Description

Technical Field

[0001] The invention relates to the technical field of molding equipment, in particular to a double-station multi-purpose slide plate vertical injection molding machine with a vulcanization function. Background Art

[0002] Injection molding machine is also called injection molding machine or injection machine. It is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics. It is divided into vertical, horizontal and all-electric types. The injection molding machine can heat the plastic and apply high pressure to the molten plastic to make it ejected and fill the mold cavity.

[0003] The functions of existing injection molding machines are relatively simple. They are generally only used for injection molding of products, but cannot be used for vulcanization molding of products. If a vulcanization process is required, special vulcanization equipment is required. This leads to the need for some companies that need to produce both injection molded products and vulcanized products to purchase injection molding machines and vulcanizers at the same time, which not only increases the cost of equipment purchase, but also increases the floor space, worker training content and product production costs. At the same time, existing equipment generally uses molds with a single parting surface, and the amount of products produced at one time is small, and the product processing efficiency is not high. When the vulcanizer is operating, the rubber is often placed manually. Similarly, the product processing efficiency is not high. Existing injection molding machines and vulcanizers have more or less the above-mentioned shortcomings. Summary of the invention

Detailed implementation manners

[0034] The following are specific embodiments of the present invention and in combination with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0035] As Figure 1-6 shown, in an embodiment of the present application, a double - station multi - purpose slide - type vertical injection molding machine with vulcanization function includes a frame 1. A lower platen 2 is provided on the frame 1. An inverted clamping cylinder 3 is provided below the lower platen 2. The lower end of the clamping cylinder 3 is connected to a first power plate 4. The first power plate 4 is connected to an upper platen 5 through guide columns. The upper platen 5 is arranged above the lower platen 2. An injection mechanism 6 is provided above the upper platen 5. A support plate 7 is provided above the lower platen 2. A slide plate 8 is provided above the support plate 7. A first heating plate 9 is provided above the slide plate 8. A second heating plate 50 is provided below the upper platen 5. The front and rear ends of the support plate 7 protrude from the lower platen 2. Lifting mechanisms 30 are provided at the front and rear ends of the support plate 7. A flipping auxiliary assembly 40 cooperating with the lifting mechanism 30 is mounted on the frame 1. A vacuum pump 80 for providing a vacuum environment is provided below the frame 1.

[0036] In this embodiment, the vertical injection molding machine can be used for product injection molding, injection molding plus vulcanization of products, and even for separate vulcanization. It can be used for injection molding or vulcanization of single parting surface molds and multi-parting surface molds. With multiple functions, it can replace multiple dedicated devices, saving equipment purchase and maintenance costs, having high flexibility, and adapting to the production requirements of different products. At the same time, it has high production efficiency, can reduce line change time and labor, improve utilization rate, and achieve the purpose of cost reduction and efficiency increase.

[0037] Among them, the frame 1 is used for the installation of various mechanisms and components. The lower platen 2 is used for the installation of the mold clamping cylinder 3. The mold clamping cylinder 3 can drive the first power plate 4 to move up and down, and then drive the upper platen 5 and the injection mechanism 6 thereon to move up and down. The lower part of the upper platen 5 is connected to the upper template of the mold. Through the up and down movement of the upper platen 5, the mold is clamped, facilitating the injection mechanism 6 to inject materials into the mold, and then realizing the molding of the product in the mold cavity. The support plate 7 is used to connect the slide plate 8, facilitating the front and back sliding of the slide plate 8. The upper part of the slide plate 8 is used for the installation and support of the lower template of the mold. It combines with the upper template of the mold connected to the lower part of the upper platen 5 to realize the mold clamping of the mold. The first heating plate 9 and the second heating plate 50 are respectively installed on the slide plate 8 and the upper platen 5, and are used for simultaneous upper and lower heating of the installed mold, and can be used for the molding of products that need to be heated and cured and the heating vulcanization of products. The jacking mechanism 30 is used for opening the mold cavity of the injection molding or vulcanization mold. Through the jacking mechanism 30, the templates of the mold can be jacked up one by one, opening each parting surface, facilitating the removal of the product in the mold cavity. The flipping auxiliary component 40 is used for flipping the templates of the mold. For some requirements that need to open the mold cavity wider, adding the flipping auxiliary component 40 can cooperate with the jacking mechanism 40 to flip the jacked-up template after the template is jacked up a certain height by the jacking mechanism 40, so that there is no obstruction above the mold cavity, facilitating the removal of the product in the mold cavity and the vulcanization operation of some products that need to manually put rubber material into the mold cavity. The vacuum pump 80 is used to evacuate the mold cavity, which can reduce the generation of internal bubbles and shrinkage holes in the molded product in the mold cavity, thereby improving the quality and appearance of the product.

