Description

Technical Field

[0001] This utility model relates to the field of vacuum forming equipment technology, and in particular to a vacuum forming machine processing mold. Background Technology

[0002] Vacuum forming is a process in which a flat sheet of rigid plastic is heated until it softens, then vacuum-adhered to the surface of a mold, and finally cooled to form the desired shape. It is widely used in industries such as plastic packaging, lighting, advertising, and decoration. In the actual vacuum forming process, after the vacuum-formed product cools and sets, due to the physical properties of thermal expansion and contraction of plastic materials, the finished product will adhere tightly to the surface of the mold processed by the vacuum forming machine.

[0003] However, the existing molds used in vacuum forming machines have relatively simple structures and lack sophisticated automated demolding mechanisms. As a result, after processing, operators need to use tools or their bare hands to demold the vacuum-formed products from the molds. This manual operation is not only labor-intensive, but also poses a significant safety hazard because the molds and finished products are still hot after processing, which can easily lead to burns. In addition, manual demolding makes it difficult to ensure even force application, which can easily cause deformation, cracking, and other damage to the vacuum-formed products. This severely restricts the improvement of vacuum forming production efficiency and the stability of product quality.

[0004] Therefore, this utility model proposes a processing mold for a vacuum forming machine to overcome the shortcomings of the prior art. Utility Model Content

This not only results in low work efficiency, but also easily causes safety accidents such as burns to operators when the mold is at high temperature. In addition, uneven force during manual demolding can easily cause deformation and damage to the vacuum-formed products. This utility model aims to provide a vacuum forming machine processing mold with an improved structure that can effectively solve the above problems.

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0031] Example:

[0032] Please refer to Figures 1 to 8 This utility model provides a mold for processing a vacuum forming machine, which aims to solve the structural defects in the prior art, such as low efficiency and insufficient safety due to the reliance on manual operation for the demolding step of the vacuum forming machine mold, and cumbersome operation and poor clamping stability when changing and fixing the mold.

[0033] Please refer to Figure 2 , Figure 3 and Figure 4 The vacuum forming machine processing mold includes a body 1 and a fixing plate 209 fixedly connected to the top of the inner wall of the body 1. The bottom wall of the fixing plate 209 is fixedly connected to the bottom of the inner wall of the body 1. The body 1 serves as the basic support component of the overall device and is used to install the internal demolding mechanism 2 and external auxiliary components. In order to achieve overall adjustment of the mold position, a hydraulic rod 4 is fixedly connected to the upper part of the inner wall of the body 1. A fixing block 5 is fixedly connected to the output end of the hydraulic rod 4. The fixing block 5 can move back and forth with the hydraulic rod 4. A clamping mechanism 3 for fixing the workpiece is provided on the rear side of the outer wall of the fixing block 5. The extension and retraction of the hydraulic rod 4 can drive the fixing block 5 and the clamping mechanism 3 to move back and forth as a whole, thereby adapting to the needs of different processing depths.

[0034] Please refer to Figure 6 , Figure 7 and Figure 8The demolding mechanism 2 is located inside the machine body 1. An electric push rod 201 is fixedly connected to the upper middle part of the inner wall of the machine body 1. A push plate 202 is fixedly connected to the output end of the electric push rod 201. A pad 204 is fixedly connected to the lower middle part of the front side of the outer wall of the push plate 202. A blister pack 207 is fixedly connected to the outer wall of the pad 204. The outer wall of the blister pack 207 is slidably connected to the inner wall of a hole opened in the push plate 206. A push post 205 is fixedly connected to the upper middle part of the outer wall of the push plate 206. Multiple movable rods 208 are fixedly connected at equal intervals on the lower middle part of the front side of the outer wall. The push column 205 and the movable rods 208 are slidably connected to the inner wall of the hole opened in the fixed plate 209. A cover plate 210 is fixedly connected to the upper middle part of the outer wall of the fixed plate 209. A forming mold 211 is installed on the outer wall of the cover plate 210. A push block 203 is rotatably connected to the upper middle part of the front side of the outer wall of the push plate 202. The push block 203 can move and rotate under the drive of the push plate 202, thereby realizing the secondary propulsion action.

