Description

TECHNICAL FIELD

[0001] The application relates to the technical field of mold stripping structures, in particular to a front mold oblique spring stripping mechanism for an automobile auxiliary instrument panel. BACKGROUND

[0002] The automobile auxiliary instrument panel, as an important part of the vehicle interior, not only bears the responsibility of displaying the running state of the vehicle, but also is a key interface for information interaction between the driver and the vehicle.

[0003] At present, the automobile auxiliary instrument panel is usually injection molded by an injection mold. In the injection molding process, after the plastic raw material is injected into the mold cavity, the automobile auxiliary instrument panel is separated from the mold cavity by the ejection mechanism or hydraulic cylinder on the injection molding machine after a period of cooling and solidification. However, the automobile auxiliary instrument panel has a side hole perpendicular to the stripping direction. In order to form the side hole, the mold cavity has a forming side rod matched with the side hole. If the product is directly ejected by the ejection mechanism, the forming side rod is easy to damage the side hole, affecting the product yield. CONTENT OF THE UTILITY MODEL

[0004] In order to reduce the probability of damage to the side hole by the forming side rod when the product is ejected, the application provides a front mold oblique spring stripping mechanism for an automobile auxiliary instrument panel.

[0005] The application provides a front mold oblique spring stripping mechanism for an automobile auxiliary instrument panel, which adopts the following technical scheme:

[0006] The front mold oblique spring stripping mechanism for the automobile auxiliary instrument panel comprises a slanting spring fixed block fixed to an upper mold, a slanting spring sliding block slidingly installed in a mold cavity, a connecting rod connecting the slanting spring fixed block and the slanting spring sliding block, and an elastic element sleeved on the connecting rod, the slanting spring sliding block has a forming side rod for side hole forming, and the slanting spring sliding block is arranged to be inclined to slide, when the lower mold moves away from the upper mold, the elastic element restores the deformation and makes the slanting spring sliding block inclined to slide, and the forming side rod is separated from the side hole.

[0007] By adopting the above technical scheme, before the automobile auxiliary instrument panel is stripped, the lower mold core is moved away from the upper mold, so that the compression state of the elastic element is released, the elastic element restores the deformation to drive the slanting spring sliding block to move obliquely, so that the forming side rod moves horizontally away from the side hole, and the forming side rod and the side hole are staggered. At this time, the product can be pushed out of the mold cavity by the stripping mechanism. Through the arrangement of the oblique spring stripping mechanism, the probability of damage to the product by the forming side rod during stripping is reduced. At the same time, the arrangement of the elastic element enables the slanting spring sliding block to be reset to the initial state during the next injection of the product, facilitating the formation of the side hole of the subsequent product.

[0013] By adopting the above technical scheme, the connecting rod is obliquely inserted into the inclined insertion slot, thereby improving the connection stability of the connecting rod and the oblique elastic sliding block. The fixing of the connecting rod and the oblique elastic sliding block is realized through the cooperation of the locking groove and the end of the connecting rod. The assembly operation is convenient, and the connection is stable.

[0014] Optionally, the connecting rod and the locking groove are threadedly connected.

[0015] By adopting the above technical scheme, the cooperation of the connecting rod and the locking groove is specifically disclosed. The cooperation is realized through threads, which has the effects of convenient assembly and stable structure. Meanwhile, it is convenient for maintenance personnel to disassemble the connecting rod from the mold for maintenance.

[0016] Optionally, the oblique elastic fixing block is provided with an inclined through hole corresponding to the inclined insertion slot, and a limiting ring for limiting the connecting rod from being pulled out is arranged on the inner wall of the inclined sliding groove.

[0020] Optionally, the side wall of the oblique elastic sliding block is provided with an inclined surface for guiding sliding.

[0021] By adopting the technical scheme, the inclined surface is arranged, so that the oblique elastic sliding block can slide more smoothly under the action of the elastic element, and the efficiency of the shaped side rod being detached from the side hole is improved.

DETAILED DESCRIPTION

[0033] The following will be described in detail with reference to the accompanying drawings. Figures 1-4 The application is further described in detail.

[0034] The embodiment of the application discloses an inclined elastic demolding mechanism for a front mold of an automobile auxiliary instrument panel.

[0035] Reference Figure 1 and Figure 2 An inclined elastic demolding mechanism for a front mold of an automobile auxiliary instrument panel, comprising an inclined elastic fixed block 1, an inclined elastic sliding block 2, a connecting rod 3 and an elastic member 4. The inclined elastic demolding mechanism is fixed as a whole on an upper mold core 5 of an upper mold, and the position of the upper mold in the mold is defined as the upper side, and the position of the lower mold is defined as the lower side.

