Abstract
The invention discloses a high-precision plastic suction mould. The high-precision plastic suction mould comprises an upper mould and a lower mould, wherein a plastic suction mould cavity is formed after the moulds are assembled; air extraction hole structures are arranged from the top to the bottom in the upper mould; an electric heating plate structure is arranged in the lower mould and is capable of moving up and down in the plastic suction mould; and the movement of the electric heating plate is controlled by a pushing rod at the lower part. The high-precision plastic suction mould disclosed by the invention is reasonable in structural design and unique in function; the electric heating plate structure arranged in the lower mould is capable of effectively heating plastic sheets and moving up and down relative to the plastic suction mould cavity so as to adjust the inner pressure of the plastic suction mould cavity, enhance the adhesion between the plastic sheets and the upper mould and meet the production requirements of plastic suction products with relatively complex structures, so that the high quality of finished plastic suction products is effectively ensured.
Description
Technical field
The present invention relates to a kind of plastics suction mould, particularly relate to a kind of high accuracy plastics suction mould obtaining high-quality Blister product, belong to plastic suction forming apparatus accessory technical field.
Background technology
Plastic suction forming apparatus is again thermoplastic shaping machine, its operation principle is: the pull of vacuum utilizing vavuum pump to produce is by thermoplastic plastic sheet materials such as PVC, PET, PETG, APTT, PP, PE, the PS after thermoplastic, make the vacuum (-tight) housing of various shape through mould plastic uptake, or attached to the surface in various shapes.Plastic uptake technique can be divided into thin slice plastic uptake and sheet plastic uptake according to the thickness of sheet material.
The mould that plastic suction forming apparatus uses is called plastics suction mould, and it is by after open and flat plastic sheet heating deliquescing, adopts vacuum suction in the surface of plastics suction mould, obtains plastic packing product through cooling aftershaping.The structure of existing plastics suction mould is mostly: offer aspirating hole structure in patrix, and for adsorption plastic sheet material, counterdie is electric heating tube in drier device then, for soft plastics sheet material.But, only rely on patrix to coordinate aspiration pump to implement plastic uptake operation to plastic sheet, between plastic sheet and patrix to be adjacent to power limited, be difficult to the production requirement of the Blister product meeting structure relative complex, have impact on finished product accuracy and end product quality.
Summary of the invention
For the demand, the invention provides a kind of high accuracy plastics suction mould, this plastics suction mould reasonable in design, effect is unique, the electric boiling plate structure arranged in counterdie, while plastic sheet being carried out to effectively heating, also can move up and down by plastic uptake die cavity, relatively to change the pressure in plastic uptake die cavity, effectively improve and be adjacent to power between plastic sheet and patrix, meet the need of production of the Blister product of structure relative complex.
The present invention is a kind of high accuracy plastics suction mould, this plastics suction mould comprises upper die and lower die, plastic uptake die cavity is formed after matched moulds, described patrix arranges aspirating hole structure from top to bottom, described counterdie electric heating tube in drier plate structure, described electric boiling plate can move up and down in plastic uptake die cavity, and the motion of described electric boiling plate is controlled by the push rod of bottom.
In a preferred embodiment of the present invention, described electric boiling plate is made up of housing, electric heating piece, heating and CCU and circuit.
In a preferred embodiment of the present invention, described electric heating piece is embedded at the positive middle part of electric boiling plate, and its area is about 4/5 of electric boiling plate area, and thickness is about 1/3 of electric boiling plate thickness.
In a preferred embodiment of the present invention, described shell material is heat resistant type engineering plastics, and its sidepiece offers annular seal groove structure.
In a preferred embodiment of the present invention, the quantity of described seal groove structure is 2-3.
In a preferred embodiment of the present invention, described seal groove structure is for installing sealing ring, and O type selected usually by sealing ring.
Present invention is disclosed a kind of high accuracy plastics suction mould, this plastics suction mould reasonable in design, effect is unique, the electric boiling plate structure arranged in its counterdie is while carrying out effectively heating to plastic sheet, also relatively can move up and down by plastic uptake die cavity, to regulate pressure in plastic uptake die cavity, between reinforced plastics sheet material and patrix, be adjacent to power, meet the need of production of the Blister product of structure relative complex, effectively ensure that the end product quality that Blister product is good.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is the structural representation of embodiment of the present invention high accuracy plastics suction mould;
In accompanying drawing, the mark of each parts is as follows: 1, patrix, and 2, counterdie, 3, plastic uptake die cavity, 4, aspirating hole, 5, electric boiling plate, 6, push rod, 7, housing, 8, electric heating, 9, seal groove structure.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
