Description

Technical Field

[0001] The present invention relates to the technical field of die mechanisms, and in particular to a press-fit microswitch.

Background Art

[0002] In the process of molding products with a two-plate semi-open die, the product needs to be ejected after the die is opened. Therefore, when the die is closed, the ejection mechanism needs to be reset first and then the other mechanisms are closed. For example, Figure 1 as shown, after the ejector rod 20 is reset, the return pin 30 pushes the ejector plate 50 to return under the action of the elastic member 40. However, when the ejector plate 50 returns, the microswitch pressing plate 60 on the ejector plate 50 easily presses and damages the microswitch 80 on the fixed plate 70, resulting in the failure of the microswitch 80 during the die closing process, that is, the microswitch 80 cannot give a machine signal after the ejection mechanism is completely reset, resulting in the inability of the die to perform the next die closing action, that is, affecting the production process of the product.

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

Summary of the Invention

[0004] The technical problem to be solved by the present invention is that during the die closing process of a two-plate semi-open die, the microswitch pressing plate easily presses and damages the microswitch, resulting in the failure of the microswitch during the die closing process, that is, the microswitch cannot give a machine signal after the ejection mechanism is completely reset, resulting in the inability of the die to perform the next die closing action, that is, affecting the production process of the product. Therefore, the present invention provides a press-fit microswitch to solve the above problems.

Detailed Implementation Manner

[0020] To further elaborate on the technical means and effects adopted by the present invention, the following describes it in detail in combination with the embodiments and accompanying drawings of the present invention.

[0021] The present invention provides a press - type micro - switch, including:

[0022] A fixed plate 100, which is fixed on one side of a machine table (not shown in the figure). The fixed plate 100 is provided with a circular hole (not shown in the figure). The circular hole (not shown in the figure) can allow a circular hole 101 to pass through it and then act on an ejection plate 110. A micro - switch adjustment plate 102 is movably arranged on the fixed plate 100. The micro - switch adjustment plate 102 is provided with an adjustment hole 103. A first fixing member 104 is arranged in the adjustment hole 103. In this embodiment, two groups of the first fixing members 104 can be provided, which can not only make the micro - switch adjustment plate 102 act more stably but also save materials. The micro - switch adjustment plate 102 can adjust the error distance when the pressing plate 112 presses down the micro - switch 105 (there may be an error when processing the position of the micro - switch 105) through the first fixing member 104 moving in the adjustment hole 103. A micro - switch 105 is fixed on the micro - switch adjustment plate 102. The micro - switch 105 is provided with a convex point 106, and the convex point 106 can be pressed down by the pressing plate 112 to connect the power supply thereafter;

[0023] Ejector plate 110, the ejector plate 110 can move within the male mold 200 under the action of the ejector rod 101. One end of the ejector plate 110 is connected with a pressing plate 112 through a first elastic member 111. The pressing plate 112 is provided with a moving hole 113, and a second fixing member 114 is arranged in the moving hole 113. In this embodiment, there are two groups of the second fixing members 114, which can not only make the pressing plate 112 act more stably but also save materials. The pressing plate 112 can move on the second fixing member 114 through the first elastic member 111. One end of the ejector plate 110 is provided with a second elastic member 115, and a return pin 116 is arranged in the second elastic member 115. When the ejector rod 101 pushes the ejector plate 110 to move, the ejector plate 110 drives the pressing plate 112 to eject the product together. When the ejector rod 101 returns, the return pin 116 drives the ejector plate 110 to return under the action of the second elastic member 115. At the same time, when driving the pressing plate 112 to move to the convex point 106 of the micro switch 105, the pressing plate 112 moves on the second fixing member 114 through the first elastic member 111. After the ejector mechanism is completely retracted, the pressing plate 112 presses the convex point 116 of the micro switch 105, so that after the power supply is connected, a signal that the ejector mechanism of the machine tool (not shown in the figure) is completely retracted is given, and the mold performs the next mold closing action.

[0024] Wherein, the number of the first fixing members 104 in the adjusting hole 103 can be set arbitrarily according to requirements.

[0025] Wherein, the number of the second fixing members 114 in the moving hole 113 can be set arbitrarily according to requirements.

[0026] Wherein, both the first fixing member 104 and the second fixing member 114 can be screws.

[0027] Wherein, the size of the moving hole 113 can be set with corresponding specifications according to the ejection distance of the ejector mechanism.

[0028] Wherein, both the first elastic member 111 and the second elastic member 115 can be springs.

[0029] The beneficial effect of the present invention is that through a pressing type micro switch, the present invention adds a first elastic member 111 on the ejector plate 110 to cooperate with the pressing plate 112 to move on the second fixing member 114, so that when the ejector mechanism returns, the convex point 106 of the micro switch 105 can be pressed by the pressing plate 112. After the micro switch 105 is powered on, a signal that the ejector mechanism of the machine tool (not shown in the figure) is completely retracted is given, and the mold performs the next mold closing action to complete the production process of the product.

[0030] It should be noted that the present invention is not limited to the above embodiments. Any simple modifications, equivalent changes and modifications made by those skilled in the art to the above embodiments based on the technical solutions of the present invention all fall within the protection scope of the present invention.
