DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Example 1

[0021] See also Figure 1 - Figure 4The present invention provides a technical solution: a mold for detecting the aperture of a plastic overmolded part, comprising a lower fixed plate 100, an upper fixed plate 101 is arranged above the lower fixed plate 100, and three groups of detection components 200 are vertically arranged on the surface of the upper fixed plate 101. The detection components 200 can be used to detect multiple apertures on the surface of the plastic overmolded product at the same time. If unqualified, they can be discovered in time, and the trouble and error of manual detection one by one are reduced, thereby improving the accuracy of the detection data of the aperture of the plastic overmolded part and the detection efficiency. Two positioning pins 106 are symmetrically arranged on the upper surface of the upper fixed plate 101. The positioning pins 106 can be used to perform preliminary guidance and positioning on the placed plastic overmolded product. A support plate 108 is horizontally arranged below the upper fixed plate 101, and a lifting cylinder 102 is provided on the upper surface of the support plate 108. The lifting cylinder 102 can change the height position of the middle plate 107.

[0022] The detection component 200 includes a go / no-go gauge pin 104 vertically mounted inside the upper fixed plate 101. The upper end of the go / no-go gauge pin 104 can be used to detect multiple apertures on the plastic-coated part. A spring 203 is provided below the go / no-go gauge pin 104. The spring 203 can be extended and retracted in conjunction with a slot-type photoelectric switch 204 to detect and give an alarm. A slot-type photoelectric switch 204 is provided at the lower end of the spring 203.

[0023] In this embodiment, preferably, the detection component 200 also includes a guide sleeve 201 fixed on the upper surface of the upper fixed plate 101. By using multiple sets of detection components 200, multiple apertures on the plastic-coated parts can be detected at the same time to determine whether the apertures are qualified. The upper end of the go / no-go gauge pin 104 passes through the upper fixed plate 101 and the go / no-go gauge pin 104 is exposed to the outside, and the lower surface of the upper fixed plate 101 is provided with a fixing ring 202 that is sleeved on the go / no-go gauge pin 104.

[0024] In this embodiment, preferably, a guide shaft 103 penetrating the support plate 108 is provided between the upper fixing plate 101 and the lower fixing plate 100 , and the guide shaft 103 can play a guiding and limiting role in the installation of the upper fixing plate 101 and the lower fixing plate 100 .

[0025] In this embodiment, preferably, the upper end of the go / no-go gauge pin 104 is sleeved with a pass ring mark and a stop ring mark, and the two marks can be used to extend into the aperture on the overmolded part for detection.

[0026] In this embodiment, preferably, an intermediate plate 107 sleeved on the guide shaft 103 is horizontally arranged above the support plate 108, and a linear bearing 105 sleeved on the guide shaft 103 is provided on the upper surface of the intermediate plate 107 to increase the linear movement stability of the intermediate plate 107.

[0027] In this embodiment, preferably, a bottom fixing plate 1071 is provided on the lower surface of the middle plate 107, and a piston rod 1072 is movably provided between the upper end of the middle plate 107 and the bottom fixing plate 1071. The extension of the piston rod 1072 can drive the height change of the bottom fixing plate 1071 and the middle plate 107.

[0028] In summary, the overmolded product is placed manually, and the product is initially guided and positioned and error-proofed by the left and right positioning pins 106. The initial position of the lifting cylinder 102 is the rising position, and the three detection holes on the surface of the overmolded product are detected by the three go / no-go gauge inspection pins 104. If the product can pass the go / no-go gauge inspection, the three go / no-go gauge inspection pins float downward and are compressed by the spring 203. The compressed spring 203 is detected by the slot-type photoelectric switch 204, and the piston rod 1072 inside the lifting cylinder 102 retracts to complete the product loading. On the contrary, if the overmolded product fails to pass the go / no-go gauge inspection, the piston rod 1072 inside the lifting cylinder 102 will not retract, and the product is judged to be NG. The above-mentioned whole process can complete the detection of multiple apertures on the overmolded product, reduce the trouble of manual inspection one by one, and reduce the error of manual operation, improve the accuracy and convenience of aperture detection on the overmolded product, and improve the efficiency of aperture detection of the overmolded product.

[0029] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
