Description

Technical Field

[0001] The utility model relates to the technical field of molding molds, in particular to a medical plastic rapid injection molding mold. Background Art

[0002] Medical plastic rapid injection molding molds use precision molds and injection molding technology to inject molten plastic materials into molds of specific shapes, and then form the required medical device parts after cooling and solidification.

[0003] Chinese patent publication number CN219256521U discloses a medical plastic rapid injection molding mold. In the process of driving the upper mold base to descend by a hydraulic rod, the utility model will synchronously drive the punching mechanism to punch holes in the accessories, thereby being able to simultaneously complete the stamping injection molding and punching operations. Compared with the existing method of first stamping injection molding and then punching, it can greatly shorten the processing cycle; when the upper mold base moves upward to separate from the lower mold base, the first roller moves to the oblique upper side of the first roller, and under the action of the spring, the punching rod automatically resets; therefore, the setting of the punching mechanism does not increase any work in the stamping injection molding operation.

[0004] During the injection molding process, in order to shorten the production cycle and improve production efficiency, the above-mentioned equipment adds a punching function after the injection molding is completed. This process reduces the workload of subsequent cleaning by quickly removing the residues in the bonding gap of the mold. Since the injection volume during the injection molding process is usually greater than the actual amount required for the product, there will inevitably be a certain amount of residual material in the bonding gap of the mold after molding. The existing air pump equipment can blow off most of the residues, but due to environmental factors such as humidity and temperature, some residues cannot be completely cleaned. These residues affect the quality of subsequent products to a certain extent, and may cause the product surface to be uneven or have defects, thereby affecting the aesthetics and functionality of the product. This needs to be optimized and improved. Utility Model Content

[0005] The purpose of the present invention is to provide a medical plastic rapid injection molding mold to solve the problem proposed in the background art that residues cannot be thoroughly cleaned, which to a certain extent affects the quality of subsequent products and causes uneven product surfaces or defects.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A medical plastic rapid injection molding mold, comprising:

[0008] The bottom connecting plate has a sliding groove on its top wall and a positioning block fixedly connected to the rear of the top end of the bottom connecting plate.

[0010] A blowing connection assembly, wherein a support assembly is installed on the top of the bottom connecting plate, and an upper mold assembly is connected to the inner side of the support assembly. The blowing connection assembly is arranged on the inner side of the upper mold assembly, and the blowing connection assembly includes a threaded tube, which is arranged at the inner top of the upper mold assembly, and a limiting block is connected to the outer side of the threaded tube. The blowing connection assembly can be slidably adjusted to blow at the inner top of the upper mold assembly.

[0011] Preferably, support blocks are installed on both left and right ends of the lower module, and buffer pads are bonded to the inner sides of the support blocks.

[0012] Preferably, the front end of the lower module is connected to a fixed installation block, and the front end of the fixed installation block is connected to a handle.

[0013] Preferably, the support assembly includes a support rod, and the support rod is fixedly connected to the top of the bottom connecting plate. A buffer spring is sleeved on the outer top of the support rod, and a connecting top plate is provided at the top of the support rod.

[0014] Preferably, the upper mold assembly includes an upper module, and the upper module is connected to the bottom end of the buffer spring. A movable slide groove is provided inside the upper module, and a telescopic cylinder is installed at the top of the upper module.

[0015] Preferably, the bottom end of the limiting block is connected to a receiving tube, and a tension spring is provided on the inner side of the receiving tube, and the bottom end of the receiving tube is connected to a blowing tube.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] The utility model supports the upper mold assembly through the support assembly, and then cooperates with the lower mold assembly to perform injection molding of medical plastic products. When the inside is difficult to clean, the lower mold assembly can be moved out through the sliding connection.

[0035] In this embodiment, the support block 503 cooperates with the buffer pad 504 to provide buffer support.

[0036] Specifically, such as Figure 3 As shown, the front end of the lower module 501 is connected to a fixed mounting block 505, and the front end of the fixed mounting block 505 is connected to a handle 506;

[0037] In this embodiment, the fixed installation block 505 can locate the position of the lower module 501 after it is moved, and the handle 506 facilitates the removal of the lower module 501.

[0038] Blowing connection component 7, the top of the bottom connecting plate 1 is equipped with a support component 4,

[0039] Specifically, such as Figure 2 As shown, the support assembly 4 includes a support rod 401, and the support rod 401 is fixedly connected to the top of the bottom connecting plate 1. The outer top of the support rod 401 is sleeved with a buffer spring 402, and the top of the support rod 401 is provided with a connecting top plate 403;

[0040] In this embodiment: the support rod 401 is in the middle, and supports the upper mold assembly 6 by connecting the top plate 403. The inner buffer spring 402 can provide buffering performance when moving up and down.

[0041] The inner side of the support assembly 4 is connected to the upper mold assembly 6.
