Detailed Description
The technical scheme of the invention is further explained by combining the attached drawings.
The preparation mold for the annular reinforcing rib comprises an outer mold component and an inner mold component which is arranged in the outer mold component in an inscribable mode.
Referring to fig. 1 to 3, the outer mold assembly comprises a rectangular plate 1 which can be wound into a cylinder, and a locking mechanism which is arranged on the rectangular plate 1 and is used for locking the rectangular plate in a cylindrical state. The rectangular plate body 1 is made of a material with certain toughness and elasticity, and is enclosed and locked in a casting process to be in a cylindrical state through the arrangement, and the locking mechanism is unlocked and unfolded when the mold is opened. The die opening difficulty is greatly reduced, the annular reinforcing ribs molded by casting cannot be damaged basically during die opening, and the yield is high.
The locking mechanism comprises a first connecting
In this embodiment, the
In the present embodiment, the first connecting
Referring to fig. 4-5, the internal mold assembly comprises a cylinder 2 and an annular bottom plate 3 externally connected to the bottom of the cylinder 2; the outer diameter of the annular bottom plate 3 is the same as the inner diameter of the rectangular plate body 1 in a cylindrical state. Because the rectangular plate body 1 in the cylindrical state is not necessarily exactly enclosed to form a standard circle in cross section under the action of the locking mechanism, the inner die assembly is concentrically plugged into the rectangular plate body 1 in the cylindrical state and is propped open under the action of the annular bottom plate 3, so that the cross section of the rectangular plate body 1 can form a standard circle, and the annular reinforcing rib with a standard shape can be manufactured subsequently.
When the inner mold assembly is inscribed in the outer mold assembly, an annular casting mold cavity for preparing the annular reinforcing rib is formed between the outer peripheral portion of the cylinder body 2 and the inner peripheral portion of the rectangular plate body 1 in a cylindrical state. When actually pouring, a plurality of centre form subassemblies from last down in proper order with one heart the locating rectangular plate body 1 that is in the drum state, through this setting, can a plurality of annular strengthening ribs of one shot forming, machining efficiency is higher. Meanwhile, the lower annular bottom plate 3 and the upper annular bottom plate 3 form a lower sealing bottom and an upper sealing cover of the annular casting mold cavity respectively, and mold cost is saved.
In this embodiment, the top of the barrel 2 is provided with an annular upper surface 9 parallel to the horizontal plane, by which arrangement, when the casting material is injected into the annular casting mold cavity, since the bottom surface, the inner peripheral surface and the outer peripheral surface thereof all abut against the mold for molding, wherein the bottom surface abuts against the upper surface of the annular bottom plate 3, the inner peripheral surface abuts against the outer peripheral surface of the barrel 2, and the outer peripheral surface abuts against the inner peripheral surface of the rectangular plate body 1 in a cylindrical state; and the top of the reinforcing rib is required to be subjected to strickling treatment by matching a horizontal annular upper surface 9 with a scraper so as to prepare the required annular reinforcing rib.
In the present embodiment, the inner peripheral portion of the cylindrical body 2 is tapered from the top to the bottom. Through this setting, on the basis that the annular upper surface 9 of guaranteeing barrel 2 possesses certain pressure-bearing capacity, the consumptive material and the cost of mould have further been saved.
In this embodiment, since the annular bottom plate 3 is externally connected to the bottom of the cylinder 2, and the outer circumference of the cylinder 2 is a standard cylindrical surface, the inner diameter of the upper surface of the annular bottom plate 3 is the same as the outer diameter of the cylinder 2. Meanwhile, in order to ensure that the annular bottom plate 3 of the upper inner die assembly can completely block the top of the annular casting die cavity below the upper inner die assembly, the inner diameter of the lower surface of the annular bottom plate 3 is smaller than that of the upper surface of the annular bottom plate. With this arrangement, it is possible to abut against the top of the casting material in the annular casting mold cavity and the annular upper surface 9 of the cylinder 2 via the lower surface of the annular bottom plate 3 when the upper inner mold assembly is concentrically stacked on the lower inner mold assembly.
The following specifically explains the working process of this embodiment:
die assembly:
(1) the rectangular plate body 1 is encircled to form a cylinder, and is locked in a cylinder state through a locking mechanism;
(2) the internal mold assembly is concentrically plugged into the rectangular plate body 1 in a cylindrical state until the internal mold assembly touches the bottom;
(3) placing the annular steel bar structure on the annular bottom plate 3, injecting a casting material, and scraping the top of the annular steel bar structure by the scraper under the matching of the annular upper surface 9 after the annular steel bar structure is fully injected;
(4) and (4) repeating the step (2) and the step (3) in sequence and alternately until the number of the placed internal module meets the requirement.
Opening the mold:
(1) after casting molding, unlocking the locking mechanism, and unfolding the rectangular plate body 1 in a cylindrical state;
(2) sequentially taking out the stacked internal mold assemblies from top to bottom;
(3) and (4) reversely buckling the inner die assembly, and separating the inner die assembly from the molded annular reinforcing rib.
