Description

Technical Field

[0001] The utility model belongs to the technical field of headlamp molds and relates to an injection mold for a motorcycle headlamp cover. Background Technique

[0002] As the main lighting device of a motorcycle, the front headlamp of a motorcycle plays a crucial role during the driving of the vehicle, especially during night driving. Existing motorcycle front headlamps usually include a lamp cover, a lamp holder, and a reflector bowl. These components are all processed through injection molds during processing.

[0003] Currently, in the production and manufacturing of the upper mold base of a headlamp, the template structure of the headlamp mask is directly fixed to the mold base through threads. Especially for the upper template structure, only one set is fixed. When replacement is needed, it can only be disassembled and another set of upper template structures needs to be reinstalled, which causes the problem of slow replacement and installation efficiency of the upper template and affects subsequent processing. Summary of the Invention

[0004] The purpose of the utility model is to provide an injection mold for a motorcycle headlamp cover to solve the problems raised in the above background technique.

[0005] The purpose of the utility model can be achieved by the following technical solutions: An injection mold for a motorcycle headlamp cover includes a mold base, a pressing plate, a locking rod, side plates, and telescopic support rods. A rotating rod is movably installed on one side inside the mold base. One end of the rotating rod is connected to a rotating frame. Both ends of the rotating frame are connected to side arm plates. Two limiting chutes are provided on the inner wall surface of the side arm plates. An upper template and a lower template are installed between the two side arm plates through the limiting chutes. Inner sliders are connected to both sides of the upper template and the lower template. The inner sliders slide inside the limiting chutes. A pressing plate is movably arranged at the top position of the mold base. Plug plates are connected to both sides at the bottom end of the pressing plate.

[0006] In the above injection mold for a motorcycle headlamp cover, four groups of telescopic support rods are provided at the top edge side of the mold base, and the top ends of the telescopic support rods are connected to the bottom edge side of the pressing plate.

[0007] In the above injection mold for a motorcycle headlamp cover, a lifting cylinder is provided at the top edge side of the mold base, and the output end of the lifting cylinder is connected to the bottom edge side of the pressing plate.

[0008] In the above injection mold for a motorcycle headlamp cover, an upper insertion hole is provided at the top end of the side arm plate. An inner limiting hole is provided inside the inner slider. A positioning rod one is connected to the bottom end of the pressing plate. The bottom end of the positioning rod one passes through the upper insertion hole and is placed in the inner limiting hole.

[0009] In the above-mentioned injection mold for a motorcycle headlight lamp cover, support slots are provided at both ends of the upper template and both ends of the lower template, and the bottom end of the insertion plate is inserted into the interior of the support slots.

[0010] In the above-mentioned injection mold for a motorcycle headlight lamp cover, positioning holes are provided at the ends of the side arm plates, two positioning rods II are connected to the inner side of the side plates, and the positioning rods II are inserted into the interior of the positioning holes. A locking rod is threadedly connected to the side of the side plate.

[0011] Compared with the prior art, the advantages of the injection mold for a motorcycle headlight lamp cover of the present utility model are as follows: This application improves the existing injection mold frame. A rotatable rotating frame and two side arm plates are provided inside the traditional mold frame. An upper template and a lower template are symmetrically installed up and down between the two side arm plates. By rotating the rotating frame, the upper template and the lower template can be switched for use. After adjusting the position of the template, the side plate can be pushed inward, so that the positioning rod II inside the side plate is inserted into the side arm plate to fix the side arm plate. Then, under the push of the lifting cylinder, the pressing plate can move towards the mold frame. The bottom end of the positioning rod I passes through the upper insertion hole and is placed inside the inner limiting hole to limit the inner slider and the sides of the two templates. At the same time, the insertion plate can be inserted into the support slot to further support the upper template and the lower template. In this way, when the upper template and the lower template are used for injection molding, the stability is better. BRIEF DESCRIPTION OF THE DRAWINGS
