Abstract

The utility model relates to a local heating device for eliminating the door plate deformation. The local heating device mainly comprises an upper mold and a lower mold. Only a region in contact with a pattern region and a groove in the upper mold and the lower mold is heated to the preset temperature, and a region in contact with an edge region is not heated, so the degradation of opposite angle regions is avoided after the high-temperature pressure preservation, and the whole surface flatness and the pattern attractive appearance of a molding pressing door are ensured. The local heating device has the advantages that the structure is simple, the high-temperature pressure preservation one-step forming of the molding pressing door is ensured, the surface flatness and the pattern attractive appearance of the molding pressing door are ensured, in addition, the degradation such as surface degluing, warping, cracks and the like are also effectively avoided, and the use effect is good.

Description

A kind of area heating installation of eliminating the door-plate distortion

Technical field

The utility model relates to a kind of furniture processing unit (plant), particularly a kind of door-plate heater.

Background technology

Along with the continuous progress and the development of society, people require increasingly high to life staying idle at home.To door, people roughly are divided into it " inside door " and " external door " two big types.Inside door mainly is used in some and need not prevents fires or the occasion of waterproof, like bedroom etc.External door needs specially treated, must reach certain specific (special) requirements such as fire prevention, waterproof or antitheft.No matter be inside door or external door, people hope to find a kind of moderate simultaneously door of instructions for use that both satisfied.Therefore, people have proposed a kind of mold pressing door.Chinese patent CN96100386.3 just discloses a kind of " lightweight fire-proof wooden door ", and CN200920047661.4 discloses a kind of mold pressing door.Because various doors, its internal structure is different, so people are to the various process technology scheme of door proposition of different structure.Chinese patent CN98806095.7 has just proposed a kind of method of making the mold pressing door to wooden synthetic material.Suchlike method, the technology controlling and process relative complex has also improved production cost undoubtedly.In addition, the mold pressing door is being added man-hour, generally need need heat and pressurize the mold pressing door usually in pressurize a period of time under the hot environment.But around the mold pressing door, especially at four corner regions situation such as come unstuck in to a certain degree surface, warpage take place through regular meeting, influence the attractive in appearance of mold pressing door.

Summary of the invention

The deficiency that the utility model exists to prior art just provides a kind of area heating installation of eliminating the door-plate distortion.

A kind of area heating installation of eliminating the door-plate distortion, it mainly comprises upper die and lower die, and the upper die and lower die of said heater are provided with heating region and non-heating region, and non-heating region surrounds heating region.

The heating region of described heater covers groove and pattern area at least.

The counterdie set inside of described heater has heater.

The utility model compared with prior art; The described area heating installation of the utility model is simple in structure; Not only guaranteed mold pressing Men Gaowen pressurize one-shot forming; The surfacing and the pattern that have guaranteed the mold pressing door are attractive in appearance, but also have effectively avoided bad changes such as come unstuck in its surface, warpage, be full of cracks, and result of use is good.

The specific embodiment

To combine concrete embodiment that the content of the utility model is described below.

As shown in Figure 1, be the described door panel structure sketch map of the utility model.The described door-plate of the utility model is a three-decker, mainly comprises plaque 1, door core 2 and backboard 3.Plaque 1 is the front material therefor of door, and its surface can be designed to various patterns.Backboard 3 is the used material in the back side of door.Door core 2 is the chief component of door-plate, adopts macromolecular material to process usually.When processing mold pressing door, door core 2 and plaque 1 corresponding one side are coated adhesive respectively, under mould and heat, door core 2 and plaque 1 are bonded together.Under uniform temperature and pressure, after maintenance a period of time, door core 2 closely bonds together with plaque 1.Likewise, also can backboard 3 and door core 2 closely be bonded together the processing of so basic completion mold pressing door.

As shown in Figure 2, be plaque 1 front view of the described door-plate of the utility model.Plaque 1 can be divided into three zones, i.e. pattern area 1a, groove 1b, marginal zone 1c.The overwhelming majority zone of the center of plaque 1 is pattern area 1a, can be designed to the various patterns that are imbued with aesthetic feeling here.Pattern area 1a is generally rectangle, perhaps is divided into several rectangles, but pattern area 1a global shape still is a rectangle.

Usually in the mold pressing door, be provided with groove 1b around the pattern area 1a, pattern area 1a and other zones are made a distinction, main purpose is the pattern among the outstanding pattern area 1a, attracts consumer's eye.Around groove 1b, promptly be marginal zone 1c.Because common mold pressing door all is a rectangle generally, and pattern area 1a generally also is a rectangle, these two rectangles generally all are similar figures, and coordination so just seems on the whole visual effect of mold pressing door.Distinguish so on the edge of among the 1c, the adjacent corners position between two similar rectangles has just constituted a diagonal regions 1d.When adopting the mold pressing form that door-plate is carried out processing mold pressing door, since the existence of pattern area 1a and groove 1b, bad changes such as diagonal regions 1d always can crack to a certain extent, be full of cracks.

In order to solve the bad change problem of diagonal regions 1d, the utility model proposes a kind of area heating installation.As shown in Figure 3, be the described door-plate area heating installation of the utility model structural representation.The described area heating installation of the utility model mainly comprises patrix 4, heater 5 and counterdie 6.Heater 5 is arranged on the inside of counterdie 6, utilizes 5 pairs of counterdies 6 of heater to heat, and heat is conducted to patrix 4.Patrix 4 has specific pattern with the surface design that counterdie 6 contacts with the mold pressing door, is used for the moulding of pattern area 1a.When the mold pressing door was heated the pressurize moulding, the zone (being heating region A) of the counterdie 6 that only will contact with pattern area 1a, groove 1b was heated to predetermined temperature, and the zone of the counterdie 6 that will contact with marginal zone 1c (being non-heating region B) do not heat.In fact, heating region A is the active heating region, but not heating region B is passive heat affected zone.Because common mold pressing door and pattern area 1a be rectangle, and pattern area 1a is in the center of plaque 1, non-heating region B encirclement heating region A.Likewise, receiving counterdie 6 heat conducting influences, patrix 4 also can produce the higher relatively heating region A of temperature, and the relatively low non-heating region B of temperature.Because counterdie 6 all is a local heating with patrix 4, the area heating installation of the utility model proposition can be fast with pattern area 1a, groove 1b moulding like this, and has avoided the bad change of diagonal regions 1d.In fact,, perhaps adopt other heat insulation structurals, equally also can realize the local heat of counterdie 6 and patrix 4, but this does not break away from the essence of the utility model through the position of adjustment heater 5 in counterdie 6 or through adjusting the shape of heater 5.

Because counterdie 6 is generally metal material, it can heat conduction, and the neighboring area of the non-heating region B that just contacts with heating region A also has certain intensification inevitably.In order further to guarantee the rapid shaping of groove 1b, heating region A should cover groove 1b and pattern area 1a at least, and heating region A can be bigger slightly slightly than both.
