Abstract
Description
Technical Field
[0001] This utility model relates to the field of injection mold technology, and in particular to an injection mold with flow control function. Background Technology
[0002] In modern industrial production, molds, as key tools for product forming, are widely used in various fields such as plastic products, metal casting, and rubber products. Demolding injection molding is an important part of the mold production process, and its efficiency and quality directly affect the production cycle and final quality of the product. Existing molds do not have the function of flow control during the injection process, which makes it easy for the mold to inject too fast or too slow, resulting in damage to the workpiece. This reduces the processing efficiency and quality of the workpiece. To address this, we propose an injection mold with flow control function. Utility Model Content
[0003] To address the aforementioned problems, this invention provides an injection mold with flow control functionality. This invention solves the problem that existing molds lack flow control during injection, making them prone to over- or under-injection, which can damage the workpiece and reduce processing efficiency and quality.
[0004] This utility model discloses an injection mold with flow control function, comprising a lower fixed plate and an upper fixed plate. Partition plates are provided on both sides of the upper upper fixed plate, and a male mold plate is provided above the two partition plates. A female mold plate is provided in the middle of the lower part of the upper fixed plate. An upper mounting groove is provided in the middle of the lower end of the female mold plate. An upper module is provided in the middle of the upper mounting groove. An upper longitudinal guide groove is provided at the lower end of the upper module. Upper transverse guide grooves are provided on both sides of the upper longitudinal guide groove. Upper liquid inlet grooves are provided on both sides of the upper transverse guide grooves away from the upper longitudinal guide grooves. An upper mold groove is provided at the end of the upper liquid inlet groove. The male template has a lower mounting groove in the middle of its upper end, and a lower module is provided in the lower mounting groove. The lower module has a lower longitudinal guide groove in the middle of its upper end, and lower transverse guide grooves are provided on both sides of the lower longitudinal guide groove. Lower liquid inlet grooves are provided on both sides of the lower transverse guide grooves away from the lower longitudinal guide grooves. A lower mold groove is provided at the end of the lower liquid inlet groove. A cavity is opened at the lower end of the male template, and a mounting plate is provided at the lower end of the cavity. A hydraulic cylinder is provided in the middle of the lower part of the mounting plate. The stroke end of the hydraulic cylinder passes through the mounting plate and is fixedly connected to the push plate. A flow-blocking rod matching the upper liquid inlet groove and the lower liquid inlet groove is provided above the push plate.
[0005] In the above scheme, the upper module is provided with an upper side plate on its outer side.
[0006] In the above scheme, the lower module is provided with a lower side plate on its outer side.
[0007] In the above scheme, an injection port is provided in the middle of the upper part of the upper fixing plate.
[0008] In the above scheme, the mounting plate is provided with four guide rods arranged in a matrix outside the hydraulic cylinder, and the upper part of the guide rods is fixedly connected to the push plate.
[0009] In the above scheme, four positioning rods are arranged in a matrix below the mother template, and positioning holes matching the positioning rods are opened on the male template.
[0010] The advantages and beneficial effects of this utility model are as follows: This utility model provides an injection mold with flow control function. When the hydraulic cylinder is working, it pushes the push plate to move vertically. Through the transmission of the push plate, the flow-blocking rod also moves. The upper end of the flow-blocking rod is located inside the upper and lower inlet grooves. By adjusting the position of the flow-blocking rod, the gap between the guide holes formed by the upper and lower inlet grooves can be adjusted, thereby achieving the purpose of regulating the flow rate inside the mold. The upper side plate is fixed to the outside of the upper module, which facilitates the installation and disassembly of the upper module. The lower side plate is fixed to the outside of the lower module, which also facilitates the installation and disassembly of the lower module. This type of injection mold facilitates the installation and disassembly of components, and the flow rate during the injection process is easy to control, reducing the probability of workpiece damage and effectively improving the processing efficiency of the workpiece.