[0038] In this embodiment, the slide plate 8 can move back and forth, realizing the front and back alternating movement of the two molds installed thereon, so that one of the molds is located below the upper platen 5, facilitating injection molding, while the other template is located above the front jacking mechanism 30 or above the rear jacking mechanism 30. The jacking mechanism 30 jacks up and opens the mold located above it, ensuring that there are always two working stations working, which can double the working efficiency of the injection molding operation, save energy consumption at the same time, reduce production costs, and meet the production demand of large quantities.

[0039] Such as Figure 7As shown in the figure, in an embodiment of the present application, the jacking mechanism 30 includes a first jacking component 301 and a second jacking component 302. The first jacking component 301 includes two first jacking cylinders 3011 that are installed upside down and symmetrically arranged below the support plate 7. The two first jacking cylinders 3011 are connected to a horizontally arranged second power plate 3012. Above the second power plate 3012, two first jacking plates 3013 are connected. The two first jacking plates 3013 are symmetrically arranged on the left and right sides of the support plate 7. Above the second power plate 3012, several first jacking rods 3014 are provided. Above the several first jacking rods 3014, a third power plate 3015 is provided. Above the third power plate 3015, two second jacking plates 3016 are connected. The two second jacking plates 3016 are respectively arranged below the two first jacking plates 3013.

[0040] The two second jacking components 302 are symmetrically arranged at the left and right ends of the third power plate 3015. The second jacking component 302 includes a second jacking cylinder 3021. The second jacking cylinder 3021 is installed on the third power plate 3015. The upper end of the second jacking cylinder 3021 is connected to a connecting rod 3022. Above the connecting rod 3022, a third jacking plate 3023 is provided. The third jacking plate 3023 is arranged above the first jacking plate 3013.

[0041] In this embodiment, the jacking mechanism 30 includes a first jacking component 301 and a second jacking component 302. Among them, the first jacking component 301 has two jacking structures, including the first jacking plate 3013 and the second jacking plate 3016, which can realize the jacking of two templates, that is, the jacking of the multi-parting surface templates of the combined mold cavity, such as the jacking of the middle template with two parting surfaces and the jacking of the middle two templates with three parting surfaces. Through the cooperation of the second jacking component 302 and the first jacking component 301, the jacking of the middle three templates of the four parting surfaces can be realized, and the mold opening action of the mold cavity can be realized.

[0042] Specifically, the first jacking cylinder 3011 can drive the second power plate 3012 to move upward. Through the second power plate 3012, the first jacking plate 3013 can be driven to rise. The two first jacking plates 3013 can jack up the template of the mold, realizing the mold opening action of one parting surface. When the second power plate 3012 rises to a certain height, the upper end of the first jacking rod 3014 on the second power plate 3012 contacts the third power plate 3015. Through the continuous rise of the second power plate 3012, the third power plate 3015 can be driven to rise synchronously. Through the third power plate 3015, the second jacking plate 3016 is driven to rise, jacking up a template below the already jacked-up template, realizing the mold opening of another parting surface.

