Description

Technical Field

[0001] This utility model relates to the field of injection molding machines, and in particular to a split-type mold clamping machine body. Background Technology

[0002] The mold clamping body of the injection molding machine is mainly used to support the weight of the mold clamping components, which include a fixed mold plate and a moving mold plate. The overall mold clamping body is a rectangular frame structure, consisting of long support beams on both sides and several shorter connecting beams connecting the support beams. A head plate support plate is welded and fixed to one end of each of the two support beams. In the above-mentioned components of the mold clamping body, the head plate support plate is used to install and support the fixed mold plate, and the support beams are used to support the moving moving mold plate.

[0003] The composition of existing support beams can be referenced. Figure 2 As shown, the structure includes a base plate 1a arranged parallel to each other, side support plates 3a vertically welded to both sides of the base plates, and a support upright plate 2a welded between the base plates 1a. This support beam structure, formed by welding multiple plates, is not only time-consuming and difficult to weld, but also more prone to deformation. Individually formed beams are susceptible to twisting and other deformations. Therefore, existing fuselage structures require the support beams and connecting beams to be welded together before continuous welding to ensure sufficient strength to resist deformation caused by continuous welding stress. For details, please refer to... Figure 1 As shown, in order to ensure strength, several connecting blocks 4a need to be welded horizontally at intervals on the supporting plate 2a, and a reinforcing beam 5a also needs to be welded. The reinforcing beam 5a is simultaneously welded to the connecting beam, the head plate support plate and the connecting blocks 4a, which not only makes production difficult, but also makes transportation and storage inconvenient. Utility Model Content

[0004] This invention addresses the shortcomings of existing mold clamping machine bodies, such as high production difficulty and inconvenient transportation and storage, by providing a split-type mold clamping machine body that reduces production difficulty while facilitating transportation and storage.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A split-type mold clamping machine body includes two parallel support beams, at least two connecting beams vertically connected between the support beams, and two head plate support plates welded to one end of the support beams on opposite sides. The support beams include an integral support body, and the head plate support plates are welded to one end of the support body on opposite sides. The connecting beams are detachably and fixedly connected to the support beams.

[0007] By adopting the above solution, the original support beam, in which the upper and lower bottom plates and vertical plates were welded and fixed, is replaced with an integrally formed structure, which saves a lot of welding work and reduces the difficulty of production. Since the main support body is integrally formed, its strength is significantly improved. Even if it is detachably fixedly connected to the connecting beam, it can still meet the support requirements during the movement of the moving template. Therefore, the original method of welding the support beam and connecting beam is replaced with a detachable fixed connection. The split mold-closing machine body is transported and stored in a split form and assembled when in use. This not only reduces the difficulty of production, but also improves the convenience of transportation and storage.

[0008] Preferably, auxiliary support plates are welded to one or both sides of the support body to increase the load-bearing capacity of the support body, and the auxiliary support plates are also welded and fixed to the upper and lower ends of the support body.

[0009] Preferably, the auxiliary support plate is an integral plate extending along the length of the support body or a number of separate plates spaced apart along the length of the support body.

[0010] By adopting the above scheme, the welding of the auxiliary support plate can further improve the load-bearing capacity of the entire support beam, which can be used for the load-bearing of medium and large models.

[0011] Preferably, a connecting plate is welded between the head plate support plate and the support body to eliminate the gap between the sliding foot of the moving template and the head plate support plate.

[0012] By adopting the above solution, in actual manufacturing, a connecting plate of appropriate thickness can be selected according to different machine models to eliminate the gap between the sliding foot of the moving template and the head plate support plate.

[0013] Preferably, a connecting block with mounting holes is welded onto the support beam, and the connecting beam is provided with assembly holes corresponding to the mounting holes. The connecting beam and the connecting block are detachably and fixedly connected by bolts and nuts.

[0014] Using the above method, after the bolts pass through the assembly holes and mounting holes in sequence, they are tightened with nuts to achieve a fixed connection between the connecting beam and the support beam.

[0015] Preferably, a steel strip mounting surface is provided on the upper end face of the support body, and a liquid collection tank for receiving oil and water is milled on the outer periphery of the steel strip mounting surface on the upper end face of the support body, which is lower than the steel strip mounting surface.

[0016] By adopting the above solution, the addition of a liquid collection tank creates a low-lying area, allowing oil and water falling onto the upper surface of the support body to be quickly guided into the collection tank. This prevents the oil and water from seeping back into the space between the steel strips and their mounting surfaces, thus avoiding corrosion at the bottom of the steel strips.

[0017] Preferably, the supporting body is equipped with a liquid-guiding and storage structure that allows for timely drainage of oil and water from the collection tank.

[0018] Preferably, the liquid-guiding and accumulating structure includes an oil receiving pan welded to the supporting body and located below the liquid collecting tank, and an oil guiding tank welded to the supporting body for receiving oil and water dripping from the liquid collecting tank and guiding it into the oil receiving pan.

