Embodiment 1

[0031] see Figure 1-4 , the deformation compensating device for injection molding machine or die-casting machine of the present invention includes a first base plate 41, a second base plate 42, and an elastic connector 43 arranged between the first base plate 41 and the second base plate 42 The first base plate 41 is connected to the side of the movable template 40 opposite to the mold core, and the second base plate 42 is fixedly connected to the movable mold support 44; the elastic connector 43 includes a 41 and the elastic member 433 between the second base plate 42, and a pre-tightening device, the pre-tightening device is used to connect the elastic member 433 to the first base plate 41 and the first base plate 41 with a certain pre-tightening force. Between the second substrate 42 .

[0032] In this example, if Figure 7 As shown, a cavity for placing the deformation compensation device is formed on the movable mold support 44, and the deformation compensation device ...

Embodiment 2

[0040] see Figure 7-9 , On the basis of Embodiment 1 above, the deformation compensation device further includes a rapid pressurization and decompression device for pressurizing or depressurizing the elastic member 433 . The rapid pressurization and pressure relief device includes a driving device 7 that drives the screw 431 to rotate, and a movable block 437 and a top block 438 that are located between the movable template 40 and the end of the screw 431 and are connected in contact with each other. , the movable block 437 is plugged into the bolt head of the screw rod 431 in a circumferential limit, and the top block 438 is arranged in a groove on the movable template 40 in a circumferential limit. In this embodiment, the top block 438 is rectangular, the movable block 437 is circular, and the surface of the movable template 40 that matches the first base plate 41 is provided with a blind hole, the shape of the blind hole is consistent with the shape of the horizontal proj...

Embodiment 3

[0044] On the basis of the above-mentioned embodiment 1 and embodiment 2, the deformation compensation device for the die-casting machine or the injection molding machine of the present invention also includes being installed under the frame 1 of the die-casting machine or the injection molding machine, for Second deformation compensation device for deformation compensation, see figure 1 Part C in and Figure 5-6 .

[0045] The second deformation compensating device is installed in the gap at the bottom of the frame 1, and includes a pair of guide blocks 51, and the two guide blocks 51 are arranged at intervals along the compression direction of the gap; The opening device is arranged between the two guide blocks, and the expansion device drives the guide block 51 to squeeze to both sides of the notch, that is, to move to both sides of the notch below the frame 1 .

[0046] In this embodiment, the gap between the two guide blocks 51 forms a wedge-shaped cavity; the expansion...

Abstract

The invention discloses a deformation compensation device for an injection molding machine or a die-casting machine. The deformation compensation device is positioned between a movable mold plate and a pushing mechanism and / or between a stationary mold plate and a rack, and comprises a first base plate, a second base plate and an elastic connecting piece, wherein the elastic connecting piece is arranged between the first base plate and the second base plate; the first base plate is fixedly connected with the stationary mold plate or the movable mold plate; the second base plate is correspondingly and fixedly connected with the rack or the pushing mechanism; the elastic connecting piece comprises an elastic piece and a pre-tightening device; the elastic piece is positioned between the first base plate and the second base plate; the pre-tightening device is used for connecting the elastic piece between the first base plate and the second base plate by using certain pre-tightening force. By the adoption of a pre-tightening deformation compensation mechanism, the flexible sealing fit between a movable mold and a stationary mold can be ensured; meanwhile, the effect of material ejection pressure can be overcome, the sealing performance of die assembly is ensured, and the deformation compensation device is convenient to assemble and maintain.

Description

technical field [0001] The invention relates to the technical field of injection molding or die-casting, in particular to a deformation compensating device for a movable mold or a fixed mold of an injection molding machine or a die-casting machine. Background technique [0002] When using injection molding or die-casting technology to produce products, it is first necessary to close the movable mold and the fixed mold to form a product cavity, then inject molten raw materials into the cavity, and shape the product under a certain pressure. During the process of injection of raw materials or pressure molding, due to the action of pressure, the movable mold and the fixed mold will have a certain deformation, which directly leads to the change of the original shape of the cavity, and finally leads to the change of the shape of the injection molding or die-casting product, even It is to produce unqualified products, which seriously affects production efficiency and increases pro...
