Description

Technical Field

[0001] The invention relates to the technical field of nitrogen cylinders, in particular to a series-type air-cooled nitrogen cylinder seat. Background Art

[0002] Nitrogen cylinder seats are widely used in molds. Generally, the lower mold is equipped with a nitrogen cylinder, which is used to push the upper and lower molds to perform stroke movements to achieve the purpose of opening and closing the mold. When the nitrogen cylinder is assembled and connected to the lower mold, a nitrogen cylinder seat is required. One end of the nitrogen cylinder seat is connected to the lower mold and the other end is connected to the nitrogen cylinder. The nitrogen cylinder is assembled to the lower mold end side of the continuous mold using the nitrogen cylinder seat.

[0003] Most of the existing nitrogen cylinder seats are single-piece designs, and the nitrogen cylinder seats are not concentrated and connected in series for use. When a single nitrogen cylinder is in operation, the force is small, and the upper and lower molds are unevenly stressed during the stroke movement, resulting in poor stability when the nitrogen cylinder seat is connected to the nitrogen cylinder and the lower mold of the continuous mold is in operation and the stroke movement is performed. Moreover, after the nitrogen cylinder seat is assembled with the nitrogen cylinder, the nitrogen cylinder seat is affected by the mold and its own long-term operation, and it is very easy to generate high temperature. The nitrogen cylinder seat without a heat dissipation structure is very easy to malfunction due to high temperature during use. Since the conventional positioning method of the nitrogen cylinder seat is to assemble the body using a single threaded hole and a screw, the position is single during assembly, and the stress point between the body and the connection point is single, making the nitrogen cylinder seat inflexible during assembly and use. Summary of the invention

[0004] The purpose of the present invention is to provide a series air-cooled nitrogen cylinder seat to solve the problem that the existing nitrogen cylinder seats proposed in the above background technology are mostly single single designs, and the nitrogen cylinder seats are not concentrated in series for use. When the single nitrogen cylinder is in operation, the force is small, and the upper and lower molds are unevenly stressed during the stroke movement, resulting in the nitrogen cylinder seat being connected to the nitrogen cylinder and the lower mold of the continuous mold. When the continuous mold is in operation and the stroke movement is performed, there is a situation of poor stability. Moreover, after the nitrogen cylinder seat is assembled with the nitrogen cylinder, the nitrogen cylinder seat is affected by the mold and its own long-term operation, and it is very easy to generate high temperature. The nitrogen cylinder seat without a heat dissipation structure is very easy to malfunction at high temperature during use. Since the conventional positioning method of the nitrogen cylinder seat is to assemble the body using a single threaded hole and a screw, the position is single during assembly, and the stress point between the body and the connection point is single, making the nitrogen cylinder seat inflexible during assembly and use.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present invention can pass screws or bolts through the plate hole at the top of the mounting plate to connect the bottom end of the lower mold of the continuous mold with the top of the mounting plate, so as to achieve the effect of assembling the mounting plate and the lower mold of the continuous mold, and the mounting plate is threadedly connected with the screw barrel. The screw barrel is rotated to move up in the vertical direction of the mounting plate, so that the top cover of the screw barrel is connected to the screw or bolt end side passed through the end of the plate hole, thereby reinforcing the assembled screw or bolts.

[0016] 2. The present invention fixes the mounting and the slide plate so that the mounting and the slide plate are integrated. When the screw rod rotatably connected to the main body is rotated, the screw rod drives the slide plate to slide and move along the horizontal direction of the slideway, and the mounting also slides and moves accordingly, thereby achieving the purpose of adjusting the position of the mounting, so that the position of the mounting is adjustable and controllable when the mounting is used for positioning. After the mounting is adjusted to the desired position, the mounting is connected to a support frame in a continuous mold processing environment by connecting screws or bolts through the seat core hole at the end of the mounting, such as connecting the mounting to a processing table for continuous mold processing, thereby achieving the purpose of flexibly assembling the main body from the side end of the main body.

[0017] 3. The present invention uses a threaded connection between a slide plate and a screw rod. When the screw rod is rotated, the screw rod and the slide plate are threadedly transmitted to allow the slide plate to slide with the slideway and slide along the horizontal direction of the slideway, thereby achieving the purpose of adjusting the displacement of the slide plate. Two slide plates are provided and distributed on the left and right sides of the main body, so that the two slide plates can be adjusted from both sides of the main body respectively, thereby achieving the purpose of dual adjustment, control and positioning.

[0018] 4. The present invention can connect the supporting column through the seat hole at the bottom of the bottom supporting seat. When the supporting column rotates, the supporting column and the seat hole are threadedly transmitted, so that the supporting column moves downward along the vertical direction of the seat hole, thereby achieving the purpose of changing the position of the supporting column. The supporting column is fixed to the prism core column, so that the prism core column also moves downward. At the same time, the prism core column is fixed to the disk, so that the disk also moves downward, thereby achieving the purpose of changing the position of the disk. The height of the disk is flexibly adjusted to place the disk in the required positioning environment state, and then a screw is inserted into the disk hole of the disk to connect the disk to the support frame and the support plate in the continuous mold processing environment, thereby achieving the purpose of assembling the main body from the bottom of the main body.

[0019] 5. The present invention is assembled through six disc connecting screws, so that the main body can be assembled from six nodes, making the main body more firm after assembly, and the motor is running to drive the fan blade to rotate. The fan blade generates wind that blows into the seat cavity from the seat groove to cool the seat cavity. The nitrogen cylinder assembled in the seat cavity is cooled and protected by air cooling, and the threaded hole at the bottom of the seat cavity can be connected with screws for assembling and connecting the nitrogen cylinder. The design of the six seat cavities can load six nitrogen cylinders synchronously, so that the six cylinders can be synchronously and serially assembled on the same support. When the top of the support is connected to the bottom of the continuous mold, the six nitrogen cylinders can be synchronously and synchronously operated to push the upper and lower molds of the continuous mold to perform stroke motion, so that the force is more uniform and stable when the continuous mold is in operation.
