[0002] The car dashboard is an assembly of various indicating instruments and ignition switches installed in the cab. It is installed on the instrument panel or as an accessory on the steering column. The dashboard assembly is like a window, reflecting the operating status of the internal machinery of the car at any time. At the same time, it is the control center of some equipment and the object of decoration. It is the most eye-catching component in the cab. The dashboard assembly has both technical and artistic functions and is one of the representatives of the whole vehicle style. The car instrument is composed of various instruments, indicators, especially the driver's warning lights and alarms, which provide the driver with the required car operating parameter information. The production and processing of the car dashboard requires the use of injection molds to ensure the rapid injection molding of the car dashboard, so it is widely used.

[0003] Generally, when the product is inverted, the core pulling directions of the sliders on the side are inconsistent, but the sliders are relatively dense, so a common pressure strip is needed. The conventional practice is to process different guide angles on both sides of the pressure strip. Since the pressure strip is also processed, when such a pressure strip is processed at two angles, it will cause errors in the angle of the pressure strip, which is not convenient for processing and mold matching. Utility Model Content

[0004] In order to make up for the above shortcomings, the present application provides a slider core pulling structure and a car dashboard mold, which aims to improve the problem that when the molding is at two angles during processing, there will be errors in the angle of the molding, which is inconvenient for processing and mold matching.

[0005] On the one hand, an embodiment of the present application provides a slider core pulling structure, including a rear mold.

[0006] A mold groove is provided on the rear mold, and a first wedge-shaped slide groove is provided on one side of the mold groove of the rear mold. A first slider is slidably arranged inside the first wedge-shaped slide groove, and a parallel core-pulling insert is arranged on the side of the first slider close to the mold groove, so that the first slider can change its angle for core pulling during core pulling.

[0007] In a specific embodiment, the rear mold is provided with second wedge-shaped grooves on both sides of the first wedge-shaped groove, and the side walls of the first wedge-shaped groove and the two second wedge-shaped grooves are provided with wedge-shaped platforms, each of the wedge-shaped platforms is equipped with a pressure strip inside, and the two second wedge-shaped grooves are equipped with second sliders inside, and the sides of the two second sliders and the first slider are slidably connected to the bottom of each pressure strip.

[0008] In a specific embodiment, each of the wedge-shaped platforms is tilted downward outward, and each of the pressure strips is horizontally arranged with each of the wedge-shaped platforms.

[0009] In a specific embodiment, first wear-resistant sheets are disposed inside the first wedge-shaped slide groove and the two second wedge-shaped slide grooves, and the three first wear-resistant sheets are in contact with the bottom of the first sliding block and the bottom of the second sliding block respectively.

[0010] In a specific embodiment, a second wear-resistant sheet is connected to the outer sides of the first sliding block and the second sliding block.

[0011] In a specific embodiment, a connecting spring is disposed on the inner side of each of the first sliding block and the second sliding block, and the other end of the connecting spring is connected to the inner side wall of the first wedge-shaped sliding groove and the second wedge-shaped sliding groove.

[0012] In a specific embodiment, bosses are provided on both sides of the first sliding block and the second sliding block, and the bosses on both sides are slidably connected to the bottom of the pressure strip.

[0013] On the other hand, the embodiment of the present application further provides an automobile instrument panel mold, comprising

[0014] The above-mentioned slider core-pulling structure and front mold, the front mold is arranged on the rear mold.

[0015] Beneficial effect: the pressure strip has the same angle, and the first slider and the second slider have the same core pulling angle, but the first slider slides at an angle and the core pulling insert slides in parallel, so that the first slider and the core pulling insert adopt T-slot sliding, which can be suitable for core pulling at multiple angles, and the first slider and the core pulling insert are guided separately, which solves the problem of inconsistent core pulling and is more convenient when assembling the mold, without the need for additional processing of pressure strips.

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0027] See also Figure 1-Figure 8 The present application provides a slider core pulling structure, including a rear mold 2.

