Description
Technical field
The utility model is related to injection mold technical field, more particularly to a kind of injection mold.
Background technology
With the increasingly sophisticated variation of electronic product structure, there is the muscle in preceding mold forming on many electronics plastic cement products
Position.During electronics plastic cement products are molded, die joint mold when be easily restricted, grip suffered by product front mould compared with
Greatly, easily there is die sinking from shape, viscous front mould phenomenon, it is therefore desirable to made in front mould product grip larger part and play roof construction, opened
During mould, product is set to stay in rear mold and deformation of products will not be caused because of viscous front mould.
With reference to shown in Fig. 1 and Fig. 2, when entering sub larger, directly can enter sub- bottom processing one blind hole placement spring；When entering
When son is smaller, it is less with template contacts area to enter sub- bottom surface, and directly doing blind hole and put spring can cause leakage under son.To be added to son
Base contact surface is accumulated, it will usually is increased bullet footstock and square cotter sub- bottom is entered, is connected together footstock is played with son is entered with pin, but
Design cost and machining period increased using which.The production cycle is increased, die cost is increased, causes production efficiency
Reduce.
Utility model content
Technical problem to be solved in the utility model is：A kind of injection mold is provided, the injection mold solves injection
Mini-bomb in mould heads into the unsupported technical problem in sub- bottom.
In order to solve the above technical problems, the technical scheme that the utility model is used is：A kind of injection mold, including front mould
Benevolence, front template, rear cavity and rear pattern plate, the front cavity are fixedly installed in the front template, the rear cavity fixed installation
Son is headed into bullet is slidably fitted with the rear pattern plate, the front cavity, the correspondence bullet heads into the position of son on the front template
Installed mounting hole, be provided with bullet ejection device in the mounting hole, the bullet ejection device has included thimble, the thimble include hanging platform and
Shank, the hanging platform heads into son and leans with the bullet；Spring housing is located at the shank, one end of the spring and the thimble
Hanging platform lean, the other end of the spring leans with the bottom of the mounting hole.
Used as a kind of improved mode, the front template is fixed on front shoe, and the rear pattern plate is fixed with rear fixed plate
Connection.
Used as a kind of improved mode, the rear pattern plate is fixedly connected by support block with the rear fixed plate.
Used as a kind of improved mode, the front shoe is provided with injection machine locating ring.
As a kind of improved mode, guider, the guiding dress are provided between the front template and the rear pattern plate
It is set to guide pillars and bushes.
Use the technique effect acquired by above-mentioned technical proposal for：
Thimble is set between by spring and bullet heading into son, is solved mini-bomb and is headed into the unsupported problem in sub- bottom.
The utility model simple structure, only need to can play support effect using standard thimble interception height, it is to avoid make and play footstock
Processing capacity with square cotter is big, greatly reduces machining period and cost, improves production efficiency.Simultaneously, compared to bullet top
Seat, square cotter device, this device are not limited to by die space, are easier to realize.
Due to being provided with guider between front template and rear pattern plate, guider is guide pillars and bushes, and guider can be
During matched moulds, guiding is played a part of in the relative movement to front template and rear pattern plate.

Specific embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples.
It is jointly shown with reference to Fig. 3 and Fig. 4, a kind of injection mold, including front cavity 4, front template 5, rear cavity 6 and rear mold
Plate 7, front cavity 4 is fixedly installed in front template 5, bullet is slidably fitted with front cavity 4 and heads into son 3, after rear cavity 6 is fixedly installed in
Template 7.The position that corresponding bullet heads into son 3 on front template 5 is provided with mounting hole, and bullet ejection device is provided with mounting hole.
Playing ejection device includes thimble, and thimble includes hanging platform 101 and shank 102, and spring 2 is sheathed on the shank 102 of thimble, bullet
One end of spring 2 leans with the hanging platform 101 of thimble, and the other end of spring 2 leans with the bottom of mounting hole.
Front shoe 10 is provided with the injection machine locating ring 11 for positioning.Front template 5 is provided with guide pin bushing 15, and rear pattern plate 7 is provided with
Guide pillar 14.Guide pin bushing 15 is slided along guide pillar 14 and plays guide effect.Rear pattern plate 7 is fixedly connected with rear fixed plate 9 by support block 8, after
Thimble panel 12 and Ejector Retainer Plate 13 are provided between template 7 and rear fixed plate 9, product thimble and runner ejector pin run through thimble panel
12 and rear pattern plate 7, product thimble and runner ejector pin are clipped between the panel of thimble 2 and Ejector Retainer Plate 13, thimble panel 12 and top
Pin base plate 13 is fixedly connected by fastener, and rear fixed plate 9 is provided with the top rod hole passed through for top rod.
During matched moulds, bullet heads into the hanging platform 101 that son 3 relies on thimble, and thimble compression spring 2, thimble relies on the bottom of front template 5
Portion.
During die sinking, front cavity 4 is separated with rear cavity 6, and spring 2 promotes bullet to head into son 3 by thimble, and bullet heads into son 3
Injecting products are pushed up down from front cavity 4.Avoid grip suffered by product front mould larger, die sinking occur from shape, viscous front mould phenomenon.
An inversion dome pin is put by entering sub- bottom, the hanging platform 101 of thimble is supported into sub- bottom, be arranged outside thimble
Spring 2, the Area of bearing that sub 3 bottom is headed into bullet, the hanging platform 101 and mould of thimble are increased by the hanging platform 101 of thimble indirectly
Plate is contacted, and can prevent from being leaked under son.Thimble model can be selected according to sub- base contact surface product is entered with the internal diameter of selected spring 2
Select, thimble is as far as possible sturdy.Suitable thimble interception height need to be only taken by the structure and can reach effect, eliminate processing bullet
The cumbersome technique of footstock and square cotter, has saved for 80% process time.
The utility model can solve the problems, such as that mini-bomb heads into sub 3 bottom without support by simple structure, simple structure,
Only effect need to be can reach using standard thimble interception height, it is to avoid make the big problem of processing capacity for playing footstock and square cotter,
Machining period and cost are greatly reduced, production efficiency is improve.Simultaneously, compared to bullet footstock, square cotter device, this device
Do not limited to by die space, be easier to realize.
