Description

Technical Field

[0001] The present invention relates to the technical field of die mechanisms, and in particular to a movable micro switch.

Background Art

[0002] In the process of forming a product by 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 retracted first and then the other mechanisms are closed. For example, Figure 1 As shown, after the ejector rod 20 is retracted, the return pin 30 pushes the ejector plate 50 to retract under the action of the elastic member 40. However, when the ejector plate 50 retracts, the micro switch pressing plate 60 on the ejector plate 50 easily presses and damages the micro switch 80 on the fixed plate 70, resulting in the failure of the micro switch 80 during the die closing process, that is, the micro switch 80 cannot give a machine signal after the ejection mechanism is fully retracted, resulting in the die being unable to perform the next die closing operation, that is, affecting the production process of the product.

[0003] In view of this, it is necessary to provide a movable micro switch 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 micro switch pressing plate easily presses and damages the micro switch, resulting in the failure of the micro switch during the die closing process, that is, the micro switch cannot give a machine signal after the ejection mechanism is fully retracted, resulting in the die being unable to perform the next die closing operation, that is, affecting the production process of the product. Therefore, the present invention provides a movable micro switch to solve the above problems.

[0005] The solution of the present invention to solve its technical problem is: a movable micro switch, comprising:

[0006] A fixed plate, which is fixed on one side of the machine table. The fixed plate is provided with a round hole through which the ejector rod can pass and then act on the ejector plate;

[0007] An ejector plate, which can move in the male die under the action of the ejector rod. A micro switch is fixed on one side of the ejector plate. The micro switch is provided with a convex point, and the convex point can be pressed down by a pressing plate to connect the power supply. One end of the ejector plate is provided with an elastic member, and a return pin is arranged in the elastic member. The ejector plate can drive the micro switch to eject the product together under the action of the ejector rod. When the ejector rod retracts, the return pin drives the ejector plate to retract under the action of the elastic member until the ejection mechanism is fully retracted. Then, the convex point of the micro switch fixed on the ejector plate is pressed by the pressing plate to connect the power supply, giving a signal that the ejection mechanism of the machine table is fully retracted, so that the die can perform the next die closing operation;

[0008] A male template, on one side of which a pressing plate is movably arranged. The pressing plate is provided with a movable hole, and a fixing member is arranged in the movable hole. The pressing plate can adjust the error distance when contacting the microswitch by moving on the fixing member.

[0009] Preferably, the number of fixing members in the movable hole can be set arbitrarily according to requirements.

[0010] Preferably, the number of fixing members in the movable hole is optimally two, which can not only make the pressing plate act more stably but also save materials.

[0011] Preferably, the fixing member can be a screw.

[0012] Preferably, the length of the pressing plate can be set with corresponding specifications according to the distance ejected by the ejection mechanism.

[0013] Preferably, the elastic member can be a spring.

[0014] The beneficial effect of the present invention is that through a movable microswitch, the microswitch is fixed on the ejection plate, and at the same time, the pressing plate is arranged on the male template. When the ejection mechanism ejects, the ejection plate drives the microswitch to eject the product together under the action of the ejector rod. When the ejection mechanism returns, the return pin drives the ejection plate to return under the action of the elastic member. After the ejection mechanism is completely returned, the convex point of the microswitch fixed on the ejection plate is connected to the power supply under the action of the pressing plate, giving a signal that the ejection mechanism of the machine tool is completely returned, so that the mold performs the next mold closing action and completes the production process of the product.

Detailed Embodiment

[0019] To further elaborate on the technical means and effects adopted by the present invention, the following describes in detail in combination with the embodiments of the present invention and their accompanying drawings.

[0020] The present invention provides a movable microswitch, including:

[0021] Fixed plate 200, the fixed plate 200 is fixed to one side of the machine table (not shown in the figure). The fixed plate 200 is provided with a circular hole (not shown in the figure), and the ejector rod 201 can pass through the circular hole and then act on the ejector plate 210;

[0022] Ejector plate 210, the ejector plate 210 can move within the male mold 300 under the action of the ejector rod 201. A micro switch 211 is fixed to one side of the ejector plate 210. The micro switch 211 is provided with a convex point 212. The convex point 212 can be pressed down by the pressure plate 222 and then the power supply is turned on. One end of the ejector plate 210 is provided with an elastic member 213, and a return pin 214 is arranged inside the elastic member 213. The ejector plate 210 can drive the micro switch 211 to eject the product together under the action of the ejector rod 201. When the ejector rod 201 returns, the return pin 214 drives the ejector plate 210 to return under the action of the elastic member 213. After the ejector mechanism is completely retracted, the convex point 212 of the micro switch 211 fixed on the ejector plate 210 is turned on by the pressure plate 222, giving a signal that the ejector mechanism of the machine table (not shown in the figure) is completely retracted, so that the mold performs the next mold closing action;

[0023] Male template 220, a pressure plate 222 is movably arranged on one side of the male template 220. The pressure plate 222 is provided with a movable hole 221, and a fixing member 223 is arranged inside the movable hole 221. In this embodiment, there are two groups of the fixing members 223, which can not only make the pressure plate 222 act more stably but also save materials. The pressure plate 222 can adjust the error distance when the pressure plate 222 contacts the micro switch 211 through the fixing member 223 (there may be an error when processing the position of the micro switch 211).

[0024] Among them, any number of fixing members 223 can be arranged in the movable hole 221.

[0025] Among them, the fixing member 223 can be a screw.

[0026] Among them, the length of the pressure plate 222 can be set with corresponding specifications according to the ejection distance of the ejector mechanism.

[0027] Among them, the elastic member 213 can be a spring.

[0028] The beneficial effects of the present invention are as follows. The present invention adopts a movable microswitch, which fixes the microswitch 211 on the ejector plate 210, and at the same time sets the pressure plate 222 on the male mold plate 220. When the ejector mechanism ejects, the ejector plate 210 drives the microswitch 211 to eject the product under the action of the ejector rod 201. When the ejector mechanism returns, the return pin 214 drives the ejector plate 210 to return under the action of the elastic member 213. After the ejector mechanism completely returns, the convex point 212 of the microswitch 211 fixed on the ejector plate 210 is in contact with the power supply under the action of the pressure plate 222, giving a signal that the ejector mechanism of the machine (not shown in the figure) has completely returned, so that the mold performs the next mold closing action to complete the production process of the product.

[0029] It should be noted that the present invention is not limited to the above embodiments. Any simple modifications, equivalent changes and modifications made by any person skilled in the art to the above embodiments based on the technical solution of the present invention fall within the protection scope of the present invention.