[0036] Reference Figure 2 and Figure 3 The inclined elastic fixed block 1 is in the shape of a rectangular block as a whole, and the upper mold core 5 of the upper mold has a positioning groove 51 on the top for arranging the inclined elastic fixed block 1, and the size of the positioning groove 51 is matched with the inclined elastic fixed block 1. The inclined elastic fixed block 1 is provided with fixed through holes 11 penetrating through the upper and lower side end faces at the four corners, and the fixed through holes 11 are counterbores. The upper mold core 5 is provided with fixed screw holes 52 corresponding to the fixed through holes 11 on the bottom wall of the positioning groove 51. The bolts pass through the fixed through holes 11 and are threadedly matched with the fixed screw holes 52, so that the inclined elastic fixed block 1 and the upper mold core 5 are fixed.

[0037] Reference Figure 2 and Figure 4 The central region of the inclined elastic fixed block 1 is provided with inclined through holes 12 penetrating through the upper and lower side end faces and for the sliding of the connecting rod 3. The inclined elastic sliding block 2 comprises an inclined elastic sliding part 21 corresponding to the inclined through holes 12 and an inclined elastic forming part 22 arranged at the end of the inclined elastic sliding part 21. The inclined elastic sliding part 21 and the inclined elastic forming part 22 are integrally arranged, and the inclined elastic forming part 22 is provided with a forming side rod 221 for forming a side hole.

[0038] The inclined elastic sliding part 21 is in the shape of an inclinedly arranged rectangular rod as a whole, and the end face thereof facing the inclined elastic fixed block 1 is provided with an inclined insertion slot 211. The inclined insertion slot 211 and the inclined through hole 12 correspond to each other, the inclined angles of the two are consistent, and both are inclined from top to bottom to the center axis of the mold cavity.

[0039] The bottom wall of the inclined slot 211 has a locking slot 212 with an inner diameter smaller than that of the inclined slot 211. The end of the connecting rod 3 inserted into the inclined slot 211 has a locking portion 31 fixedly matched with the locking slot 212. In this embodiment, the locking portion 31 and the locking slot 212 are threadedly fixed. In other embodiments, the locking portion 31 and the locking slot 212 can be fixedly matched by insertion.

[0040] The inclined elastic fixing block 1 integrally has a limiting ring 13 on the side of the inclined through hole 12 facing the inclined elastic sliding block 2. The limiting ring 13 has an inner diameter matched with the outer diameter of the connecting rod 3, and the end of the connecting rod 3 close to the inclined elastic fixing block 1 has a limiting portion 32 abutting against the top of the limiting ring 13. The limiting portion 32 has an outer diameter greater than the inner diameter of the limiting ring 13, so that the probability of the connecting rod 3 coming out of the bottom of the inclined through hole 12 is reduced, and the connection stability of the inclined elastic fixing block 1 and the inclined elastic sliding block 2 is ensured.

[0041] The elastic member 4 is a compression spring member, and its two ends abut against the bottom of the limiting ring 13 and the bottom wall of the inclined slot 211, respectively. In the normal state of the elastic member 4, the inclined elastic forming portion 22 is located below the product side hole as a whole. When the mold is closed, the lower mold core 6 extrudes the inclined elastic sliding block 2 upward, so that the forming side rod 221 corresponds to the side hole.

[0042] In order to improve the efficiency of the inclined elastic ejection, the bottom of the inclined elastic sliding block 2 also has an inclined surface 222 abutting against the inner wall of the product. In this embodiment, the upper mold core 5 is provided with two groups of inclined elastic ejection mechanisms, and the two groups of mechanisms are symmetrically arranged along the center axis of the product, so that the inclined elastic sliding blocks 2 of the two groups of mechanisms move toward each other or away from each other when sliding. The inclined elastic forming portions 22 of the two groups of mechanisms have an ejection gap therebetween, so that the forming side rod 221 can be ejected from the side hole after the elastic member 4 is reset.

[0043] The implementation principle of the inclined elastic ejection mechanism of the front mold of the automobile auxiliary instrument panel in the embodiment of the application is as follows: after the plastic raw material is cooled and solidified, the lower mold core 6 is first moved away from the upper mold, at this time, the elastic member 4 restores the deformation, the inclined elastic sliding block 2 is inclined and slides toward the direction of the lower mold core under the action of the elastic member 4, so that the forming side rod 221 is ejected from the side hole of the product, and then the product is ejected from the mold cavity by the ejection mechanism.

[0044] The above are preferred embodiments of the application, and do not limit the protection scope of the application, so that: any equivalent changes made according to the structure, shape, principle of the application should be covered within the protection scope of the application.