[0043] In this embodiment, the second jacking assembly 302 includes a second jacking cylinder 3021, a connecting rod 3022, and a third jacking plate 3023. The second jacking cylinder 3021 can drive the connecting rod 3022 to move up and down, driving the third jacking plate 3023 to move up and down, and the uppermost template of the combined mold cavity is jacked up through the third jacking plate 3023. That is, through the first jacking assembly 301 and the second jacking assembly 302, the jacking of the middle three templates of the four parting surfaces can be realized, and the mold opening of the combined mold cavity can be achieved. It can greatly improve the molding efficiency of products, accelerate the production efficiency of products, can form multiple products at one time, reduce the cycle time, reduce the unit cost, improve the equipment utilization rate, make the machine running time more effective, reduce energy consumption or man-hours, and is suitable for mass production operations.

[0044] In this embodiment, at least two guide shafts are provided on both the left and right sides of each mold template. Correspondingly, a plurality of jacking grooves for cooperating with the guide shafts are provided on the first jacking plate 3013, the second jacking plate 3016, and the third jacking plate 3023. The jacking grooves are semi-circular structures, which have better mechanical stability, processing convenience, and use reliability, have convenient insertion, can reduce stress concentration, avoid stress cracks, can be used for a long time, and at the same time facilitate the rotation of the guide shafts therein, have better guiding and supporting properties for the guide shafts, and can realize the flipping of the template, that is, cooperate with the flipping auxiliary assembly 40 to realize the flipping of the template. At the same time, at least two guide shafts on both the left and right sides of each mold template can ensure the stable jacking of the jacking plate to the template, ensuring stable and safe mold opening.

[0045] In this embodiment, the maximum jacking stroke of the first jacking plate 3013 can reach 300 mm, the maximum stroke of the second jacking plate 3016 can reach 150 mm, and the maximum jacking stroke of the third jacking plate 3023 can reach 450 mm, realizing large-stroke jacking mold opening, which is more convenient for taking out the products in the mold cavity. The first jacking assembly 301 and the second jacking assembly 302 realize independent jacking actions. The second jacking plate 3016 can realize the linkage of the first jacking plate 3013 and the second jacking plate 3016 through the limited combination of the third power plate 3015 and the first ejector rod 3014, making the jacking structure more simplified, while reducing the demand and installation of the power source, and the structural design is more ingenious.

[0046] Continue to refer to Figure 7 , based on the above embodiment, in another embodiment of the present application, the connecting rod 3022 is provided with a thread and is screwed with a nut, and the nut is arranged below the second jacking plate 3016 corresponding to the third jacking plate 3023.

[0047] In this embodiment, the thread on the connecting rod 3022 is used to connect the nut and facilitate the height adjustment of the nut. The nut is arranged below the second lifting plate 3016. When the second lifting cylinder 3021 drives the connecting rod 3022 to rise, the nut can contact the second lifting plate 3016 and push the second lifting plate 3016 to rise synchronously with the third lifting plate 3023, further lifting the second lifting plate 3016 by a certain distance, so that the template lifted by the corresponding second lifting plate 3016 is further lifted by a certain distance, facilitating the removal of the product in the corresponding mold cavity and improving safety.

[0048] Continue to refer to Figure 7 , based on the above embodiment, in another embodiment of the present application, a plurality of second ejector rods 3017 are provided on the second power plate 3012 and pass through the third power plate 3015, and a third lifting assembly 303 is provided above the second ejector rods 3017.

