DETAILED DESCRIPTION

[0021] See also Figures 1 - 5 , an automobile engineering mold fixing device, comprising a fixing mechanism 1 and an adjusting mechanism 2;

[0022] The fixing mechanism 1 makes it easier to fix the movable mold 105 and the fixed mold 106 and can automatically eject the molded part from the fixed mold 106. The adjusting mechanism 2 is used to drive the internal structure of the fixing mechanism 1 to move.

[0023] The fixing mechanism 1 includes a mounting frame 101, a center plate 102 is fixed on the surface of the mounting frame 101, a cylinder 103 is fixed on the top of the mounting frame 101, one end of the cylinder 103 passes through the mounting frame 101 and is fixed with a linkage plate 104, a movable mold 105 is fixed at the bottom of the linkage plate 104, a pouring port is provided on the top of the movable mold 105, a fixed mold 106 is fixed on the top of the center plate 102, two connecting plates 107 are fixed on both sides of the surface of the movable mold 105, the connecting plate 107 slides through the center plate 102 and is fixed with a combination plate 108, an ejector plate 109 is fixed on the top of the combination plate 108, the ejector plate 109 passes through the center plate 102 and the fixed mold 106, L-shaped plates 110 are provided on the left and right sides of the linkage plate 104, a spring 111 is fixed on the surface of the L-shaped plate 110, a limit block 112 is fixed at the bottom of the spring 111, and the limit block 112 is wedge-shaped.

[0024] When the moving die 105 and the fixed die 106 are closed, the starting cylinder 103 drives the linkage plate 104 to move downward, so that the moving die 105 can fit onto the top of the fixed die 106. At the same time, the linkage plate 104 drives the connecting plate 107 to move downward, so that the combined plate 108 drives the ejector plate 109 to move downward together, making the shape of the top of the ejector plate 109 adaptable to the shape of the inner wall of the fixed die 106. Then, the adjusting mechanism 2 moves the two L-shaped plates 110 towards each other. During the movement of the two L-shaped plates 110, the inclined surface on the surface of the limit block 112 contacts the inclined surface on the top of the linkage plate 104, enabling the limit block 112 to move upward by itself, so that the spring 111 can be compressed, and the limit block 112 can apply pressure to the top of the linkage plate 104, making the moving die 105 closely fit on the top of the fixed die 106, thereby improving the fixing effect between the moving die 105 and the fixed die 106. At this time, pouring and molding can be carried out through the pouring port on the top of the moving die 105. After pouring is completed, first, the adjusting mechanism 2 moves the two L-shaped plates 110 in the reverse direction, and then the cylinder 103 moves the linkage plate 104 upward, so that the linkage plate 104 drives the ejector plate 109 to move upward through the connecting plate 107 and the combined plate 108. In this way, when the moving die 105 and the fixed die 106 are separated, the ejector plate 109 can eject the molded part inside the fixed die 106 together, so that the operator does not need to manually take out the molded part located inside the fixed die 106, thereby improving the convenience of using the device and increasing the production efficiency.

[0025] Further, the adjusting mechanism 2 includes an installation shell 201. The installation shell 201 is fixed on the surface of the central plate 102. A bidirectional lead screw 202 is rotatably connected to the inner wall of the installation shell 201. A motor 203 is fixed on the surface of the installation shell 201. The output shaft of the motor 203 penetrates the installation shell 201 and is fixedly connected to one end of the bidirectional lead screw 202. Two first sliding sleeves 204 are threadedly connected to the surface of the bidirectional lead screw 202. A plurality of sliding grooves 205 are formed on the surface of the installation shell 201. The L-shaped plate 110 is slidably connected to the surface of the sliding groove 205. The top of the first sliding sleeve 204 is fixedly connected to the bottom of the L-shaped plate 110;

[0026] When the motor 203 starts, it drives the bidirectional lead screw 202 to rotate, enabling the first sliding sleeve 204 to move towards each other or in the opposite direction under the influence of the thread, so that the first sliding sleeve 204 can drive the L-shaped plate 110 to move synchronously.

[0027] Further, a sealing frame 115 is fixed to the bottom of the moving die 105. A slot for cooperating with the sealing frame 115 is provided on the surface of the fixed die 106. A sealing gasket 116 is fixed to the inner wall of the fixed die 106;

[0028] After the moving die 105 is fitted to the top of the fixed die 106, the sealing frame 115 will enter the interior of the slot. At the same time, the sealing gasket 116 will closely fit the surface of the sealing frame 115, thereby improving the sealing performance between the moving die 105 and the fixed die 106.

[0029] Furthermore, a baffle 114 is fixed on the surface of the L-shaped plate 110, and the top of the baffle 114 is slidably connected to the bottom of the limit block 112;

[0030] The baffle 114 can limit the lowest position of the limit block 112 to prevent the limit block 112 from moving to a position where the surface inclined plane cannot contact the upper surface of the linkage plate 104.

[0031] Furthermore, a telescopic rod 113 is fixed to the top of the limit block 112, and the top of the telescopic rod 113 is fixedly connected to the surface of the L-shaped plate 110;

[0032] The telescopic rod 113 can guide the limit block 112, enabling the limit block 112 to only move up and down and preventing the limit block 112 from tilting and rotating.

[0033] Furthermore, two guide rods 206 are fixed to the inner wall of the mounting shell 201. A second sliding sleeve 207 is slidably connected to the surface of the guide rod 206, and the top of the second sliding sleeve 207 is fixedly connected to the bottom of the L-shaped plate 110;

[0034] When the L-shaped plate 110 moves, it will drive the second sliding sleeve 207 to slide on the surface of the guide rod 206, thereby enabling the L-shaped plate 110 to obtain a guiding effect and improving the stability of the L-shaped plate 110 during movement.

[0035] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
