Description

Technical Field

[0001] The utility model relates to the technical field of plastic molds, in particular to a mold limit switch verifier. Background Art

[0002] In the plastic mold industry, limit switches are crucial components for ensuring safe mold operation. Traditional testing methods typically require installing the mold on the injection molding machine and inspecting it while it's operating to confirm whether the limit switches are functioning properly. However, this method has limitations, such as requiring significant time and labor costs. Furthermore, a malfunctioning limit switch during testing could potentially damage the machine's circuit boards, leading to additional financial losses.

[0003] Furthermore, because limit switches are typically located inside the mold, checking their working status is complex and difficult, further increasing the difficulty of detection. If a limit switch malfunction is not detected in time, it will have a serious impact on subsequent production activities and may even lead to safety accidents. Utility Model Content

[0004] The purpose of the utility model is to provide a mold limit switch verifier, which can complete the inspection of the limit switch status before the mold is installed on the injection molding machine, so as to ensure that the limit switch can work normally and avoid unnecessary losses and risks.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0006] A mold limit switch verifier includes a mounting box, a junction box arranged on the mounting box, a status indicator light, a battery for supplying power to the status indicator light, and a test signal line;

[0007] The junction box is provided with an interface, in which a plurality of PIN pins are provided. The shape of the interface matches the plug of the limit switch, and the positions of the PIN pins correspond to the sockets on the limit switch plug.

[0008] The status indicator light is electrically connected to at least three wires, including a first wire, a second wire, and a third wire, wherein the first wire and the second wire are respectively connected to the positive and negative poles in the plug, and the third wire is connected to the test signal line;

[0009] The first wire and the second wire are respectively connected to the pins of the first state conduction circuit of the status indicator light, and the first wire and the third wire are respectively connected to the pins of the second state conduction circuit of the status indicator light;

[0010] One end of the test signal line is connected to the third wire, and the other end is a free end, and the free end is made of conductive material.

[0011] Furthermore: the installation box is made of insulating material.

[0012] Furthermore: the installation box is made of transparent acrylic material.

[0013] Furthermore: in the first state, the status indicator light is green.

[0014] Furthermore: in the second state, the status indicator light is red.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. Improve detection efficiency: The limit switch verifier can quickly verify the status of the limit switch before the mold is installed on the injection molding machine. Plug in the limit switch plug and press the limit switch. If the status indicator light indicates the first state, the limit switch is open and closed normally. Then connect the test signal line to the mold. If the status indicator light indicates the second state, the limit switch is short-circuited. By observing the status indicator light, you can detect whether the limit switch is open and closed normally or short-circuited. This avoids the traditional method of installing the mold on the injection molding machine and starting it to detect whether the limit switch is normal, significantly improving detection efficiency.

[0017] 2. Reduce equipment damage: By setting an interface that matches the limit switch plug on the junction box and using different colors of the status indicator to indicate the status of the limit switch, problems with the limit switch can be discovered before the machine is put on, avoiding the possibility of the injection molding machine circuit board burning due to limit switch failure and reducing the risk of equipment damage.

[0018] 3. Simplified operation process: The limit switch verifier is easy to operate. You only need to insert the limit switch into the junction box interface and judge the status of the limit switch by observing the color change of the status indicator light. There is no need for complicated detection steps, which simplifies the operation process and reduces the difficulty of operation.

[0019] 4. Improve safety: The installation box is made of insulating materials, especially transparent acrylic, which not only provides good insulation performance, but also facilitates observation of the internal structure, thereby improving safety of use. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] like Figure 1 Shown: A mold limit switch verifier includes a mounting box 2, a junction box 3 arranged on the mounting box 2, a status indicator light 1, a battery for supplying power to the status indicator light 1, and a test signal line 7; the mounting box 2 is made of transparent acrylic material.

[0026] The junction box 3 is provided with an interface, in which a plurality of PIN pins 4 are provided. The shape of the interface matches the plug 5 of the limit switch 6, and the position of the PIN pins 4 corresponds to the jack on the plug 5 of the limit switch 6;

[0027] The status indicator light 1 is electrically connected to at least three wires, including a first wire, a second wire and a third wire, wherein the first wire and the second wire are connected to the positive and negative poles in the plug 5 respectively, and the third wire is connected to the test signal line 7;

[0028] The first wire and the second wire are respectively connected to the pins of the first state conductive circuit of the status indicator light 1, and the first wire and the third wire are respectively connected to the pins of the second state conductive circuit of the status indicator light 1; in the first state, the status indicator light 1 lights up green; in the second state, the status indicator light 1 lights up red.

[0032] Press the limit switch 6. If the status indicator light 1 turns green, it means that the opening and closing functions of the limit switch 6 are normal. This means that there is no short circuit or other electrical faults in the limit switch 6.

[0033] One end of the test signal line 7 is connected to the third wire, and the other end is in contact with any part of the mold.

[0034] If the limit switch 6 is short-circuited to the ground, the status indicator light 1 will light up red through the conductive loop formed by the first and third wires. At this time, the user can judge whether the limit switch 6 is normal or has a short-circuit problem by observing the color change of the status indicator light 1.
