Description

Technical Field

[0001] The utility model relates to the technical field of injection molding equipment, and particularly relates to a side die pressing assembly of an injection machine. Background Art

[0002] As the main equipment for rubber product processing, an injection machine usually has a mold clamping mechanism. The mold is installed through the mold clamping mechanism to realize mold clamping and mold opening, so as to meet the injection processing requirements.

[0003] Currently, in the injection machines on the market, in order to improve processing efficiency and reduce manufacturing costs, the mold is usually set to at least three layers, including a bottom mold, an intermediate mold, and a top mold. At this time, the bottom mold and the top mold are respectively installed on the corresponding structures of the mold clamping mechanism, while the intermediate mold is movably arranged between the bottom mold and the top mold. A processing cavity is formed by the bottom mold and the intermediate mold, and another processing cavity is formed by the intermediate mold and the top mold, so as to realize the injection processing of at least two sets of products at the same time. However, the existing mold clamping mechanism of the injection machine usually only includes an external frame and an upper telescopic driver. During installation, the external frame is placed vertically, and the upper telescopic driver is installed on the upper part of the external frame. In addition, the bottom mold of the mold is installed on the external frame, the top mold is installed on the upper telescopic driver, and the intermediate mold is arranged between the bottom mold and the top mold. During mold clamping, the upper telescopic driver drives the top mold to move towards the bottom mold and the intermediate mold to meet the mold clamping requirements. During mold opening, the upper telescopic device drives the top mold to move upwards away from the bottom mold and the intermediate mold, which is convenient for taking out the obtained products. Although the above mold clamping mechanism can already meet the processing requirements, during actual processing, since the rubber products obtained by processing are easily bonded to the intermediate mold and the top mold after molding, during mold opening, the intermediate mold is likely to move upwards with the top mold, and there is a problem that the intermediate mold accidentally drops during the rising process, which poses a great safety hazard and threatens the personal safety of the operator, and is not conducive to the popularization and application of the injection machine. Summary of the Invention

[0004] Aiming at the above problems existing in the prior art, the present invention aims to provide a side die pressing assembly of an injection machine, in which a telescopic mechanism is arranged on the outer side of the external frame, a slideway communicating with its processing inner cavity is opened on the external frame, and a die pressing member extending through the slideway to the processing inner cavity of the external frame is arranged on the telescopic mechanism. When the intermediate mold accidentally moves upwards with the top mold, the telescopic mechanism can drive the die pressing member to move downwards to press the intermediate mold, thereby preventing the intermediate mold from moving upwards with the top mold and causing subsequent safety hazards of accidental dropping, with higher safety guarantee and being conducive to the popularization and application of the injection machine.

The strengthening seat is installed at intervals above or below the fixed seat and on the external frame. The end of the guiding rod away from the connection with the fixed seat is installed on the strengthening seat.

[0012] For the above-mentioned lateral die pressing assembly of an injection machine, it further includes a stroke monitoring mechanism.

[0021] Figure 1 It is a structural diagram of one perspective of an embodiment of the lateral die pressing assembly of an injection machine according to the present utility model; Figure 2 It is a structural diagram of another perspective of an embodiment of the lateral die pressing assembly of an injection machine according to the present utility model;Figure 3 This is a structural diagram of another perspective of an embodiment of the lateral die pressing assembly of an injection machine according to the present utility model. As Figure 1 , Figure 2 and Figure 3 shown, the lateral die pressing assembly of the injection machine provided in this embodiment is installed on the outer frame 5 of the injection machine. At this time, a processing inner cavity is provided on the outer frame 5. The mold clamping mechanism is installed on the outer frame 5, and the mold is installed in the processing inner cavity, which is convenient for processing operations. Moreover, the lateral die pressing assembly provided in this embodiment is arranged on the outer side of the outer frame 5 and beside the processing inner cavity, so that the lateral die pressing assembly does not occupy too much space in the processing inner cavity of the outer frame 5, avoiding the problem that increasing the structure of the outer frame 5 is required due to excessive occupation of the space in the processing inner cavity. In addition, it also enables the lateral die pressing assembly to correspond to the intermediate mold in the processing inner cavity later, and the structural design is more reasonable.

