Description

Sole mould that interior benevolence flicked downwards

Technical Field

The utility model relates to a sole mould technical field especially relates to a sole mould that interior benevolence bounces downwards.

Background

The mould is various moulds and tools for obtaining required products by injection molding, blow molding, extrusion, die casting or forging forming, smelting, stamping and other methods in industrial production. In short, a mold is a tool used to make a shaped article, the tool being made up of various parts, different molds being made up of different parts, the molds having a very important role in the field of footwear making technology.

The sole is processed by injection molding in a molding cavity of a mold, and then the mold is opened to take out the molded sole. As shown in figure 1, a TPU injection molded sole A is provided, a ring of barbed rubberized surface A1 is formed inside the sole A, and the rubberized surface A1 facilitates the sole to be adhered to the midsole and the upper more firmly. However, when the sole with such a structure is injection molded, as shown in fig. 2, the barbed rubberized surface a1 is embedded in the inner core B (the thin-walled barb of the sole rubberized surface is on the inner core), so that great effort is required to pull out the sole, and the rubberized surface is easily broken in the pulling-out process, thereby causing damage to the sole and increasing the rejection rate.

Disclosure of Invention

In view of this, an object of the present invention is to provide a sole mold with an inner shell springing downward, so that a sole can be easily and smoothly taken off from the mold, a sole adhesive surface does not form a mold release obstacle, and a finished product yield of the sole is high.

In order to achieve the above purpose, the utility model adopts a sole mold with an inner core which is flicked downwards, comprising a bottom mold, side molds arranged at two sides of the bottom mold, and an upper sealing plate arranged above the side molds, wherein the upper sealing plate is provided with an inner core mold core, the inner core mold core comprises a first inner core fixed on the upper sealing plate and a second inner core movably connected on the first inner core, a plurality of guide rods are connected between the first inner core and the second inner core, one end of each guide rod is fixed on the second inner core, the other end of each guide rod is movably connected on the first inner core, springs are arranged on the guide rods in a penetrating way, the edge of the first inner core just facing the second inner core or the edge of the second inner core just facing the first inner core form a concave edge, the middle part of the second inner core forms a connecting part towards the bulge of the first inner core, one end of the connecting part close to the upper sealing plate respectively extends towards the side molds at two sides to form a pushing plate, the position of the side mold corresponding to the pushing plate forms a groove matched with the pushing plate, the kernel removes to the kernel laminating each other in making first interior kernel and second along with the cooperation of slurcam and recess in the second, the position of the closed back concave edge of kernel constitutes rubberizing face shaping chamber in first interior kernel and the second, constitute an inclosed sole shaping chamber between die block, side forms, last shrouding and the interior kernel mold core.

The use mode of the sole mould with the inner core bouncing downwards is as follows: firstly, covering an upper sealing plate on a bottom die, fastening a die lock, then closing side dies on two sides, supporting a pushing plate by a groove on the side dies to ascend, enabling a second inner core to be attached to a first inner core, compressing a spring, and injecting a high-temperature thermoplastic material into a sole forming cavity until the sole forming cavity is full of the high-temperature thermoplastic material and the rubberized surface forming cavity is full of the high-temperature thermoplastic material; after the inside high temperature thermoplastic material shaping, loosen the mould lock, open shrouding and side forms on, after the kickboard lost the effort of side forms to it, bounce down under the effect of spring and reset to initial position, benevolence separation back in first interior benevolence and the second, the rubberizing face of sole just can not closely connect in rubberizing face shaping intracavity, just so can take off sole from last interior benevolence simply, smoothly. The utility model discloses the sole mould that interior benevolence was flicked downwards produces ascending thrust to benevolence in the second when utilizing the side forms to merge, makes benevolence laminate each other in first interior benevolence and the second, constitutes rubberizing face shaping chamber, makes the sole can the shaping play rubberizing face, separates from first interior benevolence in opening sole mould back second, the sole drawing of patterns of being convenient for to realize quick drawing of patterns, the sole finished product qualification rate that obtains is high moreover.

This practicality further sets up to the middle part formation activity stroke chamber of benevolence in first, the slurcam setting is in the activity stroke intracavity.

The movable stroke cavity of the first inner core provides abdication for the pushing plate, and the second inner core is enabled to stably act on the first inner core.

This practicality further sets up to the both sides limit that the slurcam is close to the recess and all forms arc chamfer.

The arc-shaped chamfer is convenient for linkage matching with the pushing plate when the side die is closed, so that the closing action of the side die is smoother.

This practicality further sets up to the concave edge setting in the second benevolence just to the edge of benevolence in the first.

The concave edge is arranged on the second inner core, so that demolding of the sole is facilitated.
