Description

Technical Field

[0001] This invention relates to the field of cooling mechanism technology, and in particular to a high-efficiency cooling mechanism for a high-precision vertical injection molding machine. Background Technology

[0002] Injection molding machines, also known as injection molding machines or injection machines, are the main molding equipment for making various shapes of plastic products from thermoplastic or thermosetting plastics using plastic molds. They are divided into vertical, horizontal, and all-electric types. Injection molding machines can heat plastics and apply high pressure to molten plastics, causing them to be injected and fill the mold cavity.

[0003] The existing patent document with publication number CN215943517U discloses an automated vertical injection molding machine for precision mechanical engineering that can improve work efficiency. The specification discloses that "in use, the movable plate can be pushed by the operation of the telescopic cylinder, and the movable plate can push the lower mold upward. The lower mold can close with the upper mold by moving upward. The injection raw material enters the heating box through the feed hopper. The raw material can melt rapidly in the heating box. After being pressurized by the pressure cylinder, the raw material is sprayed into the upper mold and the lower mold. The water pump and the semiconductor cooler are turned on. The operation of the water pump can draw the cooling medium in the cooling water tank into the water suction pipe, and then into the drain pipe. The drain pipe enters the cooling chamber. The cooling medium can exchange heat with the lower mold. The cooled medium with heat is discharged through the return water pipe and returns to the cooling water tank, forming a complete loop. The operation of the semiconductor cooler can cool the cooling medium to ensure continuous cooling of the lower mold, accelerate the molding speed of the injection molded parts, and effectively improve the production efficiency of the device." and the content shown in the attached drawings of the scheme.

[0004] The above-mentioned solution mainly uses circulating cooling water to cool the molded product in the mold. An inlet is set on one side of the bottom mold and an outlet is set on the other side. The cooling water is then circulated and stored in a collection tank for reuse. In order to improve cooling efficiency, heat-conducting fins are usually set in the cooling cavity of the bottom mold to better conduct the heat of the molded product to the cooling water, thereby improving the cooling efficiency of the molded product. Under long-term use, scale tends to accumulate on the inner wall of the cooling cavity in the bottom mold, especially on the inner wall of the cooling cavity adjacent to the mold cavity wall. If the accumulated scale is not cleaned in time, the cooling effect of the cooling water on the molded product in the mold cavity will be reduced.

[0005] To address these issues, this invention proposes a high-efficiency cooling mechanism for high-precision vertical injection molding machines. Summary of the Invention

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below. All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present invention.

[0021] Example 1: Please refer to Figures 1-10 A high-precision vertical injection molding machine has an efficient cooling mechanism, including a bottom mold body 1, a mounting base at its bottom, a mold cavity 2 and a guide post 3 at its top; a cooling cavity 6 is also provided in the bottom mold body 1, and a cooling water inlet 4 is provided on one side of the bottom mold body 1. The cooling cavity 6 has a guide slope 61 at the bottom and a model cavity support 62 at the top. Heat-conducting plates 7 are fixedly installed at equal intervals at the bottom and sides of the model cavity support 62. The heat-conducting plates 7 installed at the bottom of the model cavity support 62 are vertically installed, and the heat-conducting plates 7 installed on the sides of the model cavity support 62 are inclined. This design also includes a receiving cavity 8 on one side of the bottom mold body 1, which is connected to the coolant outlet 9; a cooling auxiliary mechanism is also provided in the cooling cavity 6, which is used to provide auxiliary cooling for the model cavity 2.

[0022] According to the appendix Figure 1-6 As shown, the cooling of the model cavity 2 in this scheme is mainly achieved by cooling water entering the cooling cavity 6 through the cooling water inlet 4 on one side of the bottom mold body 1. This cooling water works in conjunction with the heat-conducting plates 7 set at the bottom and sides of the cavity support 62 to cool the model cavity 2. Afterward, the cooling water flows out from the coolant outlet 9, thus providing a circulating cooling effect.

