Description

A kind of diameter adjustable mould for making fiber reinforced plastic barrel

Technical field

The utility model is related to field of compound material, and more specifically, the utility model is related to one kind for making glass The diameter adjustable mould of steel cylinder.

Background technology

The existing mould for making fiber reinforced plastic barrel is monoblock type or the assembled mould of fixed diameter, or uses The cylindrical shell of certain diameter is rolled and held round into by glass fiber reinforced plastic flat plate as the shaping mould for thickening into fiber reinforced plastic barrel further Face.The technics comparing for making fiber reinforced plastic barrel of the mould of fixed diameter is simple, however it is necessary that being equipped with multiple diameter specification Mould and complicated demoulding equipment, invest the more and substantial amounts of place of occupancy.Roll the method for holding round to make with glass fiber reinforced plastic flat plate Fiber reinforced plastic barrel need not invest mould and demoulding equipment, but the loaded down with trivial details efficiency of production process is low, need to expend more artificial And material.

Utility model content

The purpose of this utility model is to solve the above problems, and designs a kind of adjustable mould of diameter to meet fiberglass The needs of cylinder different-diameter specification and it is convenient in demoulding, is achieved through the following technical solutions：

A piece mandrel is set, and paired sliding plate is enclosed within mandrel and can slide axially along mandrel, and each pair sliding plate is some Same position is respectively equipped with the orthodontic screw consistent with mandrel direction and anti-tooth screw, and the positive and negative tooth screw rod of respective amount is screwed in In sliding plate screw recited above, the positive and negative tooth screw rod described in synchronous axial system can make this pair of sliding plate along mandrel axially opposing or Contrary slip.Every sliding plate surrounding fixes some axis pin bases with pin-and-hole in the way of annular array, the axis pin base pin-and-hole Axis is vertical with the axis of sliding plate, and of the connecting rod of some double headed roller pin-and-holes is connected with described axis pin base by bearing pin, institute State connecting rod radially and can rotate around bearing pin, and other end is by bearing pin and the bearing pin being fixed on the section bar with fin Seat connection simultaneously can be rotated around bearing pin.The section bar with fin refer on section bar with length consistent with section bar to section bar The fin that side is stretched out, the axis pin base with pin-and-hole are fixed on the opposite of the fin side of section bar and the pin-and-hole of axis pin base and section bar Longitudinally perpendicular, some section bars with fin are arranged in sliding plate by way of connecting rod and axis pin base are connected with sliding plate with annular array Surrounding, the fin on adjacent two root types material remain that the ring of a part is overlapped to form the approximate face of cylinder.Need to adjust When synchronous axial system positive and negative tooth screw drive each pair sliding plate slide along mandrel is relative or contrary, due to each pair sliding plate correspondence position pin The spacing of the connecting rod connected by axle bed and the connection end of section bar is fixed, then the angle of inclination of connecting rod is changed so that carrying fin Section bar produce radial displacement, the diameter on the approximate face of cylinder formed by overlapped fin also accordingly changes.

The beneficial effects of the utility model are：1) mould diameter arbitrarily can be adjusted to meet glass fibre reinforced plastic cylinder within the specific limits The needs of body different-diameter specification；2) only the diameter of mould need to be turned down during the demoulding and just easily mould can be extracted out.

Description of the drawings

Fig. 1 is the structural representation for making the diameter adjustable mould of fiber reinforced plastic barrel according to the utility model example Figure.

Fig. 2 is the axial direction signal for making the diameter adjustable mould of fiber reinforced plastic barrel according to the utility model example Figure.

The label 1 of in figure is mandrel, and 2 is sliding plate, and 3 is positive and negative tooth screw rod, and 4 is the section bar with fin, and 5 is axis pin base, and 6 are Axis pin base, 7 is connecting rod, and 8 is bearing pin.

Specific embodiment

Example of the present utility model is described below in detail；Below with reference to Description of Drawings example be exemplary, only For explaining the utility model, and it is not intended that to restriction of the present utility model.

Turn next to Fig. 1, the exemplified diameter adjustable mould for making fiber reinforced plastic barrel by mandrel 1, be enclosed within The positive and negative tooth screw rod 3 of screw, the axis pin base 4 for being fixed on sliding plate surrounding, company on paired sliding plate 2 on mandrel, screw-in each pair sliding plate Bar 5, the section bar 6 with fin, the axis pin base 7 being fixed on section bar, bearing pin 8 constitute.The mandrel 1 is rigid long axis, institute State 2 center drilling of sliding plate to be enclosed within mandrel 1 and can slide axially.The sliding plate 2 is paired, and wherein one is provided with orthodontic Screw and another is provided with anti-tooth screw in correspondence position, the positive and negative tooth screw rod 3 screws in screw on sliding plate 2 respectively by each pair Sliding plate is coupled together, the positive and negative tooth screw rod of synchronous axial system then sliding plate relative to or contrary mobile.If the surrounding of the sliding plate 2 is further fixed on The dry axis pin base 4 with pin-and-hole for circularizing array, its pin-and-hole axis are vertical with the axis of sliding plate 2.There is pin at two of the connecting rod 5 Hole, wherein one is connected with the axis pin base 4 being fixed on sliding plate 2 and can be rotated by bearing pin 8, some connecting rods 5 pass through bearing pin 8 and Corresponding axis pin base connection radial on sliding plate 2 is arranged in the surrounding of sliding plate 2.Band is fixed with the section bar 6 with fin The axis pin base 7 of pin-and-hole and pin-and-hole axis is longitudinally perpendicular with section bar 6, the other end of the connecting rod 5 by bearing pin 8 and are fixed on band The connection of axis pin base 7 on the section bar 6 of fin can simultaneously be rotated.During regulation the positive and negative tooth screw rod 3 of synchronous axial system drive each pair sliding plate 2 along The axially opposing or contrary slip of mandrel 1, the connecting rod 5 connected due to the axis pin base 4 of correspondence position on each pair sliding plate 2 and winged On the section bar 6 of plate, the connection end spacing of fixing axis pin base 7 is fixed, then the angle of inclination of connecting rod 5 is changed so that winged The section bar 6 of piece produces lateral displacement.

Fig. 2 is turned next to, some section bars 6 with wing plate are connected with sliding plate 2 by connecting rod 5 and axis pin base 4 and axis pin base 7 Circularize surrounding of the array arrangement in sliding plate 2.The section bar 6 with fin is referred to disconnected consistent with section bar of length on section bar Face is remained for the fin for stretching out one fixed width to section bar side of ring, the fin on adjacent two section bars 6 with fin The ring of a part is overlapped, and fin of all cyclization to array arrangement on the section bar 6 with fin of 2 surrounding of sliding plate forms one , there is radial displacement when all section bars 6 with fin are synchronous in the approximate face of cylinder, then the diameter on the approximate face of cylinder accordingly becomes Change.

While there has been shown and described that example of the present utility model, it will be understood by those skilled in the art that：? These examples can be carried out in the case of without departing from principle of the present utility model and objective with multiple changes, modification, replacement and become Type, scope of the present utility model are limited by claim and its equivalent.
