[0001] This utility model relates to the field of horizontal injection molding machine technology, specifically a vertical injection mechanism for a horizontal injection molding machine. Background Technology

[0002] The injection units of existing injection molding machines are mainly divided into horizontal and vertical types. Moreover, the existing injection molding machine structure is divided into a clamping mechanism, frame, control system and injection unit. The integrated design allows for better operation when the required actions are achieved. The injection unit mainly includes a seat cylinder, injection cylinder, material tube, hydraulic motor and screw assembly. This part of the assembly can quickly and sequentially realize docking, feeding and injection molding actions.

[0003] However, the above-mentioned injection device still has shortcomings in use: the injection device is usually fixed on the frame of the injection machine, the fixed mold or the moving mold, which makes the position of the material tube on the injection device unable to be adjusted. After changing different molds, the gate position of the corresponding mold changes. At this time, the material tube cannot be connected to the gate of the mold after descending. Therefore, it is necessary to purchase a new machine. It has the disadvantages of small adaptability and large cost investment.

[0004] Therefore, this utility model provides a vertical injection mechanism for a horizontal injection molding machine. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a vertical injection mechanism for a horizontal injection molding machine to solve the problems mentioned in the background art. This utility model has the function of adjusting the front and rear position of the vertical barrel, and can be connected with the gates on different molds, eliminating the need to purchase new machines and reducing cost investment.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a vertical injection mechanism for a horizontal injection molding machine, including an injection section and a template. A fixing plate is provided on the top of the template, and a support plate is provided on the top of the fixing plate. The support plate is connected to the fixing plate through a slide rail assembly. One side of the support plate is connected to the fixing plate through a sliding cylinder. The injection section includes a positioning plate at the bottom and a vertically movable barrel. A clearance opening is provided in the middle of the positioning plate, through which the vertical barrel can pass. The positioning plate is fixedly mounted on the upper surface of the support plate.

[0007] Furthermore, one side of the fixing plate is flush with the mounting surface of the template, and the upper end surface of the support plate has a through hole near one end and opposite to the clearance opening.

[0008] Furthermore, the slide rail assembly includes a slide plate and a guide rail located inside the slide plate. The slide plate is fixedly mounted on the top of the fixed plate, and the guide rail is fixedly mounted on the bottom of the support plate.

[0009] Furthermore, a connecting plate is fixedly connected to one side of the support base plate, a support plate is fixedly connected to one side of the fixed plate, one end of the cylinder body of the slide cylinder is fixedly connected to one side of the support plate, and the actuating shaft is fixedly connected to one side of the connecting plate.

[0010] Furthermore, the injection section includes an injection cylinder and a seat cylinder located on one side of the injection cylinder. The injection cylinder and the seat cylinder are located above the positioning plate. A connecting seat is fixedly connected to the outer wall of the injection cylinder body. One end of the seat cylinder body is fixedly installed on the top of the connecting seat, and its output shaft is fixedly connected to the upper end face of the positioning plate. The injection cylinder body is connected to the vertical material cylinder through an adapter seat.

[0011] Furthermore, it also includes template two and reinforcing seat. The reinforcing seat is fixedly installed on the top of template two.

[0012] Furthermore, one end of the reinforcing seat is flush with the mounting surface of the template two.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. In this utility model, a fixing plate is fixedly installed on the top of the template, and a support slide that can move back and forth is installed on the top of the fixing plate. Then, a positioning plate that is fixedly connected to the top of the support slide is installed at the bottom of the injection part. Thus, by controlling the back and forth movement of the support slide, the position of the vertical material tube on the injection part in the front and back direction can be adjusted, which facilitates the docking of gates on different molds installed on the injection molding machine. There is no need to purchase a new machine, thus reducing cost investment.

[0015] 2. In this utility model, one end of the fixed plate is flush with the mounting surface of the template, which makes it easier to control the support slide to drive the entire injection part away from the space above the mold after parting, so that the external material picking equipment can automatically pick up the material.

[0016] 3. In this utility model, by fixing a reinforcing seat on the top of the template two, and then setting a sliding shaft on the top of the reinforcing seat, and opening a limiting groove at one end of the support plate to fit into the sliding shaft, the strength of the support plate against bending deformation is greatly improved after it is inserted into the sliding shaft, so that the nozzle at the bottom of the vertical barrel can be precisely connected with the gate.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please see Figures 1 to 3 This utility model provides a technical solution: a vertical injection mechanism for a horizontal injection molding machine, including an injection unit 1 and a template 8. A fixing plate 2 is provided on the top of the template 8, which serves as a mounting plate for either the moving or fixed mold. A support plate 3 is provided on the top of the fixing plate 2. The support plate 3 is connected to the fixing plate 2 via a slide rail assembly, which allows the support plate 3 to move back and forth relative to the fixing plate 2. Specifically, the slide rail assembly includes a slide groove plate 5 and a guide rail 6 whose bottom is located within the slide groove plate 5. The slide groove plate 5 is fixedly mounted on the top of the fixing plate 2, and the guide rail 6 is fixedly mounted on the bottom of the support plate 3. One side of the support plate 3 is connected to the fixing plate 2 via a sliding cylinder 4. The sliding cylinder 4 provides driving force for the back-and-forth movement of the support plate 3. Specifically, a connecting plate 32 is fixedly connected to one side of the support plate 3, and a support plate 21 is fixedly connected to one side of the fixing plate 2. One end of the cylinder body of the sliding cylinder 4 is fixedly connected to one side of the support plate 21, and the actuating shaft 41 is fixedly connected to one side of the connecting plate 32.

