Problems solved by technology

In the current industry, due to the limitation of domestic production technology, ink printing transfer rubber pedal mats have surface printing that is easy to deform and alias, transfer printing is not clear, high scrap rate, and the production process often cannot meet the high requirements of the automotive industry for appearance. Therefore, domestic printed transfer rubber pedal mats have been imported through imports in the processing link, and the cost is relatively high, and the production efficiency of foreign printed transfer rubber pedal mats is not very high.

Embodiment 1

[0041] combine figure 1 , figure 2 , the vulcanization molding die of a kind of ink printing transfer printing rubber pedal mat of the present embodiment, comprises upper mold 1, middle mold 2, lower mold 3 and floating mandrel 4, wherein the lower surface of middle mold 2 and the upper surface of lower mold 3 The surfaces are respectively provided with mold cavities, and after the mold is closed, the above mold cavities together form the rubber cavity for the printing ink printing transfer rubber pedal pad to be formed, and the middle mold 2 and the upper mold 1 are respectively processed with upper and lower floating core molds 4 The opening of the movement, the top of the opening of the upper mold 1 is located above the floating mandrel 4 and is provided with a limiting disc 5 . Such as figure 2 As shown, the top surface of the lower mold 3 is provided with well-shaped glue running grooves 6 distributed around the cavity of the lower mold 3 , and the glue running groove...

Embodiment 2

[0044] The vulcanization molding die for ink printing transfer rubber pedal pads of this embodiment is basically the same in structure as embodiment 1, the main difference is that the mold of this embodiment can be provided with at least one row of ink printing transfer rubber pedal pads as required Rubber cavities are used for forming, and the rubber running grooves 6 corresponding to the cavities of each row of lower dies 3 are connected to each other. In this embodiment, two rows of rubber cavities are provided, combined with figure 2 , the rubber running grooves around the cavity of each row of lower dies are connected to each other to form a well-shaped rubber running groove. In the present embodiment, the width and height of the rubber running groove 6 are 2.5 mm, and the floating core 4 and the middle mold 2 are clearance fit, and the gap is 0.08 mm, and the floating height of the floating core 4 is 30 mm.

[0045] Adopt above-mentioned vulcanization molding die, the m...

Embodiment 3

[0056] The vulcanization molding die of a kind of ink printing transfer printing rubber pedal pad of this embodiment, its structure is basically the same as embodiment 2, and its difference mainly lies in: the width and the height of rubber running groove 6 in this embodiment are 3mm, floating core Between 4 and the middle mold 2 is clearance fit, and its clearance is 0.12mm, and the floating height of the floating mold core 4 is 40mm.

[0057] A kind of manufacturing method of ink printing transfer printing rubber pedal mat of this embodiment, its basic preparation steps are the same as embodiment 2, the difference is that: material blank is made up of following components according to weight parts: styrene-butadiene rubber: 50 parts, Natural rubber: 50 parts, high wear-resistant carbon black: 65 parts, semi-reinforcing carbon black: 20 parts, zinc oxide: 4.5 parts, stearic acid: 1.2 parts, calcined clay: 16 parts, solid Malone: ​​0.9 parts, Paraffin wax: 0.5 parts, anti-agin...

Abstract

The invention belongs to the technical field of ink transferred rubber products and discloses an ink printing transferred rubber pedal pad vulcanization forming mould and a manufacturing method. The ink printing transferred rubber pedal pad vulcanization forming mould comprises an upper mould, a middle mould, a lower mould and a floating core mould, the lower surface of the middle mould and the upper surface of the lower mould are provided with mould cavities which jointly form a rubber cavity for to-be-formed ink printing transferred rubber pedal pads after mould closing, and the middle mouldand the upper mould are internally provided with holes allowing vertical movement of the floating core mould. By adoption of the technical scheme, ink printings can be clearly transferred to special-shaped rubber surfaces while deformation and deflection of printed patterns are avoided, and high rate of finished products is realized.

Description

technical field [0001] The invention belongs to the technical field of rubber product manufacturing, and more specifically relates to a vulcanization molding mold and a manufacturing method of ink printing transfer rubber pedal pads. Background technique [0002] Car pedals generally consist of three pedals: brake, clutch, and accelerator. In order to increase the comfort of pedaling, the end faces of the pedals are generally square or rectangular iron plates. The larger the area, the more comfortable it is. When stepping on the shoes, the edges and sides are easy to cut and scratch the shoes, and the end surface is more and more slippery. A rubber foot pad is put on, which is non-slip and wear-resistant, and will not hurt the shoes made of any material, and it is more comfortable to step on. [0003] Among them, the brake is an important part used for automobile braking. The performance of the rubber pedal pad for the brake directly affects the safety of the car. Therefore...
