Abstract
The utility model discloses an injection molding rubber coating mould, its front mould have rubber coating face and non-rubber coating face, a breach is seted up to non-rubber coating face, makes the sizing material overflow to breach temporary storage, has stopped the rubber coating and has draped over one's shoulders cutting edge of a knife or a sword, saves and need handle and draped over one's cutting edge of a knife or a sword process, guarantees that the non-rubber coating face of gluing of product is smooth pleasing to the eye.
Description
Technical Field
The utility model belongs to injection mold specifically relates to an injection molding rubber coating mould.
Background
At present, the plastic product is encapsulated by an encapsulating mold, which is a common molding method in the mold industry, and the encapsulating mold is an injection molding process for combining a thermoplastic elastomer to the surface of the plastic product through melt adhesion so as to meet the use requirement or the requirement of attractive appearance. Similarly, taking an injection molding handheld remote controller product as an example, the structure of the injection molding handheld remote controller product is composed of a framework for supporting and an encapsulating layer with anti-skid lines for handheld holding feeling, wherein usually, a hard glue framework is firstly injected and then placed in an encapsulating mold for injection molding again, so that the surface of the hard glue framework is coated with a layer of soft glue. However, due to the influence of the processing precision of the mold, the encapsulation mold has two defects in the encapsulation process: 1. the glue is easy to overflow, so that burrs exist at the joint of the encapsulating layer and the framework layer; 2. the non-encapsulated surface is easily damaged by the die, which affects the beauty.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide an effective drainage overflows to glue, the smooth rubber coating mould of moulding plastics of outward appearance.
In order to solve the technical problem, the utility model discloses a technical scheme be: the injection molding encapsulation mold comprises a front mold and a rear mold, wherein the front mold is provided with an encapsulation surface and a non-encapsulation surface, and the non-encapsulation surface is provided with a notch.
Preferably, the depth of the notch is 0.05-0.2 mm.
Preferably, an art wire groove is arranged at the boundary of the rubber coating surface and the non-rubber coating surface.
By implementing the technical scheme, the non-encapsulation surface is provided with the notch, so that the rubber material overflows to the notch for temporary storage, the encapsulation flash is avoided, the flash processing procedure needing to be processed is omitted, and the smoothness and the attractiveness of the non-encapsulation surface of the product are ensured.
Drawings
Fig. 1 is a schematic structural diagram of an injection molding and encapsulation mold.
Fig. 2 is a partially enlarged view of a portion a in fig. 1.
Detailed Description
The following describes the present invention with reference to the accompanying drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
As shown in fig. 1 and 2, the injection and encapsulation mold is mainly composed of a front mold 1 and a rear mold 2. A product framework 3 is arranged between the front mould 1 and the rear mould 2, and an injection molding glue coating layer 4 is arranged between the front mould 1 and the product framework 3.
The front die 1 is divided into a rubber coating surface 1.1 and a non-rubber coating surface 1.2, a gap 5 is formed in the non-rubber coating surface, a gap is formed between the gap 5 and a product framework to serve as a clearance, and the distance between the gaps is 0.1 mm.
The edge of the encapsulating layer 4 positioned at the boundary of the encapsulating surface 1.1 and the non-encapsulating surface 1.2 is provided with an art wire slot 6, and the interference encapsulation is adopted to prevent glue leakage. The interference seal glue is collected at the position of the art wire groove, the parting surface of the die is 0.2mm higher, and the die is in interference fit during die assembly.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is to be accorded the full scope of the claims.
Claims (2)
1. The utility model provides an injection moulding rubber coating mould, includes front mould and back mould, and the front mould has rubber coating face and non-rubber coating face, its characterized in that: the non-encapsulation surface is provided with a gap; and an art wire groove is arranged at the boundary of the rubber coating surface and the non-rubber coating surface.
2. The injection molding encapsulation mold of claim 1, wherein the depth of the notch is 0.05 to 0.2 mm.
