Detailed Description

The following description of the embodiments of the present utility model 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 utility model, but not all embodiments.

Referring to fig. 1-3, a quick-change injection molding die frame comprises a movable die bottom plate 1, a die foot assembly 2 is arranged on the movable die bottom plate 1, a thimble bottom plate 3 is arranged in the middle of the die foot assembly 2, a thimble fixing plate 4 is arranged on the thimble bottom plate 3, a plurality of reset rods and thimbles are arranged on the thimble fixing plate 4, a B plate assembly 6 is arranged on the die foot assembly 2, a die core 7 is arranged on the B plate assembly 6, an A plate assembly 5 is arranged on the die core 7, and a fixed die panel 8 is arranged on the A plate assembly 5.

In this embodiment, a countersink for installing the sprue bush, a circular groove for installing the positioning ring and a plurality of countersinks for installing the fixing screw are formed in the top of the fixed mold panel 8.

In this embodiment, the movable mold bottom plate 1 is provided with a central through hole, a countersunk hole for installing a support column, and countersunk holes for installing a plurality of fixing screws.

In this embodiment, a plurality of fixing holes and a plurality of screw holes for installing fixing screws are formed in the a plate assembly 5, the B plate assembly 6 and the die leg assembly 2.

In this embodiment, for the conventional mold, only one mold core with one size can be installed on one set of mold frames, because the fixed mold plate (a plate) and the movable mold plate (B plate) of the mold frames are integrated mold plates, and the mold core fixing groove machined on the fixed mold plate has determined size, and only one mold core with one size can be installed. The die base is characterized in that the die base is provided with a die base, the die base is provided with a die plate A, a die plate B and die legs, the die base is provided with a die base, the die base is provided with a die plate A, the die base is provided with a die plate B, the die plate B is provided with a die plate B, the die base is provided.

The mold mainly comprises a fixed mold panel, an A plate assembly, a B plate assembly, a mold foot assembly, a movable mold bottom plate, various standard accessories (positioning rings, guide posts, guide sleeves, support posts, reset rods, springs, fixing screws and the like) and the like. In practical application, the staff only needs to design and process the mold core (mold core and cavity), the ejector pin fixing plate, the ejector pin bottom plate and standard accessories (such as a sprue bush, an ejector pin and the like) according to the plastic part, and can assemble a complete set of mold by using the components of the quick-change injection mold frame, so that the functional effect that one set of mold frame is suitable for multiple types of mold cores is achieved, and the quick-change injection mold frame can be used for multiple times, so that the processing cost and the processing time are greatly saved.

In addition, the A plate component, the B plate component and the die leg component are of L-shaped structures and are mutually independent, four corners can be used as supports, and the die core is fixed through side mounting screws, so that the design has the following advantages: the A plate component, the B plate component and the die leg component are mutually independent, and can be better adapted to die cores with different sizes; the L-shaped mold leg assembly is more stable and reliable than the L-shaped mold leg assembly in the market, and the center of the mold frame is provided with a support column, so that the stability and the rigidity of the mold are further ensured; the B plate component is arranged at four corners of the mold core (mold core), and the middle part is kept away from the air, so that the design and the installation of the ejection system are not affected.

Compared with the traditional die carrier, the quick-change die carrier has the advantages of fewer parts, convenient disassembly and assembly and wide application range, and the same quick-change die carrier can be suitable for die cores with different sizes, and a new die can be assembled by only replacing the die cores.

The quick-change die carrier is material-saving, efficient and high in adaptability, can effectively solve the problem of teaching pain, and is worthy of being explored and popularized by enterprises.

The side core pulling mechanism can be additionally arranged on the quick-change die carrier, so that the quick-change die carrier can be assembled with more types of die cores to produce various types of plastic products, and the application range is wider.

The foregoing is only a preferred embodiment of the present utility model, but the scope of the present utility model is not limited thereto, and any person skilled in the art, who is within the scope of the present utility model, should make equivalent substitutions or modifications according to the technical scheme of the present utility model and the inventive concept thereof, and should be covered by the scope of the present utility model.
