Abstract
Description
Technical Field
[0001] This utility model relates to the field of injection molding machine measurement technology, specifically to an LED measuring ruler for the injection stroke of an injection molding machine. Background Technology
[0002] Injection molding machines are the main molding equipment used to produce various shapes of plastic products from thermoplastic or thermosetting materials using plastic molds. The working principle of an injection molding machine is to inject pre-plasticized molten plastic into a closed mold cavity using the thrust of a screw or plunger, and then obtain the product after solidification and shaping.
[0003] During the injection process, it is necessary to accurately measure the injection stroke. Generally, electronic rulers are used with mechanical structures to measure the stroke. The stroke is obtained by the movement distance of the mechanical structure. Such electronic rulers have cumbersome structures and complex measurement processes. Utility Model Content
[0004] To solve the above technical problems, an LED measuring ruler for the injection stroke of an injection molding machine is provided.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an LED measuring ruler for injection stroke of an injection molding machine, comprising a measuring ruler body embedded in the surface of the injection mold cavity; the measuring ruler body is elongated and has a cavity, with scales on its outer surface and an electrical control component inside, the electrical control component having an LED cursor whose position changes with the injection stroke, the light source of which is projected onto the surface of the measuring ruler body.
[0006] According to this utility model, a slot is formed on the surface of the injection mold cavity to accommodate the measuring ruler body. The measuring ruler body is embedded in the slot and then welded and fixed. The length direction of the measuring ruler body is consistent with the length direction of the injection mold cavity.
[0007] According to this utility model, the measuring ruler body is further provided with a displacement sensor electrically connected to the electronic control component, which is used to obtain the injection volume of material in the injection mold cavity of the injection molding machine and transmit the data to the electronic control component. The electronic control component controls the LED cursor to move and display it on the outer surface of the measuring ruler body, so as to facilitate the acquisition of the injection stroke.
[0008] According to this utility model, a light-mapping area of transparent material is embedded above or below each scale line on the outer surface of the measuring ruler body to facilitate the display of the light of the LED cursor.
[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: by replacing the existing mechanical stroke acquisition component with a built-in LED cursor, the structure is simplified while making it easier to acquire data and improving reading efficiency. Attached Figure Description
[0010] Figure 1 This is a schematic diagram of the LED measuring ruler for the injection stroke of an injection molding machine according to the present invention;
[0011] Among them, 100 is the measuring ruler body, 200 is the LED cursor, and 110 is the light mapping area. Detailed Implementation
[0012] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.
[0013] like Figure 1 As shown in the illustration, this application discloses an LED measuring ruler for injection stroke of an injection molding machine, used in conjunction with the injection mold cavity of the injection molding machine to facilitate the measurement of the injection stroke, i.e., the amount of material injected into the injection mold cavity. The LED measuring ruler for injection stroke includes a measuring ruler body 100 embedded in the surface of the injection mold cavity. The measuring ruler body 100 has a long, hollow structure with graduations on its outer surface and an electrical control component inside. The electrical control component includes an LED cursor 200 whose position changes with the injection stroke. The LED cursor 200 is a thin line with the same thickness as the graduation lines on the outer surface of the measuring ruler body 100. Its light source is projected onto the surface of the measuring ruler body 100, coinciding with the graduation lines, thus allowing the injection stroke count to be read. A slot is formed on the surface of the injection mold cavity to accommodate the measuring ruler body 100. The measuring ruler body 100 is embedded in the slot and then welded in place. The length direction of the measuring ruler body 100 is aligned with the length direction of the injection mold cavity.
[0014] In this embodiment, a displacement sensor is provided inside the measuring ruler body 100 to obtain the injection volume of material in the injection mold cavity of the injection molding machine and transmit the data to the electronic control component. The electronic control component controls the movement of the LED cursor and displays it on the outer surface of the measuring ruler body 100, which can conveniently obtain the injection stroke.
[0015] In this embodiment, a light mapping area 110 of transparent material is embedded above or below each scale line on the outer surface of the measuring ruler body 100. The LED cursor 200 is better mapped to the outer surface of the measuring ruler body 100 through the transparent material, which improves the mapping effect and makes it easier to read the values.
[0016] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any form or substance. It should be noted that those skilled in the art can make various improvements and additions without departing from the present invention, and these improvements and additions should also be considered within the scope of protection of the present invention. Any modifications, alterations, and equivalent changes made by those skilled in the art based on the above-disclosed technical content without departing from the spirit and scope of the present invention are equivalent embodiments of the present invention. Furthermore, any modifications, alterations, and evolutions made to the above embodiments based on the essential technology of the present invention still fall within the scope of the technical solution of the present invention.
