Abstract
The utility model relates to an injection mold of one-mold multi-part variety. The injection mold comprises a fixed template and a movable template matched with the fixed template, and is characterized in that a sprue is positioned in the middle of the fixed template; more than three cavities in different shapes are formed on the fixed template; each cavity is communicated with the sprue through a respective cross gate; a cavity lug of which the shape is the same as that of each cavity on the fixed template is arranged on the movable template; when the movable template is fastened on the fixed template, each cavity lug is arranged in a corresponding cavity; and a feeding hole formed on the side of each cavity lug is communicated with the respective cross gate. Multiple parts in different shapes are simultaneously injected on the same mold, the injection molding efficiency can be improved, and the production efficiency and equipment utilization rate are improved.
Description
Technical field
The utility model relates to a kind of injection mold of many parts of mould kind, belongs to the injection mold technical field.
Background technology
Injection moulding class part is by being made by injection mold.Injection mold comprises solid plate and the moving platen that matches with solid plate, solid plate is provided with cast gate, also be provided with die cavity and cross gate on the solid plate, die cavity communicates with cast gate by cross gate, and when moving platen is fastened on the solid plate, die cavity projection on the moving platen is arranged in the die cavity of cover half piece, because running channel communicates with the die cavity projection, therefore with in the material feeding injection die cavity projection of melting and outpour required injection-moulded plastic part.At present injection mold only is provided with a kind of die cavity and for a kind of part, perhaps a secondary injection mold is provided with a plurality of die cavities simultaneously usually, but a plurality of die cavity is the shape a kind of part identical with structure.And the part of and difformity and structure relatively simple for structure need to remove to develop a secondary injection mold for each part, therefore can cause the relative waste of resource, and injection mo(u)lding efficient is low, also can affect productive temp simultaneously.
Summary of the invention
The purpose of this utility model provides a kind of a plurality of difformities and constitutional detail of injecting simultaneously, improves the injection mold of many parts of mould kind of injection mo(u)lding efficient.
The utility model for the technical scheme that achieves the goal is: a kind of injection mold of many parts of mould kind, comprise solid plate and the moving platen that matches with solid plate, it is characterized in that: be positioned at the middle part on the described solid plate and be provided with cast gate, solid plate is provided with variform die cavity more than three, and each die cavity communicates with cast gate by cross gate separately; Described moving platen is provided with the die cavity projection identical with each cavity shape on the solid plate, and its each die cavity projection was arranged in the corresponding die cavity when moving platen was fastened on the solid plate, is arranged on the charging aperture of each die cavity nub side section and communicates with separately cross gate.
This practicality newly is provided with variform die cavity more than three at solid plate, each die cavity passes through cross gate and cast gate phase flow-through separately, simultaneously, be provided with the die cavity projection identical with each cavity shape on the solid plate at moving platen, the charging aperture of each die cavity nub side section communicates with cross gate separately, therefore can be injected in each die cavity projection by each crossbeam road by the material feeding of a cast gate with melting, realize a plurality of relatively simple and shape parts different with structure, can realize simultaneously injection mo(u)lding at same mould, enhance productivity and utilization rate of equipment and installations, also be conducive to the production control beat.The utility model solid plate is sprue from its running channel of die cavity away from the cast gate, solid plate is the shaped form running channel from its running channel of die cavity close to the cast gate, or the cross gate diameter that communicates with the large die cavity of area on the solid plate is greater than the cross gate diameter that communicates with the little die cavity of area, so can control the mobile balance of fluid injection of telling from cast gate, reach synchronous injection moulding and finish.
