Positioning mechanism for iron parts on left and right sides of automobile sunroof products

Abstract

The invention relates to a positioning mechanism for iron parts on left and right sides of automobile sunroof products. The positioning mechanism comprises an outer positioning assembly and an inner positioning assembly, wherein the outer positioning assembly comprises a bottom plate and a driving air cylinder, a diagonal pressing block, a guiding rail and an ejection spring, which are fixed on the bottom plate; the guiding rail is movably connected with a side pulling slider; one end of the ejection spring is connected with the side, close to an iron part, of the side pulling slider; the other end of the ejection spring abuts the iron part; the inner positioning assembly comprises a driving gas cylinder, an ejection member and a connecting rod member, which are fixed on a lower mold; a plurality of positioning pins are movably penetrated in the ejection member; the connecting rod member is used for transferring the pushing force of the driving gas cylinder to the ejection member; andone end of the positioning pin is pushed into a positioning hole or the positioning pin in the positioning hole is pulled back to ejection member through the ejection member. Compared with the prior art, the positioning mechanism saves the time of secondary ejection after ejecting and opening a clamping block, reduces the flashing phenomenon during the injection molding, and improves the product yield.

Description

technical field [0001] The invention relates to the field of injection molds, in particular to a positioning mechanism for iron parts on the left and right sides of automobile sunroof products. Background technique [0002] Automobile sunroof products are produced by injection molding the iron parts on both sides and the glass in the middle. The specific production process requires precise positioning of the iron parts to ensure the relative angle and position of the iron parts and the glass in the product. Existing The positioning mechanism of the iron parts on the left and right sides of the car sunroof product is the clamping block sealing strip. When opening the mold to pick up the parts, the clamping sealing strip needs to be ejected first, and then the iron parts are ejected. This process makes the position of the iron parts accurate. The lower the degree, especially the vertical position degree is more prone to deviation. The program of clamping block structure is co...

[0002] Automobile sunroof products are produced by injection molding the iron parts on both sides and the glass in the middle. The specific production process requires precise positioning of the iron parts to ensure the relative angle and position of the iron parts and the glass in the product. Existing The positioning mechanism of the iron parts on the left and right sides of the car sunroof product is the clamping block sealing strip. When opening the mold to pick up the parts, the clamping sealing strip needs to be ejected first, and then the iron parts are ejected. This process makes the position of the iron parts accurate. The degree is low, especially the vertical position degree is more prone to deviation

The program of clamping block structure is complicated. After the clamping block is ejected, it is opened and then ejected again. The overall production process is lengthened and the mold opening time is wasted.

On the other hand, the clamping block structure is easy to wear during the production process, resulting in flashes and flashes in the product. However, it is difficult to clean the flashes during the specific processing and will affect the overall production process. Failure to deal with the flashes will lead to Product appearance is bad
