DETAILED DESCRIPTION
[0028] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0029] In the description of the present application, it should be noted that directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of narrating the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of the present application.
[0030] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.
[0031] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.
[0032] One aspect of the present application provides a mold opening and locking stroke detection device, such as Figure 1 , Figure 2 , Figure 5 and Fig. 9 As shown, one preferred embodiment includes a guide rail 1, a magnetic tape 100, a slider 2 and a magnetic scale reader 3. The guide rail 1 can be fixedly installed on the body of the die-casting machine (not shown), the slider 2 can be slidably installed on the guide rail 1, and the matching surface 10 between the slider 2 and the guide rail 1 is an arc surface, and the matching surface 10 of the arc surface can make the force between the slider 2 and the guide rail 1 uniform, thereby ensuring the movement stability of the slider 2. The slider 2 is also matched with the guide rail 1 through the support structure 5, so that during the sliding process of the slider 2, the support structure 5 can limit the freedom of the slider 2 along the circumferential direction to ensure the stability of the slider 2 during the sliding process, thereby improving the detection accuracy in the subsequent long-stroke detection process. The magnetic tape 100 is fixedly installed on the guide rail 1, and the magnetic scale reader 3 is fixedly installed on the slider 2. During the sliding process of the slider 2 along the guide rail 1, it can drive the magnetic scale reader 3 to move together, and then detect the mold opening and locking stroke through the position of the magnetic scale reader 3 relative to the magnetic tape 100.
[0033] It should be known that the conventional slider 2 and the guide rail 1 are combined in a rectangular shape, which results in the force on the slider 2 being basically concentrated on the upper end surface of the guide rail 1; if the upper end surface of the guide rail 1 with a rectangular cross-section is not flat, the slider 2 will fluctuate during the sliding process, thereby affecting the accuracy of the mold opening and locking stroke detection; at the same time, the guide rail 1 with a rectangular cross-section and the slider 2 have basically no pressure in the width direction, so that the slider 2 may deviate left and right during the sliding process along the guide rail 1, further affecting the accuracy of the mold opening and locking stroke detection.
[0034] In this embodiment, the matching cross section of the guide rail 1 and the slider 2 can be set to be arc-shaped, that is, the matching surface 10 of the guide rail 1 and the slider 2 is an arc-shaped surface in the circumferential direction. Therefore, the pressure of the slider 2 on the guide rail 1 can be completely concentrated on the axial position of the guide rail 1 along the radial direction of the cross section, which can effectively increase the contact area between the guide rail 1 and the slider 2 to improve the sliding stability of the slider 2 relative to the guide rail 1, thereby improving the accuracy of the mold opening and locking stroke detection, especially in the case of long stroke detection. At the same time, the arc-shaped matching surface 10 can limit the slider 2 in multiple directions to further increase the sliding stability of the slider 2 to improve the accuracy of the mold opening and locking long stroke detection.
[0035] It is understandable that the mating surface 10 can be a non-circular surface or an arc surface. In this embodiment, an arc surface is preferably used. Specifically, the cross-sectional profile of the upper portion of the guide rail 1 is an arc shape, so that the upper surface of the guide rail 1 forms a corresponding mating surface 10; at the same time, the lower portion of the slider 2 is provided with a mounting groove 21 that is slidably matched with the upper portion of the guide rail 1 and has an arc-shaped cross section, so that the inner surface of the mounting groove 21 can also form a corresponding mating surface 10. It should be noted that in order to ensure the support stability and structural strength of the guide rail 1, the central angle corresponding to the arc length of the cross section of the mating surface 10 should be greater than 180° and less than 300°. Greater than 180° is to ensure that the slider 2 can be stably connected to the guide rail 1 without detachment, and less than 300° is to ensure that the remaining thickness of the upper portion of the guide rail 1 can meet the support strength of the overall structure of the slider 2.
[0036] In this embodiment, Figure 4 , Figure 5 , Figure 8 and Fig. 9 As shown, a guide plate 12 is provided at the lower end of the guide rail 1, and the support structure 5 includes at least one pair of guide wheels 52, and the two guide wheels 52 of each pair are symmetrically arranged along the travel direction of the slider 2. When the slider 2 is slidably mounted on the guide rail 1, the guide wheels 52 can contact the guide plate 12 at the lower part of the guide rail 1 and roll along the guide plate 12 as the slider 2 slides. In this way, the freedom of the slider 2 can be limited in the circumferential direction of the guide rail 1 by the two guide wheels 52 of each pair, thereby improving the movement stability of the slider 2, so as to further improve the accuracy of the long stroke detection of the unlocking and locking mold.
