[0002] Injection molding machine rack as the core support structure of injection molding machine, its stability and durability are directly related to the overall performance and processing precision of injection molding machine.In the injection molding process, the rack needs to withstand the huge pressure and impact force from injection mold, which requires the rack to have good anti-deformation ability.However, the traditional injection molding machine rack design often has the problem of easy deformation.

[0003] Traditional rack usually adopts simple welding or bolt connection mode, which often leads to relative displacement or deformation between rack plates when subjected to large pressure and impact force.Especially during long-term use, due to material fatigue and stress concentration, the deformation problem of the rack is more prominent.Once the rack deforms, it will not only affect the processing precision and stability of the injection molding machine, but also may cause damage to the injection mold, and even cause safety accidents.In addition, the traditional rack often lacks sufficient rigidity and strength in structural design, and cannot effectively resist various forces and moments generated during injection molding.Especially on some large injection molding machines, due to the increase of injection pressure and mold weight, the deformation problem of the rack is more serious.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-6 As shown, this utility model provides a deformation-resistant injection molding machine frame. Through structural design, the overall rigidity and stability of the frame are enhanced, effectively preventing deformation problems.

[0024] The frame mainly consists of a top plate 1, a bottom plate 2, a front plate 3, a rear plate 4, and two side panels 5. The two side panels 5 are connected to the front plate 3 and the rear plate 4 by welding or bolting, forming a closed hollow frame structure. To enhance the connection strength between the side panels 5 and the front and rear plates and to prevent deformation, extensions 7 are designed at both ends of the side panels 5. These extensions 7 are close to the outer side of the front plate 3 and the rear plate 4 and are secured with fasteners such as screws. Limiting protrusions 13 are machined at both ends of the front plate 3 and the rear plate 4. The shape and size of these limiting protrusions 13 match the extensions 7 of the side panels 5 to ensure that the extensions 7 can be accurately inserted and fixed.

[0025] The extension 7 is specially provided with a limiting groove 8. At the same time, the limiting protrusion 13 is also provided with a protrusion 14 that matches the limiting groove 8 on the extension 7. These limiting grooves 8 match the corresponding protrusions 14 on the front end plate 3 and the rear end plate 4 to form a snap-fit ​​fixing structure, which further enhances the stability and deformation resistance of the connection.

[0026] Between the two side panels 5, several springs 6 are evenly distributed. One end of each spring 6 is connected to the inside of one side panel 5 and the other end is connected to the inside of the other side panel 5, providing inward tension. Through the squeezing action of the extension 7, the side panels 5 are more tightly attached to and fixed to the front end plate 3 and the rear end plate 4, effectively resisting lateral deformation caused by external pressure.

[0027] The spring members 6 are arranged not only below the bottom plate 2 but also below the top plate 1 in the embodiment, forming two layers of tension systems. The spring members 6 are evenly distributed along the direction from the front end plate 3 to the rear end plate 4, effectively dispersing and balancing the stress inside the rack, and further improving the anti-deformation capability.

[0028] In order to install the bottom plate 2, the first clamping grooves 11 are arranged on the opposite surfaces of the front end plate 3 and the rear end plate 4, and the second clamping grooves 12 are arranged on the opposite surfaces of the two side plates 5. At this time, the bottom plate 2 is sealingly installed in the hollow region surrounded by the clamping grooves. In order to further fix the position of the bottom plate 2, a plurality of protrusions are arranged as clamping blocks 15 in the first clamping grooves 11 and the second clamping grooves 12, which are matched with the limiting clamping grooves 16 opened at the bottom of the bottom plate 2, ensuring the stable installation of the bottom plate 2 in the rack.

[0029] The top plate 1 is installed above the bottom plate 2, and the bottom of the top plate 1 is designed with a top plate mounting groove 9, which is shaped and sized to cover and envelope the top edges of the front end plate 3, the rear end plate 4 and the two side plates 5, thereby forming a complete protection structure.

[0030] In order to facilitate maintenance and operation, the side plates 5 are also designed with hole positions 10 leading to the upper side of the bottom plate 2, and the hole positions 10 are installed with outwardly open door leaves 17, so that the operating personnel can conveniently enter the inside of the rack for inspection or repair work.

[0031] Compared with the prior art, the rack of the injection molding machine provided by the technical scheme is assembled through a specific connection mode between the plates, ensuring the close fit between the plates. Even if subjected to a large pressure and impact force, the plates are not prone to relative displacement or deformation, thereby effectively maintaining the overall structural stability of the rack. The spring members 6 are added between the two side plates 5 to provide inward pulling force for the rack, maintaining the overall shape and structural integrity of the rack, and achieving the anti-deformation effect.

[0032] It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application, and any reference signs in the claims should not be regarded as limiting the claims.
