Description
Technical Field
The utility model relates to a seal structure especially relates to an airtight seal structure that detects of aluminum alloy die casting.
Background
The automobile casting forming process sequentially comprises the following steps: high-temperature smelting → slagging and dehydrogenation → die assembly → molten metal injection filling → pressure maintaining molding → die opening of the die for casting cooling → finished casting product. The molten metal enters the die cavity until the die cavity is filled, and the injection punch head transmits pressure to the die cavity through the solidified excess material and the metal at the intersection part, so that the solidified metal is crystallized under the pressure to obtain a casting with compact structure.
In the casting forming process, different machines, different products and different technical parameters are adopted, so that the defect characteristics of the produced products are inconsistent. In order to avoid sending products with defect characteristics such as cold shut, cracks, surface layer fracture, shrinkage cavity and the like to customers, the cavity of the product needs to be subjected to airtight detection.
Referring to fig. 1, fig. 1 is a schematic structural view of a casing casting 10. The opening edge of the shell casting 10 is provided with an arc-shaped groove 11. For the airtightness detection of such a casting with the arc-shaped groove 11, the inventors have designed a sealing structure 20. Referring to fig. 2, fig. 2 is a schematic structural view of a sealing structure 20. The sealing structure 20 comprises an integrated bottom plate 21, and the top surface of the integrated bottom plate 21 is provided with an arc-shaped bulge 22 matched with the arc-shaped groove 11. Along the opening contour of the shell casting 10, a groove 23 is arranged on the top surface of the integrated bottom plate 21 and the arc surface of the arc protrusion 22, and an integrated sealant 24 is arranged on the groove 23.
When the airtight device is used, the opening surface of the shell casting 10 is correspondingly placed on the integrated base plate 21, the opening edge of the shell casting 10 is abutted against the integrated sealant 24, a closed space is formed in the cavity of the shell casting 10, and then the airtightness of the shell casting 10 is detected by adopting an airtightness instrument.
Although the sealing structure 20 can achieve the sealing purpose, when the integrated sealant 24 is installed in the groove 23, the margin of the integrated sealant 24 is almost extruded to the joint between the groove 23 on the arc surface and the groove 23 on the plane surface, so that the integrated sealant 24 has poor sealing performance at the joint, and the integrated sealant 24 is easily damaged in the using process. In addition, the integrated bottom plate 21 and the arc-shaped protrusion 22 are integrally formed, so that the difficulty in processing the groove 23 on the arc-shaped surface is high, and the difficulty in processing the joint between the groove 23 on the arc-shaped surface and the groove 23 on the plane is also high, which greatly increases the manufacturing difficulty and the replacement cost.
In addition, the inventor states here that the technical solution described in the background art is only used for illustrating the technical problem to be solved by the present patent, and the inventor does not admit the technical solution to belong to the prior art.
SUMMERY OF THE UTILITY MODEL
Based on this, the utility model aims to provide an airtight seal structure that detects of aluminum alloy die casting, it has sealed effect better, life is longer, change and cost of maintenance lower advantage.
An aluminum alloy die casting airtight detection sealing structure is used for sealing a shell casting with an arc-shaped groove at an opening edge, and comprises:
the bottom plate is provided with a sealing groove corresponding to the opening outline of the shell casting, and a primer is arranged in the sealing groove;
the base is arranged on the bottom plate and is matched with the arc-shaped groove;
the clamping plate is detachably arranged on the base and is matched with the arc-shaped groove;
and the sealing colloid is arranged between the base and the clamping plate, is matched with the arc-shaped groove and is attached to the bottom glue.
Compared with the prior art, airtight detection seal structure of aluminum alloy die casting with the sealed separately design of glue of original integral type, design into primer and sealing colloid respectively, the primer is used for the opening limit of sealed casing foundry goods, sealing colloid is used for sealing up the arc recess on the opening limit, reach sealed effect through extrusion between primer and the sealing colloid, this design can not only play sealed effect, can reduce change and cost of maintenance moreover, improves life. Then, this aluminum alloy die casting airtight detection seal structure only need process out the seal groove on the bottom plate, and this machined surface is the plane, need not to process the seal groove on the arcwall face, helps reducing the processing degree of difficulty and manufacturing cost. Moreover, the airtight detection sealing structure for the aluminum alloy die casting does not have the technical problem that the integral sealant allowance existing in the technical scheme in the background art is almost extruded at the joint between the groove on the arc-shaped surface and the groove on the plane.
Further, the clamping plate is connected with the base through a fixing screw, and the fixing screw penetrates through the sealing colloid. Fix the colloid that seals on the base through splint and fixed screw, splint can make the contact of colloid and primer inseparabler to the clamp force of colloid that seals, fixed screw to the colloid that seals to help improving the airtight sealed effect that detects seal structure of aluminum alloy die casting.
Furthermore, a through hole is formed in the sealing colloid, a shaft sleeve is arranged in the through hole, and the fixing screw penetrates through the shaft sleeve to be connected to the base. In the process of mounting or dismounting the sealing colloid, the contact between the fixing screw and the sealing colloid is reduced, and the damage of the fixing screw to the sealing colloid is reduced.
Furthermore, be equipped with first constant head tank on the base, be equipped with the second constant head tank on the splint, the one end of axle sleeve is installed in first constant head tank, the other end of axle sleeve is installed in the second constant head tank. The shaft sleeve is positioned through the first positioning groove and the second positioning groove, and the assembly of the sealing structure for the airtight detection of the aluminum alloy die casting is facilitated. And when the clamping plate is assembled, the shaft sleeve can abut against the bottom surfaces of the first positioning groove and the second positioning groove, so that the relative position between the clamping plate and the base is determined. Through the clamp force of control splint to sealed colloid, the deformation of controlling sealed colloid effectively helps further improving sealed effect.
Further, the thickness of the sealing colloid is larger than the width of the bottom glue. Contributing to further improving the sealing effect.
Further, aiming at two ends of the surface, in contact with the base glue, of the sealing glue body, sealing blocks are correspondingly arranged on the base glue body, and the width of each sealing block is larger than the thickness of the sealing glue body. The width of the bottom glue between the two sealing blocks is smaller than the thickness of the sealing glue body. On one hand, the sealing blocks can effectively seal two ends of the surface of the sealing colloid, which is in contact with the bottom glue, and the sealing effect is further improved. On the other hand, the width of the bottom glue between the two sealing blocks is still smaller than the thickness of the sealing glue body, so that the compression amount of the bottom glue can be reduced, the gas of the gas detection is prevented from being filled into the sealing groove, and the detection precision of the gas detection is further prevented from being influenced by the overlarge compression amount of the bottom glue.
Further, the base is detachably connected to the bottom plate. The base is fixedly connected to the bottom plate through bolts. The base and the bottom plate are separately processed, so that the processing difficulty, the replacement and the maintenance cost are reduced.
For a better understanding and an implementation, the present invention is described in detail below with reference to the accompanying drawings.
