Description
Technical Field
The utility model belongs to the technical field of silicone rubber storage, and particularly relates to a silicone rubber extrusion device.
Background
The silicon rubber is firstly synthesized by taking ferric trichloride as a catalyst, and has better heat resistance, electrical insulation, chemical stability and the like than other common rubbers due to the unique molecular structure. The conventional silicon rubber raw material exists in a liquid state, is packaged by a container and then extruded for use, and then is shaped and molded through a die or other bonding requirements. However, the existing liquid silicone rubber often remains attached to the inner wall of the extrusion nozzle due to the influence of its own viscosity, and the residues are accumulated and solidified to block the nozzle and affect the normal extrusion function, and are not easy to be removed and peeled off due to the adhesion to the inner wall, so a new technical solution is needed to solve the problems.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects in the prior art, the utility model provides a silicone rubber extrusion device which is used for stably extruding a silicone rubber liquid product for a long time.
The utility model is implemented by the following technical scheme: a silicon rubber extrusion device comprises a sleeve, a container, a piston, a pressure rod and a gland. The sleeve is a hollow cylinder, one end of the sleeve is sleeved inside the end of the container, the other end of the sleeve is provided with a notch groove, and the outer edge of the notch groove is provided with a material guide plate; the piston is installed in the inner wall of the sleeve in a fitting mode, the pressure rod is installed on one side, facing the outer side, of the piston, and the gland with the outer diameter larger than the inner diameter of the sleeve is installed at the end of the pressure rod.
Furthermore, the inner wall of the end head of the sleeve facing to the outside is provided with a limiting table.
Further, the container is a soft shell container for storing liquid silicon rubber.
Further, the sum of the thickness of the piston and the length of the pressure rod is equal to the length of the sleeve.
Furthermore, an acute angle included angle between the material guide plate and the center line of the sleeve is 60-80 degrees.
The utility model has the beneficial effects that: utilize piston and telescopic structural design to replace the tradition to extrude the shower nozzle, make liquid silicone rubber spill over along breach groove and stock guide after being extruded, later promote the depression bar make the piston scrape into the container with the adnexed remaining silicone rubber of sleeve inner wall in, avoid the solidification of residue, the part of whole in-process inner wall silicone rubber and external air contact is few, only accomplish the solidification in the position of extruding the stock guide, inner wall residue is promptly by the piston automatic container of impressing promptly afterwards, and the remaining easy cleanness of external stock guide strikes off, with this guarantee that the sleeve can not take place to pile up the jam after long-term the use, improve silicone rubber extrusion device's life-span and durability.

Detailed Description
The utility model is further described with reference to the drawings and examples.
As shown in fig. 1-2, a silicone rubber extrusion device comprises a sleeve 1, a piston 3, a pressure rod 4 and a gland 5. The sleeve 1 is a hollow cylinder, one end of the sleeve is sleeved in the port of a soft shell container 2 with liquid silicon rubber, the other end of the sleeve is provided with a notch groove 1a, the outer edge of the notch groove 1a is provided with a material guide plate 1b, and the inner wall of the end of the sleeve 1 facing outwards is provided with a limiting table 1 c; the piston 3 is mounted on the inner wall of the sleeve 1 in a fitting mode, the pressure rod 4 is mounted on one side, facing the outer side, of the piston 3, and the gland 5 with the outer diameter larger than the inner diameter of the sleeve 1 is mounted at the end of the pressure rod 4. In the design size, the sum of the thickness of the piston 3 and the length of the pressure lever 4 is equal to the length of the sleeve 1, so that when the piston 3 slides to the end head at the inner end of the sleeve 1, the pressure lever 4 can just abut against the end head at the other end of the sleeve 1; in order to ensure that the liquid silicon rubber is not easy to adhere to the outer wall of the sleeve 1 when being discharged, the fixed angle of the material guide plate 1b is designed to be 70 degrees relative to the acute angle of the central line of the sleeve 1.
As shown in figure 3, when the utility model is used, a soft shell of a container 2 is squeezed by hands or tools, so that liquid silicon rubber in an inner cavity of the soft shell is extruded out, a piston 3 is pushed to slide rightwards (the direction is according to figure 3) until the piston abuts against a right limit table 1c, and at the moment, part of the liquid silicon rubber flows out along a notch groove 1a and a material guide plate 1b and is dripped into a part of a device to be bonded or shaped. Then, the pressing cover 5 is pushed from the outer side to enable the connected pressing rod 4 to abut against the piston 3 and slide leftwards until the pressing cover 5 abuts against the outer end face of the sleeve 1, and meanwhile, the piston 3 also moves to the deepest part of the port of the container 2; during the left movement of the piston 3, the residual silicone rubber on the inner wall of the sleeve 1 is scraped and pushed back to the inner cavity of the container 2 in a centralized manner, so that the closed state shown in fig. 4 is formed. Due to the deformability of the soft shell of the container 2, the volume of the inner chamber changes with the movement of the piston 3, maintaining a low gas content of the inner chamber space. And finally, cleaning and scraping the residual adhered substances on the inclined surface of the material guide plate 1b, so as to ensure that the inner wall of the sleeve 1 is not influenced by the silicon rubber and the cured substances thereof, and prolong the service life of the extrusion device.
Specific embodiments of the present invention have been described above with reference to the accompanying drawings. However, it will be understood by those skilled in the art that various changes and substitutions may be made to the embodiments of the present invention without departing from the spirit and scope of the utility model, which is defined by the claims.
