Description

Technical Field

[0001] The utility model relates to an insert quick-disassembly structure, in particular to a GMT mould insert quick-disassembly structure. Background Art

[0002] Generally, OEMs will have high-end and low-end models. In this regard, GMT Mold may have products in various states when developing molds, so it is necessary to design interchangeable inserts when developing molds.

[0003] The inserts in the GMT mold play a vital role in the mold manufacturing and molding process. First, the inserts can facilitate the modification of the mold, and the mold often needs to be modified according to the changes in the product design. By pre-setting the inserts in the mold, when the mold needs to be modified, only the inserts need to be replaced or adjusted without large-scale modifications to the entire mold, which greatly reduces the time and cost of modifying the mold.

[0004] For example, general OEMs will have high-end and low-end models, and there may be some differences in details between the high-end and low-end models. Products that only need to change some structures or details can be achieved by replacing or adjusting the corresponding inserts without redesigning and manufacturing the entire mold.

[0005] Since the insert cannot be fixed by drilling a screw countersunk hole on the surface, in the prior art, the insert needs to be fixed by using some quick-release structures such as buckle structures or clamps, but there is still the problem of unchanged replacement. Utility Model Content

[0006] The purpose of the utility model is to provide a GMT mold insert quick-release structure. Through a detachable limiter and ejector, the thrust can be converted into an ejection force along the axis direction of the vertical rod by utilizing the cooperation of two inclined surfaces, so that the insert can be easily ejected. In addition, the insert can also be conveniently fixed by utilizing a push-pull limiter.

[0036] A GMT mold insert quick-release structure, such as Figure 1 As shown, it includes a mold body 2 and an insert 1 detachably arranged on the mold body 2, and the quick-release structure also includes a detachable limiting member 3 and a detachable ejector 4, as shown in FIG. Figure 2 As shown, the insert 1 includes a main body 1-1 and a vertical rod 1-2 connected to the main body 1-1 at one end, the ejector 4 includes a push rod matched with the vertical rod 1-2, a first inclined surface 4-1 is provided on the push rod, and a second inclined surface 1-2-1 matched with the first inclined surface 4-1 is provided at the bottom of the vertical rod 1-2, and the vertical rod 1-2 and the axis are perpendicular to the axis of the push rod, and a limit member 3 is provided above the ejector 4 for fixing the vertical rod 1-2.

[0037] Through the detachable limiter 3 and ejector 4, the thrust can be converted into an ejection force along the axis of the vertical rod 1-2 by utilizing the cooperation of the two inclined surfaces, so that the insert 1 can be easily ejected. In addition, the push-pull limiter 3 can also be used to conveniently fix the insert 1.

[0038] In almost all embodiments, there are two vertical rods 1-2 on the insert 1, the number of ejector rods on the ejector 4 is consistent with the number of vertical rods 1-2 and corresponds one to one, and the first inclined surface 4-1 on any ejector rod cooperates with the second inclined surface 1-2-1 on the corresponding vertical rod 1-2.

[0039] The insert 1 is provided with two vertical rods 1-2, so that it can cooperate with two push rods to apply force synchronously from both sides and form two-point support to avoid the poor stability caused by a single vertical rod 1-2.

[0040] like Figure 5 As shown, in this embodiment, the ejector 4 further includes a first grabbing strip 4-2, and two ejector rods are connected to the same side of both ends of the first grabbing strip 4-2. The ejector 4 further includes the first grabbing strip 4-2 to facilitate manual or external mechanical grabbing or pushing, thereby improving convenience and stability.

[0041] Generally, the two push rods are arranged in parallel, so as not to generate a lateral force parallel to the axis of the first grabbing bar 4 - 2 , thereby improving stability.

[0042] like Figure 3 and Figure 4 As shown, the limiting member 3 includes a second grabbing bar 3-2 and two limiting rods 3-1. The two limiting rods 3-1 are connected to the same side of both ends of the second grabbing bar 3-2. Similarly, the second grabbing bar 3-2 is convenient for manual or external machinery to grab or push in, thereby improving convenience and stability.

[0043] In addition, two fan-shaped notches are provided at the end of the limit rod 3-1, and the two fan-shaped notches are arranged axially symmetrically. The fan-shaped notches are provided at the end of the limit rod 3-1. Based on the fan-shaped notches, two forces in opposite directions can be formed from the opposing rod 1-2, thereby improving the stability during the limit. Generally, the two limit rods 3-1 are arranged in parallel.

[0044] In this embodiment, the central angle of the fan-shaped notch is 90 degrees, and both ends of the arc of the fan are perpendicular to the edge of the limiting rod, so that it can be easily inserted into and contact the vertical rod 1-2, thereby forming a limiting support.

[0045] The distance between the two limit rods 3 - 1 is greater than the distance between the two top rods.

[0046] The mold body 2 is provided with a supporting portion that cooperates with the limiting member 3 , and the supporting portion and the limiting member 3 are respectively located on two sides of the insert 1 .

[0047] Specifically, during use, under normal working conditions, the ejector 4 is taken out and the insert is fixed by the limiting member 3. When replacement is required, the limiting member 3 is taken out and the ejector 4 is pushed forward to eject the insert 1, so that the insert 1 can be quickly replaced.
