The specific meaning of the above terms in the present invention will be understood in specific cases by those of ordinary skill in the art.
As shown in fig. 1 to 3, the insert 18 is mounted on the mold core 13, and the replacing mechanism 14 is disposed at the bottom of the mold core 13, so as to change the state of the insert 18 to a locked state or a replaced state.
The locking and the release of the insert 18 are realized through the replacement mechanism 14, the working state of the insert 18 is changed, the complicated manual operation is avoided, the quick replacement of the insert 18 is realized, the quick replacement is convenient and quick, and meanwhile, the locking and the release are realized through the replacement mechanism 14, so that the whole operation process of replacing the insert 18 can be carried out with gloves, and the scalding risk caused by residual high temperature after the die works is avoided.
Further, the base 12 is mounted on the fixing plate 11, and a fixing position 15 is designed on the fixing plate 11 for realizing detachable fixed connection with the adsorption equipment.
Further, in the operation of the prior art, the mold core 13 and the insert 18 are often connected through a fastener, and the plastic sucking process is different from the stamping operation, so that the processing of the insert in the stamping die is relatively simple, because the stress condition of each part of the forming surface can be obtained through the simulation calculation of the forming surface of the stamping die, the connecting hole site can be designed at a selected point, the drilling can be performed on the forming surface, and the mold core 13 and the insert 18 or the mold base and other parts are fixedly connected through the connecting hole site and the fastener.
The suction molding process needs to open suction holes on the mold, the design difficulty is increased by adding the mounting holes, and meanwhile, the more holes can form concave parts on the molding surface of the mold core 13, so that the molding quality of the product is affected.
Therefore, the insert 18 is usually fixedly connected to the bottom of the mold core 13 in the conventional process, and the fastener is usually removed from the bottom of the mold core 13, but the bottom of the mold core 13 is a closed cavity surrounded by the base 12 to form a sealing effect on the bottom of the mold core 13, so that the steps of vacuum pumping and the like are performed.
Therefore, the insert is often replaced by lifting the whole die, the mode is time-consuming and labor-consuming, and the long-time suspending operation has potential safety hazard, so that the step is improved later, and an operation window is formed in the base 12, so that an operator can conveniently extend hands into the base 12 to detach the insert 18 through the operation window, but the operation window cannot be opened too much in consideration of the structural strength, and therefore, the requirements on the body type, the hand shape and the like of the operator are also met. Because of the specificity of the adsorption mold, the base 12 must form a sealed cavity, so that the operation window needs to be provided with a sealing plate for sealing, and therefore, when the insert 18 is replaced each time, the sealing plate needs to be detached to operate the fastener on the insert 18, and the like, the fastener is very inconvenient to detach, and often requires several hours to complete the replacement of the insert 18, and when some molds are relatively large, the insert 18 is arranged at the central position of the mold core 13, and at this time, the difficulty is further increased when the operation window is detached, and the operation is more inconvenient.
Further, the replacing mechanism 14 is fixedly connected with the mold core 13 through a mounting plate 17, a mounting groove of an insert 18 is formed in the mold core 13, the mounting plate 17 is fixedly mounted at the bottom of the mold core 13 and is arranged corresponding to the mounting groove, and the insert 18 is slidably arranged in the mounting groove.
Preferably, the mounting plate 17 is connected with the mold core 13 by using threaded fasteners, through holes are drilled in proper places or uniformly distributed on the mounting plate 17, blind holes are drilled and tapped on the mold core 13 at positions corresponding to the through holes of the mounting plate 17 to form threaded holes, and the fasteners such as screws penetrate through the through holes of the mounting plate 17 and are screwed into the threaded holes of the mold core 13 to fix the mounting plate 17.
It is further preferred that the mounting groove of the insert 18 may be in the form of a through profiling groove on the core 13, the limiting of the insert 18 being achieved by means of the mounting plate 17, but the insert 18 is a profiled component, which requires that the surface of the mounting plate 17 facing the insert 18 and the contact portion of the core 13 with the mounting plate 17 are both to a certain degree of machining accuracy, which is sufficient for the mating accuracy of the core 13, the mounting plate 17 and the insert 18.
Still more preferably, the form of the mounting groove of the insert 18 on the mold core 13 may be changed to a non-penetrating, shaped groove with an opening directed upwards for receiving the insert 18, the bottom of the mounting groove being part of the mold core 13, the bottom of the mounting groove being provided with a through hole for receiving the locking and pushing out of the insert 18 by the components on the changing mechanism 14.
Thus, the machining precision of the mounting plate 17 and the matching precision between the mounting plate 17 and the mold core 13 are not required to be too high, and the machining cost is saved. The side wall of the mounting groove on the mold core 13 needs a certain machining precision, the machining precision is easier to consider at the bottom of the mounting groove, and when the upper surface of the mold core 13 is machined, the upper surface of the mold core 13 and the mounting groove can be machined at the same station and the same machining and mounting position.

