Description

Technical Field

[0001] This utility model belongs to the field of automotive radiator manufacturing technology, and specifically relates to a biting edge structure and a biting edge mold. Background Technology

[0002] In the production of automotive radiators, a crimping process is required for the water chamber and mainboard of the radiator. However, existing crimping molds have complex structures, and the ends of the crimping blocks are prone to breakage during the mold closing process between the upper and lower molds. Utility Model Content

[0003] The purpose of this utility model is to provide a biting edge structure and a biting edge mold to solve one or more technical problems existing in the prior art.

[0004] The technical solution adopted to solve the above-mentioned technical problems is as follows: This utility model discloses a biting edge structure applied in a biting edge mold. The biting edge mold includes a push block connected to an upper mold. The biting edge structure includes a core guide seat and biting teeth. The biting teeth include a biting end and a pressing end arranged opposite to each other along a first direction. The bottom surface of the biting teeth is provided with a protruding support member. The biting teeth are configured such that when the push block abuts against the pressing end, the biting teeth move relative to the core guide seat along the first direction, and the biting end tilts upward with the support member as a fulcrum.

[0005] The present invention has at least the following beneficial effects: by replacing the existing pin structure with a support member, when the push block of the upper mold abuts against the pressing end of the bite teeth, the bite teeth move relative to the core guide seat in the first direction and approach the bite edge position. At the same time, the pressing end is also pressed down by the push block. At this time, the bite teeth automatically drive the bite end to tilt upward with the support member as the fulcrum, so that the bite end is located at the upper end of the required bite position of the radiator water chamber and the radiator main board. When the upper mold and the lower mold of the bite edge mold are closed, the bite end is driven down by the upper mold to complete the bite edge process.

[0006] In this way, the number of components that make up the bite edge structure is reduced, the structure is simple, and the volume of the reduced structural components allows for an increase in the thickness of the bite teeth and core guide, thereby improving the rigidity of the bite edge structure without affecting its volume and preventing breakage at the bite end, pressing end, and the end of the core guide.

[0007] As a further improvement to the above technical solution, the core guide seat is connected to a first guide end, and the teeth are connected to a second guide end, and the first guide end and the second guide end slide relative to each other along a first direction.

[0008] As a further improvement to the above technical solution, the first guide end is a toothed pressing block, and the second guide end is a guide groove extending along the first direction, with the toothed pressing block embedded in the guide groove.

[0009] As a further improvement to the above technical solution, the bite tooth is provided with a reset cavity, and a first elastic element is provided in the reset cavity and extended and retracted along a first direction. The first elastic element abuts against the core guide seat and the bite tooth respectively.

[0010] As a further improvement to the above technical solution, the core guide seat is provided with a mounting cavity, and a second elastic element is provided in the mounting cavity, which is extended and retracted in the vertical direction. The second elastic element abuts against the core guide seat and the bite teeth respectively.

[0011] As a further improvement to the above technical solution, the reset cavity is located at one end of the bite tooth with the biting end, the mounting cavity is located at one end of the core guide near the biting end, and the support member is located at one end of the bite tooth with the pressing end.

[0012] As a further improvement to the above technical solution, the core guide seat is provided with a limiting groove, the biting teeth move in the limiting groove along the first direction, and the limiting groove is connected to the mounting cavity.

[0013] As a further improvement to the above technical solution, the first elastic element is a first spring, and the second elastic element is a second spring and a round steel ball.

[0014] As a further improvement to the above technical solution, the bite block and the core guide seat are connected by a connecting pin.

[0015] This utility model also discloses a bite-edge mold, including an upper mold, a lower mold, and the bite-edge structure described in any one of the above.

[0016] The present invention has at least the following beneficial effects: by simplifying the bite structure through the support member, the installation volume of the bite structure is freed up so that the thickness of the bite teeth and core guide seat can be increased, thereby increasing the structural rigidity of the bite structure and extending the service life of the bite structure and the bite mold.