[0028] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8A mold groove 21 is provided on the rear mold 2, and a first wedge-shaped slide groove 3 is provided on one side of the mold groove 21 of the rear mold 2. A first slider 9 is slidably provided inside the first wedge-shaped slide groove 3, and a parallel core-pulling insert 13 is provided on the side of the first slider 9 close to the mold groove 21, so that the first slider 9 can change the angle for core pulling during core pulling. The rear mold 2 is provided with second wedge-shaped slots 4 on both sides of the first wedge-shaped slot 3. The side walls of the first wedge-shaped slot 3 and the two second wedge-shaped slots 4 are provided with wedge-shaped platforms 5. Each wedge-shaped platform 5 is equipped with a pressure strip 7 inside. Specifically, there are four pressure strips 7, which are fixed to the four wedge-shaped platforms 5 by bolts. The bottoms of the two pressure strips 7 on both sides are slidably connected to the two sides of the two second sliders 6, and the two sides of the two middle pressure strips 7 are slidably connected to one side of the first slider 9 and the other end of the second slider 6, so that the two middle pressure strips 7 need to press the first slider 9 and the second slider 6 at the same time. In this embodiment, there is no need to change the angles of the two middle pressure strips 7. The two second wedge-shaped slots 4 are equipped with second sliders 6 inside, and the sides of the two second sliders 6 and the first slider 9 are slidably connected to the bottom of each pressure strip 7. Among them, the same angle of the pressure strip 7 is adopted, and the core pulling of the first slider 9 and the second slider 6 is also at the same angle, but the first slider 9 is inclined and the core pulling insert 13 is parallel. In this way, the first slider 9 and the core pulling insert 13 adopt T-slot sliding matching, which can be suitable for core pulling at multiple angles, and the first slider 9 and the core pulling insert 13 are guided separately, which solves the problem of inconsistent core pulling and is more convenient when assembling the mold, without the need to process the pressure strip 7 separately.

[0029] In this embodiment, each wedge-shaped platform 5 is tilted downward outward, and each pressure strip 7 is arranged horizontally with each wedge-shaped platform 5. The pressure strip 7 is tilted downward outward, so that the core pulling directions of the first slider 9 and the second slider 6 are consistent.

[0030] In this embodiment, the first wedge-shaped chute 3 and the two second wedge-shaped chute 4 are both provided with the first wear-resistant sheet 8, and the three first wear-resistant sheets 8 are respectively in contact with the bottom of the first slider 9 and the second slider 6. The bottom of the first slider 9 and the second slider 6 can be protected, the service life of the first slider 9 and the second slider 6 can be improved, and the error between the first slider 9 and the first wedge-shaped chute 3 and the second slider 6 and the second wedge-shaped chute 4 can be filled, and the error in the precision of the mold accessories caused by processing can be compensated.

[0031] In the specific setting, the outer sides of the first slider 9 and the second slider 6 are also connected with a second wear-resistant sheet 12. Among them, the outer sides of the first slider 9 and the second slider 6 can be protected to prevent the anti-slip shovel base 10 from directly contacting the first slider 9 and the second slider 6, thereby improving the service life of the first slider 9 and the second slider 6, and filling the error between the first slider 9, the second slider 6 and the anti-slip shovel base 10, and compensating for the precision error of the mold accessories caused by processing.

[0032] In a specific embodiment, a connecting spring is disposed on the inner side of the first slider 9 and the second slider 6, and the other end of the connecting spring is connected to the inner side wall of the first wedge-shaped slide groove 3 and the second wedge-shaped slide groove 4. The first slider 9 and the second slider 6 are prevented from falling off during core pulling.

[0033] In a specific embodiment, bosses 61 are provided on both sides of the first slider 9 and the second slider 6, and the bosses 61 on both sides are slidably connected to the bottom of the pressure strip 7. Herein, the sliding of the first slider 9 and the second slider 6 is realized.

[0034] See also Figure 1-Figure 8 The present application also provides an automobile instrument panel mold, comprising

[0035] The above-mentioned slider core-pulling structure and front mold 1, the front mold 1 is arranged on the rear mold 2, and three anti-slip shovel bases 10 are installed on the front mold 1. The three anti-slip shovel bases 10 are tightly pressed against the first slider 9 and the second slider 6 respectively when the front mold 1 is closed, so that the first slider 9 and the second slider 6 are more stable during injection molding.

[0036] The working principle of the slider core-pulling structure and the automobile dashboard mold:

[0037] The same angle of the pressure strip 7 is adopted, and the core pulling of the first slider 9 and the second slider 6 is also at the same angle, but the first slider 9 slides at an angle, and the core pulling insert 13 slides in parallel, so that the first slider 9 and the core pulling insert 13 adopt T-slot sliding matching, which can be suitable for core pulling at multiple angles, and the first slider 9 and the core pulling insert 13 are guided separately, which solves the problem of inconsistent core pulling and is more convenient when assembling the mold, without the need to process the pressure strip 7 separately.
