Description

Technical Field

[0001] This utility model relates to the field of injection mold hoisting technology, and in particular to a hoisting device for injection molds. Background Technology

[0002] Injection molds typically consist of a front mold and a rear mold. During hoisting, lifting rings are usually attached to the injection mold, and hoisting is accomplished using slings. Of course, the front mold and rear mold can also be hoisted separately.

[0003] Whether lifting the entire mold or lifting it in sections, the lifting operation must meet the requirements of vertical lifting. In particular, when installing injection molds onto the injection molding machine, large tilt angles are not allowed to avoid unnecessary collisions during the lifting process. Therefore, the extension line of the mold's center of gravity must be collinear with the direction of the slings.

[0004] However, due to the structural design of the injection mold, there are unavoidable important components at the position of the extended line of the center of gravity, which are prone to interference with the lifting ring. Installing the lifting ring in other positions would prevent the extended line of the mold's center of gravity from being collinear with the direction of the lifting sling, creating a risk during lifting.

[0005] Therefore, a new type of lifting formwork device is needed to solve the above problems. Utility Model Content

[0006] The summary section of this utility model is intended to briefly introduce the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solution, nor is it intended to limit the scope of the claimed technical solution.

[0007] This utility model provides a mold lifting device for injection molds to solve the technical problems mentioned in the background section above.

[0008] The present invention relates to a lifting device for injection molds, comprising a rear mold side lifting plate, a front mold side lifting plate, and lifting rings; The rear mold side lifting plate has an overall lifting hole and a rear mold lifting hole. When lifting the rear mold, the lifting ring is installed into the rear mold lifting hole, and the rear mold side lifting plate is connected to the rear mold at intervals; wherein, the rear mold lifting hole coincides with the extension line of the center of gravity of the rear mold; The front mold side lifting plate has a front mold lifting hole. When lifting the front mold, the lifting ring is installed into the front mold lifting hole, and the front mold side lifting plate is connected to the front mold at intervals; wherein, the front mold lifting hole coincides with the extension line of the center of gravity of the rear mold; When hoisting the injection mold, the lifting ring is installed into the integral lifting hole, which coincides with the extension line of the center of gravity of the injection mold.

[0009] Optionally, the rear mold side lifting plate is also provided with multiple rear mold connection holes, which are evenly arranged around the rear mold lifting hole.

[0010] Optionally, multiple connecting bolts pass through multiple rear mold connecting holes in a one-to-one correspondence, and a portion of the multiple connecting bolts is threadedly connected to the rear mold.

[0011] Optionally, each connecting bolt on the rear mold side lifting plate is fitted with a support column, and in the assembled state, both ends of the support column are tightly engaged with the rear mold side lifting plate and the rear mold.

[0012] Optionally, the length of the support column is set to be greater than the height of the important component.

[0013] Optionally, the front mold side lifting plate is also provided with multiple front mold connection holes, which are evenly arranged around the front mold lifting hole.

[0014] Optionally, multiple connecting bolts pass through multiple front mold connecting holes in a one-to-one correspondence, and a portion of the multiple connecting bolts is threadedly connected to the front mold.

[0018] The above embodiments of this utility model have the following beneficial effects: When hoisting the rear formwork, the hoisting hole of the rear formwork coincides with the extension line of the center of gravity of the rear formwork, which makes the sling connecting the lifting ring coincide with the extension line of the center of gravity of the rear formwork, so that the rear formwork can be hoisted vertically. When hoisting the front formwork, the hoisting hole of the front formwork coincides with the extension line of the center of gravity of the front formwork, which makes the sling connecting the lifting ring coincide with the extension line of the center of gravity of the front formwork, so that the front formwork can be hoisted vertically. When hoisting the injection mold, the overall hoisting hole coincides with the extension line of the injection mold's center of gravity, which in turn causes the sling connecting the lifting ring to coincide with the extension line of the injection mold's center of gravity, allowing the injection mold to be hoisted vertically.

Furthermore, the terms "installed," "connected," and "linked" should be interpreted broadly; for example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] Please refer to the following first. Figure 1 and Figure 2 The lifting device for injection molds of this utility model includes a rear mold side lifting plate 3, a front mold side lifting plate 4, and a lifting ring 7.

[0028] When hoisting the rear mold 2, a lifting ring 7 is installed at the upper end of the rear mold side lifting plate 3, so that the sling connecting the lifting ring 7 coincides with the extension line of the rear mold's center of gravity. The lower end face of the rear mold side lifting plate 3 is connected to the rear mold 2 at intervals, thereby avoiding interference with the unavoidable important components 8 on the rear mold 2.

[0029] Specifically, please refer to Figures 1 to 3 A rear mold lifting hole 31 is provided in the middle of the rear mold side lifting plate 3. This rear mold lifting hole 31 is used to install the lifting ring 7 when lifting the rear mold. The rear mold side lifting plate 3 also has four rear mold connecting holes 33, which are evenly arranged around the rear mold lifting hole 31. Four connecting bolts 5 pass through the four rear mold connecting holes 33 one by one, and a portion of the four connecting bolts 5 is threaded to the rear mold 2, realizing the phased connection between the rear mold side lifting plate 3 and the rear mold 2.

[0030] When hoisting the rear mold 2, the axis of the aforementioned rear mold hoisting hole 31 coincides with the extended line of the rear mold 2's center of gravity, so that the sling connecting the lifting ring 7 also coincides with the extended line of the rear mold's center of gravity. Therefore, those skilled in the art can adjust the position of the rear mold hoisting hole 31 according to the center of gravity of different rear molds. This allows for the selection of a suitable rear mold side hoisting plate 3 for different rear molds.

