Description

Technical Field

[0001] The utility model relates to the technical field of moulds, and more specifically, to a height-adjustable mould hoisting mechanism. Background Art

[0002] In a single-process product mould, the in-mould pressure plate is embedded inside the mould cavity. The in-mould pressure plate and the mould cavity work in a vertically sliding manner up and down, and the two are in a close sliding fit relationship with a very small sliding fit clearance, and the standard value is 0.03 mm - 0.04 mm. If the in-mould pressure plate is to be hoisted and removed from the mould cavity, the mould hoister must be stressed upward on the same plane.

[0003] When performing mould maintenance, it is necessary to disassemble the in-mould pressure plate before internal maintenance inspection. However, the in-mould pressure plate is designed and developed according to the shape of the product, and the products often have different heights and shapes. As a result, the hoisting threaded holes of the in-mould pressure plate often have height differences and are not on the same horizontal plane, which makes it difficult for mould repair fitters to operate. A large amount of time is wasted in the disassembly process to search for lifting rings with different lengths to try hoisting, wasting time and making it impossible to quickly maintain and repair the inside of the mould. And often during the hoisting process, the mould guide plate is broken, the lifting ring is deformed, and the mould is even lifted together. There is even a risk of falling and injuring people in the air. Summary of the Utility Model

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the present utility model will be described in detail below with reference to the drawings. Obviously, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] Refer to Figure 1, this embodiment provides a highly adjustable mold hoisting mechanism for hoisting the pressure plate 400 in the mold. The highly adjustable mold hoisting mechanism includes a first rod 100 and a second rod 200.

[0026] The first rod 100 is used to connect with the pressure plate and install the second rod 200. The second rod 200 is used to hang the lifting rope of a hoisting machine such as a crane.

[0027] The first rod 100 is a pipe fitting with a wall thickness of 5 mm and a diameter of 35 mm. Along its length direction, a number of jack holes 110 are distributed at intervals on the first rod 100. One end of the first rod 100 is provided with a threaded portion 120.

[0028] In this embodiment, the jack holes 110 are through holes with a diameter of 18 mm and radially penetrate the first rod 100. A number of the jack holes 110 are spaced 25 mm apart in the length direction of the first rod 100 and are distributed in a counterclockwise rotation.

[0029] The second rod 200 can be inserted into the jack holes 110 on the first rod 100.

[0030] The second rod 200 and the first rod 100 can be independently arranged, or can be connected to the first rod 100 through a rope member 300 such as a chain. The length of the rope member 300 should ensure that the second rod 200 can be inserted into any one of the jack holes 110 on the first rod 100 without restriction.

[0031] Refer to Figure 2 , the working principle of the highly adjustable mold hoisting mechanism provided in this embodiment:

[0032] First, connect the four first rods 100 to the hoisting threaded holes on the pressure plate 400 through the threaded portions 120 at their ends; since the hoisting holes on the pressure plate 400 are not completely on the same horizontal plane, according to different heights, insert the second rod 200 into the jack holes 110 at different heights so that the four second rods 200 are approximately in the same horizontal plane; finally, rotate the first rod 100 and perform fine height adjustment through the threaded portion 120 of the first rod 100 so that the four second rods 200 are completely in the same horizontal plane.

[0033] After the hoisting mechanism is installed, hang the lifting rope of the crane on the second rod 200 and hoist the pressure plate 400 through the crane.
