Description

Technical Field

[0001] The utility model relates to the technical field of shaping devices, in particular to a mould shaping device for rubber and plastic processing. Background Art

[0002] The shaping device is a modern word and a special noun. It refers to a device used to further adjust the shape and size of the extruded product and cool it down during the extrusion process when the extrudate has not yet completely cooled. It is also a tool to give rubber and plastic products a complete structure and precise size. Specifically, it refers to the high-pressure injection of heated and melted liquid rubber and plastic into the mold cavity by the injection molding machine, and after cooling and solidification, a molded product is obtained.

[0003] Currently, there are two ways to wait for molds on the market to cool down after injection molding is completed. One is that the machine continues to extrude to maintain a close fit of the mold until the model is cooled down. The other is to lock the mold with bolts and nuts after injection molding until cooling is completed.

[0004] The two mold cooling methods currently on the market both have shortcomings. The first method of continuous extrusion by the machine will occupy the machine and affect work efficiency, and the long-term pressurized state will also damage the machine. The second method of locking the mold with bolts and nuts requires more manpower and time, and the process of removing the bolts will also consume a lot of time. Therefore, a device that can quickly fix and remove the mold is designed. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a mold shaping device for rubber and plastic processing to solve the technical problems of cumbersome fixing and disassembly of traditional molds.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a mold shaping device for rubber and plastic processing, comprising an outer mold and an inner mold, the inner side of the outer mold and the outer side of the inner mold are provided with inclined surfaces, and a limiting groove is provided on the outer side of the outer mold, two groups of threaded rods are provided on one side of the outer mold opposite to the other group of outer molds, and two groups of positioning holes are opened inside the other side of the outer mold, the threaded rods correspond to the positioning holes, a plurality of groups of fixing blocks are provided inside the outer mold, and the fixing blocks are evenly distributed on the outer wall of the positioning holes, and the threaded rods are movably engaged with the fixing blocks.

[0007] By adopting the above technical solution, the inner mold is responsible for shaping the model, and the outer mold is responsible for fixing the inner mold. The inner and outer molds are fixed by inclined surfaces so that they are not easy to fall off when in contact. The limit grooves are used for clamping the machine and subsequent transportation, and the fixation is tighter. The outer mold completes the overall fixation by embedding the threaded shaft into the positioning hole.

[0008] The utility model is further configured that the outer end of the fixing block is connected to a limiting rod, and the outer end of the limiting rod is connected to a limiting spring, the outer end of the limiting spring movably contacts the limiting wheel, and the limiting rod movably penetrates the limiting wheel.

[0009] By adopting the above technical solution, when the threaded rod is inserted into the positioning hole, since one end of the threaded rod is provided with a unilaterally inclined thread, and the fixing block is set to a unilaterally inclined shape, during the process of the threaded rod going deeper, the fixing block is lifted when the thread passes through the inclined contact surface, and the threaded rod continues to go deeper. The limit spring controls the fixing block to reset, and when retracting, the thread contacts the vertical surface of the fixing block to complete the fixation of the threaded rod, and finally completes the fixation of the outer mold.

[0010] The utility model is further configured as follows: a limiting block is provided at the outer end of the limiting rod, and the limiting block is in movably contact with the limiting wheel, a plurality of sets of limiting inclined blocks are provided on the outer wall of the limiting wheel, and the edges of the limiting inclined blocks are in movably contact with the limiting blocks, a limiting shaft is provided at the outer end of the limiting wheel, and the outer end of the limiting shaft is movably engaged with the control wheel, and part of the control wheel rotates through the top end of the outer mold.

[0011] By adopting the above technical solution, the control wheel is rotated so that the limit shaft drives the limit wheel to rotate, the limit bevel block lifts the limit block, and the fixed block is controlled to retreat through the limit rod, thereby releasing the fixation of the threaded rod and completing the disassembly of the outer mold.

[0012] The utility model is further configured that a rotating shaft is arranged outside the limiting shaft, and a transmission belt is movably engaged with the outer wall of the rotating shaft, and the other end of the transmission belt is movably engaged with another group of rotating shaft outer walls on the same side of the outer mold.

[0013] By adopting the above technical solution, the fixed blocks on the same side of the outer mold can be synchronously retracted through the transmission belt to avoid affecting the disassembly of the outer mold.

[0014] In summary, the utility model mainly has the following beneficial effects:

[0015] The utility model uses the inner mold to shape the model, and the outer mold to fix the inner mold. The inner and outer molds are fixed by inclined surfaces, so that the inner and outer molds are not easy to fall off when they are in contact, and are fixed more tightly. The outer mold completes the overall fixation by embedding the threaded shaft into the positioning hole. When the threaded rod is inserted into the positioning hole, since one end of the threaded rod is provided with a unilaterally inclined thread, and the fixing block is set to a unilaterally inclined shape, during the process of the threaded rod going deeper, the fixing block is lifted when the thread passes through the inclined contact surface, and the threaded rod continues to go deeper. The limit spring controls the fixing block to reset. When retreating, the thread contacts the vertical surface of the fixing block to complete the fixation of the threaded rod, and finally completes the fixation of the outer mold. The rotating control wheel causes the limit shaft to drive the limit wheel to rotate, and the limit inclined block lifts the limit block, and the limit rod is used to control the fixing block to retreat, so as to release the fixation of the threaded rod and complete the disassembly of the outer mold. The transmission belt enables the fixing blocks on the same side of the outer mold to achieve synchronous retreat. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The outer end of the fixed block 6 is connected to the limiting rod 7, and the outer end of the limiting rod 7 is connected to the limiting spring 9, the outer end of the limiting spring 9 movably contacts the limiting wheel 10, and the limiting rod 7 movably passes through the limiting wheel 10. When the threaded rod 4 is inserted into the positioning hole 5, since one end of the threaded rod 4 is provided with a unilaterally inclined thread, and the fixed block 6 is set to a unilaterally inclined shape, during the process of the threaded rod 4 going deeper, the fixed block 6 is lifted when the thread passes through the inclined contact surface, and the threaded rod 4 continues to go deeper. The limiting spring 9 controls the fixed block 6 to reset, and when retreating, the thread contacts the vertical surface of the fixed block 6 to complete the fixation of the threaded rod 4, and finally completes the fixation of the outer mold 1.

[0028] A limiting block 8 is provided at the outer end of the limiting rod 7, and the limiting block 8 is in active contact with the limiting wheel 10. A plurality of limiting inclined blocks 11 are provided on the outer wall of the limiting wheel 10, and the edges of the limiting inclined blocks 11 are in active contact with the limiting block 8.
