Description

Technical Field

[0001] The present invention relates to the technical field of vulcanization equipment, in particular to a heat dissipation nozzle and an injection vulcanizer. Background Art

[0002] Compared with traditional compression vulcanizers, rubber injection vulcanizers have the advantages of high vulcanization efficiency and high degree of automation, and have been widely used in the production of rubber products.

[0003] A rubber injection curing machine injects the rubber compound to be formed into the mold cavity through a nozzle, thereby vulcanizing and molding the rubber product. While rubber flows better at high temperatures, making it easier to fill the mold cavity, excessively high temperatures can cause the rubber to prematurely vulcanize and burn. In a relatively closed environment, the nozzle heats up quickly and dissipates heat slowly. A rapid increase in nozzle temperature can cause the rubber compound at the nozzle to burn. Injecting burnt rubber into the mold cavity can result in substandard products, thus impacting the quality of the rubber injection curing machine. Summary of the Invention

[0004] In response to the deficiencies in the prior art, the present application provides a heat dissipation nozzle and an injection vulcanizer. The heat dissipation nozzle can prevent the rubber from burning at the nozzle of the injection vulcanizer, thereby improving the product quality of the rubber injection vulcanizer.

[0005] To achieve the above-mentioned purpose, the present application provides a heat dissipation nozzle having a feeding channel connected to a feeding pipe, wherein the heat dissipation nozzle includes a nozzle barrel and a heat dissipation component;

[0006] The heat dissipation component is connected to the outer side of the nozzle barrel, and the heat dissipation component includes an inner wall, an outer wall, a heat dissipation member and an air inlet, and the inner wall and the outer wall form an annular space;

[0010] Optionally, the top end surface of the outer side wall is lower than the top end surface of the heat dissipation grille and the top end surface of the inner side wall, so as to form an overflow step to increase the air outlet area.

[0011] Optionally, the inner side wall is arranged at an angle to the axial direction of the nozzle barrel, and the heat dissipation channel is arranged at an angle to the axial direction of the nozzle barrel to prevent heated air from directly blowing onto the nozzle barrel.

[0012] Optionally, the heat dissipation nozzle is provided with at least one temperature measuring channel, which connects the outer wall and the nozzle barrel; a temperature sensor is installed in the temperature measuring channel, and the temperature sensor is used to detect the temperature of the rubber in the nozzle barrel.

[0013] Optionally, the outer side wall is provided with a wire groove, which is connected to the temperature measurement channel and is used for wiring the temperature sensor.

[0020] Compared to the prior art, the embodiments of the present application utilize a heat dissipation nozzle.

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0029] In order to prevent the rubber from burning at the nozzle of the injection vulcanizer, the present application provides a heat dissipation nozzle 100, having a feed channel 112, connected to a feed pipe 200, including a nozzle barrel 110 and a heat dissipation component 120; the heat dissipation component 120 is connected to the outside of the nozzle barrel 110, and the heat dissipation component 120 includes an inner wall 124, an outer wall 125, a heat dissipation component and an air inlet 123, and the inner wall 124 and the outer wall 125 form an annular space; the heat dissipation component is arranged in the annular space and divides the annular space into multiple heat dissipation channels; the heat dissipation channel is connected to the air inlet 123 and the outside of the heat dissipation nozzle 100.

[0030] Reference Figure 1 and Figure 2 The heat dissipation nozzle 100 includes a nozzle barrel 110 and a heat dissipation component 120. The nozzle barrel 110 has a feed channel 112. The inner wall 124 and the outer wall 125 of the heat dissipation component 120 form a semi-enclosed annular space. In this embodiment, the heat dissipation component can be a heat dissipation grid 122. The heat dissipation grid 122 is arranged on the air outlet side of the annular space, dividing the air outlet side of the annular space into multiple heat dissipation channels, thereby increasing the heat dissipation area of ​​the nozzle and improving the heat dissipation efficiency. The air inlet side of the annular space is an air channel 127. The air inlet side is provided with an air inlet 123, and the air inlet 123 and the air channel 127 are connected to the heat dissipation channel in sequence. When the nozzle temperature exceeds the limit, compressed air is introduced into the air inlet 123. The compressed air passes through the air channel 127 and then flows through each heat dissipation channel, thereby removing the heat from the nozzle to quickly dissipate heat and reduce the nozzle temperature.

[0031] Furthermore, the heat dissipation component includes a heat dissipation grille 122, which is arranged on the air outlet side of the annular space, and the air inlet side of the annular space is an air channel 127, and the air channel 127 is connected to the air inlet 123; or, the heat dissipation component is a spiral grid, and the heat dissipation channel is a spiral channel.

[0032] Specifically, the heat dissipation member may be the heat dissipation grating 122 described above, which cooperates with the air channel 127 to form a heat dissipation channel. In a feasible embodiment, the heat dissipation member may also be a spiral grid, which divides the annular space into one or more spiral channels. The bottom side of the spiral channel is connected to the air inlet 123, and the other end is connected to the outside. The heat dissipation channel is a spiral channel. The spiral grid increases the heat dissipation area, and the heat dissipation of the spiral grid is accelerated by ventilation.

[0033] Furthermore, the top end surface of the outer side wall 125 is lower than the top end surface of the heat dissipation grille 122 and the top end surface of the inner side wall 124 to form an overflow step to increase the air outlet area.

