Description

Technical Field

[0001] The present application relates to the technical field of silicone injection machines, and in particular to a vertical externally opening mold double-slider liquid silicone injection machine. Background Art

[0002] Silicone products are widely used in life due to their non-toxic characteristics. Liquid silicone thermosetting molding is one of the ways to make silicone products. Liquid silicone has good fluidity and fast vulcanization speed. Silicone products made by using liquid silicone have excellent transparency, tear strength, resilience, and thermal stability.

[0003] In the related art, a vertical injection machine double-slider mold moving mechanism disclosed in a Chinese patent with the publication number CN204431621U has the following technical key points: It includes a first slider, a second slider, a fixed plate, a machine table, a first sliding cylinder, and a second sliding cylinder. The first sliding cylinder and the second sliding cylinder are relatively arranged and fixed on the machine table. The fixed plate is fixed on the machine table. The first slider and the second slider are respectively driven by the first sliding cylinder and the second sliding cylinder to move on the fixed plate.

[0004] In the above device, the upper mold is fixedly installed on the machine table, and the lower mold is fixedly installed on the slider. Since there is only one upper mold, both lower molds correspond to the upper mold, and only one type of silicone product can be produced at the same time. However, in the actual production process, when changing production batches, it is often necessary to produce two types of silicone products at the same time. At this time, the above injection machine cannot meet this requirement, restricting the flexibility and diversity of production. Summary of the Invention

[0005] In order to enable the injection machine to produce two types of silicone products at the same time, the present application provides a vertical externally opening mold double-slider liquid silicone injection machine.

[0006] The vertical externally opening mold double-slider liquid silicone injection machine provided by the present application adopts the following technical solutions: A vertical externally opening mold double-slider liquid silicone injection machine includes a machine table; A mold moving mechanism includes a slider, a first power telescopic member, a first heating plate, and a module. The slider is slidably connected to the machine table along the length direction of the machine table. The first power telescopic member is used to drive the slider to slide. There are two first heating plates, which are fixedly connected to the slider at intervals along the length direction of the machine table. There are two groups of modules, and each module corresponds to a first heating plate; The module includes an upper mold and a lower mold. The lower mold is fixedly connected to the first heating plate. The upper mold is vertically slidably lapped on the lower mold. Injection slots are provided on both sides of the upper mold and the lower mold that are close to each other; An injection mechanism for injecting liquid silicone into a glue injection groove; A mold opening mechanism for driving the upper mold to slide upward and separating the upper mold from the lower mold.

[0007] By adopting the above technical solution, when the module in the injection mechanism injects silicone and undergoes heating and curing to form a mold, the upper mold and the lower mold in the module located outside the injection mechanism can be separated by the mold opening mechanism. At this time, the product in this separated module can be taken out. After the product in the module in the injection mechanism is cured, the slide plate slides horizontally, so that the module originally located in the injection mechanism moves to the outside of the injection mechanism, and the empty module after blanking moves into the injection mechanism, that is, the blanking process and the injection molding process are carried out synchronously, which helps to ensure production efficiency; the two groups of modules are independent of each other. When the models of the two groups of modules are different, the production of two types of products can be completed in the production of the same batch, making the production process more flexible; when the models of the two groups of modules are the same, the output per unit time can be increased, which helps to improve production efficiency.

[0008] Optionally, the injection mechanism includes a mounting plate, a glue injection pipe, and a second power telescopic member. The mounting plate is vertically slidably connected to the machine table. The glue injection pipe is arranged on the mounting plate. The glue outlet of the glue injection pipe faces the glue injection groove. The second power telescopic member is used to drive the mounting plate to slide.

[0009] By adopting the above technical solution, when the mounting plate moves downward, it can drive the glue injection pipe to move downward, so that the glue outlet at the bottom of the glue injection pipe is inserted into the glue injection hole on the upper mold, so that the silicone in the glue injection pipe can better flow into the glue injection groove between the upper mold and the lower mold; after the silicone product in the glue injection groove is heated and cured, the mounting plate drives the glue injection pipe to move upward, and then the module can slide horizontally, thus avoiding interference of the glue injection pipe on the module.

[0010] Optionally, a second heating plate is fixedly connected to one side of the mounting plate close to the module. The second heating plate is used to abut against the upper mold.