[0037] It should be known that there are various matching positions of the guide wheel 52 and the guide plate 12. The guide wheel 52 may be matched with the upper end surface of the guide plate 12, or the guide wheel 52 may be matched with the lower end surface of the guide plate 12. For ease of understanding, the following will be described in detail by combining the number of guide wheels 52 with two specific examples.
[0038] Example 1: Figure 4 and Figure 5As shown, there is a pair of guide wheels 52, and the guide wheels 52 can cooperate with the upper end surface of the guide plate 12. In the process of sliding of the slider 2, the swing freedom of the slider 2 in the circumferential direction is limited by the contact between the two guide wheels 52 and the guide plate 12, thereby stabilizing the sliding trajectory of the slider 2.
[0039] Example 2: Figures 6 to 9 As shown, there are three pairs of guide wheels 52, of which two pairs of guide wheels 52 are installed at the front and rear positions of the slider 2 and cooperate with the upper end surface of the guide plate 12, and the remaining pair of guide wheels 52 are installed in the middle of the slider 2 and cooperate with the lower end surface of the guide plate 12. The two pairs of guide wheels 52 at both ends can form a simply supported beam structure for the slider 2, and the middle guide wheel 52 can restrain each other with the two pairs of guide wheels 52 at both ends, and then the three pairs of guide wheels 52 form a support structure 5 with sufficient support strength and limiting ability, which can effectively improve the stability of the sliding track of the slider 2.
[0040] It can be understood that the above two examples can both meet the requirements of this application, and technicians in this field can make their own selection according to actual needs.
[0041] Specifically, Figure 1 , Figure 4 , Figure 7 and Figure 8 As shown, the mold opening and locking stroke detection device also includes a connecting seat plate 4, and the support structure 5 also includes a support block 51 and a connecting plate 53. The connecting seat plate 4 is detachably fixedly connected to the slider 2, the support block 51 is fixedly connected to the connecting plate 53, and the connecting seat plate 4 is fixedly connected to the connecting plate 53. The guide wheel 52 can be rotatably mounted on the support block 51; the magnetic scale reader 3 can be mounted on the connecting seat plate 4.
[0042] In this embodiment, Figure 1 and Figure 7 As shown, the slider 2 is connected to the die-casting machine's clamping mechanism via a vertically fixed support rod 300 , so that the slider 2 is driven to slide along the guide rail 1 through the mold opening and locking actions of the clamping mechanism.
[0043] Specifically, Figure 1 , Figure 3 , Figure 6 and Figure 7 As shown, a U-shaped hole 41 is further provided at the center of the connecting seat plate 4, and a pressing plate 200 is further connected to the upper end of the connecting seat plate 4, and the pressing plate 200 is L-shaped. The lower end of the pressing plate 200 is installed with the connecting seat plate 4 by fasteners and the U-shaped hole 41, and fixedly connected; the support rod 300 can be fixedly connected with the pressing plate 200. By adjusting the relative position of the fastener and the U-shaped hole 41, the relative position of the pressing plate 200 together with the support rod 300 and the connecting seat plate 4 can be adjusted, thereby improving the adaptability of the device.
[0044] In this embodiment, Figure 2 As shown, a groove 11 is formed at the upper end of the guide rail 1, and a magnetic tape 100 is fixedly installed inside the groove 11. During the mold opening and locking stroke detection process, the magnetic scale reader 3 is displaced along with the slider 2. After the displacement, the magnetic scale reader will stay within the scale range of the magnetic tape 100. At this time, the data of the mold opening and locking stroke is read according to the relative position of the magnetic scale reader 3 and the magnetic tape 100.
[0045] It should be known that the magnetic scale reader 3 and the magnetic tape 100 cooperate and measure through the force of the magnetic field, and the specific structure and working principle are well known to those skilled in the art, so they will not be elaborated in detail here.
[0046] Another aspect of the present application provides a die-casting machine, in which a preferred embodiment includes the above-mentioned mold opening and locking stroke detection device, which can be installed on the body of the die-casting machine and perform synchronous action with the mold locking mechanism of the die-casting machine to detect the stroke.
[0047] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application. The present application may have various changes and improvements without departing from the spirit and scope of the present application, and these changes and improvements fall within the scope of the present application for which protection is sought. The scope of protection claimed by the present application is defined by the attached claims and their equivalents.
