Description

Technical Field

[0001] The utility model relates to the technical field of sealing strips, in particular to a composite sealing strip extrusion die. Background Art

[0002] A sealing strip is a product that seals something to make it difficult to open, and plays the role of shock absorption, waterproofing, sound insulation, heat insulation, dustproofing, and fixing. Sealing strips are made of rubber, paper, metal, plastic and other materials, and composite sealing strips require the use of extrusion molds during use.

[0003] According to the Chinese patent with authorized publication number CN215512196U, a composite shielding sealing strip extrusion die is disclosed. By rotating the adjusting block to drive the adjusting rod to rotate, the movable sleeve can be pushed to move toward the inside of the slide groove through the adjusting rod, so that the fixed plate contacts the inner wall of the slide groove, and the fixed plate can be kept stable inside the slide groove through the friction between the fixed plate and the slide groove, so that the movable frame can be fixed. The movable frame is fixed only by the friction between the fixed plate and the slide groove. In actual use, the above scheme has a relatively limited fixing effect on the movable frame, which may cause the movable frame to slide relative to the mold body under the action of other forces, which may cause the injection tube to be unable to be effectively inserted into the injection hole, thereby failing to achieve the expected use effect, reducing the practicality of the existing composite shielding sealing strip extrusion die.

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0031] See also Figures 1 to 4 The utility model provides a technical solution: a composite sealing strip extrusion die, comprising a die body 1, a mounting frame 2 slidably connected to the outside of the die body 1, a connecting seat 4 fixed to the front of the die body 1, a fixing mechanism 200 installed inside the die body 1 for fixing the mounting frame 2, and an injection assembly 300 installed on the outside of the mounting frame 2 for realizing raw material injection;

[0032] Through the coordinated use of the mold body 1, the mounting frame 2, the material guide hole 5, the fixing mechanism 200 and the injection assembly 300, in actual use, after adjusting the position of the raw material injection, the movable frame can be stably and effectively fixed, so that the movable frame is fixed more stably, avoiding the movable frame being fixed only by the friction between the fixed plate and the slide groove, and effectively avoiding the movable frame from sliding relative to the mold body under the action of other forces, ensuring that the movable frame can achieve the expected use effect, and improving the practicability of the composite sealing strip extrusion mold.

[0033] In this embodiment, the fixing mechanism 200 is a structure for fixing the mounting frame 2 .

[0034] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the fixing mechanism 200 includes a connecting and fixing component 201 installed inside the mold body 1 for fixing the mounting frame 2, and a reinforcing component 202 installed outside the connecting and fixing component 201 for making the connecting and fixing component 201 more stably fixed.

[0035] It should be noted that a feed hole 3 is provided on the front of the mold body 1, and a plurality of material guide holes 5 are provided on the outside of the mold body 1, to ensure that the raw materials for the production of the composite sealing strip can be effectively and evenly squeezed out from the feed hole 3 through the coordinated use of the feed hole 3 and the plurality of material guide holes 5, and sealing plugs 6 are inserted into the front and back material guide holes 5 to effectively prevent the raw materials from overflowing from the unused material guide holes 5.

[0036] In this embodiment, the connecting and fixing component 201 is a structure for fixing the mounting frame 2 .

[0037] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the connecting and fixing component 201 includes two fixing rods 2011 slidably connected to the inside of the mounting frame 2, two pulling blocks 2012 respectively fixed to the opposite ends of the two fixing rods 2011, two adjusting grooves 2013 respectively opened on the left and right sides of the mold body 1, an adjusting block 2014 slidably connected to the inside of the adjusting groove 2013, two fixing grooves 2015 respectively opened on the opposite sides of the two adjusting blocks 2014, two fixing cavities 2016 opened in the adjusting block 2014, two trapezoidal blocks 2017 slidably connected to the inside of the fixing groove 2015, four stabilizing rods 2018 respectively fixed to the top of the top trapezoidal block 2017 and the bottom of the bottom trapezoidal block 2017, and four first springs 2019 respectively fixed to the top of the top trapezoidal block 2017 and the bottom of the bottom trapezoidal block 2017.

[0038] It should be noted that the fixing cavity 2016 is connected to the fixing groove 2015, and four installation grooves 20110 are opened inside the mold body 1. The installation groove 20110 is connected to the adjustment groove 2013 to ensure that the stabilizing rod 2018 can be effectively plugged into the installation groove 20110 to achieve fixation.

