[0026] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation methods of the present invention are now described with reference to the accompanying drawings, but the protection scope of the present invention is not limited to the following.
[0027] Reference Figures 1-5 As shown, a mold assembly for a front wall panel of an automobile includes a lower mold 1 and an upper mold 2. Two inverted T-grooves 3 are symmetrically opened on the upper mold 2. Insert blocks 4 are provided on the inner sides of the two inverted T-grooves 3. Two transmission mechanisms 5 are provided on the upper mold 2, and the two transmission mechanisms 5 are respectively located on the inner sides of the two inverted T-grooves 3. The bottom of the transmission mechanism 5 is fixedly connected to the insert blocks 4. Four buffer assemblies 6 are provided on the lower mold 1, and the four buffer assemblies 6 are arranged in a square shape. Four limit assemblies 7 are provided on the lower mold 1, and the four limit assemblies 7 are respectively located on the inner sides of the four buffer assemblies 6.
[0028] The present invention provides a technical solution. When in use, the transmission mechanism 5 is pressed down, so that the insert block 4 on the inner side of the inverted T-groove 3 can push the front wall plate out for blanking. At the same time, under the action of the insert block 4, the contact area between the transmission mechanism 5 and the front wall plate can be increased, thereby preventing scratches due to the small contact area. Then, through the limit component 7, the stability of the upper mold 2 during lifting and lowering can be guaranteed, so that the upper mold 2 and the lower mold 1 are always parallel to each other. Finally, under the action of the buffer component 6, the downward pressure of the upper mold 2 can be buffered to avoid damage to the lower mold 1 due to excessive downward pressure on the upper mold 2.
[0029] Preferably, the buffering assembly 6 comprises a cylindrical groove 61 formed on the lower mold 1, the inside of the cylindrical groove 61 is provided with a first spring 62, and the bottom of the first spring 62 is fixedly connected with the lower mold 1, and the bottom of the upper mold 2 is fixedly installed with a hollow cylinder 63, and the hollow cylinder 63 is opposite to the cylindrical groove 61.
[0030] Specifically, when the upper mold 2 is pressed down, the hollow cylinder 63 is inserted into the cylindrical groove 61 and extrudes the first spring 62, and then the first spring 62 can buffer the pressing force of the upper mold 2, avoiding the damage of the lower mold 1 caused by the excessive pressing force of the upper mold 2.
[0031] Preferably, the limiting assembly 7 comprises a plug-in rod 71 arranged in the cylindrical groove 61, and the bottom of the plug-in rod 71 is fixedly connected with the lower mold 1, and the first spring 62 is located outside the plug-in rod 71, and the bottom of the upper mold 2 is provided with a plug-in groove, and the diameter of the plug-in groove is equal to the diameter of the inner cavity of the hollow cylinder 63, and the top end of the plug-in rod 71 is inserted between the hollow cylinder 63 and the plug-in groove.
[0032] Specifically, through the plug-in rod 71 and the plug-in groove, the stability and smoothness of the upper mold 2 during lifting can be ensured, so that the upper mold 2 and the lower mold 1 are always parallel and can be quickly aligned.
[0033] Preferably, the transmission mechanism 5 comprises a T-shaped rod 51 movably inserted into the inverted T-shaped groove 3, and the bottom of the T-shaped rod 51 is fixedly connected with the plug 4, and the outer wall of the T-shaped rod 51 is provided with a second spring 52, and the second spring 52 is located between the upper mold 2 and the disc end of the T-shaped rod 51.
[0034] Specifically, the T-shaped rod 51 is pressed by the cylinder and other driving mechanisms on the machine, so that the plug 4 in the inverted T-shaped groove 3 can push the front wall plate out of the blank, and then when the cylinder and other driving mechanisms reset, the second spring 52 which is deformed under pressure pushes the T-shaped rod 51, so that the T-shaped rod 51 can drive the plug 4 to reset.
[0035] Preferably, the upper mold 2 is provided with a connecting frame 8, and the two T-shaped rods 51 are fixedly installed on the connecting frame 8, and the shape of the T-shaped rod 51 is U-shaped.
[0036] Specifically, through the connecting frame 8, the two T-shaped rods 51 only need to be pressed by one cylinder and other driving mechanisms, and in addition, since the connecting frame 8 is U-shaped, the connecting frame 8 has good bending deformation resistance, thereby ensuring its stability and safety.
[0037] The above only discloses preferred embodiments of the present application, and of course cannot limit the scope of the present application, therefore equivalent changes made according to the present application claims still belong to the scope of the present application.
