Efficiency is higher.
The utility model is achieved through the following technical solutions above-mentioned purpose: a kind of small size synthetic resin part shaping mould, including upper mold
And lower die, the lower die include the lower mode of rotation body structure, are evenly equipped with eight type chambers, the upper mold around axis on the lower mode
Including the hot runner manifold with hot flow path, the upper cores that are fixed below the hot runner manifold, the upper cores, which have, surrounds institute
The cylindrical part of lower mode is stated, the cylindrical part is equipped with water delivery tank in the outside by plesiotype chamber, has corresponding institute in the upper cores
The glue injection cavities of type chamber are stated, contain hot mouth in the glue injection cavities, the hot mouth includes sealing, concave ring part and is located at the concave ring
Tip in portion, the concave ring part are equipped with the thread road for being connected to the hot flow path, and the glue injection cavities narrow toward type cavity direction, institute
It states tip and is directed toward the type chamber.
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 solutions of the utility model 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
The utility model is described in further 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 utility model, including upper mold (not shown) is under
Mould 1, the lower mode 11 of lower die 1 including rotation body structure are evenly equipped with eight type chambers 111 around axis on lower mode 11, and upper mold includes tool
There is the hot runner manifold 21 of hot flow path 211 and be fixed on the upper cores 22 of 21 lower section of hot runner manifold, upper cores 22, which have, surrounds lower die
The cylindrical part 221 of benevolence 11, cylindrical part 221 are equipped with water delivery tank 2211 in the outside by plesiotype chamber 111, have in upper cores 22 and correspond to
The glue injection cavities 222 of type chamber 111, hot mouth 23 is contained in glue injection cavities 222, and hot mouth 23 includes sealing 231, concave ring part 232 and position
Tip 233 in concave ring 232, 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
111 direction of chamber narrows, 233 directing chamber 111 of tip.In this configuration, melt plastic cement can pass through hot flow path 211, thread road 234
Into in glue injection cavities 222, then again from the annular gap between 222 inner wall of tip 233 and glue injection cavities be injected into type chamber 111 it
In.Water delivery tank 2211 is easy to process, will form the channel for leading to cooling water between cope plate.In the channel when water flowing, just
11 periphery material of lower mode by plesiotype chamber 111 can be allowed to cool down, the material in type chamber 111 is promoted to condense.It is every in this mold
A lower mode can form 8 small size synthetic resin parts, considerably increase the injection molding station in unit area, in turn ensure cooling effect
Rate can 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 utility model.For those of ordinary skill in the art,
Without departing from the concept of the present invention, various modifications and improvements can be made, these belong to practical
