Technical Field

[0001] The present application relates to the technical field of marine mold clamping molds, and more specifically, to a marine positioning mold clamping device. Background Art

[0002] In the production of a hull, it is necessary to form the hull through the processing of a hull model. The hull model is usually a fiberglass mold that requires upper and lower mold clamping. In order to improve the processing accuracy of the hull, it is necessary to position the upper and lower molds of the fiberglass mold during mold clamping.

[0003] In the prior art, a plurality of positioning holes are provided at the edges of the upper and lower molds of the fiberglass mold, and steel balls are embedded in the positioning holes. The steel balls cooperate with the positioning holes of the upper and lower molds for limiting, and the edges of the mold are clamped by a plurality of U-shaped steel clamps; before installing the U-shaped steel clamps, the worker needs to roughly measure the size of the opening of the U-shaped steel clamp first, compare it with the thickness of the upper and lower molds of the mold when they are clamped together, adjust the opening of the U-shaped steel clamp to a close size by tools such as a hammer, and then install the U-shaped steel clamp with the adjusted opening size onto the mold and clamp it. Each U-shaped steel clamp is operated in the same way, so as to complete the positioning mold clamping of the fiberglass mold. When the hull is cured, all the U-shaped steel clamps need to be disassembled. The worker knocks off all the U-shaped steel clamps with a hammer, and then inserts the head of an iron wedge into the mold clamping seam of the upper and lower molds, and pries open the upper mold by knocking on the iron wedge to complete mold opening. This kind of steel ball positioning mold clamping device has a simple structure and low production cost, but there are the following problems: 1. The labor intensity of the worker is large, the operation steps are cumbersome, and it is time-consuming and laborious to adjust the opening of the U-shaped steel clamp and the installation process by a hammer; 2. Repeatedly using tools such as a hammer to install and disassemble the U-shaped steel clamps causes serious wear of the U-shaped steel clamps and is likely to cause damage to the fiberglass mold, affecting the service life of the mold; 3. When using an iron wedge to pry open the upper mold, it is easy to scratch the inner surface of the mold, resulting in errors during the processing of the hull, affecting the processing accuracy, and causing the mold to need to be repaired repeatedly, affecting the production efficiency of the product.

[0020] Now a marine positioning die closing device provided by an embodiment of this application will be described.

[0021] Please refer to Figure 1 and Figure 2 , which is a schematic structural diagram of the present utility model. The marine positioning die closing device includes an upper die 1 and a lower die 2. The upper die 1 cooperates with the lower die 2. A plurality of corresponding positioning grooves 3 are provided at the edges of the upper die 1 and the lower die 2. Positioning steel balls are arranged in the positioning grooves 3; the positioning grooves 3 are convex hemispherical shapes. The positioning grooves 3 of the upper die 1 and the lower die 2 correspond to each other to form a complete spherical groove, and the positioning grooves 3 cooperate with the positioning steel balls; a through wire hole is provided in the middle of the positioning steel ball, and the positioning grooves 3 of the upper die 1 and the lower die 2 are provided with limiting holes corresponding to the through wire hole, and the through wire hole and the limiting hole are on the same straight line; the through wire hole and the corresponding limiting hole are connected by a positioning member 4, and the positioning member 4 limits the positioning steel ball.

[0022] During use, the worker places the positioning steel balls into the corresponding positioning grooves 3 on the lower die 2, keeping the through holes of the positioning steel balls vertical. Then, the upper die 1 is covered. The positioning grooves 3 of the upper die 1 and the lower die 2 cooperate with the positioning steel balls, and the limiting holes on the positioning grooves 3 and the through holes of the positioning steel balls are on the same straight line. The positioning member 4 is inserted into the through holes of the positioning steel balls and locked, completing the alignment and positioning of the upper die 1 and the lower die 2.