[0011] By adopting the above technical solution, the first heating plate heats the lower mold, and the second heating plate heats the upper mold, so that the liquid silicone on the upper and lower sides in the glue injection groove can be evenly heated, which helps to ensure the curing effect and avoid product deformation or internal stress cracks caused by the temperature difference between the upper and lower sides.

[0012] Optionally, the mold opening mechanism includes a third power telescopic member, a support plate, and a support rod. The third power telescopic member is arranged on the machine table. The support plate is fixedly connected to the movable end of the third power telescopic member. The support rod is fixedly connected to the upper mold. The support rod is located above the support plate, so that when the support plate moves upward, it pushes the support rod upward and separates the upper mold from the lower mold.

[0013] By adopting the above technical solution, the third power telescopic member drives the support plate to move upward, and the support plate can push the support rod upward, so that the upper mold moves upward, realizing the separation of the upper mold and the lower mold, facilitating the removal of the silicone product in the glue injection groove on the top wall of the lower mold, and completing the blanking process.

[0014] Optionally, a third heating plate is arranged on the machine table. There are two third heating plates, which are arranged on both sides of the injection mechanism at intervals along the length direction of the machine table. The third heating plate is vertically slidably connected to the machine table, and the bottom wall of the third heating plate is used to abut against the top wall of the upper mold.

[0015] By adopting the above technical solution, the third heating plate abuts against the upper mold, so that the upper mold is heated by the third heating plate. That is, the module located outside the injection mechanism can be heated and insulated by the first heating plate and the third heating plate, so as to ensure the temperature consistency of this module. Therefore, when the silicone injection molding is carried out again later, it helps to ensure the curing effect and curing efficiency of the silicone.

[0016] Optionally, a spring is connected between the third heating plate and the machine table to make the bottom wall of the third heating plate abut against the top wall of the upper mold.

[0017] By adopting the above technical solution, the spring makes the third heating plate abut tightly against the upper mold, so that the third heating plate and the upper mold can be in full contact, ensuring the heat transfer effect.

[0018] Optionally, a guide post is fixedly connected to the lower mold, and a guide hole for the guide post to penetrate is provided on the upper mold; an exhaust hole is provided on the bottom wall of the glue injection groove on the lower mold, and a plugging block is vertically slidably arranged at the exhaust hole. The plugging block is frustum-shaped; a first air supply hole communicating with the exhaust hole is provided inside the lower mold, a second air supply hole communicating with the first air supply hole is provided on the guide post, the second air supply hole is used to communicate with the guide hole, a third air supply hole communicating with the guide hole is provided inside the third heating plate, a air supply member is arranged on the machine table, and an air supply pipe is connected between the air supply member and the third air supply hole.

[0019] By adopting the above technical solution, the cooperation between the guide post and the guide hole can enable the upper mold and the lower mold to be accurately closed, ensuring the injection accuracy; the frustum-shaped plugging block can plug the exhaust hole during injection to prevent the leakage of liquid silicone. And during the mold opening process, the air supply member can sequentially supply air to the air supply pipe, the third air supply hole, the second air supply hole, the first air supply hole and the exhaust hole. The air flowing upward in the exhaust hole can push the plugging block upward, so that the plugging block pushes the silicone product in the injection groove on the top wall of the lower mold upward, so that the silicone product is separated from the injection groove, facilitating the subsequent operator to conveniently take out the formed product; after the plugging block is opened, the air in the exhaust hole is discharged upward and can blow the bottom wall of the upper mold. Since the air discharged from the exhaust hole has passed through the third heating plate, the discharged air is hot air, thereby slowing down the cooling speed of the upper mold, helping to ensure the temperature consistency between the upper mold and the lower mold, and thus ensuring the curing effect of the silicone after subsequent mold closing; the air discharged from the exhaust hole can also blow off the dust and other sundries attached to the bottom wall of the upper mold, thereby realizing the cleaning of the bottom wall of the upper mold.

[0020] Optionally, a sealing gasket is arranged on the circumferential side of the plugging block, and an elastic rope is connected between the plugging block and the inner wall of the exhaust hole.

[0021] By adopting the above technical solution, the sealing gasket can enhance the sealing performance between the plugging block and the exhaust hole, preventing the liquid silicone from leaking from the exhaust hole; the elastic rope can ensure that the plugging block can return to the initial position to plug the exhaust hole after pushing up the product, ensuring the normal progress of the injection process.

