Description

Technical Field

[0001] The utility model belongs to the technical field of molds for producing automobile accessories, and in particular relates to an inclined ejector rod assembly in a mold for producing automobile accessories. Background Art

[0002] With the rapid development of the modern automotive industry, competition is becoming increasingly fierce, and new designs and processes are constantly emerging, especially in the automotive interior sector. Trim components (such as the instrument panel) occupy a crucial position at the front of the vehicle's cabin, so the impact of their overall design innovation is even greater. Currently, the instrument panel's upper trim panel utilizes a completely new structure with an extra-long internal concave structure. Traditional long sloping roof structures cannot meet production requirements. A multi-segment, split design is required, with fixed inserts and gate sloping roofs positioned on the same side to achieve satisfactory results in terms of structural demolding, efficiency, and quality.

[0003] Based on the above status quo, the present application further designs and improves the inclined ejector assembly in the mold for producing automotive accessories. Utility Model Content

[0022] See also Figure 1 The utility model relates to a mold for producing automobile accessories, wherein the mold 1 is used to produce automobile accessories 2. Figure 2 In the embodiment, the lower portion of the automobile trim is supported by a plurality of inclined lift rod assemblies.

[0023] Let’s look at it more specifically Figures 2 to 6 The utility model relates to a lift rod assembly in a mold for producing automobile accessories. The upper end of the lift rod 3 is arranged on the fixed insert 6, and the lower end of the lift rod 3 is arranged on the base 4. The lift rod 3 is a hollow rod with a cooling water flow channel 33 passing through it. The lower end of the lift rod 3 is connected to the cooling water supply system through a joint 7, and the upper end of the lift rod 3 is connected to the water channel in the fixed insert 6.

[0024] from Figure 4It can be seen that, further, the base 4 of the present application is provided with a slide groove, in which a slider 41 is provided, and the lower end of the inclined push rod 3 passes through the slider 41 and is fixed on the slider 41; the bottom of the base 4 is provided with a hollow portion 47, and the lower end of the inclined push rod 3 passes through the hollow portion 47 and is connected to the joint 7. The base 4 in this structure is a universal slide structure, which ensures that the inclined push rod 3 can move flexibly within a certain range during operation to avoid jamming. Furthermore, side slide grooves are provided on both sides of the slide groove, and side sliders 46 are provided in the side slide grooves. The slider 41 is rotatably arranged between the two side sliders 46. This structure further ensures the stability of the moving structure. For example, the movement of the side slider 46 in the side slide groove can realize the movement of the slider 41. At the same time, the rotation setting of the slider 41 can realize the rotation of the inclined push rod 3 within a certain angle, avoiding jamming during operation.

[0025] In addition, in the present application, the upper part of the inclined ejector rod 3 is provided with at least two self-lubricating guide sleeves 5. In this structure, the double-set self-lubricating guide sleeve structure can ensure that the movement and ejection of the inclined ejector rod are smooth during operation without the risk of jamming.

[0026] In this application, several groups of lifter assemblies are installed on one side of a mold for automotive trim production. Adjacent fixed inserts 6 are separated by gate lifters 26. This mechanism utilizes a gate structure with multiple gate lifters 26 to meet product production requirements. Specifically, the fixed insert is split into two parts at the gate lifter, each with a boss and a separate core position. A boss is also provided at the top of the gate lifter. During mold assembly, the core side is first polished and then positioned on the cavity side. The joining line is polished, which reduces the parting line break to an invisible level, improving the product's appearance quality.

[0027] In a specific embodiment, the extra-long concave part on the automobile trim adopts a slanted roof structure and is divided into four independent slanted roofs. Figure 2 The three inclined ejectors on the middle right side adopt different ejection angles, so that the inclined ejectors are dislocated from each other during ejection. At the same time, a straight ejector block is set at the bottom. Combined with the reverse ejector structure inside the inclined ejector, the product can be smoothly and completely disengaged from the inclined ejector during ejection, preventing the product from moving with the inclined ejector, and then the robot can smoothly pick up the part.

[0028] As can be seen from the above description, in the present application, the cooling water channel 33 is integrated into the inclined ejector 3, so that the inclined ejector 3 can be cooled by cooling water while performing normal inclined ejection operations, thereby streamlining the original cooling water channel structure and reducing costs.

[0029] As described above, the utility model provides a lift rod assembly in a mold for producing automotive accessories, wherein the lift rods are equipped with double sets of self-lubricating guide sleeves, and cooling water channels are integrated inside the lift rods. The bottom of the lift rods adopts a universal slide structure, which eliminates the risk of jamming during production and ensures smooth and reliable movement.

[0030] The protection scope of the present invention includes but is not limited to the above embodiments. The protection scope of the present invention is based on the claims. Any replacement, deformation, and improvement of the technology that can be easily thought of by technicians in this field fall within the protection scope of the present invention.
