Description

Film forming product

Technical Field

The utility model relates to a Film shaping product belongs to the mould internal injection technical field.

Background

At present, after the existing Film molding, a circle of product is provided with a fillet edge, if direct plastic dripping is carried out, plastic dripping glue easily flows out along the fillet edge, and thus the product is scrapped. In order to solve the problem, a ring of ink stopping ink is printed on the periphery of a plastic dripping area in the plastic dripping process, and then plastic dripping is carried out. However, this method has some disadvantages as follows:

printing prevention ink before Film forming, wherein the position and the shape of the prevention ink are easy to be stretched and deformed during forming, so that a plastic dripping area cannot be fixed, the edge is irregular, the shape difference among products is large, and further the yield is low;

2. printing ink is prevented after Film forming, a special printing jig which is copying to a formed product needs to be additionally manufactured, and the production cost of an enterprise is increased.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome not enough among the prior art, provide a Film shaping product that yield is high, low in production cost, can solve among the prior art product and drip the easy excessive technical problem of plastic process plastic drip.

In order to solve the technical problem, the utility model discloses an adopt following technical scheme to realize:

a Film forming product comprises a product body, wherein the product body is provided with a plastic dripping area, the periphery of the plastic dripping area is surrounded with a convex edge, and the convex edge protrudes out of the surface of the plastic dripping area; when the plastic is dripped, the convex edge can prevent the dripping plastic from overflowing the dripping plastic area, and the dripping plastic film formed after the plastic is dripped is connected with the convex edge in a smooth transition manner.

Furthermore, the convex edge comprises an outer side surface, an inner side surface and a top surface connected between the outer side surface and the inner side surface, and the outer side surface is flush with the outer vertical surface of the product body; the inner side surface of the convex ridge is vertical to the surface of the plastic dripping area.

Furthermore, the convex edge and the product body are integrally formed.

Furthermore, the vertex angle that top surface and lateral surface, medial surface formed is the arc.

Furthermore, the height of the convex edge is 0.15-0.40mm, and the width of the convex edge is 0.25-0.50 mm.

Furthermore, the thickness of the drip molding film is 1.5-2.0 mm.

Furthermore, the plastic dripping area is arranged on the front surface of the product body.

Compared with the prior art, the utility model discloses the beneficial effect who reaches:

the utility model discloses a Film shaping product adopts and to drip that to mould the district periphery and set up the protrusion and replace the prevention printing ink among the prior art in dripping the bead that moulds the district surface, not only can prevent to drip that the plastic is excessive, improve the yield, and can drip at the product and mould the in-process and remove prevention printing ink printing process from, has simplified and has dripped the technology of moulding, reduces the manufacturing cost of enterprise, has improved production efficiency.

FIG. 2 is a schematic view of the structure of the ribs of the Film molded product of FIG. 1;

in the figure: 1. a product body; 2. a rib; 21. an outer side surface; 22. a top surface; 23. an inner side surface; 3. a plastic dripping area.

Detailed Description

The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

An embodiment of the utility model provides a Film forming product, this Film forming product can be suitable for injection molding processes such as IML, IMD, can be widely used in communication products (for example: cell-phone/xiaolingtong lens, decoration, shell etc.), domestic appliance (window panel, button panel, decoration panel etc.), medical equipment (window lens, casing, decoration etc.) and motormeter dish etc..

As shown in fig. 1 and fig. 2, the Film molded product comprises a product body 1, wherein the product body 1 is provided with a plastic dripping area 3, the periphery of the plastic dripping area 3 is provided with a rib 2, and the rib 2 protrudes out of the surface of the plastic dripping area 3; when plastic is dripped, the convex edge 2 can prevent the dripping plastic from overflowing, and the yield is improved; the plastic dripping area 3 is connected with the convex edge 2 in a smooth transition way after plastic dripping, and the appearance effect is not influenced.

The utility model discloses Film shaping product's surface can directly drip to mould, drips to mould the back neat, and the shape is unified, and the boundless is looked to the eye, can strengthen the outward appearance of product and beautify, does benefit to batch production.

In order to reduce the production process, the convex edge 2 of the Film forming product and the product body 1 can be integrally formed, and can be directly processed and formed by adopting a mould. As an equivalent deformation, the rib 2 and the product body 1 can also adopt a split design structure, but the rib 2 should be fixedly and hermetically connected with the product body 1 to prevent the dripping plastic from overflowing.

In this embodiment, bead 2 includes lateral surface 21, medial surface 23 and connects the top surface 22 between lateral surface 21 and medial surface 23, and the apex angle that the top surface 22 of bead 2 and lateral surface 21, medial surface 23 formed is the arc, and wherein, lateral surface 21 flushes mutually with the outer facade of product body 1, and the medial surface 23 of bead 2 is perpendicular with the 3 surface facies in the district that moulds dropwise to form better outside visual effect. It will be understood that the main function of the ribs 2 is to prevent the drip gum from flowing over the drip-moulding zone, and therefore the shape of the ribs 2 is not limited thereto, for example: the bead 2 can also be a rib structure with a triangular or semicircular cross section, and the protection scope of the utility model is to be regarded as if the protruding structure can prevent the plastic dripping glue from overflowing the plastic dripping area.
