After finding the corresponding mold factory, all customers who have opened injection mold are most concerned about the price of injection mold. The price of the mold is inaccurate, and it is an irresponsible quotation to say it badly. So what factors affect the price of injection molds? 1. Material cost (the selection of materials and the heat treatment process have a greater impact on the price)

Many customers report that the plastic mold has passed the acceptance inspection, why there are unexpected quality abnormalities in the mold injection molding process. First of all, it is necessary to confirm that the quality problems in the injection molding process of the mold are often directly related to the quality of the mold. For example, if the mold clamping of the mold (referred to as the Fit mold) is not done well and is not precise enough, then the phenomenon of the product cloak may occur; or the thimble in the mold is not done precisely enough, and the problem of easy needle breakage may often occur. ...

After the injection molded part is demolded, the demolding mechanism needs to return to its original position to facilitate the demoulding after the next injection molded part is molded. There are many forms of reset mechanism, and the commonly used one is to use the return rod to play the role of reset. When demoulding, the push rod can push the injection part out of the mold; when the mold is closed, the fixed template pushes the return rod to realize the reset of the demoulding mechanism. (1) Screw-type reset rod reset mechanism: When the mold is closed, the reset of the push rod is completed by the reset screw.

1. The design of gate condensate pulling and stripping forms. The pulling rod is divided into gate pulling rod and runner pulling rod. Gate pulling rod and runner pulling rod are both used for falling off condensation. expected. In addition, a cold material hole is often opened at the end of the pulling rod to store the condensed material. 1. Gate pull rod: The gate pull rod is used to cut off the gate material and fall off the gate condensate. 2. The runner pulling rod: the runner pulling rod is used to drop the condensate from the runner.

The injection molded parts in the manual de-threading rack are stopped by the gate condensate or the wrench. When the structure of the injection mold needs to be simplified, manual de-threading is used, which is only suitable for single-piece and small-batch injection molding production. The de-threading rack is a universal manual de-threading device. When in use, the injection mold and the de-threading frame are installed together, the tail of the threaded core is installed in the joint, and the injection molded part can be demolded from the threaded core by shaking the shaft by hand. There are various forms of joints, and the exchange of joints can remove the threads of different injection parts.

(1) Bounce-open secondary demoulding mechanism: The injection molded part has two inner cavities, of which the inner layer is the deeper cavity. When the primary demoulding mechanism is used to produce deformation and cracking, the primary demoulding of the injection molded parts relies on the action of the spring to complete the demoulding of the deep inner cavity; the secondary demoulding is performed by the push rod under the action of the ejector rod mold. In this way, the deformation of the injection molded part during demolding can be reduced. When the fixed and movable molds are opened to a certain distance, due to the action of the spring, the moving mold plate moves a distance, and the injection molded parts come out of the core.
