Description

Technical Field

[0001] This utility model relates to the field of mold fixing technology, specifically a tooling fixture for fixing molds. Background Technology

[0002] Mold fixing fixtures are key equipment in the field of mechanical manufacturing. They are mainly used to accurately position and reliably clamp molds during processing, inspection or assembly to ensure their stability and processing accuracy.

[0003] The prior art patent document CN219685498U provides a tooling fixture for fixing a mold, including a worktable and a support platform disposed on the top surface of the worktable. Moving components are symmetrically arranged on both sides of the support platform. One end of each moving component is connected to a clamping component. Each moving component includes a fixed end and a connecting head. The clamping component includes a clamping plate, a mounting block, and a mounting groove. A disassembly component is disposed between the mounting block and the mounting groove. The disassembly component includes an internal groove, a pressing block, a pressing groove, and a return spring. The pressing block is slidably connected to the inside of the internal groove via the return spring. By providing a detachable clamping component at one end of the moving component, the clamping component can be replaced according to the shape and size of the mold, providing high flexibility and allowing the tooling fixture to be well-suited for clamping molds of various shapes, thus improving the applicability of the fixture and enabling better use.

[0004] Although the device has many beneficial effects, it still has the following problems: the side wall of the connector is only cushioned by a single spring structure, which is not efficient enough and the fatigue life of the spring is low. Secondly, when replacing the clamping component, the pressure block needs to be pressed simultaneously on both sides, which increases the failure rate of disassembling heavy clamps. Furthermore, the clamp's reset and fixation rely solely on the spring structure, which poses a risk of fixation failure and reset jamming. Utility Model Content

[0005] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0006] 1. Technical problems to be solved:

[0007] To address the issues of insufficient buffering performance and poor unlocking reliability mentioned above, this utility model is proposed.

[0008] Therefore, the purpose of this utility model is to provide a tooling fixture for fixing molds, which is designed with a five-level buffer structure. The buffer structure consists of a main buffer spring, a telescopic guide rod, a conical silicone sleeve, a disc spring one, and a disc spring two, designed on the side wall of the connecting block.

[0033] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0034] This utility model provides an overall structural diagram of an embodiment of a tooling fixture for fixing a mold, including:

[0035] Please see Figures 1-5 This embodiment of a mold fixing fixture includes a base plate 100. A support base 120 is fixedly connected to the top of the base plate 100 by bolts. A buffer assembly 200 is provided on the side wall of the support base 120. The buffer assembly 200 includes a support block 210, a buffer spring 240, a buffer sleeve 250, a disc spring 251, and a disc spring 252. A fixing assembly 300 is provided inside the support block 210. The fixing assembly 300 includes a limiting block 330 and a limiting tooth 340. A clamping assembly 400 is provided on the side wall of the limiting tooth 340. The clamping assembly 400 includes a check bar 411, a spring sheet 420, a check block 430, and a button 440.

[0036] It is worth noting that, specifically, for the purpose of mold fixing and processing, a worktable 110 is welded to the top of the base plate 100. A sliding groove is provided on the top of the worktable 110, and a positioning block 111 is slidably connected to the top of the sliding groove. By moving the positioning block 111 laterally and making the side walls of the two positioning blocks 111 fit tightly against the mold, the mold is initially centered and positioned.

[0037] Next, to buffer vibration and impact during mold fixing, the buffer assembly 200 specifically includes a connecting block 211 for connecting the support base 120. The sidewall of the connecting block 211 is integrally formed to connect the support block 210. The inner cavity sidewall of the support block 210 has a sliding groove 212. Four limiting rods 220 are welded to the inner cavity sidewall of the support block 210 to limit the mounting block 310 and prevent the buffer spring 240 from overloading. Buffer pads 221 are adhered to the sidewalls of the limiting rods 220. The inner cavity sidewall of the support block 210 is fixed... The fixed connection has two guide rods 230, and the end of the guide rod 230 is fixedly connected to the mounting block 310. The inner cavity side wall of the support block 210 is fixedly connected to two buffer springs 240. The guide rod 230 passes through the inside of the buffer spring 240. The outer circumference of the buffer spring 240 is fitted with a buffer sleeve 250, which is made of silicone. Three disc springs 251 are glued to the side wall of the buffer sleeve 250. The support block 210 is glued to the side wall of the disc springs 251. Two disc springs 252 are glued to the other side of the buffer sleeve 250.

