Description

Technical Field

[0001] The utility model relates to the technical field of mold bases, in particular to a mold base with a mold core that can be quickly replaced. Background Art

[0002] The mold base is the support of the mold, that is, the part that fixes the mold on the injection molding machine to work. The mold base plays the role of supporting, protecting and connecting the key parts of the mold. The mold base does not participate in molding, and its shape will not change with the change of parts, but only related to the size and structure of the parts.

[0003] One product requires a set of corresponding mold cores, so when changing products, the mold cores need to be replaced. Currently, the mold cores of the mold base and the mold base, and the mold base and the injection molding machine are all fixed with screws. When replacing the mold core, you need to wait for the mold base to cool down before you can remove the mold base from the injection molding machine and replace the mold core. After replacing the mold core, when you put the mold base back into the injection molding machine, you need to reposition and re-mold the various layers of the mold structure, which makes the time cost, mold material cost and mold installation cost very high.

[0022] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0023] The utility model provides a mold base with a mold core that can be quickly replaced.

[0024] In the embodiment of the present utility model, a mold base with a mold core 8 that can be quickly replaced, such as Figure 1 to Figure 2As shown, it includes a bottom plate 2 and a top plate 1, cushion blocks 3 are connected to both sides of the bottom plate 2, a push plate 9 and a fixing plate 10 are arranged between the cushion blocks 3, a B plate 4 is installed above the cushion block 3, and an A plate 5 is arranged above the B plate 4, wherein the A plate 5 and the B plate 4 are provided with mounting grooves for installing a core 8 on opposite sides, and the core 8 is respectively installed in the mounting grooves of the A plate 5 and the B plate 4, and a quick release device 7 is provided on one side of the A plate 5 and the B plate 4, and the quick release device 7 can be used for quickly installing and removing the core 8. The structure of the quick release device 7 includes a fixing component 71 and a jacking component 72, and the fixing component 71 may include a through hole 43 provided on the A plate 5 and the B plate 4 and a plug plate installed in the through hole 43, and there is also a plug hole on the side wall of the core 8, and the core 8 is fixed by plugging and unplugging into the plug hole, and a flange for easy pulling out is provided at the end of the plug away from the core 8, and the jacking component 7 is provided at the end of the plug and unplug. The component 72 may include a side hole 44 provided on the A plate 5 and the B plate 4 and a locking block inserted into the side hole 44. A groove is provided on the side wall of the core 8, and the locking block is engaged with the groove of the core 8. A plurality of sets of springs 713 are installed at the bottom of the mounting groove, and the core 8 abuts against the spring 713. When the core 8 is replaced, the engagement between the locking block and the groove is released, and the spring 713 pushes the core 8 out. The top of the A plate 5 is connected to the top plate 1, and the A plate 5 is connected with a guide rod 6. The B plate 4 and the cushion block 3 are both provided with a guide sleeve, and the guide rod 6 is inserted into the guide sleeve of the B plate 4 and the cushion block 3. The core 8 is engaged by the fixing component 71 without being fixed with screws. When disassembly is required, the engaging state can be directly released and quickly removed, and the core 8 is ejected from the mounting groove by the lifting component 72, so that the core 8 can be taken out without disassembling the mold base, thereby realizing rapid replacement of the core 8.

[0025] Preferably, if Figure 3 As shown, the fixing assembly 71 includes a fixing pin 711, and one side of the A plate 5 and the B plate 4 is provided with a through hole 43 connected to the installation groove, and the core 8 is provided with a clamping groove 81. The fixing pin 711 is inserted into each through hole 43 and is set to the clamping groove 81 to clamp with the core 8.

[0026] Furthermore, if Figure 4 As shown, the fixing pin 711 is provided with a clamping block 712, and the inner wall of the through hole 43 is provided with a locking groove 714 and a release groove 715 which are interconnected and set at an angle. When the fixing pin 711 is clamped with the mold core 8, the clamping block 712 is rotated to the locking groove 714 through the release groove 715 to clamp the fixing pin 711; when the fixing pin 711 is separated from the mold core 8, the clamping block slides out through the release groove 715.

[0027] Among them, a spring 713 is sleeved on one end of the fixing pin 711 close to the mold core 8, one end of the spring 713 abuts against the side of the mold core 8, and the other end of the spring 713 is fixedly connected to the fixing pin 711. When the clamping block 712 of the fixing pin 711 rotates to the release groove 715, the fixing pin 711 is popped out, which is convenient and quick.

[0028] Optionally, since the material of the core mold 8 and the material of the mold base are generally different, the thermal expansion coefficients of the two are inconsistent. After the temperature of the mold base rises, the core mold 8 will fit more closely with the A plate 5 and the B plate 4. When replacing the core mold 8, it is usually necessary to cool it down first, so the A plate 5 and the B plate 4 are both provided with multiple heat dissipation holes 42 connected to the mounting grooves to increase the heat dissipation speed.

[0029] Preferably, the side walls of the A plate 5 and the B plate 4 are provided with a plurality of air supply holes 41 connected to the bottom of the installation groove, and the air supply holes 41 are connected to an air pump to quickly cool the A plate 5 and the B plate 4 and facilitate the rapid removal of the mold core 8.

[0030] Alternatively, if Figure 3 As shown, the lifting assembly 72 includes a lift column and a lever 721 connected to one end of a fixed column 722. One side of the A plate 5 and one side of the B plate 4 are provided with side holes 44 connected to the mounting groove. The lever 721 is inserted into the side hole 44. The other end of the lift column connected to the lever 721 abuts against the mold core 8. A support portion 723 is also provided in the side hole 44. The support portion 723 is mainly used to fix and support one end of the lever 721, and to rotatably connect the lever 721 to the support plate. When one end of the lever 721 is lifted upward, the other end is pressed downward, thereby driving the lift column to press the mold core 8 downward so as to take out the mold core 8.
