Description

Technical Field

[0001] This utility model relates to the field of underwater protective sleeve manufacturing technology for submarine cables, specifically a rapid casting mold for submarine cable protective sleeves. Background Technology

[0002] With the ever-increasing demand for submarine cables, the demand for submarine cable accessories is also growing rapidly. As a key accessory for submarine cables, the most common manufacturing process for protective sleeves is currently mold casting.

[0003] Traditional protective sleeve casting molds are mostly integral or modular structures secured by multiple bolts, resulting in large size and heavy weight. After each casting, numerous bolts must be removed for demolding, and reassembly requires realignment and tightening, making the entire process time-consuming and labor-intensive, severely restricting production efficiency and increasing the workload of operators. Furthermore, traditional molds are simply designed, typically with only a single gate. During casting and sealing, the raw material continuously solidifies, inevitably causing volume shrinkage, leading to defects such as shrinkage cavities, bubbles, and dimensional deviations inside the protective sleeve. These defects directly reduce the product's density, mechanical strength, and appearance quality.

[0004] Therefore, a rapid casting mold for submarine cable protection sleeves is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a rapid casting mold for submarine cable protection sleeves to solve the problems mentioned in the background art.

A mold core shaft is vertically arranged inside the two semi-circular shells. A connecting hole is vertically opened through the bottom surface of the circular base. A bolt is vertically arranged below the circular base. The top of the bolt is threaded through the connecting hole and extends into the mold core shaft and is threadedly connected to the inner wall of the mold core shaft.

The two dovetail guide blocks are fixedly connected to the corresponding V-shaped blocks, and the two V-shaped blocks are pressed into contact with the outer surface of the adjacent semi-circular shell.

[0012] Preferably, a threaded rod is connected to the outside of the dovetail guide block via a bearing seat. The outer end of the threaded rod extends through the inner wall of the dovetail groove to the outside of the dovetail groove block. The surface of the threaded rod is threadedly connected to the inner wall of the dovetail groove block. A handwheel is fixedly sleeved on the outer end surface of the threaded rod.

[0013] Preferably, the mold placement platform includes two symmetrical placement plates, a connecting frame is uniformly fixed between the two placement plates, flanges are welded to the bottom ends of the two semi-circular shells, and a bolt is provided on the outer side of the bottom end of the semi-circular shell. The bottom end of the bolt passes through the flange and the circular base in sequence until it extends into the interior of the lower placement plate and is threadedly connected to the inner wall of the lower placement plate.

[0014] Preferably, the top of the mold core shaft is respectively engaged with two stepped cover plates arranged symmetrically on the left and right, and the inner sides of the top of the two semi-circular shells are respectively provided with arc-shaped guide grooves corresponding to the positions of the two stepped cover plates.

[0015] Preferably, the outer edge of the bottom end of the stepped cover plate does not contact the inner wall of the guide channel.

[0016] Preferably, thin strip partitions are vertically arranged between the front and rear ends of the two stepped cover plates, and a long groove is vertically formed on the surface of the mold core shaft corresponding to the position of the thin strip partition. A slot is formed on the inner wall of the two semi-circular outer shells corresponding to the position of the thin strip partition. The inner and outer ends of the thin strip partitions extend into the long groove and the slot, respectively.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the rapid casting mold for the submarine cable protective sleeve,

[0018] 1) During the casting process, by using the V-shaped blocks pressed on the semi-cylindrical shell, the semi-cylindrical shell and the mold core shaft can be quickly opened and closed by rotating the handwheel, thereby improving the efficiency of mold assembly and disassembly.

[0019] 2) The height of the protective sleeve can be limited by the stepped cover plate that is snapped onto the mold core shaft. The thin strip partition that is snapped onto the mold core shaft cleverly divides the protective sleeve into two C-shaped semi-cylinders, which makes the subsequent mold assembly and disassembly of the protective sleeve extremely convenient.

[0020] 3) The pouring funnel formed by the guide channel and the outer slope of the stepped cover plate can ensure that there is a continuous supply of residual material to replenish the protective sleeve during curing shrinkage, effectively solving the problems of dimensional deviation and bubble defects caused by curing shrinkage.
