Description

Technical Field

[0001] The present application relates to the technical field of pipe fitting injection molding, and in particular to a plastic injection molding machine for pipe fitting processing. Background Art

[0002] Injection molding can only be completed with the help of an injection molding machine and a mold. During the injection molding process, the plastic raw material is first heated to a molten state, and then the molten plastic is injected into the mold cavity under high pressure through the screw or plunger of the injection molding machine. After a period of pressure maintenance and cooling, the plastic solidifies in the mold, and finally the mold is opened to take out the product;

[0003] When the pipe fittings are injection molded, some raw materials may remain after demoulding due to their high viscosity and large volume shrinkage, causing some foreign matter in the raw materials to adhere to the inner wall of the mold, thus affecting the next injection molding process.

[0004] The existing patent document "CN105478383B Mold with cleaning device" discloses an injection mold. Although the injection mold equipment in the above technical solution can be used for injection molding, a brush is used to clean the inner wall of the mold. When encountering relatively firm adhering foreign matter, the above cleaning method is prone to incomplete cleaning and residue. At the same time, if a rigid cleaning tool is used, it is easy to collide with the inner wall of the mold when cleaning the inner wall of the mold, resulting in wear and scratches, which in turn causes the inner wall of the mold to be uneven, and it is more likely to cause adhesion problems later.

[0048] See also Figure 1As shown, a plastic injection molding machine for pipe processing, the plastic injection molding machine for pipe processing comprises:

[0049] A plastic injection machine 1, wherein the plastic injection machine 1 is fixedly arranged on the upper surface of the supporting base plate 2;

[0050] A pipe fitting mold 3, wherein the pipe fitting mold 3 is fixedly mounted on the upper surface of the supporting base plate 2, and the injection end of the plastic injection machine 1 is connected to the pipe fitting mold 3;

[0051] A cleaning structure 6, wherein a cleaning tool 7 is fixedly connected to the side of the cleaning structure 6, and the cleaning structure 6 can reciprocate up and down so that the cleaning tool 7 cleans the inner wall of the pipe fitting mold 3;

[0052] A warning component 9, wherein the warning component 9 is connected to the cleaning structure 6, and the warning component 9 can give a warning after the cleaning structure 6 contacts a foreign object;

[0053] The auxiliary cleaning component 8 is connected to the cleaning structure 6, and the auxiliary cleaning component 8 can automatically perform spray cooling after the cleaning structure 6 contacts foreign matter.

[0054] Through the above technical scheme, in order to solve the problem in the prior art that ordinary injection molding machines are prone to mold sticking when processing pipe fittings with high viscosity or large volume shrinkage, resulting in residual raw materials on the inner wall of the mold after demolding, the present application designs a cleaning structure 6, which can clean the inner wall of the mold after demolding, so that the residual raw materials can be effectively separated. Further, in order to solve the problem in the prior art that ordinary cleaning methods are difficult to fully clean relatively firm attachments or easily damage the inner wall of the mold, the present application designs a cleaning tool 7. Through the coordinated use of the cleaning structure 6 and the cleaning tool 7, while cleaning the inner wall of the mold, warning treatment is performed on relatively firm foreign objects, and the auxiliary cleaning component 8 is automatically triggered to further assist in cleaning relatively firm attachments, thereby effectively avoiding the problem that ordinary cleaning equipment cannot completely clean attachments, and at the same time, the inner wall of the mold can be effectively protected during cleaning, avoiding scratches and wear caused by the use of hard and rigid cleaning tools, which is particularly suitable for use on pipe fitting molds.

[0055] For further technical solutions, see Figure 3As shown, a fixed support frame 4 is fixedly connected to the upper surface of the support base plate 2, a lifting component 5 is fixedly installed at one end of the fixed support frame 4, a cleaning structure 6 is fixedly connected to the bottom end of the lifting component 5, and the lifting component 5 is an electric push rod. Through this technical solution, the lifting component 5 can drive the cleaning structure 6 to move up and down reciprocatingly through the extension and contraction of the lifting component 5, thereby driving the cleaning tool 7 to move up and down reciprocatingly, so that the cleaning tool 7 moves along the inner wall of the pipe fitting mold 3, so that the inner wall of the pipe fitting mold 3 can be cleaned and the raw material foreign matter adhering to the inner wall of the pipe fitting mold 3 can be cleaned.

