Description

[Technical Field]

[0001] This invention relates to the field of mold mechanism technology, and in particular to a press-fit micro switch. [Background Technology]

[0002] In the process of molding a product using a two-and-a-half-plate mold, the product needs to be ejected after the mold opens. Therefore, when closing the mold, the ejection mechanism must be returned to its original position before the remaining mechanisms are closed. Figure 1 After the ejector pin 20 returns to its original position, the return pin 30 pushes the ejector plate 50 to return to its original position under the action of the elastic element 40. However, when the ejector plate 50 returns to its original position, the micro switch pressure plate 60 on the ejector plate 50 may easily crush the micro switch 80 on the fixed plate 70, causing the micro switch 80 to fail during the mold closing process. That is, the micro switch 80 cannot give a machine signal after the ejector mechanism has fully returned to its original position, which makes it impossible for the mold to perform the next mold closing action, thus affecting the product production process.

[0003] In view of this, it is necessary to provide a press-fit micro switch to solve the above problems. [Summary of the Invention]

[0004] The technical problem this invention aims to solve is that during the mold closing process of a two-plate mold half-mold, the micro switch pressure plate is prone to damaging the micro switch, causing the micro switch to malfunction during mold closing. Specifically, the micro switch cannot provide a machine signal after the ejection mechanism has fully returned to its original position, preventing the mold from proceeding to the next mold closing operation and thus affecting the product manufacturing process. Therefore, this invention provides a pressure-operated micro switch to solve the above problem.

[0005] The solution to the technical problem of this invention is: a press-fit micro switch, comprising:

[0006] A fixed plate is fixed to one side of the machine base. The fixed plate has a circular hole through which a push rod passes and acts on the ejector plate. A micro switch adjustment plate is movably mounted on the fixed plate. The micro switch adjustment plate has an adjustment hole and a first fixing member is provided in the adjustment hole. The error distance when the pressure plate presses down on the micro switch can be adjusted by the first fixing member that moves in the adjustment hole. A micro switch is fixed on the micro switch adjustment plate. The micro switch has a protrusion. The protrusion can be connected to the power supply after being pressed down by the pressure plate.

[0007] An ejector plate is movable within the mold under the action of an ejector rod. One end of the ejector plate is connected to a pressure plate via a first elastic element. The pressure plate has a movable hole, and a second fixing element is provided in the movable hole. The pressure plate can move on the second fixing element through the first elastic element. One end of the ejector plate has a second elastic element, and a return pin is provided in the second elastic element. When the ejector rod pushes the ejector plate to move, the ejector plate drives the pressure plate to eject the product together. When the ejector rod returns to its original position, the return pin drives the ejector plate to return to its original position under the action of the second elastic element. At the same time, it drives the pressure plate to move to the protrusion of the micro switch. The pressure plate then moves on the second fixing element through the first elastic element until the ejection mechanism is fully returned to its original position. After that, the pressure plate presses down on the protrusion of the micro switch, so that it connects the power supply and gives a signal that the ejection mechanism of the machine is fully returned to its original position, so that the mold can proceed to the next mold closing action.

[0008] Preferably, the number of the first fixing members inside the adjustment hole can be set as needed.

[0009] Preferably, there are two first fixing members in the adjustment hole, which can not only make the micro switch adjustment plate operate more stably, but also save materials.

[0010] Preferably, the number of second fasteners within the movable hole can be set as needed.

[0011] Preferably, there are two second fixing members in the movable hole, which can not only make the pressure plate operate more stably, but also save materials.

[0012] Preferably, both the first and second fixing members can be screws.

[0013] Preferably, the size of the movable hole can be set according to the ejection distance of the ejection mechanism.

[0014] Preferably, both the first elastic element and the second elastic element can be springs.

[0015] The beneficial effect of the present invention is that it uses a press-fit micro switch, which employs a first elastic element added to the ejector plate to cooperate with the pressure plate moving on the second fixed element. When the ejector mechanism returns to its original position, the pressure plate can press down on the protrusion of the micro switch, so that the micro switch connects to the power supply and gives a signal that the ejector mechanism of the machine has fully returned to its original position, so that the mold can proceed to the next mold closing action and complete the product production process.

When the ejector rod 101 returns to its original position, the return pin 116 drives the ejector plate 110 to return to its original position under the action of the second elastic element 115. At the same time, it drives the pressure plate 112 to move to the protrusion 106 of the micro switch 105. The pressure plate 112 moves on the second fixing element 114 through the first elastic element 111 until the ejection mechanism is fully returned to its original position. Then, the pressure plate 112 presses down on the protrusion 116 of the micro switch 105 to turn on the power and give a signal that the ejection mechanism of the machine (not shown in the figure) is fully returned to its original position, so that the mold can perform the next mold closing action.

[0024] The number of first fixing members 104 inside the adjustment hole 103 can be set as needed.

[0025] The number of second fasteners 114 within the movable hole 113 can be set as needed.
