Description

Technical Field

[0001] This utility model relates to the field of injection mold sorting technology, specifically a cooling system for injection molds of POM transmission components. Background Technology

[0002] Polyoxymethylene (POM), a high-performance engineering plastic, is widely used in the manufacture of transmission components such as gears and bearings due to its excellent mechanical strength, wear resistance, and self-lubricating properties. Injection molding is the main processing method for POM transmission components, and its molding quality is directly affected by the mold temperature control.

[0003] A search revealed a utility model patent with Chinese patent publication number CN207859422U, which discloses a cooling system for an injection mold, comprising: a positioning ring, a front cover plate, and an upper mold plate; the positioning ring is located above the front cover plate, and the upper mold plate is located below the front cover plate; the upper mold cooling water inlet is located at one end of the upper mold plate, and the upper mold cooling water outlet is located at the other end of the upper mold plate; the guide pipe is located inside the upper mold plate and the lower mold plate, and the cooling column is connected to the outer wall of the guide pipe through a through-hole connection.

[0004] The aforementioned device cools the mold by using a cooling column. Its cooling principle is to first cool the surrounding materials before it can absorb the heat from the product. However, since the area close to the product is small, cooling takes a relatively long time, leaving room for improvement. Utility Model Content

[0005] The purpose of this invention is to provide a cooling system for injection molds of POM transmission components, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cooling system for injection molds of POM transmission components, comprising a mold body, a through groove inside the mold body located at the bottom of the molding cavity of the mold body, an installation plate slidably inserted inside the through groove, an installation groove on the top outer wall of the installation plate, a cooling assembly installed inside the installation groove, the cooling assembly comprising a plurality of cooling pipes placed inside the installation groove, each of the plurality of cooling pipes having a connector fixedly sleeved at both ends, a plurality of springs fixedly connected to the bottom inner wall of the installation groove, a common installation ring fixedly connected to one top end of each of the plurality of springs, and the installation ring fixedly connected to the bottom outer wall of the plurality of cooling pipes.

[0007] Ensure that the cooling pipes and the forming cavity area of ​​the mold body are large enough so that the heat of the transmission components can be absorbed more quickly, which is beneficial to improving cooling efficiency. Apply pressure to the connector of the nearby blocking post. The pressure is applied to the spring through the cooling pipes and the mounting ring. The spring is compressed by the force, and multiple cooling pipes will enter the interior of the mounting groove. Insert one end of the mounting plate into the through groove. Stop the insertion operation when the abutment plate is in contact with the outer wall of the mold body. Since the cooling pipes cannot move upward due to the restriction of the through groove, the spring remains compressed and the mounting ring squeezes the cooling pipes against the top wall of the through groove, thereby ensuring that the heat can be directly absorbed.

[0008] As a further preferred embodiment of this technical solution, a number of horizontally distributed electric heating tubes are installed inside the mold body, and the number of electric heating tubes is located between the through groove and the forming cavity of the mold body.

[0009] As a further preferred embodiment of this technical solution, a fixing component is installed on the outside of the mounting plate. The fixing component includes two abutment plates fixedly connected to the outer wall of one side of the mounting plate, and the width of the abutment plates is greater than the width of the mounting plate.

[0010] As a further preferred embodiment of this technical solution, four limiting clips are installed on the outer wall of the other side of the mounting plate, and a common blocking post is placed between two opposite limiting clips. One end of the blocking post is outside the mounting plate, and the outer wall of the blocking post is provided with a limiting groove that matches the limiting clip.

[0011] After installation, move the movable end of the blocking post. Due to the limiting effect of the two limit clips, the blocking post can only rotate until its movable end is in contact with the outer wall of the mold body. At this point, the mounting plate can no longer move and will not easily detach from the through groove during use.

[0012] As a further preferred embodiment of this technical solution, each of the two blocking columns is internally threaded with a screw, and one end of each screw is in contact with the outer wall of the mold body.

[0013] As a further preferred embodiment of this technical solution, the middle positions of several cooling pipes are all arranged in an arc shape, and the center of the arc portion coincides with the center of the forming cavity of the mold body.

[0014] As a further preferred embodiment of this technical solution, the mounting plate has an clearance groove inside, and the mold body has a through hole that matches the clearance groove inside.

[0015] This utility model provides a cooling system for injection molds of POM transmission components, which has the following features:

[0016] Beneficial effects:

[0017] (1) By setting up a cooling component, this utility model ensures that the cooling pipe and the forming cavity area of ​​the mold body are large enough, so that the heat of the transmission component can be absorbed more quickly, which is beneficial to improving the cooling efficiency. Pressure is applied to the connector of the nearby blocking column. The pressure is applied to the spring through the cooling pipe and the mounting ring. The spring is compressed by force, and multiple cooling pipes will enter the mounting groove. One end of the mounting plate is inserted into the through groove. When the abutting plate is in contact with the outer wall of the mold body, the insertion operation is stopped. Since the cooling pipe cannot move upward under the restriction of the through groove, the spring remains compressed and the cooling pipe is squeezed against the top wall of the through groove by the mounting ring, thereby ensuring that the heat can be directly absorbed.