[0022] Optionally, a connecting pipe is arranged on the third heating plate. One end of the connecting pipe is communicated with the third air supply hole, and the other end of the connecting pipe is provided with an exhaust pipe. The exhaust pipe is communicated with the inside of the connecting pipe. The exhaust pipe is arranged along the width direction of the machine table, and a plurality of air discharge ports are arranged on the exhaust pipe, and the air discharge ports face the module.

[0023] By adopting the above technical solution, the air in the connecting pipe can flow into the exhaust pipe, and then be horizontally discharged through the air discharge ports on the exhaust pipe to blow the silicone product pushed up by the plugging block, so that the pushed-up silicone product can be pushed by the wind force to the outside of the injection groove, thus realizing the separation of the product from the injection groove, and thus facilitating the staff wearing protective gloves to quickly take out the product, reducing the difficulty of material taking; the air discharged from the connecting pipe can also blow the top wall of the lower mold. Since the discharged air is hot air, it can keep the temperature of the lower mold, helping to ensure the temperature consistency between the lower mold and the upper mold; in addition, the discharged air can also blow off the dust and other sundries on the top wall of the lower mold, realizing the cleaning of the lower mold.

[0024] Optionally, the connecting pipe is a corrugated pipe that can expand and contract in the vertical direction, and the exhaust pipe is fixedly connected to the machine table so that the air discharge ports on the exhaust pipe always face the top wall of the lower mold.

[0025] By adopting the above technical solution, the air outlet on the exhaust duct can always face the top wall of the lower mold, ensuring that the wind discharged from the connecting pipe can accurately act on the top wall of the lower mold, which is beneficial to ensuring the pushing effect on the silicone product and maintaining the stable temperature of the lower mold.

[0026] In summary, the present application includes the following beneficial technical effects: 1. Two groups of modules are provided on the sliding plate. During the molding process of the silicone product by one group of modules, the other group of modules can open the mold and take out the molded product. Therefore, the process of taking out the product does not take too much time, which helps to improve work efficiency.

[0027] 2. When the models of the two groups of modules are different, the molding of two types of silicone products can be carried out during the production process of the same batch, thus improving the flexibility of the device.

[0028] 3. The third heating plate can heat and keep the upper mold warm during the mold opening process of the module, preventing the upper mold from cooling too quickly, thereby reducing the temperature difference between the upper mold and the lower mold, ensuring the curing effect of the liquid silicone after subsequent mold closing, and avoiding the influence of too large a temperature difference between the upper and lower molds on the subsequent silicone curing effect.

[0029] 4. During the mold opening process, the air supply component can send air into the exhaust hole, causing the plugging block to move upward. The plugging block pushes up the silicone product in the injection slot on the top wall of the lower mold. At the same time, the air supply component can also horizontally exhaust air through the connecting pipe and the exhaust duct, horizontally pushing the lifted product to one side of the injection slot, so that the product moves outside the injection slot, facilitating the subsequent operation of the operator wearing protective gloves to quickly take out the product, reducing the difficulty of material taking, and making the material taking process more convenient.

DETAILED DESCRIPTION

[0032] The following combination Figures 1-9 This application is described in further detail.

[0033] Example 1 The present application embodiment discloses a vertical external mold double slide plate liquid silicone injection machine. Figure 1 and Figure 2 The vertical external mold opening double slide plate liquid silicone injection machine comprises a machine platform 1, a mold shifting mechanism 2, an injection mechanism 4 and a mold opening mechanism 5. The mold shifting mechanism 2, the injection mechanism 4 and the mold opening mechanism 5 are all installed on the machine platform 1, the mold shifting mechanism 2 is used to move the mold, the injection mechanism 4 is used to inject liquid silicone into the mold, and the mold opening mechanism 5 is used to open the mold, so that the injection machine can complete the injection and molding process of liquid silicone.

