Description

Technical Field

[0001] The utility model belongs to the technical field of molds, and in particular relates to an adjustable automobile seat side trim mold. Background Art

[0002] The automobile seat side trim molding mold includes a lifter. During the product design process, due to the change in the mold undercut amount, the lateral stroke requirements of the lifter are different. Usually, the lifter rod is designed with a fixed angle, and it is difficult to adjust the angle according to the lateral stroke requirements. Therefore, it is necessary to adjust the straight ejection stroke of the lifter, which is usually achieved by replacing the mold stroke limit column. This requires a lot of work and is costly.

[0003] In injection molding, it is usually hoped that the vertical ejector stroke is as small as possible. However, if the vertical ejector stroke of the inclined ejector is smaller, the removal margin will be smaller, which may affect the removal of the molded product and cause the product to be unable to be removed.

[0004] The cost of mold development is expensive. From the perspective of the enterprise, it is hoped that in the early stage of trial production, the ejection stroke of the inclined ejector can be fine-tuned to achieve molding. When pursuing mass production, it is necessary to achieve the ultimate injection molding time and the ultimate mold ejection stroke. A set of molds can be reused, so it is necessary to develop an adjustable molding mold. Utility Model Content

[0005] Based on this, the utility model proposes an adjustable automobile seat side trim mold, which can adjust the ejection stroke of the inclined ejector.

[0006] To achieve the above-mentioned purpose, the technical solution of the utility model is: an adjustable automobile seat side trim panel mold, including a base plate, an ejector plate, a lower mold, an upper mold, an inclined ejector and a stroke limit column, the lower mold is fixed on the base plate, and the upper and lower molds are combined to form a mold cavity; the ejector plate is fixed on the base plate and is located in the mold cavity, the base plate is provided with a cylinder and a middle support edge, the ejector plate can slide along the middle support edge driven by the cylinder, the inclined ejector is provided between the lower mold and the upper mold, and one end passes through the ejector plate and is fixed to the base plate; one end of the stroke limit column is fixed to the base plate, and the other end is slidably connected to the upper mold; and a tooth groove is provided on the stroke limit column, and a limiting tooth block is provided in the tooth groove.

[0007] The device sets a limit tooth block on the stroke limit column. When the ejection stroke needs to be adjusted, the limit tooth block is taken out from the tooth groove and then inserted into the appropriate position in the tooth groove to adjust the limit. When the ejection stroke is the smallest and all the inclined ejectors do not buckle the product, and the robot takes the product smoothly, it is adjusted into place. It is convenient and fast, and there is no need to repeatedly develop molds, which greatly saves development costs and time.

[0008] Preferably, the tooth groove is triangular or trapezoidal, and the corresponding limit block is also triangular or trapezoidal, which is convenient for taking and placing. In addition, the tooth groove adjustment spacing can be adjusted by adjusting the angle of the tooth groove, which is convenient for design.

[0009] Preferably, the tooth groove angle is 15-30°, and more preferably, the tooth groove angle is 20°, and the spacing is 3 mm per adjustment.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] The utility model optimizes the travel limit column structure of the existing automobile seat side trim panel mold, arranges a tooth groove above the travel limit column, and arranges a limit tooth block in the tooth groove. By changing the position of the limit tooth block in the tooth groove, fine adjustment of the inclined ejector straight ejection stroke can be achieved. It is convenient and quick, does not need to repeatedly develop the mold, and greatly saves development cost and time. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to make the purpose, technical solution and advantages of the invention clearer, the utility model is described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] like Figure 1-2 As shown, during the molding of the inclined top mold, if the undercut value A is found to be insufficient after loading, it needs to be changed to value B. At this time, the inclined top stroke needs to be changed. Usually, the B of each inclined top 5' is different, which will cause the inclined top lateral stroke C on the mold to have many different values. Usually, the C value = undercut amount B + 1 to 5 mm of the removal margin. Before the molding trial production, the inclined top 5' has been processed on the mold, and the angle of the inclined top is fixed and solidified. In this way, each C value needs to adjust the D value for a vertical ejection stroke D value.

[0019] The larger the D value is, the longer the ejection time and the injection molding cycle will be. For injection molding, it is hoped that the ejection stroke D is as small as possible. However, the smaller D is, the less the allowance for taking out the parts. If the allowance for taking out the parts is too small, the product may not be taken out. Although there are many factors that affect the allowance for taking out the parts, such as injection pressure, temperature, plastic material, shrinkage rate, etc., these are difficult to quantify. Therefore, at present, the D value is adjusted to meet the needs of different undercut amounts. At present, the actual production is achieved by replacing the mold stroke limit column, which is labor-intensive and costly. To this end, the existing structure is optimized so that the D value of the vertical ejection stroke of the inclined ejector can be fine-tuned to meet the needs of different production conditions.

[0020] Example 1

[0021] like Figure 3-5 As shown, an adjustable automobile seat side trim mold includes a base plate 3, an ejector plate 6, a lower mold 2, an upper mold 1, an inclined ejector 5 and a travel limit column 4. The lower mold 2 is fixed on the base plate 3, and a mold cavity is formed after the upper mold 1 and the lower mold 2 are combined; the ejector plate 6 is fixed on the base plate 3 and is located in the mold cavity. A cylinder 7 and a middle support edge 8 are provided on the base plate 3. The ejector plate 6 can slide along the middle support edge 8 driven by the cylinder 7. The inclined ejector 5 is provided between the lower mold 2 and the upper mold 1, and one end passes through the ejector plate 6 and is fixed to the base plate 3; one end of the travel limit column 4 is fixed to the base plate 3, and the other end is slidably connected to the upper mold 1; and a tooth groove 41 is provided on the travel limit column 4, and a limit tooth block 42 is provided in the tooth groove 41.

[0022] The ejection stroke of the inclined ejector 5 is controlled by the stroke limit column 4. When the ejection stroke of the inclined ejector 5 needs to be adjusted, the limit tooth block 42 is taken out from the tooth groove 41, and then inserted into the appropriate position in the tooth groove 41 to adjust the limit. When the ejection stroke is the smallest, and all the inclined ejectors do not buckle the product, and the robot can take the product smoothly, it is adjusted to the right position. It is convenient and fast, and there is no need to repeatedly develop molds, which greatly saves development costs and time.

[0023] The tooth groove 41 is triangular, and the corresponding stopper is also triangular, which is convenient for taking and placing. In addition, the tooth groove adjustment spacing can be adjusted by adjusting the angle of the tooth groove, which is convenient for design. Preferably, the tooth groove angle range is 15-30°. In this embodiment, the tooth groove 41 angle is 20°, and the spacing is 3mm per adjustment. In addition, the tooth groove 41 can also be trapezoidal, and correspondingly, the stopper can also be processed into a trapezoidal shape.
