Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a mold structure of left and right base plates of a car seat back cushion. Background Art

[0002] The left and right substrates of the car seat back cushion are oblique long strips with inner and outer oblique buckles and dense small buckle positions on both sides. The inner oblique buckles need to be produced by hardware, and the space for multiple dense buckles is small. The mold structure is complex and changeable. In the mold processing industry, for oblique long strips with inner and outer oblique buckles and dense small buckle positions on both sides, the inner oblique buckles need to be produced by hardware, and the space for multiple dense buckles is small. Due to the oblique buckle structure in multiple directions on the upper and lower and right sides, the secondary sliders in the inner and outer directions of the rear mold and the oblique sliders in the left and right directions are matched according to the traditional processing method. The mold structure is complex, the processing volume is large, and the space is insufficient, resulting in poor mold strength affecting the production life, and continuous testing is required. It takes at least 60 days to develop and manufacture the mold, which seriously affects the customer's overall finished product R&D and testing time. Utility Model Content

After reaching the position, the injection molding machine starts to inject glue for production; the mold is opened after the injection molding is completed, the first step: open the front mold 1 and the rear mold 2, and synchronously drive the left and right sliders 8 to move out of the buckle position; the second step: the No. 1 oil cylinder 4 pulls the core to drive the ground side inclined slider 3 to separate from the product buckle position in the direction of demolding; the third step: the hot air No. 2 oil cylinder 11 drives the lifting The lowering plate 10 is raised and lowered to push all the dome pins 9 and the rear mold inclined ejector block 7 to drive the assembled parts and the product to separate from the rear mold 2; then the product and all the assembled parts are taken out; the fourth step is to remove the assembled parts on the product from the product according to the demolding direction, so that the product can be produced normally, by making the core pulling of the rear mold inclined slider cooperate with the multiple directions of the inner movable assembled parts, placing hardware in the assembled parts, combining the left and right inclined sliders, and making movable inserts in the dense buckle to complete the demolding of the product oblique buckle and the small buckle position in the space, while ensuring that the product assembly structure is not affected, reducing the cost of the injection molding machine and the injection molding production cycle, and controlling the mold processing cycle in the shortest time to meet customer requirements.

[0027] See also Figure 2 , 3 As shown in , 4, 5, and 6, water transport holes 16 are provided on the outer sides of the front mold 1 and the rear mold 2.

[0028] It should be noted that the water transport hole 16 of the utility model is a cooling channel of the mold, which is used to control the temperature of the mold, ensure the quality of the plastic parts and shorten the cycle time. The channel allows coolant (usually water) to flow through the mold, helping to quickly and evenly reduce the temperature of the mold, thereby accelerating the cooling and solidification process of the plastic.

[0029] See also Figure 2 As shown, the assembling pieces from left to right are the third movable assembling piece 14 , the second movable assembling piece 6 , the fourth movable assembling piece 15 and the first movable assembling piece 5 .

[0030] It should be noted that the functions of the movable assembly piece No. 3 14, movable assembly piece No. 2 6, movable assembly piece No. 4 15 and movable assembly piece No. 1 5 of the utility model are to produce buckles and vent; movable assembly piece No. 1 5 is made by splicing two movable blocks, and corresponding positions of the two movable blocks are provided with slots for placing hardware; the core pulling of the rear mold inclined slider cooperates with the movable assembly pieces in multiple directions on the inner side, and hardware is placed in the assembly pieces, combined with the left and right inclined sliders, and the movable inserts are cooperated in the dense buckles to complete the demoulding of the product's oblique buckles and small buckle positions, which ensures the product assembly requirements and reduces the injection molding cost while controlling the shortest production time of the mold.

[0031] See also Figure 2 , 4 As shown in FIG. 5 , the rear mold 2 is located at one end of the No. 1 movable mosaic piece 5 and is obliquely fixedly connected to a support plate, and the top of the support plate is fixedly connected to the output end of the No. 1 oil cylinder 4 and the inclined sliding block 3 on the ground side.

[0032] It should be noted that the function of the ground side inclined slider 3 of the utility model is to release the buckle position and vent. The buckle position of the product is formed at a fixed angle by an inclined setting. The No. 1 oil cylinder 4 is used to drive the ground side inclined slider 3 to slide along the fixed angle. During injection molding, the ground side inclined slider 3 cooperates with the rear mold 2 to form a preset injection mold cavity. After molding, the No. 1 oil cylinder 4 drives the ground side inclined slider 3 to separate from the product to prevent it from affecting the demolding of the product by the dome needle 9.

[0033] See also Figure 1 As shown, it also includes a top cover 12, the front mold 1 is fixedly connected to the bottom of the top cover 12, and an injection port is installed on the top of the top cover 12.

[0034] It should be noted that the top cover of the utility model is located at the top of the mold structure, the front mold 1 is fixed to the bottom of the top cover, and the injection port located at the top of the top cover is the channel entrance for the injection molding machine to inject molten plastic into the mold. The molten plastic is accurately guided into the cavity of the mold to fill the mold and form the required parts.

[0035] See also Figure 2 , 4As shown in Figures 5, 6 and 7, a base 13 is installed at the bottom of the rear mold 2, and a lifting plate 10 is slidably installed up and down in the middle of the base 13. A plurality of dome pins 9 are fixedly connected to the top of the lifting plate 10. The dome pins 9 extend to the interior of the rear mold 2 for product demoulding. A rear mold inclined ejector block 7 is slidably connected in the embedding hole of the assembled part, and the top of the dome pin 9 is fixedly connected to the rear mold inclined ejector block 7. A No. 2 oil cylinder 11 is fixedly connected to one side of the base 13, and the output end of the No. 2 oil cylinder 11 is fixedly connected to the lifting plate 10.

[0036] It should be noted that, when the product needs to be demoulded, the front mold 1 is separated from the rear mold 2, the inclined slider 3 on the ground side is pulled out by the No. 1 oil cylinder 4, and the lifting plate 10 is driven upward by the No. 2 oil cylinder 11. The lifting plate 10 drives the dome needle 9 to lift the product upward. At the same time, the dome needle 9 pushes out the assembled parts inside the rear mold 2 through the rear mold inclined ejector block 7, so that it is demoulded together with the product.