[0018] (2) This utility model, by setting a fixing component, allows the movable end of the blocking column to be moved after installation. Due to the limiting effect of the two limit clips, the blocking column can only be rotated until its movable end is in contact with the outer wall of the mold body. At this point, the mounting plate cannot move further and will not easily detach from the through groove during use. Attached Figure Description

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] This utility model provides a technical solution: such as Figure 2 and Figure 3As shown in this embodiment, a cooling system for a POM transmission component injection mold includes a mold body 1. A through groove 2 is provided inside the mold body 1. The through groove 2 is located at the bottom of the molding cavity of the mold body 1. An installation plate 3 is slidably inserted inside the through groove 2. An installation groove 401 is provided on the top outer wall of the installation plate 3. A cooling component 4 is installed inside the installation groove 401. The cooling component 4 includes a plurality of cooling pipes 402 placed inside the installation groove 401. A connector 403 is fixedly sleeved at both ends of the plurality of cooling pipes 402. A plurality of springs 405 are fixedly connected to the bottom inner wall of the installation groove 401. The same installation ring 404 is fixedly connected to one end of the top of the plurality of springs 405. The installation ring 404 is fixedly connected to the bottom outer wall of the plurality of cooling pipes 402.

[0026] Pressure is applied to the connector 403 of the nearby blocking post 503. The pressure is applied to the spring 405 through the cooling pipe 402 and the mounting ring 404. The spring 405 is compressed by the force, and multiple cooling pipes 402 will enter the interior of the mounting groove 401. One end of the mounting plate 3 is inserted into the through groove 2. The insertion operation is stopped when the abutment plate 501 is in contact with the outer wall of the mold body 1. Since the cooling pipes 402 cannot move upward due to the restriction of the through groove 2, the spring 405 remains compressed and the cooling pipes 402 are pressed against the top wall of the through groove 2 by the mounting ring 404, thereby ensuring that the heat can be directly absorbed.

[0027] like Figure 1 As shown, several horizontally distributed heating tubes are installed inside the mold body 1, and these heating tubes are located between the through groove 2 and the forming cavity of the mold body 1.

[0028] like Figure 2 and Figure 3 As shown, a fixing component 5 is installed on the outside of the mounting plate 3. The fixing component 5 includes two abutment plates 501 fixedly connected to the outer wall of one side of the mounting plate 3, and the width of the abutment plates 501 is greater than the width of the mounting plate 3.

[0029] Four limit cards 502 are installed on the outer wall of the other side of the mounting plate 3. A blocking post 503 is placed between two opposite limit cards 502. One end of the blocking post 503 is outside the mounting plate 3, and the outer wall of the blocking post 503 is provided with a limiting groove that is compatible with the limit card 502.

[0030] After installation, move the movable end of the blocking post 503. Due to the limiting effect of the two limit clips 502, the blocking post 503 can only rotate until its movable end is in contact with the outer wall of the mold body 1. At this time, the mounting plate 3 can no longer move and will not easily detach from the through groove 2 during use.

[0031] like Figure 4As shown, each of the two blocking posts 503 is internally threaded with a screw 504. One end of each screw 504 is in contact with the outer wall of the mold body 1. Rotating the knob of the screw 504 causes the screw 504 to move towards the mounting plate 3 and press against the outer wall of the mold body 1. Under the action of friction, the position of the blocking post 503 will not change arbitrarily.

[0032] like Figure 2 As shown, the middle positions of several cooling pipes 402 are all arranged in an arc shape, and the center of the arc part coincides with the center of the forming cavity of the mold body 1, which ensures the cooling area without having to set too many cooling pipes 402.

[0033] like Figure 1 and Figure 2 As shown, the mounting plate 3 has an clearance groove 6 inside, and the mold body 1 has a through hole that matches the clearance groove 6 inside. The ejector pin of the ejector structure can act on the product inside the forming groove through the clearance groove 6.

[0034] This utility model provides a cooling system for injection molds of POM transmission components, and its specific working principle is as follows:

[0035] During installation, pressure is applied to the connector 403 of the nearby blocking post 503. This pressure is applied to the spring 405 through the cooling pipe 402 and the mounting ring 404, causing the spring 405 to compress. Multiple cooling pipes 402 then enter the mounting groove 401. One end of the mounting plate 3 is inserted into the through groove 2. The insertion operation stops when the abutment plate 501 is in contact with the outer wall of the mold body 1. Because the cooling pipes 402 cannot move upwards due to the restriction of the through groove 2, the spring 405 remains compressed and, through the mounting ring 404, presses the cooling pipes 402 against the top wall of the through groove 2, thus ensuring that heat can be directly absorbed. After installation, the movable end of the blocking post 503 is moved. Due to the limiting effect of the two limit clips 502, the blocking post 503 can only rotate until its movable end is in contact with the outer wall of the mold body 1. At this point, the mounting plate 3 can no longer move and will not easily detach from the through groove 2 during use. Finally, turn the knob of the screw 504 to move the screw 504 toward the mounting plate 3 and press against the outer wall of the mold body 1. Under the action of friction, the position of the blocking column 503 will not change arbitrarily.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