[0031] In addition, the four rear mold connection holes 33 can be distributed according to the important components that cannot be avoided on the rear mold 2, thereby avoiding interference between the connecting bolts 5 and the important components.

[0032] The rear mold side lifting plate 3 is connected to the rear mold 2 at intervals, so that there is a certain height between the rear mold side lifting plate 3 and the rear mold 2, which can be used to accommodate the above-mentioned important components and avoid interference between the lower end of the rear mold side lifting plate 3 and the important components.

[0033] Furthermore, the aforementioned rear mold side lifting plate 3 may also include four support columns 6, each support column 6 being fitted onto a connecting bolt 5. During lifting, the two ends of the support column 6 are tightly engaged with the bottom of the rear mold side lifting plate 3 and the rear mold 2, thereby reducing the bending moment and shear force on the connecting bolt 5.

[0034] In addition, the length of the support column 6 can be set to be greater than the height of the important component 8, so that when the connecting bolt 5 is tightened, the support column 6 can play a limiting and protective role, preventing the rear mold side lifting plate 3 from squeezing the important component 8.

[0035] It should be noted that although the attached diagram is illustrated using four rear mold connection holes 33 and four connecting bolts 5 as an example, those skilled in the art can adjust the number of rear mold connection holes 33 and connecting bolts 5 according to the actual situation.

[0036] In this way, without interfering with the important component 8, the lifting plate 3 on the rear mold side can be aligned with the extension line of the center of gravity of the rear mold 2, so that the rear mold 2 can be lifted vertically, thus improving the reliability of the lifting device.

[0037] When hoisting the front mold, a lifting ring 7 is installed on the upper end of the front mold side lifting plate 4, so that the sling connecting the lifting ring 7 coincides with the extension line of the center of gravity of the front mold 1. The lower end face of the front mold side lifting plate 4 is connected to the front mold at intervals, thereby avoiding interference with the unavoidable important components 8 on the front mold 1.

[0038] Please see Figure 1 , Figure 2 , Figure 4 and Figure 6A front mold lifting hole 41 is provided in the middle of the front mold side lifting plate 4. This front mold lifting hole 41 is used to install the lifting ring 7 when lifting the front mold 1. The aforementioned front mold side lifting plate 4 has two front mold connecting holes 42, which are evenly arranged around the front mold lifting hole 41. Two connecting bolts 5 pass through the two front mold connecting holes 42 one-to-one, and a portion of the two connecting bolts 5 is threadedly connected to the front mold 1, realizing the alternating connection between the front mold side lifting plate 4 and the front mold 1.

[0039] When hoisting the front mold, the axis of the aforementioned front mold hoisting hole 41 coincides with the extended line of the center of gravity of the front mold 1, so that the sling connecting the lifting ring 7 also coincides with the extended line of the center of gravity of the front mold 1. Therefore, those skilled in the art can adjust the position of the front mold hoisting hole 41 according to the center of gravity of different front molds 1. Thus, a suitable front mold side hoisting plate 4 can be selected for different front molds.

[0040] In addition, the two front mold connection holes 42 can be distributed according to the important components 8 that cannot be avoided on the front mold 1, so as to avoid interference between the connecting bolts 5 and the important components 8.

[0041] The front mold side lifting plate 4 is connected to the front mold at intervals, so that there is a certain height between the front mold side lifting plate 4 and the front mold, which can be used to accommodate the important components 8 and avoid interference between the lower end of the front mold side lifting plate 4 and the important components 8.

[0042] Furthermore, the aforementioned front mold side lifting plate 4 may also include two support columns 6, each support column 6 being fitted onto a connecting bolt 5. During lifting, the two ends of the support column 6 are tightly engaged with the bottom of the front mold side lifting plate 4 and the front mold, thereby reducing the bending moment and shear force on the connecting bolt 5.

[0043] In addition, the length of the support column 6 can be set to be greater than the height of the important component 8, so that when the connecting bolt 5 is tightened, the support column 6 can play a limiting and protective role, preventing the front mold side lifting plate 4 from squeezing the important component 8.

[0044] It should be noted that although the attached diagram is illustrated using two rear mold connecting holes 33 and two connecting bolts 5 as an example, those skilled in the art can adjust the number of front mold connecting holes 42 and connecting bolts 5 according to the actual situation.

[0045] In this way, without interfering with the important components 8, the lifting plate 4 on the front mold side can be aligned with the extension line of the center of gravity of the front mold 1, so that the front mold 1 can be lifted vertically, thus improving the reliability of the lifting device.

[0046] The aforementioned rear mold lifting hole 31 and front mold lifting hole 41 can be countersunk holes, and the connecting bolt 5 can be a cup head bolt.

[0047] Please seeFigure 1 , Figure 2 and Figure 5 During the overall hoisting, in accordance with the technical plan of hoisting the rear mold 2 and the front mold 1 separately, the rear mold side hoisting plate 3 and the front mold side hoisting plate 4 are connected to the rear mold 2 and the front mold 1 in a spaced manner.

[0048] The aforementioned rear mold side lifting plate 3 is also provided with an integral lifting hole 32. During integral lifting, the axis of the integral lifting hole 32 coincides with the extension line of the center of gravity of the injection mold, so that the lifting cable connecting the lifting ring 7 also coincides with the extension line of the center of gravity of the injection mold. In this way, the injection mold can be lifted vertically, improving the reliability of the mold lifting device.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
