Abstract
The utility model provides a retractable circular inner mold apparatus, belonging to the field of molds for cavity members. The retractable circular inner mold apparatus is capable of reducing the demolding force of products, improving the surface quality of the products, and decreasing the rejection rate in the production process. The inner mold apparatus comprises a cylinder-shaped inner mold formed by connecting three arc plates through hinges. The interior of the cylinder-shaped inner mold is provided with a limit backing pin, a limit connecting rod, and a contraction connecting rod. In the product casting process, the inner mold of the apparatus is in a mold closing state, i.e., being a complete cylinder. As the crushing stress generated by solidification and contraction of cement is not enough to make the inner mold deform, the apparatus can not cause the structure of the products to be damaged. When the strength of the products reaches a demolding strength, the inner mold is operated to retract inwardly, thereby greatly reducing the demolding force of the products. The components of the apparatus are all common-used members or standard members. The apparatus is convenient in maintenance, simple in operation, and low in manufacture cost.

The specific embodiment
Below in conjunction with example the utility model is described in detail.
Internal mold of the present invention is comprised of 8 members, comprises 9, three blocks of circular arc plates of limited block, and the first arc plate 3, the second arc plate 4 and three-arc plate 5 are connected through the hinge together.Wherein torsionspring is equipped with in the hinged place of the second spacing connecting rod 2 and the first arc plate 3.The inboard of the first arc plate 3 is welded with the reinforcement of some, limited block 9 is welded on the reinforcement of the first arc plate 3, the first spacing connecting rod 1 and the 3rd shrinks connecting rod 8 and is connected through the hinge on member 3, and the first spacing connecting rod 1 the second spacing connecting rod 2 and the 3rd that is connected through the hinge shrinks connecting rod 8.The 3rd shrinks connecting rod 8 is connected with the first contraction connecting rod 6, the second contraction connecting rod 7 by hinge, and first shrinks connecting rod 6 is connected with the second arc plate 4 by hinge, and second shrinks connecting rod 7 is connected with three-arc plate 5 by hinge.
The realization that internal mold shrinks:
One end of the second spacing connecting rod 2 links to each other with the first arc plate 3 by hinge and forms revolute pair and in the hinged place torsionspring is housed, pull the second spacing connecting rod 2, make the second spacing connecting rod 2 turn to limited block 9 places, this moment second, spacing connecting rod 2 drove the first spacing connecting rod 1, connecting rod 8 is shunk in the first spacing connecting rod 1 traction the 3rd, shrink under the effect of connecting rod 8 pulling force the 3rd, first shrinks connecting rod 6 and second shrinks connecting rod 7 to the circle internal motion, thereby realize the contraction of internal mold, internal mold shrinks has eliminated the compression of product and interior intermode, thereby reaches the purpose of the smooth demoulding; Unclamp and pull the second spacing connecting rod 2 external force, then the second spacing connecting rod 2 returns to initial position in the effect of torsionspring, makes it become a complete cylinder thereby drive the first spacing connecting rod 1, first shrinks the matched moulds of connecting rod 6, the second contraction connecting rod 7, the 3rd contraction connecting rod 8, motion realization internal mold.Can dwindle the 3D figure of internal mold organization shown in Fig. 2,3.
The first spacing connecting rod 1, the second spacing connecting rod 2, the three shrink connecting rod 8 and the first arc plate 3 composition crank and rocker mechanisms, and when the second spacing connecting rod 2 was positioned at initial position shown in Figure 1, internal mold was in the matched moulds state, was a complete cylinder.This moment, the first spacing connecting rod 1 and the second spacing connecting rod 2 drew a straight line, and were positioned at the dead-centre position.So that whole internal mold can not dwindle inward because of the contraction extruding force that produces in the workpiece process of setting, thereby cause workpiece to cave in.
