Description

Technical Field

[0001] The invention belongs to the field of injection molds, and in particular relates to an inner-drawing inclined-top linkage demoulding mechanism of an automobile front grille mold. Background Art

[0002] Plastic products, such as automobile front grilles, are manufactured using injection molds. Currently, automobile front grilles are typically equipped with radars. The radar is typically mounted by providing a mounting hole in the grille, inserting a radar bracket into the hole, and then attaching the radar to the bracket. In conventional technology, the radar bracket and front grille are separately processed and molded, then assembled together. However, with market changes, some customers are requesting that the radar bracket and front grille be integrally molded to save costs. Analyzing the product's appearance and structure, the following two difficulties must be overcome during mold design for the radar bracket to be released from the mold after integral molding: First, the radar bracket itself and the front grille have different release directions, resulting in an inclination, making it impossible to release the radar bracket together. Second, the radar bracket has a latch hole that locks the radar in place, and the release position of the latch hole overlaps with the release position of the radar bracket itself. Conventional internal pull-out mechanisms for the latch hole interfere with the release mechanism of the radar bracket itself, preventing assembly. Therefore, a design of an internal pull-out, tilted ejection mechanism with a linked push-up mechanism is required to facilitate smooth demolding of the radar bracket. Summary of the Invention

[0003] The purpose of the present invention is to overcome the difficulties of the existing technology and provide an inner-pull-out inclined top linkage demoulding mechanism for a car front grille mold. The inner-pull-out inclined top linkage structure is adopted to achieve smooth demoulding of the radar bracket.

[0004] To achieve the above object, the present invention adopts the following technical solutions: The cam is pressed against the top of the cam and is pressed against the top of the cam, and the cam is pressed against the top of the cam, and the cam is pressed against the top of the cam, and the cam is pressed against the top of the cam, and the cam is pressed against the top of the cam.

[0015] The present invention is described in detail below with reference to specific implementation cases. The following implementation cases will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form.

[0016] like Figure 1 — Figure 5 As shown, the present invention relates to an inner-drawing inclined top linkage demoulding mechanism of a front grille mold of an automobile, comprising an inner-drawing inclined top linkage structure 02 arranged in the mold for demoulding a radar bracket 04 of a front grille 03, a clamping hole being formed on the radar bracket 04, the mold comprising a fixed mold part 01 and a movable mold part 05, the inner-drawing inclined top linkage structure 02 being arranged on the movable mold part 05, the inner-drawing inclined top linkage structure 02 comprising a base 1, a tilted top seat 2 being smoothly arranged on the base, an inclined top seat 2 being obliquely and slidingly connected to an angled top block 3, a radar bracket core block 5 being arranged on the top of the angled top block, the radar bracket core block 5 being matched with the radar bracket 04, the tilted top block An air avoidance area 6 is set in the middle of the angle top block, and an inner withdrawal fixed block 7 is set in the air avoidance area. The inner withdrawal fixed block is slidably connected to the inclined push rod 8 through an inner withdrawal mechanism. The inner withdrawal mechanism includes a translation slider 10 slidably set on the inner withdrawal fixed block 7, and a U-shaped shrinking groove 11 is set on the translation slider 10. A U-shaped shrinking protrusion 12 is set at the bottom of the inclined push rod 8. The U-shaped shrinking protrusion 12 is swingably matched with the U-shaped shrinking groove 11. A card hole core block 9 for inner withdrawal of the card hole is set on the upper part of the inclined push rod 8. The card hole core block 9 is matched with the card hole. The inclined push rod 8 is obliquely inserted into the top of the inclination top block 3, and drives the card hole core block 9 to be withdrawn along the outer wall of the radar bracket core block 5.

