Abstract

The utility model provides a split type foaming mold for adapter forming. The split type foaming mold is composed of six split modules including an upper module, a lower module, a left middle block, a right middle block, a rear middle block and a front plugging block. Each module can be independently separated and is fixedly connected with other modules through screws, the precision is guaranteed, before the foam pad is formed through foaming, a rubber pad is installed in a mold and is pressed through the four modules (namely the left middle block, the right middle block, the rear middle block and the front plugging block), then the foam pad is formed through foaming in a cavity, and the foam pad is fixed to the mold. The foam pad and the rubber pad are combined together while the foam pad is formed through foaming.

Description

Technical Field

[0001] The utility model relates to a molding die for a missile adapter, in particular to a split foaming die for adapter molding. Background Art

[0002] Figure 1 A schematic diagram of a common missile adapter is shown, which consists of a foam pad 1 and a rubber pad 2. The rubber pad 2 needs to be firmly fixed to the lower end surface of the foam pad 1. At present, most manufacturers choose to use bonding to fix the rubber pad 2 to the lower end surface of the foam pad 1. Although this method is simple and easy, it is not strong and is prone to falling off or shifting. In addition, there are some environmental issues with glue bonding. During the manufacturing process, the large amount of glue used may release harmful chemicals, posing a threat to the environment and workers' health.

[0003] On this basis, the utility model provides an adapter forming die which can fix the rubber pad and the foam pad together without the aid of bonding. Utility Model Content

[0030] The upper end faces and lower end faces of the left middle block 30, the right middle block 40 and the rear middle block 50 are respectively provided with a first positioning protrusion 31 and a first positioning groove 32, the upper surface of the lower module 20 is provided with a plurality of second positioning protrusions 22 corresponding to the first positioning grooves 32, and the lower surface of the upper module 10 is provided with a plurality of second positioning grooves 11 corresponding to the first positioning protrusions 31.

[0031] A plurality of long bolts 4 pass through the upper module 10, the left middle block 30 (or the right middle block 40) from top to bottom and are threadedly connected to the lower module 20, and a plurality of short bolts 5 pass through the lower module 20 from bottom to top and are threadedly connected to the rear middle block 50 (or the left middle block 30 or the right middle block 40). Figure 3 As shown, the front blocking block 60 is provided with a first long hole 61 and a second long hole 62 on both sides, the first long hole 61 extends to the lower edge of the front blocking block 60, and the first transverse bolt 63 and the second transverse bolt 64 pass through the first long hole 61 and the second long hole 62 respectively to be fixedly connected with the left middle block 30 and the upper module 10. Through the above-mentioned bolt fixing form, after the assembly is completed, the six split modules are well combined together, while ensuring the overall accuracy.

[0032] The upper module 10, the lower module 20, the left middle block 30, the right middle block 40, the rear middle block 50 and the front blocking block 60 assembled together are provided with a foaming cavity 7 for forming the foam pad 1, and any one of the upper module 10, the left middle block 30, the right middle block 40, the front blocking block 60 of the rear middle block 50 is provided with a foaming material injection hole (not shown in the figure). Among them, the upper surface of the lower module 20 is provided with a rubber pad installation groove 21 for placing the rubber pad 2, and the lower surfaces of the left middle block 30, the right middle block 40, the rear middle block 50 and the front blocking block 60 are pressed against the upper surface of the edge of the rubber pad 2 in the rubber pad installation groove 21.

[0033] When processing the adapter using the split-type adapter forming foaming mold, first place the rubber pad 2 in the rubber pad installation groove 21 on the lower module 20, then install the left middle block 30, the right middle block 40, and the rear middle block 50 on the lower module 20, and then install the upper module 10, and use the long bolt 4 to fix the upper module 10, the left middle block 30, the right middle block 40, and the lower module 20 together. Then use the short bolt 5 to fix the lower module 20 with the rear middle block 50, the left middle block 30, and the right middle block 40 together.
