Abstract
The utility model relates to a dual-material composite vacuum forming mould with a gas leading-in device, comprising a dual-material composite vacuum forming mould and a gas leading-in device. The dual-material composite vacuum forming mould is characterized in that: the gas leading-in device comprises a pricking needle and a dual-end hollow cylinder; the pricking needle is arranged in a fixing sleeve which is fixed at the upper end part of a connecting rod in a threaded manner; and the dual-end hollow cylinder is fixed on a lower mould of the dual-material composite vacuum forming mould by a screw. As the gas leading-in device is additionally arranged on the dual-material composite vacuum forming mould, the utility model not only can puncture a layer of plate by the pricking needle, but also can lead external gas into two layers of plates by the dual-end hollow cylinder, so as to maintain the balance of internal and external pressure, thereby optimizing the plate forming process. In addition, time is saved, and the efficiency is high. The dual-material composite vacuum forming mould adopts reasonable design and simple structure, and is convenient to use.
Description
Technical field
The utility model relates to a kind of vacuum forming mould, exactly is a kind of extra quality composite evacuated mould that has the gas gatherer.
Technical background
Extra quality composite evacuated mould is widely used in manufacturing fields such as automobile, agricultural machinery, engineering truck and medicine equipment, is the requisite fundamental technology equipments of manufacturings such as automobile, agricultural machinery, engineering truck and medicine equipment.At present, the main dependence on import of domestic extra quality composite evacuated mould, price height not only, delivery cycle is long, the maintenance cost height, and can't keep when vacuumizing the pressure balance inside and outside the double-deck plate time-consuming because of upper and lower mould, efficient is low.
The utility model content
The utility model purpose is at above-mentioned defective, provide a kind of to people and puncture one deck plate by pricker, utilize hollow double end cylinder that ambient atmos is imported between the double-deck plate again, keep internal and external pressure balance, thereby save time the extra quality composite evacuated mould that has the gas gatherer that efficient is high.
The utility model is made up of extra quality composite evacuated mould and gas gatherer, it is characterized in that: the gas gatherer comprises air cylinder in pricker and the both-end, pricker places in the fixed cover, the fixed cover screw thread is fixed in the connecting rod upper end, and air cylinder is fixed on the counterdie of extra quality composite evacuated mould by screw in the both-end.
Air cylinder comprises cylinder body, piston rod, joint, tracheae in the described both-end, the cylinder body of air cylinder is fixed on the counterdie by screw in the both-end, the piston rod upper end of passing cylinder body is fixed on the connecting rod lower end, piston-rod lower end is equipped with a gas source connector, be connected with tracheae on the joint, the inlet, outlet joint of air cylinder is connected with a tracheae respectively in the both-end.
The gap of pricker and fixed cover is 0.05-0.1mm, and the alloy tool steel Cr12MoV that pricker adopts the back Rockwell hardness that quenches to be in HRC50～55 scopes is a material.
Effect of the present utility model
1, the utility model is owing to installed the gas gatherer additional on extra quality composite evacuated mould, therefore not only can puncture one deck plate by pricker, utilize hollow double end cylinder that ambient atmos is imported between the double-deck plate again, keep internal and external pressure balance, thereby optimize plate forming technology, and save time the efficient height.
2, the utility model is reasonable in design, and is simple in structure, easy to use.

The specific embodiment
Embodiment 1:
Referring to Fig. 1～2, the utility model is made up of extra quality composite evacuated mould and gas gatherer, it is characterized in that: the gas gatherer comprises air cylinder 2 in pricker 1 and the both-end, pricker places in the fixed cover 3, the fixed cover screw thread is fixed in connecting rod 4 upper ends, and air cylinder is fixed on the counterdie 5 of extra quality composite evacuated mould by screw in the both-end.Air cylinder comprises cylinder body, piston rod, joint, tracheae in the described both-end, the cylinder body 6 of air cylinder is fixed on the counterdie by screw in the both-end, piston rod 7 upper ends of passing cylinder body are fixed on the connecting rod lower end, piston-rod lower end is equipped with a gas source connector 8-1, be connected with tracheae 9-1 on the joint, inlet, outlet joint 8-2, the 8-3 of air cylinder is connected with a tracheae 9-2,9-3 respectively in the both-end.The gap of pricker and fixed cover is 0.05-0.1mm, and the alloy tool steel Cr12MoV that pricker adopts the back Rockwell hardness that quenches to be in HRC50～55 scopes is a material.
During use, former heats plate, after heating finishes, upper and lower mould closure, the vacuum system of equipment vacuumizes mould, and form negative pressure between the two-layer plate this moment, and the equipment source of the gas is given air cylinder gas transmission in the both-end, piston rod moves upward, penetrate down tablet by needle body, the source of the gas gas transmission at piston rod rear portion imports air, make keep-up pressure inside and outside the two-layer plate balance, mould plastics sucking moulding and hot pressing up and down; The cold wind cooling; The product after the moulding is manually taken out in die sinking, and a circulation finishes to enter next circulation.
