[0030] It should be clear that the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the embodiments of the present application.

The singular forms of "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0032] See also Figures 1 to 6 The present invention discloses a forming die for a car cup holder, comprising:

[0033] Front and rear molds,

[0034] The rear mold comprises a rear mold core 11 and a rear mold plate, and the rear mold core 11 is arranged on the rear mold plate;

[0035] Two first core pulling assemblies 2 are arranged opposite to each other; the first core pulling assembly 2 includes an inclined guide column 21, a driving rod 22, a first slider 23, a first core pulling piece 24, a second core pulling piece 25 and a third core pulling piece 26, the inclined guide column 21 is obliquely penetrated by the first slider 23, the upper end of the inclined guide column 21 is fixed to the front mold, the first slider 23 is slidably arranged on the rear mold, the second core pulling piece 25 is fixedly connected to the first slider 23, and the bottom of the second core pulling piece 25 has a guide rail structure 251, and the guide rail structure 251 is from top to bottom. The third core-pulling member 26 is arranged to extend obliquely downward in a direction away from the rear mold core 11, and the upper side of the third core-pulling member 26 has a slide groove that cooperates with the guide rail structure 251, and the third core-pulling member 26 is slidably arranged at the bottom of the second core-pulling member 25; the first core-pulling member 24 has a molding part 241 and a sliding part 242, the molding part 241 is used for molding the product, the sliding part 242 is against the rear mold plate, and there is an insertion cavity between the molding part 241 and the sliding part 242, and the second core-pulling member 25 and the third core-pulling member 26 are sequentially inserted into the insertion cavity from top to bottom. The upper surface of the second core-pulling member 25 is a resistance slope 252 inclined from top to bottom toward the rear mold core 11, and the resistance slope 252 abuts against the upper wall of the plug-in cavity. The third core-pulling member 26 abuts against the upper side of the sliding portion 242. The molding portion 241 of the first core-pulling member 24, the second core-pulling member 25, and the side of the third core-pulling member 26 close to the rear mold plate together constitute the first molding portion of the automobile cup holder. The first molding portion is a molding surface A3 including two concave positions and grooves located on the same side; the first sliding The block 23 is laterally provided with a through stepped hole 231, and the driving rod 22 passes through the stepped hole 231 and is threadedly connected to the first core-pulling member 24. The end of the driving rod 22 away from the first core-pulling member 24 has a radially protruding limiting portion 221. When the front mold and the rear mold are in a mold closing state, there is a spacing distance between the limiting portion 221 and the transition surface 232 in the stepped hole 231; during the mold opening process, when the limiting portion 221 touches the transition surface 232, the first slider 23 drives the first core-pulling member 24 to move.

[0036] The present invention discloses a forming mold for an automobile cup holder. Since the core-pulling direction of the groove is different from that of the recessed position and the core-pulling area of ​​the first forming portion is larger, the present invention divides the core-pulling into three parts. The first slider 23 first drives the second core-pulling member 25 located in the middle to perform the core-pulling movement, and then drives the third core-pulling member 26 and the first core-pulling member 24 to perform the core-pulling movement in turn, thereby completing the core-pulling and demoulding action of the first forming portion of the product.

[0037] Specifically, since the second core-pulling piece 25 is fixedly connected to the first slider 23, the second core-pulling piece 25 moves synchronously with the first slider 23, and the second core-pulling piece 25 is first separated from the automobile cup holder, that is, the middle part of the first molded part is separated from the automobile cup holder; in the process of the second core-pulling piece 25 performing the core-pulling movement, the second core-pulling piece 25 drives the third core-pulling piece 26 to perform the core-pulling movement through the guide rail structure 251, so that the third core-pulling piece 26 moves obliquely upward in the outward direction, and then the third core-pulling piece 26 is separated from the groove of the automobile cup holder, that is, the lower part of the first molded part is successfully separated from the automobile cup holder; when the second core-pulling piece 25 continues to perform the core-pulling movement, until the transition surface 232 touches the limiting part 221 of the driving rod 22, the first slider 23 drives the first core-pulling piece 24 to perform the core-pulling movement, and the upper part of the first molded part and other remaining parts are also successfully separated from the automobile cup holder.

[0038] It should be noted that before the transition surface 232 touches the limiting portion 221 of the driving rod 22, the second core-pulling component 25 also exerts a force on the first core-pulling component 24 in the direction of the core-pulling movement. However, at this time, the existence of the resistance slope 252 requires the first core-pulling component 24 to move uphill if it wants to perform the core-pulling movement. Therefore, the resistance slope 252 hinders the initial movement of the first core-pulling component 24.