[0034] Reference Figure 2, the mold moving mechanism 2 includes a slide plate 21, a first power telescopic member 22, a first heating plate 23, and a mold unit 24. The slide plate 21 is slidably connected to the machine table 1 along the length direction of the machine table 1. Fixed connections with telescopic dust covers 19 are provided between both ends of the slide plate 21 and the machine table 1, which can protect the internal structure. The first power telescopic member 22 is an oil cylinder. The cylinder body of the first power telescopic member 22 is horizontally and fixedly connected to the machine table 1, and the end of the piston rod of the first power telescopic member 22 is fixedly connected to the slide plate 21. Thus, the first power telescopic member 22 can drive the slide plate 21 to slide horizontally. Two first heating plates 23 are provided and are fixedly connected to the top wall of the slide plate 21 at intervals along the length direction of the machine table 1. Heating wires or heating tubes are embedded inside the first heating plates 23, which can be used for heating and temperature rising. Two sets of mold units 24 are provided, and each mold unit 24 corresponds to a first heating plate 23. The first heating plate 23 is used to heat the mold unit 24, so that the liquid silicone in the mold unit 24 is heated and cured to form the required product.

[0035] The mold unit 24 includes an upper mold 241 and a lower mold 242. The lower mold 242 is detachably and fixedly connected to the top wall of the first heating plate 23 by screws. The upper mold 241 is placed on the top wall of the lower mold 242; vertical guide posts 6 (refer to Figure 3 ) are fixedly connected to the four corners of the top wall of the lower mold 242. Vertical guide holes 2411 are opened at the four corners of the upper mold 241. The guide posts 6 slidably pass through the guide holes 2411. After the upper mold 241 is lapped on the top wall of the lower mold 242, when the lower mold 242 slides horizontally, it can drive the upper mold 241 to slide horizontally synchronously. Glue injection grooves 3 are opened on both the bottom wall of the upper mold 241 and the top wall of the lower mold 242. A through glue injection hole 2412 is opened on the upper mold 241, and the bottom end of the glue injection hole 2412 communicates with the glue injection groove 3; when the upper mold 241 and the lower mold 242 are closed, a complete glue injection space is formed between the two glue injection grooves 3 for accommodating liquid silicone. After the silicone is heated and cured, the required product can be formed. Since two sets of mold units 24 are provided, the two sets of mold units 24 can choose the same model or different models; when the models of the two sets of mold units 24 are different, products of two models can be formed in the same batch, thus meeting the needs of diversified production.

[0036] The injection mechanism 4 includes a mounting plate 41, a glue injection tube 42, and a second power telescopic member 43. The mounting plate 41 is located above the module 24. The mounting plate 41 is slidably connected to the machine table 1 in the vertical direction, and the plate surface of the mounting plate 41 is horizontal. The glue injection tube 42 is vertically arranged on the mounting plate 41, and the glue outlet of the glue injection tube 42 faces downward. The second power telescopic member 43 is an oil cylinder. The piston rod of the second power telescopic member 43 faces vertically upward, and the cylinder block of the second power telescopic member 43 is fixedly connected to the machine table 1; the end of the piston rod of the second power telescopic member 43 is fixedly connected with a connecting rod 431. The connecting rod 431 vertically slides through the machine table 1, and the top end of the connecting rod 431 is fixedly connected to the mounting plate 41. Therefore, the second power telescopic member 43 can drive the mounting plate 41 to slide vertically. When the mounting plate 41 moves downward, the mounting plate 41 drives the glue injection tube 42 to move downward, so that the glue outlet of the glue injection tube 42 is inserted into the glue injection hole 2412 on the upper mold 241, facilitating the injection of liquid silicone into the glue injection groove 3; when the silicone in the glue injection groove 3 is cured into the required product after being heated for a period of time; at this time, the mounting plate 41 drives the glue injection tube 42 to move upward, and then the module 24 slides horizontally along with the slide plate 21. Therefore, during the sliding process of the module 24, the glue injection tube 42 is not likely to interfere with the module 24.

[0037] Wherein, an adjusting oil cylinder 16 is arranged on the top wall of the mounting plate 41, and the piston rod of the adjusting oil cylinder 16 faces vertically upward; the cylinder block of the adjusting oil cylinder 16 is fixedly connected to the mounting plate 41, and the end of the piston rod of the adjusting oil cylinder 16 is fixedly connected to the glue injection tube 42. Therefore, the adjusting oil cylinder 16 can make the glue injection tube 42 slide vertically relative to the mounting plate 41, thereby adjusting the position of the glue injection tube 42.

[0038] A second heating plate 7 is also fixedly connected to the bottom wall of the mounting plate 41. The bottom wall of the second heating plate 7 can abut against the top wall of the upper mold 241 to heat up the upper mold 241, so that the liquid silicone between the upper mold 241 and the lower mold 242 can be better cured, improving the molding quality and molding efficiency.

