Vehicle-mounted fisheye lens injection mold jig

Abstract

The invention discloses a vehicle-mounted fisheye lens injection mold jig. The vehicle-mounted fisheye lens injection mold jig comprises a fixed mold base plate, a mold cavity plate, a supporting plate and a movable mold base plate, which are horizontally arranged in sequence from top to bottom, wherein a feeding opening, which is communicated with an inner cavity of a fixed mold cavity plate, isformed in the fixed mold base plate; the supporting plate is fixedly connected with the movable mold base plate through a plurality of bracing plates which are vertically arranged; the mold cavity plate comprises a fixed mold cavity plate which is fixedly connected with the fixed mold base plate and a movable mold cavity plate which is fixedly arranged on the supporting plate; a first guide columnand a resetting rod are vertically arranged between the supporting plate and the movable mold base plate; a horizontal ejection rod fixing plate is arranged on the first guide column and the resetting rod in a sliding manner; a resetting spring with two ends which abut against the supporting plate and ejection rods respectively sleeves the resetting rod; the plurality of ejection rods are vertically and fixedly arranged at the top part of the ejection rod fixing plate; the ejection rods are vertically arranged and penetrate through the supporting plate and the movable mold cavity plate. The vehicle-mounted fisheye lens injection mold jig disclosed by the invention has a uniform ejection force and prevents a product from being scrapped due to uneven stress, and the yield of the product isimproved.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to an injection mold fixture for a vehicle-mounted fisheye lens. Background technique [0002] Vehicle surveillance has very strict requirements for the selection of cameras, because the technology of the lens will directly determine the quality of the image and video. If the pixels of the collected data are not high, no matter how powerful the subsequent processing function is, it will not be able to obtain high-quality images. The quality of the lens depends on whether the material, design and production mold of the lens are selected reasonably. The existing mold injection molding process is to heat the plastic to a molten state, fill it in the cavity of the mold, solidify after cooling to form a product, and then perform secondary processing such as manual mold removal and glue removal. [0003] However, the traditional vehicle-mounted lens injection mold cannot be appli...

AI Technical Summary

Problems solved by technology

[0003] However, traditional automotive lens injection molds cannot be applied to plastic aspheric surfaces, and manual secondary operations are required. The production efficiency is low, and the design of the ejection mechanism is simple, which makes the ejection force uneven and prone to scratches, which makes the product scrapped, which increases the cost and reduces the cost. The qualified rate of the product is reduced. In addition, most of the cooling process adopts natural cooling, which requires a long cooling time and the injection molding efficiency is not high.
