Description

Technical Field

[0001] The utility model belongs to the technical field of sole hot pressing, in particular to a heating system of a sole hot pressing mould. Background Art

[0002] Rubber soles refer to soles made of rubber. Rubber sole materials can be roughly divided into natural rubber or synthetic rubber. The advantage of natural rubber is that it is very soft and elastic, suitable for various sports, and plays a shock-absorbing role. Rubber soles are soles made of rubber. The production of rubber soles is produced by using rubber sole molds and a pressing method.

[0003] However, when hot pressing the soles, if the mold is fixed unstably, it may not only result in different qualities of the two finished products, but also increase the difficulty and workload of the staff. It will take more time and energy to adjust the mold to ensure its normal operation. Therefore, we proposed a heating system for the sole hot pressing mold. Utility Model Content

[0004] The purpose of the utility model is to provide a heating system for a hot pressing mold for a sole, which places a lower mold and an upper mold on a fixed plate, and then starts a motor to move the two clamping blocks in relative directions until the two anti-slip plates clamp the lower mold. This system can not only quickly position the lower mold and the upper mold, but also fix them, thus solving the problem that the existing mold fixation is unstable, which may not only result in different qualities of the two molded products, but also increase the difficulty and workload of the staff, and require more time and energy to adjust the mold.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The utility model is a heating system for a hot pressing mold for a sole, comprising a bottom plate, the bottom of the bottom plate is fixedly connected to a support frame, the four corners of the top of the bottom plate are fixedly connected to fixing columns, the outer surfaces of the four fixing columns are fixedly connected to a top plate, an upper mold is arranged under the top plate, the upper mold is rotatably connected to the lower mold by a hinge, the top of the bottom plate is fixedly connected to a fixing plate, the left side of the fixing plate is fixedly connected to a motor, the top of the fixing plate is in contact with a clamping block, and the left side of the clamping block is fixedly connected to an anti-slip plate. The utility model arranges clamping blocks, specifically, places the lower mold and the upper mold on the fixing plate, and then starts the motor to move the two clamping blocks in relative directions until the two anti-slip plates clamp the lower mold, which not only can quickly position the lower mold and the upper mold, but also has a fixing effect on them, avoiding the problem of different qualities of two pairs of soles during hot pressing, but also reduces the workload of the staff, and does not need to frequently adjust the mold.

[0007] Furthermore, the bottom of the lower mold contacts the top of the fixed plate, and a movable groove is provided on the top of the fixed plate. The inner wall of the movable groove is fixedly connected to a limiting ring. The opening of the movable groove allows the two clamps to move under its restriction to prevent them from offsetting during movement.

[0008] Furthermore, the output end on the right side of the motor is fixedly connected to a bidirectional threaded rod through a coupling, the middle part of the bidirectional threaded rod is in contact with the inner wall of the limiting ring, and a threaded hole is provided on the right side of the clamping block. The setting of the limiting ring restricts the bidirectional threaded rod while it rotates, preventing it from being misaligned during rotation.

[0009] Furthermore, the inner wall of the threaded hole is threadedly connected to the outer surface of the bidirectional threaded rod, the number of the clamping blocks is two, and the two clamping blocks are symmetrically arranged with the limiting ring as the center, and the number of the anti-slip plate is two. The setting of the anti-slip plate not only increases the anti-slip effect, but also protects the lower mold.

[0010] Furthermore, a hydraulic cylinder is fixedly connected to the top of the top plate, a push rod is fixedly connected to the bottom output end of the hydraulic cylinder, a lower pressure block is fixedly connected to the bottom of the push rod, a limiting ring is fixedly connected to the bottom of the lower pressure block, and a movable hole is opened on the top of the top plate, and the movable hole is adapted to the push rod. The setting of the limiting ring can make the lower pressure block play a limiting effect when the upper mold is hot pressed to prevent it from displacement.

[0011] Furthermore, a heat transfer oil pump is fixedly connected to the top of the top plate, and the right output end of the heat transfer oil pump is fixedly connected to an oil inlet pipe, and an oil filling groove is opened on the back of the lower pressing block, and the front side of the oil inlet pipe is fixedly connected to the back side of the lower pressing block, and the oil inlet pipe is adapted to the oil filling groove, and the left input end of the heat transfer oil pump is fixedly connected to an oil outlet pipe, and the front side of the oil outlet pipe is fixedly connected to the side of the back of the lower pressing block away from the oil inlet pipe, and the oil outlet pipe is adapted to the oil filling groove. The utility model sets an oil filling groove, specifically, by starting the heat transfer oil pump, the heated heat transfer oil is injected into the oil filling groove through the oil inlet pipe, so that the temperature of the lower pressing block is increased, and then through the continuous starting of the heat transfer oil pump, the heat transfer oil with reduced temperature is re-entered into the heat transfer oil pump through the oil outlet pipe, which not only heats the lower pressing block and facilitates heating of the mold, but also allows the heat transfer oil to be recycled, thereby reducing waste and reducing costs.

[0012] The utility model has the following beneficial effects:

[0013] 1. The utility model sets a clamping block, specifically places the lower mold and the upper mold on a fixed plate, and then starts the motor to move the two clamping blocks in relative directions until the two anti-slip plates clamp the lower mold. This not only can quickly position the lower mold and the upper mold, but also has a fixing effect on them, avoiding the problem of different quality of two pairs of soles during hot pressing, but also reduces the workload of the staff, and does not need to frequently adjust the mold.

[0014] 2. The utility model sets an oil filling tank, specifically, by starting the thermal oil pump, the heated thermal oil is injected into the oil filling tank through the oil inlet pipe, so that the temperature of the lower pressing block is increased. Then, by continuously starting the thermal oil pump, the thermal oil with a lowered temperature is re-entered into the thermal oil pump through the oil outlet pipe, which not only heats the lower pressing block and facilitates heating of the mold, but also allows the thermal oil to be recycled, thereby reducing waste and lowering costs.