[0039] In this embodiment, during the separation of the second core-pulling member 25 from the car cup holder, the contact area between the resistance slope 252 and the upper wall of the plug-in cavity becomes smaller and smaller, so the first core-pulling member 24 may move before the transition surface 232 touches the driving rod 22. To solve this problem, the first core-pulling assembly 2 also includes a first spring 27; the first slider 23 and the first core-pulling member 24 together constitute an installation cavity for installing the first spring 27; the first spring 27 is located at the upper position of the first slider 23 and the first core-pulling member 24, and the length direction of the first spring 27 is the same as the moving direction of the first slider 23; the opposite ends of the first spring 27 are against the opposite walls of the installation cavity; when the front mold and the rear mold are in the mold closing state, the first spring 27 is in a compressed state. When the first slider 23 performs the core pulling movement, that is, when the first slider 23 moves in the direction away from the rear mold core 11, the second core pulling piece 25 moves synchronously with the first slider 23, but the second core pulling piece 25 is in contact with the first core pulling piece 24, and the second core pulling piece 25 may drive the first core pulling piece 24 to move. Therefore, a first spring 27 is arranged between the first core pulling piece 24 and the first slider 23. When the first slider 23 performs the core pulling movement, the first spring 27 opens with the movement of the first slider 23 to release elastic potential energy. The force exerted by the spring on the first core pulling piece 24 is opposite to the force exerted by the second core pulling piece 25 on the first core pulling piece 24. The first spring 27 is used to support the first core pulling piece 24, so that when the core pulling starts, the first core pulling piece 24 is kept stationary, and the second core pulling piece 25 and the third core pulling piece 26 are allowed to perform the core pulling action first.

[0040] Furthermore, a wear-resistant plate 12 is arranged between the rear template and the first slider 23, and a concave hole is arranged at the surface where the rear template is connected to the wear-resistant plate 12; a receiving groove is arranged at the bottom of the first slider 23; the first core pulling assembly 2 also includes a shovel base 281, a stopper 282 and a second spring 283: the shovel base 281 is located in the receiving groove and is fixedly connected to the first slider 23, and a limiting groove 2811 is arranged at the bottom of the shovel base 281; a first inclined surface 2812 is arranged on the side of the limiting groove 2811 close to the rear mold core 11, and the first inclined surface 2812 is inclined from top to bottom toward the direction of the rear mold core 11; the second spring 283 and the stopper 282 are arranged in sequence from bottom to top in the concave hole, and the stopper 282 passes through the wear-resistant plate 12 upward ... A second inclined surface 2821 is provided at the top of the block 282 and close to one side of the rear mold core 11, and the second inclined surface 2821 is parallel to the first inclined surface 2812; the width of the limiting groove 2811 is smaller than the width of the block 282; when the front mold and the rear mold are in the mold closing state, the top of the block 282 is located in the limiting groove 2811 and there is a spacing distance between the block 282 and the first inclined surface 2812; the block 282 is against the first slider 23; during the core pulling process, when the first inclined surface 2812 touches the second inclined surface 2821, the block 282 is acted upon by the shovel base 281, the second spring 283 is compressed and deformed, and the block 282 moves downward so that the block 282 does not protrude from the wear-resistant plate 12. The shovel base 281 moves synchronously driven by the first slider 23. When the first slider 23 starts to move for core pulling, the stopper 282 blocks the first core pulling component 24, so that the first core pulling component 24 cannot move with the first slider 23, and the second core pulling component 25 and the third core pulling component 26 perform the core pulling movement first. After the shovel base 281 touches the stopper 282, with the cooperation of the first inclined surface 2812 and the second inclined surface 2821, the shovel base 281 presses down on the stopper 282, so that the stopper 282 does not protrude from the wear-resistant plate 12, and the stopper 282 can no longer block the first core pulling component 24. At this time, the driving rod 22 just contacts the transition surface 232 of the stepped hole 231, and the first core pulling component 24 performs the core pulling movement again driven by the first slider 23.

[0041] A first spring 27 is provided at the upper position of the first core-pulling component 24 to block the movement of the first core-pulling component 24 at the upper position of the first core-pulling component 24, and on this basis, a flexible blocking structure composed of a shovel base 281 and a stop block 282 is used to block the lower position of the first core-pulling component 24, so as to effectively ensure that the first core-pulling component 24 performs a delayed core-pulling movement; and when the first spring 27 is damaged, the shovel base 281 and the stop block 282 can also block the first core-pulling component 24 to keep the first core-pulling component 24 stationary; and when the shovel base 281 and the stop block 282 are damaged, the first spring 27 can also block the first core-pulling component 24 to keep the first core-pulling component 24 stationary.