[0039] In addition, the adjustable distance of the trapezoidal block 2017 in the fixed cavity 2016 is greater than the adjustable distance of the stabilizing rod 2018 inside the mounting groove 20110, and the first spring 2019 is fixed inside the fixed cavity 2016, ensuring that the trapezoidal block 2017 can effectively drive the stabilizing rod 2018 to move so that the stabilizing rod 2018 can be plugged into the mounting groove 20110.

[0040] In this embodiment, the reinforcing component 202 is a structure used to make the connection and fixing component 201 more stable.

[0041] like Figure 1 , Figure 2 and Figure 4 As shown, the reinforcement component 202 includes a fixing screw 2021 threadedly connected to the inside of the pull block 2012, two fixing rings 2022 respectively fixed to the left and right sides of the mold body 1, and two fixing holes 2023 respectively opened on the opposite sides of the two fixing rings 2022.

[0042] It should be noted that the opposite ends of the two fixing rods 2011 successively penetrate the fixing ring 2022, the mounting frame 2, the mold body 1, the adjustment block 2014 and the fixing groove 2015 and extend to the inside of the fixing groove 2015, ensuring that the fixing rods 2011 can push the trapezoidal block 2017 inside the fixing groove 2015.

[0043] In this embodiment, the injection assembly 300 is a structure for implementing raw material injection.

[0044] like Figure 1 and Figure 2 As shown, the injection assembly 300 includes four mounting blocks 301 fixed to the outside of the mounting frame 2, a fixed frame 302 fixed to the side of the mounting block 301 away from the mounting frame 2, a movable plate 303 threadedly connected to the inside of the fixed frame 302, an injection tube head 304 fixed to the inside of the movable plate 303, a feed tube 305 fixed to the side of the injection tube head 304 away from the mold body 1, and a second spring 306 fixed to the side of the movable plate 303 away from the mold body 1.

[0045] It should be noted that the outer diameter of the injection tube head 304 is equal to the diameter of the material guide hole 5, which effectively prevents the raw material from overflowing from the material guide hole 5. The side of the feed tube 305 close to the mold body 1 passes through the fixed frame 302 and extends to the interior of the fixed frame 302 to be fixed to the injection tube head 304, ensuring that the feed tube 305 can transport the raw material to the injection tube head 304.

[0046] The working principle of the above embodiment is:

[0047] When using the device, the user first takes out the sealing plug 6 in the target material guide hole 5, and then moves the mounting frame 2 forward and backward on the outside of the mold body 1 to adjust the mounting frame 2 to the specified position, and then pushes the two pull blocks 2012 to the two sides of the action respectively, driving the fixing rod 2011 to move left and right, so that the fixing rod 2011 enters the fixing groove 2015, thereby squeezing the trapezoidal block 2017 through the fixing rod 2011, so that the trapezoidal block 2017 moves up and down in the fixing groove 2015, thereby driving the stabilizing rod 2018 to move up and down. At this time, the first spring 2019 is in a compressed state, and the stabilizing rod 2018 is plugged into the mounting groove 20110, so that the mounting frame 2011 can be adjusted by the cooperation of the fixing rod 2011 and the stabilizing rod 2018. The mounting frame 2 is stably connected to the mold body 1, and then the fixing screw 2021 is rotated so that the fixing screw 2021 is fixed to the fixing ring 2022 through the fixing hole 2023, thereby fixing the pull block 2012, thereby ensuring the stability of the fixing rod 2011 when it is fixed, and then the feeding tube 305 is rotated to drive the injection tube head 304 and the movable plate 303 to rotate, and the movable plate 303 is threadedly connected to the inside of the fixed frame 302, so that under the action of the thread thrust, the movable plate 303 and the injection tube head 304 are moved inside the fixed frame 302, so that the injection tube head 304 is moved to the material guide hole 5, so that the raw materials for producing the composite sealing strip can be effectively extruded through the coordinated use of the injection tube head 304, the feeding tube 305, the material guide hole 5 and the feed hole 3.

[0048] Compared with the prior art, the composite sealing strip extrusion mold, through the mold body 1, the mounting frame 2, the material guide hole 5, the fixed rod 2011 in the fixing mechanism 200, the trapezoidal block 2017, the first spring 2019, the fixed screw 2021 and the fixed frame 302 and the injection tube head 304 in the injection assembly 300, can stably and effectively fix the movable frame in actual use after adjusting the position of the raw material injection, so that the movable frame is fixed more stably, avoiding the movable frame being fixed only by the friction force between the fixed plate and the slide groove, and effectively avoiding the relative sliding of the movable frame with the mold body under the action of other forces, ensuring that the movable frame can achieve the expected use effect, improving the practicability of the composite sealing strip extrusion mold, and solving the problem of low practicability of the existing composite shielding sealing strip extrusion mold.
