Description

A multi-stage linkage gear-release mechanism for a light guide strip mold for an automotive door panel ambient light

Technical Field

The invention belongs to the technical field of molds and relates to a multi-stage linkage tooth-release mechanism of a light guide strip mold for an atmosphere lamp of an automobile door panel.

Background technique

A mold is a tool used in industrial production to obtain the desired product by methods such as injection molding, blow molding, extrusion, die casting, smelting, and stamping. The mold has a specific contour or inner cavity shape; the use of a contour shape with a cutting edge can make the blank separate according to the shape of the contour line, and the use of an inner cavity shape can make the blank obtain a corresponding three-dimensional shape. It has the advantages of simple processing, high efficiency, and the ability to obtain products with complex shapes, and is widely used; the mold generally consists of two parts, a movable mold and a fixed mold, which can be separated or combined. When separated, the workpiece is taken out, and when combined, the blank is injected into the mold cavity for forming.

The light guide strip is an energy-saving light source that combines optical design and precision processing. It is an important component in the car. After the car light is refracted by the light guide strip, it forms a light band and emits it. The intensity and color of the light are changed according to the light source. It is not only beautiful and practical, but also energy-saving and environmentally friendly. The light guide strip is generally in the shape of a slender strip and has an irregular shape. For example, the light guide structure of a car ambient light light guide strip disclosed in the patent document with publication number CN205245021U has dense light guide teeth distributed on its body.

Light guide strips are usually molded by injection molding. The injection molding quality of the light guide teeth on the light guide strips is directly related to the light shape and intensity of the headlights. However, since the light guide strips are relatively slender and the light guide teeth on the light guide strips are relatively dense, the meshing force with the mold is relatively large, resulting in great difficulty in core pulling and demolding. In particular, since the shape of the light guide strips is irregular, multiple sliders and cores are often required to form a molding cavity. The presence of light guide teeth limits the design of the slider's core pulling direction. The corresponding slider needs to be pulled out along the protruding direction of the light guide teeth. In other words, the pulling direction of the light guide tooth slider is bound to be different from the direction of other sliders. In the prior art, Different sliders and cores have different core pulling directions, so multiple guide pins or ejector pins are required to drive the core pulling operations from different directions, and the core pulling actions in different directions need to be completed in steps. This not only makes the structure of the existing mold core pulling mechanism very complicated, but also leads to low core pulling efficiency of the existing mold.

Summary of the invention

The purpose of the present invention is to address the above-mentioned problems in the existing technology and propose a multi-stage linkage tooth-removing mechanism for the automobile door panel atmosphere light light guide strip mold. The technical problem to be solved by the present invention is how to improve the core-pulling efficiency of the light guide strip while simplifying the mold structure.

The object of the present invention can be achieved through the following technical solutions: a multi-stage linkage de-toothing mechanism of a mold for a light guide strip of an atmosphere light of an automobile door panel, the mold comprising a movable mold, a fixed mold and an inclined guide column fixedly connected to the movable mold, characterized in that the multi-stage linkage de-toothing mechanism comprises a slider 1 connected to the fixed mold in a longitudinal sliding manner, a slider 2 is arranged above the slider 1, the slider 2 is connected to the slider 1 in a longitudinal sliding manner, the slider 2 has an inclined guide rail arranged along the longitudinal direction and inclined downward, a slider 3 is arranged above the slider 2, and the slider 3 has a forming tooth portion for forming light guide teeth and protruding vertically upward The bottom of the slider three is slidably connected to the inclined guide rail, and the side of the slider three is slidably connected to the slider one in the vertical direction. The slider one is provided with an inclined hole one which is arranged along the longitudinal direction and has a strip-shaped cross section, and the slider two is provided with an inclined hole two which is arranged along the longitudinal direction and has an elliptical cross section. The longitudinal length of the inclined hole two is smaller than the longitudinal length of the inclined hole one, and the inclined guide column can be inserted into the inclined hole two and the inclined hole one in sequence; when the slider three performs the tooth stripping and core pulling action, the inclined guide column drives the slider two to move alone; when the mold is opened after the slider three completes the tooth stripping and core pulling action, the inclined guide column drives the slider one and the slider two to move synchronously.