[0039] Refer to Figure 2 and Figure 3, there are two sets of mold opening mechanisms 5, which are respectively located on both sides of the injection mechanism 4. The mold opening mechanism 5 includes a third power telescopic member 51, a support plate 52 and a support rod 53. The third power telescopic member 51 is an oil cylinder, and the piston rod of the third power telescopic member 51 is vertically upward; the cylinder body of the third power telescopic member 51 is fixedly connected to the machine table 1, and a connecting plate 511 is fixedly installed at the end of the piston rod of the third power telescopic member 51. Vertical push rods 512 are fixedly connected to both sides of the connecting plate 511, and multiple push rods 512 are provided on each side. The top of each push rod 512 on each side passes through the support plate 52, and the support plate 52 is provided with kidney-shaped holes 521 for the push rods 512 to pass through; nuts 513 are threadedly connected to both the upper and lower sides of the support plate 52 on the push rod 512, so as to fixedly connect the support plate 52 to the push rod 512. The support rod 53 is horizontally fixedly connected to the side walls on both sides of the upper mold 241, the support rod 53 is located directly above the support plate 52, and the top wall of the support plate 52 is provided with an abutting groove 522 for abutting against the support rod 53. Therefore, the third power telescopic member 51 drives the support plate 52 to move upward through the connecting plate 511 and the push rod 512, and the support plate 52 pushes the support rod 53 to move upward, so that the upper mold 241 slides upward, realizing the separation of the upper mold 241 and the lower mold 242, and then the silicone product placed in the glue injection groove 3 on the top wall of the lower mold 242 can be taken out. The setting of the kidney-shaped hole 521 facilitates adjusting the position of the support plate 52 relative to the push rod 512, so as to adapt to upper molds 241 of different sizes.

[0040] The implementation principle of Embodiment 1 is as follows: In the initial state, one set of modules 24 is located in the injection mechanism 4, and the other set of modules 24 is located outside the injection mechanism 4. The module 24 located in the injection mechanism 4 is in the mold closing state. The glue injection pipe 42 injects liquid silicone into the glue injection groove 3, and then the first heating plate 23 heats the lower mold 242, and the second heating plate 7 heats the upper mold 241, so that the silicone in the glue injection groove 3 is heated and cured. During the curing process of the silicone in this module 24, the mold opening mechanism 5 can drive the upper mold 241 in the other module 24 to move upward, and then the operator can take out the silicone product placed in the glue injection groove 3 on the top wall of the lower mold 242; after taking out the product, the upper mold 241 moves downward to complete the mold closing process.

[0041] After a period of time, the silicone in the module 24 in the injection mechanism 4 is cured. At this time, the mounting plate 41 slides upward, so that the glue injection pipe 42 moves upward to avoid the horizontal sliding process of the module 24; then the slide plate 21 slides horizontally, so that the module 24 containing the cured product moves to the outside of the injection mechanism 4, and the empty module 24 moves into the injection mechanism 4; the mounting plate 41 moves downward again, and the glue injection pipe 42 is inserted into the glue injection hole 2412 on the upper mold 241 to inject silicone, and then the above process can be repeated.

[0042] Embodiment 2 Refer toFigure 4 , the difference between this embodiment and Embodiment 1 is that a third heating plate 8 is provided on the machine table 1 in this embodiment. There are two third heating plates 8, which are arranged at intervals on both sides of the injection mechanism 4 along the length direction of the machine table 1. Convex blocks 81 are fixedly connected to the side walls at the four corners of the third heating plate 8, and through holes are provided in the convex blocks 81; a vertical rod 17 is fixedly connected to the machine table 1, and the vertical rod 17 slidably passes through the through holes in the convex blocks 81, so that the third heating plate 8 is slidably connected to the machine table 1 in the vertical direction. A spring 9 is fixedly connected between the bottom wall of the third heating plate 8 and the machine table 1, and the spring 9 is sleeved outside the vertical rod 17. The spring 9 is used to support the third heating plate 8 and for the reset of the third heating plate 8.