[0038] Meanwhile, in order to connect the clamping assembly 400, specifically, the fixing assembly 300 includes a mounting block 310. The side wall of the mounting block 310 is fixedly connected to a disc spring 252. The side wall of the mounting block 310 is integrally formed with two sliders 320. The shape and size of the sliders 320 match the shape and size of the slide groove 212. The side wall of the sliders 320 is slidably connected to the slide groove 212. The side wall of the mounting block 310 has an installation groove to facilitate the insertion and connection of the clamping block 410. The inner side wall of the installation groove is integrally formed with four limiting blocks 330 at the corner for centering the clamping block 410. The inner side wall of the installation groove is integrally formed with multiple limiting teeth 340 for locking the clamping block 410.

[0039] Furthermore, to facilitate mold clamping and fixing, specifically, the clamping assembly 400 includes a clamping block 410, with a check strip 411 integrally formed on the side wall of the clamping block 410, a square groove on the other side wall of the clamping block 410, a spring sheet 420 fixedly connected to the inner side wall of the square groove, a check block 430 welded to the outer side wall of the spring sheet 420, a button 440 fixedly connected to the edge of the outer side wall of the spring sheet 420, and a clamping plate 450 integrally formed on the side wall of the clamping block 410.

[0040] It is worth noting that, in order to improve the cushioning performance of the buffer assembly 200, specifically, the buffer pad 221 has a circular structure, the guide rod 230 has a telescopic structure to facilitate the guidance of the buffer spring 240 when it undergoes elastic deformation, and the buffer sleeve 250 has a conical structure to further improve the cushioning performance of the buffer sleeve 250.

[0041] Finally, to facilitate the connection stability of the clamping block 410, specifically, multiple limiting grooves 412 are provided at the corner of the side wall of the clamping block 410, which are used in conjunction with the limiting block 330 for positioning and to improve connection stability. The side wall of the anti-reverse block 430 and the button 440 penetrates the clamping block 410, which facilitates the locking of the clamping block 410 and the operation of the user. The button 440 has a square structure, and the clamping plate 450 has an arc structure, which facilitates the clamping and fixing of irregular molds.

[0042] In addition, the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0043] Combination Figures 1-5 The specific usage process of the mold fixing fixture of this embodiment is as follows:

[0044] 1: Place the tooling fixture for fixing the mold at the designated location, then place the mold to be processed on the top of the workbench 110, then slide the two positioning blocks 111 to perform preliminary lateral positioning of the mold, and make the clamping plates 450 on both sides clamp and fix the mold on both sides.

[0045] 2: When the clamping block 410 is compressed or vibrates, the impact energy is transmitted through the mounting block 310. Then, the mounting block 310 drives the slider 320 to slide inside the slide groove 212. The buffer spring 240, disc spring 1 251, disc spring 2 252 and buffer sleeve 250 effectively buffer the impact energy through elastic deformation. The limiting rod 220 and the buffer pad 221 limit the displacement distance of the mounting block 310 to avoid damage caused by overload of the elastic deformation of the buffer spring 240.

[0046] 3: When the clamping block 410 and the mounting block 310 are connected normally, the limiting teeth 340 on both sides cooperate with the anti-reverse strip 411 and the anti-reverse block 430 to prevent backflow. When the clamping block 410 needs to be disassembled and replaced, press the button 440 to unlock the anti-reverse block 430, and then the clamping block 410 can be directly removed. When installing a new clamping block 410, it is only necessary to push it in directly. The anti-reverse block 430 and the limiting teeth 340 move autonomously through the inclined plane. After installation, the anti-reverse block 430 is pushed by the spring plate 420 to make it stick tightly to the limiting teeth 340 for anti-reverse fixation.

[0047] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
