本発明は、樹脂（プラスチック）Ｉｔｉ品を射出成形法
で製造するとき使用する鋳型の製造法に関する。DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a method for manufacturing a mold used when manufacturing resin (plastic) Iti products by injection molding.

樹脂製品を取り出すのである。An outline of the injection molding method will be described with reference to FIG. 2, which shows a cross-sectional view of a configuration example of an injection molding machine for thermoplastic resin and a mold. That is, resin is put in from a hopper 1, heated by a heater 2 and transported forward by a screw 3, air that has also entered the hopper is removed by a vent 4, and is sent to the front while being mixed well. The resin thus obtained is introduced from the injection nozzle 5 through the resin injection conduit (runner) 6 of the mold 9 that is in close contact with the tip of the nozzle, and is introduced into the space between 9 and 9' to fill the space. The mold is bolted to a frame attached to the molding machine and can be opened and closed as needed. After the resin 7 introduced and filled into the mold is solidified by cooling, the mold is opened and the solidified resin product is taken out by operating the dowel pin 8 or injecting compressed air.

である。(b) Conventional technology Resin molding molds are made from steel, which has high performance such as strength, heat resistance, and fatigue resistance at high temperatures, as a base material, and are machined into the desired mold shape from the base material. It had been. The reason why steel was used as the base material was to extend the service life of the mold, but since it was carved from a highly hard base material, the number of man-hours required for cutting was increased.Therefore, Using steel as a base material is suitable for manufacturing molds for mass production of the same type of product, but is not suitable for manufacturing molds for small volume production of a wide variety of products. This is because costs, especially cutting costs, become large and have a significant impact on the price of the product.

いので切削加工の工数の短縮から来る利点は、総体的に
は大きな効果にならないという状態であった。Therefore, we attempted to reduce the amount of cutting by casting zinc alloy or cast iron into the general shape of the mold, but this method required sand manufacturing and high-temperature melting processes, etc. Producing the base material already costs a lot of money. In addition, since the casting shrinkage rate is large, it is necessary to use a method to produce a more precise shape with more accurate dimensions, and the casting surface of zinc alloys and cast iron is rough with pinholes and cavities. In order to maintain wear resistance and mold releasability, finishing of the mold surface is also required. Furthermore, the service life of molds made in this way is significantly shorter than that of steel molds, so the advantage of reducing the number of machining steps is not significant overall.

As a result, we focused on cement-bonded concrete and obtained the following knowledge: This concrete casting has high compressive strength (there is no casting shrinkage like cast iron or zinc alloy, and there is almost no cutting work). However, concrete molds have problems with heat conductivity, mold release, and wear resistance. .

Since cooling requires rapid heating in the case of thermosetting resin, it is necessary to have good thermal conductivity, and in order to easily take out the solidified resin from the mold as a product, it must have good mold releasability. Since the molded resin is injected into the mold, in order to extend the life of the mold, it is required to have good wear resistance, and these are issues that need to be solved.

Adds abrasion resistance and mold releasability, and if necessary, creates a second metal coating layer on top of the first layer metal coating to further improve abrasion resistance, mold releasability, thermal conductivity, etc. It is.

と同時に設置することが可能である。Concrete mixtures are usually made of gravel, crushed stone, cement, etc., but in order to improve mechanical properties such as strength and impact resistance, heat resistance, and thermal conductivity, metal flakes and carbon boron nitride may be used. It is also good to mix non-metallic pieces in shapes such as spheres, rods, tubes, and fibers. In addition, when manufacturing the mold base, i.e., when pouring concrete, resin injection conduits (launch), cooling conduits, bolts for attaching the mold to the casting machine, and mold displacement prevention for accurately applying pressure to the mating surfaces of split molds are used. It is possible to install parts such as pins at the same time as casting the base.

溶射法によることが操作簡単で好ましい。The metal of the first metal coating layer is not particularly limited, but it is necessary that it has good adhesion to the concrete and that the surface of the coating layer is smooth and can be attached to the concrete uniformly, so copper, aluminum, or any of these materials must be used. Since these metals have high thermal conductivity, the heat of the injected resin can quickly diffuse into the mold in the case of a thermoplastic resin.The opposite is true for a thermosetting resin. Heat is conducted from the heated mold to the resin.It also has mold releasability and wear resistance.In addition, it can be attached by any method such as blasting, chemical plating, or baking (there are no particular restrictions). However, it is preferable to use the △ thermal spray method because it is easy to operate.

がよい。The metal of the second metal coating layer may be any coating that further improves wear resistance, mold releasability, thermal conductivity, strength, etc. (There is no particular restriction, but for example, chemical nickel plating, high hardness, etc.) It is preferable to use chrome plating or a method in which silicon carbide (SiC) particles are dispersed in a nickel base such as Nikasil.

するので鋳凰の寿命も長く保つようになる。(e) Since the base of the working mold is concrete, a metal coating with good adhesion can be easily obtained on its surface by metal spraying or the like. Such a concrete casting base having a first layer of metal coating on its surface can be easily coated with metal as a second layer by further plating or the like on the surface of the first layer. The concrete foundry with a gold layer made in this way has particularly improved mold releasability, abrasion resistance, and thermal conductivity, and even if such a foundry is used for resin molding, it will not turn out to be a molded product. It becomes easier to separate from the mold, and the surface of the molded product is not damaged (also, the heat resistance is improved, so the life of the casting enamel is extended).

熱伝導性を向上させる事が出来る。In addition, the advantage of making the base of the mold from concrete is that there is no need for cutting, and when pouring the mold's shape, the cooling conduits, etc., are also cast into the cast iron. It is possible to improve the thermal conductivity of the concrete base with simple operations.

すことができる。In addition, prefabricated resin injection conduits (launch), tools for attaching to resin casting machines, parts for taking out solidified and molded products, etc. can also be cast together, and castings made of metal can also be cast. The number of man-hours can be greatly reduced compared to the production of a glazed base.
