Application number is CN 201720002883.9's patent, goes up the mould and can reciprocate on the guide rail, needs the guide rail to lead, and when this patent carried out rubber band cloth heat to scald and press in addition, the one stroke of going up the mould on the guide rail can only carry out the boiling hot pressure on one limit of rubber band, and a rubber band need carry out the cubic and scalds the pressure, and efficiency remains to improve.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is that prior art is scalding when pressing the rubber band, and a rubber band need carry out the cubic and scald and press, and efficiency remains to improve, for solving above-mentioned problem, the utility model provides a rubber band forming die.

The purpose of the utility model is realized with the following mode: the utility model provides a rubber band forming die, includes mould and bed die, the bed die sets up the die cavity unanimous with the rubber band shape, goes up the mould setting and the die cavity complex positive module, and the bed die is fixed in the frame bottom, goes up the mould top and sets up the telescoping device, and the frame top is connected to the telescoping device fixing base, sets up reset spring between last mould and the bed die, and die cavity bottom sets up the electrothermal tube.

The telescopic device is a hydraulic cylinder or an air cylinder.

The female mold cavity is U-shaped, and the male mold block is also U-shaped.

The electric heating pipe is a U-shaped heating pipe matched with the U-shaped female die cavity.

And a heating device is arranged in the male module.

Compared with the prior art, this rubber band forming die, including last mould and bed die, the bed die sets up the negative mould chamber unanimous with the rubber band shape, go up the mould setting and the positive module of bed mould chamber complex, the bed die is fixed in the frame bottom, it sets up the telescoping device to go up the mould top, the frame top is connected to the telescoping device fixing base, it sets up reset spring to go up between mould and the bed die, bed die chamber bottom sets up the electrothermal tube, set up with the negative mould chamber unanimous with the rubber band shape, place the rubber band in the bed die chamber, directly once scald and press just can scald and press all limits that the rubber band need scald and press, prior art when scalding and pressing the rubber band has been solved, a rubber band need carry out the cubic and scald and press, efficiency remains the problem that improves.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

According to the attached drawings 1 to 3, the rubber band forming die comprises an upper die 1 and a lower die 2, wherein the lower die 1 is provided with a female die cavity 3 which is consistent with the shape of a rubber band, the upper die 1 is provided with a male die block 4 which is matched with the female die cavity 3, the lower die 2 is fixed at the bottom of a frame 5, the top of the upper die 1 is provided with a telescopic device 6, a fixed seat of the telescopic device 6 is connected with the top of the frame 5, a reset spring 8 is arranged between the upper die 1 and the lower die 2, the bottom of the female die cavity 3 is provided with an electric heating tube 7, the telescopic device 6 is arranged at the top of the upper die 1, the telescopic device 6 is not connected with the upper die 1, the lower die 2 and the reset spring 8 form a whole which is fixed at the bottom of the frame 5, when the telescopic device 6 is not contacted with the upper die 1, the upper die 1 and the lower die 2 are farthest away from each other under the action of the reset spring 8, and when the telescopic device 6 is contacted with the upper die 1, the telescopic device 6 presses the upper mold 1 against the lower mold 2.

The telescopic device 6 is a hydraulic cylinder or an air cylinder.

The female die cavity 3 is U-shaped, the male die block 4 is also U-shaped, and the U-shaped is because the rubber band is U-shaped.
