Mould is arranged on above injection machine, and the plastics of molten condition are injected into the die cavity of injection mold by injection machine, and plastics are in mould
Intracavitary is cooled and shaped, and then the cover half of injection mold and dynamic model are separated, and the structure such as internal multiple core pullings is extracted out, makes product complete
Into the demoulding.
At present, its structure of the housing of refrigerator bottom is as shown in figure 1, it is a rectangular frame structure, and its section is
Hollow C character form structures.In order to which it can smoothly separate product from mold cavity, usual mold cavity configuration is designed to one
Individual rectangular frame structure, then sets multiple Loose core blocks, it is necessary to which then the Loose core block of inner side is extracted out one by one in inner side again
Product is ejected above die cavity using thimble come.
Because the interiors of products contact area of Loose core block and rectangular frame structure is larger, Loose core block is during core pulling
A stiction inside, and the easy deformation of rectangular frame structure can be produced, deformation inside easily occurs in product when the demoulding,
In turn result in damaged products.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of injection mold, by stopping
Structure hinders in core pulling product toward contract, and then quality when improving product stripping.
Above-mentioned technical purpose of the present utility model technical scheme is that：One kind is easy to product stable
Cover half, dynamic model are disposed with the injection mold of abjection, including mould bases, the mould bases from top to bottom, for driving product to take off
The top plate of mould, is provided with the Loose core block that insertion die cavity is provided with die cavity, the cover half between the cover half and dynamic model, described to take out
It is the hollow rectangular frame that section is C fonts that space is formed between pellet and mould intracavity wall, and the top plate on cover half with being provided with
The pitched roof mechanism taken out for Loose core block side, the pitched roof mechanism includes brace, and the Loose core block includes first be arranged oppositely for a pair
Loose core block, the brace runs through cover half, and described brace one end is connected with the second Loose core block, and being provided with the brace other end can
The relative slipping block slided, the slipping block is fixedly connected with top plate, and first Loose core block is embedded on cover half and first takes out
It is provided with the inclined-plane slided for the first Loose core block, the cover half and is provided through vertically on contact surface between pellet and cover half
Top margin push rod, described top margin push rod one end is fixedly connected with top plate, and the top margin push rod other end is fixedly installed top margin stop
Block, the top margin stopper side and the top edge inboard portion of C font die cavitys are contradicted.
By above-mentioned technical proposal, product is when abjection, and top plate is up moved, due to the presence of slipping block, top plate
The incline direction that brace can be directly pushed by slipping block makes it along itself drives the first Loose core block displacement, the first Loose core block
Banking motion can realize and eject product while core pulling.Meanwhile, top margin stopper is contradicted in the inboard portion of product,
Top margin stopper is linked vertically together by vertical top margin push rod with top plate, and then vertically movable in the lump with product, first
Loose core block hinders product sunken inside while being taken out toward inner side, allows product during core pulling, the demoulding in a stable shape
State, the quality of stable prod.
The utility model is further arranged to：The Loose core block also includes a pair of the second Loose core blocks being arranged oppositely, described
Second Loose core block is distributed on four inner surfaces of the die cavity of rectangle frame with the first Loose core block, and the pitched roof mechanism includes oblique
