Pressure casting pre-buried type forming device of composite bottom pot

Abstract

A pressure casting pre-buried type forming device of a composite bottom pot comprises a concave die and a convex die. A pot body die is arranged on the convex die. A concave die cavity corresponding to the pot body die is formed in the concave die. A locating groove used for placing a composite bottom sheet is formed in the bottom of the concave die cavity. A magnetic absorbing mechanism used for absorbing the bottom face of the composite bottom sheet is arranged at the bottom of the locating groove. The pressure casting pre-buried type forming device of the composite bottom pot can firmly absorb the whole bottom face of the composite bottom sheet on the surface through the magnetic absorbing mechanism, can conduct circle management and location on the outer circumference wall of the composite bottom sheet through the locating groove, so that locating is firm and reliable, side swing and outward protruding, caused by impact of jet flows, of the composite bottom sheet can be avoided. Moreover, the pressure casting pre-buried type forming device ensures that bottom faces of formed products are smooth and level, and free of inclination and bulge, and greatly improves the product percent of pass. Further, the device is simple in structure and low in manufacture 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.
