Description

Demoulding structure convenient for plastic suction mould Technical Field The utility model relates to the technical field of plastic suction molds, in particular to a demolding structure convenient for a plastic suction mold. Background The plastic suction is a plastic processing technology, and the main principle is that after the flat plastic hard sheet is heated and softened, vacuum adsorption is adopted on the surface of a die, and the plastic is cooled and molded, so that the plastic suction is widely used in the industries of plastic packaging, lamp decoration, advertisement, decoration and the like; However, for some plastic uptake products with buckle structures, the plastic uptake mold is provided with a back-off groove for forming the buckle, and the buckle after plastic uptake forming is positioned in the back-off groove, so that great difficulty is brought to the demoulding of the plastic uptake products. Disclosure of utility model The utility model aims to provide a demoulding structure which is convenient for a plastic sucking mould and has the advantage of being convenient for demoulding of plastic sucking products with buckle structures. To achieve the above and other related objects, the present utility model provides the following technical solutions: a demoulding structure convenient for a plastic suction mould comprises a mould seat and a forming mould fixedly arranged on the mould seat; The side wall of the forming die is obliquely and slidably provided with a sliding block, the back-off groove is formed in the sliding block, and when the sliding block slides from bottom to top, the sliding block gradually approaches inwards so that the buckle breaks away from the back-off groove. In an embodiment of the utility model, a sliding groove is provided on the forming mold, and the sliding block is slidingly connected in the sliding groove. In an embodiment of the utility model, the side wall of the chute is provided with a first inclined surface inclined inwards; the side wall of the sliding block is provided with a second inclined plane attached to the first inclined plane. In an embodiment of the utility model, an elastic member with one end connected with the sliding block is fixedly arranged at the bottom of the sliding groove. In an embodiment of the utility model, the elastic member is a tension spring; The lower guide post is fixedly arranged at the bottom of the sliding groove, the upper guide post is fixedly arranged at the bottom of the sliding block, and two ends of the tension spring are respectively sleeved on the lower guide post and the upper guide post. In an embodiment of the utility model, a plurality of molding dies are fixedly disposed on the die base. As described above, the demoulding structure for the plastic suction mould has the following beneficial effects: The slide block is obliquely arranged on the side wall of the forming die, the back-off groove is arranged on the slide block, the power for demolding after the product is subjected to plastic suction forming drives the slide block to slide obliquely upwards, the slide block is gradually inwards closed under the action of the first inclined plane and the second inclined plane, so that the buckle is separated from the back-off groove, the product is smoothly demolded, and the slide block is pulled back to the initial position under the action of the restoring force of the tension spring due to the fact that the tension spring is arranged at the bottom of the slide block.
