Chamber and top plate corresponding with injection molding machine top rod position are movably arranged on the needle plate of accommodating secret room in the middle part of dynamic model group and connect with needle plate
It connects and is penetrated through upwards to the thimble of dynamic die set top type chamber, the top plate is equipped with multiple top rods matched with the top rod
Hole is fixed by the connecting rod connection, and is equipped between the top plate top surface and the accommodating cavity between the top plate and needle plate
Reset spring.Wherein, the push plate on moving template is mostly the integral structure of multi-chamber, since to generate heat expansion cold for injection mold
Contracting, this surface area larger structure is easy to produce biggish deformation after long-term use, influences service life, and is unfavorable for tieing up
It repairs, causes further increasing for production cost.
Utility model content
Therefore, in view of the above-mentioned problems, the utility model provides, a kind of service life is long, the split type ledal-pushing machine of stable mold
Structure.
In order to achieve the above objectives, the utility model is achieved through the following technical solutions:
A kind of split type rushing board mechanism of mold, including the dynamic model group and cover half group being mutually adapted, the dynamic model group includes
Moving template, backing plate and the bottom plate from top to bottom set gradually is provided with more than two push plates on the moving template, described to push away
A plurality of die cavitys when offering molding on plate with the sealing cooperation of cover half group, the lower end surface of the backing plate are equipped with Ejector Retainer Plate,
A plurality of thimbles for product ejection die cavity after being molded are installed, the thimble is threaded through the pad on the Ejector Retainer Plate
On plate and moving template.
Preferably, top rod hole is offered in the middle part of the bottom plate, the lower end surface of the Ejector Retainer Plate offers a plurality of positioning
Column offers the locating slot with positioning column cooperation on the bottom plate.
Preferably, a plurality of inner groovies is offered on the Ejector Retainer Plate of gap between each thimble.
Preferably, the guide pin for preventing the Ejector Retainer Plate offset is additionally provided on the Ejector Retainer Plate.
By using preceding solution, the beneficial effects of the utility model are: the utility model is pushed away using split type
Plate can reduce manufacturing cost compared to the push plate of previous integral type, small in size to be more conducive to processing and daily maintenance, in portion
It can reduce maintenance difficulty when dividing push plate damage, while when some independent position is damaged, can accomplish simply to dismount, improve inspection
Repair efficiency.
Detailed description of the invention
Fig. 1 is the decomposition texture schematic diagram of the utility model embodiment；
Fig. 2 is the schematic cross-sectional view of the utility model embodiment.
Specific embodiment
The embodiments of the present invention is described in detail below with reference to specific embodiment, whereby such as to the utility model
What applied technology method solves technical problem, and the realization process for reaching technical effect can be fully understood and implemented.
Embodiment
Referring to Figure 1 and Figure 2, the split type rushing board mechanism of a kind of mold, (by taking plastic cup with cover as an example) include being mutually adapted
Dynamic model group 1 and cover half group 2, the dynamic model group 1 includes the moving template 11, backing plate 12 and the bottom plate that from top to bottom set gradually
13, on the moving template 11 setting there are two push plate 14, when offering molding in the push plate 14 with the sealing cooperation of cover half group
The lower end surface of eight die cavitys 15 (being uniformly arranged four in each push plate 14), the backing plate 12 is equipped with Ejector Retainer Plate 16, the top
16 thimbles 17 for product ejection die cavity 15 after being molded are installed, the thimble 17 is threaded through described on needle bottom plate 16
On backing plate 12 and moving template 11.Herein due to by taking plastic cup with cover as an example, cup lid and cup body are integrated, therefore each die cavitys
15, which are required to two thimbles 17 of setting, ejects product, and the number of thimble 17 can be arranged according to the difference of product herein.
In the present embodiment, top rod hole 131 is offered in the middle part of the bottom plate 13, pushes up rod described in the center face of Ejector Retainer Plate 16
The position in hole 131, the lower end surface of the Ejector Retainer Plate 16 offer a plurality of positioning columns 161, offered on the bottom plate 13 with
The locating slot 132 that positioning column 161 cooperates.At runtime, Ejector Retainer Plate 16 is protected under the action of locating slot 132 and positioning column 161
The stable of up and down direction is held, avoids generating shaking as far as possible.
Specifically, offering a plurality of inner groovies on the Ejector Retainer Plate 16 of gap between each thimble 17