[0043] Under normal conditions, the bottom wall of the third heating plate 8 is at the same height as the top wall of the upper mold 241 in the mold closing state; therefore, when the upper mold 241 slides horizontally with the lower mold 242, the upper mold 241 can move to the lower part of the third heating plate 8, and the top wall of the upper mold 241 abuts against the bottom wall of the third heating plate 8. Therefore, the upper mold 241 can be heated by the third heating plate 8. That is, the upper mold 241 moved to the outside of the injection mechanism 4 can also be heated and insulated, thereby reducing the temperature difference between the upper mold 241 and the lower mold 242 in this mold set 24 outside the injection mechanism 4, facilitating ensuring the subsequent uniform heating of the liquid silicone and ensuring the curing effect.

[0044] Refer to Figure 6 and Figure 7 , a vertically arranged exhaust hole 2421 is provided in the lower mold 242, and the top end of the exhaust hole 2421 is communicated with the bottom wall of the glue injection groove 3; a plugging block 10 is slidably arranged at the top end of the exhaust hole 2421 in the vertical direction. The plugging block 10 is arranged in a frustum shape, and the wall surface at the top end of the exhaust hole 2421 is arranged in a frustum shape adapted to the plugging block 10. An elastic cord 13 is fixedly connected between the bottom wall of the plugging block 10 and the inner wall of the bottom end of the exhaust hole 2421. Refer to Figure 8 , vertical guide columns 6 are fixedly connected to the four corners of the top wall of the lower mold 242, and guide holes 2411 for the guide columns 6 to penetrate are provided at the four corners of the upper mold 241. The guide holes 2411 penetrate through the upper mold 241. The cooperation between the guide columns 6 and the guide holes 2411 can ensure the accuracy when the upper mold 241 and the lower mold 242 are closed.

[0045] Refer to Figure 6 and Figure 7, Under normal conditions, the elastic rope 13 is in a taut state. Therefore, the elastic rope 13 makes the plugging block 10 tightly press against the side wall at the top of the exhaust hole 2421. At this time, the top wall of the plugging block 10 is flush with the bottom wall of the glue injection groove 3, and the plugging block 10 plugs the exhaust hole 2421. Therefore, the silica gel in the glue injection groove 3 cannot flow into the exhaust hole 2421, which helps to ensure the smooth progress of the product forming process. A sealing gasket is fixedly bonded to the periphery of the plugging block 10. The sealing gasket is made of rubber, which can enhance the plugging effect.

[0046] Refer to Figure 6 , Figure 7 and Figure 8 , Inside the lower mold 242, a first air supply hole 2422 is provided. There are four first air supply holes 2422 and they are arranged at intervals along the circumferential direction. Each first air supply hole 2422 corresponds to a guide post 6. A vertically arranged second air supply hole 61 is provided on each guide post 6, and the second air supply hole 61 penetrates through the guide post 6. One end of the first air supply hole 2422 is communicated with the bottom end of the exhaust hole 2421, and the other end of the first air supply hole 2422 is communicated with the bottom end of the second air supply hole 61 on the corresponding guide post 6. When the upper mold 241 and the lower mold 242 are in the closed mold state, the guide post 6 is inserted into the guide hole 2411. Therefore, at this time, the top end of the second air supply hole 61 is communicated with the guide hole 2411.

[0047] Refer to Figure 8 and Figure 9 , Inside the third heating plate 8, a third air supply hole 82 is provided. There are four third air supply holes 82 and they are arranged at intervals along the circumferential direction. Each third air supply hole 82 corresponds to a guide hole 2411. One end of the third air supply hole 82 is communicated with the top end of the guide hole 2411, and the other end of the third air supply hole 82 is connected with an air supply pipe 12. The end of the air supply pipe 12 is connected with an air supply member 11 (refer to Figure 5 ), and the air supply member 11 is a fan; in other embodiments, the air supply member 11 can also be an air pump or a gas storage tank. The end of the air supply pipe 12 connected to the third heating plate 8 is a flexible pipe. Therefore, the sliding process of the third heating plate 8 is not likely to affect the connection between the air supply pipe 12 and the third heating plate 8.

