Abstract
The utility model discloses a low-pressure pouring locking device which comprises a platen and locking devices. The locking devices are arranged at four corners of the platen and used for tightly locking a sand box between the platen and a cover plate of a low-pressure pouring furnace. The platen is welded on a steel plate between two rods of U-steel. Each locking device comprises a high-strength chain which is connected at one end of U-steel through a pin shaft, a turnbuckle bolt and an eyebolt. One end of the turnbuckle bolt is connected with the other end of the chain. The eyebolt is connected with the other end of the turnbuckle bolt and fixed on the cover plate of the low-pressure pouring furnace. The low-pressure pouring locking device is simple in manufacture, low in cost, suitable for low-pressure pouring locking of products with sand boxes which are different in terms of length, height and width. No special tools are needed. Locking time is greatly saved. Production efficiency is improved. Rate of finished poured products is improved. The steel plate welded on the U-steel is used for preventing molten aluminum from rushing out of the top of the sand box and injuring people. Safety coefficients are improved.
Description
Technical field
The utility model relates to a kind of low-pressure casting locking device.
Background technology
Along with the extensive application of aluminium casting in all trades and professions, kind was more and more in recent years, and output is more and more higher, adopt the technique of low-pressure casting more and more, the production efficiency of this low-pressure casting technique is low, and security risk is large, has just become the problem of each factory with safety coefficient so enhance productivity.Especially how the sandbox that differs for the size of frequent replacing, quick locking sandbox how reduces the probability that runs aluminium liquid between sandbox and the low-pressure casting stove cover plate, has improved casting yield, is an individual problem demanding prompt solution.Existing method all is that the sandbox that corresponds to different size is prepared to overpay locking device, so just can't realize quick-replaceable and the locking of quick sandbox, affects operating efficiency.
Summary of the invention
The utility model purpose is the defective for the cast locking tool, provides a kind of production efficiency high, adapts to wide, casting yield height, the locking device device that operating personnel's safety coefficient is large.
The utility model adopts following technical scheme for achieving the above object:
A kind of low-pressure casting locking device is characterized in that: it comprises pressing plate and locking device; Described locking device is arranged on four jiaos of described pressing plate, by four jiaos locking devices sandbox is locked between pressing plate and the low-pressure casting stove cover plate tightly.
It is further characterized in that: described pressing plate is to be welded on two steel plates between the channel-section steel, described locking device comprise the high-test chain that is connected to channel-section steel one end by bearing pin with is connected that end is connected with the described chain other end spend blue bolt and be fixed on the low-pressure casting stove cover plate with the lifting bolt of spending the blue bolt other end to be connected.
The utility model is made simple, cost is lower, be applicable to the locking of the low-pressure casting of sandbox length/width/product that high size differs, do not need special instrument, continuous two product sandbox height dimensions are differed larger, change first the link position of bearing pin and high-test chain, blue bolt is spent in locking again, lock sandbox than in the past independent with screw rod like this, greatly saved the locking time, improved production efficiency; Reduce the probability that runs aluminium liquid between sandbox and the low-pressure casting stove cover plate, improved casting yield; Be welded in steel plate on the channel-section steel and prevented that aluminium liquid from going out the cope top and the risk of hurting sb.'s feelings has improved safety coefficient.
Description of drawings
Fig. 1 is the utility model schematic diagram.
The specific embodiment
A kind of low-pressure casting locking device as shown in Figure 1, it comprises pressing plate 1 and locking device; Described locking device is arranged on four jiaos of described pressing plate 1, by four jiaos locking devices sandbox 3 is locked between pressing plate 1 and the low-pressure casting stove cover plate 2 tightly.
Described pressing plate 1 is for being welded on two steel plates between the channel-section steel, described locking device comprise the high-test chain 5 that is connected to channel-section steel one end by bearing pin 4 with is connected that end is connected with the described chain other end spend blue bolt 6 and be fixed on the low-pressure casting stove cover plate 2 with the lifting bolt 7 of spending blue bolt 6 other ends to be connected.
If two product sandbox height dimensions differ larger during use, change first the link position of bearing pin and high-test chain, blue bolt is spent in locking again, locks sandbox than in the past independent with screw rod like this, has greatly saved the locking time.Play the length of quick adjustment locking device by the length of adjusting chain, the diagonal angle blue bolt of exchange rotary flower plays quick locking, and the sandbox that pour into a mould is pressed on the stove cover plate tightly, has reduced artillery fire, has lifted the accident such as case and occur.
Claims (2)
