The utility model relates to an injection mold with uniform injection material, including an upper mold and a lower mold, an injection mold cavity is arranged in the middle of the lower mold, an installation channel is arranged at the four corners of the lower mold, a supporting sleeve is arranged in the installation channel, and two ends of the supporting sleeve are provided with openings, and a positioning hole corresponding to the end of the supporting sleeve is arranged at the four corners of the upper mold. A thickened support sleeve is arranged between the upper die and the lower die, and a through hole is arranged at the four corners of the thickened support sleeve. The end of the support sleeve passes through the through hole of the thickened support sleeve and extends into the positioning hole at the bottom of the upper die. A support is arranged at the bottom of the lower die, and a cylinder is fixed on the support, and the cylinder rod of the cylinder passes through the support sleeve and extends. Inside the positioning hole of the upper die, the cavity in the middle of the thickened support sleeve is located directly above the injection cavity, thereby increasing the height of the injection cavity, which can appropriately change the size of the injection cavity, and has high operational flexibility.

一种注料均匀的注塑模具
本技术涉及模具领域，尤其是一种注料均匀的注塑模具。
技术介绍
注塑模具是一种生产塑胶制品的工具，也是赋予塑胶制品完整结构和精确尺寸的工具，注塑成型是批量生产某些形状复杂部件时用到的一种加工方法。具体指将受热融化的塑料由注塑机高压射入模腔，经冷却固化后，得到成形品，现在的注塑模具内的模腔在成型后就决定了注塑产品的形状以及具体的大小，注塑产品的厚度无法改变，主要是因为模腔的深度无法调节，实际注塑加工过程中，现在的注塑模具无法同时加工内部型腔一致但高度或厚度不同的注塑产品；现在的注塑模具在进行注料时主要通过注塑机来完成，注塑机一般采用螺杆注料或者液压注料，在实际注料的过程中会发现一些容易凝固的热熔塑料在注入到模具之前就存在部分凝结的问题，导致注塑的成品质量不佳，现在的注塑机无法克制这个问题，而且现在的注塑模具的模腔在注料时一般都是采用单注塑口进行注料，模腔内存在注料不均匀的问题，容易导致模腔内的部分区域出现热熔塑料凝固从而出现产品局部位置厚度过大而局部位置厚度小的问题。
