Description

Technical Field

[0001] The utility model belongs to the technical field of PIR plate forming, in particular to a PIR plate forming die. Background Art

[0002] PIR material is a new type of cold insulation material product used for cold insulation of low-temperature pipelines. It is suitable for low-temperature pipelines that transport refrigerants in equipment in industries such as petrochemicals, refrigeration, and shipbuilding. It is used as a cold insulation component in bracket and hanger support parts. It has the characteristics of high strength, low thermal conductivity, low water absorption, hydrolysis resistance, non-flammability, and beautiful shape.

[0003] Existing PIR sheet forming processes typically require heating before placing the PIR sheet in a mold. Due to the heating, the PIR sheet is easily stuck in the lower mold after forming, making it difficult for workers to remove it. This can cause the PIR sheet to be pried apart during removal, which can easily cause damage and result in economic losses. Therefore, we have proposed a PIR sheet forming mold. Utility Model Content

[0004] The purpose of the utility model is to provide a PIR sheet forming mold, which is provided with a demoulding component. Specifically, the PIR sheet will press the push plate downward during forming, and the limit rod will squeeze the spring at the same time. Finally, after the forming is completed, the upper mold will reset upward, and the push plate will be pushed out and reset upward under the action of elasticity, so as to quickly push the formed PIR sheet upward, avoid the PIR sheet from being stuck in the lower mold, facilitate the staff to remove the PIR sheet, avoid the use of prying, protect the PIR sheet from damage, and solve the problem that the PIR sheet is easily stuck in the lower mold after forming, making it difficult for the staff to remove it, resulting in the PIR sheet being pried during removal and easily causing damage during the prying process.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The utility model is a PIR plate forming mold, comprising a lower mold, an upper mold is arranged above the lower mold, the top of the lower mold contacts the PIR plate, the four corners of the upper mold are slidably connected to the pillars, the bottoms of the four pillars are fixedly connected to the top of the lower mold, a demoulding component is arranged inside the lower mold, and a splint is arranged on the right side of the lower mold;

[0007] The demoulding assembly includes a push plate, a limit rod is fixedly connected to the bottom center of the push plate, a spring is fixedly connected to the bottom of the limit rod, and the bottom of the spring is fixedly connected to the inner wall of the lower mold. By setting the demoulding assembly, specifically, the PIR sheet will press the push plate downward during molding, and the limit rod will squeeze the spring at the same time. Finally, after the molding is completed, the upper mold is reset upward, and the push plate will be pushed out and reset upward under the action of elasticity, thereby quickly pushing the molded PIR sheet upward to prevent the PIR sheet from being stuck in the lower mold, making it convenient for the staff to remove the PIR sheet, avoiding the use of prying, and protecting the PIR sheet from damage.

[0008] Furthermore, a receiving groove is opened inside the lower mold, and the receiving groove is adapted to the push plate. Stabilizing rods are provided in front and rear of the limiting rod. The tops of the two stabilizing rods are fixedly connected to the bottom of the push plate. The stabilizing rods limit the push plate to prevent the push plate from deflecting, so that the push plate can smoothly enter the receiving groove.

[0009] Furthermore, a positioning frame is fixedly connected to the left side of the lower mold, and a fixing block is fixedly connected to the right side of the clamping plate. A threaded hole is opened inside the fixing block, and a threaded rod is threadedly connected to the inner wall of the threaded hole. By setting the clamping plate, specifically, the heated PIR sheet is placed on the lower mold, and the left side of the PIR sheet is contacted with the positioning frame, and then the handle is turned clockwise to drive the threaded rod to rotate, the fixing block will drive the clamping plate to contact with the PIR sheet, so that the PIR sheet can be positioned and simply fixed, thereby avoiding the deviation of the PIR sheet during the molding process and improving the molding effect.

[0010] Furthermore, a turning handle is fixedly connected to the right side of the threaded rod, and the bottom of the splint contacts two limit plates. The left sides of the two limit plates are fixedly connected to the right side of the lower mold. The right side of the lower mold is fixedly connected to a limit ring. The splint will move on the limit plate during movement, which can play a limiting role, thereby making the splint move in a straight line. At the same time, the limit plate can support the threaded rod through the splint and the fixed block.

[0011] Furthermore, the left side of the threaded rod is rotatably connected to the inner wall of the limiting ring, the left side of the clamping plate contacts the right side of the PIR plate, and the left side of the PIR plate contacts the right side of the positioning bracket. The limiting ring is used to limit the threaded rod to prevent the threaded rod from falling or moving.

[0012] Furthermore, the limit rod is slidably connected to the lower mold, the bottom of the stabilizing rod passes through the receiving groove and extends to the inside of the lower mold, the stabilizing rod is slidably connected to the lower mold, and the limit rod is used to limit the moving distance of the push plate and facilitate pressing the spring.

[0013] The utility model has the following beneficial effects:

[0014] 1. The utility model provides a demoulding assembly. Specifically, when the PIR sheet is being formed, the push plate is pressed downward, and at the same time, the limit rod squeezes the spring. Finally, after the forming is completed, the upper mold is reset upward, and the push plate is pushed upward and reset under the action of elasticity, thereby quickly pushing the formed PIR sheet upward to prevent the PIR sheet from being stuck in the lower mold, making it convenient for the staff to remove the PIR sheet, avoiding the need for prying, and protecting the PIR sheet from damage.

[0015] 2. The utility model provides a clamping plate. Specifically, the heated PIR sheet is placed on the lower mold, and the left side of the PIR sheet is brought into contact with the positioning frame. Then, the handle is turned clockwise to drive the threaded rod to rotate, and the fixing block drives the clamping plate to contact the PIR sheet. The PIR sheet can be positioned and simply fixed, avoiding the deviation of the PIR sheet during the molding process and improving the molding effect.

[0016] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