[0034] like Figure 2 As shown, the top end surface of the outer wall 125 of the heat dissipation component 120 is lower than the top end surface of the heat dissipation grid 122 and the top end surface of the inner wall 124, thereby forming an air outlet section shaped like a step, increasing the air outlet area, and facilitating the heated air passing through the heat dissipation channel to diffuse to the surroundings of the heat dissipation nozzle 100.

[0035] Furthermore, the inner side wall 124 is arranged at an angle to the axial direction of the nozzle barrel 110 , and the heat dissipation channel is arranged at an angle to the axial direction of the nozzle barrel 110 to prevent heated air from directly blowing onto the nozzle barrel 110 .

[0036] For example, Figure 2 As shown, the inner wall 124 of the above-mentioned heat dissipation component 120 is set at an angle with the axial direction of the nozzle barrel 110, that is, the thickness of the inner wall 124 on the air outlet side is greater than the thickness on the air inlet side. In this way, the heat dissipation channel is also set at an angle with the axial direction of the nozzle barrel 110, so that when compressed air is introduced, the air outlet angle of the heated air is at an angle with the axial direction of the nozzle barrel 110, preventing the heated air from secondary heating the nozzle and the feed pipe 200, and facilitating heat dissipation to the surrounding areas of the nozzle.

[0037] Optionally, the heat dissipation nozzle 100 is provided with at least one temperature measuring channel 130 , which connects the outer wall 125 and the nozzle barrel 110 ; a temperature sensor 131 is installed in the temperature measuring channel 130 , and the temperature sensor 131 is used to detect the temperature of the rubber in the nozzle barrel 110 .

[0038] Furthermore, the outer side wall 125 is provided with a wire groove 121 , and the wire groove 121 is connected to the temperature measurement channel 130 and is used for wiring the temperature sensor 131 .

[0039] It should be noted that if Figure 2 As shown, support ribs 126 are provided within the heat dissipation component 120, and the aforementioned temperature measurement channel 130 is located within these ribs. The support ribs 126 also serve to divide the heat dissipation component 120 into sections, each section being equipped with an air inlet 123 and a heat dissipation member. The aforementioned temperature measurement channel 130 is located within the support ribs 126, with an opening formed in the outer wall 125 leading to the nozzle barrel 110, proximate to the feed channel 112. A temperature sensor 131 is installed within the temperature measurement channel 130, which is used to detect the temperature of the rubber material within the feed channel 112 to determine whether the nozzle temperature exceeds a limit. A wire groove 121 is provided at the junction of the outer wall 125 and the support ribs 126, connecting the wire groove 121 to the aforementioned temperature measurement channel 130.

[0040] In a feasible embodiment, the injection molding machine PLC (Programmable Logic Controller) detects the temperature of the heat dissipation nozzle 100 in real time through the temperature sensor 131. If the temperature exceeds the set limit, the air intake valve connected to the air intake port 123 is opened to allow the nozzle to dissipate heat.

[0041] Optionally, the upper side of the nozzle barrel 110 has a thread 111 for connecting to the feeding pipe 200, and the heat dissipation nozzle 100 and the feeding pipe 200 are connected by a threaded connection.

[0042] For example, Figure 1 and Figure 2 As shown, in this embodiment, the nozzle barrel 110 has a thread 111 on its upper side, and the feed pipe 200 of the injection vulcanizer is connected to the heat dissipation nozzle 100 by a threaded connection. It is understood that in other feasible embodiments, the feed pipe 200 and the heat dissipation nozzle 100 can also be connected by other feasible connection methods such as welding.

[0043] Furthermore, the heat dissipation nozzle 100 further includes a heat dissipation copper tube, which is arranged on the outside of the nozzle barrel 110 .

[0044] Specifically, in a feasible embodiment, the heat dissipation nozzle 100 is further provided with a heat dissipation copper tube, which is arranged outside the nozzle barrel 110. One end of the heat dissipation copper tube is connected to the heat dissipation component to further accelerate the heat dissipation of the nozzle.

[0045] Another embodiment of the present application provides an injection vulcanizing machine, referring to Figure 3 , including a heat dissipation fan 300, a ventilation channel 400, a feeding pipe 200 and the heat dissipation nozzle 100 in the aforementioned embodiment.

[0046] Furthermore, the ventilation channel 400 is arranged on both sides of the injection vulcanizer, and the ventilation channel 400 connects the inner cavity 101 of the injection vulcanizer with the outside. The cooling fan 300 is arranged in the ventilation channel 400 for exchanging airflow between the hot air in the inner cavity 101 and the outside.

[0047] For example, if the temperature of the heat dissipation nozzle 100 is detected to exceed a set limit, the heat dissipation nozzle 100 connects to the air inlet 123 and inputs compressed air to dissipate heat from the nozzle. At this point, a large amount of heated air gathers in the injection molding machine's inner cavity 101. The heat dissipation fan 300 and ventilation duct 400 provided within the injection molding machine can promptly expel the heated air and prevent heat accumulation within the inner cavity 101. The PLC can control the opening of the heat dissipation nozzle 100's air inlet 123 and the heat dissipation fan 300 simultaneously or individually as needed.
