Description

Technical Field

[0001] This utility model relates to the field of tire component manufacturing technology, and in particular to a pre-cut plate with replaceable serrations. Background Technology

[0002] Tires are crucial components of vehicles such as cars and trucks. The tire sidewall, as a semi-finished tire part, plays a vital role in transmitting vehicle power and ensuring vehicle safety. The production process of the semi-finished tire sidewall is as follows: the final compounded rubber enters the extruder for plasticization, passes through the die head flow channel and pre-form for pre-compounding, and is then extruded through the die plate to the required size. Due to the influence of tire structural design, tire sidewall dimensions vary. The pre-form can be designed to achieve pre-compounding inside the die head according to different dimensions, ensuring the bonding surface of the soft and hard rubber on the sidewall, as well as the width and thickness of the hard rubber. However, existing pre-form plates require periodic replacement due to rapid wear of the pre-form crease caused by the rubber compound, resulting in a long processing cycle and high processing costs. Therefore, a pre-form plate with replaceable crease creases is proposed. Utility Model Content
