Abstract

The invention discloses an auxiliary rubber coating assembly which is characterized in that the auxiliary rubber coating assembly is arranged in a mould core of a mould; the auxiliary rubber coating assembly comprises a thread body, a spring and a steel ball; a thread structure is arranged on the external surface of the thread body; a first blind hole is formed at one end of the thread body; the spring and the steel ball positioned at one end of the spring are mounted in the first blind hole; and a part of the external surface of the steel ball protrudes out of the first blind hole. When the mould core is coated with a rubber coating piece, the rubber coating piece pushes against the steel ball of the auxiliary rubber coating assembly, the spring is compressed, the steel ball retracts back, and a counter-acting force of the spring acts on the rubber coating piece simultaneously to allow the steel ball and the rubber coating piece to be clamped with each other. In this way, the auxiliary rubber coating assembly can remove dimensional variation between the varisized rubber coating pieces and the mould cores, thereby achieving a better rubber coating effect. In addition, a contact area between the steel ball and the rubber coating piece is less, thereby facilitating taking products.

Description

technical field

[0001] The invention relates to an auxiliary rubber-covering component, which belongs to the field of molds. Background technique

[0002] TPE glue sticking can be divided into real glue and fake glue. True encapsulation utilizes the compatibility of soft and hard rubber when softened and melted to form a bonding layer on the contact surface of hard and soft rubber to improve the encapsulation adhesion between soft and hard rubber. False lagging hardly involves the compatibility of the two materials. The lagging of the material is through mechanical force, through the design and surface treatment of the mold and product, and through the hooping effect, so that the soft rubber and the hard rubber can be joined together. .

[0003] The hard materials commonly used for fake lagging are mainly plastic, metal and woven cloth. False overmolding generally adopts the secondary injection molding process, that is, the injection-molded hard parts are fixed on the ove...