[0042] In this embodiment, in order to cool the first core-pulling component 24, a water transport circuit is provided in the first core-pulling component 24, and the water inlet and the water outlet of the water transport circuit are located on the side of the first core-pulling component 24 facing the first slider 23; the first core-pulling assembly 2 also includes two water transport pipes 29, and the two water transport pipes 29 are respectively passed through the first slider 23 and connected with the water inlet and the water outlet.

[0043] In this embodiment, see Figures 1 to 3 The forming mold of the automobile cup holder also includes two second core-pulling assemblies 3 arranged opposite to each other, which are used to pull the core of the second molding part of the automobile cup holder; the second core-pulling assembly 3 includes a core-pulling slider 31 and a driving cylinder 32, the core-pulling slider 31 is movably arranged on the rear mold plate, the fixed end of the driving cylinder 32 is fixed on the rear mold plate, and the driving end of the driving cylinder 32 is connected to the core-pulling slider 31 to drive the core-pulling slider 31 to approach or move away from the rear mold core 11. When the core-pulling work is performed, the driving cylinder 32 drives the core-pulling slider 31 away from the rear mold core 11, separates the core-pulling slider 31 from the second molding part, and keeps the core-pulling slider 31 away from the second molding part by a sufficient distance to avoid the second molding part from colliding with the core-pulling slider 31 when the product is ejected.

[0044] Furthermore, the second core pulling assembly 3 also includes a sensing element 33 and two contact sensing devices 34. The sensing element 33 is connected to the driving end of the driving cylinder 32 through an intermediate carrier. The two contact sensing devices 34 are arranged side by side and spaced apart along the moving direction of the core pulling slider 31. When the sensing element 33 contacts one of the contact sensing devices 34, the core pulling slider 31 is closest to the rear mold core 11. When the sensing element 33 contacts the other contact sensing device 34, the core pulling slider 31 is farthest from the rear mold core 11. Two contact sensing devices 34 are used to determine whether the core pulling slider 31 has moved into place. When the core pulling slider 31 does not move into place, the sensing element 33 cannot contact the contact sensing device 34, and the injection molding machine stops operating. This can avoid the situation where the product quality does not meet the standard due to the core pulling slider 31 not moving into place during injection molding production. For example, when the core-pulling slider 31 performs a core-pulling movement that is less than the expected standard stroke, the core-pulling slider 31 is not far enough away from the second molding part. At this time, the sensing member 33 cannot contact the contact sensing device 34, and the injection molding machine stops operating. This can avoid the second molding part and the core-pulling slider 31 from colliding when the product is ejected.

[0045] Furthermore, the intermediate carrier includes a connecting block 35 and a bar 36; the connecting block 35 has a plug-in portion 351 and an extension portion 352 connected to the plug-in portion 351, the plug-in portion 351 is fixedly connected to the driving end of the driving cylinder 32 and plugged into the core-pulling slider 31, the extension portion 352 is connected to the bar 36, the bar 36 is located on one side of the driving cylinder 32 and the length direction of the bar 36 is parallel to the driving direction of the driving cylinder 32, and the sensor 33 is arranged on the bar 36; with the above structure, the position of the sensor 33 can be flexibly adjusted on the bar 36, which is convenient for the staff to debug.

[0046] Furthermore, in order to further facilitate debugging by the staff, the sensing member 33 is two semi-circular spheres, and the two semi-circular spheres move within the range between the two contact sensing devices 34, and the semicircular parts of the semi-circular spheres are in contact with the contact sensing devices 34. In this way, it is only necessary to adjust the positions of the two sensing members 33, and there is no need to adjust the positions of the two contact sensing devices 34 very accurately.

[0047] In this embodiment, the molding die of the automobile cup holder further includes an ejector pin 4 plate and an ejector pin 4; the ejector pin 4 plate is located below the rear mold plate, the ejector pin 4 is inserted through the rear mold plate and the rear mold core 11, and the bottom of the ejector pin 4 is fixed to the ejector pin 4 plate. After the first core pulling assembly 2 and the second core pulling assembly 3 are pulled, the ejector pin 4 is driven to move upward by the ejector pin 4 plate to eject the product, thereby completing the demoulding of the product.

[0048] The present invention is not limited to the above-mentioned embodiments. If various changes or modifications to the present invention do not depart from the spirit and scope of the present invention, and if these changes and modifications fall within the scope of the claims and equivalent technologies of the present invention, the present invention is also intended to include these changes and modifications.
