Description

Structure is optimized to thin iron for injection mold

Technical Field

The utility model relates to an injection mold technical field, concretely relates to injection mold optimizes structure with thin indisputable.

Background

In the field of automobile interior decoration, most of front defrosting air outlets are integrally formed. Due to the modeling requirement, the heights of the front and rear flanges of the air outlet are different, and the characteristic can bring about the result of thin iron when the mold is molded.

Referring to fig. 1 to 4, an injection mold includes an upper mold 1 and a lower mold 2, the upper mold 1 is provided with a plurality of first bumps 11 arranged at intervals, the lower mold 2 is provided with a plurality of second bumps 21 arranged at intervals, a groove 3 for inserting the first bump 11 is formed between two adjacent second bumps 21, and a cavity 10 for forming a blade 41 is formed between the first bump 11 and the groove 3. In order to make the air outlet 4 play an effective role in guiding air, the side surfaces of the blades 41 for air intake are all inclined surfaces, so that a composite parting surface as shown in fig. 4 is formed. The direction of compound die joint is oblique ascending, and the demoulding direction of mould is from up down, the direction of demoulding direction is inequality with the direction of die joint, in order to make air outlet 4 have certain intensity and form pit 42 again, the lateral surface of second lug 21 is formed with thin iron structure 5, thin iron structure 5 is similar to the die drawing face of protrusion outside, its thickness is extremely thin, because the die joint is pure inclined plane structure, at the in-process of demoulding, the thin iron structure 5 of second lug 21 is very easy to break, thereby the influence product that forms, need often revise the mould, cost of maintenance is very high.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to the not enough among the prior art, and provide an injection mold optimizes the structure with thin indisputable, adopts this structure can solve the problem of easy fracture.

The purpose of the utility model is realized through the following technical scheme: the application provides an injection mold optimizes structure with thin iron, including last mould and lower mould, it is equipped with the first lug that a plurality of intervals were arranged to go up the mould, the lower mould is equipped with the second lug that a plurality of intervals were arranged, form between two adjacent second lugs and supply first lug male recess, the lateral surface of second lug is formed with thin iron structure, the bottom surface of first lug is equipped with oblique ascending transition structure, the tank bottom of recess seted up with transition structure matched with transition face.

Wherein the transition structure is an obliquely upward plane.

Wherein, the transition surface is an upward inclined plane.

The utility model has the advantages that: the utility model provides a structure is optimized to thin iron for injection mold sets up oblique ascending transition structure and sets up the transition surface that cooperatees with transition structure at the tank bottom of recess through the bottom surface at the second lug to increased the area of contact of die joint, made the tank bottom of first lug further laminating recess, thereby made the convex thickness of thin iron structure increase, the intensity of thin iron structure increases, has solved the problem that thin iron structure cracked easily in the past.

Reference numerals: the mold comprises an upper mold 1, a first bump 11, a cavity 10, a lower mold 2, a second bump 21, a groove 3, an air outlet 4, blades 41, a pit 42, a thin iron structure 5, a transition structure 61 and a transition surface 62.

Detailed Description

The invention will be further described with reference to the following examples.

The utility model discloses an injection mold optimizes detailed implementation of structure with thin iron, injection mold in this embodiment is as shown in fig. 5, and its exploded view is similar with 1 among the prior art and fig. 2, all includes mould 1 and lower mould 2, goes up mould 1 and is equipped with the first lug 11 that a plurality of intervals were arranged, and lower mould 2 is equipped with the second lug 21 that a plurality of intervals were arranged, forms between two adjacent second lugs 21 and supplies first lug 11 male recess 3, is equipped with the die cavity that is used for shaping air outlet 4 between first lug 11 and the second lug 21. The improvement point of the present invention is shown in fig. 6, the outer side surface of the second bump 21 in this embodiment is formed with a thin iron structure 5, the bottom surface of the first bump 11 is provided with an oblique upward transition structure 61, and the bottom of the groove 3 is provided with a transition surface 62 matched with the transition structure 61.

In the present embodiment, the transition structure 61 is a plane inclined upward, it should be noted that the inclined upward direction is set obliquely upward with reference to the bottom surface of the first bump 11, the bottom surface of the first bump 11 in fig. 7 is inclined downward (fig. 6 is inclined downward, fig. 7 is a horizontal state), and the transition structure 61 is an inclined surface set obliquely upward with respect to the bottom surface of the first bump 11, which can be seen in the schematic diagram of fig. 7. Similarly, the transition surface 62 is a planar surface that is angled upward.

The structure is optimized to a thin iron for injection mold of this embodiment, sets up ascending transition structure 61 in the slant through the bottom surface at second lug 21 and at the tank bottom setting of recess 3 with transition structure 61 transition face 62 that cooperatees to increased the area of contact of die joint, made the first lug 11 further laminate the tank bottom of recess 3, thereby made the convex thickness of thin iron structure 5 increase, the intensity of thin iron structure 5 increases, has solved the easy cracked problem of thin iron structure 5 in the past.
