Abstract
Description
Technical Field
[0001] The utility model relates to the field of moulds, in particular to an automobile upper decorative plate mould. Background Art
[0002] The upper trim panel of a car is one of the main trim panels of a car and is usually produced by injection molding.
[0003] like Figure 3 The figure shows a three-dimensional diagram of the automobile upper trim panel 6. Since there are three large notches 61 on it, the current mold for producing automobile upper trim panels has great deficiencies: during the casting process, as the product cools and forms, it will shrink in the direction of the notches, causing deformation of the product, affecting the dimensional accuracy and installation position accuracy of the product. Not only does it require additional shaping processes at a later stage, which increases production costs, but the overall product yield is poor, resulting in losses. Utility Model Content
[0004] Purpose of the utility model: The purpose of the utility model is to provide an automobile upper trim panel mold, which solves the problems existing in the production of automobile upper trim panel molds.
[0005] Technical solution: The utility model provides a mold for an automobile upper trim panel, including a pouring structure, a molding structure, a tightening structure, an ejection structure, and a guide structure; the molding structure includes an upper mold structure and a lower mold structure arranged in a vertical direction; the tightening structure includes a tightening component arranged in the upper mold structure, and a support frame arranged in the lower mold structure. After the mold is closed and poured, as the automobile upper trim panel parts are cooled and formed, the tightening structure is located in the upper mold structure. The tightening component presses the support frame located in the lower mold structure, so that the automobile upper trim panel parts will not shrink into the notch during the cooling process, thereby effectively avoiding the deformation of the parts, etc., thereby greatly improving the molding quality of the automobile upper trim panel.
[0006] Furthermore, the jacking assembly includes a cylinder, an ejector pin, and a limiting sleeve, wherein one end of the ejector pin is connected to the cylinder, and the other end is arranged in the limiting sleeve. Under the action of the cylinder, the ejector pin reciprocates vertically along the limiting sleeve, thereby playing the role of pressing and loosening the support frame, and its operation is simple and convenient.
[0007] Furthermore, the ejection structure is provided with an oblique ejector pin. The upper trim panel of the automobile is completely demoulded under the action of the ejection structure, and the oblique ejector pin arrangement effectively avoids the ejector pin being stuck in the mold and causing deformation.
[0008] Furthermore, the upper mold structure includes an upper fixed plate, an upper mold plate, and an upper mold core. The upper mold plate is arranged on the upper fixed plate, and the upper mold core is arranged in the upper mold plate.
[0009] Furthermore, the lower mold structure includes a lower fixed plate, a mold foot, a lower mold plate, and a lower mold core. The lower mold plate is connected to the lower fixed plate through the mold foot, and the lower mold core is arranged in the lower mold plate.
[0010] Furthermore, the pouring structure includes a positioning ring, a gate sleeve, a main channel, and a plurality of branch channels connected to the main channel. The arrangement of multiple branch channels not only improves the injection molding efficiency, but also makes the internal uniformity of the poured automobile upper trim better, greatly improving the product quality.
[0011] Furthermore, the guide structure has four groups, including guide pillars and guide sleeves. One end of the guide pillar is arranged on the upper mold structure, and the other end is arranged in the guide sleeve located in the lower mold structure.
[0012] It can be seen from the above technical scheme that the utility model has the following beneficial effects: 1) A clamping structure is provided, and during the cooling and molding process, the clamping assembly located in the upper mold structure presses the support frame located in the lower mold structure, thereby supporting and shaping the notches of the automobile upper trim parts, thereby effectively avoiding deformation of parts, etc., greatly improving the yield rate of the automobile upper trim and reducing production costs; 2) The structure is simple, easy to operate, and has wide applicability.
