Embodiment 1

[0017] refer to figure 1 , figure 2 , image 3 and Figure 4 , a six-cavity dust jacket mould, comprising an upper template 1, a middle mold 2, a lower template 3 and a bottom plate 4 for fixing the lower template 3 from top to bottom; the upper template 1 is provided with an upper die groove 11, The lower template 3 is provided with a lower mold groove 31, and the middle mold 2 is composed of a beam 21 and six mold cores 22 installed on the beam 21; when the upper template 1, the middle mold 2 and the lower template 3 are installed together, Between the mold core 22, the upper mold groove 11 and the lower mold groove 31, a mold cavity matching the dust jacket is formed; each side of the front and back of the beam 21 is provided with three mold cores 22 with equal spacing, and the three mold cores 22 on the front side Three mold cores 22 are symmetrical about the beam 21 and the three mold cores 22 on the rear side; the upper surface of the middle mold 2 is provided with a...

Embodiment 2

[0020] refer to Figure 5 , the difference from Embodiment 1 is that: each arc-shaped bend 52 is connected with the corresponding lower die cavity 31 with two verticals 53, and each vertical 53 is connected with the arc-shaped bend 52 All are connected with connecting channels 54 located on the upper surface of the crossbeam 21 , the lengths of all connecting channels 54 are equal, and the two vertical channels 53 are respectively located on both sides of the corresponding lower die cavity 31 .

[0021] The medium-flow rubber path of the present invention is composed of a straight path and six arc-shaped bends with the same length; the rubber material enters the straight path first, and the rubber material flows together to reduce the heat and pressure loss of the rubber material, and then the straight path is evenly distributed to the six paths Curved curves, because the curves are curved, the rubber material flows smoothly, and the length of the six curved curves is the same...

Abstract

The invention provides a dustproof jacket mould with six mould cavities, and aims to solve the problem of non-uniformity of the speed of sizing materials, flowing into mould cavities, of an existing dustproof jacket mould with the six mould cavities. The dustproof jacket mould comprises an upper mould plate, a middle mould and a lower mould plate, wherein upper mould grooves are formed in the upper mould plate; lower mould grooves are formed in the lower mould plate; the middle mould consists of a cross beam and six mould cores; three mould cores are uniformly arranged on each of the front side and the back side of the cross beam; a size flowing channel is arranged on the upper surface of the middle mould and comprises a straightway; the left end and the right end of the straightway are respectively connected with three arc curves; the six arc curves correspond to the six lower mould grooves; a vertical way is arranged between each arc curve and the corresponding lower mould groove. According to the dustproof jacket mould, the sizing materials enter the straightway at first and are gathered together to flow so as to reduce the heat and pressure loss of the sizing materials; the sizing materials are uniformly deployed to the six arc curves through the straightway, so that the sizing materials smoothly flow; because of the same length of the six arc curves, the identical flowing velocity of the sizing materials flowing into the six mould cavities can be guaranteed; the quality of products is consistent so that the reject ratio is reduced.

Description

technical field [0001] The invention relates to a dustproof jacket mold, in particular to a six-cavity dustproof jacket mold. Background technique [0002] As the demand for dust jackets increases, the production efficiency of dust jackets is improved. The existing molds for dust jackets are equipped with multiple cavities. With the increase in the number of cavities, the existing molds for dust jackets are easy There is the problem of uneven flow rate of the rubber into the mold cavity, lack of glue and uneven quality. In addition, when the number of mold cavities increases, the pressure and heat loss of the runners are serious, which is likely to cause a series of defects. Contents of the invention [0003] The invention provides a six-cavity dust jacket mold, which aims to solve the problem of uneven flow of rubber material into each mold cavity in the existing six-cavity dust jacket mold. [0004] In order to solve the above technical problems, the present invention i...
