Manufacturing method of temperature control injection mold

Abstract

The invention discloses a manufacturing method of a temperature control injection mold, comprising the specific steps of designing the mold, making an engineering drawing, machining a mold body, performing soaking treatment in vegetable oil, performing heat treatment, arranging an electrical heating element, packaging the electrical heating element, arranging a magnetic guide ring and performing aftertreatment; during mold design, 3D modeling is performed on various structural parts of the mold, a general assembly drawing of the mold is made for machining the mold body, the mold body is machined, and groove structures are machined on a formed upper mold body and a formed lower mold body. A mold prototype drawing is subjected to CAD design, the problems occurring in practical machining can be avoided according to a simulation analysis of the drawing, the manufacturing method is simple and convenient to implement, and moderate in cost, the plurality of groove structures are made on an upper mold and a lower mold by machining, and are used for arranging the electrical heating element, the electrical heating element is matched with an external electrical heating device to be used, and temperature conditioning of the mold can be effectively realized; meanwhile, the electrical heating element is reasonable in arrangement and packaging, and stable in usability, so that the heating and thermal insulation properties of the injection mold are more outstanding.

Description

technical field [0001] The invention relates to the technical field of injection mold manufacturing, in particular to a method for manufacturing a temperature-controlled injection mold. Background technique [0002] Injection mold is a tool for producing plastic products, and it is also a tool for giving plastic products complete structure and precise dimensions. The injection mold consists of two parts, the movable mold and the fixed mold. The movable mold is installed on the movable template of the injection molding machine, and the fixed mold is installed on the fixed template of the injection molding machine. During injection molding, the movable mold and the fixed mold are closed to form the gating system and the mold Cavity, when the mold is opened, the movable mold and the fixed mold are separated to take out the plastic product. There are many types of injection molds, which can be divided into thermosetting plastic molds and thermoplastic plastic molds according to...

Problems solved by technology

[0007] (1) Since the teeth of the upper and lower magnetic conducting rings are relatively placed, the positioning of the magnetic conducting ring through the cooperation of the positioning hole and the guide post is only a positioning in the vertical direction between the upper and lower magnetic conducting rings, while the upper and lower magnetic conducting rings When the rings are placed relative to each other, the teeth are relatively occluded. This positioning method cannot guarantee the accuracy of the alignment of the teeth of the upper and lower magnetic rings, thus affecting the performance of the product.

[0008] (2) In order to realize the positioning between the upper and lower magnetic rings, a positioning hole is provided on the magnetic ring, which hinders the magnetic path on the magnetic ring, makes the magnetic field distribution uneven, and affects the effect of magnetic field induction; Moreover, at the positioning hole, the mechanical strength is also low, and the micro-deformation that will occur when the stress is applied here will cause the magnetic circuit to break, which will affect the effect of magnetic field induction, thereby reducing the consistency and reliability of the sensor, and greatly Reduces the accuracy of the signal delivered by the sensor

[0009] (3) The local temperature control effect is not good, and the precision is not high, which affects the molding quality of the local details of the product
