For the convenience of understanding, the base body part 210 is installed on the fixed mold plate 120 as an example for description.

[0034] The utility model discloses the technical scheme that the movable mold plate 110 and the fixed mold plate 120 are arranged between the movable mold plate 110 and the fixed mold plate 120 and are arranged outside the placement area of the eccentric mold 300, so that when the movable mold plate 110 and the fixed mold plate 120 mutually close mold, the area outside the eccentric mold 300 has the eccentric auxiliary support device 200 to provide auxiliary support, to guarantee that the movable mold plate 110 and the fixed mold plate 120 are balanced when closing mold, ensure that the deformation is symmetrical, thereby effectively protecting the injection molding machine 100.

[0035] Specifically, the eccentric auxiliary support device 200 comprises a base body 210 and an adjusting part 220 connected with each other, wherein the base body 210 is installed on the movable die plate 110 or the fixed die plate 120 during operation, and the end of the adjusting part 220 away from the base body 210 abuts against the fixed die plate 120 or the movable die plate 110; meanwhile, a length adjusting structure 230 is arranged between the base body 210 and the adjusting part 220, and the relative distance between the base body 210 and the adjusting part 220 is adjusted through the length adjusting structure 230, so that the total length of the eccentric auxiliary support device 200 can be equal to the total length of the eccentric mold 300, thereby ensuring that the movable die plate 110 and the fixed die plate 120 are uniformly stressed when they are closed, and the smooth implementation of the technical scheme of the present application is ensured.

[0036] Among them, the specific structure of the length adjusting structure has many kinds, in one embodiment, referring to the attached Figures 2-3 The length adjusting structure comprises a first threaded hole 231 arranged on the base body 210 and a first threaded column 232 arranged on the adjusting part 220, and the first threaded column 232 is threadedly connected with the first threaded hole 231.

[0037] Further, the first threaded column 232 is threadedly connected with a locking nut 233, and the locking nut 233 is used to abut against the base body 210. In this way, after the first threaded column 232 and the first threaded hole 231 are adjusted to the appropriate position, in order to lock the adjusting part 220 on the base body 210, the locking nut 233 can be rotated, and the locking nut 233 and the base body 210 are tightly abutted against each other, thereby preventing the adjusting part 220 from rotating under stress and affecting the relative distance between the base body 210 and the adjusting part 220.

[0038] As a preferred scheme of the above-mentioned embodiment, the end of the adjusting part 220 away from the base body 210 is provided with a stacking part 240, and the adjusting part 220 abuts against the fixed die plate 120 or the movable die plate 110 through the stacking part 240. In this way, considering that the adjustment range of the total length of the eccentric auxiliary support device 200 is limited and the efficiency is low by only rotating the first threaded column 232 and the first threaded hole 231, the large-range adjustment can be realized by directly increasing the stacking part 240, thereby improving the total length adjustment efficiency.

[0039] Among them, the specific structure of the length adjusting structure has many kinds;

[0041] In another embodiment, reference is made to the accompanying drawings Figure 3 The superposition part 240 comprises a second superposition member 244 and a plurality of superposition rings 245; the second superposition member 244 is provided with a fourth threaded column 246, and the end of the adjustment part 220 facing the superposition part 240 is provided with a fourth threaded hole 222; the fourth threaded column 246 is threaded connected with the fourth threaded hole 222; wherein the plurality of superposition rings 245 can be mutually superimposed and sleeved on the fourth threaded column 246, so that the plurality of superposition rings 245 are tightly fixed between the second superposition member 244 and the adjustment part 220. In this way, the plurality of superposition rings 245 are mutually layered and sleeved on the fourth threaded column 246, and then the fourth threaded column 246 and the fourth threaded hole 222 are tightened to tightly fix the plurality of superposition rings 245 between the second superposition member 244 and the adjustment part 220, so as to realize the adjustment of the total length of the eccentric auxiliary support device 200 in a larger range. At the same time, since the superposition ring 245 in this embodiment is directly sleeved on the fourth threaded column 246, the plurality of superposition rings 245 can be added more quickly, so as to further improve the total length adjustment efficiency.
