Description

Technical Field

[0001] The invention belongs to the technical field of mold processing and relates to an automatic demoulding mold and a method. Background Art

[0002] The lost foam grey cast iron sprue has a regular shape, small volume and size. In order to improve the molding efficiency of the mold, the mold is designed as one mold with 6 pieces. One molding cycle can produce 6 EPS models for grey cast iron sprues. Because it is a hollow sprue with an outer diameter of 42mm, an inner diameter of 16mm, a length of 507.5mm, and a tapered gate at one end, manual feeding is required during the production of each mold, which is divided into 3 areas and completes three punchings. Due to the effect of hot steam, the temperature in the operating room is relatively high, especially in summer, which affects the production rhythm.

[0003] During processing, the existing mold needs to be demoulded manually by core pulling to separate the core pulling with a diameter of 16mm and a length of 520mm from the model. Due to the shrinkage of the model, a large force needs to be applied to the slender core pulling to separate it from the sprue model. Excessive force applied can easily cause damage to the model, and each molding cycle requires 6 manual demouldings, which takes a long time to demould. After taking out the model, the core pulling is inserted into the mold again. Since the core pulling is slender and has a small draft angle, it is not only difficult to pull it out, but also has a low success rate of one-time insertion, which can easily cause deformation and damage to the model, while affecting the production rhythm of each mold and low production efficiency. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that in the prior art, the shaft needs to be manually demolded after model processing is completed, which easily damages the model and takes a long time to demold. Secondly, the core needs to be manually inserted during re-processing, the success rate of core insertion is low, and the model is easily deformed and damaged. An automatic demolding mold and method are provided.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] An automatic demoulding mold comprises an upper mold and a lower mold, wherein the upper mold is arranged on the lower mold, and corresponding mold grooves are provided in the upper mold and the lower mold, and a feed hole is provided on the upper mold, and the feed hole is connected with the mold groove;

[0007] A core pulling drive is provided on the outer wall of the lower mold, the output end of the core pulling drive passes through the interior of the lower mold, the output end of the core pulling drive is connected to a core pulling fixing assembly, a core pulling is provided on the core pulling fixing assembly, the core pulling is placed in a corresponding mold groove, both ends of the core pulling fixing assembly are rotatably connected to a moving block, and the moving block is slidably connected to the lower mold;

[0008] A demoulding mechanism is also provided in the lower mold, one end of which passes through the core-pulling fixing assembly, and the lower end of which passes through the bottom end surface of the lower mold. A demoulding drive mechanism is provided on the outer side wall of the bottom of the lower mold, and the output end of the demoulding drive mechanism is connected to the demoulding mechanism.

[0009] A further improvement of the present invention is:

[0010] The two ends of the core-pulling fixing assembly are provided with rotating shafts, and the rotating shafts are rotatably connected with the moving block;

[0011] A sliding block is arranged at the lower end of the moving block, and a sliding rail corresponding to the sliding block is arranged below the moving block, and the sliding block can slide along the sliding rail.

[0012] The core-pulling fixing assembly comprises a core-pulling fixing plate, and fixing plate connecting blocks are arranged at both ends of the core-pulling fixing plate;

[0013] The rotating shaft is arranged on the fixed plate connecting block;

[0014] The output end of the core pulling driving member is connected to the core pulling fixing plate, and the core pulling is connected to the core pulling fixing plate.

[0015] The core-pulling fixed plate is provided with a slot, a mold-pulling mechanism fixed block is arranged in the slot, and a mold-pulling connection hole is provided on the mold-pulling mechanism fixed block;

[0016] One end of the demoulding mechanism passes through the demoulding connecting hole.

[0017] The demoulding mechanism comprises a top plate, one end of the top plate close to the core-pulling fixing assembly is hinged to one end of the supporting slide plate, and the other end of the supporting slide plate passes through the core-pulling fixing assembly;

[0018] The lower end of the top plate is connected to a guide column, the guide column passes through the bottom end surface of the lower mold, and the output end of the mold-lifting drive mechanism is connected to the guide column.

[0019] The top plate includes a horizontal surface and an inclined surface connected in sequence;

[0020] The horizontal surface is connected to the guide column, and the inclined surface is hinged to support the slide plate.

[0021] The inclined surface and the horizontal surface are integrally formed.

[0022] A plurality of model grooves are arranged in the upper mold and the lower mold, and the plurality of model grooves are connected in sequence;

[0023] The core-pulling fixing assembly is provided with a plurality of core-pulling parts corresponding to the model grooves one by one.

[0024] There are two core-pulling driving members, which are spaced apart along the outer side wall of the lower mold.

[0025] An automatic demoulding method comprises the following steps:

[0026] The upper mold and the lower mold are closed, and beads are filled into the mold groove through the feed hole;

[0027] After the beads are filled, the mold is heated, and after the heating is completed, the mold is cooled;

[0028] After cooling, the mold is opened and the core pulling driving member is started. The core pulling driving member drives the core pulling fixing assembly and the core pulling to move outward until the core pulling fixing assembly cannot move, and then the core pulling driving member is closed.

