Abstract

The utility model discloses a rubber track decorative pattern forming die with decorative pattern wire blocking groove. The novel casting mold comprises a lower mold with a plurality of pattern forming cavities and an upper mold capable of being matched with the lower mold to form a whole molding mold body, wherein a plurality of main exhaust grooves which are longitudinally arranged in parallel along the pattern forming cavities are arranged on the upper surface of the lower mold, an annular blocking groove is arranged at the edge inside each pattern forming cavity, and the depth of the blocking groove is deeper than that of the main exhaust grooves, so that a casting material poured in the pattern forming cavities can be blocked. After the structure is adopted, on the basis of not changing the structure of the whole forming die body, the blocking groove is skillfully formed at the inner edge of the pattern forming cavity, so that in the forming process, the blocking groove can be used for blocking the casting material in the pattern forming cavity without influencing the air permeability, thereby thoroughly avoiding the hair generated at the periphery of the cavity after the pattern is formed, greatly improving the surface smoothness and the attractiveness of the product and effectively ensuring the quality of the product.

Description

Rubber track decorative pattern forming die

Technical Field

The utility model relates to a rubber track production mould, specifically speaking are rubber track decorative pattern forming die with decorative pattern wire blocking groove.

Background

In the production process of the rubber track, the pattern forming needs a special pattern forming die, in the prior art, an exhaust groove needs to be designed in the pattern forming process, casting materials are poured in the pattern forming die in the production process, however, the edge of the pattern has hair after pouring and forming due to the existence of the exhaust groove, so that on one hand, the hair needs to be manually removed due to the attractiveness of the product, and therefore, the labor is wasted, and on the other hand, even if the hair is removed, the pattern surface is still not smooth and clean, and the smoothness of the product surface is further influenced.

Disclosure of Invention

The to-be-solved technical problem of the utility model is to provide a rubber track decorative pattern forming die that can avoid producing the hair after the decorative pattern shaping and must and improve product surface smoothness nature.

In order to solve the technical problem, the utility model discloses a rubber track decorative pattern forming die, including the lower mould that has a plurality of decorative pattern shaping chambeies and can with the lower mould to closing the last mould that forms whole shaping die body, the upper surface of lower mould is arranged many along the main exhaust duct that the vertical parallel of decorative pattern shaping chamber was arranged, and every decorative pattern shaping intracavity portion edge all is provided with the annular groove that blocks, thereby the degree of depth that blocks the groove is dark in the degree of depth of main exhaust duct can block the pouring material of pouring in the decorative pattern shaping intracavity.

The depth of the main exhaust groove is 1-1.5mm, and the depth of the blocking groove is 2-2.5 mm.

The width of the main exhaust groove is 1-1.5mm, and the width of the blocking groove is 1.5-2 mm.

The lower die is provided with a left row of pattern forming cavities and a right row of pattern forming cavities, and the left row of pattern forming cavities and the right row of pattern forming cavities are arranged in a staggered mode.

The main exhaust groove longitudinally penetrates through each pattern forming cavity.

And the lower die is also provided with auxiliary exhaust grooves positioned at the outer side edges of the pattern forming cavities.

After the structure is adopted, the main exhaust grooves which are arranged on the upper surface of the lower die in parallel along the longitudinal direction of the pattern forming cavity and the annular blocking grooves of which the depth is greater than that of the main exhaust grooves are arranged on the inner edge of each pattern forming cavity, so that the blocking grooves are ingeniously formed on the inner edge of the pattern forming cavity on the basis of not changing the structure of the whole forming die body, therefore, in the forming process, the blocking grooves can be used for blocking the casting material in the pattern forming cavity without influencing the air permeability of the casting material, the burrs generated after the pattern forming are thoroughly avoided, the surface smoothness of the product is greatly improved, and the quality of the product is effectively ensured.

Detailed Description

The following describes the rubber track pattern forming mold in detail with reference to the accompanying drawings and the following detailed description.

As shown in the figures, the rubber track pattern forming mold of the present invention comprises a lower mold 2 having a plurality of pattern forming cavities 1 and an upper mold 4 capable of being involutively combined with the lower mold to form a whole forming mold body 3, wherein a plurality of main exhaust grooves 5 are arranged on the upper surface of the lower mold 2 and arranged in parallel along the longitudinal direction of the pattern forming cavities 1, the longitudinal direction is the direction shown in fig. 2, specifically the length direction of the lower mold, and can also be defined as the front-back direction in fig. 2, it can be understood that the width direction of the lower mold is defined as the left-right direction at this time, as can be seen from fig. 2, the main exhaust grooves 5 longitudinally penetrate through the pattern forming cavities, the inner edge of each pattern forming cavity 1 is provided with an annular blocking groove 6, as can be clearly seen from fig. 3, the inner edge position of each pattern forming cavity 1 is formed with a blocking groove (because of the exhaust grooves, there, therefore, the blocking groove may be referred to as a wire blocking groove) 6, the depth of the blocking groove 6 is deeper than the depth of the main exhaust groove to block the castable poured into the pattern forming cavity 1, preferably, the depth of the main exhaust groove 5 is 1-1.5mm, the depth of the blocking groove 6 is 2-2.5mm, the depth of the main exhaust groove 5 is preferably 1.5mm, and the depth of the blocking groove 6 is preferably 2.5 mm. The width of the air discharge groove 5 is 1-1.5mm, and the width of the blocking groove 6 is 1.5-2mm, of course, the width of the air discharge groove 5 is preferably 1mm, and the width of the blocking groove 6 is preferably 2 mm.

Furthermore, the lower die 2 is provided with a left row of pattern forming cavities and a right row of pattern forming cavities 1, the left row of pattern forming cavities and the right row of pattern forming cavities 1 are arranged in a staggered mode, in addition, the lower die 2 is also provided with auxiliary exhaust grooves positioned on the outer edges of the pattern forming cavities, and certainly, as the blocking grooves are of an annular structure, the pouring materials are blocked from flowing out of the auxiliary exhaust grooves, and the blocking effect is further improved.

Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and the changes, modifications, additions, arrangements or replacements of patterns made by those skilled in the art within the scope of the present invention shall also belong to the protection scope of the present invention.
