Abstract

The utility model discloses to a large size plastic thermal forming machine. An upper heating board can be moved on a mould, or retreated on a lower heating board; the lower part of the lower heating board is provided with a moveable air cylinder; the upper part of a moveable clamp board frame is provided with a clamp board which controls the sizes of the working size via a clamping air cylinder. The utility model can raise a mould frame which is provided with an adjustable positioning device, so a plastic product with the working size which can reach 2x3 meters and adjustable thickness is obtained.

Description

Thermoforming machine for plastics

The utility model belongs to the plastic hot processing equipment.

At present, thermoforming machine for plastics generally be that processing dimension is fixed, but the thickness of machining sheet is subjected to certain limitation, to processing the product of various different sizes, or the product of different-thickness, need to use different thermoforming machine for plastics, be unfavorable for developing series of products.

The utility model purpose provides a kind of large-scale thermoforming machine for plastics, and processing dimension can be adjusted, and sheet metal thickness is unrestricted, can process series of products.

The utility model is achieved in that thermoforming machine for plastics, heating plate is two-layer about dividing, upward heating plate moves along track by chain traction, following heating plate promotes to move up and down by mobile cylinder, removable clamping plate frame is by chain traction mobile heating mould between heating plate up and down, variable-sized clamping plate frame is on support frame, but setting is made up of moving forward and backward of framework four limits.Clamping plate is positioned at the clamp frame bottom.

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 thermoforming machine for plastics structural representation;

The removable clamping plate mount structure of Fig. 2 schematic diagram;

Structure of the present utility model is that the plastic plate 13 of desire processing is interposed on the clamping plate frame 8, mould is positioned on and can promotes on the mould frame, heating plate divides two-layer up and down, heating plate is divided into the sub-district of some variable temperatures, wherein going up heating plate 1 can move forward and backward, following heating plate 2 can move up and down, and 4 tractions are moved along track 5 by chain.

Last heating plate can move to mold frame top, but heating mould on the one hand can reach on the one hand at vacuum suction and continue the purpose that heats simultaneously, guarantee do not descended by the temperature of heating of plastic sheet material.

Following heating plate can move up and down, and the bottom has mobile cylinder 3 not only to prevent that plastic plate from heating that to touch heating plate when sagging on fire but also prevent that sagging plate middle part is overheated.

Movably clamping plate frame 10 has two characteristics, one clamping plate frame size can have been formed adjustable positioning device 11 and changed by moving forward and backward of framework four limits, thereby can process the various sizes product, its second splint anchor clamps clamp with clamping cylinder 7, and clamping plate is positioned at clamp frame 6 bottoms, can guarantee like this when mould rises, can not push the plastics clamping plate open, and cause gas leakage.So just make this machinery can process thicker sheet material.For convenience sheet material clamps from the bottom, and sheet material is served the clamp frame bottom by mould, and can promote the mould frame on when moving, adopt adjustable positioning device accurately to deliver to the clamp frame bottom to ensure sheet material.

Characteristics of the present utility model are: this is that a kind of being applicable to produced large-scale thermoforming plastic The machinery of goods, its workpiece size are easy to regulate, and with several function synthesizeds together, Make each critical piece flexible structure of this machinery, but the size of workpiece is random, the processing plate The thickness of material is changeable, comprises cleaners and polishes thereby can develop a series of products, and building is floating Carving decoration, furniture, lamp decoration etc.

Claims

1, a kind of thermoforming machine for plastics, by heating plate, the mould frame, Deng composition, it is characterized in that heating plate divides upper and lower two-layer, moving track is arranged at last heating plate bottom, there is chain traction the side, mobile cylinder is arranged below the following heating plate, and there is moving track removable clamping plate frame top, there is conduction chain the side, removable clamping plate frame has adjustable positioning device above on support frame, the clamping cylinder is arranged below.

2, thermoforming machine for plastics according to claim 1 is characterized in that clamping frames and the clamping plate on the removable clamping plate frame passes through to clamp the cylinder clamping plastic plate.