[0019] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] In the description of this utility model, the use of terms such as "several" means one or more, with "multiple" meaning two or more. Terms like "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number.

[0022] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0023] In related technologies, refer to Figure 1 The existing mold structure 100 includes a base 110, a slider 120, a pin 130, and a bite block 140. The base 110 and slider 120 are slidably connected. The slider 120 is hinged to the bite block 140 via the pin 130. The upper mold's inclined block abuts against the slider 120, causing the slider 120 and bite block 140 to move closer to the heat sink. The hydraulic end presses down on the bite block 140 to achieve the biting operation. However, in actual application, the end of the bite block 140 and the slider 120 near the pin 130 is prone to breakage, and the end of the bite block 140 performing the biting operation is also prone to breakage.

[0024] Reference Figures 2 to 7 The following are several embodiments of the bite-edge structure and bite-edge mold of this utility model.

[0025] like Figures 2 to 7 As shown, the bite-edge structure 200 of this utility model embodiment is applied to the bite-edge mold 600. Specifically, the bite-edge structure 200 includes a core guide seat 300 and bite teeth 400. The core guide seat 300 is connected to the lower mold of the bite-edge mold 600, and the two are relatively fixed. The bite teeth 400 include a biting end 410 and a pressing end 420 arranged opposite to each other along a first direction. A support member 430 is provided on the bottom surface of the bite teeth 400 facing downward, and the support member 430 protrudes downward from the bottom surface of the bite teeth 400.

[0026] It is understandable that the undercut die 600 includes an upper die, which is connected to a push block 630 and a pressure seat 640, such as... Figure 7 As shown. Thus, when the upper and lower molds are closed relative to each other, the push block 630 moves downward relative to the bite tooth 400 and abuts against the pressing end 420. The push block 630 forces the bite tooth 400 to move relative to the core guide seat 300 in the first direction, so that the bite tooth 400 moves in the direction of the biting end 410. At this time, the bite tooth 400 uses the protruding support member 430 as the fulcrum, and the push block 630 abuts against the pressing end 420, so that the biting end 410 can be slightly tilted upward. The pressing seat 640 is vertically opposite to the biting end 410, and the pressing seat 640 abuts against the biting end 410 from top to bottom, thereby realizing the pressing of the biting end 410 and completing the biting edge of the radiator main board 680 and the water chamber.

[0027] With this design, the number of components that make up the bite edge structure 200 is reduced, the structure is simplified, the thickness of the bite teeth 400 can be increased, the structural rigidity of the bite teeth 400 is increased, and the bite teeth 400 are prevented from breaking.

[0028] In this embodiment, the first direction is the left-right direction.

[0029] Understandably, the core guide seat 300 is connected to the first guide end, and the bite tooth 400 is connected to the second guide end. The first guide end and the second guide end slide relative to each other in the first direction to guide the movement of the bite tooth 400 caused by the push block 630 abutting against the pressing end 420, so as to avoid the bite tooth 400 from deviating and affecting the bite quality of the heat sink.

[0030] In some embodiments, the first guide end can be a slide block and the second guide end can be a slide rail, thereby enabling the teeth 400 and the core guide block 300 to move along the first direction.

[0031] In this embodiment, the first guide end is a toothed pressure block 310, which is fixedly connected to the core guide seat 300, such as... Figure 2 , Figure 3 and Figure 5 As shown. The second guide end is a guide groove 440, as... Figure 3 and Figure 5 As shown, the guide groove 440 extends along the first direction, and the toothed pressing block 310 is embedded in the guide groove 440. Thus, when the toothed 400 moves relative to the core guide seat 300, the toothed pressing block 310 moves relative to the guide groove 440 along the extension direction of the guide groove 440, ensuring that the toothed 400 and the core guide seat 300 move relative to each other in the left and right directions. Furthermore, while ensuring the movement guidance, it does not interfere with the upward or downward tilting of the toothed 400 with the support member 430 as the fulcrum.