[0049] In this embodiment, through the arrangement of the second ejector rods 3017, it is convenient to install the third lifting assembly 303. The third lifting assembly 303 is used to lift the product in the mold cavity upward to assist in product demolding and blanking. The second ejector rod 3017 and the third lifting assembly 30 can be fixedly connected or movably abutted. When the second ejector rod 3017 is fixedly connected to the third lifting assembly 30, it is ensured that when the second power plate 3012 rises, the third lifting assembly 30 can be driven to rise, and the product in the mold cavity is lifted upward by the third lifting assembly 30 to assist in demolding the product in the mold cavity of the lowermost parting surface. When the second ejector rod 3017 is movably abutted to the third lifting assembly 30, when the second power plate 3012 is in the reset state, the second ejector rod 3017 does not contact the third lifting assembly 30. When the second power plate 3012 rises to a certain height, the second ejector rod 3017 contacts and abuts against the third lifting assembly 30, and then as the second power plate 3012 continues to rise, the third lifting assembly 30 can be driven to rise synchronously, so that the third lifting assembly 30 can be inserted into the mold cavity of the mold installed above the slide plate 8 to eject the product in the mold cavity of the mold.

[0050] Please refer to Figure 8 , Figure 9 As shown in

[0051] In this embodiment, the fourth power plate 3031 is used for the installation of the third ejector rod 3032. By driving the fourth power plate 3031 to rise through the second ejector rod 3017, the third ejector rod 3032 is driven to rise, thereby realizing the ejection of the product in the mold cavity of the mold on the slide plate 8 that slides above the support plate 7 and reaches above the lifting mechanism 30.

[0052] In this embodiment, when the second ejector rod 3017 is fixedly connected to the third lifting assembly 30, a third lifting cylinder 3034 is provided below the fourth power plate 3031. At this time, the second ejector rod 3017 is fixedly connected to the third lifting cylinder 3034. The second power plate 3012 can drive the second ejector rod 3017 and the third lifting cylinder 3034 to lift and lower synchronously, ensuring that the third power plate 3015 does not interfere with the third lifting assembly 30. The third lifting cylinder 3034 can drive the fourth power plate 3031 to lift and lower, driving the third ejector rod 3032 on the fourth power plate 3031 to lift and lower, realizing the ejection of the product in the mold cavity. At this time, the third lifting cylinder 3034 ensures that the third lifting assembly 303 is an independent control structure, facilitating the independent control of the third lifting assembly 303.

[0053] In this embodiment, when the second ejector rod 3017 is in movable abutment with the third lifting assembly 30, the fourth power plate 3031 is movably arranged above the third power plate 3015, and a pull rod 3033 is connected between the fourth power plate 3031 and the third power plate 3015. When the second power plate 3012 rises, it can drive the second ejector rod 3017 to rise until the second ejector rod 3017 contacts the fourth power plate 3031 and drives the fourth power plate 3031 and the third ejector rod 3032 to rise synchronously, realizing the ejection of the product formed in the mold cavity. When the third power plate 3015 descends, it can drive the fourth power plate 3031 to descend synchronously through the pull rod 3033, so that the third ejector rod 3032 withdraws from the mold cavity and the slide plate 8 and enters the support plate 7, preventing the third ejector rod 3032 of the third lifting assembly 30 from interfering with the forward and backward sliding of the slide plate 8.

[0054] Please refer to Figure 11 As shown, in another embodiment of the present application, the injection mechanism 6 includes a syringe barrel 61 movably erected on the upper platen 5. The syringe barrel 61 is connected with two seat-in cylinders 62. A screw 63 is arranged in the syringe barrel 61. The upper end of the screw 63 is connected with a hydraulic motor 64, and the hydraulic motor 64 is connected with two injection cylinders 65.