[0023] Specifically, threads are provided in the through holes of the positioning steel balls, and the positioning member 4 is threadedly connected to the through holes. The positioning and closing of the mold are achieved through the threaded connection between the positioning member 4 and the through holes of the positioning steel balls. In this embodiment, the positioning member 4 is specifically an internal hexagonal screw, which is tightened in cooperation with the through holes. The operation steps are simple, the installation and disassembly are convenient, and the labor intensity of the worker is reduced.

[0024] Furthermore, gaskets are provided between the positioning member 4 and the upper die 1 and the lower die 2 to prevent damage to the surfaces of the upper die 1 and the lower die 2 when the positioning member 4 is locked, and to extend the service life of the mold.

[0025] Furthermore, the positioning steel balls in the positioning grooves 3 at both ends of the upper die 1 and the lower die 2 are connected with a connecting member 5. A lifting ring 6 is provided at the top of the connecting member 5, and the lifting ring 6 is connected to the hook of an electric hoist through a structure such as a lifting rope or a safety belt. After the hull is cured, the worker removes the positioning members 4 on all the positioning grooves 3 and retains the connecting member 5. The lifting ring 6 of the connecting member 5 is connected to the hook of the electric hoist through a structure such as a lifting rope or a safety belt. The worker controls the electric hoist, and drives the entire mold to rise through the lifting ring 6. When the mold rises to about 5 cm away from the mold rack, the rising is stopped. At this time, a wooden wedge is inserted into the closing seam between the upper die 1 and the lower die 2. By using the self-weight of the mold, the mold can be easily opened. The wooden wedge is not easy to damage the mold, avoiding scratching the inner surfaces of the upper die 1 and the lower die 2 during mold opening, extending the service life of the mold, improving the processing accuracy of the hull, being safe in operation, time-saving and labor-saving, and improving the mold opening efficiency.

[0026] Specifically, the connecting member 5 is threadedly connected to the through holes of the corresponding positioning steel balls.

[0027] Specifically, the number of the connecting members 5 is at least four. In this embodiment, the number of the connecting members 5 is four, which are symmetrically distributed at both ends of the upper die 1, avoiding the mold from falling off the structure such as the lifting rope or the safety belt, and improving the stability and safety of the mold during rising.

[0028] Furthermore, the positioning grooves 3 are evenly distributed at the edges of the upper die 1 and the lower die 2.

[0029] The working process of the present utility model is as follows: During use, the worker places the positioning steel balls into the corresponding positioning grooves 3 on the lower die 2, keeping the through-wire holes of the positioning steel balls vertical. Then, the upper die 1 is covered. The positioning grooves 3 of the upper die 1 and the lower die 2 cooperate with the positioning steel balls. The positioning member 4 is inserted into the through-wire holes of the positioning steel balls and locked, completing the positioning and clamping of the upper die 1 and the lower die 2. After the hull is cured, the mold needs to be opened. The worker removes the positioning members 4 on all the positioning grooves 3, leaving the connecting member 5. The lifting ring 6 of the connecting member 5 is connected to the hook of the electric hoist through a structure such as a lifting rope or a safety belt. The worker controls the electric hoist, and drives the entire mold to rise through the lifting ring 6. When the mold rises to about 5 centimeters away from the mold rack, the rising is stopped. A wooden wedge is inserted into the clamping seam between the upper die 1 and the lower die 2, and the self-weight of the mold is utilized to complete the mold opening.

[0030] In the present utility model, the positioning and clamping are achieved through the cooperation of the positioning member 4 and the positioning steel balls. The structure is simple, the installation and disassembly operations are convenient, and the clamping efficiency is improved. There is no need to use tools such as hammers to strike, the labor intensity of the worker is low, the required labor cost is low, and the surface of the mold is avoided from being damaged by tools such as hammers. The mold is driven to rise through the lifting ring 6, and the self-weight of the mold is utilized to reduce the force for mold opening. The operation is safe, time-saving and labor-saving, and the mold opening efficiency is improved. Using a wooden wedge for mold opening is not easy to damage the mold, avoiding scratching the inner surfaces of the upper die 1 and the lower die 2 during mold opening, extending the service life of the mold, and improving the processing accuracy of the hull.
