Description
Technical Field
The utility model relates to the technical field of mold processing of plastic products, in particular to a cylinder anti-back mold structure for preventing a sliding seat from backing due to insufficient cylinder force in the processing process.
Background
In the production process of plastic products, because the uniformity and the quantity of the processed pieces are large, batch production is often carried out by using an injection molding machine through a die, and the consistency and the yield of the appearance of the produced products can be ensured, so that the production efficiency is extremely high.
In the production of plastic products, hot runner 11 on upper mold 1 is used to inject molten rubber into the cavity formed by the surrounding upper mold 1 and lower mold 2 (see fig. 1-3), after cooling, upper mold 1 is moved upwards to perform mold opening action, and then the molded product is taken out from lower mold 2. However, if there are protruding or recessed parts perpendicular to the moving direction of the upper mold 1, such as "back-off", on the produced product, the protruding or recessed parts must be completed by the slide blocks 32 on one side of the upper mold 1 and the lower mold 2, the slide blocks 32 are connected with the air cylinders 3 through the air cylinder connecting rods 31 connected with the slide blocks, the movement of the air cylinders 3 causes the slide blocks 32 to generate the movement perpendicular to the moving direction of the upper mold 1, the molding modules fixed at the ends of the slide blocks 32 protrude to one side of the cavity formed after the upper mold 1 and the lower mold 2 are surrounded, and when the injected glue reaches the position of the molding modules, the protruding or recessed product parts perpendicular to the moving direction of the upper mold 1 are formed when the mold is to be opened; however, during the production process, we sometimes find that, when the injection molding machine injects the glue in the molten state, a large injection pressure is required to fill the cavity formed after the upper mold 1 and the lower mold 2 are surrounded, but the pressure also generates a thrust in the opposite direction to the slide block 32 with the fixed molding module, so that the cylinder 3 is forced to retreat, and the molding module fixed at the end of the slide block 32 cannot reach the design position, so that the reject ratio of the product is increased.
Disclosure of Invention
The utility model aims to overcome the defects of the prior art and provides an air cylinder anti-withdrawal die structure.
The utility model adopts the following technical scheme:
The cylinder anti-withdrawal die structure comprises an upper die, a lower die and a cylinder positioned at one side of the upper die and the lower die, wherein a hot runner is arranged on the upper die, the tail end of the hot runner is connected with a cavity formed after the upper die and the lower die are surrounded, a sliding block is connected with the cylinder through a cylinder connecting rod connected with the hot runner, the movement of the cylinder enables the sliding block to generate a movement perpendicular to the movement direction of the upper die, and a forming die block fixedly arranged at the end part of the sliding block protrudes to one side of the cavity formed after the upper die and the lower die are surrounded;
The bottom of the upper die is fixedly provided with a slide seat shovel base near one end of the slide block, which is connected with the cylinder connecting rod, when the cylinder pushes the slide block in place through the cylinder connecting rod connected with the slide seat shovel base, the slide seat shovel base protrudes out of the rear end of the slide block to limit the slide block after the upper die and the lower die are surrounded;
One end of the sliding seat shovel base, which is close to the sliding block, is an inclined surface which is consistent with the sliding block and is inclined outwards;
An adjusting pad is fixed on the inclined surface of the slide block which is inclined outwards;
The material hardness (HRC 58-60) of the adjusting pad is greater than the material hardness (HRC 50-52) of the sliding seat shovel base;
The upper part of the sliding seat shovel base is provided with a bulge, and the outer edge of the bulge is the same as the inner edge of a groove at the bottom of the upper die;
the sliding seat shovel base and the upper die are integrally formed.
According to the utility model, the slide carriage shovel base is added behind the slide block, so that when the injection pressure of the filling sizing material forces the air cylinder to retreat, the slide carriage shovel base is added, the slide carriage is prevented from retreating due to insufficient air cylinder force by utilizing the action of the clamping force of the injection molding machine, the stable production of the slide block in the molding process is ensured, the product quality is ensured, and the production efficiency is improved.

Detailed Description
Referring to fig. 4-8, the cylinder anti-withdrawal die structure comprises an upper die 1, a lower die 2 and a cylinder 3 positioned at one side of the upper die 1 and the lower die 2, wherein a hot runner 11 is arranged on the upper die 1, the tail end of the hot runner 11 is connected with a cavity formed after the upper die 1 and the lower die 2 are surrounded, a sliding block 32 is connected with the cylinder 3 through a cylinder connecting rod 31 connected with the sliding block, the movement of the cylinder 3 enables the sliding block 32 to generate a movement perpendicular to the movement direction of the upper die 1, and a forming module fixedly arranged at the end part of the sliding block 32 protrudes out of one side of the cavity formed after the upper die 1 and the lower die 2 are surrounded; the bottom of the upper die 1 is fixedly provided with a slide carriage shovel base 4 near one end, connected with the slide block 32 and the cylinder connecting rod 31, of the slide carriage shovel base 4, when the cylinder 3 pushes the slide block 32 in place through the cylinder connecting rod 31 connected with the cylinder, the slide carriage shovel base 4 protrudes out of the rear end of the slide block 32 to limit the slide block 32 after the upper die 1 and the lower die 2 are surrounded;
one end of the sliding seat shovel base 4, which is close to the sliding block 32, is an inclined surface which is consistent with the sliding block 32 and is inclined outwards;
An adjusting pad 321 is fixed on the inclined surface of the slide block 32 which is inclined outwards;
The hardness of the material of the adjusting pad 321 is greater than that of the sliding seat shovel base 4;
The upper part of the sliding seat shovel base 4 is provided with a bulge 41, and the outer edge of the bulge 41 is the same as the inner edge of the groove 12 at the bottom of the upper die 1;
The sliding seat shovel base 4 and the upper die 1 are integrally formed.
When the utility model is applied, the upper die 1 and the lower die 2 are clamped, the hot runner 11 on the upper die 1 is used for injecting molten sizing material into a cavity formed by surrounding the upper die 1 and the lower die 2, and the cavity formed by surrounding the upper die 1 and the lower die 2 can be filled with the sizing material under high injection pressure, but the pressure also generates reverse thrust to the sliding block 32 fixedly provided with the forming module, and as the sliding seat shovel base 4 at the bottom of the upper die 1 is propped against the inclined plane at the rear end of the sliding block 32 through the inclined plane which is consistent with the inclined plane of the sliding block 32 when the upper die 1 and the lower die 2 are clamped, the clamping force of the injection molding machine table firmly locks the trend of the sliding block 32 to move backwards, so that the sliding block 32 is prevented from backing in the forming process, and the production of the die is stabilized.
Because the end of the sliding seat shovel base 4, which is close to the sliding block 32, is an inclined surface which is consistent with the sliding block 32 and is inclined outwards, the omnibearing contact of the sliding seat shovel base and the sliding block is ensured; and the thickness of the adjusting pad 321 between the two can be adjusted to ensure that the two are always in the optimal contact position.
As the hardness (HRC 58-60) of the material of the adjusting pad is greater than the hardness (HRC 50-52) of the material of the sliding seat shovel base, the wear-resisting effect is achieved.
