Problems solved by technology

At present, the mold matching method is to match the mold after all the molds are assembled. This common mold matching method has the following disadvantages: 1. There are gaps in the inserts, and the lack of sealing leads to problems such as flashing and flaking of the product, which affects the quality of plastic products. Appearance quality; 2. The temperature of the movable and fixed molds of the mold changes during the production process, resulting in a gap between the movable and fixed molds of the mold, and severe flashing on the parting line and the four corners of the product; 3. The appearance and quality of the product are affected And product processing success rate is low, increase manufacturing cost

[0028] Please refer to figure 1 , The embodiment of the present invention provides a thermal mold matching method, which is used for the initial matching of the processed fixed mold part and the movable mold part, and correcting the gap between the fixed mold part and the movable mold part. It can simulate the ambient temperature of the mold during the production process, and match the mold at this temperature, the sealing effect is good, the products produced after the mold matching have no flash and burr, and the appearance quality is high.

[0029] The hot mold matching method includes the following steps:

[0030] Step S101: heating the preset insert in the injection mold to a preset temperature.

[0031] Specifically, the preset temperature is the ambient temperature of the injection mold during production. In the existing technology, the fixed mold part and the movable mold part are matched at normal temperature, and the fixed mold part and the movable mold part are cl...

[0054] Please refer to figure 2 , the embodiment of the present invention provides a method for producing a mold, which is used for producing a mold. The mold production method includes a heat matching mold method. Wherein, the steps, principles and technical effects of the thermal mold matching method are the same as those of the first embodiment. For a brief description, for parts not mentioned in this embodiment, reference may be made to the corresponding content in the first embodiment.

[0055] The mold production method comprises the following steps:

[0056] Step S201: Processing and molding the injection mold.

[0057] Step S202: heating the preset insert in the injection mold to a preset temperature.

[0058] Step S203: closing the injection mold.

[0059] Step S204: Open the mold and measure the deformation of the preset insert after thermal expansion.

[0060] Step S205: Correct the gap between the injection mold and the preset insert according to the amount o...

Abstract

The invention provides a hot mold matching method and a mold production method, and relates to the technical field of molds. The mold production method comprises the following steps that a preset insert is heated in the injection mold to a preset temperature, then the injection mold is subjected to mold closing, then the mold is opened and the deformation amount of the preset mold insert after thermal expansion is measured, and finally the gap between the injection mold and the preset mold insert is corrected according to the deformation amount. Compared with the prior art, the thermal modeling method and the step of heating the preset insert in the injection mold to a preset temperature is adopted, the environment temperature of the mold in the production process can be simulated, the mold can be matched at the temperature, good in sealing effect, free of flash edges and burrs of products produced after mold distribution and high in appearance quality.

Description

technical field [0001] The invention relates to the technical field of moulds, in particular to a heat matching mold method and a mold production method. Background technique [0002] With the continuous improvement of people's living standards and the continuous progress of industrial technology, the application of plastic products is becoming more and more extensive, and people's requirements for the appearance quality of plastic products are getting higher and higher. However, the appearance quality of plastic products largely depends on the manufacturing level of plastic molds. At present, the mold matching method is to match the mold after all the molds are assembled. This common mold matching method has the following disadvantages: 1. There are gaps in the inserts, and the lack of sealing leads to problems such as flashing and flaking of the product, which affects the quality of plastic products. Appearance quality; 2. The temperature of the movable and fixed molds of...
