Description

Technical Field

[0001] This utility model belongs to the field of mold demolding technology, and relates to a multi-angle combined inclined top demolding mechanism for electric vehicle headlight decorative ring molds. Background Technology

[0002] Plastic products, such as headlight decorative rings for electric vehicles, are produced using injection molds. Based on the product's shape and structure, the headlight decorative ring is a circular plastic part with an undercut. There are also four symmetrical clips on the inner wall of the headlight decorative ring. Therefore, when designing its processing mold, in addition to designing its molding structure, it is also necessary to design a demolding structure for the undercut and clips.

[0003] Existing technologies typically employ a slanted ejector for demolding. However, most slanted ejector demolding methods only use a single ejector rod and ejector block, as shown in the existing patent number CN202420394985.X. For the decorative ring of an electric vehicle headlight, which is a circular shape, the slanted ejector can only lift the circular part during demolding, easily causing damage and cracking of the decorative ring during the demolding process. Therefore, we have designed a multi-angle combined slanted ejector demolding mechanism for electric vehicle headlight decorative ring molds. Summary of the Invention

[0004] The purpose of this utility model is to provide a multi-angle combined inclined ejector mechanism for electric vehicle headlight decorative ring molds, so as to solve the problems mentioned in the background art.

The inclined ejector demolding component includes several inclined ejector forming blocks I, several inclined ejector forming blocks II, several inclined ejector rods I, and several inclined ejector rods II; the several inclined ejector forming blocks I and several inclined ejector forming blocks II are arranged sequentially at intervals and spliced ​​into a ring structure; each inclined ejector forming block I is integrally formed with each inclined ejector rod I, and each inclined ejector forming block II is integrally formed with each inclined ejector rod II.

[0006] In the aforementioned multi-angle combined inclined ejector demolding mechanism for the electric vehicle headlight decorative ring mold, the outer ring of the decorative ring forming mold core is provided with several forming recess positions one and several forming recess positions two, which are arranged alternately. This arrangement is intended to allow several inclined ejector forming blocks one and several inclined ejector forming blocks two to be inserted sequentially into their corresponding forming recess positions one and two.

[0007] In the above-mentioned multi-angle combined inclined ejector demolding mechanism for electric vehicle headlight decorative ring mold, a transition connecting block is provided at the connection between each inclined ejector forming block 1 and each inclined ejector rod 1, and each transition connecting block corresponds to each forming recess position 1; a transition limiting block is provided at the connection between each inclined ejector forming block 2 and each inclined ejector rod 2, and each transition limiting block corresponds to each forming recess position 2.

[0008] Wherein: each of the transition connecting blocks has a contact molding surface on both sides, and the contact molding surface makes contact with the side wall of the molding notch position one; each of the transition limiting blocks has a molding surface on both sides, and the molding surface makes contact with the side wall of the molding notch position two.

[0009] The purpose of this design is to ensure that the inclined top forming block one and the inclined top forming block two are connected to the outer ring of the decorative ring forming mold core, which has good connection firmness and contact stability.

[0010] In the aforementioned multi-angle combined inclined ejector demolding mechanism for the electric vehicle headlight decorative ring mold, the bottom end of the lower injection mold body of the decorative ring is provided with several inclined rod guide channels one and several inclined rod guide channels two. These inclined rod guide channels one and two are arranged at intervals and correspond sequentially to several inclined ejector pins one and two. This arrangement ensures that the inclined ejector pins one and two can be sequentially inserted into their respective inclined rod guide channels one and two.

[0011] Compared with the prior art, the advantages of the multi-angle combined inclined ejector demolding mechanism of the electric vehicle headlight decorative ring mold of this utility model are as follows: by setting the inclined ejector demolding component, several inclined ejector forming blocks one and several inclined ejector forming blocks two are arranged in sequence at intervals and spliced ​​into a ring structure. During the demolding process, multi-angle combined demolding can be achieved, which makes the demolding efficiency of the formed decorative ring better, the separation from the mold more thorough, and the demolding quality is guaranteed.