[0055] In this embodiment, the injection mechanism 6 adopts a four-cylinder structure with double seat-in cylinders 62 and double injection cylinders 65, which can ensure stable material injection. The two seat-in cylinders 62 and the two injection cylinders 65 both adopt an inverted structure, which can minimize the overall height of the injection mechanism 6, lower the center of gravity of the whole machine, and then reduce the height of the entire injection molding machine, thereby reducing the space occupancy rate of the whole equipment. Moreover, with the seat-in cylinders 62 and the injection cylinders 65 inverted, the pressure transmission path is shorter and more direct during the glue injection process, which can reduce the pressure loss caused by the skew or eccentricity of the seat-in cylinders 62 and the injection cylinders 65, reduce the occurrence probability of defects such as product flash and sink marks, and can ensure faster and more stable injection speed and pressure response, which is beneficial to achieving high-precision injection molding. The two seat-in cylinders 62 are connected to the injection barrel 61 through the seat-in plate 66. By driving the seat-in plate 66 to move up and down by the seat-in cylinders 62, the injection barrel 61 can be driven to move up and down. Through the two seat-in cylinders 62, it can be ensured that the injection barrel 61 can stably and accurately dock with the glue inlet of the mold and separate from the mold after injection. The two injection cylinders 65 are inverted on the seat-in plate 66, and their piston rods are connected to the injection plate 67. The injection plate 67 is connected to the screw 63 and the hydraulic motor 64. When the injection cylinders 65 drive the injection plate 67 to move up and down, the hydraulic motor 64 and the screw 63 can be driven to move up and down synchronously, which can cooperate with the rotation of the screw 63 to inject the material in the injection barrel 61 into the mold cavity, accelerate the material injection speed, ensure sufficient mixing of the material, reduce the defects of the molded products (such as black spots, bubbles, etc.), improve the equipment efficiency, and significantly improve the efficiency of the injection molding process and the product quality.

[0056] Please refer to Figure 5 As shown in the figure, in another embodiment of the present application, auxiliary demolding structures 70 are provided below the upper platen 5, and the two auxiliary demolding structures 70 are arranged left and right.

[0057] In this embodiment, by providing the auxiliary demolding structures 70 on the upper platen 5, it can assist in the demolding of the topmost template of the mold from other templates, preventing the other templates of the mold from rising together with the topmost template when the upper platen 5 rises, thereby causing equipment damage or safety accidents. The two auxiliary demolding structures 70 are respectively arranged on both sides of the movement direction of the slide plate 8, which can prevent the auxiliary demolding structures 70 from affecting the forward and backward movement of the other templates of the mold along with the slide plate 8.

[0058] At the same time, by arranging the auxiliary demolding structures 70 on both sides of the mold instead of inside the mold, the mold making difficulty, mold repair difficulty and manufacturing cost can be reduced.

[0059] Please refer to Figure 12As shown in the figure, based on the above embodiments, in another embodiment of the present application, the auxiliary demolding structure 70 includes a pressing block 701. The pressing block 701 is arranged front and back, and limiting protrusions 7012 are provided below both the front and rear ends. At least two mounting holes 7011 are provided above the pressing block 701. A spring 703 that abuts against the upper platen 5 is provided in each mounting hole 7011. The front and rear ends of the pressing block 701 are movably connected to a smooth rod bolt 702, and the smooth rod bolt 702 is screwed to the upper platen 5. Two receiving blocks 704 are abutted below the pressing block 701, and the receiving blocks 704 are installed on the second template from top to bottom of the injection mold.

[0060] In this embodiment, the pressing block 701 is used to cooperate with the receiving block 704. A downward force is provided to the pressing block 701 by the spring 703. When the mold is opened, the force of the spring 703 is applied to the receiving block 704 through the pressing block 701, and then transmitted to the second template from top to bottom in the mold through the receiving block 704. It can prevent the second template from rising synchronously with the first template when the topmost template rises with the upper platen 5, which may lead to the failure of the opening of the topmost parting surface. At the same time, if the second template above rises with the first template, without support and traction, the second template will fall, which may lead to damage to the mold and equipment, and may even cause safety accidents in severe cases. The mounting hole 7011 is used for the installation of the smooth rod bolt 702. The upper end of the smooth rod bolt 702 is screwed to the upper platen 5 to realize the movable installation of the pressing block 701. The mounting hole 7011 is used for the installation and limitation of the spring 703. When the mold between the upper platen 5 and the slide plate 8 is closed, the pressing block 701 presses tightly on the receiving block 704. At this time, the spring 703 is in a compressed state, storing elastic potential energy. When the topmost template of the mold moves upward with the upper platen 5, the elastic potential energy of the spring 703 is released, pressing the pressing block 701 to move downward relative to the smooth rod bolt 702, so that the pressing block 701 presses the receiving block 704 on the second template from top to bottom of the mold, keeping it stationary, and assisting in the separation of the topmost template of the mold from the second template above, that is, realizing the auxiliary demolding ability.

