Abstract
The invention discloses a novel injection mold. The novel injection mold comprises an upper mold, a lower mold, positioning pins, positioning holes, springs, an inner baffle plate and an outer baffle plate, wherein the positioning pins are arranged at two short side edges of the upper mold; the positioning holes are formed in two short side edges of the lower mold; the springs are arranged between the positioning holes in the side edge of the lower mold; the inner baffle plate is arranged at the inner edge of the lower mold; the outer baffle plate is arranged at the outer edge of the upper mold; air vent holes are formed in the middle of the upper mold; a movable pin is arranged in the middle of each air vent hole; a sealing ring is arranged at the bottom end of each movable pin. The novel injection mold is simple in structure and reasonable in design; by virtue of the air vent holes, when the mold is internally heated in a closing process of the upper mold and the lower mold, air can be vented from the air vent holes, so that the pressure of internal air and external air is consistent, and the defects of a product are prevented; when raw materials are completely filled into the mold, the movable pins are blocked to prevent the raw materials from being leaked; by virtue of the inner baffle plate and the outer baffle plate, gaps of the mold are reduced, so that redundant parts of the raw materials cannot be leaked, and waste is reduced. The novel injection mold is suitable for energetic popularization and application.
Description
Technical field
The present invention relates to mould applications, particularly a kind of Novel injection mold.
Background technology
At present, existing injection mold is all upper and lower syntype, when mould closes up, during heating raw materials, the air of mould inside is not got rid of completely, easily cause the inside and outside pressure of mould inconsistent, make product produce flaw, especially, due to apertured existence between upper/lower die, raw material is easily leaked outside, cause raw-material waste, so existing injection mold also has very large improvement.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of Novel injection mold simple in structure, reasonable in design.
For addressing the above problem, the present invention adopts following technical scheme: comprise upper die and lower die, and be arranged on the alignment pin on the short side of patrix two, and be arranged on the locating hole on the short side of counterdie two, and be arranged on the spring between locating hole on counterdie side, and be arranged on counterdie inner side along the Internal baffle on limit, and be arranged on patrix outside along the outer baffle on limit, described patrix middle part is provided with steam vent, and described steam vent middle part is provided with removable pin, and described removable pin bottom is provided with sealing ring.
As preferred technical scheme: the thickness of described Internal baffle and outer baffle and with upper die and lower die side consistency of thickness.
As preferred technical scheme: described removable pin is up-small and down-big, section is for falling T-shape.
As preferred technical scheme: described alignment pin is evenly provided with six, and quantity is consistent with locating hole.
As preferred technical scheme: described spring is evenly provided with four.
The invention has the beneficial effects as follows: simple in structure, reasonable in design, by the setting of steam vent, when mould inside is heated, in patrix counterdie closing course, gas can be discharged by steam vent, make inner air and outer air pressure consistent, prevent that product from producing flaw, when raw material, at mould inside, fill when complete, removable pin is inaccessible, prevent that raw material from leaking outside, the setting of Internal baffle and outer baffle, the gap of having reduced mould, makes raw material can not spill unnecessary part, reduced waste, be applicable to vigorously promoting the use.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.

The specific embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention are made to more explicit defining.
Consult a kind of Novel injection mold shown in Fig. 1, comprise patrix 5 and counterdie 1, and be arranged on the alignment pin 3 on 5 liang of short sides of patrix, and be arranged on the locating hole 4 on 1 liang of short side of counterdie, and be arranged on the spring 2 between locating hole 4 on counterdie 1 side, and be arranged on counterdie 1 inner side along the Internal baffle 7 on limit, and be arranged on patrix 5 outsides along the outer baffle 9 on limit, described patrix 5 middle parts are provided with steam vent 6, described steam vent 6 middle parts are provided with removable pin 8, and described removable pin 8 bottoms are provided with sealing ring 10.
Wherein, the thickness of described Internal baffle 7 and outer baffle 9 and with patrix 5 and counterdie 1 side consistency of thickness.
Described removable pin 8 is up-small and down-big, and section, for falling T-shape, can utilize this structure that Bas Discharged mould is outside.
Described alignment pin 8 is evenly provided with six, and quantity is consistent with locating hole 4, has played the firm effect of fixing-stable, prevents displacement, causes product quality flaw.
Described spring 2 is evenly provided with four, has increased elasticity.
Simple in structure, reasonable in design, by the setting of steam vent, when mould inside is heated, in patrix counterdie closing course, gas can be discharged by steam vent, makes inner air and outer air pressure consistent, prevent that product from producing flaw, when raw material, at mould inside, fill when complete, removable pin is inaccessible, prevent that raw material from leaking outside, the setting of Internal baffle and outer baffle, the gap of having reduced mould, makes raw material can not spill unnecessary part, reduced waste, be applicable to vigorously promoting the use.
More than show and described basic principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present invention; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