[0056] For specific technical solutions, please refer to Figure 2 and Figure 4 As shown, the cleaning tool 7 includes a thin plate 701 and a rubber outer skin 702. The outer surface of the thin plate 701 is fixedly covered with the rubber outer skin 702. Through the technical solution, through the design of the rubber outer skin 702, the cleaning tool 7 can have a certain degree of softness, thereby protecting the inner wall of the mold. Through the design of the thin plate 701, the cleaning tool 7 has corresponding strength. When cleaning the inner wall of the pipe fitting mold 3, when contacting foreign matter in the raw material, it has sufficient strength to scrape off the foreign matter for cleaning. Compared with soft cleaning tools such as brushes, it has a stronger cleaning effect, effectively avoiding the problem of foreign matter firmly attached being difficult to clean. Compared with hard and rigid cleaning tools, it has a better protection function, avoiding scratching and wearing the inner wall of the mold.

[0057] There are at least two cleaning tools 7, and the edges of the whole formed by the cleaning tools 7 match the inner wall contour of the pipe fitting mold 3. Through this technical solution, the whole formed by the cleaning tools 7 can effectively slide on the inner wall of the pipe fitting mold 3, so as to clean the inner wall of the pipe fitting mold 3, and the design of multiple cleaning tools 7 can be used to assist in cleaning the corresponding areas more specifically when the auxiliary cleaning component 8 and the warning component 9 are triggered later, so as to further improve the cleaning effect.

[0058] As a preferred technical solution, please refer to Figure 5 and Figure 6As shown, the cleaning structure 6 includes a fixed plate frame 601, a tripod 602, a rotating block 603, a fixed cylinder 604 and a reset spring 606, the side wall of the fixed plate frame 601 is fixedly connected with the tripod 602, the rotating block 603 is rotatably connected to the tripod 602, the front end of the rotating block 603 is fixedly connected with a cleaning tool 7, the side wall of the tripod 602 is fixedly connected with the fixed cylinder 604, the side wall of the rotating block 603 is fixedly connected with a rotating shaft 605, one end of the rotating shaft 605 extends into the inner cavity of the fixed cylinder 604 and is rotatably connected to the fixed cylinder 604, one end of a plurality of reset springs 606 is fixedly arranged on the arc-shaped wall of the rotating shaft 605, and the other ends of the plurality of reset springs 606 are fixedly connected to the inner wall of the fixed cylinder 604. Through the present technical solution, the cleaning tool 7 of the present application can be effectively removed. The cleaning tool 7 has a flipping function. When the cleaning tool 7 moves along the inner wall of the pipe fitting mold 3, when encountering foreign matter with insufficient adhesion, the foreign matter can be directly cleaned and scraped off by scraping the cleaning tool 7. When encountering foreign matter with strong adhesion, the scraping of the cleaning tool 7 is not enough to clean the foreign matter, and the foreign matter will squeeze the front end of the cleaning tool 7, causing the cleaning tool 7 to flip. By flipping the cleaning tool 7, the cleaning tool 7 passes over the foreign matter, thereby avoiding direct collision with firm foreign matter, thereby further avoiding vibration caused by collision, thereby avoiding the cleaning tool from scratching and wearing the inner wall of the mold. The design of the present technical solution avoids rigid contact and collision with foreign matter when cleaning foreign matter with strong adhesion, thereby protecting the inner wall of the mold and avoiding the problem that rigid contact cleaning easily damages the inner wall of the mold.

