Description

Special mould of shredding knife tackle spare

Technical Field

The utility model belongs to the technical field of the mould and specifically relates to a special mould of cutter unit spare cuts up.

Background

The die is a tool for forming a blank into a product with a specific shape and size under the action of external force. The method is widely applied to blanking, die forging, cold heading, extrusion, powder metallurgy part pressing, pressure casting and the forming processing of compression molding or injection molding of products such as engineering plastics, rubber, ceramics and the like. The die has a specific contour or cavity shape, and the blank can be separated (blanked) according to the contour shape by applying the contour shape with the cutting edge. The blank can obtain a corresponding three-dimensional shape by using the shape of the inner cavity. The mold generally comprises a movable mold and a fixed mold (or a male mold and a female mold), which can be separated or combined. When the blank is closed, the blank is injected into the die cavity for forming.

The shredding knife assembly mainly comprises a main body and a plurality of blades arranged on the main body, wherein the main body is usually arranged on a rotating mechanism, and then the blades are driven to rotate through the mode of rotating the main body so as to shred different articles, and the shredding knife assembly is particularly applied to the fields of juicers and the like.

The existing chopping knife component is produced by injection molding through the most common and widely-applied injection mold. However, the main body of the chopper is a shell structure and is long, and meanwhile, the traditional die cooling structure cannot extend into the main body due to high precision requirement, so that the product quality is affected due to overhigh temperature in the production process.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1 to 5, a special die for a shredding knife assembly comprises an upper die plate 1 and a lower die plate 2, wherein a cavity 3 is arranged in the upper die plate 1, a core 4 is arranged in the lower die plate 2, the cavity 3 and the core 4 are used for producing a shredding knife main body 16, the core 4 comprises a base part 5 located at the lower end and a forming part 6 located at the upper end, and a cooling system 7 is arranged in the core 4. Thereby through the cooling system setting of inside (thus unable this regional cooling of realizing of inside that present cooling is watered and is stretched into core 4), can guarantee to mould plastics the time internal mold core region's of mould continuous cooling, guarantee the quality of moulding plastics.

In this embodiment, the forming portion 6 is a cylindrical structure extending upward, and the cylindrical structure corresponds to the structure inside the main body 16 of the chopping knife, so as to form the cylindrical structure, and meanwhile, the continuous upward extension can ensure that the cylindrical structure is basically distributed in the whole area of the forming portion 6, thereby realizing the continuous cooling of the forming portion 6 and ensuring the injection molding quality of the product.

In this embodiment, the cooling system 7 includes a water channel 8 distributed on the inner wall of the core 4, and the water channel 8 is provided with a water inlet 9 and a water outlet 10. When the cooling water tank is used, water can be supplied through the external water tank, then the water is sequentially drained into the water channel 8 from the water inlet, and the water channel 8 continuously absorbs heat in the inner area of the core 4 in the water flowing process and then is drained from the water outlet 10, so that the cooling effect is achieved.

In the present embodiment, the water passage 9 includes a buffer water passage 11 provided on an inner wall of the base portion 5 and a cooling water passage 13 provided on an inner wall of the molding portion 6. The buffer water channel 11 can ensure the buffer of water entering from the water inlet 9, and the phenomenon that the water is difficult to drain due to the influence of potential force when the water directly enters upwards is prevented, so that the water more stably flows into the cooling water channel 12 to perform the cooling function. Simultaneously play the cushioning effect when the drainage, and then prevent to discharge water too fast because of the influence of power, also played a cushioning effect. The operation of the whole water channel 8 can be very stable, and the continuous cooling function is further ensured.

Preferably, the cooling water channel 12 is serpentine. So that more cooling water channels 12 are arranged in the region of the inner wall of the forming section 6, ensuring that more heat is discharged in the same time and ensuring a better cooling effect.

More preferably, the cooling system 7 is formed integrally with the core 4. The whole water channel 9 is special in shape, so that the whole water channel cannot be machined, and meanwhile, the core 4 has high precision requirement and cooling requirement, so that the arrangement of the cooling system 7 is very critical. Thus, the 3D printing technology can be optimized to integrally form the two, and the requirements are ensured at the same time.

In this embodiment, the lower plate 2 is further provided with a positioning groove 13 for placing the chopping blade 16. Since the chopper blade 16 must be placed in a predetermined area during injection molding so as to be integrally formed with the product after injection molding is completed, the positioning groove 13 ensures accurate positioning of the chopper blade 16.

Preferably, a concave hole 14 is arranged in the positioning groove 13, and a magnet is arranged in the concave hole 14. Because the shredding knife blade 16 can shift and shake to a certain extent in the vertical direction during injection molding, the position of the shredding knife blade 16 relative to the shredding knife main body 15 is influenced, and the overall product quality is influenced, the restriction of the shredding knife blade 16 by the magnet is ensured, and the accuracy of the position of the shredding knife blade 16 relative to the shredding knife main body 15 is ensured.

In this embodiment, the dedicated die of the chopper assembly is a two-station die. Because the overall volume of the chopper assembly is small, two stations can be designed to further improve the production efficiency.

The utility model has the advantages that: through the independent built-in cooling system, the continuous cooling of the inner area of the core during injection molding can be ensured, and the injection molding quality is ensured.

The above embodiment is only one of the preferable embodiments of the present patent, and any changes made without departing from the scope of the present patent are within the scope of the present patent.
