Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-5, an injection mold with a rapid molding function includes a fixed mold 1, and the fixed mold 1 is used for molding an inner cavity of a container type product. When a product is injection-molded, a movable mold (not shown) is disposed to be engaged with the fixed mold 1, and the movable mold is used for injection-molding when the fixed mold 1 is closed and for molding a housing of a container type product after the injection is completed.
The fixed die 1 comprises a base 11 and an inner cavity forming part 12 convexly arranged on the top surface of the base 11, and the cross section of the inner cavity forming part 12 is in a circular arrangement. The cavity forming part 12 includes a first forming die 121 disposed on a top surface of the base 11, and a second forming die 122 is connected to the top surface of the first forming die 121. Preferably, the first forming mold 121 and the base 11 are integrally formed, so that the structure is more stable.
A cooling water inlet channel 123 vertically penetrates through the middle of the first forming die 121, a plurality of cooling water outlet channels 124 are formed at intervals from top to bottom on the edge portion of the first forming die 121, and the straight distance from each cooling water outlet channel 124 to the cooling water inlet channel 123 is consistent. When the first molding die 121 is coupled to the second molding die 122, the bottom surface of the second molding die 122 covers the cooling water inlet passage 123 and the cooling water outlet passage 124. The second molding die 122 has a communication chamber 125 formed in a bottom surface thereof, and the cooling water inlet passage 123 is communicated with all the cooling water outlet passages through the communication chamber 125. The bottom surface of the base 11 or the side surface of the base 11 is provided with a water inlet port 111 communicated with the cooling water inlet channel 123 and water outlet ports 112 corresponding to the cooling water outlet channels 124 one by one. After the movable mold and the fixed mold are closed and injected: the cooling water enters the cooling water inlet channel 123 from the water inlet interface 111, then flows to the cooling water outlet channel 124 after reaching the communication chamber 125 from the cooling water inlet channel 123, and finally is discharged from the water outlet interface 112.
The cooling water inlet channel 123 is located in the middle of the first molding die 121, and cooling water is introduced to the first molding die 121 so that the middle of the first molding die 121 starts to be cooled first, and heat at the edge of the first molding die 121 is uniformly transferred to the middle of the first molding die 121, thereby achieving the purpose of pre-cooling the container type product located outside the first molding die 121. The straight distances from each cooling water outlet channel 124 to the cooling water inlet channel 123 are set to be the same, so that the cooling water reaches the communicating chamber 125 and then is simultaneously distributed to each cooling water outlet channel 124, and the edge of the first molding die 121 is ensured to be simultaneously cooled. Under the condition of meeting the requirements of rapid cooling and rapid forming, the inner cavity of the container type product is uniformly cooled everywhere, the phenomenon of stress concentration is effectively reduced, and the formed product has better quality.
By the design of the cooling water outlet channel 124, while uniform cooling is satisfied, the travel time of the cooling water in the cavity forming part 12 is mainly as follows: the sum of the time of the stroke through the cooling water inlet channel 123, the time of the stroke through the communicating chamber 125, and the time of the stroke through one of the cooling water outlets to the channel 124. On the premise of meeting the heat absorption, the cooling water can bring the heat out of the inner cavity forming part 12 more quickly, so that the product is cooled and formed more quickly.
In order to facilitate separation of the movable mold from the fixed mold, the first molding die 121 has a cylindrical or truncated cone shape, and the second molding die 122 has a diameter smaller than that of the top surface of the first molding die 121. When the first molding die 121 has a truncated cone shape: the first molding die 121 is gradually tapered upward.
Further, at least 2 air passages 126 penetrate through the first forming die 121 and the second forming die 122 from top to bottom, and the air passages on the first forming die 121 correspond to the air passages on the second forming die 122 one by one. The bottom surface of the base 11 or the side surface of the base 11 is penetrated with air holes 113 which are communicated with the air passages 126 on the first molding die 121 one by one. After the movable mold is separated from the fixed mold, the inner cavity of the molded container product is easily attached to the outer sides of the first molding mold 121 and the second molding mold 122 and is not easy to take down, so that the air passages 126 and the air holes 113 are designed to enable the fixed mold to enable air flow to reach the top surface of the second molding mold 122 from a part of the air passages in an inflation mode after the container product is molded, and the fixed mold is led out from the other part of the air passages after the container product is pushed open, so that the purpose of increasing the gap between the inner cavity of the container product and the outer side of the inner cavity molding part is achieved, and the container product is further easy to take down from the fixed mold.
In the embodiment of the present invention, the top surface of the base 11 is formed with a positioning groove 114 surrounding the first forming die 121 for positioning the movable die.
Furthermore, the side wall of the positioning groove 114 is arranged obliquely outwards to form guiding, so that the movable mold can be closed with the fixed mold more easily.
It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
