Technical Field

[0001] This application relates to the field of injection molding machine technology, and in particular to an installation structure for an injection molding machine melt cylinder. Background Technology

[0002] The plasticizing unit is one of the most important components in an injection molding machine, responsible for melting and controlling the injection molding compound. The securing of the melt cylinder assembly is particularly crucial, as it is a frequently replaced component during use. Therefore, its securing needs to be convenient, quick, and securely reliable. Traditional layouts have the following drawbacks: existing melt cylinders are generally fixed to the front end of the melt assembly using flanges, resulting in a large space requirement, which in turn hinders the overall coordination of the injection unit structure and leads to low space utilization and insufficient space efficiency. Therefore, this paper proposes a new installation structure for the injection molding machine melt cylinder to address these technical problems. Utility Model Content

[0003] One of the objectives of this application is to provide an installation structure for the melt cylinder of an injection molding machine.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows: an installation structure for a melt cylinder of an injection molding machine, including a head plate assembly, a melt cylinder body, and a snap-fit ​​assembly, wherein the snap-fit ​​assembly is installed on the head plate assembly and cooperates with the melt cylinder body; during installation, the melt cylinder body is adapted to be inserted into the front end of the head plate assembly, and the snap-fit ​​assembly is adapted to lock the melt cylinder body.

[0020] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0021] In the description of this application, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this application.

[0022] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0023] One preferred embodiment of this application, such as Figures 1 to 5 As shown, an installation structure for a melt cylinder of an injection molding machine includes a headplate assembly 1, a melt cylinder body 2, and a locking assembly. The locking assembly is installed on the headplate assembly 1 and cooperates with the melt cylinder body 2. It is understood that during installation, the melt cylinder body 2 can be inserted into the front end of the headplate assembly 1, and then the locking assembly can lock the melt cylinder body 2 in place.

[0024] Therefore, it can be seen that the melt cylinder body 2 is inserted into the head plate assembly 1 during installation. This allows the head plate assembly 1 to also limit the movement of the melt cylinder body 2. Furthermore, the inserted portion reduces the length space occupied, improving space utilization and making the overall structure of the injection molding machine more compact and coordinated. In addition, the snap-fit ​​assembly limits and locks the inserted melt cylinder body 2, eliminating the need to weld flange mounting parts onto the melt cylinder body 2, making its structure lighter and simpler.

[0025] As a further description of the above embodiments: as Figure 1 and Figure 4 As shown, the snap-fit ​​assembly includes a first snap-fit ​​group 3 and a second snap-fit ​​group 4. The first snap-fit ​​group 3 can axially lock the glue cylinder body 2, and the second snap-fit ​​group 4 can circumferentially lock the glue cylinder body 2, thereby achieving dual limiting and locking of the glue cylinder body 2. This ensures the installation stability of the glue cylinder body 2 on the head plate assembly 1.

[0026] This application does not specifically limit the structure of the two decks; the following are specific embodiments for reference:

[0027] like Figure 3 As shown, the first locking assembly 3 includes a retaining ring 301, and an annular groove 5 is provided on the outside of the melt cylinder body 2. It can be understood that during installation, the retaining ring 301 is precisely engaged in the annular groove 5, and then the retaining ring 301 can be fixedly installed on the head plate assembly 1 with (hex socket) screws. In this way, the axial limiting and locking of the melt cylinder body 2 can be achieved through the cooperation between the retaining ring 301 and the annular groove 5.

[0028] Based on the above embodiments, it should be understood that since the retaining ring 301 and the annular groove 5 are circular structures, their engagement makes subsequent disassembly and assembly inconvenient. Therefore, the retaining ring 301 can be configured as follows: Figure 3 As shown, it includes a pair of clamping half-rings 3011, that is, the retaining ring 301 can be installed separately as two clamping half-rings 3011 during installation. This ensures that the axial limit and locking of the melt cylinder body 2 is achieved after installation, and the retaining ring 301 can also be separated from the annular groove 5 after disassembly, which facilitates replacement in the future if damaged.

