Specific embodiment
In the following, being described further in conjunction with attached drawing and specific embodiment to the utility model:
A kind of easily demoulding mold as shown in Figure 1, Figure 2 and shown in Fig. 3, including cope plate 10, lower template 20, bottom plate 30 And pin 55, cope plate 10, lower template 20 and bottom plate 30 are from top to bottom set gradually;Cope plate 10 can towards close or It moves far from lower template 20 to be opened or mold, cope plate 10 and lower template 20 are used for the shape forming cavity in molding.
Specific above-mentioned pin 55 is set in lower template 20, and in molding, the reliable plesiotype chamber internal motion of pin 55 is to form Hole location on product, and in die sinking, pin 55 is far from type chamber internal motion.
In addition, the mold that can be threaded off automatically may also include guiding mechanism, which includes the first bootstrap block 51, the Two bootstrap blocks 52, guide post 58, the first ejector retainner plate 56, sliding block 54, take-up housing 53, the first elastomeric element 59 and the second elastic portion First bootstrap block 51 is fixed in the bottom end of cope plate 10 by part 57, and the first bootstrap block 51 is equipped with the first inclined-plane 511, and first tiltedly Face 511 is from top to bottom gradually inclined outwardly.
Take-up housing 53 is slidably mounted in lower template 20;One end of first elastomeric element 59 is connected to take-up housing 53 The other end of rear end, the first elastomeric element 59 is connected in lower template 20, you can be arranged in lower template 20 in the present embodiment Step surface is abutted for the first elastomeric element 59.In die sinking, which, which can provide one, makes take-up housing 53 towards remote First elastic stress of release chamber movement.
Sliding block 54 is fixed in the rear end of take-up housing 53, and the second bootstrap block 52 is installed on the front end of take-up housing 53;Second guidance The rear end of block 52 is equipped with the second inclined-plane;Second inclined-plane with the first inclined-plane 511 for being slidably matched.In this structure basis, first Ejector retainner plate 56 is installed between sliding block 54 and the second bootstrap block 52, and is slidably matched with the top end face of take-up housing 53, i.e., the first top Needle plate 56 can slide between sliding block 54 and the second bootstrap block 52.The back end activity of pin 55 is connected to sliding block 54 and by sliding block 54 rear end stretching is affixed with the first ejector retainner plate 56, and in molding, the front end of above-mentioned pin 55 is used to transport towards by plesiotype chamber It moves and to stretch in type intracavitary.
Second elastomeric element 57 is held between sliding block 54 and the first ejector retainner plate 56, and makes for providing one in die sinking The second elastic stress that one ejector retainner plate 56 is moved far from sliding block 54;The front end of guide post 58 and the first ejector retainner plate 56 are affixed, guidance The back end activity of column 58 is connected to the second bootstrap block 52 and is stretched out by the second inclined-plane;The upper end on the first inclined-plane 511 is equipped with limit Slot 512, the bottom wall of limiting slot 512 are the vertical plane 513 being connected with 511 lower end of the first inclined-plane;The rear end of guide post 58 is used for Limiting slot 512 is protruded into when die sinking and is slidably matched with vertical plane 513.
When using the easily demoulding mold of the utility model, cope plate 10, lower template 20, bottom plate 30 and ejector Structure is mountable on the body of mold, and the driving mechanism on the body of mold can drive cope plate 10 downward towards lower template 20 Movement, when molding, for product in the intracavitary molding of type, pin 55 can protrude into the hole location on the intracavitary shaped article of type.
Detailed process is as follows, and in molding, the first inclined-plane 511 of the first bootstrap block 51 of 10 bottom end of cope plate can be with lower die The second inclined-plane cooperation on the second bootstrap block 52 on plate 20, i.e., during cope plate 10 moves downward, under the first inclined-plane 511 First with the second contact of incline plane, the power being applied on the second inclined-plane can be analyzed to cross force at end, pushes sliding seat to travel forward, makes to inlay 55 front end of needle is towards type chamber internal motion;During cope plate 10 moves gradually downward, guide post 58 can protrude into limiting slot It is abutted in 512 and with the vertical plane of limiting slot 512 513, the second elastomeric element between the first ejector retainner plate 56 and the first sliding block 54 57 are compressed.At the same time, the first elastomeric element 59 between the rear end of take-up housing 53 and lower template 20 also can be compressed.
Hereafter, in die sinking, cope plate 10 is moved upwards, and vertical plane 513 is still abutted with guide post 58 at this time, the second bullet Property component 57 keep compressive state, i.e., pin 55 and product keep relatively motionless at this time, and slide and do integrally in the first elastic portion Mould is first moved back under the first elastic stress effect that part 59 generates when resetting.During cope plate 10 gradually moves upwards, guidance Column 58 slides into the lower end on the first inclined-plane 511, and hereafter guide post 58 can be slided in the lower end on the first inclined-plane 511, the second elasticity Component 57 can reset, and drive pin 55 to exit product, product is enough cooling time at this time, can avoid producing when pin 55 exits Product damage.
Preferably, bottom plate is equipped with the second ejector retainner plate 41 and thimble 42, and the second ejector retainner plate 41 is installed on bottom plate 30 simultaneously It can be moved towards the bottom end close to or far from lower template 20;The bottom end of the thimble 42 is fixed on the second ejector retainner plate 41, top The top of needle 42 is movable to be connected in lower template 20 and for being stretched out in die sinking by the top of lower template 20 with ejecting product. After pin 55 and product are detached from, the second ejector retainner plate 41, the second thimble can be pushed up upwards by the driving structure on mold body Thimble 42 on plate 41 can move upwards, and the top of thimble 42 can be stretched out from the top of lower template 20 is lifted off lower die for product Plate 20 realizes the demoulding of product.
Preferably, the front end of take-up housing 53 is equipped with the first mounting groove, and one end of the first elastomeric element 59 is connected to the first peace The rear wall of tankage;The other end of first elastomeric element 59 is stretched out by the front end of the first mounting groove and is fixed on rear pattern plate, in this way, Prevent the first elastomeric element 59 from occurring beat during by compression or reset, force process is more stable.Likewise, sliding The rear end of block 54 is equipped with the second mounting groove, and one end of the second elastomeric element 57 is connected to the antetheca of mounting groove, the second elastomeric element 57 other end is by the rear end stretching of the second mounting groove and affixed with the first ejector retainner plate 56.In this way, preventing the second elastomeric element 57 Occurs beat during by compression or reset, force process is more stable.
Preferably, the first elastomeric element 59 and the second elastomeric element 57 are spring, and the affixed of above-mentioned spring can be selected Bolt is realized.Certainly, in other cases, blob of viscose, silica gel etc. can be selected in the first elastomeric element 59, the second elastomeric element 57 Other materials with autonomous reset capability are made.
It should be noted that the common driving machine of mold of the prior art can be selected in driving structure in the present embodiment Structure, such as cylinder or oil cylinder.
It will be apparent to those skilled in the art that can make various other according to the above description of the technical scheme and ideas Corresponding change and deformation, and all these changes and deformation all should belong to the protection of the utility model claims Within the scope of.
