Problems solved by technology

So far, the mold testing method for precision injection molds is still "by visual inspection and experience". Therefore, it is very dependent on the experience of workers, which is very easy to cause wrong mold testing and wrong repair. In order to obtain reasonable parameters, it is necessary to Multiple trial molds are carried out, which virtually increases the trial mold time and the cost of mold repair

Embodiment Construction

[0016] In order to make the present invention more comprehensible, a preferred embodiment is described in detail below with accompanying drawings.

[0017] The invention provides a method for testing a precision injection mold, the steps of which are as follows:

[0018] Step 1. Mold water flow measurement Connect the water groups on the trial-manufactured precision molds, and confirm that the water flow is a path. If it is not a path, check the water flow group of the mold. If it is a path, use water pipes to measure the flow rate. The meter is connected in series to each group of water delivery of the precision mold, and the flow value of each group of delivery water is read separately. If the flow value is less than the set value, the water delivery group corresponding to the flow value is detected, otherwise, go to the next step;

[0019] Step 2. Get the reasonable injection speed of the injection molding machine

[0020] Step 2.1. Clamp the precision mold into the clampi...

Abstract

The invention provides a mould testing method for a precise injection mould. The method is characterized by comprising the following steps of: 1, measuring the water transport flow of the mould; 2, obtaining a reasonable ejection speed of an injection moulding machine; 3, performing a glue balance test; 4, performing a pressure maintaining time test; and 5, ending the mould test. Through the mould testing method for a precise injection mould provided by the invention, the traditional mode of determining the mould repairing scheme through subjective judgment of people is changed, and the technology for a mould test of all mould testing workers is set to form a uniform standard; and thus, a reasonable technology for injection moulding can be directly found out without unnecessary efforts, and the defects of the mould can be discovered in time. The cost of twice mould tests can be saved for each set of mould on average (the repairing cost is saved since the mould testing times is reduced).

Description

technical field [0001] The invention relates to a mold testing method of a precision injection mold. Background technique [0002] The production process of precision injection molds generally consists of trial production, mold testing, mold repair and mass production. Among them, the trial mold stage is very important in the whole production process. Through the trial mold, we can know whether the trial mold can meet the requirements, and obtain the necessary parameters for using this mold to produce parts. So far, the mold testing method for precision injection molds is still "by visual inspection and experience". Therefore, it is very dependent on the experience of workers, which is very easy to cause wrong mold testing and mold repair. In order to obtain reasonable parameters, it is necessary to Carrying out multiple mold trials virtually increases the mold trial time and the cost of mold repair. Contents of the invention [0003] The purpose of the present invention...
