Description
Technical field
The utility model is related to injection mold field, more particularly, to a kind of secondary ejecting mechanism.
Background technology
In injection mold, in order to can smoothly demould after making formed product, it can all design in a mold various
Mould emptier.
It is as shown in Figure 1 a plastic component structure, 111 structure of plastic is complex, and the edge of medial surface is equipped with more
A partition 112, after plastic 111 is molded, partition 112 is embedded in forming slide, is difficult by plastic by general ejecting mechanism
It is taken out from forming slide, therefore, it is necessary to make improvement to existing ejecting mechanism.
Invention content
The technical problem to be solved by the utility model is to provide a kind of secondary ejecting mechanisms, are intended to make plastic by the mechanism
Smoothly demoulding.
Technical solution is used by the utility model solves above-mentioned technical problem：A kind of secondary ejecting mechanism, including top
Plate, thimble, jacking block, sliding sleeve, caging bolt, mandril and forming slide, the mandril upper end is connect with forming slide, described
Sliding sleeve is coated at jacking block top and the lower end of mandril, and the lower part of the jacking block and the lower end of thimble are set on top plate, described
Thimble upper end penetrate in forming slide, the caging bolt is passed through and jacking block and is spirally connected with the lower end of mandril, the limiting
Bolt is equipped with arc groove 7, and the jacking block top is equipped with the spacer pin being connect with caging bolt, and the spacer pin is stuck in
On the arc groove 7 of caging bolt, by way of twisting caging bolt, move upwards caging bolt, it can be outside by spacer pin
Side is moved out caging bolt, and the jacking block can slide on caging bolt.
It is further improved as the utility model, the jacking block lower part is equipped with stud, is cased with outside on the stud
The spring being connect with sliding sleeve.The setting of spring can allow sliding sleeve to reset.
Compared with prior art, the utility model has the advantage of simple in structure, reasonable design, suitable for complicated
Injection mold.The knockout course of plastic in simple terms：By top plate drive jacking block move upwards, by mandril by forming slide together with
Product ejects upwards together, is then screwed into mandril caging bolt upwards, spacer pin is made to be moved out caging bolt outward,
It allows jacking block upward sliding predetermined stroke on caging bolt, and then thimble can be allowed to eject plastic upwards, plastic is from forming slide
It is detached from.

Fig. 2 is the utility model structure diagram one；
Fig. 3 is the utility model structure diagram two.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention is further described in detail.It should be appreciated that specific embodiment described herein is only explaining this
Utility model is not used to limit the utility model.
As shown in Figure 1 to Figure 3：A kind of secondary ejecting mechanism, including top plate, thimble 1, jacking block 2, sliding sleeve 3, caging bolt 4,
Mandril 5 and forming slide 6,5 upper end of mandril are connect with forming slide 6, and sliding sleeve 3 is coated at 2 top of jacking block and the lower end of mandril 5,
The lower part of jacking block 2 is set on top plate with the lower end of thimble 1, and 1 upper end of thimble is penetrated in forming slide 6, and caging bolt 4 passes through top
Block 2 is simultaneously spirally connected with the lower end of mandril 5, and caging bolt 4 is equipped with arc groove 7, and 2 top of jacking block is equipped with and is connect with caging bolt 4
Spacer pin 8, spacer pin 8 is stuck on the arc groove 7 of caging bolt 4, by way of twisting caging bolt 4, makes caging bolt 4
It moves upwards, spacer pin 8 can be outward moved out to caging bolt 4, jacking block 2 can slide on caging bolt 4.
2 lower part of jacking block is equipped with stud, and the spring 9 being connect with sliding sleeve 3 is cased with outside on stud.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
