Abstract
The invention relates to a mould for producing a plastic injection panel, relating to a mould, in particular to a mould for injection. The mould comprises a stationary module, a mould cavity, a lower press plate and an upper press plate, wherein the periphery of the mould is provided with a stationary module base plate; the stationary module is fixed in the stationary module base plate; the mould cavity is positioned between the stationary module and the lower press plate; both ends of the upper press plate are respectively connected with the lower press plate and the stationary module base plate by using T-shaped guide rails; the lower press plate is matched with the upper press plate by adopting a slope; the lower press plate can only move up and down along the thickness direction of the mould cavity, the upper press plate only moves along a horizontal direction ( perpendicular to the motion direction of the lower press plate), and the lower press plate is driven by the T-shaped guide rails to move up and down; a screw rod is fixed at the tail end of the upper press plate; and a nut positioned on the screw rod is fixed in the stationary module base plate. The invention processes the thickness of the panel as required, pushes the upper press plate to horizontally move along the T-shaped guide rails by using the screw rod so that the pressures of the lower press plate vertically moves under the pressure of the upper press plate, thereby changing the size of the mould cavity; in addition, the panel with required thickness is processed by injecting raw materials into the mould cavity.
Description
Technical field
The present invention relates to a kind of mould, be specifically related to a kind of injection molding mould.
Background technology
In the process of producing injection molding panel, usually produce panel one mold of same thickness, then need to change another set of mould in the time of the different-thickness panel produced, produce the panel of how many kinds of thickness, correspondingly will change how many molds, more need pull down lathe to mould during mold exchange, change core; Also have a kind of common way: i.e. mold exchange not, according to processing request the die cavity of raw materials for production size is done corresponding the adjustment.No matter take which kind of method, all need lathe is taken apart more mold exchange or die cavity, expend a large amount of man power and materials, production efficiency is very low.
Summary of the invention
The invention provides a kind of mould that injection molding panel is used of producing, not only solved a mold and once gone up lathe and just can production obtain the sample problem of required any gauge, but can also guarantee to realize the adjustment of product thickness continuity; But guarantee the production of product thickness repetition.
For realizing purpose of the present invention, technical scheme provided by the invention is:
A kind ofly produce mould that injection molding panel uses by the cover half piece, die cavity, lower platen, top board constitutes, be the cover half backing plate all around, the cover half piece is fixed in the cover half backing plate, between cover half piece and the lower platen die cavity is arranged, the two ends of top board connect lower platen and cover half backing plate with T type guide rail respectively, adopt the inclined-plane to cooperate between lower platen and the top board, lower platen can only be done moving up and down of die cavity thickness direction, top board is then only done horizontal motion (vertical with the direction of motion of lower platen), driving lower platen by T type guide rail simultaneously moves up and down, the tail end of top board is fixed with screw rod, and the tail end of screw rod is fixed with dial, and the nut on the screw rod is fixed in the cover half backing plate.
During use, the thickness of panel machining as required, rotary dial promotes top board by screw rod and moves horizontally along T type guide rail, lower platen was done under the pressure of top board and was moved both vertically this moment, thereby changed the size of die cavity, raw material has been injected die cavity, then processed the panel of desired thickness.
The angle of tiltedly carving of described top board is 2.29 °; The top board angle [alpha] guarantees that less than the self-locking angle of steel and steel lower platen can not be subjected to displacement when injection moulding is produced, thereby the thickness that guarantees product is accurately.

The specific embodiment
The present invention will be further described below in conjunction with accompanying drawing 1 to 2.
A kind ofly produce mould that injection molding panel uses by cover half piece 7, die cavity 8, lower platen 1, top board 2 constitutes, be cover half backing plate 6 all around, cover half piece 7 is fixed on 6 li on cover half backing plate, between cover half piece 7 and the lower platen 1 die cavity 8 is arranged, the two ends of top board 2 connect lower platen 1 and cover half backing plate 6 with T type guide rail 5 respectively, adopt the inclined-plane to cooperate between lower platen 1 and the top board 2, lower platen 1 can only be done moving up and down of die cavity thickness direction, 2 of top boards are only done horizontal motion (vertical with the direction of motion of lower platen), driving lower platen 1 by T type guide rail 5 simultaneously moves up and down, the tail end of top board 2 is fixed with screw rod 3, the tail end of screw rod is equipped with dial 9, and the nut 4 on the screw rod is fixed on 6 li on cover half backing plate.
During use, the thickness of panel machining as required, rotary dial 9 promotes top board 2 by screw rod 3 and moves horizontally along T type guide rail 5, lower platen 1 was done under the pressure of top board 2 and was moved both vertically this moment, thereby changed the size of die cavity 8, inject die cavity 8 with raw material this moment, then processes the panel of desired thickness.
The parameters of this embodiment:
1, the angle of tiltedly carving of top board 2 is 2.29 °:
Set top board 2 in horizontal movement 50mm, lower platen 1 2mm that can move up and down
2, top board 2 design areas are 684cm
2:
Known die cavity 8 maximum pressure 120Kgf/cm
2, the tensile strength 7900Kgf/cm of common iron
2, top board 2 areas are 18.0cm*38.0cm, lower platen 1 area is 50.1cm*30.2cm,
The minimum bearing area of top board 2 areas=182000Kgf ÷ 7900Kgf/cm
2=23cm
2,
3, the adjusting of die cavity 8 degree of depth:
Relative motion by screw rod 3 and nut 4 makes top board 2 produce reciprocating motion, so just, can rotate a circle top board 2 by screw rod 3 and move how many distances, calculate lower platen 4 exactly and move how many distances, again the distance value conversion is presented on the dial, thereby die cavity 8 degree of depth of mould are adjusted accurately.Adopting pitch with screw rod 3 is that 2 fine thread is an example:
Screw rod 3 whenever turns around top board 2 with regard to mobile 2mm, so lower platen 1 displacement S=2/50=0.04mm.Dial 9 quarterings, then dial 9 revolutions 1/4 enclose lower platen 1 with regard to mobile 0.01mm, the thick variation of die cavity material 0.01mm; Dial 9 whenever turns around lower platen 1 with regard to mobile 0.04mm, the thick variation of die cavity 8 material 0.04mm.