[0022] Specifically, the lateral die pressing assembly of the injection machine provided in this embodiment includes a fixed seat 1, a telescopic mechanism 2, and a die pressing member 3. During installation, the fixed seat 1 is fixedly installed on the outer frame 5. At the same time, the telescopic mechanism 2 is installed on the fixed seat 1, so that the fixed seat 1 can serve as the installation carrier of the telescopic mechanism 2, realizing the stable installation of the telescopic mechanism 2 on the outer frame 5. At the same time, the telescopic shaft of the telescopic mechanism 2 is arranged in the vertical direction, so that the intermediate mold can be pressed down by the telescopic mechanism 2 later to prevent the problem that the intermediate mold is lifted by the top mold. At this time, the die pressing member 3 further includes a connecting rod 31 and a pressing block 32. Moreover, a slideway 51 communicating with the processing inner cavity is opened on the side wall of the outer frame 5 where the die pressing assembly is installed, and the slideway 51 is strip-shaped and arranged in the vertical direction, so that the arrangement direction of the slideway 51 is consistent with the movement direction of the telescopic shaft of the telescopic mechanism 2, and at the same time, it can also meet the use requirements of pressing down the intermediate mold. During installation, the connecting rod 31 is inserted into the corresponding slideway 51, so that the connecting rod 31 can move up and down in the corresponding slideway 51. At the same time, one end of the connecting rod 31 is connected to the telescopic shaft of the telescopic mechanism 2, and the other end of the connecting rod 31 extends into the processing inner cavity and is installed with a pressing block 32. The connecting rod 31 is used to connect the telescopic mechanism 2 and the pressing block 32 located on the outer side and the inner side of the outer frame 5 respectively, so that the telescopic shaft of the telescopic mechanism 2 can drive the pressing block 32 to move in the vertical direction through the connecting rod 31, so as to press down the intermediate mold during mold opening, ensuring that the intermediate mold will not accidentally fall due to following the top mold moving up, and the safety guarantee is higher.

[0023] More specifically, there are two groups of lateral compression mold assemblies arranged on the external frame 5. During installation, the two groups of lateral compression mold assemblies are symmetrically distributed on both sides of the external frame 5. At the same time, the two groups of lateral compression mold assemblies are respectively located on both sides of the mold, so that there are corresponding lateral compression mold assemblies on both sides of the mold to press down the middle mold, ensuring that the middle mold is subjected to uniform force, thereby improving the stability when pressing down the middle mold and further improving the safety performance.

[0024] More specifically, the telescopic mechanism 2 for driving the pressing mold 3 to move includes a telescopic driver 21 and a slider 22. During installation, the telescopic driver 21 is installed on the fixing seat 1 in the vertical direction. At the same time, the telescopic shaft of the telescopic driver 21 is arranged in the vertical direction to ensure that the intermediate mold can be pressed down when the mold is separated later. In addition, the slider 22 is installed on the telescopic shaft of the telescopic driver 21, so that the telescopic shaft of the telescopic driver 21 can drive the slider 22 to move. In addition, the end of the connecting rod 31 away from the pressing block 32 is connected to the slider 22, so that the slider 22 can be used as a transition structure for connecting the connecting rod 31 to the telescopic shaft of the telescopic driver 21, providing a larger installation position for the connection between the connecting rod 31 and the telescopic shaft of the telescopic driver 21, and more convenient for disassembly and assembly.

[0025] More specifically, the telescopic mechanism 2 includes a guide assembly 23 in addition to the telescopic drive 21 and the slider 22. The guide assembly 23 includes a guide rod 231 and a guide sleeve 232. During installation, the guide rod 231 is arranged parallel to and spaced from the telescopic axis of the telescopic drive 21, so that the arrangement direction of the guide rod 231 can be in the same direction as the telescopic axis of the telescopic drive 21, adapting to the movement of the telescopic drive 21, and at the same time, avoiding the interference of the guide rod 231 on the movement of the telescopic drive 21. In addition, one end of the guide rod 231 is fixedly installed on the fixed seat 1, so that the guide rod 231 is stably installed. At the same time, the guide sleeve 232 is installed on the slider 22, and the guide sleeve 232 is sleeved outside the guide rod 231, that is, the slide of the guide sleeve 232 outside the guide rod 231 guides the movement of the slider 22, thereby improving the stability of the slider 22, making the slider 22 more capable of carrying more, and providing conditions for the subsequent stable downward pressing of the intermediate mold.

