Abstract
Description
Technical Field
[0001] This utility model belongs to the field of injection mold technology, and more specifically, it relates to the ejection mechanism of the fixed mold insert of automotive lamp injection mold. Background Technology
[0002] When the injection-molded car light is ejected from the fixed mold insert of the mold, the ejector rod and the ejector plate move to smoothly eject the injection-molded car light from the fixed mold insert. This method can provide a large ejection area and uniform ejection force, which is beneficial to protect the appearance and quality of the injection-molded car light. After the car light is ejected, the restoring force of the return spring will pull the ejector plate back to its original position.
[0003] Based on the above, the thin-walled part of the molded headlight is prone to sticking to the top plate. Due to the low strength of the thin-walled part of the headlight, it is easily deformed by the ejection force during ejection, which not only affects the injection molding effect of the headlight, but also affects the ejection efficiency of the headlight, and thus affects the performance of the ejection mechanism. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a fixed mold insert ejection mechanism for automotive lamp injection molds, which solves the problem that the thin-walled part of the molded automotive lamp is easy to stick to the top plate. Because the thin-walled part of the automotive lamp has low strength, it is easily deformed by the ejection force during ejection, which not only affects the injection molding effect of the automotive lamp, but also affects the ejection efficiency of the automotive lamp, and thus affects the use effect of the ejection mechanism.
[0005] The purpose and function of the fixed mold insert ejection mechanism of this utility model's automotive lamp injection mold are achieved by the following specific technical means:
[0006] The fixed mold insert ejection mechanism of the automotive headlight injection mold includes an ejector electric push rod, a positioning mounting plate, guide ejector rods, a first headlight push plate, a limiting structure, a material ejection structure, a guide connecting plate, a fourth extrusion wedge, and a second headlight push plate. The positioning mounting plate is fixedly connected to the upper part of the piston rod of the ejector electric push rod. Four guide ejector rods are provided, and the four guide ejector rods are evenly distributed and threadedly connected to the upper part of the positioning mounting plate. The first headlight push plate is bolted to the upper part of the four guide ejector rods. The limiting structure is located on the upper part of the positioning mounting plate. The guide connecting plate is slidably connected to the middle part of the first headlight push plate.

[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] This invention applies a small pushing force to the headlight by reciprocating the movement of the second headlight pusher plate, which also causes the headlight to vibrate, gradually detaching it from the first headlight pusher plate. This effectively prevents the headlight from deforming due to excessive ejection force, ensuring the injection molding effect and improving the production quality of the headlight. It also allows the headlight to separate from the first headlight pusher plate more quickly, improving the effectiveness of the ejection mechanism, increasing the ejection efficiency of the headlight, saving a significant amount of time, and effectively improving the production efficiency of the headlight. Furthermore, it can shake off any residue remaining on the ejection mechanism, effectively avoiding the inconvenience of manually cleaning the ejection mechanism. Attached Figure Description

[0027] The specific usage and function of this embodiment: After the headlight is injection molded, the ejector electric push rod 1 is activated to push the piston rod to slide along the position limiting plate 202, the guide ejector rod 3 and the first headlight push plate 4, thereby causing the headlight to disengage from the fixed mold insert. The damping elastic element 201 can buffer the movement of the first headlight push plate 4.
[0028] Example 2:
[0029] As attached Figure 1 To be continued Figure 6 As shown:
[0030] Based on Embodiment 1, a pushing structure is also included; the pushing structure is disposed above the positioning mounting plate 2.
[0031] The material pushing structure includes a first extrusion inclined block 301 and a first reset elastic element 302; four first extrusion inclined blocks 301 are provided, and the four first extrusion inclined blocks 301 are slidably connected to the upper part of the four guide ejector rods 3 respectively; four first reset elastic elements 302 are provided, and the four first extrusion inclined blocks 301 are elastically connected to the four guide ejector rods 3 through the four first reset elastic elements 302.
