Description
Technical field
The utility model is related to mold design field, more particularly to a kind of high-precision silica gel diaphragm mould demoulding
Structure.
Background technology
Diaphragm (diaphragm), it is mainly used in valve, is used as the critical component of valve switch.Common
Diaphragm typically uses plastic cement manufacture, but the toxicity of plastic cement is stronger, not degradable, and poor chemical stability, heat-resisting quantity
Can be poor, service life is short, and its use in the field of high request is extremely difficult to requirement.
In present automotive field, diaphragm can be used on the part such as automobile oil filter valve, in order to solve to ask above
Topic, people begin to use silica gel to make diaphragm, and the toxicity of silica gel is weaker, environment-friendly degradable, and stable chemical performance, resistance to height
Warm nature can be more better than plastic cement, and service life is long.On the other hand, because the safety requirements of automobile is high, it is to internal part
Connection reliability and functional reliability are also very high, and are even more more last layer for the requirement of the critical components such as valve, therefore for vapour
The dimensional accuracy of car diaphragm typically required in below 0.01mm, to ensure that it can be accurately fitted at valve port and reliably work
Make.
Increasing with the demand of automobile, the demand of high accuracy silica gel diaphragm is also increasing now, and it is generally logical
Cross precision die and carry out injection molding acquisition, and found during processing, due to the thickness very little of silicone skirt piece, it is de-
Easily it is bonded in after the completion of mould on moving platen, it is necessary to removed using manpower or instrument, but such operation, easily damage
Injured labour product in itself, influence serious to the precision of product, reduce the production efficiency and quality product rate of product.
Utility model content
The purpose of this utility model is that providing one kind can be easy to product to depart from from moving platen, can't damage product
High-precision silica gel diaphragm mould demolding structure.
According to one side of the present utility model there is provided a kind of high-precision silica gel diaphragm mould demolding structure,
Including dynamic model, rear mold die and jacking block, wherein rear mold die is arranged in dynamic model, and jacking block is arranged in rear mold die, rear mold mould
Air flue is provided with benevolence, gap is provided between jacking block and rear mold die, gap is connected with air flue, jacking block is provided with forming surface, jacking block
It can move axially, so that forming surface is connected with gap.
The beneficial effects of the utility model are：In silicone skirt piece after being molded in forming surface, after the demoulding, silica gel is found
Diaphragm is bonded in forming surface, can be toward gas is passed through in air flue, and now, because gap is filled up by gas, jacking block is due to air pressure
Move axially so that forming surface is connected with gap, i.e., gas can be flowed in forming surface by air flue, and gas pressure is in silica gel
On diaphragm, silicone skirt piece stress comes off from forming surface completes the demoulding.The utility model is realized by air pressure to product
The demoulding, the uniform force of product, easy damaged product, not can guarantee that the high accuracy of product is high-quality.
In some embodiments, dynamic model includes dynamic model main body, thimble and side plate, and wherein thimble is arranged on dynamic model main body
It is interior, and be connected with jacking block, side plate is connected with dynamic model main body, and rear mold die is inlaid in side plate.Thimble is connected with jacking block, energy
Conveniently realize the axial movement of jacking block, it is ensured that jacking block, which is difficult to deviate, needs mobile position, and the setting of side plate can be protected preferably
Protect rear mold die.
In some embodiments, in addition to connector, connector is arranged in side plate, and is connected with air flue.Connection
The setting of head can facilitate the connection of air compressor machine, facilitate inserting for gas in air flue.
In some embodiments, side plate is provided with cavity, and connector is located in cavity.The setting of cavity can be protected preferably
Connector.
In some embodiments, annular air channel is provided with air flue.The setting of annular air channel can optimize the knot of rear mold die
Structure, prevents that certain partial intensities of rear mold die are too low, and can be easy to the processing of air flue.
In some embodiments, the section of jacking block is trapezoidal.Thus, jacking block can only carry out axial shifting in one direction
It is dynamic, better assure that jacking block moves reliability.
Brief description of the drawings
Fig. 1 faces for a kind of high-precision silica gel diaphragm mould demolding structure of embodiment of the present utility model
The sectional view of figure.
Fig. 2 is the enlarged drawing of Fig. 1 part A.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
With reference to Fig. 1 and Fig. 2, high-precision silica gel diaphragm mould demolding structure, including dynamic model 1, rear mold die 2, top
Block 3 and connector 4.
Dynamic model 1 includes dynamic model main body 11, thimble 12 and side plate 13.Thimble 12 is arranged in dynamic model main body 11, and side plate 13 leads to
Cross closing piece and be connected to the top of dynamic model main body 11, rear mold die 2 is inlaid in side plate 13.Cavity 131, connector are provided with side plate 13
4 are arranged in side plate 13, and in cavity 131.
Skewed slot is provided with rear mold die 2, the section of jacking block 3 is trapezoidal, the phase corresponding with the size and shape of skewed slot of jacking block 3
Match somebody with somebody, jacking block 3 is inlaid in the skewed slot of rear mold die 2, and jacking block 3 is also connected by bolt with thimble 12.Top after installation
Left between the skewed slot of block 3 and rear mold die 2 and air flue 21 is provided with gap 31, rear mold die 2, air flue 21 and connector 4 and gap
31 are connected.In addition, being additionally provided with annular air channel in air flue 21, annular air channel bypasses jacking block 3, to ensure the intensity of jacking block 3 simultaneously
Optimize the arrangement of air flue 21.
Jacking block 3 is provided with forming surface 32, and the jacking block 3 in rear mold die 2 makees movement somewhat in the axial direction, and
After jacking block 3 is moved upwardly by, the contacts side surfaces face of jacking block 3 and rear mold die 2 can reserve certain space, thus, forming surface 32
It can become to connect between gap 31.
When in use, connector 4 can be connected the utility model with air compressor machine, when high-precision silica gel diaphragm is in shaping
After face 32 is molded and is stripped, now, high-precision silica gel diaphragm can be fitted in forming surface 32 and be difficult to remove, user
Air compressor machine can be started, air compressor machine is by connector 4 toward air is injected in air flue 21, and air flow to jacking block 3 by air flue 21
In gap 31 between rear mold die 2, because gap 31 can be filled up by air, i.e., the pressure between jacking block 3 and rear mold die 2 increases
Greatly, jacking block 3 can make movement somewhat upward in the axial direction under the influence of air pressure, thus, between forming surface 32 and gap 31
The gas for occurring in tiny space, gap 31 can be by the spatial flow to forming surface 32 at, that is, flow to high precision silicon
The bottom of glue diaphragm, finally, high-precision silica gel diaphragm can be departed from forming surface 32 by effects of air pressure, that is, complete stripper
Make.
The utility model allows high-precision silica gel diaphragm to leave forming surface 32 by air pressure, even if high-precision silicone skirt