[0026] More specifically, the telescopic shaft of the telescopic driver 21 is connected to the middle of the slider 22. At the same time, a guide sleeve 232 is provided at both ends of the slider 22. At the same time, each guide sleeve 232 corresponds to a guide rod 231, so that both ends of the slider 22 have a guide assembly 23, so that the slider 22 is more evenly stressed, further improving the stability of the movement of the slider 22, effectively preventing the slider 22 from tilting and getting stuck, and the structural design is more reasonable.

[0027] More specifically, the telescopic mechanism 2 further includes a reinforcing seat 24. At this time, the reinforcing seat 24 is installed at intervals below or above the fixed seat 1, and the reinforcing seat 24 is fixedly installed on the outer frame 5, so that both the fixed seat 1 and the reinforcing seat 24 are fixed on the outer frame 5 and are distributed at intervals up and down. At the same time, the end of the guide rod 231 away from the connection with the fixed seat 1 is installed on the reinforcing seat 24, so that both ends of the guide rod 231 can be connected by the fixed seat 1 and the reinforcing seat 24 respectively, and both ends of the guide rod 231 are fixed, thereby improving the installation stability of the guide rod 231 and further improving the stability of the slider 22, so as to realize the stable pressing down of the intermediate die.

[0028] More specifically, the lateral die pressing assembly provided in this embodiment further includes a stroke monitoring mechanism 4. At this time, the stroke detection mechanism further includes a mounting plate 41, a limit sensor 42 and a trigger piece 43. During installation, the mounting plate 41 is arranged parallel to the telescopic shaft of the telescopic driver 21, and one end of the mounting plate 41 is fixed to the fixed seat 1, and there is a gap between the mounting plate 41 and the slider 22, which can not only enable the mounting plate 41 to adapt to the moving stroke of the telescopic shaft of the telescopic driver 21 and cover the moving direction of the telescopic shaft of the telescopic driver 21, but also avoid interfering with the movement of the slider 22. In addition, two limit sensors 42 are installed on the mounting plate 41 at intervals along its arrangement direction, that is, both limit sensors 42 are arranged in the moving direction of the telescopic shaft of the telescopic driver 21. At the same time, a trigger piece 43 is installed on the slider 22 and moves between the two limit sensors 42. The positions of the trigger piece 43 are detected by the two limit sensors 42 respectively to monitor the position of the slider 22, thereby avoiding the problem of equipment damage caused by excessive telescoping of the telescopic driver 21, and the safety guarantee is higher. It should be noted that the limit sensor 42 can be an existing photoelectric sensor on the market as long as it can meet the monitoring requirements. Therefore, its specific structure and use will not be elaborated here.

[0029] More specifically, a number of connection holes 321 are also formed in the pressing block 32. At the same time, a number of locking holes corresponding to the connection holes 321 are provided on the side of the intermediate die of the mold. During installation, the locking holes and the corresponding connection holes 321 are connected and locked by bolts, realizing the connection between the pressing block 32 and the intermediate die of the mold. When the mold is separated, the lateral die pressing assembly can not only press down the intermediate die, but also control the position of the intermediate die, so as to facilitate the separation of the intermediate die and the bottom die, and thus facilitate the operator to take out the product in the forming cavity between the intermediate die and the bottom die and clean it, and the structural design is more reasonable.

[0030] The side die pressing assembly of the injection machine provided in this embodiment includes a fixed seat 1, a telescopic mechanism 2, and a die pressing member 3. By arranging the fixed seat 1 on the side of the outer frame 5 with a processing inner cavity, installing the telescopic mechanism 2 on the fixed seat 1 and arranging its telescopic shaft in the vertical direction. At the same time, a slideway 51 communicating with the processing inner cavity is opened on the side of the outer frame 5. The connecting rod 31 of the die pressing member 3 is passed through the slideway 51, and one end of the connecting rod 31 is connected to the telescopic shaft of the telescopic mechanism 2, and the other end extends into the processing inner cavity and is installed with a pressing block 32. When the mold in the processing inner cavity is demolded, the telescopic mechanism 2 can drive the pressing block 32 to move downwards to press the intermediate mold of the mold, preventing the safety risk of the intermediate mold rod accidentally falling after following the top mold to move upwards, ensuring that the intermediate mold is stably at a lower position, with higher safety guarantee, and facilitating the popularization and application of the injection machine.

[0031] The above are only the preferred embodiments of the present utility model, and do not limit the implementation manners and protection scope of the present utility model.
