Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.
As shown in fig. 1-4, the utility model discloses a ball type sealing washer preparation mould, it includes cope match-plate pattern 10, lower bolster 20, left side board 30 and right side board 40.
The lower template 20 is provided with a male die 21 matched with the shape of the inner cavity of the spherical sealing ring, and the male die 21 is locked on the lower template 20 through screws so as to be convenient to detach, clean and maintain. An air pipe 211 penetrating through the male die 21 up and down is arranged on the male die 21, an outlet at the upper end of the air pipe 211 is positioned at the top end of the male die 21, the other outlet is arranged at the bottom of the male die 21 and communicated with external compressed air supply equipment, and an opening 22 for connecting the air pipe 211 and the external compressed air supply equipment or allowing a connecting pipeline to pass through is arranged on the lower die plate 20.
The left side plate 30 and the right side plate 40 are oppositely arranged at the left side and the right side of the male die 21, and lower end female dies A1 matched with the shape of the lower part of the outer wall of the spherical sealing ring are arranged on the left side plate 30 and the right side plate 40. The left side plate 30 and the right side plate 40 are connected with the lower template 20 in a sliding manner, so that the formed spherical sealing ring can be well demoulded. Specifically, four placing grooves 24 and four sliding rods 23 are arranged on the lower template 20, the sliding rods 23 are inserted into the placing grooves 24 in a one-to-one correspondence manner, and two sliding ways a2 matched with the sliding rods 23 are arranged on each of the left side plate 30 and the right side plate 40. The slide bar 23 is fixed by being inserted into the placement groove 24, and this arrangement is advantageous in that if the slide bar 23 is broken, it can be easily replaced, and the replacement cost is low.
An upper end female die 11 matched with the upper part of the outer wall of the spherical sealing ring in shape is arranged on the upper die plate 10, and the lower die plate 20, the left side plate 30, the right side plate 40 and the upper die plate 10 are compacted, so that the male die 21, the lower end female die A1 and the upper end female die 11 surround to form a forming space of the spherical sealing ring. Since the left and right side plates 30 and 40 are slidably coupled to the lower mold plate 20 and are defined in the front-rear direction, pressing blocks 12 for closing the left and right side plates 30 and 40 are provided on the left and right sides of the upper mold plate 10, respectively. The pressing block 12 is provided with an inclined surface 121, the left side plate 30 and the right side plate 40 are provided with slopes A4 matched with the inclined surface 121, and the pressing block 12 slowly pushes the left side plate 30 and the right side plate 40 to move towards the middle in the process of pressing the upper die plate 10 downwards. In addition, in order to ensure the mold clamping accuracy, four first positioning pins 13 and four second positioning pins 14 are provided on the upper mold plate 10, first positioning holes 25 that are fitted with the first positioning pins 13 one by one are provided on the lower mold plate 20, and second positioning holes a5 that are fitted with the second positioning pins 14 one by one are provided on the left and right side plates 30 and 40.
Because the utility model discloses a place the film before terrace die 21, lower extreme die A1 and upper end die 11 do not close in advance, through hot melt film recooling shaping ball-type seal circle, the film can not melt the very strong state of mobility, so can consider to set up some exhaust ducts B1 that communicate the shaping space for with the gas outgoing of film hot melt in-process production, reduce the gas pocket in the shaping product, promote product quality. These vent grooves B1 may be provided directly on the surfaces of the upper platen 10, the lower platen 20, the left side plate 30, and the right side plate 40. The air pipe 211 is used for demolding the male die 21 after the spherical sealing ring is molded, the air pipe 211 is connected with a compressed air source, and the spherical sealing ring is separated from the male die 21 after the air pressure in the inner wall of the spherical sealing ring is increased to a certain degree. Although the fluidity of the melted rubber sheet is not strong, the diameter of the air pipe 211 is limited to be not more than 5mm in order to avoid the deformation of the corresponding part of the molded spherical sealing ring caused by the too large aperture of the air pipe 211.
After the ball-type seal ring is formed, the upper template 10, the left side plate 30 and the right side plate 40 need to be separated, the upper template 10 and the lower template 20 can be fixed on a special die table, the upper template 10 can use power equipment, in order to enable the left side plate 30 and the right side plate 40 to slide open more easily, a spring A3 is arranged in a slide way a2 and at one end far away from the male die 21, the spring A3 abuts against the slide rod 23, and a containing hole for containing the spring A3 can be arranged on the side wall of the slide way a 2. When the left and right side plates 30 and 40 are pressed by the pressing block 12, the spring A3 is also pressed, and the reaction force of the spring A3 can provide the separation force compensation of the left and right side plates 30 and 40 after the upper die plate 10 is separated.
The utility model discloses a key lies in, cope match-plate pattern 10, lower bolster 20, left side board 30 and right side board 40 separately set up, through terrace die 21, lower extreme die A1 and the shaping space that upper end die 11 encloses into ball-type seal circle after the combination, through arranging the film in shaping space after the heating melt, ball-type seal circle is made in the recooling design, easy operation is convenient, mode preparation ball-type seal circle through the hot melt film, the finished product gas pocket is few, the quality is excellent.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the present invention.
