Description
Technical field
The present invention relates to a kind of mold design, more particularly to a kind of injection for surface with the fine and closely woven thread groove of high accuracy
The tailored version processing mold of product.
Background technology
Shooting Technique is a kind of selection process that can meet various nonstandard shaped piece processings, cut compared to tradition,
Milling Machining operating type is rushed, with one-shot forming, the significant advantage being produced on a large scale, however, due to the shape of injecting products
Diversity, injecting products 1 especially as depicted in figs. 1 and 2, its main body includes taking over a business between face 11, the card of chassis face 12 and two
Fine groove connecting shaft 13, and two cards are each provided with the special-shaped boss 111 or groove 112 of axial extension.Especially, the injecting products
Due to applying in precision instruments, its fine groove connecting shaft has precision up to the thread groove 131 of less than 20, can be accurate in subsequent applications
Really favorably accomplish winding operation..
However, the difficulty of processing of traditional such injecting products is larger, and precision cannot be ensured.And due to such note
Molding product often selects high-quality, the raw material of high cost, so easily cause the product rejection of scale, product manufacturing is obtained
Beneficial ratio is difficult to improve.
The content of the invention
In view of the defect that above-mentioned prior art is present, changing for mould precision is moved back the purpose of the present invention is to propose to a kind of injecting products
Kind pattern tool, solves the problems, such as that high precision is ensured.
The purpose of the present invention will be achieved by the following technical programs：A kind of injecting products move back the improvement pattern of mould precision
Tool, corresponding injecting products have the fine groove connecting shaft between face, chassis face and two cards, and two card is each provided with
The special-shaped boss or groove of axial extension, the fine groove connecting shaft have precision up to the thread groove of less than 20, it is characterised in that：Institute
The lower mould for stating improved-type mould is provided with the bottom surface core pulling of lower mode cavity and correspondence chassis face shape；The upper mould of the improvement property mould sets
There are upper cavity and correspondence to take over a business the top surface core pulling of face shape, and both sides between upper and lower die cavity are provided with sliding block, the sliding block
The forming surface with thread groove Accuracy Matching is provided with, and forming surface wraps to form the injection cavity volume of injecting products with upper and lower die cavity.
Further, the outer end of the sliding block is equipped with and moves back membrane module, and the membrane module that moves back is led including oblique guide rod, positioning
To block, horizontal displacement guide pad, the sliding block connects with horizontal displacement guide pad and one is servo-actuated.
Further, the upper cavity is connected to slider top, and water is only done to slider guide in the stroke range of sliding block
Put down to displacement.
Further, water cooling tube is embedded with the upper cavity, lower mode cavity and sliding block, whole water cooling tubes outreach water-cooled pond
And cooling controller.
Using improved-type mould of the invention, its advantage is embodied in：By top, bottom to it is lateral same based on sliding block
Step moves back mould, and makees cooling treatment before die sinking to injection-molded finished, substantially increases the stability that injecting products move back mould, and by essence
Degree ensures the machining accuracy for being transferred to sliding block forming surface, and product die sinking and the difficulty for manufacturing are substantially reduced, and cost performance is superior.
Brief description of the drawings
Fig. 1 is the dimensional structure diagram of injecting products of the present invention.
Fig. 2 is the another to dimensional structure diagram of injecting products shown in Fig. 1.
Improved-type mould of Fig. 3 present invention for injecting products shown in Fig. 1.
Specific embodiment
Hereinafter just accompanying drawing in conjunction with the embodiments, is described in further detail, so that of the invention to specific embodiment of the invention
Technical scheme is more readily understood, grasps.
For prior art to processing such high-precision requirement product mold and technologic difficulty, designer's warp of the present invention
Creativeness research and development simultaneously propose a kind of improved-type mould, the precision for ensureing injecting products with this and finished product quality product rate.
From the point of view of summarizing, as shown in figure 3, the lower mould 2 of this kind of improved-type mould is provided with lower mode cavity 21 and correspondence chassis face shape
Bottom surface core pulling 21；The upper mould 3 of the improvement property mould is provided with upper cavity 31 and correspondence takes over a business the top surface core pulling 32 of face shape, and
And the both sides between upper and lower die cavity are provided with sliding block 41,42.And the sliding block 41 is provided with the forming surface with thread groove Accuracy Matching
411, sliding block 42 is provided with the forming surface 421 with thread groove Accuracy Matching, and two forming surfaces wrap to form injection with upper and lower die cavity
The injection cavity volume of product.
From product injection improve angle from the point of view of, the outer end of the sliding block 41 is equipped with moves back membrane module 5.This moves back membrane module 5 and wraps
Include oblique guide rod 51, positioning and guiding block 52, horizontal displacement guide pad 53, and sliding block 41 connects with horizontal displacement guide pad 53 and one
Body is servo-actuated.To avoid slider displacement from producing influence to Product Precision, the upper cavity 31 of the improved-type mould is connected to sliding block 41 and pushes up
Portion, is oriented to sliding block 41 in the stroke range of sliding block 41 and only do level to displacement.Thus ensure that injecting products are being cooled down completely
Sizing preceding thread groove will not be subject to external force to act on and deform.Similarly, description will be omitted for another side slide.
As the further optimization of above-mentioned technical proposal, it is embedded with the upper cavity 31, lower mode cavity 21 and sliding block 41,42
Water cooling tube 6, whole water cooling tubes 6 outreach water-cooled pond and cooling controller（It is not shown）.It is possible thereby to product injection after the completion of and
Precooled before die sinking, improve the antitypy of Product Precision.
To sum up the detailed description based on diagram embodiment is visible, is embodied using the beneficial effect of improved-type mould of the invention
：Mould is moved back to the lateral synchronization based on sliding block, and makees cooling treatment before die sinking to injection-molded finished by top, bottom, significantly
Improve the stability that injecting products move back mould, and precision guarantee be transferred to the machining accuracy of sliding block forming surface, product die sinking and
