Description

Technical Field

[0001] The utility model relates to the technical field of die repair inserts, in particular to a replaceable screw-connected insert for die repair. Background Art

[0002] Plastic profile extrusion technology is a continuous process in which the material is heated and pressurized by an extruder, then extruded through a die head to form a parison. The parison then undergoes dry and wet shaping, rapid cooling, and solidification. Once the parison enters the shaping chamber, vacuum adsorption allows it to fully contact the walls of the shaping chamber and rapidly solidify, resulting in the profile's outer wall taking on a desired shape.

[0003] In the existing molding extruder, the problem of insufficient mold strength, difficulty in mold repair and affected product appearance quality is improved by adopting the method of fixing and splicing inserts. However, there are still problems such as the inserts cannot be reused, which increases the manufacturing cost. Secondly, it is more troublesome to debug and repair, which affects the mold debugging cycle.

[0004] The problem that the inserts in the above-mentioned prior art cannot be reused can be solved by changing the fixed inserts into replaceable inserts, and installing the replaceable inserts in the mounting grooves on the preformed plates by screws. This allows the inserts to be replaceable, which means that when the inserts are worn, damaged, or need to adapt to different working conditions, they can be replaced quickly and easily without replacing the entire equipment or components, thereby improving the adaptability and flexibility of the equipment or products.

[0005] However, during the use of replaceable inserts, since they are not designed to be integrated with the template, the inserts may be heated unevenly and overheated. Overheating will cause changes in the physical and chemical properties of the insert material, such as a significant decrease in hardness, strength, toughness and other properties, thereby affecting the overall use effect of the insert. Utility Model Content

[0006] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a replaceable screw-connected insert when repairing a mold, which solves the problem that the insert in the prior art cannot be reused.

[0007] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0008] A replaceable screw-in insert for mold repair includes two forming plates, which fit together. A replaceable screw-in insert body is movably connected to the top ends of the two forming plates. The replaceable screw-in insert body is used to enhance the functionality and durability of the forming plates, machine components, and base structure. This allows for easy removal and replacement of the replaceable screw-in insert body.

[0009] As a further improvement of the present invention, the top of each forming plate is fixedly connected to a first connecting block, the top of each connecting block is fixedly connected to a first clamping block, the top side of each forming plate is fixedly connected to a second connecting block, and the side of each connecting block away from the forming plate is fixedly connected to a second clamping block. This ensures that the replaceable screw-in insert body is fixedly secured.

[0010] As a further improvement of the present invention, the side surfaces of the first and second clamping blocks are both provided with a threaded groove, and the tops of the first and second clamping blocks are both provided with a sliding groove, thereby ensuring that the cooling device will not fall off.

[0011] As a further improvement of the present invention, the replaceable screw-in insert body is provided with a second thread groove extending through the portion corresponding to the first thread groove. Screws are threadedly connected to the corresponding side surfaces of the first and second thread grooves, and nuts are threadedly connected to the inserted ends of the screws. This allows the replaceable screw-in insert body to be installed.

[0012] As a further improvement to the present invention, two cooling plates are symmetrically mounted on the tops of the first and second clamping blocks. Sliding blocks are slidably connected to the interiors of the sliding grooves. Four sliding blocks are symmetrically fixedly connected, two by two, to the sides of the two cooling plates facing away from each other. This allows for cooling and collision prevention during use of the replaceable screw-in insert body.

[0013] As a further improvement to the present invention, a plug-in rod is fixedly connected to the side of one cooling plate adjacent to the other cooling plate, a through-hole is formed through the other cooling plate at a position corresponding to the plug-in rod, a fixing slot is formed at the top of the plug-in rod, and a rotating pin is fixedly connected to the side of the cooling plate with the through-hole, away from the plug-in rod, and the outer surface of the rotating pin is rotatably connected to the fixing rod. This ensures that the cooling device will not shift during use of the replaceable screw-in insert body.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. Using the first and second clamping blocks, the replaceable screw-in insert, screws, and nuts, the screws thread the holes in the first clamping block and the second clamping block, and the screws seal the holes in the replaceable screw-in insert. The nuts then seal the screws, securing the replaceable screw-in insert. The threaded connection allows for easy removal and installation. When the replaceable screw-in insert wears or needs replacement, it can be quickly removed and installed, reducing production line downtime and ensuring continuous and efficient production. The simple removal and installation process reduces the complexity and time cost of maintenance. By replacing different replaceable screw-in inserts, the mold can be easily adapted to the production needs of different products, enabling diversified production. If a mold problem arises, the replaceable screw-in insert can be quickly removed to locate the problem, expediting repairs.