[0029] like Figure 4 As shown, the second locking assembly 4 includes a cylindrical pin 401, which is disposed on the outside of the glue-melting cylinder body 2. A slot 6 is provided at the front end of the headplate assembly 1. It can be understood that when the glue-melting cylinder body 2 is inserted into the front end of the headplate assembly 1, the cylindrical pin 401 and the slot 6 correspond perfectly, thereby achieving circumferential locking of the glue-melting cylinder body 2. That is, the glue-melting cylinder body 2 cannot rotate in the circumferential direction, ensuring the stability of the glue-melting cylinder body 2 during use. Furthermore, this locking method requires no complicated installation steps; simply inserting the glue-melting cylinder body 2 into the headplate assembly 1 is sufficient, making it simple and convenient.

[0030] In one embodiment of this application, such as Figure 2 As shown, the injection head plate assembly 1 includes an injection head plate 101 and a melt cylinder receiving seat 102. The melt cylinder receiving seat 102 is installed on the (front) side of the injection head plate 101, and forms the front end of the aforementioned injection head plate assembly 1. That is, the melt cylinder body 2 is inserted into the melt cylinder receiving seat 102. Specifically, a feed port 8 is provided at the top of the melt cylinder receiving seat 102, and a feed groove 7 corresponding to the feed port 8 is provided on the outside of the melt cylinder body 2. After the melt cylinder body 2 is inserted into place, the feed port 8 and the feed groove 7 are connected, thus enabling the smooth delivery of injection molding raw materials.

[0031] In addition, such as Figure 5As shown, a frustum 10 can be provided at the mounting end of the melt cylinder connector 102, while a circular groove 9 is provided on the side of the injection head plate 101. During the mating installation, the frustum 10 can be precisely engaged within the circular groove 9, further limiting the position of the melt cylinder connector 102 and ensuring the installation stability between the melt cylinder connector 102 and the injection head plate 101. Simultaneously, the engagement between the frustum 10 and the circular groove 9 also serves as a guide, allowing the melt cylinder connector 102 to align with the injection head plate 101 more quickly and accurately during installation, improving installation efficiency. Finally, the two are fixed together using (hex socket) screws.

[0032] Furthermore, such as Figure 5 As shown, the injection head plate 101 has a mounting cavity 11 for rear-mounting the injection power assembly unit. It is understood that in the traditional arrangement, where the melt power assembly unit and injection power assembly unit are positioned, the injection power assembly unit is placed in front and the melt power assembly unit in the rear. This design, however, uses the mounting cavity 11 in the injection head plate 101 to rear-mount the injection power assembly unit, thus placing the melt power assembly unit in front and the injection power assembly unit in the rear. This arrangement makes the overall center of gravity of the injection molding machine more balanced, avoiding the top-heavy problem that may occur in traditional arrangements, and improving the stability of the injection molding machine during operation. At the same time, placing the injection power assembly unit in the rear also makes the overall structure of the injection molding machine more compact, reducing the floor space and improving space utilization. Furthermore, the rear-mounted design of the injection power assembly unit also facilitates maintenance and upkeep, reducing maintenance costs.

[0033] It should be noted that in the field of injection molding machines, melt power unit and injection power unit are public knowledge known to those skilled in the art, and therefore will not be elaborated further.

[0034] In summary, the advantages of this application are as follows: the injection head plate 101 frame structure is simple to process and assemble, reliably fixed, highly interchangeable, and easy to maintain. The traditional method of directly connecting the melt cylinder to the injection head plate 101 via a flange has been eliminated. In this design, it is decomposed into a pair of clamping semi-rings 3011, a melt cylinder connector 102, and other components. In particular, the clamping semi-rings 3011 facilitate the replacement of the melt cylinder body 2 to use different plastic materials, making operation easier in the confined space of the injection molding machine, reducing on-site length space requirements, lowering design costs, and promoting mass production.

[0035] The basic principles, main features, and advantages of this application have been described above. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection claimed by this application is defined by the appended claims and their equivalents.
