Abstract

Disclosed is a new backlight source lens mold with 256 cavities in one mold, the backlight source lens mold comprising a mold, wherein the mold is composed of 32 groups of product areas; each group of product areas is composed of eight molding cavities with an annular array design structure; the centre of each group of product areas is provided with an adhesive inlet; the interior of each group of product areas is provided with an adhesive inlet channel; thirty-two adhesive inlets and thirty-two adhesive inlet channels are provided; and the thirty-two groups of product areas are independent from one another and not in communication with one another. The new backlight source lens mold with 256 cavities in one mold of the present utility model is provided with thirty-two adhesive inlets and thirty-two adhesive inlet channels, so that each product sub-area has one separate adhesive inlet so as to effectively ensure the balance of a product during injection moulding and quality stability, and each product sub-area has an adhesive inlet channel so as to reduce the drainage opening material and correspondingly shorten the product formation cycle. The present utility model has a certain practicality, bringing about a better usage prospect.

Description

Novel one-mode 256-cavity backlight lens mold

Technical field

The utility model relates to the field of molds, in particular to a novel one-mold 256-cavity backlight lens mold.

Background technique

Molds are molds and tools for processing required products, which are widely used in various fields. Backlight lens molds are also a type of molds, which belong to injection molds. Depending on the number of cavities, different processing requirements can be achieved. The existing 192 cavities cannot meet them. People's use; the existing backlight lens molds have certain disadvantages in use. First of all, it cannot meet the need for a separate glue inlet for each sub-product area, which cannot guarantee the balance of the product during injection, and the quality stability is affected. Limitation. Secondly, it cannot meet the requirement that each sub-product area has a glue-feed channel. The glue-feed channel is longer, the nozzle material cannot be reduced, the product molding cycle is long, and it has a certain impact on production capacity and cost. We propose a new type of one-mold 256-cavity backlight lens mold.

Utility model content

The main purpose of the utility model is to provide a novel one-mold 256-cavity backlight lens mold, which can effectively solve the problems in the background technology.

To achieve the above purpose, the technical scheme adopted by the present utility model is:

A new type of one-mold 256-cavity backlight lens mold includes a mold, the mold is composed of thirty-two groups of product areas, and each group of product areas is composed of eight cavities in a circular array design structure. The center of the product area is provided with a glue inlet, and the inside of each product area is provided with a glue inlet flow channel.

Preferably, the number of the rubber inlets and the rubber inlet channels are thirty two groups.

Preferably, each of the thirty-two sets of product areas is independent and not connected.

Preferably, the glue inlet flow channel is located directly below the glue inlet.

Preferably, the glue inlet corresponds to the glue inlet flow channel and the product area one-to-one.

Compared with the prior art, the utility model has the following beneficial effects: The new one-mold 256-cavity backlight lens mold can meet the needs of each sub-product area with a separate plastic inlet through the thirty-two groups of plastic inlets provided. It can effectively ensure the balance and quality stability of the product during injection molding. Through the set of thirty-two sets of feeding channels, each sub-product area can have one feeding channel, which will shorten the feeding channel and achieve nozzle material. Reduced, the product molding cycle is correspondingly shortened, effectively increase production capacity, reduce injection molding costs, has a certain practicability, the entire new one-mold 256-cavity backlight lens mold is simple in structure, easy to operate, and the effect is better than the traditional method.

detailed description

In order to make it easy to understand the technical means, creative features, objectives and effects achieved by the present utility model, the present utility model is further described below in combination with specific embodiments.

As shown in Figure 1-2, a new type of one-mold 256-cavity backlight lens mold includes mold 1, mold 1 is composed of thirty-two groups of product areas 2, and each group of product areas 2 is composed of eight circular arrays. The cavity 3 is composed of a rubber inlet 4 in the center of each product area 2 and a rubber inlet 5 in each product area 2; the number of the rubber inlet 4 and the rubber inlet 5 are both Thirty-two groups and thirty-two groups of product areas 2 are independent and not connected. The rubber inlet flow channel 5 is located directly below the rubber inlet 4, and the rubber inlet 4 corresponds to the rubber inlet channel 5 and the product area 2 one-to-one.

It should be noted that this utility model is a new type of one-mold 256-cavity backlight lens mold. In use, first, the mold 1 is placed on the required injection molding table, and the injection molding raw materials pass through thirty-two groups of plastic inlets. 4 Enter the thirty-two groups of product areas 2 that are independent and not connected. Each group of product areas 2 has a separate rubber inlet 5, and the more rubber inlets 5, the more balanced the product can be during injection molding. The higher the quality stability, the thirty-two sets of rubber feed channels 5 set inside the thirty-two product zone 2 can satisfy each product zone 2 with one rubber feed channel 5, thereby making the rubber feed channel 5 shorter. It is more practical to reduce the nozzle material and shorten the molding cycle of the product, which effectively increases the production capacity and reduces the injection molding cost.

The basic principles and main features of the present invention and the advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited by the foregoing embodiments. What is described in the above embodiments and the description merely illustrates the principle of the present invention.
