Abstract
The rubber tire injection mold with the middle ring comprises an upper mold, the middle ring and a lower mold, wherein an injection hole is formed in the upper mold, and the middle ring is movably arranged between the upper mold and the lower mold. The advantage lies in, well, last mould and lower mould three compound die, through last injection hole on the mould with raw materials injection to injection appearance intracavity, the shaping structure of well ring is located the injection appearance intracavity, just can't fill shaping structure position during the rubber raw materials injection to the shaping is accomplished, has just formed a hollow structure, practices thrift the cost promptly, has shortened the vulcanization time again, convenient operation, great improvement efficiency.
Description
Technical Field
The invention relates to a rubber injection mold, in particular to a rubber tire injection mold with a middle ring.
Background
The rubber injection mold is a common device for manufacturing rubber products, rubber raw materials are injected into the mold and vulcanized at high temperature to manufacture the rubber products according to the shape of a cavity in the mold.
The tire is one of the widely used rubber products, and most of the rubber tires with smaller size are manufactured by rubber injection to form solid tires, but the solid tires consume materials and increase the cost, and the processing procedure is complicated and time-consuming.
Disclosure of Invention
In order to solve the problems, a rubber tire injection mold with a middle ring is specially made, which is suitable for producing small hollow rubber tires.
In order to achieve the above purpose, the invention is solved by the following technical scheme: the rubber tire injection mold with the middle ring comprises an upper mold, the middle ring and a lower mold, wherein an injection hole is formed in the upper mold, and the middle ring is movably arranged between the upper mold and the lower mold.
Furthermore, the upper die is also provided with an injection hole, after the upper die and the lower die are assembled, the upper die and the lower die form an injection cavity, and the injection hole is communicated with the injection cavity.
Further, the middle ring comprises a fixed table board and a molding structure, a boss is arranged on the lower die, the fixed table board is clamped on the boss, and the molding structure is located in the injection containing cavity.
Furthermore, the upper die is also provided with a vacuum hole.
Furthermore, the upper die is also provided with a tearing groove which is arranged on the periphery of the injection cavity.
The invention has the advantages that:
in the mould of the original injection moulding tyre, a middle ring is added, the middle ring is relatively independent from an upper mould and a lower mould, when the solid tyre needs to be produced and manufactured, the middle ring is taken out, and the upper mould and the lower mould are closed to mould. When the hollow tire needs to be produced and manufactured, the middle ring is placed between the upper die and the lower die, the middle ring, the upper die and the lower die are assembled, raw materials are injected into the injection containing cavity through the injection hole in the upper die, the forming structure of the middle ring is located in the injection containing cavity, and the forming structure cannot be filled when the rubber raw materials are injected, so that the forming is completed, the hollow structure is formed, the cost is saved, the vulcanizing time is shortened, the operation is convenient, and the efficiency is greatly improved.
Drawings
FIG. 1 is a schematic structural view of a rubber tire injection mold with a middle ring according to the present invention.
Reference numerals: the device comprises an upper die 1, a lower die 2, a middle ring 3, an injection hole 4, a vacuum hole 5 and a tearing groove 6.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
An injection cylinder of a rubber tire injection mold with a middle ring 3 comprises an upper mold 1, a middle ring 3 and a lower mold 2, wherein an injection hole 4 is formed in the upper mold 1, the middle ring 3 is movably arranged between the upper mold 1 and the lower mold 2, when a molded small tire product is manufactured, the upper mold 1 and the lower mold 2 are assembled, a cavity formed by the upper mold 1 and the lower mold 2 is a basic structure of the tire appearance, and if a rubber raw material is injected into the mold through the injection hole 4 under the condition that the middle ring 3 is not arranged, a solid small rubber tire can be molded and vulcanized at high temperature.
The middle ring 3 is additionally arranged between the upper die 1 and the lower die 2, and the middle ring 3 is designed on the basis of the original die, so that the middle of a product is hollowed, and the hollowed part is the hollow structure of the rubber tire.
During injection molding, the upper mold 1, the middle ring 3 and the lower mold 2 are firstly closed, after closing, the mold is pressurized, then vacuum treatment is carried out in the mold through the vacuum hole 5, and injection molding in a vacuum environment can avoid the condition that bubbles exist in an injection finished product, so that the quality of the injection molded product is further improved. After the injection machine is in place, injecting rubber raw materials into the mold through the injection hole 4 in the upper mold 1, injecting the redundant parts of the raw materials while injecting the rubber raw materials, enabling the rubber raw materials to enter the tearing groove 6, separating the upper mold 1, the middle ring 3 and the lower mold 2 after high-temperature vulcanization is completed, taking out the finished tire product and the middle ring 3 together through a tearing strip formed in the tearing groove 6, and then taking out the middle ring 3 from the finished tire product. Finally, the surface of the tire is processed, and the tearing strip is removed, so that the finished product is processed.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and it is therefore intended that the present embodiments be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
