Description

Technical Field

[0001] The utility model relates to the technical field of LC modules, and particularly relates to a glue-passing head for drainage. Background Art

[0002] The glue-passing head for drainage is a key component used in specific industrial equipment, especially equipment such as injection molding machines. The glue-passing head for drainage is mainly used in the material pipe assembly of equipment such as injection molding machines to help achieve smooth flow of the rubber material, reduce resistance, and improve production efficiency. The glue-passing head for drainage usually includes a cylinder, a conical part, and a plurality of protruding parts formed by protruding and extending outward from the peripheral wall of the conical part. The design of the conical part enables the rubber material to enter more smoothly, and the notch design on the protruding part reduces the contact area with the glue-passing ring and reduces the friction force. In addition, some glue-passing heads for drainage may also include structures such as arc chamfers to further optimize the fluidity of the rubber material and reduce the adhesion resistance.

[0003] The glue-passing ring on the glue-passing head for drainage is sleeved on the screw. In order for the rubber material to pass through the inner side of the glue-passing ring, there needs to be a certain distance gap between the inner side of the glue-passing ring and the outer surface of the screw. Therefore, the glue-passing ring cannot slide stably and linearly on the screw, and there is also a certain gap between the glue-passing ring located between the rocket head and the check ring. During the operation of the equipment, the glue-passing ring is prone to shaking up and down and generating abnormal noises.

[0004] Therefore, a glue-passing head for drainage is proposed to solve the above problems. Content of the Utility Model

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Embodiment:

[0024] Please refer to Figures 1-3 , this embodiment provides a glue - applying head for drainage, which includes a rocket head 1. One end of the rocket head 1 is fixedly connected to a screw 2. A glue - applying ring 3 is installed on the outer ring surface of the screw 2. A sleeve 31 is installed inside the glue - applying ring 3. The sleeve 31 is slidably sleeved on the outer ring surface of the smooth surface at one end of the screw 2. The length dimension of the sleeve 31 is shorter than the inner length dimension of the glue - applying ring 3. When this drainage glue - applying head is in use, by installing the sleeve 31 inside the glue - applying ring 3 and slidably installing the sleeve 31 on the smooth surface at one end of the screw 2, the glue - applying ring 3 is installed on the screw 2 by using the sleeve 31. During the flow of the rubber material, the sleeve 31 slides linearly left and right on the screw 2, and the glue - applying ring 3 will not make abnormal noises due to shaking on the screw 2 when the glue - applying ring 3 is vibrated because of the gap between the inner side of the glue - applying ring 3 and the screw 2, making the injection - molding equipment operate more stably and quietly.

[0025] In this embodiment, as Figure 3 shown, four support blocks 32 are equidistantly installed on the outer ring surface of the sleeve 31. The outer side surfaces of the support blocks 32 are fixedly connected to the inner side wall of the sleeve 31. One end of the sleeve 31 is flush with one end of the glue - applying ring 3. Therefore, the sleeve 31 can be evenly installed inside the glue - applying ring 3.

[0026] In this embodiment, as Figure 1 and Figure 3As shown, one end of the screw rod 2 is provided with an external thread, and one end of the screw rod 2 is threadedly connected with a check ring 4 and a positioning ring 41, and a sealing gasket 42 is installed on one side of the check ring 4. The sealing gasket 42 can be pressed against the outer side surface of the annular edge plate 33 to play a check role.

[0027] In this embodiment, if Figure 1 , Figure 2 and Figure 3 As shown, the rubber ring 3 is supported by one end of the slide rod 12 in the initial state, so that one side of the annular edge plate 33 on the rubber ring 3 is pressed against the sealing gasket 42 on the check ring 4, and after the annular edge plate 33 is compressed, it will drive the rubber ring 3 to move and squeeze the slide rod 12 into the inner side of the circular hole groove 11. Therefore, when the injection molding equipment stops, the rubber head automatically forms a sealing state to prevent the rubber material from flowing back. There is no need to use reverse extrusion force to form a seal when the rubber material flows back, thereby making the check sealing of the rubber head better.

[0028] Working principle: when the drainage rubber head is in use, when the rubber enters the rubber head through the injection molding machine, the rubber will squeeze the annular plate 33 to make the rubber ring 3 slide in the direction of the rocket head 1. At this time, the slide bar 12 retracts into the circular hole groove 11, and the rubber enters the rocket head through the inner side of the rubber ring 3 for diversion. Since the sleeve 31 is slidably mounted on the smooth surface of one end of the screw 2, the rubber ring 3 is mounted on the screw 2 by the sleeve 31. During the flow of the rubber, the sleeve 31 slides left and right in a straight line on the screw 2. The gap between the inner side of the rubber ring 3 and the screw 2 will not cause the rubber ring 3 to shake on the screw 2 when it is vibrated, thereby generating abnormal noise, making the injection molding equipment run more stably and quietly. At the same time, the rubber ring 3 is supported by one end of the slide bar 12 in the initial state. When the injection molding equipment stops, the rubber head automatically forms a sealed state to prevent the rubber from flowing back. There is no need to use reverse extrusion force to form a seal when the rubber flows back, thereby making the anti-reverse sealing of the rubber head better.

[0029] All technical features in this embodiment can be freely combined according to actual needs.

[0030] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
