Description
Technical Field
The utility model belongs to the technical field of injection mold, a mould thimble board force return mechanism is related to.
Background
The existing mold ejector plate forced return mechanism comprises an injection molding machine ejector rod, an ejector plate and a movable mold bottom plate with an ejection hole, wherein one end of the injection molding machine ejector rod is in threaded connection with the ejector plate, and the other end of the injection molding machine ejector rod is fixed on the injection molding machine. The technical scheme has the defects that the ejector rod of the injection molding machine needs to be disassembled and assembled when the injection molding machine is used for loading and unloading the mold at each time, the operation is troublesome, the consumed time is long, the efficiency of loading and unloading the mold is low, and the production efficiency is low. The existing forced return mechanism of the ejector plate of the die adopts a spring to reset, the spring is easy to wear after the die is used for a long time, and the reset action is unreliable.
SUMMERY OF THE UTILITY MODEL
The utility model aims at: the utility model provides a return mechanism is forced to mould thimble board aims at solving current mould thimble board and forces return mechanism and all will dismouting injection molding machine ejector pin troublesome poeration when going up the lower mould at every turn to and the not firm technical problem of spring reset.
In order to achieve the above purpose, the utility model provides a technical scheme as follows:
the mold ejector plate forced return mechanism comprises an ejector plate, a pull rod, a movable template and a limiting mechanism arranged outside the mold, wherein the movable template is movably arranged on one side of a movable mold base plate opposite to the ejector plate, one end of the pull rod is fixedly connected with the ejector plate, and the other end of the pull rod is fixed in the movable template; the limiting mechanism comprises a supporting block, a stop block and a cushion block, the supporting block is fixed to the outer portion of the fixed die, the stop block is fixed to the outer portion of the movable die base plate, inserting slots for inserting the supporting block are formed in the stop block, the cushion block is telescopically installed on the side face of the movable die plate through springs, and the cushion block is movably connected with the stop block through an inclined plane structure.
In the technical scheme, during die assembly, the supporting block is in contact with the cushion block, the cushion block and the movable template are pressed towards the ejector rod of the injection molding machine together, after the inclined plane of the cushion block is in contact with the inclined plane of the stop block, the cushion plate is pressed into the movable template by the stop block, after the cushion block completely enters the movable template, the ejector plate completely returns, and the supporting block is inserted into the slot of the stop block until die assembly is completed.
Compared with the prior art, the beneficial effects of the utility model are that: by adopting the forced return mechanism of the mold ejector plate, when the mold ejector plate is used for loading and unloading a lower mold, the ejector rod of the injection molding machine is not required to be disassembled and assembled, the operation is convenient, the consumed time is less, and the production efficiency is high.

Fig. 1 is a sectional view of the mold disclosed in the embodiment in a clamped state;
FIG. 2 is a sectional view showing the opened state of the barb disclosed in the embodiment;
fig. 3 is a sectional view of the half-molded state of the barbs disclosed in the examples.
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.
Examples
Referring to the mold shown in fig. 1-3, the mold comprises a fixed mold plate 10, a movable mold plate 20, a movable mold base plate 30 and an ejector plate 40 which are sequentially arranged, a limiting mechanism is arranged outside the mold, the ejector plate is connected with the movable mold plate through a pull rod 50, one end of the pull rod is fixedly connected with the ejector plate, and the other end of the pull rod is fixed in the movable mold plate; the limiting mechanism comprises a supporting block 60, a stop block 70 and a cushion block 80, the supporting block is fixed outside the fixed die plate 10, the stop block is fixed outside the movable die base plate, a slot 71 for accommodating the supporting block to be inserted is arranged in the stop block 70, the cushion block is telescopically arranged on the side surface of the movable die plate through a spring, and the cushion block is movably connected with the stop block through an inclined surface structure. When the mold is opened, the movable mold reversely retreats, the fixed mold plate is separated from the movable mold plate, and the support block is drawn out from the slot of the stop block. When the die is closed, the supporting block is contacted with the cushion block, and the cushion block and the movable template are pressed together towards the direction of the ejector rod of the injection molding machine; when the inclined surface 81 of the cushion block is contacted with the inclined surface 82 of the stop block, the cushion plate is pressed into the movable template by the stop block; after the cushion block completely enters the movable template, the ejector plate 40 completely returns, and the supporting block 60 is inserted into the slot of the stop block until the mold closing is completed.
The ejector plate forced return mechanism is formed by the ejector plate, the pull rod and the movable template limiting mechanism, the ejector plate forced return mechanism is adopted in the die, and the ejector rod of the injection molding machine only bears the ejection work of the ejector plate, so that the ejector rod does not need to be fixedly connected with the die, the ejector rod of the injection molding machine does not need to be disassembled and assembled when the die is used for loading and unloading the upper die and the lower die, the operation is convenient, the consumed time is less.
Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