Different from the prior art, the present invention makes innovative improvements to the connection between the sliders used to form the light guide strip, so that the sliders can be driven to perform core pulling actions by using only one component, the inclined guide column, including the core pulling action of the slider used to form the light guide teeth. Specifically, the multi-stage linkage tooth-release mechanism includes slider 1, slider 2, and slider 3, all of which are used to cooperate with the core of the mold to form the light guide strip, wherein slider 3 has a forming tooth portion for forming the light guide tooth and protruding vertically upward, by sliding slider 1 on the fixed mold along the longitudinal direction, sliding slider 2 on the top of slider 1 along the longitudinal direction, and designing an inclined guide rail on slider 2 that is arranged along the longitudinal direction and tilted downward, and slidingly connecting the bottom of slider 3 with the inclined guide rail, and slidingly connecting the side of slider 3 with slider 1 along the vertical direction, after the above linkage design, when slider 1 is stationary When the slider two slides longitudinally relative to the slider one, the slider three will move vertically. Since the formed tooth portion on the slider three is also vertically raised, the slider three can complete the core pulling operation of removing the undercut under the drive of the slider two. On the basis of the above-mentioned linkage design of each slider, an inclined hole one for cooperating with the inclined guide column is provided on the slider one, and an inclined hole two for cooperating with the inclined guide column is provided on the slider two, and the cross section of the inclined hole two is designed to be elliptical, and the cross section of the inclined hole one is designed to be strip-shaped. Both are arranged longitudinally and the longitudinal length of the inclined hole two is less than the longitudinal length of the inclined hole one. After such a design, when the inclined guide column When the columns are inserted into the inclined holes 2 and 1 in sequence, two actions can be realized. First, when the slider 3 performs the stripping and core pulling action, that is, the inclined guide column squeezes the inclined hole 2 alone, then it is to move the slider 2 alone. At this time, the inclined guide column moves in the inclined hole 1 but does not contact the inclined hole 1. The inclined hole 1 is similar to the role of the yield hole. In this way, the inclined guide column drives the slider 2 to move, so that the slider 3 will also move under the drive of the slider 2, thereby realizing the upward stripping and core pulling action of the slider 3; second, when the slider 3 completes the stripping and core pulling action, there is no obstruction from the inverted teeth, and the mold can be opened at this time. As the movable mold moves, the inclined guide pin will contact the hole walls of the inclined hole 1 and the inclined hole 2 at the same time. At this time, the inclined guide pin can simultaneously push the slider 1 and the slider 2 to move synchronously. At this time, the slider 3 will also move outward with the slider 1 and the slider 2, thereby realizing the overall demoulding action of the slider 1, the slider 2, and the slider 3; that is to say, the inclined guide pin can drive the slider 1 to complete the core pulling action, and can also drive the slider 2 to complete the core pulling action. After the inclined guide pin drives the slider 2, the slider 3 can also complete the core pulling action under the drive of the slider 2, and the core pulling direction of the slider 3 with the formed tooth portion is consistent with that of the slider 1. The core pulling directions of block one and slider two are completely different, but the present invention can realize the core pulling actions of the three sliders in different directions by using the above-designed inclined guide column as one component, and the movements of each slider are closely linked and connected without wasting time. This not only reduces the design of driving components such as guide columns or ejector rods, simplifies the mold, but also greatly improves the efficiency of the core pulling operation.

The specific working process of the multi-stage linkage tooth-removing mechanism is as follows: when the mold is in the mold-closing state, the inclined guide pin is inserted into the inclined hole 2 and the inclined hole 1. At this time, the inclined guide pin is pressed on the inner end hole wall of the inclined hole 1, and the outer end hole wall of the inclined hole 1 is separated from the inclined guide pin by a distance; when the mold performs the tooth-removing and core-pulling action of the slider 3, at this time, the inclined guide pin slowly moves upward with the movable mold, and then it will squeeze the hole wall of the inclined hole 2 to push the slider 2 relative to the slider 1 in the direction away from the core to perform the first section of the core-pulling action, and the slider 3 will move synchronously under the drive of the slider 2. After the core pulling action of slider 3 is completed, the mold officially enters the mold opening action, and the inclined guide column continues to move upward until it contacts the outer end hole wall of inclined hole 1. At this time, the inclined guide column can simultaneously move slider 1 and slider 2 away from the core. At this time, slider 1 performs the core pulling action, and slider 2 performs the second stage of the core pulling action. Since slider 3 is connected to slider 1 along the vertical sliding, the two are relatively immobile in the longitudinal direction, that is, slider 3 will also move outward with slider 1 and slider 2 at this time. As the inclined guide rail continues to move upward, the three sliders move outward together until the demoulding action is finally completed.
