Description

Technical Field

[0001] The invention relates to the technical field of injection molding, and in particular to a silicone product injection molding device. Background Art

[0002] Injection molding machine is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics. During the operation of the injection molding machine, the material must first be added to the feed barrel. In related technologies, a feed motor is usually used to extract the material into the feed barrel.

[0003] The patent with the publication number of "CN212400151U" is named as an automatic feeding device for a horizontal injection molding machine, which includes a storage box, a box cover is installed on the top of the storage box, a feeding pipe connected to the inside of the storage box is provided at the bottom of the storage box, a mounting seat is provided on the outer wall of the feeding pipe, a driving motor is installed on the mounting seat, the output shaft of the driving motor extends into the feeding pipe and a material control block is connected to the end thereof, and a stirring mechanism is provided in the storage box. The automatic feeding device for a horizontal injection molding machine drives the material control block to rotate by rotating the output shaft of the driving motor. When the material control block rotates to the horizontal direction, the feeding pipe is blocked. When the material control block rotates to the vertical direction, the feeding pipe is opened, and the raw materials begin to be fed through both sides of the material control block. No manual feeding is required, which improves the accuracy of feeding, reduces labor intensity, and improves work efficiency.

[0028] The equipment platform 1 is also provided with a telescopic driving mechanism 5 for driving the material transfer barrel 11 to move laterally closer to or away from the longitudinal support seat 51. The telescopic driving mechanism 5 includes a transverse telescopic cylinder 28 installed on the longitudinal support seat 51. The piston rod of the transverse telescopic cylinder 28 extends toward the barrel mounting seat 21 and is connected to the barrel mounting seat 21. When the injection mold 6 needs to be replaced, the injection mold 6 and the material transfer barrel 11 need to be separated. At this time, the transverse telescopic cylinder 28 extends out, driving the barrel mounting seat 21 away from the longitudinal support seat 51. The material transfer barrel 11 installed on the barrel mounting seat 21 can retreat from the longitudinal support seat 51 for replacement of the injection mold 6.

When the two blocking blocks 44 are in contact with each other, the blocking block 44 will be moved away from each other. At this time, the blocking block 44 will pop out along the blocking groove 43 under the elastic drive of the guide compression spring 47, and will not block the square hole 41; the limiting block 46 will slide in the limiting groove 45 to prevent the blocking block 44 from escaping from the blocking groove 43; in addition, when the two blocking blocks 44 are fitted together, the guiding protrusion 48 of one of the blocking blocks 44 will be embedded in the guiding inner groove 49 of the other blocking block 44, and the two blocking blocks 44 are tightly connected to ensure that the square hole 41 is blocked.
