Description
Technical Field
The utility model relates to a mould field, a double-deck alternately slider is loosed core for plastic mold specifically says so.
Background
As shown in figure 1, the prior art injection molding product is a technical problem of forming and core pulling in injection molding of plastic products corresponding to a dental floss holder category, and the product mainly comprises a wire storage bin, a wire outlet, a wire take-up port and the like in structure. The wire outlet needs to rotationally loose core and demould, and the wire take-up port needs to linearly loose core and demould; the two-direction core pulling and demolding are difficult to complete on a mold due to size and structure limitations. Due to the limitation of the structure of the wire inlet and outlet, the core can not be pulled by adopting an integral slide block core pulling mechanism in the design and manufacture of the injection mold.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a plastic mold is with double-deck alternately slider is loosed core, and fundamentally has solved above-mentioned problem, and it has advantages such as simple structure is compact, convenient to use is swift.
In order to achieve the above purpose, the utility model provides a following technical scheme: this plastic mold looses core with double-deck slider that intersects includes cover half subassembly, dowel plate, and its technical essential is: the fixed die assembly comprises a second fixed die and a first fixed die which are sequentially arranged on the force transfer plate, the force transfer plate and the second fixed die are supported and limited through a plurality of first fixed die assemblies, the second fixed die and the first fixed die are limited through a second positioning assembly, and a central positioning hole penetrates through the center of the fixed die assembly; a bracket is arranged on one side of the fixed die assembly, the cylinder body is assembled on the bracket through a connecting plate, a guide rail is arranged on the bracket, an upper slide block positioned on the guide rail is limited on a piston rod at the output end of the cylinder body through an upper slide block guide pillar, and a second insert core is arranged on the upper slide block; the rack is meshed with the lower sliding block, an arc-shaped first embedding core is arranged on the lower sliding block, and the rack is connected with another driving system through a rack guide post.
The utility model has the advantages that: the bracket is arranged on one side of the fixed die assembly, so that the cylinder body is conveniently arranged on the bracket. Through the control cylinder body and an additional driving system (not shown in the figure), in the die opening process, the upper sliding block and the lower sliding block can simultaneously drive the first insert core and the second insert core to respectively exit in a vertical and rotating mode. The unique structure of the upper sliding block and the lower sliding block ensures that the upper sliding block and the lower sliding block slide out in different lines and do not interfere with each other, the contour forming of a product inlet and outlet port is ensured, and the surface of the product is ensured to be complete and free of defects.

Detailed Description
The following describes the present invention in detail with reference to fig. 1 to 6 by way of specific embodiments. The double-layer crossed slide block core pulling device for the plastic mold comprises a fixed mold component and a dowel plate 4. The fixed die assembly comprises a second fixed die 3 and a first fixed die 2 which are sequentially arranged on a force transmission plate 4, the force transmission plate 4 and the second fixed die 3 are supported and limited through a plurality of first positioning assemblies 21, the second fixed die 3 and the first fixed die 2 are limited through a second positioning assembly 22, and a central positioning hole 23 is formed in the center of the fixed die assembly in a penetrating mode; one side of the fixed die assembly is provided with a support 5, the support 5 is assembled with the cylinder body 1 through a connecting plate 53, the support 5 is provided with a guide rail 51, the piston rod 52 at the output end of the cylinder body 1 is limited on an upper slide block 7 positioned on the guide rail 51 through an upper slide block guide post 71, and the upper slide block 7 is provided with a second insert 73; the rack 8 is engaged with the lower slider 6, the lower slider 6 is provided with an arc-shaped first insert 72, and the rack 8 is connected with another driving system (not shown in the figure, and a cylinder body can be used) through a rack guide post 81.
The utility model relates to a cross slider structure, it includes top shoe and lower slider, and the lower slider is cross state in the below of top shoe, and top and bottom slider is separately with the slide work of difference during the die sinking, and each other does not influence, accomplishes the product and looses core the effect. The upper and lower sliding blocks are driven by the inclined guide post or the oil cylinder to complete respective actions.
The working process of the above embodiment comprises the following steps:
step 1), after die assembly and injection molding, opening a fixed die, and enabling an upper sliding block guide post to go upwards to drive an upper sliding block to loose a core; meanwhile, the rack guide post moves upwards to drive the rack to move, and the lower sliding block is driven to rotate to loose the core.
And 2), when the upper and lower sliders are withdrawn from the product, the mold ejection system works to eject the product.
And 3), closing the die by fixing the die, and starting the next injection molding process.
