Problems solved by technology

Due to the small size of the general electronic components, the size of the insulating tubes or insulating strips used to protect the electronic components is also small, and the processing by CNC machine tools will have a long processing cycle, low efficiency and high cost, and due to the plastic material Under normal temperature conditions, the toughness is not enough and it is prone to embrittlement. The insulating tubes or insulating strips processed by machine tools often have low surface finish and many burrs, and the product size is unstable and low in uniformity. In order to improve the surface finish And deburring, manual polishing or deburring is required, which virtually increases the production cost

Embodiment 1

[0026] The preprocessed product in this embodiment is an insulating strip.

[0027] A mold injection molding method for processing special plastic materials, comprising the following steps:

[0028] a), according to the structure and size of the insulating strip, make an injection mold for forming the product;

[0029] b), put the special plastic raw material into the baking machine, and bake it at a certain temperature for a period of time to remove the moisture in the special plastic raw material; in this embodiment, the internal temperature of the baking machine is controlled at 200 ° C, and the baking time for 4 hours;

[0030] c) Since the heating temperature of the high-temperature heating ring in a conventional injection molding machine is generally 270-300°C, while the heating temperature of a ceramic heating ring is 450-500°C, the special plastic raw material can only be completely dissolved at 360-380°C; The molding crystallization can only meet the requirements of...

Embodiment 2

[0041] The preprocessed product in this embodiment is an insulating tube.

[0042] A mold injection molding method for processing special plastic materials, comprising the following steps:

[0043] a), according to the structure and size of the insulating tube, make an injection mold for forming the product;

[0044] b), put the special plastic raw material into the baking machine, and bake it at a certain temperature for a period of time to remove the moisture in the special plastic raw material; in this embodiment, the internal temperature of the baking machine is controlled at 180°C, and the baking time for 4 hours;

[0045] c) Since the heating temperature of the high-temperature heating ring in a conventional injection molding machine is generally 270-300°C, while the heating temperature of a ceramic heating ring is 450-500°C, the special plastic raw material can only be completely dissolved at 360-380°C; The molding crystallization can only meet the requirements of use...

Abstract

The invention discloses a mold injection molding method used for processing special plastic materials. An injection mold and an injection molding machine are adopted to be matched; and by adjusting the work parameters of the injection molding machine, after dewatering treatment is performed on raw materials of the special plastic materials and the raw materials of the special plastic materials are injected into the injection mold at a high speed and under a certain temperature, cooling molding is performed so that products can be obtained. According to the mold injection molding method used for processing the special plastic materials, by means of batch production by the injection mold, the unification degree of the obtained products is high, the production period is greatly shortened, and the production efficiency is greatly improved; and meanwhile, the products produced by injection molding have the beneficial effects that the products are high in surface finish degree and dimensional precision, and free of burrs, subsequent manual polishing and deburring treatment is not needed, the technological process is reduced, the production efficiency is further improved, and the production cost is lowered.

Description

technical field [0001] The invention belongs to the technical field of special plastic material processing methods, and in particular relates to a mold injection molding method for processing special plastic material. Background technique [0002] Most electronic components in automation equipment are wearing parts. Therefore, almost all electronic components are protected by insulating tubes or insulating strips. [0003] Existing insulating pipes or insulating strips are generally processed by CNC machine tools using special plastic materials. Due to the small size of the general electronic components, the size of the insulating tubes or insulating strips used to protect the electronic components is also small, and the processing by CNC machine tools will have a long processing cycle, low efficiency and high cost, and due to the plastic material Under normal temperature conditions, the toughness is not enough and it is prone to embrittlement. The insulating tubes or insu...
