Die-casting pre-buried molding device for compound bottom pot

Abstract

A die-casting pre-embedded molding device for a double-bottomed pot, comprising a die and a punch, the punch is provided with a pot model, and the die is provided with a concave cavity corresponding to the pot model, the The bottom of the concave mold cavity is provided with a positioning groove for placing the composite film, and the bottom of the positioning groove is provided with a magnetic attraction mechanism for absorbing the bottom surface of the composite film. On the one hand, the forming device of the present invention firmly absorbs the entire bottom surface of the composite film on its surface through the magnetic suction mechanism, and on the other hand, it also performs full-circle positioning on the outer peripheral wall of the compound film through the positioning groove, so the positioning is firm and reliable, and can avoid Under the impact of the jet, the compound film will appear sideways and convex, which ensures that the bottom surface of the product after molding is smooth and flat, without inclination and bulge, which greatly improves the qualified rate of the product. In addition, the device has a simple structure and low manufacturing cost.

Description

Technical field: [0001] The invention relates to the field of manufacturing double-bottomed pots, in particular to a die-casting embedded molding device for double-bottomed pots. Background technique: [0002] Because the pure aluminum material pot can't be used on the induction cooker, so there has been a stainless iron or stainless steel double bottom pot in the prior art to replace. [0003] Chinese invention patent CN101352753B discloses a die-casting mold for a double-bottom pot, which includes a fixed mold and a movable mold. The inner surface of the fixed mold is provided with a pot body model, an aluminum liquid injection port, and positioning seats symmetrically arranged on both sides of the pot body model. The two positioning seats are respectively connected with the cylinder on the outside, and slide inward and outward according to the reciprocating motion of the cylinder. The inner side of the movable mold has a first concave cavity matched with the pot body mode...

AI Technical Summary

Problems solved by technology

The die-casting mold can make the die-cast double bottom pot have the advantages of firm connection and no seam on the bottom surface, etc., but it also has the following disadvantages: first, the double bottom plate is positioned on both sides, and the positioning is not firm. Under the impact of the jet, Not only is it easy to cause sideways swing of the compound film, causing the bottom surface of the product to be inclined, but it may also cause the middle part of the compound film to bulge outward, resulting in a bulge on the bottom surface of the product after forming, which will lead to product scrapping and affect the product. The second is that the two positioning seats used to realize the positioning of the composite film need to be equipped with cylinders, slide rails, ventilation pipes, etc. to control their internal and external sliding, which not only has a complex structure, but also increases the equipment cost.
