Description

Technical Field

[0001] The utility model relates to the technical field of switches, in particular to an induction switch for a mold. Background Art

[0002] A proximity switch is a sensor that can detect objects approaching it. It is widely used in industrial sites. As the name implies, as a switch, it can output two results: 0 or 1. According to different working principles, proximity switches can be divided into inductive and photoelectric (mainly infrared). For an inductive proximity switch, when iron metal approaches it, the iron metal is easily magnetized. The magnetization process absorbs the energy of the high-frequency magnetic field. The detection circuit inside the proximity switch can detect the change in the state of the oscillation circuit, thereby changing the output state and changing the signal value of the proximity switch from 0 to 1. When non-iron metals (such as aluminum, copper, etc.) approach the inductive proximity switch, they do not absorb the energy of the high-frequency magnetic field. On the contrary, this type of metal can also increase the frequency of the internal oscillation circuit of the proximity switch. The internal detection circuit can also detect this change, thereby changing the output state and changing the signal value of the proximity switch from 0 to 1.

[0003] Existing mold designs often use induction switches, which are mainly used to monitor whether the mold's operating movements are in place. As long as the induction switch alarms, the mold will stop operating to avoid damage to the mold due to a certain movement of the mold not being in place, thereby protecting the mold. For example, Chinese patent announcement No. CN207172622U discloses "an injection mold", which cooperates with the induction switch fixed on the bottom plate by rotating the contact connected to the ejector plate. The outer periphery of the contact has a number of contact points with different distances from the rotation axis of the contact. The user can rotate the contact to select a suitable contact point to cooperate with the induction switch, which reduces the requirements for installation accuracy to a certain extent, and can avoid the scrapping of the contact and the induction switch due to installation accuracy errors. The operation is simple and convenient, and the production cost is reduced.

[0004] However, in actual use, screws are usually used to detachably connect the induction switch to the mold, which results in the need to add screw holes to each set of molds. Some induction switches also require processing of installation grooves, which increases the difficulty and cost of processing. Utility Model Content

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] Reference Figure 1-4 , an induction switch for a mold, comprising a mold body 1, a switch device 2 and a trigger device 3, wherein a magnetic component 4 is disposed on one side of the switch device 2 and the trigger device 3 close to the mold body 1, and the magnetic component 4 is magnetically connected to the mold body 1;

[0028] The trigger device 3 is arranged above the switch device 2 and cooperates with the sensing end of the trigger device 3;

[0029] The switch device 2 is provided with an inductive switch body 5, and the inductive end of the inductive switch body 5 passes through the switch device 2 and corresponds to the trigger device 3;

[0030] A limiting mechanism 6 matched with the switch body 5 is provided in the switch device 2 .

[0031] In the utility model, a magnetic component 4 is provided on one side of the switch device 2 and the trigger device 3 close to the mold body 1, and the switch device 2 and the trigger device 3 are connected to the mold body 1 by magnetic attraction, which is convenient for installation and does not require the opening of mounting holes and mounting grooves, thereby reducing the processing difficulty and processing cost. In this embodiment, the magnetic component 4 includes a fixing frame and a magnet fixedly connected to the fixing frame, and the switch device 2 and the trigger device 3 are detachably connected to the magnetic component 4 by bolts.

[0032] Furthermore, in this embodiment, the limiting mechanism 6 includes a mounting groove 61 provided on the switch device 2 and matched with the sensing switch body 5, and a support frame 62 matched with the sensing switch body 5 is fixedly arranged in the mounting groove 61. The sensing switch body 5 is supported and limited by the support frame 62 to prevent it from moving left and right during use.

[0033] Furthermore, in the present embodiment, the limiting mechanism 6 also includes a clamping assembly 63 arranged on the support frame 62 for clamping the sensing switch body 5, and the clamping assembly 63 includes a first clamping plate 631 and two second clamping plates 632 connected to the support frame 62, and the first clamping plate 631 and the two second clamping plates 632 are both elastic plates, and the sensing switch body 5 is elastically clamped by the first clamping plate 631 and the two second clamping plates 632 to prevent the sensing switch body 5 from moving up and down.

[0034] It should be noted that, in the present embodiment, a limiting groove 64 is provided on the first clamping plate 631, and a wedge block 65 matching with the limiting groove 64 is provided at one end of the sensing switch body 5. Through the cooperation between the wedge block 65 and the limiting groove 64, after the sensing switch body 5 is installed, the lower end of the sensing switch body 5 contacts the supporting frame 62, and the upper end of the wedge block 65 contacts the limiting groove 64, so as to prevent the wedge block 65 and the sensing switch body 5 from moving upward, thereby preventing the sensing switch body 5 from moving up and down.

[0035] In addition, in the present embodiment, the wedge block 65 is movably connected to the induction switch body 5, and a first spring 66 cooperating with the wedge block 65 is provided in the induction switch body 5, so that when the induction switch body 5 is installed until the inclined surface of the wedge block 65 abuts against the first clamping plate 631 on the support frame 62, the wedge block 65 will be retracted into the induction switch body 5 to avoid obstructing the installation of the induction switch body 5.

[0036] In detail, in this embodiment, a second spring 67 is fixedly connected to the support frame 62, and an upper end of the second spring 67 is fixedly connected to a push plate 68 abutting against the sensing switch body 5. When the first clamping plate 631 is moved to separate the limiting groove 64 from the wedge block 65, the second spring 67 drives the push plate 68 to move upward to provide thrust for the sensing switch body 5, so that it moves upward and partially exceeds the switch device 2, making it easy to take out and replace.

[0037] In some embodiments, the induction switch body 5 and the switch device 2 are detachably connected via bolts.

[0038] In this embodiment, the switch device 2 includes a mounting portion 21 and a baffle 22. The baffle 22 is detachably connected to the mounting portion 21 and the magnetic component 4 in sequence by bolts, so that the baffle 22, the mounting portion 21 and the magnetic component 4 form an integrated structure, which is more stable and can be disassembled for maintenance when necessary.

[0039] Working method: When in use, the switch device 2 and the trigger device 3 are provided with a magnetic component 4 on one side close to the mold body 1, and the switch device 2 and the trigger device 3 are connected to the mold body 1 by magnetic attraction. The support frame 62 is used to support and limit the induction switch body 5 to prevent it from moving left and right during use. The first clamping plate 631 and the two second clamping plates 632 are used to elastically clamp the induction switch body 5 to prevent the induction switch body 5 from moving up and down;

[0040] During installation, when the induction switch body 5 is installed to the inclined surface of the wedge block 65 and abuts against the first clamping plate 631 on the support frame 62, the wedge block 65 will be retracted into the induction switch body 5 and squeeze the first spring 66 to avoid obstructing the installation of the induction switch body 5. In addition, during the installation process, the push plate 68 moves downward to drive the second spring 67 to undergo elastic deformation.

[0041] After the induction switch body 5 is installed, the first spring 66 is reset to drive the wedge block 65 to reset. At this time, the lower end of the induction switch body 5 contacts the support frame 62, and the upper end of the wedge block 65 contacts the limit groove 64 to prevent the wedge block 65 and the induction switch body 5 from moving upward, thereby preventing the induction switch body 5 from moving up and down.

[0042] When the induction switch body 5 is taken out for replacement, the first clamping plate 631 is moved to separate the limiting groove 64 from the wedge block 65, and the second spring 67 drives the push plate 68 to move upward to provide thrust for the induction switch body 5, so that it moves upward and partially exceeds the switch device 2, making it easy to take out for replacement.

[0043] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
