Abstract

The invention relates to a warm extrusion die of a switch panel. An upper die of the die comprises an upper die seat, a male die base plate, a guide sleeve, a male die, and screws; the shape of a molded part is formed on the contact surface for molding of the male die, and the contact surface for the molding is connected with the male die base plate through the screw; the upper die seat is connected with the male die base plate through the screw; the guide sleeve is in interference fit with the upper die seat; a lower die of the die comprises a female die, an extrusion piece, a female die reinforcement ring, a guide column, a lower die seat, a lower gasket, a push plate, a push rod, a long screw, a female die insert, and a female die insert reinforcement ring; the lower gasket is arranged in a positioning shallow hole of the lower die seat; the push plate is arranged in the lower gasket; the female die insert is in the interference fit with the female die insert reinforcement ring, and the push rod penetrates into the female die insert and the female die insert reinforcement ring and is arranged in a positioning shallow hole in the lower gasket; the female die is arranged on the female die insert after being in the interference fit with the female die reinforcement ring and then is connected with the lower die seat through the long screw; the guide column is in the interference fit with the lower die seat. According to the technical scheme, the warm extrusion die is simple in structure, easy to manufacture and convenient for heating.

Description

A kind of switch panel temperature extension mould

Technical field

The present invention relates to a kind of switch panel temperature extension mould, belong to extrusion die field, is mainly the structural design of mould.

Background technology

It is more extensive that switch panel is used in daily family, the plastic part that most switch panels adopts, the one, prevent conduction, the 2nd, utilize injection moulding efficiency high, easily moulding, but plastic product is easily aging poor with survivability that bear, at residential building and the villa of many top grades, demand ornament materials requires more and more to have good taste, and not only attractive in appearance but also the life-span is long, wherein switch panel is exactly one of them.Switch panel is the deadweight of material itself with Steel material one, the 2nd, be difficult to moulding, adopt magnesium alloy can guarantee in deadweight, but in the strength of materials too late aluminum alloy materials.Aluminium alloy material makees panel, as long as just can prevent conduction at the surface spraying insulating materials of material.Adopt aluminium alloy 2A12 as switch panel material, extrusion modling temperature range is 400～450 degrees Celsius, belongs to Warm Extrusion.

Summary of the invention

In order to solve the moulding of aluminium alloy switch panel Warm Extrusion, need designing mould, the invention provides one simple in structure, the mould of moulding on hydraulic press.This mould structure has reference value to the part of the similar switch panel class of moulding.

Technical scheme of the present invention is: described temperature extension mould comprises upper and lower mould two parts, patrix is made up of upper bolster, convex mould pad, guide pin bushing, punch, screw etc., punch is processed with the shape of forming part for the contact-making surface of moulding, the other end and convex mould pad screw attachment, punch middle and lower part is processed with a deep hole and uses for placing thermocouple temperature measurement, upper bolster and convex mould pad screw attachment, guide pin bushing and upper bolster interference fit, counterdie is by die, extrusion, die stiffening ring, guide pillar, die shoe, lower gasket, push pedal, push rod, long spiro nail, die plate insert, the formations such as die plate insert stiffening ring, lower gasket is placed in die shoe location shallow bore hole, push pedal is placed in lower gasket, after die plate insert and die plate insert stiffening ring interference fit are good, push rod is located to shallow bore hole through interior being placed in again on lower gasket, die is placed on die plate insert and connects with die shoe with long spiro nail with die stiffening ring interference fit, die plate insert and die plate insert stiffening ring are processed with the hole of a placement temperature thermocouple around, guide pillar and die shoe interference fit.

When use, respectively upper die and lower die are fixed on to upper Mobile base and the lower fixed seat of hydraulic press with T shape piece and screw, place heater outward at die stiffening ring, after upper and lower mould matched moulds, heat, the temperature that mould reaches prescribed limit is plastic use, the blank heating is placed to extrusion modling in die cavity, and after moulding, patrix moves upward, and the lower push rod of hydraulic press drives push pedal and push rod that extrusion is ejected from die.Extrusion can become switch panel product by follow-up stamping procedure again.

Switch panel Warm Extrusion forming die structure described in the present invention is simple, is easy to manufacture, and heating is convenient, and similar or similar forming parts Design of Dies is had to some reference value.

Accompanying drawing explanation

Figure is switch panel temperature extension mould structural representation of the present invention.

1. upper bolsters in figure, 2. convex mould pad, 3. guide pin bushing, 4. punch, 5. die, 6. extrusion, 7. die stiffening ring, 8. die plate insert stiffening ring, 9. guide pillar, 10. die shoe, 11. lower gaskets, 12. push pedals, 13. push rods, 14. long spiro nails, 15. die plate inserts.

The specific embodiment

Described switch panel temperature extension mould is by upper and lower mould two parts, patrix is made up of upper bolster 1, convex mould pad 2, guide pin bushing 3, punch 4, and counterdie is made up of die 5, extrusion 6, die stiffening ring 7, guide pillar 9, die shoe 10, lower gasket 11, push pedal 12, push rod 13, long spiro nail 14, die plate insert 15, die plate insert stiffening ring 8.

Described switch panel temperature extension mould part of the upper die, punch 4 is processed with the shape of forming part for the contact-making surface of moulding, the other end and convex mould pad 2 use screw attachment, punch 4 middle and lower parts are processed with a deep hole and use for placing thermocouple temperature measurement, upper bolster 1 and convex mould pad 2 use screw attachment, guide pin bushing 3 and upper bolster 1 interference fit.

Described switch panel temperature extension mould part of the lower die, lower gasket 11 is placed in die shoe 10 and locates shallow bore hole, push pedal 12 is placed in lower gasket 11, after die plate insert 15 is good with die plate insert stiffening ring 8 interference fit, push rod 13 is located to shallow bore hole through interior being placed in again on lower gasket 11, die 5 is placed on die plate insert 8 and connects with die shoe 10 with long spiro nail 14 with die stiffening ring 7 interference fit, die plate insert 15 and the hole that is processed with a placement temperature thermocouple around die plate insert stiffening ring 8, guide pillar 9 and die shoe 10 interference fit.

When described switch panel temperature extension mould upper and lower mould matched moulds, patrix moves downward, guide pin bushing 3 first coordinates with guide pillar 9, punch 4, die 5, die plate insert 15 are heated to the forming temperature of prescribed limit, the blank heating is placed in to extrusion modling in die cavity, after moulding, patrix moves upward, and the push rod of hydraulic press drives push pedal 12 and push rod 13 that extrusion 6 is ejected from die 5.
