Description

Visual sand box

Technical Field

The utility model relates to a casting field, especially a visual sand box.

Background

When casting metal parts, a sand box is needed to be used, the traditional sand box generally comprises an upper box body, a middle box body and a lower box body, wherein the upper box body is used for compressing a sand core positioned in a cavity to prevent the sand core from floating upwards, so that the pressing force of the upper box body on the sand core is relatively large, the sand core is composed of sand, the strength is limited, the local part of the sand core is crushed under the action of pressure sometimes, and after the upper box body is buckled, an operator cannot see the condition inside the sand box and cannot judge whether the inside of the sand box body has a problem or not, so that casting waste products can be possibly caused, and economic loss is brought to enterprises. There is therefore a need for a method or apparatus that addresses the above-mentioned problems.

Disclosure of Invention

The utility model relates to a solve the above-mentioned not enough that prior art exists, provide a simple structure, design benefit can let operating personnel observe the psammitolite condition at any time to reach the visual sand box of discovering and changing damaged psammitolite purpose at any time.

The technical solution of the utility model is that: a visual sand box which is characterized in that: the sand box comprises a lower box 1, the top end of the lower box 1 is connected with a middle box 2 through a box clamp, the top end of the middle box 2 is connected with a pressure plate 3 through the box clamp, a sprue 4 is arranged in the middle box 2, the bottom end of the sprue 4 is communicated with an ingate 5 positioned in the lower box 1, the ingate 5 is communicated with a cavity arranged in the middle box 2, the top end of the sprue 4 is provided with a water gap ring 6,

the pressing plate 3 comprises a frame body 7, the frame body 7 is matched with the top end of the middle box 2 in profile, a pressing ring 8 is arranged in the frame body 7, and the bottom of the pressing ring 8 is in contact with the top of a sand core 9 in the middle box 2 and compresses the sand core 9.

Compared with the prior art, the utility model, have following advantage:

this kind of structural style's visual sand box, its simple structure, design benefit, rationally distributed. The condition of the internal sand core cannot be observed in the use process of the traditional closed sand box, and even if the sand core is partially damaged under the pressure action of the upper box body, a user cannot see the sand core, so that a large amount of waste products or defective products can be caused. To above-mentioned problem, this application designs out a sand box of special construction, and the top of this sand box is the clamp plate of fretwork design, and inside the sand box can be observed to the fretwork department through the clamp plate, in case the psammitolite has the damage like this, the user can in time change, saves a large amount of costs for the enterprise. The sand box not only can play the same pressing role as the upper box, but also is convenient for people to observe the specific conditions in the sand box, thereby avoiding unnecessary loss. And the manufacturing process is simple, the manufacturing cost is low, so that the novel LED lamp has multiple advantages, is particularly suitable for popularization and application in the field, and has a very wide market prospect.

Drawings

Fig. 1 is a schematic structural diagram of an embodiment of the present invention.

Fig. 2 is a plan view of a platen portion in an embodiment of the present invention.

Detailed Description

The following description will explain embodiments of the present invention with reference to the drawings. As shown in fig. 1: a visual sand box comprises a lower box 1, the top end of the lower box 1 is connected with a middle box 2 through a box clamp, the top end of the middle box 2 is connected with a pressure plate 3 through the box clamp, a sprue 4 is arranged in the middle box 2, the bottom end of the sprue 4 is communicated with an ingate 5 positioned in the lower box 1, the ingate 5 is communicated with a cavity arranged in the middle box 2, the top end of the sprue 4 is provided with a water gap ring 6,

The utility model discloses visual sand box's working process as follows: after the lower box 1 and the middle box 2 are combined through a box clamp, a sand core 9 is placed into a cavity, then a pressure plate 3 is pressed at the top end of the middle box 2 and is fixed by the box clamp, molten steel, molten iron, molten aluminum and other liquid high-temperature metals are poured into a sprue 4 through a water gap ring, the liquid metals enter the cavity through the sprue 4 and an ingate 5, the liquid level gradually rises until the sand core 9 is covered, the metals are solidified after cooling, the sand core 9 is pulverized, the whole sand box is disassembled, and a metal casting is taken out;

in the process of splicing the sand boxes, an operator can observe the sand core 9 through the gap between the frame body 7 and the pressure ring 8, and if the sand core 9 is damaged, the sand core can be replaced in time, so that the problem that unqualified products are produced due to damage of the sand core can be fundamentally avoided.
