Description

Technical Field

[0001] The utility model relates to the field of preheating devices, in particular to a casting mould preheating device. Background Art

[0002] Molds are tools used to manufacture a variety of industrial products, enabling mass production of products of identical shape and size. Molds play a vital role in the manufacturing industry and are widely used in industries such as plastics processing, metal forming, rubber manufacturing, and glass manufacturing. Molds allow for the rapid production of parts, improving production efficiency.

[0003] The purpose of mold preheating is to prevent mold cracking caused by thermal shock and reduce the increased mold force caused by the sudden chilling of the casting due to mold temperature, which can lead to damage to the ejector and core. When preheating multiple molds of the same size, they are first placed in a preheating furnace. The preheating furnace uses upper and lower heating tubes to bake the molds, which can quickly increase the mold temperature within the preheating furnace, ensuring quality and efficiency during the product molding process. At the same time, the energy-saving characteristics of the mold preheating furnace also reduce production costs and improve economic benefits for enterprises.

[0004] However, when the mold is pushed into the preheating furnace, there is no restriction between the parts, which will cause squeezing between the molds, resulting in uneven heating of the mold when it is heated quickly. As the number of uses increases, long-term uneven heating will affect the service life of the mold, and thus affect the practicality of the mold. Utility Model Content

[0005] Based on this, the purpose of the present invention is to provide a casting mold preheating device to solve the technical problems mentioned in the above background technology.

[0007] By adopting the above technical solution, when the user places the mold on the support plate, the molds will not fit together due to the limitation of the fixed block. At the same time, through the cooperation of the screw rod and the handle, the space can be flexibly and evenly divided to ensure that the preheating furnace can adapt to molds of different sizes, effectively avoiding the situation where the preheating furnace can only adapt to molds of one size, and further enhancing the practicality of the preheating furnace.

[0008] Furthermore, the transmission assembly includes a rotating wheel, a first sliding groove, a second sliding groove and a handle, and the outer wall of the rotating wheel is fixedly connected to the end of the screw rod, and the rotating wheel is slidably connected to the handle.

[0009] By adopting the above technical solution, it is ensured that the support plate can better enter the preheating furnace.

[0010] Furthermore, the rotating wheel is rotatably connected in the support plate, and a second sliding groove corresponding to the handle is opened in the rotating wheel, and a first sliding groove corresponding to the handle is opened on the outer wall of the support plate.

[0011] By adopting the above technical solution, it is ensured that the handle drives the rotating wheel smoothly.

[0012] Furthermore, a plurality of the first fixing blocks are installed at equal intervals on the outer wall of the support plate, and a sliding groove corresponding to the connecting plate is opened in the support plate.

[0013] By adopting the above technical solution, it is ensured that the mold will not move on the support plate, and it is ensured that the connecting plate can slide smoothly inside the support plate.

[0014] Furthermore, a plurality of connecting plates are installed at equal intervals on the outer wall of the screw rod, and the screw rod and the connecting plates are threadedly connected.

[0015] By adopting the above technical solution, it is ensured that the connecting plate can be smoothly moved by the screw rod.

[0016] Furthermore, the cross section of the second fixing block is U-shaped, and multiple groups of second fixing blocks are installed at equal intervals on the outer wall of the connecting plate, and the outer wall of the support plate is provided with sliding grooves corresponding to the second fixing blocks.

[0017] By adopting the above technical solution, it is ensured that the second fixing block slides smoothly on the outer wall of the support plate under the drive of the connecting plate.

[0018] Furthermore, the support plate wall is fixedly connected to the end of the telescopic rod, and the connecting plate is slidably connected to the telescopic rod.

[0019] By adopting the above technical solution, it is ensured that the connecting plate slides smoothly on the outer wall of the telescopic rod.

[0020] In summary, the present invention has the following beneficial effects:

[0021] The utility model is provided with a fixing block, a screw rod, a telescopic rod, a connecting plate and a handle, so that when the user places the mold on the support plate, the molds will not fit together under the restriction of the fixing block. At the same time, through the cooperation of the screw rod, the rotating wheel and the handle, the space can be flexibly and evenly divided, ensuring that the preheating furnace can adapt to molds of different sizes, effectively avoiding the situation where the preheating furnace can only adapt to molds of one size, and further enhancing the practicality of the preheating furnace.

The screw rod 4 starts to rotate, so that the connecting plate 5 starts to move on the outer wall of the screw rod 4, and at the same time drives the second fixed block 6 to start sliding. The movement of the second fixed block 6 causes the movement of the support plate 2, so that the space of the support plate 2 is divided by the second fixed block 6, ensuring that the preheating furnace 1 can adapt to molds of different sizes, a driving component for driving the screw rod 4 is installed in the support plate 2, a telescopic rod 11 is fixedly installed on the inner wall of the preheating furnace 1, the support plate 2 pulls the telescopic rod 11, and the telescopic rod 11 starts to retract and retract, so that the support plate 2 can be better supported in the preheating furnace 1, ensuring the stability of the support plate 2.

[0031] See also Figure 2 and Figure 3The driving assembly includes a rotating wheel 7, a first slide groove 8, a second slide groove 9 and a handle 10, and the outer wall of the rotating wheel 7 is fixedly connected to the end of the screw rod 4, and the rotating wheel 7 is slidably connected to the handle 10. The handle 10 is inserted into the rotating wheel 7, and the handle 10 is rotated to drive the rotating wheel 7 to rotate, so that the handle 10 can be separated from the rotating wheel 7, ensuring that the support plate 2 can better enter the preheating furnace 1.

[0032] See also Figure 1 and Figure 3 The rotating wheel 7 is rotatably connected in the support plate 2, and a second sliding groove 9 corresponding to the handle 10 is opened in the rotating wheel 7. The handle 10 slides into the rotating wheel 7 through the second sliding groove 9, and a first sliding groove 8 corresponding to the handle 10 is opened on the outer wall of the support plate 2. The handle 10 drives the rotating wheel 7 to rotate, and the handle 10 slides in the first sliding groove 8, so that the handle 10 slides smoothly in the first sliding groove 8 when it rotates, ensuring that the handle 10 drives the rotating wheel 7 smoothly.

[0033] See also Figure 2 - Figure 4 A plurality of first fixing blocks 3 are installed at equal intervals on the outer wall of the support plate 2. The equal interval distribution of the first fixing blocks 3 allows the mold to be restricted by the first fixing blocks 3 when placed on the support plate 2, ensuring that the mold will not move on the support plate 2. A sliding groove corresponding to the connecting plate 5 is opened in the support plate 2, and the connecting plate 5 slides on the support plate 2, so that the connecting plate 5 slides smoothly on the support plate 2, ensuring that the connecting plate 5 can slide smoothly in the support plate 2.

According to the size of the mold to be placed, the user first inserts the handle 10 into the rotating wheel 7 through the second slide groove 9 and turns the handle 10. The handle 10 starts to slide in the first slide groove 8. The handle 10 drives the rotating wheel 7 to rotate, and the rotating wheel 7 drives the screw rod 4 to start rotating, so that the connecting plate 5 starts to move on the outer wall of the screw rod 4, and at the same time drives the second fixed block 6 to start sliding until the second fixed block 6 slides to a suitable position. The user puts in the mold. Under the restriction of the second fixed block 6 and the first fixed block 3, the mold remains relatively stationary on the support plate 2. The user pulls out the handle 10. At this time, by pushing the support plate 2 to move into the preheating furnace 1, the user can start using the preheating furnace 1 to preheat the mold.