[0029] The mold-pulling driving mechanism is started, and the mold-pulling driving mechanism drives the mold-pulling mechanism to move upward. During the movement, the mold-pulling mechanism applies power to the core-pulling fixing assembly, so that the core-pulling fixing assembly rotates along the moving block. While the core-pulling fixing assembly rotates, it drives the core-pulling and the processed model to gradually separate from the model groove;

[0030] After the core is pulled and the molded model is completely separated from the model groove, the mold-releasing driving mechanism is turned off, the molded model is removed, and the demoulding is completed.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] The present invention discloses an automatic demoulding mold, wherein a core pulling fixing component is arranged at the end of the core pulling, and the core pulling fixing component can drive the core pulling fixing component to move outward under the action of a core pulling driving component, so that a part of the core pulling is separated from the mold, and the two ends of the core pulling fixing component can be rotatably connected with the moving block, and at the same time the moving block can drive the core pulling fixing component to slide inside the lower mold, and cooperate with the core pulling driving component to facilitate the movement of the core pulling, and a demoulding mechanism is arranged inside the lower mold, and the demoulding mechanism is connected to the core pulling fixing component, and under the action of the demoulding driving component at the bottom, the demoulding mechanism moves upward, and the demoulding mechanism penetrates one end of the core pulling fixing component to apply downward pressure to the core pulling fixing component, and under the action of the pressure, the two ends of the core pulling fixing component The end rotates along the moving block, further driving the core pulling and the model formed outside the core pulling to rotate upward with the core pulling fixing component as the axis and detach from the model groove. At this time, the mold is taken out of the core pulling. Because in the initial stage, a part of the core pulling has been detached from the model under the action of the core pulling driving part, it is more convenient to take out the model at this time. The model can be taken out without applying too much force, and it will not cause deformation and damage to the model. It replaces manual demoulding and shortens the demoulding time. During re-processing, under the limit of the core pulling fixing component and the moving block, when the core pulling is inserted again, the relative position of the core pulling and the model groove will not change, the success rate of insertion is high, the molding quality of the model in the later stage is higher, the labor intensity of workers is reduced, and the production efficiency is high.

[0033] Furthermore, the moving block in the present invention is moved by a slider and a corresponding slide rail. The cooperation between the slide rail and the slider can not only realize the smooth movement of the core pulling fixing assembly, but also limit the moving trajectory of the core pulling fixing assembly well, thereby ensuring the accuracy of the corresponding position of the core pulling and the model groove.

[0034] Furthermore, the top plate in the present invention includes a horizontal surface and an inclined surface. The inclined surface can create a certain height difference between the horizontal surface and the supporting slide plate, which helps the guide column to return to its original position more quickly when it moves up and down driven by the demolding drive assembly.

[0035] Furthermore, in the present invention, the demoulding mechanism and the core-pulling fixing assembly are connected by a demoulding mechanism fixing block, so that the disassembly and installation of the demoulding mechanism are convenient.

[0036] Furthermore, in the present invention, a plurality of model grooves are arranged in the upper mold and the lower mold, so that a plurality of models can be processed simultaneously, thereby improving the processing efficiency.

[0037] The present invention discloses an automatic demoulding method. After the processing is completed, the core pulling can be initially demoulded under the drive of the core pulling driving member, and then the angle and height of the core pulling and the model can be changed in cooperation with the demoulding cylinder at the bottom, so that the model can be smoothly taken out from the core pulling. The method disclosed in the present invention can realize the automatic separation of the core pulling, and manual demoulding is not required, and the model will not be deformed or damaged due to excessive force applied. After completing one processing, the core pulling can be accurately returned to its original position under the drive of the core pulling driving member, and its relative position with the model groove will not be changed. Manual insertion of the core pulling is not required, thereby improving the quality of the model in the later processing, shortening the demoulding time, and improving the processing efficiency.

[0068] The upper mold 1 is buckled onto the lower mold 2 to close the mold;

[0069] Fill the mold tank with beads through the feed hole using an automatic feeding gun 19;

[0070] After filling, the mold is first heated, and then the mold is cooled after heating. After cooling, the mold is opened;

[0071] Start the demoulding cylinder 4, cooperate with the slider 16 and the slide rail, the demoulding cylinder 4 drives the core pulling fixed plate 5, the fixed plate connecting block 15 and the moving block 9 to move outward, and the core pulling fixed plate 5 then drives the core pulling 7 to move outward from the formed model until the slider 16 can no longer move, and then close the demoulding cylinder 4;

Under the limitation of the slider 16 and the slide rail, the core pulling 7 will not change its relative position with the model groove. The molding quality of the model after processing is high. Based on the device provided by the present invention, in actual processing, one person can operate two molding machines and only needs to complete the action of picking up and placing the parts, thereby improving the efficiency of the molding operation and reducing the labor intensity.
