Embodiment 1

[0039] Such as Figure 4 As shown, a storage box for automotive interior parts, the storage box includes a box body 1, which has an accommodating cavity 1-1 with an upward opening, and outwardly protruding ears are arranged on the outer walls of both sides of the box body 1. The straps 2 and the ear straps 2 are elongated. There are two ear straps 2 on the outer walls of the box body 1 and they are parallel to each other.

[0040] Because, the material of box body 1 is ABS plastic, and ABS plastic has good surface hardness and higher impact strength, and ABS plastic can't be applied forcibly pushed out because of the reason of surface hardness, otherwise box body will be damaged when demoulding, so In order to facilitate the demoulding of the box body, the specific structure of the ear strap is designed as follows:

[0041] The cross-section of the ear strap 2 is arc-shaped, and when the push rod 5 pushes it out from the male mold core 3, the ear strap 2 with a circular-arc c...

Embodiment 2

[0044] Such as Figure 9As shown, the difference between Embodiment 2 and Embodiment 1 is that: the side of the ear strap 2 close to the bottom of the box body 1 is a slope 202, the side of the ear strap 2 close to the opening of the box body 1 is an arc surface 201, and the slope 202 is in line with the circle. The arc surface 201 is tangent to realize that the slope of the side of the ear strap 2 close to the bottom of the box body 1 is small, and the slope of the side of the ear strap 2 close to the opening of the box body 1 is large, so that when the mold is opened, the side of the ear strap 2 with a large slope is more Hook the male mold core 3 well; when demolding, the side with the smaller slope of the ear strap 2 is conducive to the elastic deformation of the side wall where the ear strap 2 is located on the box body 1 toward the direction of the accommodating cavity 1-1.

Embodiment 3

[0046] Such as Figure 5-7 As shown, a mold for producing the above-mentioned storage box for automotive interior parts includes a male mold core 3, a female mold core 4 and a push rod 5, and the female mold core 4 has an accommodating cavity 1 with the box body 1 -1 matching protrusion 4-1, the male mold core 3 has a groove 3-1, when the male mold core 3 and the female mold core 4 are combined together, the protrusion 4-1 and the groove 3- 1 to form a cavity matching the storage box of the automotive interior trim, and the push rod 5 passes through the male die core 3 and the groove 3-1 thereon.

[0047] The molding process of the automotive interior parts storage box using the above-mentioned mold is as follows:

[0048] The molten plastic is injected into the cavity between the male mold core 3 and the female mold core 4 at a certain injection pressure, and it is filled, and a certain pressure is maintained to compact the plastic. Under the action of the injection molding ...

Abstract

The invention relates to the technical field of car interior trim part storage boxes, in particular to a car interior trim part storage box and a mould thereof. The storage box comprises a box body, a containing cavity with an upward opening is formed in the box body, and lug strips bulge outwards are arranged on the outer walls of the two sides of the box body correspondingly; the mould used for manufacturing the car interior trim part storage box comprises a core insert, a cavity insert and pushing rods, the cavity insert is provided with bulges matched with the containing cavity of the box body, grooves are formed in the core inserts, and mold cavities matched with the car interior trim part storage box are formed between the bulges and the grooves when the core inserts and the cavity inserts are put together; and the pushing rods penetrate through the core inserts and the grooves on the core inserts, through changing contacting positions of the end surfaces of the pushing rods and the surface of the box body, structures of the end surface of the pushing rods are reflected on the bottom surface, free of appearance quality requirement, of the outside of the box body, so that a problem of moulages on the bottom surface of the containing cavity of the box body is solved, and the requirement for the appearance quality of the car interior trim part storage box is met.

Description

technical field [0001] The invention relates to the technical field of storage boxes for automotive interior parts, in particular to a storage box for automotive interior parts and a mold thereof. Background technique [0002] With the rapid development of my country's automobile industry, the development of automotive interior parts has also advanced by leaps and bounds, becoming the fastest growing item in auto parts. Now auto consumers are paying more and more attention to car interiors. High-quality interior parts are beautiful and comfortable, giving people Also enjoy. The interior of the car is mainly composed of plastic parts7. The quality of the injection mold is an important factor affecting the interior of the car. Therefore, it is of great significance to study the mold of the interior of the car. [0003] Existing automotive interior parts savings box is usually such as figure 1 As shown, the plastic part 7 has a length of 115mm, a width of 50mm, a maximum heigh...
