Skeleton mold of throat scalpel rack

Abstract

The invention relates to a skeleton mold of a throat scalpel rack. A lower die comprises a lower die plate, a lower die core, a plurality of floating inserts, a plurality of fixed inserts, a sinking plate, a top plate, an ejector pin, a strong pull rod, a secondary ejection mechanism and side forming assemblies, wherein the side forming assemblies are used for forming the left and right side surfaces of a product, the lower die core is fixed together with the lower die plate, the floating inserts are positioned in the lower die core and fixedly connected with the lower die core, the fixed inserts are fixedly connected with the sinking plate and movably inserted into the lower die core from bottom to top, the strong pull rod is fixedly connected with the top plate, the side forming assemblies are connected with the top plate, and the secondary ejection mechanism is connected with the top plate and the lower die plate. According to the skeleton mold, the secondary ejection mechanism is adopted, the inserts are divided into the floating inserts and the fixed inserts which are respectively separated from a product before and after demolding so as to guarantee that resistance received by the product is less when the inserts are separated from the product each time, the product is not deformed, the probability that the inserts are pulled broken is reduced, and the probability of insert sticking is also reduced. The skeleton mold belongs to the technical field of mold equipment.

Description

technical field [0001] The invention belongs to the technical field of mold equipment, and in particular relates to a skeleton mold of a scalpel holder for a throat. Background technique [0002] Medical devices refer to instruments, equipment, utensils, in vitro diagnostic reagents and calibrators, materials, and other similar or related items that are directly or indirectly used on the human body. Its effects are mainly obtained through physical methods, not pharmacological, immunological or metabolic methods, or although these methods are involved, they only play an auxiliary role; its purposes are: 1. Diagnosis, prevention, monitoring, treatment or 2. Diagnosis, monitoring, treatment, mitigation or functional compensation of injury; 3. Examination, replacement, adjustment or support of physiological structures or physiological processes; 4. Life support or maintenance; 5. Pregnancy control; 6. Samples from the human body are examined to provide information for medical o...

Problems solved by technology

At present, the surgical knife holder molds on the market generally do not meet the product requirements in terms of product appearance precision. At the same time, the rib spacing of the product mold is very small, the largest is 0.5mm, and the smallest is 0.2mm. It is difficult to grasp the spacing and the position of the glue mouth It is difficult to determine, so it is necessary to find a professional organization to analyze and simulate, list a variety of institutional plans, and perform multiple simulations to find the correct glue feed point, which is time-consuming, labor-intensive and resource-intensive

[0004] like figure 1 Shown is a kind of throat surgical knife holder commonly used in the medical field at present, figure 1 The dense knife holder holes shown in the middle are all used to install scalpels. The size of the holes is very small, and the lateral width is only 2-4mm. The wall thickness between adjacent knife holder holes is only 0.2-0.5mm, so The inserts on the mold forming the tool holder will be very thin and thin. Due to the large number of holes in the tool holder, the end of the insert will be subjected to too much tightening force when demolding, and the current mold is to push the product up at one time. In the process of product ejection, there are the following problems: 1. It is easy to cause the product to deform during the product ejection process

2. The insert is broken

3. There will be glue on the insert

4. There are many tool holder holes, and the molding cavity of the mold product is not easy to be filled with liquid