[0023] The injection unit 1 includes a positioning plate 11 at the bottom and a vertically movable barrel 12. The positioning plate 11 supports the entire injection unit 1 and is fixedly mounted on the upper surface of the support plate 3. The forward and backward movement of the support plate 3 can drive the entire injection unit 1 to move forward and backward through the positioning plate 11. The positioning plate 11 has a clearance opening 111 in the middle, through which the vertical barrel 12 can pass. When the positioning plate 11 moves horizontally above the mold gate, the vertical barrel 12 moves downward and passes through the clearance opening 111 to align with the gate on the mold, facilitating the injection of hot melt material. Because the support plate 3 can move forward and backward, the forward and backward position of the injection unit 1 can be adjusted, making it convenient for the injection unit 1 to be used for injection molding of different molds. Specifically, different molds have different gate positions when installed on a horizontal injection molding machine. By adjusting the position of the injection unit 1, it can align with the gate on the currently installed mold on the injection molding machine. Therefore, when producing two-color or other injection molded products, there is no need to purchase a new machine; only the position of the support plate 3 needs to be adjusted. This has the advantages of expanding applicability and reducing production input.

[0024] In this embodiment, one side of the fixing plate 2 is flush with the mounting surface of the template 8. The upper end of the support plate 3 is provided with a through hole 31 near one end and opposite to the clearance opening 111. After injection molding is completed, the vertical barrel 12 is retracted, and then the support plate 3 is moved so that the entire injection part 1 leaves the space above the mold. At this time, the fixing plate 2 will not occupy the space, which makes it convenient for external automated material handling equipment to automatically pick up the product after injection molding.

[0025] In this embodiment, the injection unit 1 includes an injection cylinder 13 and a seat cylinder 14 located on one side of the injection cylinder 13. The injection cylinder 13 and the seat cylinder 14 are located above the positioning plate 11. The outer wall of the cylinder body of the injection cylinder 13 is fixedly connected to a connecting seat 131. One end of the cylinder body of the seat cylinder 14 is fixedly set on the top of the connecting seat 131 and its output shaft is fixedly connected to the upper end face of the positioning plate 11. The cylinder body of the injection cylinder 13 is connected to the vertical barrel 12 through an adapter seat 101. When the seat cylinder 14 moves, it will drive the injection cylinder 13 to move up and down as a whole. When the injection cylinder 13 moves up and down as a whole, it can drive the vertical barrel 12 to move up and down. The seat cylinder 14 is installed in an inverted manner, so that the vertical barrel 12 protrudes a greater distance from the fixing plate 2, so that the nozzle of the vertical barrel 12 contacts the installed mold gate during injection.

[0026] In this embodiment, template 2 9 and reinforcing seat 7 are also included. Template 2 9 and template 1 8 are respectively used to install the moving mold or the fixed mold on the mold. For example, when template 1 8 is used to install the fixed mold, template 2 9 is used to install the moving mold. Reinforcing seat 7 is fixedly set on the top of template 2 9. The top of reinforcing seat 7 is provided with a sliding shaft 71 and a side cylinder 72. Specifically, a guide sleeve can be welded to the top of reinforcing seat 7 and fitted outside the sliding shaft 71. The bottom of the cylinder body of the side cylinder 72 is fixedly connected to the reinforcing seat 7, and its output shaft is fixedly connected to one end of the sliding shaft 71. The side cylinder 72 provides driving force to the sliding of the sliding shaft 71. One end of the support plate 3 is provided with a limiting groove 33 that is inserted and matched with the other end of the sliding shaft 71. When one end of the sliding shaft 71 is inserted into the limiting groove 33, the strength of the entire support plate 3 against bending deformation is improved, thereby ensuring the accuracy of the vertical barrel 12 and the gate docking.

[0027] Furthermore, one end of the reinforcing seat 7 is flush with the mounting surface of the template 2 9, which also has the advantage of facilitating material handling by automated equipment.

[0028] Working principle: During injection molding, the mold is closed, then the sliding cylinder 4 is moved, the support plate 3 is moved horizontally and the vertical barrel 12 is positioned above the mold gate. Then the side cylinder 72 is moved, the sliding shaft 71 is inserted into the limiting groove 33, then the seat cylinder 14 is started, the seat cylinder 14 drives the vertical barrel 12 downward through the injection cylinder 13 and connects with the gate. Then the hydraulic motor on the injection part 1 is controlled to complete the feeding and rotation action. Finally, the injection cylinder 13 is controlled to inject the material. After the casting is completed, the vertical barrel 12 is raised and reset, the injection cylinder 13 is released, then the support plate 3 is moved horizontally away from the mold, then the sliding shaft 71 is reset, then the entire mold is separated, and finally the external automated material handling equipment is controlled to automatically pick up the material.

[0029] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
