, rely on deadweight not come off completely, thus also need later stage labor cleaning, therefore labour intensity is larger, production cost also increases thereupon, and manual cleanup has the phenomenon of omission unavoidably.At present, the mechanical type cleaning plant occurred, it adopts plunger tip to insert in sand-spraying hole, sand is come off from mould, this mode needs the contact internal walls of plunger tip and sand-spraying hole, when sand is more, the inner surface of squeezing action to sand-spraying hole of plunger tip causes certain damage, thus affects the normal use of mould.
Summary of the invention
The applicant, for the above-mentioned shortcoming of prior art, carries out studying and improving, and provide a kind of casting mould knockout head with self-rotary plunger tip, it adopts air blowing type mode, is come off by sand from sand-spraying hole, and its use safety, cleaning effect are good.
In order to solve the problem, the present invention adopts following scheme:
A kind of casting mould knockout head with self-rotary plunger tip, comprise holder, the upper surface of holder is provided with lift cylinder, its lower surface is provided with many plunger tips, the position of plunger tip is corresponding with the position of sand-spraying hole, described holder is the hollow-core construction with inner chamber, and its upper surface is provided with the air inlet pipe with its inner space; The upper end of plunger tip is rotationally connected by bearing and mounting head, and mounting head and holder are connected; Plunger tip is the tubular structure with air guide channel, its sidewall is with being communicated with its air guide channel and multiple jet orifices setting up and down, the inclined of the relative plunger tip of jet orifice is arranged downwards, and the lower end of plunger tip is closed by termination, and the inwall of termination is provided with helical blade; Described mounting head is with the venting cavity of communication with cavity and air guide channel, and the internal diameter of venting cavity is greater than the internal diameter of air guide channel.
Further improvement as technique scheme:
The inner of described jet orifice is with flare.
Described air inlet pipe is can the flexible bellows structure of bending.
Technique effect of the present invention is:
The present invention adopts jet-impingement mode to be come off from sand-spraying hole by sand, compares the pushing method of plunger tip, avoids the damage of sand-spraying hole inwall, ensures that knockout safely, reliably; The efficiency of rotary spray shakeout mode have also been obtained and significantly improves, and it is effective.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.

Fig. 3 is the B place partial enlarged drawing of Fig. 1.
In figure: 1, holder; 10, inner chamber; 2, lift cylinder; 3, plunger tip; 30, air guide channel; 31, jet orifice; 32, enlarging; 4, air inlet pipe; 5, mounting head; 50, venting cavity; 6, bearing; 7, termination; 8, helical blade.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further.
Embodiment one:
As shown in Figure 1, Figure 3, the casting mould knockout head of the band self-rotary plunger tip of the present embodiment, comprise holder 1, the upper surface of holder 1 is provided with lift cylinder 2, its lower surface is provided with many plunger tips 3, the position of plunger tip 3 is corresponding with the position of sand-spraying hole, and holder 1 is the hollow-core construction with inner chamber 10, and its upper surface is provided with the air inlet pipe 4 be communicated with its inner chamber 10; The upper end of plunger tip 3 is rotationally connected by bearing 6 and mounting head 5, and mounting head 5 and holder 1 are connected; Plunger tip 3 is the tubular structure with air guide channel 30, its sidewall is communicated with and multiple jet orifices 31 setting up and down with its air guide channel 30, the inclined of the relative plunger tip 3 of jet orifice 31 is arranged downwards, and the lower end of plunger tip 3 is closed by termination 7, and the inwall of termination 7 is provided with helical blade 8; Mounting head 5 is with the venting cavity 50 of communication with cavity 10 with air guide channel 30, the internal diameter of venting cavity 50 is greater than the internal diameter of air guide channel 30, and venting cavity 50 transits to air guide channel 30, overall formation one throat structure, increase the air pressure of air guide channel 30, thus increase the injection pressure of jet orifice 31.
During work, lift cylinder 2 promotes plunger tip 3 and stretches in sand-spraying hole, and air inlet pipe 4 is connected with air pump, in holder 1, import high pressure draught, and air-flow is spouting from jet orifice 31 after air guide channel 30, sprays into in sand-spraying hole, sand punching is wherein fallen; When air-flow is directed into the lower end of plunger tip 3, air-flow punching press is on the helical blade 8 of termination 7, and under the effect of airflow thrust, plunger tip 3 along with carrying out rotation in termination 7, thus realizes carrying out rotary Air blowing cleaning to sand-spraying hole.
