Title:
METHOD FOR MANUFACTURING INTEGRATED LAMP CUP, AND STRUCTURE FOR FIT BETWEEN INTEGRATED LAMP CUP AND MOLD
Document Type and Number:
WIPO Patent Application WO/2019/170101
Kind Code:
A1
Abstract:
A method for manufacturing an integrated lamp cup, and a structure for fit between an integrated lamp cup and a mold. The method for manufacturing an integrated lamp cup comprises: stamping a conductive blank into a lamp cup body (5) having a base (501) and a cup (502); sleeving a rear mold core (1) of a mold with the lamp cup body (5) so that the cup is attached onto the rear mold core (1) to form an inner sealing position (6, 7); and sleeving the periphery of the cup (502) with a front mold (2) of the mold, and making the front mold (2) in clearance fit with the light cup body (5), so that a slider mechanism (3) of the mold abuts against the front mold (2) and is attached to the base (501), a flow channel mechanism (4) of the mold is attached to the top end of the base (501), and an outer sealing position (8, 9) is formed between the slider mechanism (3) as well as the flow channel mechanism (4) and the base (501). The base, as a conductive portion, is exposed, and the outer sealing position can prevent an insulating material from staying on the conductive portion, thereby improving the appearance and quality of the base, ensuring good contact between the base and an external circuit, and ensuring smooth circuit of the base. The inner sealing position prevents the insulating material from entering the cup, and can effectively control the effective contact between the cup and other conductive components, thereby ensuring smooth internal circuit of the cup.
