[0002] In the field of industrial production, many large molds are often used. At this time, the large molds need to be hoisted and moved. The mold includes a mold core and a mold core. The mold core and the mold core are generally assembled together. When the design needs to be changed or maintenance is required, the mold core is generally separated from the mold core. At this time, the mold core needs to be hoisted and moved.

[0003] The patent document with patent announcement number: CN117262978A discloses a lifting bracket for quickly installing a mold, including a support plate, a receiving plate fixedly arranged on the support plate, a mounting plate slidably arranged on the receiving plate, a telescopic component arranged on the receiving plate, the telescopic component is connected to the mounting plate and can drive the mounting plate to move relative to the receiving plate; an extension component is arranged on the mounting plate and connected to the receiving plate, the extension component includes two groups of extension parts symmetrically slidably arranged along the width direction of the mounting plate, when the mounting plate moves relative to the receiving plate, the extension component can drive the two groups of extension parts to move closer to or away from each other; a support component is arranged on the receiving plate, connecting the support plate and the receiving plate, including a sleeve plate arranged on the receiving plate, an unlocking component and an extension part are arranged on the sleeve plate, the unlocking component and the extension part are connected, the extension part is connected to the telescopic component, and when the unlocking component is triggered, the mounting plate can drive the extension part to slide relative to the sleeve plate.

[0004] The above solution is for hoisting molds with hoisting holes on the surface. However, since the inner surface of many products is smooth, the surface of the mold core is also closed. In addition, the mold core of a large plastic mold is heavy and cannot be moved by manpower. It can only be hoisted by machine. Currently, there are generally the following ways to hoist a closed mold core:

[0005] The mold core is hoisted by magnets, but it is easy to damage the mold core during hoisting;

[0006] The mold core and mold core are designed as an integrated whole. The mold core is directly hoisted during hoisting, but this will lead to waste of materials during modeling. The electrodes for mold EDM processing need to be disassembled very high, which is time-consuming and costly. Utility Model Content

[0036] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] Embodiment 1:

[0038] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 As shown, a hidden lifting mechanism for a large plastic mold is used to lift a mold core 2. The mold core 2 is detachably connected to the mold core 1. The lifting mechanism includes an insert 3, a screw 4 and a mold hanging member 5.

[0039] like Figure 2 , Figure 4 , Figure 5 As shown, a mounting groove 11 is provided on the surface of the mold core 1, the mold core 2 matches the size of the mounting groove 11, and the depth of the mounting groove 11 is less than the height of the mold core 2. After the mold core 2 is installed in the mounting groove 11, the top surface height of the mold core 2 is higher than the top surface height of the mold core 1.

[0040] like Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, an embedded groove 22 is opened on the surface of the mold core 2, and the size of the insert 3 matches the size of the embedded groove 22, and the mold core 1 and the mold core 2 are respectively vertically opened with a mounting hole 12 and a positioning hole 21 at the position corresponding to the embedded groove 22, and the axis of the mounting hole 12, the positioning hole 21 and the embedded groove 22 is the same, and the three are connected.

[0041] In this embodiment, the diameter of the embedded groove 22 is larger than the diameter of the mounting through hole 12 , and the diameter of the mounting through hole 12 is larger than the diameter of the positioning hole 21 .

[0042] When there is no need to lift and transport the core mold 2, the insert 3 is embedded in the embedded groove 22 from top to bottom, and the screw 4 passes through the installation through hole 12 and the positioning hole 21 from bottom to top in sequence, and the upper end of the screw 4 is inserted into the bottom of the insert 3. At this time, the insert 3 can be pressed and the screw 4 can be rotated so that the upper end of the screw 4 is threadedly connected to the insert 3. At this time, the surface of the core mold 2 is closed and the modeling operation can be carried out.

[0043] like Fig. 9 As shown, an operating groove 41 is provided at the bottom end of the screw 4 . The operating groove 41 is a polygonal structure, which makes it easy to insert a tool into the operating groove 41 and then rotate the screw 4 .

[0044] When the mold core 2 needs to be hoisted and transported, after removing the insert 3 and the screw 4, use the hoisting mold 5 for hoisting. The hoisting mold 5 includes an upper hanging ring portion 51 and a lower threaded portion 52, and the inner wall of the positioning hole 21 is provided with an internal threaded surface. After the threaded portion 52 is inserted into the positioning hole 21 from top to bottom and the hoisting mold 5 is rotated, the threaded portion 52 is threadedly connected with the internal threaded surface of the inner wall of the positioning hole 21. At this time, the hanging ring portion 51 can be hung by the connecting assembly, and the mold core 2 can be hoisted.

[0045] In this embodiment, the eye portion 51 and the threaded portion 52 are an integrated structure, which has a stronger structural integrity.

[0046] This solution improves the mold core 2 to achieve the hoisting operation of the heavy weight mold core 2 without affecting the normal casting operation of the injection molding machine. When the mold core 2 needs to be transported and hoisted, the mold core 2 can be hoisted by installing the hanging module 5. It is highly efficient, does not require manual transportation, will not damage the mold core 2, and is relatively safe.

[0047] Embodiment 2:

[0048] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 As shown, a large plastic mold hidden lifting mechanism is used to lift the mold core 2, the mold core 2 is detachably connected to the mold core 1, and the lifting mechanism includes an insert 3, a screw 4 and a hanging mold 5. Compared with the first embodiment, the difference of this embodiment is:

[0049] like Figure 8 , Fig. 9 As shown, the inner wall of the embedded groove 22 is provided with a step 23, and the surface of the insert 3 is provided with a step groove 31 matching the step 23. In this way, after the insert 3 is embedded in the embedded groove 22, there is no need to press the insert 3 when the screw 4 is threadedly connected with the insert 3. The insert 3 will not rotate due to the clamping of the step 23 and the step groove 31, which is more convenient to use.
