Abstract

The invention discloses a mirror surface insert mold. The mirror surface insert mold comprises a bottom plate and ejector pin fixing assemblies, wherein the ejector pin fixing assemblies are arranged on the upper surface of the bottom plate and composed of ejector pin bottom plates and ejector pin panels. The four corners of the upper surface of each ejector pin fixing assembly are provided with return pins which are sleeved with springs. The middle of the upper surface of each ejector pin fixing assembly is further provided with a plurality of fixed ejector pins, ejector sleeves and flat ejector pins, wherein the ejector pins, the ejector sleeves and the flat ejector pins penetrate through the two sets of the ejector pin fixing assemblies. Stop bolts are arranged in the position, close to the ejector pin bottom plates, of the upper surface of the bottom plate. Two square irons are symmetrically arranged in the position, close to the stop bolts, of the upper surface of the bottom plate. Guide posts are arranged on the upper surfaces of the stop bolts. The outer surfaces of the guide posts are sleeved with guide sleeves. A B plate is arranged on the tops of the guide posts. The upper surface of the B plate is sequentially provided with a back mold core, a front mold core, an A plate, a top clamp plate and a panel from bottom to top. A vertical downward sprue is arranged on the top of the panel. According to the mirror surface insert mold, the mirror surface insert mold can be well processed and completed, and the processing accuracy of the mold is ensured.

Description

technical field [0001] The invention belongs to the field of mold processing technology, and in particular relates to a mirror insert mold and a preparation technology thereof. Background technique [0002] With the development of the times, the requirements for the mirror surface of the mirror products and transparent lenses on the car are getting higher and higher, which makes it more and more difficult to produce the mirror products. If the mirror surface of the mold itself is insufficient, it is impossible to produce high requirements. Therefore, how to produce a high-demand mirror insert mold is the key to solving the problem. In the prior art, the production is mainly carried out by polishing after the rough molding of the mold. However, the negligence of many key points during production makes the mirror insert mold produced in the prior art fail to meet the requirements. Contents of the invention [0003] The technical problem to be solved by the present invention...
