Interior completion injection molding.In order to improve production efficiency, it is intended that more type chambers are arranged in unit area to manufacture product；But
It is that plastic cement has needed to cool down after being molded, gets too close to and will cause extend single processing procedure cooling time between type chamber, Na Youhui makes to give birth to
Producing efficiency reduces.
It is therefore desirable to develop the new mould structure of one kind to make production efficiency bigizationner.
Summary of the invention
The main purpose of the present invention is to provide a kind of small size synthetic resin part shaping mould, small-sized injection moulded pieces production efficiency can be allowed
It is higher.
The present invention is achieved through the following technical solutions above-mentioned purpose: a kind of small size synthetic resin part shaping mould, including upper mold is under
Mould, the lower die include the lower mode of rotation body structure, are evenly equipped with eight type chambers around axis on the lower mode, the upper mold includes
Hot runner manifold with hot flow path, the upper cores being fixed below the hot runner manifold, the upper cores have surround it is described under
The cylindrical part of mode, the cylindrical part are equipped with water delivery tank in the outside by plesiotype chamber, have the corresponding type in the upper cores
The glue injection cavities of chamber, hot mouth is contained in the glue injection cavities, and the hot mouth includes sealing, concave ring part and is located in the concave ring part
Tip, the concave ring part is equipped with the thread road for being connected to the hot flow path, and the glue injection cavities narrow toward type cavity direction, the point
It is directed toward the type chamber in portion.
Specifically, the glue injection cavities are also connected to the bigger seal chamber of internal diameter, the sealing position is in the seal chamber.
Further, the sealing includes the bulge loop for being held in the seal chamber bottom surface, the middle part tool of the sealing
Flexible distressed structure.
Specifically, array is placed with multiple lower modes in the lower die, the upper cores match one by one with the lower mode.
Specifically, the lower section of the type chamber has material demoulding hole, de- material is equipped in the material demoulding hole and is come directly towards.
By adopting the above technical scheme, the beneficial effect of technical solution of the present invention is:
It each descends mode that can form 8 small size synthetic resin parts in this mold, considerably increases the injection molding in unit area
Station in turn ensures cooling efficiency, can effectively improve production efficiency.

Specific embodiment
Invention is further described in detail combined with specific embodiments below.
Embodiment:
As shown in Figure 1 to Figure 3, a kind of small size synthetic resin part shaping mould of the invention, including upper mold (not shown) and lower die 1,
The lower mode 11 of lower die 1 including rotation body structure is evenly equipped with eight type chambers 111 around axis on lower mode 11, and upper mold includes having heat
The hot runner manifold 21 of runner 211 and the upper cores 22 for being fixed on 21 lower section of hot runner manifold, upper cores 22, which have, surrounds lower mode 11
Cylindrical part 221, cylindrical part 221 is equipped with water delivery tank 2211 in the outside by plesiotype chamber 111, has corresponding type chamber in upper cores 22
111 glue injection cavities 222, hot mouth 23 is contained in glue injection cavities 222, and hot mouth 23 includes sealing 231, concave ring part 232 and is located at recessed
Tip 233 in 232, ring, concave ring part 232 are equipped with the thread road 234 of connection hot flow path 211, and glue injection cavities 222 are toward type chamber 111
Direction narrows, 233 directing chamber 111 of tip.In this configuration, melt plastic cement can be entered by hot flow path 211, thread road 234
In glue injection cavities 222, then it is injected among type chamber 111 from the annular gap between 222 inner wall of tip 233 and glue injection cavities again.It walks
Sink 2211 is easy to process, will form the channel for leading to cooling water between cope plate.In the channel when water flowing, it will allow and lean on
11 periphery material of lower mode of plesiotype chamber 111 cools down, and the material in type chamber 111 is promoted to condense.Each lower die in this mold
Benevolence can form 8 small size synthetic resin parts, considerably increase the injection molding station in unit area, in turn ensure cooling efficiency, energy
Enough effectively improve production efficiency.
As shown in Fig. 2, glue injection cavities 222 are also connected to the bigger seal chamber 223 of internal diameter, sealing 231 is located at seal chamber 223
It is interior.Setting can increase the melt plastic cement in glue injection cavities 222 toward the distance of exosmosis in this way, be not susceptible to infiltration.
As shown in Figures 2 and 3, sealing 231 includes the bulge loop 2311 for being held in 223 bottom surface of seal chamber, sealing 231
Middle part has elastic deformation structure 2312.When assembly, bulge loop 2311 can be close to sealing under the action of elastic deformation structure 2312
The bottom surface of chamber 223 avoids machining accuracy problem bring from sealing not tight problem.
As depicted in figs. 1 and 2, array is placed with multiple lower modes 11 in lower die 1, and upper cores 21 and lower mode 11 are one by one
Match.Small size synthetic resin part can be placed on batch machining on large size plastic jetting-moulding device in this way, and production efficiency is higher.
As shown in Fig. 2, the lower section of type chamber 111 has material demoulding hole 112, de- material is equipped in material demoulding hole 112 and comes directly towards (not shown).
When injection molding is completed, de- material top can be penetrated in type chamber 111, by molding product from being wherein ejected, realize the automatic of de- material
Change.
Above-described is only some embodiments of the present invention.For those of ordinary skill in the art, not
Under the premise of being detached from the invention design, various modifications and improvements can be made, these belong to protection model of the invention
It encloses.
