Embodiment 1

[0039] Please refer to Figure 1 to Figure 4 , this embodiment provides a blister mold 100, including:

[0040] The upper mold body 10, the upper mold body 10 has an air extraction hole 11, an upper half cavity 12, an oil injection channel 13, an upper half wedge-shaped mouth 14, an upper arc surface 15 and an upper half plane 16, and the upper half cavity 12 is located on the upper mold body In the middle of 10, the suction hole 11 communicates with the upper half cavity 12 and is used for plastic suction, the upper half wedge-shaped mouth 14, the upper arc surface 15 and the upper half plane 16 are from the outside of the upper mold body 10 towards the upper half cavity 12 directions are distributed sequentially, and the oil injection channel 13 extends from the upper mold body 10 to the position of the upper half plane 16;

[0041] Lower mold body 30, lower mold body 30 has lower half mold cavity 31, lower half wedge-shaped mouth 32, lower arc surface 33 and lower half pla...

Embodiment 2

[0058] This embodiment also provides a plastic-absorbing mold 100. The difference between this embodiment and Embodiment 1 is:

[0059] The surface of the upper half wedge mouth 14 is an inclined plane, and the surface of the lower half wedge mouth 32 is an inclined plane, and the shape of the demoulding wedge 55 fits the shape of the demoulding wedge 101.

[0060] Other structures can refer to embodiment 1.

[0061] By changing the shape of the lower half wedge-shaped opening 32, the speed of demolding can be relatively faster, because the gap that the demolding wedge 55 squeezes out when inserting the demolding wedge 101 will be larger. For some products with better stability, It can increase the demoulding speed to a certain extent without affecting the integrity of the product.

[0062] Also very useful.

Embodiment 3

[0064] This embodiment also provides a plastic-absorbing mold 100. The difference between this embodiment and Embodiment 1 is:

[0065] The oil injection channel 13 on one side has one inlet and multiple outlets, and the multiple outlets are distributed along the length direction of the upper half-plane 16 .

[0066] Other structures can refer to embodiment 1.

[0067] Different inlet and outlet settings can make the cooling oil distribute along the upper half-plane 16, so that the cooling oil can play its role and prevent the product from being too much impact at the moment of demolding.

Abstract

The invention provides a plastic suction mold, and relates to the technical field of plastic suction. The plastic suction mold comprises an upper mold body, a lower mold body, and a mold release moving part. The upper mold body is provided with an air suction hole, an upper half mold cavity, oil injection channels, upper half wedge-shaped openings, upper arc surfaces and upper half planes. The lower mold body is provided with a lower half mold cavity, lower half wedge-shaped openings, lower arc surfaces and lower half planes corresponding to the upper mold body. The side, away from the lower half mold cavity, of the lower mold body further comprises a lower mold base, and the lower mold base is provided with a guide sliding groove. The mold release moving part comprises guide vertical rods, guide cross rods, a mold release pull rod, mold release nuts and mold release wedge-shaped block, the four guide vertical rods are oppositely arranged in the guide sliding groove in pairs, the guidecross rods connect the two guide vertical rods on the same side, the mold release pull rod penetrates through the two guide cross rods, the two mold release nuts sleeve the mold release pull rod andare in threaded fit with the mold release pull rod, and mold release wedge blocks are arranged on the guide vertical rods. The plastic suction mold can guarantee force application balance, prevents aproduct from being impacted by injected gas, and prevents the product from being damaged when the product is de-molded.

Description

technical field [0001] The invention relates to the technical field of plastic absorption, in particular to a plastic suction mold. Background technique [0002] Blister process, a plastic processing process, the main principle is to heat and soften the flat hard plastic sheet, then absorb it on the surface of the mold by vacuum, and form it after cooling. It is widely used in plastic packaging, lighting, advertising, decoration and other industries. In the process of blistering, the sheet is softened by heat, and it is vacuumed to adhere to the surface of the core and molded in the cavity. [0003] Existing plastic molds have some disadvantages in use: [0004] It is easier to cause damage to the formed product during demoulding. Contents of the invention [0005] The purpose of the present invention is to provide a plastic suction mold, which can facilitate demoulding and avoid product damage during demoulding. [0006] Embodiments of the present invention are achieve...
