Description

Technical Field

[0001] The embodiment of the utility model relates to the technical field of injection molds, and in particular to an insert injection molding carrier slider. Background Art

[0002] In the injection mold industry, insert-type injection molding products have been widely used in automotive and communication connectors. With the advancement of technology, the structure of connector products has become more and more complex, especially for some insert-type injection molding products. It is difficult to directly implant the insert terminal into the mold. Instead, it is necessary to assemble the insert terminal outside the mold with the help of a carrier and then put it into the mold for injection molding. In the prior art, the insert terminal is usually fixed on the carrier slider first, and then the carrier slider is placed in the mold to ensure that the insert terminal can be effectively fixed in the mold for injection molding.

[0003] Because the carrier slider places the insert terminal outside the mold, it is bound to cause the temperature of the carrier slider to be mismatched with the temperature inside the mold, and a heating device (heating coil) is required for heating. However, when the carrier slider equipped with the insert terminal is placed in the heating coil for heating, the carrier slider and the insert terminal are made of different materials, and the heat absorbed during the heating process is also different, causing the insert terminal to deform during the heating process due to uneven heating. Therefore, how to ensure that the temperature of the insert terminal and the mold body is consistent is an urgent problem to be solved.

[0004] Therefore, it is necessary to provide a new insert injection molding carrier slider to overcome the above-mentioned defects. Utility Model Content

However, it can be understood by those skilled in the art that in the implementation mode of the utility model, many technical details are proposed in order to make the reader better understand the present application. However, even without these technical details and various changes and modifications based on the following implementation modes, the technical scheme claimed in the present application can be implemented.

[0018] See also Figures 1 to 3 The figure shows an insert injection molding carrier slider 100 of the utility model, which is used to clamp a plurality of metal terminals 200 and is placed in an injection mold. The metal terminal 200 is provided with a slender main body 201 extending in the longitudinal direction, a positioning hole 202 penetrating the main body 201, and a notch 203 located on one side of the main body 201 in the transverse direction.