Still further, the first connector 141 includes a first fastener 1411, a magnetic element 1412, and a bumper 1413, the first fastener 1411 being configured to sequentially overlap and secure the magnetic element 1412 and the bumper 1413 to the insert 18, the bumper 1413 being secured to the outside of the magnetic element 1412 to protect the magnetic element 1412 from impact.
Preferably, the buffer 1413 is made of a magnetic material resistant to high temperature, and not only is the buffer 1413 purely resistant to high temperature, but also the working temperature of the buffer 1413 can be maintained for a period of time during mold processing, and the selected material needs to have the characteristic of not being demagnetized even when working in a high-temperature environment for a long time.
Further, the first fastening member 1411 is a fastening member, preferably a countersunk bolt, and the insert 18 is drilled and tapped to form a threaded hole corresponding to the first fastening member 1411, the magnetic element 1412 is provided with a through hole for accommodating the first fastening member 1411 therethrough, the buffer 1413 is provided with a tapered through hole corresponding to the countersunk bolt feature, and the buffer 1413 and the magnetic element 1412 are sequentially connected in series by using the first fastening member 1411 to be fastened into the threaded hole on the insert 18, so as to complete the fastening and mounting of the first connecting member 141.
The use of countersunk bolts with tapered through holes in the bumper 1413 that correspond to the countersunk bolt features can enable the countersunk bolts to mate with the bumper 1413 more tightly, while the taper has a self-guiding function, facilitating installation.
Further, the second coupling member 142 includes a second fastening member 1421 and a magnetically active member 1422, the second fastening member 1421 being configured to secure the magnetically active member 1422 to the driving member 143. Further, the magnetic force applying member 1422 is a magnetizer, preferably a material that generates a high magnetic attraction force.
The locking and securing of the insert 18 is accomplished by the magnetic attraction force generated between the magnetic element 1412 and the magnetic force acting member 1422. Further, the buffer 1413 is additionally arranged to play a role in buffering, the buffer 1413 adopts rubber and other materials to have a compression space, whether the bottom of the mounting groove is used as the limit of the insert 18 or the mounting plate 17 is used as the limit of the insert 18, the whole replacement mechanism 14 needs to consider the mounting precision, at this time, the matching relation between the magnetic element 1412 and the magnetic acting element 1422 is considered, the distance between the magnetic element 1412 and the magnetic acting element 1422 can be slightly designed into interference fit, and the interference is borne by the buffer 1413, so that the matching precision of the insert 18 and the mold core 13 can be ensured, and the locking function of the first connecting piece 141 and the second connecting piece 142 on the insert 18 can be realized.
Further, the driving part 143 includes a cylinder 1431 and a piston 1432, the cylinder 1431 is fixedly connected with the replacing mechanism 14, one end of the piston 1432 is slidably disposed in the cylinder 1431, and the other end is used for carrying the second connecting piece 142.

By adopting the connecting mode, the sealing effect of the base 12 can be realized only through the sealing joint arranged on the base 12, and the locking and unlocking of the insert 18 can be realized without considering through arranging an operation window on the base 12. The manufacturing cost is saved, the complicated operation flow of operators is avoided, and the operation risk is avoided.
Still further, the cylinder 1431 may be hydraulically or pneumatically controlled, and two connecting pipes 16 are respectively connected to two chambers of the cylinder 1431 to realize driving.
Preferably, the cylinder 1431 uses pneumatic control, the weight of the insert 18 is not too great, the pushing effect is achieved using pneumatic control, and the connection requirements required for pneumatic control are lower than for hydraulic pressure. The procurement costs of the components such as the connecting tube 16 are lower, and the procurement costs of the pneumatic components such as the cylinder 1431 and the piston 1432 can be reduced in consideration of the operating temperature under the same conditions as required.
When the insert 18 needs to be replaced, the connecting pipe 16 is used for controlling the pressurization of a cavity at one side of the cylinder 1431, so that the piston 1432 moves upwards to drive the second connecting piece 142 and the first connecting piece 141 to move upwards, the insert 18 is pushed out of the surface of the mold core 13, an operator can finish replacement operation by wearing a pair of heat-insulating gloves, the insert 18 and the first connecting piece 141 are taken off from the second connecting piece 142, and the insert 18 of another model is replaced and put into the mold core 13 to finish magnetic adsorption of the first connecting piece 141 and the second connecting piece 142. Then, the connecting pipe 16 is used to control the pressurization of the other side chamber of the cylinder 1431, so that the piston 1432 moves downwards to drive the second connecting piece 142 and the first connecting piece 141 to move downwards, and the 1 is retracted to the surface of the mold core 13, so that the locking step is completed.
