Problems solved by technology

Iron lagging parts are common metal lagging parts. Due to the mass production of iron lagging parts, there must be differences in their size within a certain range, so the size of the mold core is not easy to control, which leads to poor lagging effect

Embodiment Construction

[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0016] see Figure 1-4 As shown, an auxiliary overmolding component 1 is used in a mold, and the mold includes an upper template 2, a lower template 3 located below the upper template 2, and a mold core 4 between the upper template 2 and the lower template 3, the auxiliary package The rubber part is arranged in the mold core 4, which includes a threaded body 11, a spring 12, and a steel ball 13. The outer surface of the threaded body 11 is provided with a threaded structure, and one end thereof is provided with a first blind hole 11a. A spring 12 and a steel ball 13 located at one end of the spring 12 are provided. Part of the outer surface of the steel ball 13 protrudes from the first blind hole 11a. When the steel ball 13 is subjected to an external force and the spring 12 i...

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...
