Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

As shown in fig. 1-2, the utility model discloses a solve the fixed unstable problem of difficult arranging, fit clearance fixed mode of built-in inserts installation among the current die casting die, provide following technical scheme: the utility model provides an inside inserts fixed knot of mould constructs, includes movable mould core 2, and the embedding sets up in movable mould frame 1, of course, still includes the cover half mould core and the cover half frame that corresponds among the die casting die, and the cover half mould core forms the die cavity with 2 upper and lower locks of movable mould core, and the inside inserts in the scheme of this application mainly set up the position at movable mould core 2.

To the inside product that has bigger fretwork, need set up inserts core 8 in the die cavity, in this application, inserts core 8 is vertical to be set up in movable mould core 2, inserts core 8 runs through whole die cavity, as the fashioned key part of product, still need set up inserts 6 in the die cavity, the setting is in the outside of inserts core 8, inserts 6 and inserts core 8 are the separation, need install inserts 6 on the assigned position in inserts core 8 outside before the mould shaping, this just involves inserts 6's installation and fixed problem, because inserts 6 all is the die cavity around, need fill the raw materials, so can't set up fixed knot and construct, the scheme of this application has just utilized inserts core 8's inner space.

Specifically, a movable rod 9 is arranged, the movable rod 9 is inserted into a central hole at the lower part of an insert core 8 from bottom to top, the movable rod 9 can move up and down in the central hole, the moving range can be set to be smaller, at least two through holes 11 communicated with the central hole are transversely arranged at the position, corresponding to the insert 6, in the insert core 8, the through holes 11 are uniformly distributed around the central hole, the movable pins 7 are arranged in the through holes 11, when the movable rod 9 moves upwards, the movable pins 7 are ejected outwards to support the insert 6, therefore, when the movable pins 7 are ejected outwards, the insert 6 can be synchronously supported, the relative positions of the insert 6 and the insert core 8 cannot be changed, the fixing of the insert 6 is realized, when the mold is opened, the movable rod 9 moves downwards, the movable pins 7 can move freely, and the insert 6 cannot bear the internal supporting force, it can also be removed relatively easily from the insert core 8, but of course the insert 6 is also relatively easy to install in this state.

Preferably, the two through holes 11 are symmetrically arranged on two sides of the upper end of the central hole, the two movable pins 7 can support the insert 6 with a smaller diameter, and for a die with a larger diameter of the insert 6, the three through holes 11 can be arranged, and the three movable pins 7 can simultaneously support the insert 6, so that the insert 6 is prevented from shaking.

In order to convert the upward movement of the movable rod 9 into the transverse movement of the movable pin 7, a conical surface 10 or an inclined surface corresponding to the movable pin 7 is arranged on the side wall of the upper end of the movable rod 9, when the number of the movable pins 7 is large, the conical surface 10 can be used for contacting one end of the movable pin 7, when the number of the movable pins 7 is only 2 or 3, the inclined surface can be arranged at the corresponding position on the movable rod 9, and the movable pin 7 can be horizontally ejected out by contacting the inclined surface with the movable pin 7.

In order to prevent the movable rod 9 from rotating when moving, a guide groove may be formed in the side wall of the movable rod 9, one end of the movable pin 7 may be inserted into the guide groove, and the bottom surface of the guide groove may be an inclined surface.

As a driving scheme of the movable rod 9, the lower end of the movable rod 9 penetrates through the top plate 3 at the lower part of the mold to be connected with the upper jacking oil cylinder 4, the upper jacking oil cylinder 4 is installed on the sealing bottom plate 5 of the mold, the movable rod 9 can be directly driven to move through the upper jacking oil cylinder 4, the movable distance of the movable rod 9 is required to be shorter, the upper jacking oil cylinder 4 with a smaller volume can be arranged, the space between the sealing bottom plate 5 and the top plate 3 of the mold can be used for installation and setting, the oil cylinder can be prevented from being installed on the outer side of the mold, and the size of the mold is reduced.

Of course, an oil cylinder can be arranged on the outer side of the mold, an extension rod of the oil cylinder is transversely connected with a push plate with an inclined surface, the movable rod 9 is in contact with the inclined surface of the push plate, and the movable rod 9 can move up and down through the transverse movement of the push plate, so that the movable rod 9 can be driven in various ways and can be selected and adjusted as required.

The utility model has the advantages of simple structure, effectively utilized the inner space of inserts core, through setting up movable rod and removable pin, can make the removable pin carry out radial movement through the top of movable rod, prop the inserts, realize fixing the inserts at die-casting fashioned in-process, the placing of inserts is also convenient more easily, thereby controlled effectively because of cracking inserts and inserts string scheduling problem, the time of placing the inserts has been saved, the production beat has been promoted, the disability rate of inserts and product has been reduced, and the work efficiency is improved.

It should be noted that all directional indicators (such as up, down, left, right, front, and back) in the embodiments of the present invention are only used to explain the relative position relationship between the components, the motion situation, and the like in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indicator is changed accordingly.
