Detailed Description
The technical scheme of the invention is further explained by combining the attached drawings.
Referring to fig. 1-5, the preparation mold adopted by the process of the invention is used for preparing the annular reinforcing rib. The annular reinforcing rib is obtained after molding by putting an annular reinforcing steel bar structure in an annular casting mold cavity and injecting casting materials. The annular reinforcing structure comprises at least two coaxially extending and spaced apart annular reinforcing bars secured to each other.
Referring to fig. 1 to 3, the outer mold 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 cylinder 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 block 4 protruding outwards and arranged on the rectangular plate body 1, a locking column 5 fixedly arranged on the first connecting block 4, a second connecting block 6 protruding outwards and arranged on the rectangular plate body 1, and a locking hole 7 arranged on the second connecting block 6 and used for penetrating through the locking column 5.
In this embodiment, the locking post 5 is provided with an external thread, the locking mechanism further includes a nut 8 which is sleeved on the locking post 5, and the nut 8 is used for abutting the second connecting block 6 against the first connecting block 4 when the rectangular plate body 1 is in a cylindrical state. Referring to fig. 1, when the rectangular plate 1 is in a cylindrical state, the upper and lower locking posts 5 penetrate into the two locking holes 7 in a one-to-one correspondence manner, and the nut 8 is screwed into the nut 8 leftwards, so that the nut 8 pushes the second connecting block 6 until abutting against the first connecting block 4, and the rectangular plate 1 in the cylindrical state is completely closed along the circumferential direction thereof.
In the present embodiment, the first connecting block 4 and the second connecting block 6 are respectively disposed on two opposite ends of the same side of the rectangular plate 1 along the length direction.
Referring to fig. 4-5, the internal mold 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 does not necessarily form a standard circle by the cross section of the rectangular plate body under the action of the locking mechanism, the inner die 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 can form a standard circle, and the annular reinforcing rib with a standard shape can be manufactured subsequently.
When the inner mold is inscribed in the outer mold, an annular casting mold cavity for preparing an 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 forms from the top down in proper order with one heart piling up locate be in the rectangular plate body 1 of 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 can completely block the top of the annular casting die cavity below the upper inner die, 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, when the upper inner mold is concentrically stacked on the lower inner mold, 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 through the lower surface of the annular bottom plate 3.
A preparation process for the annular reinforcing rib is realized by the preparation die, and comprises the following steps:
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, so that the rectangular plate body is completely closed along the circumferential direction;
(2) concentrically filling a cylinder body 2 with the bottom externally connected with an annular bottom plate 3 into the cylinder until the bottom is touched; wherein, the outer diameter of the annular bottom plate 3 is the same as the inner diameter of the cylinder, and an annular casting mold cavity for preparing the annular reinforcing rib is formed between the outer periphery of the cylinder body 2 and the inner periphery of the cylinder;
(3) placing the annular steel bar structure on the annular bottom plate 3, injecting a casting material into the annular casting mold cavity, and scraping the top of the annular steel bar structure by a scraper under the matching of the annular upper surface 9 after the annular steel bar structure is fully injected;
(4) repeating the step (2) and the step (3) in sequence alternately until a corresponding number of cylinders 2 are stuffed in the cylinder; the two adjacent annular bottom plates 3 respectively form an upper sealing cover and a lower sealing bottom of the annular casting mold cavity; because the inner diameter of the lower surface of the annular bottom plate 3 is smaller than the inner diameter of the upper surface (namely the outer diameter of the cylinder 2), the lower surface of the annular bottom plate 3 in the upper cylinder 2 is abutted against the top of the lower cylinder 2;
the corresponding numbers referred to herein refer to those actually required, it being noted that the total height of the stacked cartridges 2 should be less than or equal to the height of the cylinder;