[0035] Meanwhile, the clamping mechanism 3 is fixedly connected to the rear side of the outer wall of the fixing block 5. The clamping mechanism 3 includes a mounting base 309 fixedly connected to the rear side of the outer wall of the fixing block 5. A frame 302 is fixedly connected to the rear side of the outer wall of the mounting base 309. An electric push rod 301 is installed on the inner wall of the mounting base 309. The output end of the electric push rod 301 passes through the front side of the outer wall of the frame 302 and is fixedly connected to a slider 303. The front side of the outer wall of the slider 303 is slidably connected to the inner wall of the frame 302. The slider 303 slides left and right on the outer wall. The slide block 303 is dynamically connected to the inner wall of the slide block 304. A slide groove 307 is provided on the rear side of the inner wall of the frame 302. A moving block 305 is fixedly connected to the rear side of the outer wall of the slide block 304. A slide rod 306 is fixedly connected to the top and bottom walls of the moving block 305. The slide rod 306 is slidably connected to the inner wall of the slide groove 307. A clamping block 308 is fixedly connected to the rear side of the outer wall of the moving block 305. The slider 303 is driven to move by the electric push rod 301. With the linkage between the slide block 304 and the moving block 305, the opening and closing movement of the clamping block 308 is realized.

[0036] In a preferred embodiment, in order to achieve secondary acceleration ejection of the second pusher plate 206 at the end of its stroke to ensure complete demolding, a protrusion is fixedly connected to the upper middle part of the rear side of the outer wall of the fixed plate 209. The pusher block 203 is located at the position when the first pusher plate 202 travels to the rear side of the outer wall of the fixed plate 209. The top wall of the pusher block 203 is set at the position that abuts against the protrusion. When the pusher block 203 moves forward with the first pusher plate 202 and contacts the protrusion of the fixed plate 209, the pusher block 203 is obstructed and rotates. The bottom of the outer wall of the pusher block 203 rotates forward and pushes the second pusher plate 206, so that the second pusher plate 206 can continue to move forward relative to the first pusher plate 202.

[0037] In another preferred embodiment, in order to convert the longitudinal thrust of the electric push rod 301 into the lateral clamping force of the clamping block 308, the inner wall of the slide block 304 is provided with an inclined structure that cooperates with the slider 303. When the slider 303 moves back and forth in the frame 302, the inclined structure squeezes or pulls the slide block 304, driving the slide block 304 to move the moving block 305 left and right along the length direction of the slide groove 307. At least two clamping blocks 308 are provided, and the clamping blocks 308 are symmetrically distributed along the length direction of the slide groove 307, thereby realizing the synchronous centering and clamping of the mold or workpiece.

[0038] In another preferred embodiment, in order to ensure the smooth ejection of the molding mold 211, the cover plate 210 is provided with a through hole for the pusher 205 and the pusher plate 206 to pass through. The molding mold 211 is located in front of the through hole. During demolding, the pusher 205 can pass through the cover plate 210 and directly act on the molding mold 211 to eject it.

[0039] Working principle: When using a vacuum forming mold for demolding, the electric push rod 201 is activated to push the push plate 202 forward. The push plate 202 moves the pad 204 and the vacuum forming opening 207. The pad 204 pushes the push plate 206, causing the push column 205 and the moving rod 208 to slide within the hole of the fixed plate 209. When the push plate 206 is stopped at the rear side of the outer wall of the fixed plate 209, the top wall of the push block 203 abuts against the protrusion on the rear side of the outer wall of the fixed plate 209. The push block 203 rotates on the push plate 202 under force. The bottom of the outer wall of the push block 203 swings forward and forcefully pushes the push plate 206 to continue through the hole of the cover plate 210. At the same time, the push column 205 passes through the fixed plate 209 and pushes the forming mold 211, causing the forming mold 211 to detach from the fixed plate 209 and the cover plate 210, pushing away the adhered finished product and achieving automatic demolding.

[0040] When using a vacuum forming mold for clamping, the hydraulic rod 4 drives the fixing block 5 and the clamping mechanism 3 to adjust to the appropriate position. The electric push rod 301 pushes the slider 303 to move within the frame 302. The slider 303 acts on the slide block 304 through the inclined structure, converting the forward and backward linear motion into left and right opening and closing motion, driving the moving block 305 to slide within the slide groove 307, thereby changing the distance between the clamping blocks 308 and achieving firm clamping or release of the fixed object.
