Problems solved by technology

Since the hole size of the embedded screw hole on the injection mold is fixed, and the size of the embedded screw has a certain range of error, some embedded screws have a large gap when installed in the mold, and some embedded screws cannot be installed in the corresponding hole of the mold. Here, when this method is used, the work efficiency of injection molding production is relatively low, and it will cause inconvenience during operation, thereby increasing production costs
The pre-embedded screws are installed too tightly in the injection mold, which will have a great impact on the ejection of the mold, and will also cause whitening and even cracking of the plastic products.

Embodiment Construction

[0009] See attached figure 1 , figure 2 , The inspection tool for embedded screws of the present invention includes: a mounting plate 1 and an embedded screw detection hole 2 . In order to ensure the accuracy requirements of the embedded screw detection hole diameter, 10 embedded screw detection holes 2 are machined on the mounting plate 1 through slow wire cutting, and the standard embedded screw size within the range of M3 to M8 can be adjusted. detection. The size of the pre-embedded screw detection hole 2 corresponds to different tolerance ranges. When the embedded screw is in use, according to the specification of the embedded screw, according to the type marked on the mounting plate 1, it is put into the embedded screw detection hole 2 for detection. If the pre-embedded screw can pass through the detection hole 2 on the mounting plate 1, it means that the size of the pre-embedded screw meets the tolerance requirements of the design, and it is a qualified part; The s...

Abstract

A checking tool for checking embedded screws comprises a mounting plate (1) and 10 embedded screw detection holes (2). The checking tool is characterized in that the embedded screw detection holes (2) are made in the mounting plate (1) by wire-cut electrical discharge machining. The sizes of the embedded screw detection holes (2) are correspondingly in different tolerance ranges of M3 to M8; the sizes of standard embedded screws in the ranges of M3 to M8 are detected. The checking tool is simple, can run stably and reliably and allows the sizes of the embedded screws to be conveniently and quickly detected; the embedded screw detection holes in the checking tool are applicable to detecting the sizes of the standard embedded screws in the ranges of M3 to M8; the problem that the sizes of the existing embedded screws have errors in certain ranges, thereby resulting in significantly decreased injection molding productivity, is solved.

Description

technical field [0001] The invention relates to a detection tool for standard parts, in particular to a detection tool for the size of pre-embedded screws installed on plastic products. Background technique [0002] Many plastic products need to be assembled with other parts. In order to ensure the strength of the plastic products after assembly, in the process of injection molding of plastic products, the mounting parts of the plastic parts are generally embedded with embedded screws. Since the hole size of the embedded screw hole on the injection mold is fixed, and the size of the embedded screw has a certain range of error, some embedded screws have a large gap when installed in the mold, and some embedded screws cannot be installed in the corresponding hole of the mold. Here, when this method is used, the work efficiency of injection molding production is relatively low, and it will cause inconvenience during operation, thereby increasing production costs. The pre-embed...
