Because the right end surface has a platform structure and the stroke of the second side-pulling mechanism is long, an extension plate 76 for increasing the core-pulling stroke is arranged at one end of the right forming block 71 on the fixed die plate 2.

A second mold opening travel switch 77 is arranged at one end, located on one side of the right forming block 71 and far away from the right forming block 71, of the fixed mold plate 2, a second mold closing travel switch 78 is arranged at one end, located on one side of the right forming block 71 and close to the right forming block 71, of the fixed mold plate 2, and a second contact block 79 acting on the first mold closing travel switch 67 is arranged on the first driving block 62. When the mold is opened, the second driving cylinder 73 stops moving after the right forming block 71 contacts the second mold opening travel switch 77; when the mold is closed, the second contact block 79 stops moving after contacting the second mold closing stroke switch 78 and the second driving cylinder 73; thereby ensuring the accuracy of the movement position of the second side-pulling mechanism.

Referring to fig. 5 and 9, the third side drawing mechanism includes a side forming block 81 for forming a side surface structure of a product, an inclined guide post 82 fixed to the movable platen 1, and a side slider 83 slidably coupled to the fixed platen 2. The side forming block 81 is fixed to a side slider 83, and the side slider 83 is provided with an inclined slide groove 84 through which the inclined guide post 82 passes. Here, because the side surface of the product is a large surface, the surface area of the side forming block 81 is large, so that the production and processing are convenient, and simultaneously, because the side insert 85 has a plurality of edge structures, the insert is separately processed in a split insert mode, so that the generation of waste products can be reduced. Namely, the side forming block 81 is provided with a side insert 85 for forming a side surface rib structure, and the side insert 85 is fixed to the side forming block 81 by a screw.

Wherein, the side of the side forming block 81 departing from the fixed mold core 5 is an inclined surface with the upper end inclined towards one side of the fixed mold core 5, the movable mold plate 1 is provided with a side pressing block 86 for pressing the side of the side forming block 81 during mold closing, and the side pressing block 86 and the side forming block 81 are both inclined surfaces. Thus, the position of the side forming block 81 can be more accurate by the side pressing block 86 during die assembly; and during mold opening, the side forming block 81 is abducted by means of the inclined plane, so that smooth demolding of the product is guaranteed.

In addition, in order to facilitate the positioning of the side forming block 81 during processing and to facilitate the processing, a positioning column 87 is fixed at one end of the inclined surface of the side forming block 81, which is far away from the fixed die plate 2, so as to facilitate the clamping and positioning of the side forming block 81.

The demolding process of the inverted demolding structure of the injection mold of the automobile auxiliary instrument panel is explained in detail as follows:

after the product is injection molded, firstly, the movable mold and the fixed mold are separated. Here, since the angle guide 82 and the side press block 86 are fixed to the moving platen 1, the side press block 86 gradually separates from the surface of the side forming block 81 as the moving platen 1 moves away from the fixed platen 2; meanwhile, the side sliding block 83 drives the side forming block 81 to be far away from the surface of the product under the action of the inclined guide post 82; in the process, the interference of the movement of the side forming block 81 and the side pressing block 86 is avoided due to the matching of the inclined surfaces of the two blocks.

Then, the first side-pulling mechanism and the second side-pulling mechanism move synchronously, and the left forming block 61 and the right forming block 71 are separated from the two ends of the product.

Finally, the first driving oil cylinder 11 drives the top plate 10 to move upwards, and the product is ejected out of the surface of the core insert 5 under the action of the ejector pin group 9, so that the product is smoothly demoulded. In the process, because the product mounting surface has a plurality of large surfaces, the thimble groups 9 jointly act on the contour part and the large surface part of the mounting surface, so that the product is more smoothly demoulded.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
