[0024] like Figures 1-5 As shown, this utility model provides an anti-deformation support structure for injection molds, including a mold body 1 and a mounting base 2. A linear telescopic component 3 is installed at the top of the mounting base 2. The head of the linear telescopic component 3 is connected to the four bottom corners of the mold body 1. A connecting plate 4 is fixedly connected between the telescopic parts of the linear telescopic component 3. The top of the connecting plate 4 is connected to the middle part of the bottom of the mold body 1 through a support column 5. An elastic buffer component 6 is installed between the bottom end of the support column 5 and the mounting base 2.

[0025] When the mold body 1 is subjected to mechanical stress, the support column 5 and the telescopic part of the linear telescopic component 3 are simultaneously moved linearly downward (the linear telescopic component 3 can maintain the telescopic part to move linearly downward), thereby extruding the elastic buffer component 6 between the connecting plate 4 and the mounting base 2, and the elastic buffer component 6 can effectively absorb and disperse the stress, avoid the stress concentration from being transmitted to the local area of the mold body 1, thereby reducing the risk of deformation of the mold body 1, and the support column 5 and the support part of the four linear telescopic components 3 are connected with the mold body 1, the support force can be uniformly distributed in different positions of the mold body 1, and the local stress concentration can also be effectively avoided, thereby further reducing the deformation of the mold caused by uneven stress, and the elastic buffer component 6 is a spring, a rubber pad or a hydraulic buffer.

[0026] Spring: capable of absorbing mechanical stress through elastic deformation and restoring to original state when stress is released, suitable for occasions requiring large buffer stroke.

[0027] Rubber pad: good elasticity and damping characteristics, capable of absorbing high-frequency vibration and impact, and dispersing stress, suitable for small and medium-sized molds.

[0028] Hydraulic buffer: capable of providing smooth and controllable buffering effect by flowing and compressing hydraulic oil, suitable for high-load and high-precision occasions.

[0029] The specific structure of the linear telescopic component 3 is as follows: the linear telescopic component 3 comprises an upper open slot seat 301 around the top end of the mounting base 2, guide rails 302 for sliding blocks 303 to slide are fixedly connected to both sides of the inside of the upper open slot seat 301, a lifting plate 304 is fixedly connected between the sliding blocks 303, the head of the lifting plate 304 is connected with the bottom of the mold body 1 through a vertical rod 305, and the connecting plate 4 is installed on the outer side wall of the vertical rod 305.

[0030] That is, when the mold body 1 moves up and down, the vertical rod 305 moves up and down, the vertical rod 305 drives the sliding blocks 303 to move up and down, and the sliding blocks 303 slide up and down along the guide rails 302 to maintain the vertical rod 305 to move up and down linearly.

[0031] In addition, the mold body 1, the vertical rod 305 and the support column 5 are designed to be detachably connected, so that when the support structure is damaged, it can be replaced and repaired, or when the mold body 1 is damaged, the support structure can be installed on other molds for use.

[0032] The specific structure of the detachable connection is as follows: the bottom end of the mold body 1 is fixedly connected with a connecting block 7, the top end of the vertical rod 305 and the support column 5 is fixedly connected with a connecting slot 8 for the connecting block 7 to insert, the side end of the connecting block 7 is provided with a through hole 9, and the side end of the connecting block 7 is provided with a threaded hole 10 corresponding to the through hole 9.

[0033] The connecting block 7 below the mold body 1 is inserted into the connecting groove seat 8 at the top end of the vertical rod 305 and the supporting column 5 for positioning, after the insertion, the screw hole 10 on the connecting block 7 and the through hole 9 on the connecting groove seat 8 are aligned, and then the screw is screwed through the through hole 9 on the connecting groove seat 8 and installed into the screw hole 10 on the connecting block 7 in a clockwise direction, thereby completing the fixation of the connecting block 7 and the connecting groove seat 8, and the assembly between the injection mold and the supporting structure, the positioning and then the fixation installation mode provides a clear reference point for installation, and the operator can quickly find the installation position, thereby reducing the time for repeated adjustment and improving the installation efficiency, on the contrary, the screw is removed, and then the connecting block 7 is pulled out of the connecting groove seat 8, thereby completing the disassembly between the injection mold and the supporting structure, and the disassembly and assembly are relatively convenient.

[0034] Further, the connecting groove seat 8 and the connecting block 7 are made of a heat-conducting material (such as an aluminum alloy or a copper alloy), which is used for quickly conducting the heat of the mold body 1, and the quick heat conduction can reduce the temperature gradient of the mold in a local area, reduce the thermal stress concentration caused by the uneven thermal expansion, thereby preventing the deformation or cracking of the mold and prolonging the service life of the mold.

[0035] The elastic buffer component 6 is detachably connected with the connecting plate 4 and the mounting seat 2 through the screw (the elastic buffer component 6 will gradually lose the elastic performance due to the repeated deformation in long-term use, and finally cause damage), and the detachable connection makes the installation and disassembly of the elastic buffer component 6 more convenient, and the operator can quickly complete the replacement or maintenance.

[0036] The above is only a preferred embodiment of the present application, and does not limit the present application in any form; any ordinary technical personnel in the industry can implement the present application according to the above description and the drawings; however, any equivalent changes, modifications and evolution of the above disclosed technical content without departing from the technical scheme of the present application are equivalent embodiments of the present application; meanwhile, any equivalent changes, modifications and evolution of the above embodiments according to the essential technology of the present application are still within the protection scope of the technical scheme of the present application.
