Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of manufacturing mooring anchors for offshore oil platforms and wind power platforms, in particular to a casting mould for a hanging ear of a deep-water pile anchor. Background Art
[0002] As the exploration of marine resources is increasingly developing towards the deep sea, the deep-sea mooring anchoring scheme has greatly affected the installation efficiency of the mooring system. For geological areas with deep water and soft seabed soil environment, a gravity penetration mooring anchor can be used. Through free fall on the installation ship, the anchor body is driven into the seabed under the action of its own weight, thereby completing rapid mooring. This type of pile anchor structure includes a cast top connection lug for connection with the mooring anchor chain. This type of top connection lug needs to be integrally cast to ensure the strength of the connection. Its surface is complex, and a special casting mold solution needs to be designed for the casting production of this type of top connection lug. Summary of the invention
[0003] The utility model aims to solve the above technical problems and provides a combined casting mold for producing a top connecting lug of a pile anchor for deep-water mooring.
[0004] In order to achieve the above technical objectives and meet the above technical requirements, the technical solution adopted by the utility model is: a deep-water pile anchor lug casting mold, characterized in that: it includes an upper mold, a core mold, and a lower mold, the core mold is fitted between the upper mold and the lower mold, and a casting cavity is formed between the upper mold, the core mold, and the lower mold. An annular upper mold cavity is arranged at the bottom of the upper mold, and a gate, a riser, and an air hole are arranged on the upper mold. The gate is connected with the upper mold cavity, and the lower mold includes a lower mold A and a lower mold B. A U-shaped lower mold cavity is arranged in the middle of the lower mold A, and channels connected with the riser and the air hole are respectively arranged on both sides of the lower mold cavity. A positioning hole is arranged in the middle of the lower mold A, and the lower mold B has the same structure as the lower mold A.
[0005] Preferably, the core mold comprises a core plate, positioning guide pillars cooperating with positioning holes are symmetrically arranged at the bottom of the core plate, and arc portions are symmetrically arranged on both sides of the core plate.
[0006] Preferably, the upper portion of the positioning guide column is configured to be cylindrical, and the lower portion is configured to be conical.
[0007] Preferably, the gate is configured to be tapered.
[0008] Compared with the traditional structure, the utility model has the following beneficial effects: the structure is simple, and the design of the upper mold, the core mold, and the two lower molds can ensure the integral casting of the top connecting lug of the deep-water mooring pile anchor, and ensure the strength required for its connection; through the setting of the riser and the air hole, it is ensured that the casting is fully compensated for shrinkage while the gas is reasonably discharged, avoiding defects such as looseness and air holes, improving the qualified rate of the casting, and can form batch production.

[0021] The utility model is further described below.
[0022] See attached Figure 1-10A deepwater pile anchor lug casting mold, characterized in that it includes an upper mold 1, a core mold 2, and a lower mold, the core mold 2 is fitted between the upper mold 1 and the lower mold, and a casting cavity is formed between the upper mold 1, the core mold 2, and the lower mold. An annular upper mold cavity 14 is arranged at the bottom of the upper mold 1, and a gate 12, a riser 11, and an air hole 13 are arranged on the upper mold 1. The gate 12 is connected with the upper mold cavity 14, and the lower mold includes a lower mold A3 and a lower mold B4. A U-shaped lower mold cavity 31 is arranged in the middle of the lower mold A3, and channels 32 connected with the riser 11 and the air hole 13 are respectively arranged on both sides of the lower mold cavity 31. A positioning hole 33 is arranged in the middle of the lower mold A3, and the lower mold B4 has the same structure as the lower mold A3.
[0023] In this preferred embodiment, the core mold 2 includes a core plate 21 , and positioning guide pillars 23 cooperating with positioning holes are symmetrically arranged at the bottom of the core plate 21 , and arc portions 22 are symmetrically arranged on both sides of the core plate 21 .
[0024] In this preferred embodiment, the upper portion of the positioning guide column 23 is configured to be cylindrical, and the lower portion is configured to be conical.
