Description
Technical Field
The invention relates to the technical field of locking of sliding blocks for injection molding, in particular to a mechanism for locking two sliding blocks for molded products.
Background
In injection molds, a slide mechanism is often used due to structural requirements. As shown in fig. 1, the slide 1a and the slide 1b can form a cavity 2 for molding an article, and the lock block 3 prevents the slide (1 a, 1 b) from being separated due to the slide receiving injection pressure at the time of injection molding. The amount of force with which the locking block 3 locks the slider (1 a, 1 b) depends on the inclination a of the engagement surface of the locking block 3 with the slider. Arrow F1 is the source of locking force: the locking force of the injection molding machine can be achieved by driving the whole body with the sliding block 1a and the sliding block 1b to approach the locking block 3 by the power part of the injection molding machine, or can be achieved by driving the locking block 3 to approach the sliding block 1a and the sliding block 1b by the power part of the injection molding machine, and the common similar structure is a die sleeve group disclosed in the patent number 201820902898.5 at present.
According to the basic principle of mechanics, the locking force F2 of the locking block 3 on the sliding block is equal to the tangent value (tan) of F1 divided by the bevel angle A. If the locking force F1 of the injection molding machine is 100 tons, the oblique angle of the joint surface of the slide block and the locking block 3 is 10 degrees. Then
F2 =f1≡10≡567 ton
If a smaller bevel angle is used, such as a=2°, then
F2 =f1≡tan2≡2864 tons
A relatively small value of a is used in the mold design to obtain a relatively large locking force against the slide.
But is problematic in conventional practice because of the large friction between the latch 3 and the ramp on which the slider engages. Assuming that the friction force is F3, the value of F3 is the positive pressure exerted by the bevel multiplied by the friction coefficient of the two combined materials, assuming that the mold material used is steel, it can be seen from the data that the friction coefficient of steel to steel is 0.15, then
F3 =f2×0.15≡2864×0.15≡429.6 ton
In this case, the mold opening force of the injection molding machine (which is generally smaller than the locking force of the injection molding machine, opposite to the locking force, for separating the lock block from the slide) cannot pull the mold open. This is currently a ubiquitous situation. The slope of the interface between the slide and the lock block of conventional mold designs typically uses a relatively large angle (7.5 degrees or more. Commonly known as a friction angle) to ensure that the injection mold can pull the locked mold apart. If the locking force is required to be increased, the power part of the injection molding machine can be changed to be of a larger specification or power, and the cost is necessarily increased.

Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1-8, a locking mechanism is suitable for two sliders (1 a, 1 b) that can be moved closer to each other and form a cavity therebetween for molding a product, each slider has an inclined joint surface 101 on a side thereof away from the other slider, and the joint surfaces 101 are inclined toward the same side and are inclined so that the two joint surfaces are gradually moved closer to each other.
In one embodiment, at least one of the slides contains the fittings required to perform the molding process, such as injection molding nozzles, injectors, preheating devices, etc. In further embodiments, either slide has at least a runner or a gate cavity in communication with the mold cavity 2 to enable flow into the mold cavity for molding of the article. These arrangements are known to those skilled in the art and thus are not further described or illustrated.
The slides may be both movable or one of the slides may be fixed and the other may be movable so that both slides may perform the closing of the mold cavity and the opening of the mold cavity.
Both slides may be mounted on the same platform 100, or on different platforms; each sliding block can be driven by one hydraulic cylinder 200, or only one sliding block is driven by one hydraulic cylinder, so that the two sliding blocks can move in opposite directions or move in opposite directions, and the hydraulic cylinders 200 are arranged on the corresponding platforms 100; when it is set to drive only one slide 1a, the other slide 1b should be able to maintain a stable state, i.e., the movable slide 1a and the other slide 1b are brought close together so that the mold cavity 2 for molding the article is formed therebetween, the other slide 1b can support the movable slide 1a from retreating, such as the other slide 1b being fixed to the stage 100.
The locking mechanism comprises a locking block 3, wherein a locking groove 301 is formed in the locking block 3, the locking groove 301 can be placed in a position with a combining surface on a sliding block, and the position with the combining surface on the sliding block is a convex part as shown in fig. 6.