[0032] In some embodiments, the bite block 310 and the core guide seat 300 can be connected and fixed by means of bolts, screws or welding.

[0033] In this embodiment, the bite block 310 and the core guide seat 300 are connected by a connecting pin 500, such as... Figure 3 , Figure 5 and Figure 7 As shown, the connecting pin 500 is a cylindrical pin. Both the toothed pressure block 310 and the core guide seat 300 have corresponding upper and lower holes 360, as shown... Figure 3 and Figure 5 As shown, the connecting pin 500 is interference-fitted into the hole 360, or the connecting pin 500 is threaded into the hole 360, thereby achieving a fixed connection between the toothed pressure block 310 and the core guide seat 300.

[0034] It is understandable that the hollow tooth 400 forms a reset cavity 450, such as Figure 4As shown, a first elastic element is provided in the reset cavity 450. The reset cavity 450 extends along the first direction. The first elastic element is telescopically arranged along the first direction. One end of the first elastic element extends out of the reset cavity 450 and abuts against the core guide seat 300. The other end of the first elastic element abuts against the bite tooth 400, that is, abuts against the inner wall surface of the reset cavity 450 along the extension direction.

[0035] Thus, when the upper and lower molds are closed, the push block 630 abuts against the pressing end 420, and the bite teeth 400 move relative to the core guide seat 300 in the first direction. At this time, the first elastic element is in a stretched or compressed state. When the upper and lower molds are separated, the elastic potential energy stored in the first elastic element forces the bite teeth 400 to move in the opposite direction, thereby enabling the heat sink structure to be quickly released after the biting process is completed. This facilitates the quick removal and reinsertion of the heat sink structure to be bitten, improving the production efficiency of the biting structure 200.

[0036] In this embodiment, the reset cavity 450 and the first elastic element are both located at the end of the bite tooth 400 with the biting end 410. When the upper mold and the lower mold are closed, the first elastic element is in a compressed state.

[0037] In this embodiment, the first elastic element is a helically arranged first spring 460, such as... Figure 4 As shown.

[0038] It is understandable that the core guide seat 300 has a hollow cavity 320, such as... Figure 6 As shown, a second elastic element is provided in the mounting cavity 320. The mounting cavity 320 extends in the vertical direction, and the second elastic element is extended and retracted in the vertical direction. One end of the second elastic element extends out of the mounting cavity 320 and abuts against the bite tooth 400, and the other end of the second elastic element abuts against the core guide seat 300.

[0039] Thus, the second elastic element can support one end of the tooth 400. Both the mounting cavity 320 and the second elastic element are located at the end of the core guide 300 near the biting end 410. When the upper and lower molds are closed, the pressure seat 640 presses down on the biting end 410. While achieving the biting edge of the radiator structure, the second elastic element compresses and buffers the downward pressure from the pressure seat 640 on the biting end 410, preventing the biting end 410 from directly bearing the impact load of the pressure seat 640 and thus avoiding breakage. When the upper and lower molds separate, the pressure seat 640 moves upward, and the elastic potential energy stored in the second elastic element drives the biting end 410 upward, causing it to tilt upward, facilitating the removal of the bitten radiator structure.

[0040] In this embodiment, the second elastic element is a round steel ball 340 and a second spring 330, such as Figure 6As shown, the round steel ball 340 is located between the bite teeth 400 and the second spring 330, which is a helical spring. The round steel ball 340 can disperse pressure when the second spring 330 is compressed, preventing excessive local stress in the second spring 330 and increasing the load-bearing capacity and durability of the second elastic element. Furthermore, when the second spring 330 is subjected to impact loads, the steel ball rolls and moves relative to the second spring 330, absorbing and dispersing some of the impact energy, enhancing the buffering effect of the second elastic element, and further preventing the bite end 410 from breaking.