[0017] The internal pull-out inclined top linkage structure of this scheme, when demoulding, the movable mold part 05 is driven by the mold opening power to separate from the fixed mold part 01, and the front grille 03 and the radar bracket 04 move with the movable mold part 05. After the mold opening is completed, the ejection power drives the inclined top seat 2 to move forward smoothly on the base 1, thereby driving the inclined top block 3 to slide downward, and the inclined top block 3 drives the top radar bracket core block 5 to move downward and escape from the radar bracket 04. At the same time, since an air avoidance area 6 is set in the middle of the inclined top block 3, the internal pull-out fixed block 7 is located in the air avoidance area 6 does not move, but the inclined ejector rod 8 is obliquely inserted into the top of the inclined ejector block 3. When the inclined ejector block 3 slides downward, the inclined ejector rod 8 moves along with it. Through the reverse force, the inclined ejector rod 8 drives the translation slider 10 to move smoothly outward on the inner withdrawal fixed block 7, that is, the smooth lateral space of the translation slider 10 is exchanged for the space for the inclined ejector rod 8 to slide downward, and through the swing cooperation of the U-shaped shrinkage protrusion 12 and the U-shaped shrinkage groove 11, the inclined ejector rod 8 drives the card hole core block 9 to be withdrawn from the card hole, and the demoulding of the radar bracket core block 5 and the card hole core block 9 is completed.

[0018] Furthermore, an oil cylinder 15 is provided on the outer wall of one side of the mold, the cylinder rod of the oil cylinder is connected to the inclined top seat 2, and a wear-resistant plate 16 is provided at the bottom of the inclined top seat 2. The wear-resistant plate 16 is in contact with the base 1. When demoulding, the oil cylinder 15 drives the inclined top seat 2 to slide on the base 1. At the same time, with the wear-resistant plate, the inclined top seat is prevented from being worn, thereby ensuring the sliding accuracy.

[0019] Furthermore, a travel switch 17 is provided on the outer wall on the other side of the mold, and a connecting rod 18 is provided at the front end of the inclined ejector seat 2. The connecting rod extends out of the mold, and a switch contact block 19 is provided at the front end of the connecting rod. The switch contact block 19 cooperates with the travel switch 17. With the switch contact block, the oil cylinder can be automatically operated or reset, thereby driving the inclined ejector seat to slide or reset.

[0020] Furthermore, an oblique sliding I-shaped groove 20 is provided on the oblique top seat 2, and an oblique sliding I-shaped block 21 is provided on the inclined top block 3. The oblique sliding I-shaped block 21 cooperates with the oblique sliding I-shaped groove 20, and the cooperation is reliable and the oblique sliding is smooth.

[0021] Furthermore, two fixing blocks 25 are provided in the mold, and the two fixing blocks 25 are respectively located outside the two side walls of the tilt top block 3. The two ends of the inner fixing block 7 extend out of the avoidance area 6 and are fixed to the fixing blocks 25 by screws, which is convenient and reliable.

[0022] Furthermore, a guide groove 27 is provided on the outer wall of the radar bracket core block 5, and the upper part of the inclined ejector rod 8 cooperates with the guide groove 27. When withdrawing, the inclined ejector rod 8 is withdrawn obliquely inward along the guide groove 27, so that the card hole core block can be smoothly withdrawn.

[0023] Furthermore, a locking slider 28 is provided in the mold, and the locking slider 28 is driven to slide by an inclined guide column 29. A locking rod 30 is connected to the locking slider, and a locking hole 31 is provided on the outer wall of the inclined top block 3. The locking rod 30 cooperates with the locking hole 31. When the mold is closed, the head of the locking rod is inserted into the locking hole, which effectively prevents the inclined top block from expanding due to the injection pressure.

[0024] Furthermore, a fixing pin 32 is provided on the radar bracket core block 5, and a fixing hole 33 is provided in the tilt top block 3. The fixing pin 32 cooperates with the fixing hole 33. During assembly, the radar bracket core block is placed in the tilt top block, and then the fixing pin is inserted into the radar bracket core block through the fixing hole, which is convenient for installation.

[0025] The above specific embodiments are used to illustrate the present invention rather than to limit the present invention. Any modifications and changes made to the present invention within the spirit of the present invention and the protection scope of the claims shall fall within the protection scope of the present invention.