[0023] Based on this, this solution also provides auxiliary cooling mechanisms to assist the cooling process. Specifically, the first scraper 1005 scrapes away and cleans impurities accumulated on the bottom of the model cavity support 62 and the heat-conducting plates 7 located at the bottom; the second scraper 1007 scrapes away and cleans impurities accumulated on the sides of the model cavity support 62 and the heat-conducting plates 7 located on the sides. By cleaning the impurities adhering to the heat-conducting plates 7 and the model cavity support 62, the cooling efficiency is ensured, and the cooling effect is prevented from deteriorating. In addition, this solution also uses auxiliary components to clean the impurities left on the first scraper 1005 and the second scraper 1007, ensuring the effectiveness of both scrapers in cleaning impurities.

[0024] Cooling water is introduced into the cooling chamber 6 through the cooling water inlet 4, and then cools the mold cavity support 62 in the cooling chamber 6, thereby cooling the mold cavity 2 and the molded product therein. After that, the cooling water flows out from the cooling water outlet 9. During this process, the heat-conducting plates 7 set at the bottom and sides of the mold cavity support 62 conduct heat from the mold cavity 2 and the molded product to the cooling water, which has an auxiliary effect on the cooling work.

[0025] However, during prolonged operation, impurities will accumulate on the mold cavity support 62 and the heat-conducting plate 7, which will affect the cooling of the mold cavity 2 and the molded product.

[0026] Therefore, combined with the appendix Figure 5 -Appendix Figure 8 As shown, this solution uses a cooling auxiliary mechanism to clean impurities adhering to the mold cavity support 62 and the heat-conducting plate 7, thereby ensuring the cooling effect on the mold cavity 2 and the molded product.

[0027] The cooling auxiliary mechanism includes a mounting slot 1001 located at the opening of one side of the cooling cavity 6; a sealing loading plate 1002 is fitted into the mounting slot 1001 and fixed with screws; a telescopic control cylinder 1003 is installed in the sealing loading plate 1002, and a support crossbar 1004 is fixedly connected to one end of the telescopic control cylinder 1003; a first partition cavity is formed between adjacent heat-conducting plates 7 at the bottom of the model cavity support 62, and a second partition cavity is formed between adjacent heat-conducting plates 7 on the side of the model cavity support 62. First scrapers 1005 are fixedly installed at equal intervals on the top of the support crossbar 1004; the first scrapers 1005 correspond to the positions of the first partition cavities and are installed in the same number of sets.

[0028] Here, a first scraper 1005 is provided at the top of the support crossbar 1004 to clean the bottom of the model cavity support 62 and the heat-conducting plate 7 located at the bottom. Specifically, the telescopic control cylinder 1003 pushes the support crossbar 1004 forward, and the first scraper 1005 located at the top of the support crossbar 1004 enters the first spacer cavity of the adjacent heat-conducting plate 7. During this process, the two sides of the first scraper 1005 contact the side wall of the heat-conducting plate 7 to scrape off impurities on the heat-conducting plate 7; the top of the first scraper 1005 contacts the bottom of the model cavity support 62 to scrape off the impurities adhering to it.

[0029] Vertical support rods 1006 are fixedly installed at both ends of the support crossbar 1004; second scraper blades 1007 are fixedly installed at equal intervals on the inner side of the vertical support rods 1006; the second scraper blades 1007 are inclined and correspond to the position of the second partition cavity and have the same number of sets; the second scraper blades 1007 provide a scraping and cleaning effect for the impurities accumulated on the side of the model cavity support 62 and the heat-conducting plates 7 installed on the side.

[0030] That is, while the telescopic control cylinder 1003 pushes the first scraper 1005, it also pushes the second scraper 1007 to move. The second scraper 1007 enters the second spacer cavity between the adjacent heat-conducting plates 7 on the side of the model cavity support 62. The two sides of the second scraper 1007 clean the impurities on the side wall of the heat-conducting plate 7, and the end of the second scraper 1007 provides a scraping and cleaning of the impurities on the side of the model cavity support 62.