[0059] For further technical solutions, see Figure 7As shown, the interior of the fixed plate frame 601 is provided with an inner cavity, and a guide slider 611 is slidably connected in the inner cavity of the fixed plate frame 601, and one end of a connecting rod 610 is rotatably connected at the side wall of the guide slider 611, and the other end of the connecting rod 610 is rotatably connected to the bottom surface of the cleaning tool 7, and one end of a fixing rod 612 is fixedly connected to the upper surface of the guide slider 611, and the other end of the fixing rod 612 extends into the inner cavity of a connecting sleeve rod 613, and a limiting slider 614 is slidably connected in the inner cavity of the connecting sleeve rod 613, and the fixing rod 61 2 is fixedly connected to the bottom surface of the limit slider 614, the upper end of the connecting sleeve rod 613 is fixedly connected to the output control part 607, one end of the output control part 607 is connected to the auxiliary cleaning component 8, and the other end of the output control part 607 is connected to the nozzle 609, and the nozzle 609 is fixedly arranged at the front end of the connecting frame 608, and the connecting frame 608 is fixedly arranged at the side wall of the fixed plate frame 601. Through the technical solution, when the cleaning tool 7 moves back and forth for cleaning, it can automatically perform auxiliary cleaning and auxiliary cooling when encountering foreign objects that cannot be cleaned. When the cleaning structure 6 moves downward, it drives the cleaning tool 7 to move downward, so that the cleaning tool 7 moves downward along the inner wall of the pipe fitting mold 3, thereby cleaning the inner wall of the pipe fitting mold 3 once. When the lifting component 5 contracts, it drives the cleaning structure 6 to move upward, thereby driving the cleaning tool 7 to move upward, and performing a secondary cleaning on the inner wall of the pipe fitting mold 3. During the secondary cleaning, if there are still foreign objects that are firmly attached and cannot be cleaned, the front end of the cleaning tool 7 will contact the foreign objects, causing the cleaning tool 7 to flip downward. The downward flipping of the cleaning tool 7 can push one end of the connecting rod 610 to move, thereby causing the bottom end of the connecting rod 610 to move downward, and then the downward movement of the connecting rod 610 drives the guide slider 611 to move upward. Move downward, so that the downward movement of the guide slider 611 drives the fixed rod 612 to move downward, thereby driving the connecting sleeve rod 613 to move downward, and the downward movement of the connecting sleeve rod 613 can trigger the output control unit 607 to open, so that the auxiliary cleaning component 8 outputs high-pressure gas, and further the high-pressure gas is sprayed out through the nozzle 609, so that the attached raw material foreign matter can be cleaned, and the high-pressure gas can effectively cool the raw material foreign matter, so that the raw material can be further fully solidified and easy to fall off, and at the same time, the high-pressure air blowing further loosens the foreign matter, thereby achieving the role of auxiliary cleaning, which is particularly suitable for cleaning foreign matter on the inner wall of the mold, and will not damage the inner wall of the mold.

[0060] As a preferred technical solution, please refer to Figure 8 and Fig. 9As shown, the output control unit 607 includes a fixed seat 6071, a connector 6072, an inner cavity 6073, a plug plate 6074 and a through-port 6075. The fixed seat 6071 is fixedly arranged in the inner cavity of the fixed plate frame 601. The two ends of the fixed seat 6071 are fixedly connected with connectors 6072. The inner cavity 6073 is provided with an inner cavity 6073. The connector 6072 and the inner cavity 6073 are communicated with each other. The inner cavity 6073 is slidably connected with a plug plate 6074. The plug plate 6074 is provided with a through-port 6075. The bottom end of the plug plate 6074 is fixedly connected to the upper end of the connecting sleeve rod 613. One of the connectors 6072 is connected to the auxiliary cleaning component. 8, and the other is that the connecting head 6072 is connected to the nozzle 609 through a hose. Through the technical solution, when the cleaning tool 7 moves upward for cleaning, if it encounters a relatively firm foreign object, the foreign object will cause the cleaning tool 7 to flip downward, thereby driving the guide slider 611 to move downward through the downward flipping of the cleaning tool 7, thereby driving the fixing rod 612 and the connecting sleeve rod 613 to move downward through the downward movement of the guide slider 611, and then driving the plug plate 6074 to move downward, thereby the downward movement of the plug plate 6074 can make the through port 6075 move downward, and the through port 6075 moves down to the connecting head 6072, so that the connecting heads 6072 at both ends can be connected, and then the The high-pressure gas generated by the auxiliary cleaning component 8 is delivered to the nozzle 609 through the output control unit 607, so that the nozzle 609 can automatically spray high-pressure gas when the cleaning tool 7 touches the foreign matter. When the cleaning tool 7 passes over the foreign matter, the cleaning tool 7 is reset due to the setting of the reset spring 606, so that the guide slider 611 moves upward, thereby driving the fixing rod 612 and the connecting sleeve rod 613 to move upward, and then pushing the plug plate 6074 to move upward in the inner cavity 6073, so that the through port 6075 moves upward, so that the plug plate 6074 closes the inner cavity 6073, and the function of automatically closing the jet is realized. It can be seen from the above description that the cleaning structure 6 of the present application has the function of automatically targeting the foreign matter part. The jet-assisted cleaning function can automatically release high-pressure gas within a corresponding range when encountering solid raw material foreign matter that is difficult to clean. The high-pressure gas is sprayed on the foreign matter, which can, on the one hand, play a role in loosening the foreign matter and assist in cleaning. On the other hand, the high-pressure sprayed gas can achieve further cooling and temperature reduction function, thereby avoiding the problem of high viscosity and difficulty in cleaning due to insufficient cooling of the raw materials. Compared with ordinary jet cleaning equipment, the present application cooperates with the use of cleaning structure 6 and cleaning tool 7 to spray the parts where foreign matter is attached in a targeted manner, so that the impact energy generated by the high-pressure gas can be fully released at the foreign matter attachment part, avoiding the waste caused by large-area spraying and improving the cleaning efficiency.

