Abstract

The present invention provides a television set base injection molding mold with characteristics of easy use and good injection molding effect. The television set base injection molding mold comprises an upper mold, a lower mold, a molding cavity, a main flow channel and the like, wherein the upper mold and the lower mold are closed to form the molding cavity, the main flow channel is arranged inside the upper mold, the outer side of the main flow channel is provided with a pouring sleeve, the lower end of the main flow channel is vertically provided with a branch flow channel, the branch flow channel is communicated to the molding cavity through a gate, the lower end of the main flow channel is provided with a material cooling cave in an extending manner, an oil chamber is arranged inside the upper mold and is communicated to the molding cavity through an overflow port, and an injection molding member ejecting rod and a cooled material ejecting rod are arranged inside the lower mold. According to the present invention, the oil chamber is arranged, such that the lubricating oil can be injected into the molding cavity to lubricate the molding cavity so as to improve the quality of the molded member finished product and conveniently display the fullness degree of the melt inside the molding cavity, such that the condition that the incomplete melt pouring causes the defect of the molded member or the excessive melt pouring causes the waste of the melt is substantially avoided.

Description

A kind of television stand injection forming mold
Technical field
The present invention relates to television stand production equipment field, particularly relate to a kind of television stand injection forming mold.
Background technology
Injection mold is a kind of instrument of special production plasthetics, the complete structure of plasthetics and accurate size can be given, be widely used in the manufacture of television stand, existing injection mold is made up of dynamic model and cover half two parts, when injection moulding, dynamic model and cover half close and form running gate system and die cavity, during die sinking, dynamic model is separated with cover half and takes out plastic products, but the degree of filling of the melt of die cavity inside cannot be judged when pouring into a mould, often can produce the situation causing product defect or cast melt too much to cause melt to waste because cast melt is insufficient; And the surface smoothness of plastic is subject to the impact of the physical property of the die surface of melt contacts very large, greatly reduces the quality of plastic finished product.
Summary of the invention
According to above technical problem, the invention provides a kind of easy to use, the television stand injection forming mold that injection moulding is effective, comprise patrix, counterdie, die cavity, sprue, cast cover, cold slug well, runner, cast gate, plastic knock-pin, it is characterized in that: also comprise oil pocket, overflow lip, cold burden knock-pin, described upper die and lower die closed forming cavity, the inside of described patrix offers sprue, the outside of described sprue is provided with cast cover, the lower end of described sprue vertically offers runner, described runner is communicated with die cavity by cast gate, the lower end extension of described sprue offers cold slug well, the inside of described patrix offers oil pocket, described oil pocket is communicated with die cavity by overflow lip, the inside of described counterdie is provided with moulding knock-pin, cold burden knock-pin, described moulding knock-pin is connected with die cavity, described cold burden knock-pin is connected with cold slug well.
Described die cavity has N number of, N >=1.
Described overflow lip is arranged on the peak place of die cavity.
Beneficial effect of the present invention is: the present invention improves on original television stand injection forming mold, namely oil pocket is added, oil pocket is connected with the peak place of die cavity by overflow lip, lubricating oil can be injected in die cavity to lubricate die cavity, the defect that the physical property substantially reducing mold cavity surface during later stage cast produces plastic surface, improve the quality of plastic finished product, and in the process of injection moulding, the lubricating oil of die cavity inside can be clamp-oned in oil pocket from overflow lip by melt, then show that die cavity inside is full of melt when the height of the lubricating oil in oil pocket reaches mark, the degree of filling of the melt of die cavity inside can be shown easily, largely avoided the situation causing product defect or cast melt too much to cause melt to waste because cast melt is insufficient, also add cold burden knock-pin, the cold burden remained in cold slug well can be ejected, avoiding residual cold burden affects the situation that plastic part quality even blocks runner.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
According to Fig. 1, the present invention is further described:
As Fig. 1, patrix-1, counterdie-2, die cavity-3, sprue-4, cast cover-5, cold slug well-6, runner-7, cast gate-8, plastic knock-pin-9, oil pocket-10, overflow lip-11, cold burden knock-pin-12.
Embodiment 1
The present invention includes patrix 1, counterdie 2, die cavity 3, sprue 4, cast cover 5, cold slug well 6, runner 7, cast gate 8, plastic knock-pin 9, oil pocket 10, overflow lip 11, cold burden knock-pin 12, first sprue 4 is offered in the inside of patrix 1, cast cover 5 is arranged on the outside of sprue 4, then runner 7 is vertically offered in the lower end of sprue 4, cast gate 8 is arranged on the opposite side of runner 7, extend in the lower end of sprue 4 again and offer cold slug well 6, then oil pocket 10 is offered in the inside of patrix 1, oil pocket 10 is communicated with die cavity 3 by overflow lip 11, again by moulding knock-pin 9, cold burden knock-pin 12 is arranged on the inside of counterdie 2, moulding knock-pin 9 is connected with die cavity 3, cold burden knock-pin 12 is connected with cold slug well 6, finally by patrix 1 and counterdie 2 closed forming cavity 3, cast gate 8 is communicated with die cavity 3.
Embodiment 2
First patrix 1 and counterdie 2 are carried out matched moulds during use, lubricating oil is injected in oil pocket 10, then the lubricating oil in oil pocket 10 is full of die cavity 3 pairs of die cavities 3 by overflow lip 11 to lubricate, the defect that the physical property substantially reducing die cavity 3 surface during later stage cast produces plastic surface, again from the injection hole injection moulding melt of sprue 4 upper end, melt is through sprue 4, runner 7, cast gate 8 flows into the inside of die cavity 3, the lubricating oil of die cavity 3 inside is clamp-oned in oil pocket 10 from overflow lip 11 simultaneously, then show that when the height of the lubricating oil in oil pocket 10 reaches mark die cavity 3 inside is full of melt, at this moment just injection moulding can be stopped, both avoided due to cast that melt is insufficient causes product defect, it also avoid the situation of the melt waste that cast melt too much causes, then die sinking is carried out, by patrix 1, counterdie 2 is separated, by plastic knock-pin 9, plastic is ejected, by cold burden knock-pin 12, the cold burden in cold slug well 6 is ejected, avoid the situation of cold burden blocking runner.
The above is only the preferred embodiment of the present invention, it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention, can also make some improvement, and these improvement also should be considered as protection scope of the present invention.
