Description

Technical Field

[0001] The utility model relates to the technical field of forming molds, in particular to a forming mold which is convenient for taking materials. Background Art

[0002] The use of degradable packaging materials is becoming more and more widespread, among which the demand for paper-plastic packaging products has increased dramatically. When producing paper-plastic products, the product mold corresponding to the production plan is usually loaded into the paper-plastic molding machine, and then the required products are produced through molding, hot pressing and other processes. During use, the lower mold insert is fixed on the mold ejector, and the mold ejector is fixed on the upper mold plate. The upper mold plate is pressed down, and the mold ejector moves with the upper mold plate, and the lower mold insert is pushed into the cavity to complete the mold closing process, so that a molding cavity is formed between the lower mold insert and the lower mold plate, and then the product is molded.

[0003] However, after the above-mentioned molding mold is opened, the product will be temporarily attached to the lower mold insert. When the next mold is closed, the product needs to be removed from the lower mold insert before the next mold closing operation can be performed. Therefore, fixing the lower mold insert on the mold ejector pin will also reduce production efficiency. Utility Model Content

The slider 22 is pressed and slid by the slider blocks 23 on both sides. When the mold is closed, the shovel 12 on the lower template 1 penetrates the concave template 2 upward and is inserted into the slider 22. When the shovel 12 rises, it pushes the slider 22 to press the slider block 23. Sliding smoothly, the slider 22 is pushed to extrude the sheet material and press it on the punch part 4 during mold closing. When the mold is opened, the upper mold plate 3 is started to move upward, and the formed sheet material is tensioned and extruded on the punch part 4. Then the cylinder 41 on the upper mold plate 3 is started to push the lifting punch 43 in the punch part 4 to move vertically upward. The punch part 4 lacks the support of the lifting punch 43, causing the sliding punch 45 to slide horizontally under the deformation pressure of the return spring 46, so that the two sides of the punch part 4 are no longer tensioned to extrude the formed sheet material, and the formed sheet material falls downward.
