[0001] This utility model relates to the field of automotive mold technology that is easy to replace and fix, specifically an automotive mold that is easy to replace and fix. Background Technology

[0002] Automotive molds are specialized process equipment used in automobile manufacturing to mold various parts, and are one of the core foundations of the automotive industry.

[0003] For example, a car mold with the authorization announcement number "CN211191712U" is easy to replace and fix. A punch is provided on one side of the movable rod at the lower end of the upper connecting plate, and a movable groove is hollowed out on the outer surface of one end of the lower fixing block. A storage mechanism is connected inside the movable groove. This easy-to-replace and fix car mold facilitates mold installation and waste material handling and storage, making mold placement and installation more stable. However, in the use of the car mold, the fixing mechanism relies on four independent connecting screws, rotating discs, and limiting plates to fix the lower fixing block. During installation, the four rotating discs need to be rotated separately to adjust the position of the limiting plate. This decentralized adjustment method results in many operation steps for the car mold, making it prone to inconsistent adjustment of the limiting plate. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the decentralized adjustment method leads to many operation steps in the automotive mold, which makes the limiting plate adjustment of the automotive mold prone to inconsistency. Therefore, this invention proposes an automotive mold that is easy to replace and fix.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design an easy-to-replace and fixed automobile mold, including a bracket and columns. The top four corners of the bracket are fixedly connected to the bottom of multiple columns. The front and rear sides of the bracket are respectively connected to fixing structures. The top of the columns is fixedly connected to a top plate. The outer wall of the top plate is connected to a control structure.

[0007] Preferably, the fixing structure includes a housing and a straight rod. The inner sides of the two housings are respectively fixed to the front and rear sides of the bracket. The outer circular opening of the housing is slidably connected to the outer wall of the straight rod. A ring is fixed to the outer wall of the straight rod. A curved plate is fixed to the outer wall of the ring. A protruding rod is fixed to the outer wall of the curved plate. A spring is sleeved on the outer wall of the straight rod. The two ends of the spring are respectively fixed to the inner wall of the housing and the outer wall of the ring.

[0008] Preferably, the inner side of the outer wall of the straight rod penetrates the outer wall of the bracket.

[0009] Preferably, the upper part of the outer wall of the protruding rod is slidably connected to the top groove of the outer casing.

[0010] Preferably, an automobile mold is inserted into the inner wall of the bracket, and the outer circular opening of the automobile mold is inserted into the inner side of the outer wall of the straight rod.

[0011] Preferably, the control structure includes an electric telescopic rod and a horizontal plate. The outer wall of the electric telescopic rod is fixedly connected to the outer wall of the top plate, the output end of the electric telescopic rod is fixedly connected to the top of the horizontal plate, and a material cylinder is fixedly connected to the outer wall of the horizontal plate.

[0012] Preferably, the outer wall of the material cylinder is clearance-fitted with the outer wall of the top plate.

[0013] This utility model proposes a convenient and replaceable fixed automobile mold. The advantages are as follows: By holding the outer wall of the protruding rod in the fixing structure and pulling it outwards, the protruding rod, under force, moves the curved plate forward. The moving curved plate moves the ring forward, and then the ring, under force, moves the straight rod forward, causing the inner side of the straight rod's outer wall to retract into the bracket. At this point, the outer wall of the straight rod disengages from the outer opening of the automobile mold. Then, the automobile mold is pulled to the right to disengage from the bracket. Subsequently, a new automobile mold is inserted into the bracket, and then the protruding rod is released. The spring, having lost its tension, provides a rebound force, causing the ring to move the straight rod inwards, allowing the inner side of the straight rod's outer wall to engage with the outer opening of the automobile mold, thus completing the installation of the new automobile mold. This changes the original decentralized adjustment and fixing method, reduces the number of automobile mold operation steps, and prevents inconsistent adjustment of the limit plate in automobile molds.

[0021] The present invention will be further described below with reference to the accompanying drawings:

[0022] Please see Figure 1-6 In this embodiment, a car mold that is easy to replace and fix includes a bracket 1 and a column 4. The top four corners of the bracket 1 are fixedly connected to the bottom of a plurality of columns 4 respectively. The front and rear sides of the bracket 1 are respectively connected to a fixing structure 2. The top of the column 4 is fixedly connected to a top plate 5. The column 4 supports the top plate 5. The outer wall of the top plate 5 is connected to a control structure 3.

