Abstract

The invention relates to a plastic guardrail plate mould which comprises n layers of plastic rib passages, n+1 layers of molten plastic passages and molten plastic filling passages, wherein the n layers of plastic rib passages for arranging plastic ribs are molded inside the mould, the n+1 layers of molten plastic passages are used for molding molten plastics of a plate body, and the molten plastic filling passages for filling the molten plastics are communicated with the inlets of the molten plastic passages; the plastic rib passages and the molten plastic passages are alternately arranged, and each layer of plastic rib passage is clamped between the molten plastic passages; and the plastic rib passages and the molten plastic passages are converged at the molding outlet of a plastic guardrail plate at the outlet end of the mould, wherein the n is a natural number larger than or equal to 1. The invention solves the technical problem that the physical characteristic of the plastic ribs is difficult to ensure in the process of manufacturing the plastic guardrail plate containing the plastic ribs.

Description

technical field [0001] The invention relates to a mould, in particular to a mold for a plastic guardrail board and a molding process for a plastic guardrail board using the mold. Background technique [0002] Most of the existing guardrails are cement guardrails and metal guardrails, which are relatively firm in structure and can well withstand larger impact forces. However, it is precisely because of their firm structure that they are not easy to bend. When people collide with cement or metal guardrails, they are easily injured; moreover, cement and metal guardrails are relatively heavy and difficult to install; and the cost is high. For metal guardrails, its surface is prone to rust over time during use, especially on roads in coastal areas and other areas where the air contains more corrosive substances. [0003] The road guardrail that is simply made of pure plastic cannot meet the road safety standards due to the strength limitation of the existing type of plastic itse...
