Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bellows forming molds, in particular to a mold for forming hydraulic armored bellows. Background Art
[0002] Generally, the hydraulic bellows forming mold uses an inlaid type of mold core and outer mold ring. The mold material is generally selected from high-hardness and good wear-resistant steel. The size of the outer diameter of the mold core is matched with the size of the inner diameter of the outer mold ring to form a tight fit. However, there is currently no such mold for forming armored bellows with multiple waves in one step. Originally, when manufacturing armored bellows, each single wave was formed first, then an armored ring was put on, and then another wave was formed, and so on in a cycle to produce armored bellows.
[0003] However, this method not only has low efficiency, but also the formed armored bellows have poor dimensional consistency, and the disassembly and assembly of the traditional bellows forming mold are not convenient. Summary of the Utility Model
[0004] The purpose of the utility model is to solve the defects existing in the prior art, and to provide a mold for forming hydraulic armored bellows.
[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0006] A mold for forming hydraulic armored bellows, including an outer mold ring and a mold core. The outer mold ring and the mold core are sleeved with each other. A placement groove is opened on the upper surface of the outer mold ring. The mold core includes a first half mold core and a second half mold core. The first half mold core and the second half mold core are closely attached along the side wall to form a complete ring.
[0007] The first half mold core includes a mold core ring. A fixing ring is fixedly connected to the inner ring of the mold core ring. A clamping groove is opened in the inner ring of the fixing ring. A placement ring is fixedly connected to the outer ring of the mold core ring. The placement ring is matched with the placement groove in terms of size. The placement ring is nested in the placement groove on the upper surface of the outer mold ring. The first half mold core and the second half mold core have the same structure.
[0008] Preferably, an inclined surface is opened on the lower surface of the placement ring. A disassembly and assembly groove is opened on the upper surface of the outer mold ring. The disassembly and assembly groove is communicated with the placement groove.
[0009] Preferably, there are four disassembly and assembly grooves, and the four disassembly and assembly grooves are arranged equidistantly along the center of the outer mold ring.
[0010] Preferably, the placement groove is matched with the mold core in terms of size. The mold core ring, the clamping groove and the placement ring are integrally formed.
[0011] The beneficial effects of the utility model are as follows:
[0012] 1. In the present utility model, through the design of the fixing ring and the clamping groove, the armored ring is placed into the clamping groove for clamping connection. The first half die core and the second half die core are combined, and then the die core is placed into the outer film ring. The die core and the outer film ring form a complete mold. After the corrugated pipe is formed, the outer film ring and the die core are removed, and the armored ring is naturally embedded in the wave trough of the corrugated pipe to play a strengthening role. Through multiple molds, the socket installation of multiple armored rings can be achieved at one time. Compared with the traditional manufacturing method of armored corrugated pipes, where each single wave is formed first, an armored ring is put on, and then another wave is formed, and this process is repeated to produce the armored corrugated pipe, the production efficiency is greatly improved.
[0013] 2. In the present utility model, the outer film ring is provided with a four-equal-part disassembly groove, and an inclined surface is provided on the placing ring of the first half die core. During disassembly, only need to insert a flat screwdriver along the disassembly groove into the placing groove and pry up the first half die core, which is convenient for disassembly and assembly, and can better ensure that the first half die core will not be deformed due to force during the use of the mold, thus avoiding the occurrence of clamping marks and corrugation waveform defects on the formed armored corrugated pipe.
