A kind of new gate stick positioning sandbox for being used to cast

Technical field

Casting field is the utility model is related to, specifically a kind of new gate stick positioning sandbox for being used to cast.

Background technology

Casting is a kind of history of mankind's grasp than metal heat processing technique, about 6000 earlier, and China about exists B.C. 1700~it is first 1000 between have been enter into heyday of bronze casting, reached at a relatively high level in technique, cast It is that liquid metals is cast in the casting cavity being adapted with part shape, after its cooled and solidified, to obtain part or hair The method of base was mostly solid-state originally by casting material matter but was heated to the metal of liquid, such as：Copper, iron, aluminium, tin, lead etc., and mold Material can be sand, metal even ceramics, in response to different requirements, the method used would also vary from.

Quickly, one of its key factor is the progress of product technology to the development speed of casting, it is desirable to the various mechanical things of casting Rationality can be more preferable, while still has good machining property；Another reason is that mechanical industry is industrial such as with other in itself The development of chemical industry, instrument etc., favourable material conditions are created to foundry industry.

Among the process of sand casting, gate stick is needed to use to determine the position of cast gate when back-up sand makes sand mo(u)ld Put, present operating method is manually to hold gate stick with a hand to stand in inside sandbox, and another hand carries out back-up sand, very Dislocation occurs when upper drag box combines or gap occurs for inconvenience, many sandboxes, causes casting failure or iron Water, which overflows, produces defect ware, it is necessary to repeatedly process, and putting for upper and lower two sandboxes is also inconvenient.

Therefore a kind of voluntarily fixed gate stick is designed, upper drag box one, turnover is easy to use, and precision is high, without between Gap, sandbox invert the positioning sandbox of not sand leakage, and exactly inventor will solve the problems, such as.

Utility model content

In view of the shortcomings of the prior art, the purpose of this utility model is to provide a kind of new gate stick positioning for being used to cast Sandbox, it can realize and voluntarily fix gate stick, upper drag box one, turnover is easy to use, and precision is high, and very close to each other, sandbox is anti- Turn the function of not sand leakage.

Technical scheme is used by the utility model solves its technical problem：A kind of new gate stick for being used to cast is determined Position sandbox, it include sand block plate, sand block plate hook, rotating shaft A, drag box, steady pin, rotating shaft B, cope, cope link up with, pour Mouth rod location-plate, drag box front and rear sides end face are provided with steady pin, the drag box left end face top edge connection There is rotating shaft A, the drag box its right end face top edge is provided with rotating shaft B, the rotating shaft A connections sand block plate, before and after the sand block Both sides end face middle part is provided with sand block plate and linked up with, the rotating shaft B connections cope, among the cope front/rear end Place is provided with cope hook, and gate stick location-plate is provided with the outside of the cope.

Further, some positioning hole A, positioning hole B, the positioning hole A and positioning hole B are provided with the gate stick location-plate It is alternately arranged, and fixed adjacent positioning hole A is identical with the interval between positioning hole B, the positioning hole A and positioning hole B is coaxial Line arranges.

Further, the cope B can rotate around the shaft, and the cope hard-over is 180 °.

Further, the sand block plate A can rotate around the shaft, and the sand block plate hard-over is 270 °.

Further, the sand block plate hook length is identical with cope hook length, and the sand block plate hook length is equal to The distance of steady pin to drag box upper end-face edge set by drag box adds the thickness of sand block plate.

Further, the cope hook, sand block plate hook can be with 360 ° of rotations.

Further, the gate stick location-plate coordinates with cope for gap, and gate stick location-plate can be along cope edge It is mobile.

The beneficial effects of the utility model are：

1. the utility model by using the upper drag box of two rotating shafts connection and sand block plate, realizes sandbox and sand block plate Turnover operation, it is easy to use, save the function of accommodation space.

2. the utility model avoids misplacing, in elimination between drag box by using the hook of positioning when realizing use Gap, improve the function of castability.

3. the utility model realizes the fast positioning of gate stick, independently fixed, be applicable by using gate stick location-plate The function of various sizes of gate stick.

4. the utility model when realizing drag box back-up sand operation, avoids bottom surface leakage husky, stable sand by using sand block plate The effect of type.