The locking mechanism further comprises a driving assembly 4, wherein the driving assembly 4 is used for making the locking block 3 and the two sliding blocks (1 a, 1 b) close to each other to implement locking, and making the locking block 3 and the two sliding blocks (1 a, 1 b) far away from each other to implement die opening.
As an example, the driving assembly 4 includes a locking hydraulic cylinder 300, and the locking between the locking block 3 and the two sliding blocks (1 a, 1 b) may be that the locking hydraulic cylinder 300 drives the locking block 3 and/or the platform 100 to lock the locking block 3 and the two sliding blocks (1 a, 1 b), and the locking hydraulic cylinder may be configured to drive only the locking block, or may be configured to drive only the platform, or may be configured to drive both the locking block and the platform, and when configured to drive both the locking block and the platform, the locking hydraulic cylinder is mainly configured to change in number of the locking hydraulic cylinders, that is, one locking hydraulic cylinder is commonly configured for both the locking block and the platform.
When configured to only drive the locking blocks, the platform should be able to remain in a steady state, i.e. when the locking blocks are driven to lock the two slides, the platform is able to support the two slides, avoiding rollback. Also, when configured to drive only the platform, the lock block should be able to maintain a stable state, i.e., the lock block is able to maintain locking of the two sliders when the two sliders are driven to be locked by the lock block.
It should be noted that the above-mentioned hydraulic cylinders (including locking hydraulic cylinders) are exemplary, and not absolutely limiting, and may also have similar alternative workpieces, such as a cylinder translation assembly, a motor screw assembly, an electric push rod translation assembly, etc., capable of achieving the same driving speed requirement and driving force requirement, as long as the driving is possible.
Referring specifically to fig. 8, in which accessories required for performing the molding process are hidden, as one embodiment, the driving assembly 4 includes a locking hydraulic cylinder 300 for driving the platform 100, a cylinder body of the locking hydraulic cylinder 300 is fixed on a supporting seat 400a, the platform 100 is connected to a rod of the locking hydraulic cylinder 300, the locking block 3 is fixed on another supporting seat 400b, and after the hydraulic cylinder 200 drives the sliding block 1a to enable the two sliding blocks (1 a, 1 b) to approach the mold cavity 2 for forming the molded product, the locking hydraulic cylinder 300 drives the platform 100 to enable the two sliding blocks (1 a, 1 b) on the platform 100 and the locking block 3 to approach each other, so as to achieve locking.
In other embodiments, it is also possible to implement the movement of the slider only manually, not electronically.
The locking groove 301 has a locking surface 302 corresponding to the joint surface 101, and the locking surface 302 is an inclined surface having the same inclination direction as the joint surface 101 but a smaller inclination than the joint surface 101. A transition assembly is arranged between the locking surface 302 and the joint surface 101, and comprises a transition block 5, an elastic piece 6 and a directional sliding assembly; the transition block 5 has a first mating surface 501 which mates with the locking surface 302 and a second mating surface 502 which mates with the bonding surface 101; the directional sliding assembly is used for connecting the transition block 5 to the locking surface 302 and enabling the transition block 5 to retract along the locking surface 302 towards the locking groove 301/extend towards the outside of the locking groove 301; when the transition block 5 performs retracting movement, the elastic piece 6 is in an elastic deformation state under the coaction of the transition block 5 and the inner wall of the locking groove 301; when the locking block 3 and the two sliding blocks (1 a and 1 b) approach each other, a part (a plane 102 part of the sliding blocks in fig. 3 and 6) on the sliding blocks abuts against a part of the transition block 5 extending out of the locking groove 301, and after abutting against, the transition block 5 performs retracting movement synchronously with the continued approach of the locking block 3 and the two sliding blocks (1 a and 1 b).