[0041] In some embodiments, the end of the second elastic member that abuts against the core guide 300 is the inner wall surface of the mounting cavity 320 along the extending direction.

[0042] In this embodiment, the bottom surface of the core guide seat 300 is connected to the lower mold, and the mounting cavity 320 is connected to the bottom surface of the core guide seat 300. Therefore, the end of the second elastic member that abuts against the core guide seat 300 is the lower mold.

[0043] In this embodiment, the support member 430 is disposed at the end of the bite tooth 400 with the pressing end 420. That is, the distance between the support member 430 and the pressing end 420 along the first direction is smaller than the distance between the support member 430 and the bite end 410 along the first direction. With this arrangement, using the support member 430 as the fulcrum, when the push block 630 abuts against the pressing end 420 downward, even if the downward pressing distance of the pressing end 420 is small, the bite end 410 still has a certain upward tilting distance.

[0044] It is understandable that the core guide seat 300 is provided with a limiting groove 350, such as Figures 2 to 6 As shown, the limiting groove 350 is used to limit the range of motion of the bite tooth 400 along the first direction, so as to avoid the situation where the bite tooth 400 moves a distance in the first direction beyond the biting position of the biting end 410 when the push block 630 abuts against the pressing end 420. It can also prevent the bite tooth 400 from falling off the core guide seat 300 when the first elastic element resets the bite tooth 400.

[0045] In some embodiments, the support member 430 may be a plurality of dot-shaped protrusions, which are spaced apart along the front-rear direction, thereby causing the fulcrum of the bite teeth 400 to extend along the front-rear direction.

[0046] In other embodiments, the support 430 is a strip-shaped protrusion that extends in the front-back direction, so that the fulcrum of the bite tooth 400 extends in the front-back direction, ensuring that the biting end 410 and pressing end 420 of the bite tooth 400 in the left-right direction are raised or pressed down.

[0047] In this embodiment, the support member 430 and the bite teeth 400 are integrally formed.

[0048] Understandably, the side of the pressing end 420 away from the occlusal end 410 has a pressing bevel 421, such as... Figure 4 As shown.

[0049] like Figure 7 As shown, the bite-edge mold 600 of this utility model embodiment includes an upper mold, a lower mold, and a bite-edge structure 200. Specifically, the upper mold includes an upper template 610, a middle template 620, a push block 630, and a pressure seat 640. The upper template 610 and the middle template 620 are connected. The middle template 620 is connected to the push block 630 and the pressure seat 640. The push block 630 has an abutting inclined surface and is vertically opposite to the inclined surface of the pressing end 420. The pressure seat 640 is vertically opposite to the bite end 410. The lower mold includes a lower template 650 and a limiting block 660. The core guide seat 300 and the limiting block 660 are connected to the lower template 650. The limiting block 660 is used to limit the range of the push block 630 to prevent the push block 630 from shifting when it moves down to abut the pressing end 420.

[0050] With this configuration, when the upper and lower molds are closed, the push block 630 presses down, one end of the push block 630 moves down along the limiting block 660, and the other end of the push block 630 abuts against the pressing end 420 of the bite tooth 400, causing the abutting inclined surface and the pressing inclined surface 421 to abut against each other, forcing the bite tooth 400 to move relative to the core guide seat 300 and approach the heat sink structure to be bitten. At this time, because the pressing end 420 is pressed down by the push block 630, the biting end 410 tilts upward with the support member 430 as the fulcrum. As the upper mold continues to press down, the pressure seat 640 abuts against the biting end 410 and drives the biting end 410 to move down, thereby performing the biting operation on the heat sink water chamber 670 and the heat sink main board 680.

[0051] Understandably, the connection structure between the bite structure 200 and the upper and lower dies is simple. The thickened bite teeth 400 and core guide seat 300 can improve the structural rigidity and service life of the bite structure 200, thereby extending the service life of the bite mold 600, making the bite mold 600 simple in structure and easy to produce and manufacture.

[0052] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