[0061] In this embodiment, the pressing block 701, the smooth rod bolt 702, the spring 703 and the receiving block 704 are all independent structures arranged outside the mold. The structure is simple, the debugging is convenient and easy, the requirement for the installation accuracy is relatively low, and the dimensional accuracy and material of the structure itself are not required to be high. At the same time, the installation, disassembly and maintenance are convenient.

[0062] Please refer to Figure 1 、 Figure 6 and Figure 12 As shown in the figure, in another embodiment of the present application, a translation cylinder 2 is connected to both the left and right sides of the slide plate 8. The translation cylinder 2 is fixed to the lower platen 2. A first heat insulation plate 10 is provided below the first heating plate 9, and a second heat insulation plate 60 is provided above the second heating plate 50.

[0063] In this embodiment, the translation cylinder 2 is used to drive the slide plate 8 to slide back and forth, so as to realize the front-back transposition of the mold installed above the slide plate 8, and realize the swapping of the mold between the front-side lifting mechanism 30, the middle injection position and the rear-side lifting mechanism 30, ensuring that there is always a set of molds at the middle injection position, and the other set of molds is located above one of the two lifting mechanisms 30, so as to realize double-station synchronous operation and improve the operation efficiency. The first heat insulation plate 10 is used for heat insulation between the first heating plate 9 and the slide plate 8, and the second heat insulation plate 60 is used for heat insulation between the second heating plate 50 and the upper platen 5, preventing the heat on the first heating plate 9 and the second heating plate 50 from being transferred out, resulting in equipment damage, safety hazards and energy waste.

[0064] Please refer to Figure 10 As shown, in another embodiment of the present application, the flipping auxiliary assembly 40 includes position-adjusting mounting plates 401. The two position-adjusting mounting plates 401 are installed on the upper left and right sides of the frame 1. A plurality of position-adjusting holes 4011 are provided at the front and rear sides of the position-adjusting mounting plate 401 at upper and lower intervals. A flipping shaft 402 is respectively connected between the front and rear sides of the two position-adjusting mounting plates 401 through the position-adjusting holes 4011. A plurality of bearings 403 are provided on both flipping shafts 402.

[0065] In this embodiment, the position-adjusting mounting plate 401 is used for installing the flipping shaft 402 and can facilitate the height position adjustment of the flipping shaft 402, which is realized through the position-adjusting holes 4011 provided thereon. The position-adjusting holes 4011 at different height positions are used to adjust the height of the flipping shaft 402. The flipping shaft 402 is used for installing the bearings 403. Through the bearings 403, one side of the template to be flipped can be pressed. As the template rises, the template is flipped. The position-adjusting mounting plate 401 is installed on the frame 1 and is located on the left and right sides of the lower platen 2. The structure is firmly installed, has strong supporting ability and is convenient for disassembly, thereby facilitating the height adjustment of the flipping shaft 402.

[0066] Specifically, when the lifting mechanism 30 jacks up the template to open the mold, the template to be flipped rises with the lifting mechanism 30 and contacts the bearing 403. The bearing 403 presses the side of the template corresponding to the bearing 403. The template rotates with the guide shaft close to the bearing 403 as the support point, and the side of the template far from the bearing 403 tilts upward, realizing the flipping and opening of the template, increasing the mold opening space and facilitating the taking out of the molded product in the mold cavity.

[0067] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the scope of protection of the present invention.
