Abstract
The utility model provides an ejector structure of a real mold plate of a thread stripping mold, which is adaptable to the field of injection molds. The ejector structure comprises a rear mold plate, a rear mold core inlaid on the rear mold plate, a support plate engaged with the lower surface of the rear mold plate and a threaded core arranged inside the rear mold plate and the rear mold core, wherein a first gear is fixedly arranged on the threaded core and is meshed with a second gear, the second gear is connected with a driving part, a T-shaped regulating column is further arranged between the rear mold plate and the support plate, and an elastic part is sleeved on the regulating column. The ejector structure utilizes an regulating nail to regulate a compression distance of a spring sleeved on the regulating column, when opening the mold, the rear mold plate is ejected out via elastic force of the spring while the threaded core rotates to realize thread stripping, and then ejecting rhythm of the rear mold plate and the rotary thread stripping rhythm of the threaded core are consistent, thereby smoothly producing products with threads and resolving the problem that thread profiles of products are easy to be damaged during a demolding process in the prior art.
Description
Technical field
The utility model belongs to the injection mold field, relates in particular to a kind of threaded mold rear pattern plate ejecting structure that takes off.
Background technology
In the existing injection mold industry, the helicitic texture of product is generally by taking off the threaded mold moulding, this concrete course of work of taking off threaded mold is as follows: after the mould die sinking, under the transmission of gear, thread core makes to take off threads turn, and thread core breaks away from direction at product to be fixed, and rear pattern plate was ejected by the ejection system of mould when thread core rotated, thereby finished the production of threaded product.But in actual production process, because mould assembles, the mould temperature changes, produce the influence of factors such as length service time, it is often inconsistent that screw thread rhythm is taken off in the rotation that ejects rhythm and thread core of rear pattern plate, causes the problem of the form of thread of pulling product.
The utility model content
The purpose of this utility model is to provide a kind of threaded mold rear pattern plate ejecting structure that takes off, and is intended to solve the rotation that ejects rhythm and thread core of rear pattern plate of the prior art and takes off the frequent inconsistent problem of screw thread rhythm.
The utility model is to realize like this, a kind of threaded mold rear pattern plate ejecting structure that takes off, comprise rear pattern plate, be embedded at back core rod, the supporting plate that cooperates with described rear pattern plate lower surface on the described rear pattern plate, be located at the thread core in described rear pattern plate and the back core rod, be installed with one first gear on the described thread core, described first gear and one second gears engaged, described second gear is connected with a driving member, also be provided with the adjustable column of a T shape between described rear pattern plate and the supporting plate, be arranged with an elastic component on the described adjustable column.
Described driving member is a motor.
Described elastic component is a spring.
The T shape head of described adjustable column is connected with an adjustment screw.
Described adjustment screw is fixed on the described rear pattern plate.
A kind of threaded mold rear pattern plate ejecting structure that takes off provided by the utility model, come regulating sleeve to be located at the compression distance of the spring on the adjustable column by adjustment screw, during die sinking, when screw thread is taken off in the thread core rotation, elastic force by spring ejects rear pattern plate, the rhythm that ejects that has guaranteed rear pattern plate takes off the consistent of screw thread rhythm with the rotation of thread core, thereby produces threaded product smoothly, the problem of the form of thread of easy-to-draw injured labour product when having solved the demoulding in the prior art.
Description of drawings
Fig. 1 is the schematic diagram that takes off threaded mold rear pattern plate ejecting structure that the utility model embodiment provides.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Consult shown in Figure 1, a kind of threaded mold rear pattern plate ejecting structure that takes off that the utility model embodiment provides, comprise rear pattern plate 1, be embedded at the back core rod 2 on the described rear pattern plate 1, the supporting plate 3 that cooperates with described rear pattern plate 1 lower surface, be located at the thread core 4 in described rear pattern plate 1 and the back core rod 2, be installed with one first gear 5 on the described thread core 4, described first gear 5 and 6 engagements of one second gear, described second gear 6 is connected with a driving member (not shown), also be provided with the adjustable column 7 of a T shape between described rear pattern plate 1 and the supporting plate 3, be arranged with an elastic component 8 on the described adjustable column 7.
In this specific embodiment, described driving member is a motor, and described elastic component 8 is a spring 81, the T shape head of described adjustable column 7 is connected with an adjustment screw 9, described adjustment screw 9 is fixed on the rear pattern plate 1, by screwing in adjustment screw 9 to adjustable column 7, can make further compression spring 81 of adjustable column 7.
The utility model embodiment is provided, and a kind of concrete course of work of taking off threaded mold rear pattern plate ejecting structure is as follows:
(1) behind the injection mold matched moulds, adjustable column 7 is with spring 81 compressions;
(2) after product injection moulding, the moulding, the mould die sinking, 6 rotations of motor-driven second gear, second gear 6 drives first gear 5 and rotates, and owing to first gear 5 is fixed on the thread core 4, thereby thread core 4 also begins rotation, thread core 4 begins to deviate from from product, in the process of thread core 4 rotations, thread core 4 axial orientation control promptly can not be moved to axial direction; When screw thread is taken off in thread core 4 rotations, the compression elasticity of spring 81 discharges, rear pattern plate 1 is ejected, rear pattern plate 1 drives back core rod 2 demouldings, and it is consistent that screw thread rhythm is taken off in the rhythm that spring 81 ejects rear pattern plate 1 and the rotation of thread core 4, after rear pattern plate 1 ejected fully, thread core 4 had also been finished rotation and has been taken off screw thread, thereby produces threaded product;
(3) to take off screw thread rhythm inconsistent when rotation that spring 81 ejects the rhythm of rear pattern plate 1 and thread core 4 occurring, can stop the work of injection mold, with pulling spoon rotation adjustment screw 9, the compression distance of compression or retracting spring 81, with the purpose of the elastic force that reaches regulating spring 81, thereby the rotation that makes spring 81 eject the rhythm of rear pattern plate 1 and thread core 4 is taken off screw thread rhythm and is consistent.
A kind of threaded mold rear pattern plate ejecting structure that takes off provided by the utility model, come regulating sleeve to be located at the compression distance of the spring 81 on the adjustable column 7 by adjustment screw 9, during die sinking, when screw thread is taken off in thread core 4 rotations, elastic force by spring 81 ejects rear pattern plate 1, having guaranteed eject rhythm and the rotation of thread core 4 of rear pattern plate 1, to take off screw thread rhythm consistent, thereby produce threaded product smoothly, the problem of the form of thread of easy-to-draw injured labour product when having solved the demoulding in the prior art.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