By adding the transition block 5 between the lock block 3 and the slider, the slope of the transition block 5 and the lock block 3 is made to have a relatively small slope (slope of the lock face 302), and the slope of the transition block 5 and the slider is made to have a relatively large slope (slope of the joint face 101). As shown in fig. 3, in the initial stage of the locking block 3 to be locked to the slider (1 a, 1 b), the plane 503 of the transition block has already hit the plane 102 of the slider, the slope of the transition block 5 combined with the slider has also hit, but there is a part of gap between the locking block 3 and the plane 102 of the slider, at this time the driving assembly 4 continues to tightly lock the locking block 3 to the slider (1 a, 1 b), the locking block 3 presses the transition block 5 and the slider (1 a, 1 b) through the slope of a small angle contacting with the transition block 5, at this time, a very large locking force is generated to the slider (1 a, 1 b) (the force calculation formula can be compared with that shown in the background section).
When the drive assembly 4 is to open the locking block 3 and the slide blocks (1 a, 1 b), the friction forces experienced by the two inclined surfaces (first and second mating surfaces 501, 502) of the transition block 5 are significantly different due to the slope of the first mating surface 501 mating with the locking surface < the slope of the second mating surface 502 mating with the mating surface. The friction force of the joint surface between the transition block 5 and the sliding blocks (1 a and 1 b) is smaller, so that the driving assembly 4 can separate the locking block 3 from the sliding blocks (1 a and 1 b) only by applying smaller mold opening force.
Preferably, the slope B of the locking surface 302 is 2 ° and the slope C of the engagement surface 101 is 10 °, and the drive assembly 4 can pull the mold open with normal mold opening force in the case of a slide capable of receiving a very large locking force.
When the driving component 4 with the same specification or power is used for locking and opening the die, the locking block 3 and the sliding blocks (1 a and 1 b) can obtain larger locking force and only consume smaller die opening force through the improved locking mechanism, and the power of the driving component can be more fully applied to locking, so that the locking effect is better.
The transition block is preferably made of a material that can withstand high pressures, such as hardened steel, high speed steel, cast iron, and the like.
The directional sliding assembly comprises a T-shaped positioning column 7 arranged on a locking surface 302 of a locking groove 301; the transition block 5 is provided with a wide opening 8a of a T-shaped positioning groove 8,T penetrating through the first matching surface 501 and the second matching surface 502, which is positioned on the second matching surface 502, and a narrow opening 8b of the T-shaped positioning groove is positioned on the first matching surface 501; the vertical part 7b of the T-shaped positioning column sequentially passes through the second matching surface 502 and the first matching surface 501 and then is arranged on the locking surface 302 of the locking groove, and the transverse part 7a of the T-shaped positioning column corresponds to the wide part of the T-shaped positioning groove in space; in the direction of the retraction/extension movement of the transition piece 5 along the locking surface 302, a corresponding slidable gap 500 is provided between the T-shaped positioning post 7 and the inner wall of the T-shaped positioning slot 8.
Preferably, the part of the T-shaped positioning column 7 mounted on the locking surface 302 is provided with external threads, the locking surface 302 is correspondingly provided with a threaded hole, and the T-shaped positioning column is in threaded connection with the locking block.
Preferably, after the T-shaped positioning column 7 is mounted on the locking surface 302, the transverse portion 7a of the T-shaped positioning column does not exceed the wide opening 8a of the T-shaped positioning groove, so as to avoid affecting the stability of the second mating surface and the mating surface.
The number of T-shaped positioning posts 7 on each locking surface 302 can be configured to be different according to the use requirement.
The part of the slide block with the joint surface is placed into the locking groove from the notch of the locking groove; the elastic piece 6 is a compression spring, one stress end of the compression spring is abutted on the inner wall of the locking groove 301 opposite to the notch, and the other stress end of the compression spring is abutted on one side of the transition block 5 opposite to the notch of the locking groove 301. The elastic piece can ensure that the transition block can automatically stretch out under the action of the elastic piece when the locking piece is separated from the sliding block.
In order to avoid displacement of the elastic member 6, the transition block 5 and/or the inner wall of the locking groove 301 are formed with a receiving groove 601 for positioning the elastic member 6, preferably, the receiving groove 601 is disposed on the inner wall of the locking groove 301, so that excessive forming of space on the transition block 5 and reduction of the pressure bearing degree of the transition block can be avoided.
Preferably, when the transition block 5 moves along the locking surface 302 in a retracting manner until the transition block 5 abuts against the inner wall of the locking block 3, the transition block 5 is flat with the outer side surface where the notch of the locking groove on the locking block is located.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
