Description

Technical Field

[0001] This utility model relates to the technical field of shock-absorbing pads, and in particular to a molding die for a shock-absorbing pad for an airbag. Background Technology

[0002] The airbag shock absorber is made of rigid plastic as an insert, which is formed by extruding rubber material onto the insert. The top of the insert extends horizontally outward to form an upper ring, and the lower end of the insert has a base. The bottom of the base extends horizontally outward to form a support, such as... Figure 5 As shown, most current molding molds have a core template as a whole, with the upper template, core template, and lower template set sequentially from the top. Inserts cannot be placed into the molding groove of the core template and cannot be removed. When placed from the top, the support cannot pass through the middle section of the molding groove. When placed from the bottom, the upper ring cannot pass through the sealing groove at the bottom of the molding groove. The molded shock-absorbing pad cannot be removed from the molding groove.

Detailed Implementation

[0011] The present invention will now be described in detail with reference to the accompanying drawings.

[0012] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0013] See Figures 1 to 6This utility model provides a molding die for an airbag shock absorber, comprising a lower template 1, on which plate grooves 1.1 are equidistantly spaced along the longitudinal direction. Positioning posts 4 are equidistantly spaced along the transverse direction of the plate grooves 1.1. Two core plates 3 are symmetrically arranged and abutted against each other at the plate grooves 1.1, forming a core template. Guide posts 1.3 are symmetrically arranged on one side of the plate grooves 1.1. Guide holes 3.4 corresponding to the guide posts 1.3 are opened on the core plates 3. The core plates abut against each other and against the side wall of the plate grooves. The lower template 1 and the core plate 3 are provided with an upper template 2. The upper template 2 is provided with a material groove 2.1. The bottom of the material groove 2.1 is provided with a feeding hole 2.2. The inner side of the core plate 3 is provided with a forming groove 3.2 that communicates with the feeding hole 2.2. The bottom of the forming groove 3.2 is provided with a semi-circular sealing groove. The front and rear sealing grooves and the insert 7 are fitted together on the outside of the positioning post 4. The adhesive is blocked by the sealing groove, the bottom foot of the insert, and the positioning post, so the adhesive will not go down. The side wall of the sealing groove is provided with an insert groove 3.3 for the bottom foot of the insert 7 to be inserted. Two core boards sandwiching the insert are placed in the slot. The positioning pin passes through the front and rear sealing slots and the center hole of the insert. The bottom of the insert rests against the positioning pin. Then, the upper template (driven by the cylinder of the hydraulic press) is placed on top. The upper template seals the top of the two sealing slots. The rubber material is blocked by the sealing slots, the bottom of the insert, and the positioning pin, so the rubber material will not fall down. The worker puts the heated rubber material into the material tank. The push cylinder of the hydraulic press pulls the mold into the hydraulic press. The hydraulic press squeezes the rubber material. The hydraulic press is existing technology. The rubber material enters the forming tank from the feed hole. The rubber material wraps around the insert and forms a shock-absorbing pad. The push cylinder pushes out the mold. Then, the upper template and the core board (driven by another cylinder) are lifted in sequence. The worker removes the core boards one by one. After separating the two core boards, the formed shock-absorbing pad is removed.

[0014] A lower protrusion 1.2 is provided horizontally on the groove 1.1. Positioning posts 4 are equidistantly arranged on the lower protrusion 1.2 along the horizontal direction. A lower groove 3.1 corresponding to the lower protrusion 1.2 is opened at the bottom of the core plate 3. An upper protrusion is provided horizontally at the bottom of the upper template, and an upper groove corresponding to the upper protrusion is opened at the upper end of the core plate.

[0015] The bottom of the material trough 2.1 is horizontally provided with a connecting groove for connecting the feed holes 2.2. The connecting groove can distribute the adhesive material to each feed hole.

[0016] See Figure 2 , Figure 6 The lower end of the positioning post 4 has positioning grooves on both the front and rear sides for positioning the bottom feet of the insert 7. The positioning grooves allow the bottom feet of the insert to be inserted, preventing the insert from rotating or shifting during the extrusion of the rubber material.

[0017] Fixing blocks 5 are symmetrically installed on the left and right sides of the upper template 2, and studs 6 are screwed to the side walls of the fixing blocks 5. The cylinder of the hydraulic press pushes the forming mold out, and the studs on both sides of the upper template slide into the space between the upper and lower clamping blocks. The other cylinder of the hydraulic press raises and lowers the two clamping blocks, and the two clamping blocks raise and lower the upper template through the studs.

[0018] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
