Description
Technical Field
The utility model belongs to the technical field of injection mold, concretely relates to injection mold with easily demoulding structure.
Background
A mold is a tool used to make a shaped article, the tool being made up of various parts, different molds being made up of different parts. Injection molding is a process used to mass produce parts of some complex shapes. Concrete finger
The method is characterized in that plastic melted by heating is injected into a mold cavity at high pressure through an injection molding machine, a formed product is obtained after cooling and solidification, a demolding procedure is needed after the product is formed, the conventional demolding setting is that a thimble is used for direct ejection, but a product is difficult to eject after a plurality of products are formed, the product and the mold are easily damaged by forced ejection, and therefore the applicability and the practicability are limited.
Disclosure of Invention
The utility model aims at providing an injection mold who has easy demoulding structure that structure setting is reasonable and the suitability is strong.
The technical scheme for realizing the purpose of the utility model is that the injection mold with the easy demoulding structure comprises a lower die holder and a lower die fixed on the lower die holder, wherein a guide post and an upper die holder are fixed on the lower die holder, a guide round hole is arranged on the upper die holder, an upper die is fixed on the bottom surface of the upper die holder, a demoulding structure is arranged on the bottom wall of the lower die, the demoulding structure comprises a demoulding top post, a round cavity is arranged on the bottom wall of a die cavity of the lower die, a disc is fixed on the top of the demoulding top post, the disc is the same as the round cavity in size, a high-temperature resistant rubber layer is fixed on the top surface of the disc in a sticking way, the total thickness of the disc and the high-temperature resistant rubber layer is the same as the depth of the round cavity, a pore is arranged on the upper part of the side surface of the disc, and an air guide channel is arranged in the disc, the air outlet pore is communicated with the air guide channel, and the disc extrudes the high-temperature-resistant rubber layer when the demoulding top column rises and enables the air outlet pore to extend into the mould cavity.
And an air pressure regulating valve and an air pressure indicator are fixed at the bottom of the guide column.
The outer wall of the demolding top column is provided with a guide groove, a guide lug is fixed on the bottom wall of the mold cavity, and the guide lug is located in the guide groove.
And buffer springs are fixed on the top wall and the bottom wall of the guide groove.
The utility model discloses has positive effect: the utility model discloses a structure sets up rationally, and it is provided with the pore cooperation air guide channel of giving vent to anger, can let in the air before ejecting drawing of patterns, makes the chamber wall of product and bed die separate under the air current effect of air, then controls drawing of patterns fore-set rebound again with the ejecting realization drawing of patterns in the product follow bed die, and it is favorable to improving the efficiency of drawing of patterns, is difficult to damage the product in addition, is favorable to improving the quality of drawing of patterns, uses reliable and stable, and the suitability is strong and the practicality is good.
Drawings