[0048] Refer to Figure 7 , Figure 8 and Figure 9, so during the mold opening process of the module 24 located outside the injection mechanism 4, the air supply member 11 can blow air into the third air supply hole 82 through the air supply pipe 12. The air in the third air supply hole 82 flows into the exhaust hole 2421 through the guiding hole 2411, the second air supply hole 61, and the first air supply hole 2422 in sequence. The air flow in the exhaust hole 2421 flows vertically upward and pushes the plugging block 10 upward. The plugging block 10 can push the silica gel product in the glue injection groove 3 on the top wall of the lower mold 242 upward, so that the product moves above the glue injection groove 3, facilitating the separation of the product from the glue injection groove 3. Thus, it is more convenient for the operator to remove the product subsequently and complete the material taking process. While the plugging block 10 moves upward, the top end of the exhaust hole 2421 opens. Therefore, the air in the exhaust hole 2421 can flow upward and blow the bottom wall of the upper mold 241. Since the blown air has been heated by the third heating plate 8, it helps to maintain the temperature of the bottom wall of the upper mold 241 and can prevent the bottom wall of the upper mold 241 from cooling too quickly.

[0049] Refer to Figure 6 and Figure 8 , a vertical connecting pipe 14 is also fixedly arranged on the third heating plate 8, and the connecting pipe 14 is a corrugated pipe. The top end of the connecting pipe 14 is fixedly connected to the third heating plate 8, and the top end of the connecting pipe 14 is communicated with the third air supply hole 82; the bottom end of the connecting pipe 14 is fixedly connected with an exhaust pipe 15, and the connecting pipe 14 is communicated with the exhaust pipe 15. The exhaust pipe 15 is fixedly connected to the machine table 1 through a connecting rod 18, and the exhaust pipe 15 and the top wall of the lower mold 242 are at the same height; the exhaust pipe 15 is arranged along the width direction of the machine table 1, and an exhaust port 151 is opened on one side of the exhaust pipe 15 close to the module 24. There are multiple exhaust ports 151 and they are evenly spaced along the length direction of the exhaust pipe 15. Therefore, the air supply member 11 can also convey the heated air into the connecting pipe 14. The air in the connecting pipe 14 then flows into the exhaust pipe 15 and is discharged through the exhaust port 151, so as to blow the product on the top wall of the lower mold 242, so that the product lifted by the plugging block 10 can be horizontally blown by the air discharged from the exhaust port 151 to the outside of the glue injection groove 3, preventing the product lifted by the plugging block 10 from falling back into the glue injection groove 3 again. Thus, it is convenient for the operator to quickly take out the formed product, reduce the material taking difficulty, and thus weaken the influence of the protective gloves on the flexibility of the operator.

[0050] Since the connecting pipe 14 is a corrugated pipe and the exhaust pipe 15 is fixedly connected to the machine table 1, the position of the exhaust pipe 15 remains unchanged, and the exhaust pipe 15 can stably blow air on the product on the top wall of the lower mold 242. The air blown out by the exhaust pipe 15 is hot air, so it also helps to maintain the temperature of the top wall of the lower mold 242.

[0051] In this embodiment, each power telescopic member is an oil cylinder. In other embodiments, the power telescopic member can also be a cylinder or an electric push rod 512.

[0052] The implementation principle of Example 2 is as follows: during the mold opening process of the mold group 24 located outside the injection mechanism 4, the upper mold 241 slides upward. During the sliding process of the upper mold 241, the air discharged by the air supply member 11 can flow into the third air supply hole 82 through the air supply pipe 12. After being heated and heated, the air in the third air supply hole 82 can flow into the guide hole 2411, the second air supply hole 61, the first air supply hole 2422 and the exhaust hole 2421 in sequence. The hot air in the exhaust hole 2421 flows upward and drives the blocking block 10 to slide upward. The blocking block 10 can push the silicone product in the injection groove 3 on the top wall of the lower mold 242 to move upward. At the same time, part of the air in the third air supply hole 82 also flows into the connecting pipe 14 and the exhaust pipe 15, and then is discharged horizontally through the exhaust port 151 on the exhaust pipe 15, thereby pushing the silicone product lifted by the blocking block 10 to one side of the injection groove 3, so that the molded silicone product is separated from the injection groove 3. When the upper mold 241 moves to the top, the upper mold 241 remains stationary. At this time, the operator wearing protective gloves can easily take out the product outside the glue injection groove 3, thereby completing the unloading process.

[0053] After the product is taken out, the upper mold 241 slides downward again to close the mold. After closing the mold, the air blowing is stopped. At this time, the module 24 is kept warm by the first heating plate 23 and the third heating plate 8, so as to ensure the consistency of temperature between the upper mold 241 and the lower mold 242, and ensure the subsequent curing effect of the liquid silicone.

[0054] The above are optional embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