[0061] For specific technical solutions, please refer to Fig.10As shown, the auxiliary cleaning component 8 includes an air pump 801, a pipeline 802, a No. 1 pressure bottle 803, a No. 2 pressure bottle 804, an output air pipe 805, a connecting pipe 806 and a one-way valve 807. The output end of the air pump 801 is fixedly connected to one end of the pipeline 802, and the other end of the pipeline 802 is connected to the No. 1 pressure bottle 803. The No. 1 pressure bottle 803 is fixedly connected to one end of the connecting pipe 806, and the other end of the connecting pipe 806 is fixedly connected to the inner cavity of the No. 2 pressure bottle 804. A one-way valve 807 is installed on the pipe 806, and one end of the output air pipe 805 is fixedly connected to the inner cavity of the No. 2 pressure bottle 804, and the other end of the output air pipe 805 extends to one end of the connector 6072 and is fixedly connected to the connector 6072. According to the technical solution, the inner cavity of the No. 1 pressure bottle 803 can be filled with high-pressure gas through the operation of the air pump 801, and the No. 1 pressure bottle 803 and the No. 2 pressure bottle 804 are connected by the connecting pipe 806. When the inner cavity of the No. 1 pressure bottle 803 is filled with high-pressure gas, the No. 1 pressure bottle 803 is connected with the No. 2 pressure bottle 804 by the connecting pipe 806. After the high-pressure gas enters, the high-pressure gas can enter the inner cavity of the No. 2 pressure bottle 804 through the one-way valve 807, so that the inner cavity of the No. 2 pressure bottle 804 is filled with high-pressure gas, and the one-way valve 807 prevents the gas in the inner cavity of the No. 2 pressure bottle 804 from entering the inner cavity of the No. 1 pressure bottle 803. When the output control unit 607 is triggered to open, the high-pressure gas in the inner cavity of the No. 2 pressure bottle 804 is quickly released through the output air pipe 805. After the release is completed, the inner cavity of the No. 2 pressure bottle 804 is filled with high-pressure gas, and then the No. 1 pressure bottle is filled with high-pressure gas. The high-pressure gas in the inner cavity of 803 will enter the inner cavity of the No. 2 pressure bottle 804 through the connecting pipe 806 again, realizing the function of automatically replenishing the high-pressure gas into the inner cavity of the No. 2 pressure bottle 804. When the high-pressure gas in the inner cavity of the No. 1 pressure bottle 803 is gradually consumed, it can be refilled and replenished through the air pump 801. Through this technical solution, the function of automatic output of high-pressure gas can be realized, and at the same time, the high-pressure gas can be automatically replenished after each release. It is easy to use and convenient for jet-assisted cleaning of the inner wall of the pipe fitting mold.