[0019] The capacity of the collection tank is limited by the above scheme. Therefore, a liquid guiding and storage structure is set up to quickly guide the oil and water in the collection tank to the oil receiving pan.

[0020] Preferably, an oil drain pipe, oil drain valve, or oil drain plug is provided at the bottom of the oil receiving pan.

[0021] Using the above solutions, all the aforementioned components can drain the oil and water from the oil receiving pan.

[0022] Preferably, end plates are welded to both ends of the support body, and lifting lugs are welded to the outer wall of the end plates.

[0023] The above design facilitates the movement of the support beam or the entire machine body.

[0024] This utility model, by adopting the above technical solutions, has significant technical effects: the original support beam with its upper and lower bottom plates and upright plates being welded and fixed is replaced by an integrally formed structure, saving a lot of welding work and reducing production difficulty; the support body, being integrally formed, has significantly improved strength, and even with a detachable and fixed connection to the connecting beam, it can still provide support during the movement of the moving template. Therefore, replacing the original welding connection between the support beam and the connecting beam with a detachable and fixed connection allows the modular mold-closing machine body to be transported and stored in a modular form and assembled during use, which not only reduces production difficulty but also improves the convenience of transportation and storage.

Detailed Implementation

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0033] A split-type mold-closing machine body, as shown in the reference Figures 2-6 As shown, it includes a head plate support plate 3 for supporting the fixed template, a support beam for supporting the moving template, and a connecting beam 11 that forms a rectangular frame structure after being connected with the support beam.

[0034] Two support beams are arranged in parallel. Each support beam includes a support body 1 with an integral structure and an auxiliary support plate 4 welded to one side of the support body 1. In this embodiment, the support body 1 is made of I-beam. Several auxiliary support plates 4 are distributed at intervals along the length of the support body 1. The side of the auxiliary support plate 4 close to the support body 1 is welded and fixed to the upper and lower ends of the support body 1. The auxiliary support plate 4 is located on the opposite side of the two parallel support bodies 1.

[0035] Two head plate support plates 3 are arranged in parallel and each is connected to one end of the two supporting bodies 1 on opposite sides. In order to eliminate the gap between the sliding foot of the moving template and the head plate support plate 3, a connecting plate 2 is welded between the head plate support plate 3 and the supporting body 1. Two connecting plates 2 are welded on the top and bottom of each head plate support plate 3. These two connecting plates 2 are welded and fixed to the top and bottom surfaces of the supporting body 1 respectively. In practical applications, the connecting plate 2 of appropriate thickness can be selected according to the size of the sliding foot of the moving template.

[0036] Three connecting beams 11 are arranged in parallel at intervals. Two of the connecting beams 11 are connected between the two head plate support plates 3, and the other connecting beam 11 is connected between the ends of the two support bodies 1 away from where the head plate support plate 3 is installed.

[0037] The connecting beam 11 is fixedly connected to the support beam and the head plate support plate 3 through a detachable structure. The detachable structure includes a connecting block 10 welded and fixed to the support body 1 or the head plate support plate 3 and having a mounting hole 1001. The connecting beam 11 is provided with an assembly hole 1101 corresponding to the mounting hole 1001. After the bolt passes through the mounting hole 1001 and the assembly hole 1101 in sequence, it is locked with a nut to fix the connecting beam 11 and the connecting block 10, thus realizing the fixed connection between the connecting beam 11 and the support beam.

[0038] A steel strip mounting surface 101 is provided on the upper end face of the support body 1. A liquid collection tank 102, which is lower than the steel strip mounting surface 101 and used to collect oil and water, is milled on the outer periphery of the upper end face of the support body 1. A liquid guiding and storage structure is provided on the support body 1 to timely discharge the oil and water in the liquid collection tank 102. The liquid guiding and storage structure includes an oil receiving pan 6 welded to the support body 1 and located below the liquid collection tank 102, and an oil guiding groove 5 welded to the support body 1 to collect the oil and water dripping from the liquid collection tank 102 and guide it into the oil receiving pan 6. An oil drain pipe 7 is provided at the bottom of the oil receiving pan 6, and the other end of the oil drain pipe 7 is directly connected to the waste liquid collection device.

[0039] End plates 8 are welded to both ends of the supporting body 1, and lifting lugs 9 are welded to the outer wall of the end plates 8.

[0040] The original support beams, which required welding of the upper and lower base plates and vertical plates, were directly replaced with one-piece molded I-beams, eliminating the welding process of the original three plates and reducing production difficulty. The support body 1 made of this I-beam is significantly stronger due to its one-piece molding. Combined with the setting of the auxiliary support plate 4, even if it is detachably fixedly connected to the connecting beam 11, it can still meet the support requirements during the movement of the moving template. Therefore, the original method of welding the support beams and connecting beams 11 was replaced with a detachable fixed connection. This split-type mold-closing machine body is transported and stored in a split form and assembled when in use, which not only reduces production difficulty but also improves the convenience of transportation and storage.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
