[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0025] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.
[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.
[0027] like Figures 1 to 3 The extra-long middle and lower mold lifting device shown in the figure includes: a hydraulic device 1, a support plate 2 and a lifting mechanism 3; the support plate 2 is fixedly connected to the equipment bottom plate 7 through a first fixing plate 4; the hydraulic device 1 is located on one side of the support plate 2, and is fixedly connected to the support plate 2 through two upper and lower fastening plates 5; the lifting mechanism 3 is located on the other side of the support plate 2, and is fixedly connected to the support plate 2 through a slot 21 on the support plate 2; wherein the hydraulic device includes a cylinder 11 and a floating joint 12; the lifting mechanism 3 includes a slide rail 31, a slider 32 and a fixed plate 33, the slide rail 31 fits with the slot 21 of the support plate 2, the slider 32 is connected to the slide rail 31 for sliding up and down, and the fixed plate 33 is fixedly connected to the slider 32.
[0028] The implementation process of the utility model is that the molding material is gradually solidified in the mold located above the device under a certain pressure and temperature, and the mold moves downward through the second fixing plate 6 and the fixing plate 33 connected thereto, and the slider 32 connected to the fixing plate 33 slides downward on the slide rail 32. At this time, the floating joint 12 moves upward under the action of the cylinder 11, and the molding material is ejected from the mold from the center line position of the mold.
[0029] In the present invention, the fastening sheet 5 is fixedly connected to the cylinder 11 by bolts. Since the shape of the fastening sheet 5 is usually flat, a large contact surface can be provided, thereby increasing the friction force and making the cylinder 11 more stably fixed. At the same time, the screwing of the bolts can cause the fastening sheet 5 to produce elastic deformation, further increasing the friction force and improving the stability of the cylinder 11. This stability can not only prevent the cylinder 11 from falling off due to vibration or impact, but also ensure that the cylinder 11 remains in good working condition after long-term operation.
[0030] On the basis of the above, the floating joint 12 and the cylinder 11 are connected up and down, and the end face height of the floating joint 12 is greater than the end face height of the support plate 2. The design of the floating joint 12 and the cylinder 11 being connected up and down can improve the use efficiency of the cylinder 11. The floating joint 12 can move freely within a certain range, so that the working position of the cylinder 11 can be flexibly adjusted according to work needs, so that it can better adapt to the working environment. At the same time, the floating joint 12 can also reduce the friction between the cylinder 11 and the fixed parts, reduce energy loss, and improve the working efficiency of the cylinder 11.
[0031] In order to improve the stability of the slider 32, a first groove is provided on one side of the slider 32, one side of the slide rail 31 is matched with the slot 21 of the support plate 2, and the other side is located in the first groove. Since the first groove of the slider 32 is matched with the slot 21 of the slide rail 31, when the slider 32 slides on the slide rail 31, it will maintain a stable motion trajectory under the restriction of the slot 21, and will not deviate or swing, which greatly improves the operation accuracy and stability.
[0032] In this solution, a second groove is provided on one side of the fixed plate 33, and the other side of the sliding block 32 is matched with the second groove. A second fixing plate 6 is provided at the top of the other side of the fixed plate 33, flush with the end surface. By providing the second groove and the second fixing plate 6, the stability of the combination of the fixed plate 33 and the sliding block 32 can be effectively improved. When the sliding block 32 encounters external force during movement, the second groove can provide a stable support point to prevent the sliding block 32 from deflecting or rotating. At the same time, the second fixing plate 6 can enhance the bearing capacity of the fixed plate 33 and improve the stability of the entire system.
[0033] On the basis of the above, the first fixing plate 4 and the second fixing plate 6 are each provided with a through hole. By providing the through holes on the fixing plates, fasteners such as bolts or screws can be conveniently used for installation, which greatly improves the installation efficiency. At the same time, the through holes can accurately adjust the tightness of the connecting parts, thereby improving the stability of the connection, and can also make the stress of the connecting parts more evenly distributed, thereby reducing stress concentration.
[0034] Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the description are only for explaining the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which are within the scope of the present invention. The scope of protection of the present invention is defined by the attached claims and their equivalents.
