Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of dashboard foaming molds for automotive parts, specifically a foaming mold pressing device. Background Technology
[0002] Currently, during the instrument panel foaming process, the upper foaming mold is manufactured based on the second surface data of the instrument panel injection molding skeleton. The upper foaming mold uses vacuum adsorption to position the skeleton, ensuring a seamless fit when the instrument panel injection molding skeleton is placed in the upper foaming mold. The lower foaming mold is manufactured based on the first surface data of the slush-molded skin. The lower foaming mold uses vacuum adsorption to position the slush-molded skin, ensuring a seamless fit when the slush-molded skin is placed in the lower foaming mold. At the start of the foaming process, the instrument panel injection molding skeleton is placed in the upper foaming mold, and the slush-molded skin is placed in the lower foaming mold. Then, the molds are closed by the equipment to begin the foaming production process.
[0003] During the mold closing process of the upper and lower foam molds, the safe movement clearance between the upper mold skeleton and the lower mold skin is usually designed to be 3mm. However, since the instrument panel skeleton is an injection molded part, it is subject to deformation, and the deformation often exceeds 3mm. Typically, the upper foam mold uses a mold vacuum system to adhere the injection molded instrument panel skeleton to the upper mold, but when the deformation exceeds 3mm, the vacuum system cannot correct the deformation of the upper mold skeleton, resulting in a deformation still exceeding 3mm. This causes interference between the upper mold skeleton and the lower mold skin during mold closing. During the mold closing process, the skeleton scrapes against the skin, leading to the scrapping of the foamed parts and severely impacting the efficiency of the foam production process. Summary of the Invention
[0004] To address the problem of excessive deformation in the front defrost panel area of the instrument panel injection molding frame leading to the scrapping of foamed parts, this utility model provides a foaming mold clamping device.
[0005] The technical solution of this utility model is as follows:
[0006] A foaming mold pressing device, comprising:
[0007] A foaming upper mold and a pushing mechanism connected to the foaming upper mold, the pushing mechanism being in contact with a first surface in the front defrost panel area of the instrument panel injection frame;
[0008] When the instrument panel injection frame is placed on the foam upper mold, the pushing mechanism pushes the instrument panel injection frame so that the second surface of the instrument panel injection frame in the front defrost panel area fits into the foam upper mold.
[0009] Preferably, the actuating mechanism includes:
[0010] A cylinder, which is mounted on the foaming upper mold;
[0011] A contour block, which is connected to the cylinder, has a surface designed to conform to the shape of a first surface of the front defrost panel area of the instrument panel injection frame, so that the contour block fits into the front defrost panel area of the instrument panel injection frame.
[0012] When the instrument panel injection frame is placed on the foam upper mold, the cylinder drives the contour block to push the front defrost panel area of the instrument panel injection frame, so that the second surface of the front defrost panel area of the instrument panel injection frame fits into the foam upper mold.
[0013] Preferably, the cylinder is mounted on the foaming upper mold via a mounting bracket.
[0014] Preferably, the mounting bracket includes:
[0015] The first connecting frame has one end fixed to the upper foaming mold;
[0016] The second connecting bracket is fixed to the other end of the first connecting bracket, and the second connecting bracket is disposed on the first surface facing the front defrost panel area of the instrument panel injection frame.
[0017] Preferably, the contour block is made of nylon material.
[0018] Preferably, the first connecting frame is fixed to the upper foam mold with screws.
[0019] Preferably, the first connecting frame and the second connecting frame are integrally formed.
[0020] Preferably, the cylinder is a stroke cylinder.
[0021] Preferably, the cylinder is a hydraulic cylinder.
[0022] Preferably, the cylinder is screwed to the second connecting bracket.
[0023] The beneficial effects of this utility model are as follows:
[0024] The added pushing mechanism pushes the front defrost panel area of the instrument panel injection frame toward the foaming upper mold side to be shaped, so that the front defrost panel area of the instrument panel injection frame fits tightly with the foaming upper mold without gaps, ensuring that the safe distance between the foaming upper mold frame and the foaming lower mold skin is greater than 3mm, thereby ensuring that the upper mold instrument panel injection frame and the skin will not scratch each other when the mold is closed, and completely avoiding the scrapping of foamed parts.

[0031] To facilitate understanding by those skilled in the art, the present utility model patent is further described below with reference to the accompanying drawings. While the description is quite detailed, it should not be construed as limiting the scope of the present utility model patent. Obvious variations and substitutions of the following examples are all within the protection scope of this patent.
[0032] Combination Figures 1-6 This application provides a foaming mold pressing device, comprising:
[0033] The upper foaming mold 1 and the pushing mechanism connected to the upper foaming mold 1 are attached to the first surface of the front defrost panel area 21 of the instrument panel injection frame 2;
[0034] When the instrument panel injection frame 2 is placed on the foam upper mold 1, the instrument panel injection frame 2 is pushed by the pushing mechanism so that the second surface of the front defrost panel area 21 of the instrument panel injection frame 2 is in contact with the foam upper mold 1.