[0016] 2. By combining the cooling plate, the plug-in rod, the fixing slot, and the fixing rod, the cooling plate fits together to allow the plug-in rod to pass through the through-hole, which is then secured by the fixing rod. This allows the cooling plate to cool the replaceable screw-in insert while also preventing it from being bumped. The cooling provided by the cooling plate maintains the physical and chemical properties of the replaceable screw-in insert, ensuring stable performance in high-temperature environments and avoiding downtime and maintenance due to overheating. Furthermore, preventing bumps can reduce production interruptions caused by accidental damage, further improving production efficiency. Cooling reduces thermal stress on the replaceable screw-in insert caused by high temperatures, reducing the risk of wear and deformation, thereby extending its service life. Furthermore, preventing bumps can reduce damage to the replaceable screw-in insert from physical impact, further reducing the frequency and cost of replacing the replaceable screw-in insert.

DETAILED DESCRIPTION

[0024] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without violating the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly attached to the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0026] As shown in the figure, a replaceable screw-in insert for mold repair includes a forming plate 101, a clamping block 103, a clamping block 105, a thread groove 106, a replaceable screw-in insert body 201, a screw 202 and a nut 203.

[0027] After the two forming plates 101 are joined together, the operator places the replaceable screw insert body 201 on top of the forming plate 101. The replaceable screw insert body 201 is positioned so that the second thread groove 204 on the top of the replaceable screw insert body 201 aligns with the first thread groove 106 on the first clamping block 103, and the second thread groove 204 on the bottom of the replaceable screw insert body 201 aligns with the first thread groove 106 on the second clamping block 105. Screw 202 is then threaded through the first thread groove 106, the second thread groove 204, and the first thread groove 106, which are all on the same horizontal line. The screw is then tightened with a nut 203 on the exposed end of the replaceable screw insert body 201. This allows for quick removal and installation when the replaceable screw insert body 201 becomes worn or needs to be replaced, shortening production line downtime and ensuring continuous and efficient production. Furthermore, the simple removal and installation process reduces the complexity and time cost of maintenance work.

[0028] Furthermore, after the replaceable screw-in insert body 201 is secured, the cooling plates 205 located at the tops of the first and second clamping blocks 103 and 105 are slid, causing the sliding blocks 206 fixed to the sides of the sliding plates 206 to slide within the sliding grooves 107, thereby controlling the two cooling plates 205 to move closer together. At this point, the plug-in rod 207 fixed to the side of one cooling plate 205 passes through the through-hole 209 of the other cooling plate 205. When the two cooling plates 205 are fully aligned, the cooling plates 205 can cool the replaceable screw-in insert body 201 while also preventing it from colliding. This effective cooling measure ensures that the replaceable screw-in insert body 201 maintains stable performance in high-temperature environments, avoiding downtime and maintenance due to overheating. Furthermore, preventing the replaceable screw-in insert body 201 from colliding can reduce production interruptions caused by accidental damage, thereby further improving production efficiency.

[0029] Furthermore, when the fixing slot 208 formed at the top of the plug-in rod 207 just exposes the cooling plate 205, the fixing rod 210 is then controlled to rotate counterclockwise along the rotating pin 211, thereby locking the fixing rod 210 with the fixing slot 208. When the two cooling plates 205 are tightly fitted and do not separate at the top, the connection between them is more secure, thereby enhancing the strength and stability of the overall structure. In addition, the tight fit can also reduce damage caused by factors such as friction and wear.

[0030] The advantages of this invention are: 1) When the replaceable screw-in insert body 201 becomes worn or needs to be replaced, it can be quickly disassembled and installed, thereby reducing production line downtime. 2) It ensures that the replaceable screw-in insert body 201 maintains stable performance in high-temperature environments, avoiding downtime and maintenance due to overheating. 3) The two cooling plates 205 at the top are tightly fitted together, and the top end prevents slippage, which allows for more efficient heat transfer, reduces the temperature of the replaceable screw-in insert body 201, and improves the stability and lifespan of the equipment.

[0031] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