[0023] The fixed structure 2 includes a housing 201 and a straight rod 202. The inner sides of the two housings 201 are fixedly connected to the front and rear sides of the bracket 1, respectively. The outer wall of the housing 201 is slidably connected to the outer wall of the straight rod 202. The straight rod 202 slides back and forth through the outer wall of the housing 201 under force. A ring 203 is fixedly connected to the outer wall of the straight rod 202. A curved plate 204 is fixedly connected to the outer wall of the ring 203. A protruding rod 205 is fixedly connected to the outer wall of the curved plate 204. A spring 206 is sleeved on the outer wall of the straight rod 202. The two ends of the spring 206 are fixedly connected to the inner wall of the housing 201 and the outer wall of the ring 203, respectively. After the ring 203 moves outward under force, it rebounds due to the elastic force of the spring 206. The inner side of the outer wall of the straight rod 202 penetrates the outer wall of the bracket 1. The upper part of the outer wall of the protruding rod 205 is slidably connected to the top slot of the housing 201. The protruding rod 205 slides back and forth through the top slot of the housing 201 under force.

[0024] By holding the outer wall of the protruding rod 205 in the fixed structure 2 and pulling it outward, the protruding rod 205 moves the curved plate 204 forward under force. The moving curved plate 204 moves the ring 203 forward, and then the ring 203 moves the straight rod 202 forward under force, causing the inner side of the outer wall of the straight rod 202 to retract into the bracket 1. At this time, the outer wall of the straight rod 202 disengages from the outer wall of the car mold 6. Then, the car mold 6 is pulled to the right to disengage from the bracket 1. Subsequently, the new car mold 6 is inserted into the bracket 1. Then, the protruding rod 205 is released, and the spring 206 loses its tension and provides a rebound force, causing the ring 203 to move the straight rod 202 inward, so that the inner side of the outer wall of the straight rod 202 is inserted into the outer wall of the car mold 6, completing the installation of the new car mold. This changes the original decentralized adjustment and fixing method, reduces the operation steps of the car mold, and prevents the car mold from having inconsistent adjustment of the limit plate.

[0025] The inner wall of the bracket 1 is fitted with an automobile mold 6. The outer circular opening of the automobile mold 6 is fitted with the inner side of the outer wall of the straight rod 202. The control structure 3 includes an electric telescopic rod 301 and a horizontal plate 302. The outer wall of the electric telescopic rod 301 is fixedly connected to the outer circular opening of the top plate 5. The electric telescopic rod 301 is a multi-stage electric telescopic rod with a self-locking function at the output end. The output end of the electric telescopic rod 301 is fixedly connected to the top of the horizontal plate 302. The outer circular opening of the horizontal plate 302 is fixedly connected with a material cylinder 303. The outer wall of the material cylinder 303 is clearance-fitted with the outer circular opening of the top plate 5. The material cylinder 303 moves up and down through the outer circular opening of the top plate 5 under force.

[0026] Working principle:

[0027] Car mold fixing:

[0028] Grasp the outer wall of the protruding rod 205 and pull it outward. The protruding rod 205, under force, moves the curved plate 204 forward. The moving curved plate 204 moves the ring 203 forward. Then, the ring 203, under force, moves the straight rod 202 forward, causing the inner side of the outer wall of the straight rod 202 to retract into the bracket 1. At the same time, the ring 203 stretches the spring 206. Then, insert the car mold 6 into the bracket 1. Next, release the protruding rod 205. The spring 206 loses its tension and provides a rebound force, causing the ring 203 to move the straight rod 202 inward, so that the inner side of the outer wall of the straight rod 202 is inserted into the outer wall of the car mold 6, completing the installation of the car mold.

[0029] Automotive mold injection molding work:

[0030] When the electric telescopic rod 301 is powered on, its output end moves the horizontal plate 302 downwards. The moving horizontal plate 302 moves the material cylinder 303 downwards, causing the bottom of the outer wall of the material cylinder 303 to engage with the injection port at the top of the car mold 6. Material is then poured into the material cylinder 303 and subsequently enters the car mold 6. Afterwards, the output end of the electric telescopic rod 301 moves the horizontal plate 302 upwards, causing the horizontal plate 302 to move the material cylinder 303 upwards, thus detaching the material cylinder 303 from the car mold 6.

[0031] Then, grasp the outer wall of the protruding rod 205 and pull it outward. The protruding rod 205, under force, moves the curved plate 204 forward. The moving curved plate 204 moves the ring 203 forward. Then, the ring 203, under force, moves the straight rod 202 forward, causing the inner side of the outer wall of the straight rod 202 to retract into the bracket 1. At this time, the outer wall of the straight rod 202 disengages from the outer wall opening of the car mold 6. Then, pull the car mold 6 to the right to disengage from the bracket 1. Then, insert the new car mold 6 into the bracket 1 and release the protruding rod 205. The spring 206 loses its tension and provides a rebound force, causing the ring 203 to move the straight rod 202 inward, so that the inner side of the outer wall of the straight rod 202 is inserted into the outer wall opening of the car mold 6, completing the installation of the new car mold. Then, injection molding is performed on the fixed car mold 6. After the removed car mold 6 cools down, the upper mold is pulled upward to disengage from the lower mold. Then, the car part model is removed from the car mold 6.

[0032] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
