Description

Technical Field

[0001] The utility model relates to an injection mold for an automobile storage box bucket. Background Art

[0002] Storage boxes in cars are usually located in the instrument panel center console, door inner panels, rear seats, seat bottoms, outer edges, front and rear storage boxes, and the roof. Various small items such as sundries and personal items can be placed as needed, thereby providing storage space for drivers and passengers. Storage boxes on the market are almost all plastic parts, so they are manufactured by injection molding, and the injection molding process must use matching injection molds.

[0003] Since multiple buckles need to be formed on the edge of the opening of the storage box bucket, in order to form the above-mentioned buckles, the existing storage box bucket injection mold can only set multiple auxiliary molding blocks circumferentially inside the molding cavity of the fixed module, and at the same time set a corresponding number of cylinders on the outer wall of the fixed module to drive the auxiliary molding blocks to move individually. Although this can achieve the desired effect, the production cost of the mold is relatively high because multiple cylinders are used; and the processing process of the mold is relatively complicated and time-consuming, which needs further improvement.

A second vertical partition groove 1714 is provided between the upper and lower outer walls of the end of the third protrusion 1712 to intersect and communicate with each second transverse partition groove 1713.

[0060] Working principle:

[0061] The fixed module 3 is fixed and the movable module 1 is driven to move backward until the rear side of the movable module 1 and the front side of the fixed module 3 are spliced ​​together, and then the mold base 21 on the movable mold core 2 fixed behind the movable module 1 is inserted into the mold cavity 31 on the fixed module 3, and the molten material is passed through the runner set in the movable module 1 into the space between the mold base 21 and the mold cavity 31. After cooling, the storage box bucket can be formed. The above principle is the existing technology.

[0062] When the movable module 1 moves, the push plate 4 will move synchronously with the movable module 1, but will always maintain a certain distance from the movable module 1; after the movable module 1 and the fixed module 3 are assembled with each other and before the molten material is injected, it is necessary to drive the push plate 4 to move toward the movable mold core 2, thereby driving the first traction bar 6, each second traction bar 7, each third traction bar 10, each fourth traction bar 11 and each fifth traction bar 14 to pass through and move backward, thereby respectively driving the first passive bar 5, each third passive bar 9 and each fifth passive bar 13 to move upward, so that the end of the concave cavity forming block 51 on the first passive bar 5 passes upward through the first cavity hole 23 and extends into the interior of the mold cavity 31, and at the same time, the end of the second forming protrusion 91 on each third passive bar 9 passes upward through the corresponding A third cavity 212 extends into the interior of a corresponding positioning opening groove 24, and the end of the fourth molding protrusion 131 on each fifth passive strip 13 passes upward through a corresponding fifth cavity 214 and extends into a corresponding second positioning notch cavity 25; and each second passive strip 8 and each fourth passive strip 12 move downward, so that the end of the first molding protrusion 81 on each second passive strip 8 passes downward through a corresponding second cavity 211 and extends into the interior of a corresponding positioning opening groove 24, and at the same time, the end of the third molding protrusion 121 on each fourth passive strip 12 passes downward through a corresponding fourth cavity 213 and extends into a corresponding second positioning notch cavity 25, and then the molten material can be injected.

[0063] When the movable module 1 moves toward the fixed module 3, the insertion strip 152 in the first inclined lift mechanism 15 will move synchronously with the movable module 1, thereby forcing the first slider 151 to move downward until the first core block 1511 is inserted into the first positioning notch cavity 210, and at this time, the end faces of the two first protrusions 1512 will respectively fit with the end faces of the two second protrusions 2101; the first inclined rods 162 in the two second inclined lift mechanisms 16 will also move synchronously with the movable module 1, thereby forcing the two second sliders 161 to move toward the mold cavity 31, until the two second core blocks 1611 are respectively inserted into the two positioning opening grooves 24; the second inclined rods 172 in the two third inclined lift mechanisms 17 will also move synchronously with the movable module 1, thereby forcing each third slider 171 to move toward the mold cavity 31, until the two third core blocks 1711 are respectively inserted into the two second positioning notch cavities 25.

[0064] When the injected molten material cools down, the first core block 1511 and the first positioning notch cavity 21 will form a main plug-in plate at the upper edge of the storage box opening, and the two second core blocks 1611 and the two third core blocks 1711 will respectively form two auxiliary plug-ins on the left and right sides of the storage box opening; the end of the concave cavity forming block 51, the end of each second forming protrusion 91, the end of each fourth forming protrusion 131, the end of each first forming protrusion 81, and the end of each third forming protrusion 121 will respectively form depressions on the inner walls of the main plug-in plate and the corresponding auxiliary plug-ins.

[0065] During demolding, first drive the push plate 4 to move away from the movable module 1, and then drive the end of the cavity forming block 51 to retreat to the inside of the first guide groove 22 by the same logic, and at the same time drive the end of each first forming protrusion 81 and the end of each second forming protrusion 91 to retreat to the inside of a corresponding second guide groove 26 and third guide groove 27 respectively, and at the same time drive the end of each fourth forming protrusion 131 and each third forming protrusion 121 to retreat to the inside of a corresponding fourth guide groove 28 and fifth guide groove 29 respectively; then drive the movable module 1 to move away from the fixed module 3 until the mold base 21 completely leaves the mold cavity 31, and finally remove the formed storage box bucket with the help of the ejection mechanism provided on the fixed module 3.

[0066] The utility model can form multiple clips on the edge of the opening of the storage box bucket with the help of a concave cavity forming component, two second concave cavity forming components, two third concave cavity forming components, two fourth concave cavity forming components and two fifth concave cavity forming components without adding a cylinder, thereby greatly reducing the production cost of the mold; in addition, since the concave cavity forming component, two second concave cavity forming components, two third concave cavity forming components, two fourth concave cavity forming components and two fifth concave cavity forming components are all arranged on the movable module 1, and only holes need to be opened on the movable module 1, the concave cavity forming component, two second concave cavity forming components, two third concave cavity forming components, two fourth concave cavity forming components and two fifth concave cavity forming components can be processed separately, thereby greatly simplifying the processing process of the mold and effectively shortening the processing time.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