[0031] From the appendix Figure 3 As shown, this solution tilts the heat-conducting plate 7 located on the side of the model cavity support 62, and tilts it downwards, so that after the impurities on the heat-conducting plate 7 are scraped off, the impurities can fall off.

[0032] Combined with the appendix Figure 4 As shown, this solution provides a guide slope 61 at the bottom of the cooling chamber 6. The guide slope 61 is positioned higher than the position near the cooling water inlet 4, which is intended to facilitate the discharge of impurities after cleaning.

[0033] That is, after the impurities on the model cavity support 62 and the heat-conducting plate 7 are scraped off by the first scraper 1005 and the second scraper 1007 respectively, some impurities will flow with the flowing cooling water into the receiving cavity 8 and then be discharged from the coolant outlet 9; some will fall onto the guide slope 61. In order to prevent impurities from depositing at the bottom of the cooling cavity 6, the guide slope 61 will also transport the impurities to the receiving cavity 8 under the action of the flowing coolant and then be discharged from the coolant outlet 9; finally, some may adhere to the first scraper 1005 and the second scraper 1007. Some of the impurities adhering to the first scraper 1005 and the second scraper 1007 will also be carried away by the flowing cooling water and discharged from the coolant outlet 9.

[0034] However, for the remaining impurities adhering to the first scraper 1005 and the second scraper 1007, this solution uses an auxiliary component to clean them, so as to avoid the impurities accumulating in the first scraper 1005 and the second scraper 1007 for a long time, which would affect the cleaning function of both.

[0035] Therefore, combined with the appendix Figure 6 -Appendix Figure 7 and appendix Figure 9 -Appendix Figure 10 As shown, the cooling auxiliary mechanism also includes an auxiliary component for providing a cleaning function for the first scraper 1005 and the second scraper 1007.

[0036] The auxiliary components include a fixing seat 1101 fixed to the inner side of the sealing loading plate 1002 by screws. The fixing seat 1101 is fixed to one end of the connecting rod 1102, and a first support bar 1103 is fixed to the other end of the connecting rod 1102. A first bearing bar 1104 is fixed to both ends of the first support bar 1103. A first loading groove 1105 is equidistantly arranged on the outer side of the first bearing bar 1104, and a side scraper cleaning brush 1106 is arranged in the first loading groove 1105. The first loading groove 1105 and the second scraper 1007 are positioned correspondingly and have the same number of sets.

[0037] That is, after the telescopic control cylinder 1003 drags the first scraper 1005 into the first spacer cavity between adjacent heat-conducting plates 7 at the bottom of the model cavity support 62, and the second scraper 1007 into the second spacer cavity between adjacent heat-conducting plates 7 on the side of the model cavity support 62 to scrape off impurities, the telescopic control cylinder 1003 pulls them back to reset. During the pull-back process of the first scraper 1005 and the second scraper 1007, a scraping and cleaning effect is also provided for the heat-conducting plates 7 and the model cavity support 62, until the first scraper 1005 separates from the first spacer cavity and the second scraper 1007 separates from the second spacer cavity. During the pull-back process of the first scraper 1005 and the second scraper 1007, the second scraper 1007 will pass through the first loading groove 1105, and then be cleaned by the side scraper cleaning brush 1106 set in the first loading groove 1105, that is, the remaining impurities on the second scraper 1007 are removed.

[0038] Here, a bottom connecting vertical bar 1201 is fixedly installed at the bottom middle position of the first support bar 1103; a second bearing bar 1202 is fixedly installed at the bottom end of the bottom connecting vertical bar 1201, and a second loading groove 1203 is equidistantly installed at the bottom side of the second bearing bar 1202. The second loading groove 1203 corresponds to the position of the first scraper 1005 and has the same number of sets; a bottom scraper cleaning brush 1204 is installed in the second loading groove 1203, which is used to clean the first scraper 1005; that is, the first scraper 1005 passes through the second loading groove 1203 at the bottom side of the second bearing bar 1202, and then the bottom scraper cleaning brush 1204 installed in the second loading groove 1203 removes the remaining impurities on the first scraper 1005.

[0039] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
