Abstract

The utility model discloses an injection mold. The injection mold comprises a first mold core and a second mold core which are buckled together, wherein at least one shallow groove runner with shallow depth and a plurality of cavities which are wholly or partially positioned in the runner groove are enclosed between the first mold core and the second mold core. The utility model discloses injection mold encloses synthetic shallow slot runner between first mould benevolence and the second mould benevolence and couples together a plurality of die cavities to the runner design has been simplified, and it is more convenient to make this injection mold design, make, thereby can improve production efficiency.

Description

injection mold

technical field

The utility model relates to an injection mold, in particular to an injection mold with one cavity and multiple cavities.

Background technique

Injection molding is a production method widely used in industry at present. In the structural design of injection molds, core and cavity are key components. At present, the design of the core and the cavity generally depends on the size of the product. The product is simple and small in size and can be designed as a mold with multiple cavities.

In the existing injection molds, the flow channel structure usually needs to be designed to be very complicated between multiple cavities, which brings difficulties to mold manufacturing and is not conducive to improving production efficiency.

Utility model content

The purpose of the utility model is to provide an injection mold which can improve production efficiency and is easy to manufacture.

In order to achieve the above object, the injection mold provided by the utility model includes a first mold core and a second mold core that are fastened together, and at least one shallow groove with a shallower depth is formed between the first mold core and the second mold core. A runner and a number of cavities that are wholly or partially located in the runner groove.

As mentioned above, the injection mold of the utility model connects several cavities through the shallow groove flow channel formed between the first mold core and the second mold core, thereby simplifying the design of the flow channel and making the design and manufacture of the injection mold more convenient. Convenience, which can improve production efficiency.

Detailed ways

In order to describe the technical content, structural features, achieved goals and effects of the present utility model in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

Please refer to FIG. 1 , the injection mold 1 of the present invention includes a first mold core 10 and a second mold core 20 .

Please refer to FIG. 2 , the first mold core 10 includes a first template 11 and a plurality of first cores 12 . The first template 11 is in the shape of a rectangular plate, and the first template 11 is provided with four upper parts 111 of the runner grooves in a square shape. The plurality of first cores 12 are embedded on the first template 11 , and the first cores 12 are distributed in two rows and four columns on the lower part 111 of the runner groove. The first template 11 is provided with two upper part of the flow channel 112 , and the upper part of the flow channel 112 is extended to the upper part of the channel groove 111 by two upper parts of the branch channel 113 .

Please refer to FIG. 3 , the second core 20 includes a second template 21 and a plurality of second cores 22 . The second template 21 is also in the shape of a rectangular plate, and the second template 21 is provided with four lower portions 211 of the runner grooves in a square shape. The plurality of second cores 22 are embedded on the second template 21 , and the second cores 22 are distributed in two rows and four rows on the lower part 211 of the runner groove. The second template 21 is provided with a main channel 23 , the end of the main channel 23 extends to both sides to form a sub-channel lower part 212 , and the sub-channel lower part 212 has two branch channel lower parts 213 extending toward the runner groove lower part 211 .

Please refer to Fig. 1 again, when the injection mold 1 is closed, the first mold core 10 and the second mold core 20 are buckled together, and the first mold core 10 and the second mold core 20 are respectively enclosed into four depths. Shallow shallow groove runners 31 and several mold cavities 32 all (or part of) are located in these runner grooves. Wherein, the upper part 11 of the runner groove and the lower part 21 of the runner groove synthesize the shallow groove runner 31, the depth of the shallow groove runner 31 is much smaller than the depth of the cavity 32, and can be formed under the injection pressure of the injection molding machine. When ensuring that the mold cavity 32 is fully filled with plastic, the shallower the depth of the shallow groove runner 31, the better. After the product is formed, the injection mold 1 is opened to take out the product, and cutting technology is required to separate the required product from the waste.

As mentioned above, the utility model injection mold 1 connects several cavities 32 through the shallow groove flow channel 31 formed between the first mold core 10 and the second mold core 20, thereby simplifying the flow channel design and making the injection molding The design and manufacture of the mold 1 are more convenient, thereby improving production efficiency.
