Specific implementation mode
The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, so as to make a clearer definition of the protection scope of the present invention.
It please refers to Fig.1 and Fig. 2, the embodiment of the present invention includes：
Embodiment 1
Present invention is disclosed a kind of dual-purpose type plastic moulds, including：Cope plate 1, lower template 2；The lower template 2 and the upper mold
The opposite one side of plate 1 carries mold cavity 3, is used to place with molding plastic raw materials in the mold cavity 3.
The cope plate 1 includes cope plate ontology 11 and reinforcing plate 12, and the reinforcing plate 12 is movable to be placed on described
The side opposite with the lower template 2 of template 1.
The cope plate ontology 11 includes cavity matrix 111 and core insert 112.The two side of the cavity matrix 111
Inner band has the block 4 to extend internally, the core insert 112 to carry protrusion 5 towards the side of the reinforcing plate 12.Specifically
Ground, the width of the core insert 112 are equal to the width between 111 inside relative wall of the cavity matrix；The core edge
The height of block 112 is less than the inner top surface of the cavity matrix to the height between 4 upper edge of the block.The height of the protrusion 5
Equal to the height of the block 4, the sum of width of the width of the protrusion 5 and 2 blocks 4 is equal to the cavity matrix
Width between 111 inside relative walls, the as width of the core insert 112.Above-mentioned core insert 112 is with the protrusion
5 are built in towards the direction of the reinforcing plate 12 in the cavity matrix 111, so that the block 4 of protrusion 5 and both sides is coincide and inlay,
The both sides holding of the i.e. described protrusion makes the lower edge of the protrusion 5 and the block 4 be total to straight line on the block.It is described
Multiple longitudinal springs 6, the longitudinal direction are also equidistantly installed between core insert 112 and the inner top surface of the cavity matrix 111
The top of spring 6 is fixed on the inner top surface of the cavity matrix 111, and bottom end is fixed on the top of the core insert 112.Institute
The foaming and intumescing volume that the mold cavity volume that the longitudinal compression of longitudinal spring 6 generates is equal to plastic products to be foamed is stated, it can be according to waiting for
The density conversion of foam plastic product obtains the decrement of longitudinal spring, different to be replaced according to different foaming plastics products
The longitudinal spring of compliant compression, to meet the requirement without density foaming plastics product.
In addition, the two side inner band of the cavity matrix 111 has outwardly extending first lug 7, the first lug 7
The lower edge of lower edge and the block 4 towards the lower template 2 is total to straight line.12 width of the reinforcing plate is more than or equal to described
Two opposite the distance between first lugs 7 of cavity matrix 111.
The lower template 2 carries outwardly extending second lug 8 towards the two side top of the cope plate 1.Described
One lug 7 and second lug 8 match, and utilize latch closure（It does not show）Fasten locking so that plastic raw materials are placed into mould
After having cavity, it can consolidate, be prevented because upper mold is not solid in subsequent movement and the exhaust of heating pressurized equipment, pressure process
Surely the phenomenon that causing product surface flaw.
Embodiment 2
Difference lies in described without the block 4 to extend internally on the inside of the two side of the cavity matrix 111 with embodiment 1
Core insert 112 is towards the side of the reinforcing plate 12 without protrusion 5.The face is horizontal structure.
The operation principle of dual-purpose type plastic mould of the present invention is：When for being molded non-foamed plastic products, it will enhance
Plate 12 is placed into the lower section of cope plate ontology 11, then will be upper by the fastening effect of first lug 7, the second lug 8 and latch closure
Mold and lower mold are fixed, and subsequent forming operation is carried out.Since non-foamed plastic products are in forming process, body not will produce
The phenomenon that product expansion, therefore, longitudinal bullet will be passed through by the use of reinforcing plate 12 between core insert 112 and cavity matrix 111
The case where compression of spring, masks, and ensures the normal molding of non-foamed plastic products.
When for shaping foam plastic products, reinforcing plate 12 is removed, in forming process, since plastic raw materials are because of hair
When infusion expanded by heating leads to volume expansion, core insert 112 can be jacked up upwards, to make longitudinal spring 6 compress, longitudinal bullet
Spring 6 compresses the expansion that the space vacateed is used for plastic raw materials, forms foaming plastics product.
A kind of dual-purpose type plastic mould of the present invention, simple in structure, reasonable design, by the structure design of upper module,
The mold cavity volume for being actually used in moulded plastic products of plastic mould is changed, to meet non-hair run plastic products and
The forming requirements of foam plastic product improve the application scenario of mold, reduce die cost, wide market.
In the description of the present invention, it should be noted that the instructions such as term "upper", "lower", "left", "right", "inner", "outside"
Orientation or positional relationship be based on the orientation or positional relationship shown in the drawings or the invention product using when usually put
Orientation or positional relationship, be merely for convenience of description of the present invention and simplification of the description, do not indicate or imply the indicated device
Or element must have a particular orientation, with specific azimuth configuration and operation, therefore be not considered as limiting the invention.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, and those skilled in the art is come
It says, the invention may be variously modified and varied.All within the spirits and principles of the present invention, any modification made by is equal
Replace, improve etc., it should all be included in the protection scope of the present invention.