[0035] By pushing the front defrost panel area 21 of the instrument panel injection frame 2 towards the foaming upper mold 1, the front defrost panel area 21 of the instrument panel injection frame 2 is shaped so that it fits tightly with the foaming upper mold 1 without gaps. This ensures that the safe distance between the foaming upper mold frame and the foaming lower mold skin is greater than 3mm, thereby ensuring that there is no scratching between the upper mold instrument panel injection frame and the skin when the mold is closed, and avoiding the scrapping of foamed parts.
[0036] In this embodiment, the pushing mechanism includes:
[0037] Cylinder 4 is mounted on the foaming upper mold 1;
[0038] The contour block 3 is connected to the cylinder 4, and the contour block 3 has a surface designed to conform to the shape of the first surface of the front defrost panel area 21 of the instrument panel injection frame 2, so that the contour block 3 fits into the front defrost panel area 21 of the instrument panel injection frame 2.
[0039] When the instrument panel injection frame 2 is placed on the foaming upper mold 1, the cylinder 4 pushes the surface of the contour block 3 to contact the first surface of the front defrost panel area 21 of the instrument panel injection frame 2, so that the second surface of the front defrost panel area 21 of the instrument panel injection frame 2 fits with the foaming upper mold 1.
[0040] Among them, cylinder 4 can be a stroke cylinder or a hydraulic cylinder.
[0041] When using the stroke cylinder, the stroke of the stroke cylinder is set according to the gap between the front defrost panel area 21 of the instrument panel injection frame 2 and the upper foam mold 1. The stroke of the stroke cylinder is set to be slightly larger than the gap between the front defrost panel area 21 of the instrument panel injection frame 2 and the upper foam mold 1, so that the front defrost panel area 21 of the instrument panel injection frame 2 and the upper foam mold 1 fit tightly, but without damaging the structure of the instrument panel injection frame 2.
[0042] Similarly, when using a hydraulic cylinder, the hydraulic pressure of the hydraulic cylinder is set according to the gap between the front defrost panel area 21 of the instrument panel injection frame 2 and the foaming upper mold 1.
[0043] In this embodiment, the contour block 3 is made of nylon material, for example. Nylon material is low in cost and easy to design the surface shape of the contour block according to the first surface shape of the front defrost panel area 21 of the instrument panel injection frame 2.
[0044] In this embodiment, during the operation of the dashboard foaming mold, the cylinder 4 is mounted to the upper foaming mold 1 via the mounting bracket 11. For example, Figure 6 The mounting bracket 11 includes: a first connecting bracket 111, one end of which is fixed to the upper foam mold 1; and a second connecting bracket 112, which is fixed to the other end of the first connecting bracket 111, and the second connecting bracket 112 is disposed on a first surface facing the front defrost panel area 21 of the instrument panel injection frame 2.
[0045] Combination Figure 6 The first connecting bracket 111 and the second mounting bracket 112 are arranged in an inverted L-shape on the front defrost panel area 21 of the instrument panel injection frame 2, such that the cylinder 4 and the contour block 3 are positioned between the second connecting bracket 112 and the first surface of the front defrost panel area 21.
[0046] In this embodiment, the first connecting frame 111 is fixed to the upper foaming mold 1 with screws, and the second connecting frame 112 is connected to the cylinder 4 with screws. The screw connection method facilitates disassembly and maintenance of the structure.
[0047] In this embodiment, the first connector 111 and the second connector 112 are integrally formed, which facilitates product manufacturing.
[0048] When the instrument panel injection frame 2 is placed on the foam upper mold 1, as Figure 4 As shown, due to the deformation of the front defrost panel area 21 of the instrument panel injection frame 2, the second surface of the front defrost panel area 21 of the instrument panel injection frame 2 cannot fit with the upper foam mold 1, and there is a gap of more than 3mm between them. At this time, the stroke cylinder 4 is in a non-working state, and the surface of the contour block 3 contacts the first surface of the front defrost panel area 21 of the instrument panel injection frame 2.
[0049] like Figure 5 When cylinder 4 is in operation, the clamping force of cylinder 4 is transmitted through the contour block 3 to the first surface of the front defrost panel area 21 of the instrument panel injection frame 2, so that the second surface of the front defrost panel area 21 of the instrument panel injection frame 2 is tightly fitted with the foaming upper mold 1. This ensures that during the foaming and molding process, the foaming upper mold 1 and the second surface of the front defrost panel area 21 of the instrument panel injection frame 2 are tightly fitted without gaps, thus guaranteeing the foaming quality.
