Description

Technical Field

[0001] This utility model relates to the field of foaming molds, specifically to a foaming mold for an armrest box frame. Background Technology

[0002] As an important component of passenger vehicle interiors, the center console of a car serves both storage and passenger comfort requirements. To enhance tactile comfort and shock absorption, high-end models commonly employ polyurethane (PU) foaming technology to coat the surface of the center console frame with an elastic foam layer. This process requires specialized foaming molds, the design of which directly affects product yield, efficiency, and surface quality. However, existing foaming molds use direct upper and lower mold assembly. The complex structure of the center console, including hidden clips and wiring harnesses, results in a complex mold cavity structure, making one-time molding difficult. Furthermore, during the foaming process, polyurethane material can easily seep into the frame's internal cavity, increasing the difficulty of subsequent manual adjustments. Traditional one-piece molds require multi-angle forceful ejection for demolding, which can easily lead to foam tearing or frame deformation. Summary of the Invention

[0003] To address the shortcomings of the existing technology, this utility model provides a foaming mold for armrest box frame, which has a novel mold structure, high positioning accuracy for armrest box frame, simple mold processing, and high molding quality.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

The lower mold is disposed on the lower mold base plate. The lower mold has a raised contour positioning part in the middle. The lower mold left insert is embedded on the left side of the contour positioning part, the lower mold right insert is embedded on the right side of the contour positioning part, and the lower mold end insert is embedded on one end of the contour positioning part. The upper mold is disposed opposite to the lower mold. An armrest box frame is disposed on the contour positioning part. The armrest box frame and the upper mold support have foaming cavities. A horizontally movable left slider is disposed between the lower mold left insert and the lower mold end insert, and a horizontally movable right slider is disposed between the lower mold right insert and the lower mold end insert.

[0006] Furthermore, the lower mold has positioning bosses at its four corners, and the upper mold has positioning cavities corresponding to the positioning bosses.

[0007] Furthermore, the upper mold edge has limiting teeth, and the lower mold left insert, lower mold right insert, left slider, and right slider have toothed grooves corresponding to the limiting teeth.

[0008] Furthermore, a groove is provided between the left insert of the lower mold and the end insert of the lower mold, and the left slider is slidably disposed in the groove. Both the left insert of the lower mold and the end insert of the lower mold are provided with pressure blocks that limit the upper part of the left slider.

[0009] Furthermore, the front end faces of the left and right sliders have a sealing structure corresponding to the pivot hole on the armrest box frame.

[0010] Furthermore, a translation cylinder mounting plate is provided on the lower mold base plate, and a translation cylinder for driving the left slider or the right slider is provided on the translation cylinder mounting plate.

[0011] The advantages of this utility model include: the mold structure is simple and the design is reasonable, the mold processing difficulty is low, the mold and the armrest box frame are closely integrated, which greatly reduces the risk of overflow, and the use of slider to block the frame shaft hole makes mold opening simple and will not cause foam tearing.

[0016] The present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0017] One such Figures 1-4 The armrest box frame foaming mold shown includes a lower mold base plate 1, a lower mold 2, an upper mold 3, a lower mold left insert 4, a lower mold right insert 5, and a lower mold end insert 6. The lower mold 2 is mounted on the lower mold base plate 2. The lower mold 2 has a raised contour positioning part 21 in the middle, the structure of which is the same as the reinforcing rib and snap-fit ​​structure at the bottom of the armrest box frame. The lower mold left insert 4 is embedded on the left side of the contour positioning part 21, the lower mold right insert 5 is embedded on the right side of the contour positioning part 21, and the lower mold end insert 6 is embedded on one end of the contour positioning part 21. The contour positioning part 21, together with the lower mold left insert 4, lower mold right insert 5, and lower mold end insert 6, constitutes the armrest box frame positioning structure and filling cavity structure. The upper mold 3 is positioned opposite the lower mold 2, and the armrest box frame 7 is mounted on the contour positioning part 21. The armrest box frame 7 and the upper mold 3 support have foaming cavities for filling with foam material. The upper mold 3 is also provided with support nails 31 that press the armrest box frame 7.

[0018] A horizontally movable left slider 8 is provided between the left insert 4 and the end insert 6 of the lower mold, and a horizontally movable right slider 9 is provided between the right insert 5 and the end insert 6 of the lower mold. The front end faces of the left slider 8 and the right slider 9 have a sealing structure corresponding to the pivot hole on the armrest box frame 7. After the mold is closed, the left slider 8 and the right slider 9 move forward to seal the pivot hole on the armrest box frame.

[0019] To ensure high mold closing accuracy and reduce the risk of overflow, the lower mold 2 has positioning bosses 22 at its four corners, and the upper mold 3 has positioning cavities 11 corresponding to the positioning bosses 22.
