Abstract
The utility model discloses a kind of injection forming mold obtaining weldless trace product, comprise the cover half being positioned at below and the dynamic model being positioned at top, it is characterized in that: above cover half, be provided with cooling block, cooling fluid pipeline is provided with in cooling block, being provided with above cooling block can the floating insert of lengthwise movement, cover half is also vertically arranged with at least three guide pillars and at least three stop screws, the equal cross-under in top of guide pillar and stop screw is in floating insert, the nut of stop screw upper end is positioned at the groove of floating insert upper end, stop screw is also socketed with spring, the two ends of spring contact with cooling block with the bottom of floating insert respectively, multiple heating rod is also evenly distributed with at floating insert upper.This is that one is enhanced productivity, and cuts operating costs, the injection forming mold of the obtained weldless trace product that can not impact environment.
Description
Technical field
The utility model relates to a kind of mould, particularly a kind of injection forming mold obtaining weldless trace product.
Background technology
In ejection formation process, due to the reason such as self structure of the layout of gate points, quantity and product, on product, often there is weld mark (weldline) or current mark (Flow mark), affect outward appearance and the quality of product in plastic product.In order to make up the defect of goods, need traditionally to use the mode of application to process, so just be equivalent to add one coating process after injection molding processes, operation is caused to turn over many, inefficiency, the defect such as with high costs, also can cause very large harmful effect to processing environment simultaneously in coating process.
Summary of the invention
The utility model is the above-mentioned deficiency in order to solve existing for prior art, proposes one and enhances productivity, cut operating costs, the injection forming mold of the obtained weldless trace product that can not impact environment.
Technical solution of the present utility model is: a kind of injection forming mold obtaining weldless trace product, comprise the cover half 1 being positioned at below and the dynamic model being positioned at top, it is characterized in that: above cover half 1, be provided with cooling block 3, cooling fluid pipeline 4 is provided with in cooling block 3, being provided with above cooling block 3 can the floating insert 5 of lengthwise movement, cover half 1 is also vertically arranged with at least three guide pillars 6 and at least three stop screws 7, the equal cross-under in top of guide pillar 6 and stop screw 7 is in floating insert 5, the nut 8 of stop screw 7 upper end is positioned at the groove 9 of floating insert 5 upper end, stop screw 7 is also socketed with spring 10, the two ends of spring 10 contact with cooling block 3 with the bottom of floating insert 5 respectively, multiple heating rod 2 is also evenly distributed with on floating insert 5 top.
Described guide pillar 6 is four, and is arranged on symmetrically on two relative limits of cover half 1.
Described stop screw 7 is four, and is arranged on symmetrically on two relative limits of cover half 1.
Compared with the existing technology, tool has the following advantages the utility model:
The injection forming mold of this kind of version, has creatively set up multiple heating rod in floating insert, allows goods coagulation forming under so just can be implemented in the condition of relatively-high temperature, thus eliminates weld mark and the current mark of product surface; This mould can save the coating process in lower traditional processing mode after injection molding processes, accelerates productive temp, thus realizes the object reducing enterprise's production cost, also avoid coating process simultaneously and occurs the situation that surrounding environment pollutes.And its manufacture craft is simple, and cheap for manufacturing cost, therefore can say that it has possessed multiple advantage, be particularly suitable for applying in the art, its market prospects are very wide.
Accompanying drawing explanation
Fig. 1 is the top view of the utility model embodiment.
Fig. 2 is that A-A in Fig. 1 is to sectional view.
Fig. 3 is that B-B in Fig. 1 is to sectional view.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described.As Fig. 1, Fig. 2, shown in Fig. 3: a kind of injection forming mold obtaining weldless trace product, comprise the cover half 1 being positioned at below and the dynamic model being positioned at top, cooling block 3 is provided with above cover half 1, cooling fluid pipeline 4 is provided with in this cooling block 3, then being provided with above cooling block 3 can the floating insert 5 of lengthwise movement, what cover half 1 was gone back longitudinal direction is provided with at least three guide pillars 6 and at least three stop screws 7, and described guide pillar 6 is four, be arranged on two relative limits of cover half 1 symmetrically, similarly, stop screw 7 is also four, be arranged on two relative limits of cover half 1 symmetrically, and the equal cross-under in the top of guide pillar 6 and stop screw 7 is inner in floating insert 5, and wherein the nut 8 of stop screw 7 upper end is positioned at the groove 9 being opened in floating insert 5 upper end, and nut 8 can limit the extreme position that floating insert 5 moves upward, stop screw 7 is also socketed with spring 10, and the upper end of this spring 10 withstands on the bottom of floating insert 5, and the bottom of spring 10 then contacts with cooling block 3, and is also evenly distributed with multiple heating rod 2 on the top of floating insert 5.
The course of work of the injection forming mold of the obtained weldless trace product of the utility model embodiment is as follows:
First heating rod 2 is started, until the temperature in floating insert 5 reach temperature required after, under the effect of forming machine, dynamic model is descending gradually near cover half 1, the lower surface of dynamic model contacts with the upper surface of floating insert 5 and it is pressed down, cover half 1 and dynamic model matched moulds, now spring 10 is compressed, and insert 5 of floating contacts with cooling block 3; In the coolant pipe pipeline 4 of cooling block 3, circulation has cooling fluid, to make to be cast in the product molding in floating insert 5 all the time;
After goods are shaping in floating insert 5, forming machine drives dynamic model up, and insert 5 of floating under the effect of spring 10 ejects, and stop at nut 8 place, insert 5 of now floating disengages with cooling block 3, is taken out by the goods in floating insert 5, waits for injection mo(u)lding work next time.
In the process of cast, because floating insert 5 keeps a relatively high temperature under the effect of heating rod 2, therefore in whole shaping process, product surface there will not be weld mark or current mark, ensure that surface smoothness and the quality of goods; Simultaneously after product molding, insert 5 of floating can disengage with cooling block 3 again at once under the effect of spring 10, prevents because insert 5 of floating contacts with cooling block 3 thermal loss caused.
