[0002] Plastic casing molding is a key process in modern manufacturing, widely used in electronics, automobiles, home appliances, and medical devices. Different processes are suitable for different product requirements.
[0003] Injection molding is a common plastic shell molding process. It involves injecting molten plastic into a mold, cooling and solidifying it, and then demolding it. It has the advantages of high precision, suitability for complex structures, and support for mass production.
[0004] When the injection molding machine demolds, the detached product falls into the corresponding slot on the machine base. The product will pile up in the slot of the machine base, and the trolley for collecting the product is outside the machine base. It is inconvenient to push the product out of the slot.
[0005] In view of this, we propose a high-precision plastic shell molding device. Utility Model Content

A screw rod is threaded through the screw hole on the fixing block. A rotating handle is fixedly installed at one end of the screw rod. The positioning block is rotatably connected to the other end of the screw rod. The positioning block is U-shaped. The two protruding sections of the positioning block pass through the holes on the longitudinal section of the positioning plate, and the two protruding sections of the positioning block can be inserted into the positioning groove opened in the inner side wall of the groove.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1. This utility model, by setting a base plate, a feeding plate and a spring seat, has the advantage that the demolded product falls through the inclined feeding plate and is discharged from the groove onto the external collection trolley.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] The present invention provides two embodiments.
[0029] Example 1
[0030] Please see Figure 1 , Figure 2 and Figure 4 A high-precision plastic shell molding device includes a base 100, on which an injection system 300, a mold clamping system 400 and a hydraulic system 500 are arranged in sequence.
[0031] The injection system 300 includes a hopper, a screw conveyor mechanism, a feed cylinder, a nozzle, etc.
[0032] The mold clamping system 400 includes a mold clamping mechanism, a mold plate and tie rods, an ejection device, etc.
[0033] The hydraulic system 500 includes a hydraulic pump, control valve assembly, oil circuits, and oil tank, etc.
[0034] The above system is controlled by a PLC in conjunction with a sensor network.
[0035] A feeding system 200 is installed in a groove 101 on the base 100. The top opening of the groove 101 corresponds vertically to the demolding point of the mold closing system 400. The feeding system 200 includes a base plate 201 and a feeding plate 203. The base plate 201 is inserted into the groove 101, and the feeding plate 203 is positioned above the base plate 201. The feeding plate 203 is connected to the base plate 201 via a spring seat 204. The spring seat 204 includes a spring and a telescopic mechanism. The two ends of the telescopic mechanism are connected to the feeding plate 203 and the base plate 201, respectively, and the spring is sleeved on the telescopic mechanism. The feeding plate 203 is inclined and corresponds vertically to the demolding point of the mold closing system 400. When the product falls and impacts the feeding plate 203, the feeding plate 203 vibrates due to the spring seat 204, which helps to eject the product.
[0036] This utility model, by setting a base plate 201, a feeding plate 203 and a spring seat 204, has the advantage that the demolded product falls through the inclined feeding plate 203 and is discharged from the groove 101 onto the external collection trolley. This solves the problem that the product collection trolley is outside the machine base, and the product needs to be pushed out of the groove, which is inconvenient.
[0037] A baffle 205 is fixedly installed at the higher end of the blanking plate 203. The baffle 205 is located outside the groove 101 and is not obstructed by the groove 101. After demolding, the product that falls on the blanking plate 203 will not detach from the higher end of the blanking plate 203 after it bounces up.
[0038] Example 2
[0039] Please see Figures 2 to 5 A high-precision plastic shell molding device is disclosed, wherein L-shaped positioning plates 202 are fixedly installed at both ends of a base plate 201, and two insertion slots 102 distributed from top to bottom are respectively opened on the two inner side walls of the groove 101. The horizontal section of the positioning plate 202 can be inserted into the insertion slot 102. The horizontal section of the L-shaped positioning plate 202 can be inserted into the insertion slots 102 at different heights, thereby adjusting the height of the unloading plate 203, which is suitable for use with collection carts of different heights.
[0040] The positioning plate 202 is fixedly connected to the side wall of the groove 101 via the positioning assembly 206. The positioning assembly 206 includes a fixing block 2061 and a positioning block 2064. The fixing block 2061 is fixedly disposed on the bottom side of the base plate 201. A screw 2062 is threaded through the screw hole on the fixing block 2061. A handle 2063 is fixedly disposed at one end of the screw 2062. The positioning block 2064 is rotatably connected to the other end of the screw 2062. The positioning block 2064 is U-shaped. The two protruding sections of the positioning block 2064 pass through the holes on the longitudinal section of the positioning plate 202, and the two protruding sections of the positioning block 2064 can be inserted into the positioning groove 103 opened in the inner side wall of the groove 101. By inserting the two protruding sections of the positioning block 2064 into the positioning groove 103, the positioning plate 202 is fixed, thereby fixing the unloading plate 203 in the groove 101.
[0041] This utility model, by setting a fixing block 2061, a screw 2062, a rotating handle 2063 and a positioning block 2064, has the advantage of fixing the positioning plate 202, thereby fixing the feeding plate 203 in the groove 101 and keeping the feeding plate 203 stable.
[0042] Working principle: According to the height of the collection cart placement layer, the horizontal section of the positioning plate 202 is inserted into the corresponding insertion slot 102. Then, the operator rotates the handle 2063, the screw 2062 rotates and moves relative to the fixed block 2061, pushing the positioning block 2064 to move until the two protruding sections of the positioning block 2064 are inserted into the corresponding positioning slot 103.
[0043] After the molten plastic injected by the injection system 300 cools and solidifies in the mold of the mold clamping system 400, it is demolded. The demolded product falls onto the inclined discharge plate 203 and falls along the inclined discharge plate 203 onto the collection trolley placed outside the groove 101.
[0044] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
